Koopa Troopa

"This shell was made to order. That's why it fits me so well. I mean, how cool do I look?"

- Koopa Troopa

Koopa Troopas (commonly shortened to Koopas or occasionally Troopas) are turtle-like creatures with removable shells that come in many different colors, with red and green Koopa Troopas being the most common; green Koopa Troopas usually walk back and forth without any concerns for pits or other obstacles, and red Koopa Troopas usually walk back and forth without falling off of their platforms. They are common enemies in the Mario franchise, usually displayed as foot soldiers of the Koopa Troop, under the direct leadership of Bowser. Since Super Mario 64, however, not all Koopa Troopas work for Bowser (or any other villain), some of whom even act as allies to Mario during his adventures, and have appeared as playable characters in various spin-off games starting with Super Mario Kart. They are notable for the many uses of their shells in the Mario franchise.

Koopa Troopas, along with Goombas, are Mario's most common foes.

Concept and creation
An enemy that first appeared in Mario Bros., the Shellcreeper, was the "ancestor" of the Koopa Troopa. When creating Super Mario Bros., a few changes were made to the enemies, including the ability to jump on them in order to damage them.

The Koopa Troopa's Japanese name, ノコノコ Nokonoko, refers to walking forwards slowly, describing their behavior. The English name comes from Bowser's Japanese name, クッパ　Kuppa, which is itself derived from the Korean dish of the same name, while Troopa is a corruption of the word "trooper," seemingly to keep the reference to forward marching from the Japanese name intact.

It is worth noting that the Koopa Troopas' ability to remove their shells is not true to any type of turtle, although popular culture often overlooks this fact.

Mario Bros.


In the game Mario Bros, there are enemies called Shellcreepers, which bear a huge similarity to Koopa Troopas, but cannot be jumped on. Shellcreepers come in three different colors to indicate their speed: green is the slowest, purple is slightly faster, and red is the fastest. The Shellcreepers are replaced by Spinies in most remakes of Mario Bros., likely so players know not to jump on them. In fact, the version of Mario Bros. included as a vs. battle in Super Mario All-Stars features normal Koopa Troopas alongside Spinies.

Super Mario Bros.
In Super Mario Bros., Koopa Troopas are the second enemy Mario encounters, directly after Goombas. They serve as foot-soldiers in the army Bowser uses to invade the Mushroom Kingdom. If jumped on, a Koopa recedes into its Shell, and can then be jumped on and used as a projectile with which to attack other enemies. If Mario gets hit by the shell it will revert him to small form or if he is already in small form he will lose a life. If left alone for too long, however, the Koopa rights itself. The game features two different types of Koopa Troopas: one is green (teal in underground levels except in the remake in Super Mario All-Stars) and it walks in one direction until it is defeated or falls, and the other is red and patrols a set area without walking off any edges. There is also a variation to the Koopa Troopa known as Koopa Paratroopas, which are flying Koopa Troopas. A Koopa Troopa is one of seven fake Bowsers that serve as the bosses of the castles in the first seven worlds. The fake Bowser of World 2's castle is a Koopa Troopa and like the other ones, its true identity will be revealed if it is defeated by fireballs.

Super Mario Bros.: The Lost Levels
Koopa Troopas reappear in Super Mario Bros.: The Lost Levels working exactly the same way as in the previous game. However, they walk faster than before, making them harder enemies for Mario or Luigi to handle. They can now be found underwater, where they cannot be stomped. Unlike the ones on land, these Koopas have gray shells like the gray Cheep Cheeps that are normally found underwater (but are colored normally in the SNES remake; red Koopas, along with other red enemies, remain the same color regardless of whichever palette is used), suggesting that green/orange enemies are always colored gray/orange when using the underwater palette, as evidenced by the fact that gray Cheep Cheeps were recolored green in Super Mario All-Stars.

Super Mario Bros. 2
Koopa Troopas do not appear in Super Mario Bros. 2 due to its role as a remake of the game Yume Kōjō: Doki Doki Panic. However, their shells do appear as items throughout the game, which can be used to hurl at enemies, like in the original Super Mario Bros. Unlike Super Mario Bros., they do not hurt the player; this is changed in Super Mario Advance.

Super Mario Bros. 3
Koopa Troopas make a reappearance in Super Mario Bros. 3. They are once again common foot soldiers in Bowser's army, although their reach is much wider in this game, as Koopa Troopas appear in nearly every Land Mario and Luigi visit. Super Mario Bros. 3 also allows the brothers to pick up a Koopa that had gone into its shell (a feature that will be present in later games), and to then throw it at enemies. In all of these games, Koopa Troopas walk on all fours except one Koopa in the game's ending sequence who appears to be praying at Statue Mario.

This game is also the first appearances of the Giant Koopa, which, like other giant versions of normal enemies in this game, can only be found on Giant Land, and Dry Bones, an undead version usually found in fortresses.

In the SNES version of Super Mario Bros. 3 (available in Super Mario All-Stars), Koopa Troopas also appeared in the Battle Game Mode. Unlike the Shellcreepers, the Mario Bros. can actually stomp on them. Therefore, Spinies fulfill the Shellcreepers' old role.

Super Mario Land
While Koopa Troopas do not appear in the first game of the series, Super Mario Land, similar-looking enemies known as Bombshell Koopas appear.

Super Mario World
Super Mario World marks many changes to Koopa Troopas. It marks the first time Koopa Troopas are seen walking on two legs in-game and wearing shoes (which later became the standard look for them). In this game, when a Koopa is jumped on, it is actually knocked out of its shell, becoming a Koopa without a Shell. Shortly after getting knocked out, it will become stunned and vulnerable for a short period of time. To reclaim its shell, a Koopa has to walk back to it before Mario grabs it. In this game, Koopa Troopas traveled with Bowser to Dinosaur Land in an attempt to take it over, though this plan is thwarted by the Mario brothers. This is the first game to introduce Koopas wearing Yellow Shells and Blue Shells. Also, if Yoshi eats certain color shells, then he will gain abilities: Green Shells do nothing, Red Shells allow Yoshi to spit fire, Yellow Shells allow Yoshi to cause a small earthquake every time the player lands after a jump, which defeats any enemies who are on the ground nearby, and Blue Shells allow Yoshi to fly for a short period of time.

The different color shells also point to the behavior of the Koopa Troopas. Blue-shelled Koopa Troopas act like red-shelled Koopa Troopas, but move faster. Additionally, when a blue-shelled Koopa loses its shell, instead of jumping into a new one, it'll kick any shell in its path. It also doesn't get stunned when it loses its shell, as it slides out on its feet as opposed to its belly like other Koopa Troopas. Yellow-shelled Koopa Troopas are unique and tend to chase after Mario, but act like faster green-shelled Koopa Troopas in movement. When yellow-shelled Koopa Troopas lose their shell, a coin pops out. Also, when a shell-less yellow-shelled Koopa finds a new shell, it will turn into a flashing Shell and chase Mario. It will be invincible to most of Mario's moves, however, Yoshi can eat this shell and gain all three shell abilities for a limited time, and a spin jump will also destroy this shell. Magikoopas can create yellow-shelled Koopa Troopas out of Rotating Blocks.

After the player completes the Special Zone, or find all exits in Super Mario World: Super Mario Advance 2, all Koopa Troopas (except climbers) become Mask Koopas, with their respective shells becoming round masks that vaguely resemble Mario.

Super Mario Land 2: 6 Golden Coins
Actual Koopa Troopas appear in Super Mario Land 2: 6 Golden Coins, and assist Wario in taking over Mario Land. These Koopa Troopas can be kicked at each other like in the Super Mario Bros. series, and they may right themselves after being jumped on. Koopa Troopas once again walk on all fours during these games. It is unknown what color of Koopa Troopas appear in the Super Mario Land series, as both of the games are in black and white; however, the behavior of the Koopa Troopas in the second game is identical to the normal behavior of the red-shelled ones, but the official artwork depicts them as green-shelled. A Koopa also appears at the entrance to the Turtle Zone.

Super Mario 64 / Super Mario 64 DS
Koopa Troopas make their 3D debut in Super Mario 64, where they appear as rare enemies only found in Bob-omb Battlefield and Tiny-Huge Island. They appear as members of Bowser's army which have invaded the portraits of Peach's Castle. Only green-shelled Koopa Troopas appear in this game. Unlike almost all of their other appearances, the Koopa Troopas in this game do not act aggressively towards Mario; in fact, they attempt to escape whenever they see him coming. If jumped on or punched, the Koopa Troopas will be knocked out of their shells and transformed into Beach Koopas. These Koopa Troopas are harmless and cannot hurt Mario, but they can push him back if touched. Attacking them in this state will defeat them, and they will yield a Blue Coin. Once the Koopa Troopas are knocked out of their shells, Mario can ride on their shells in a manner similar to surfing. Koopa shells can also be found in certain ! Blocks and clams. Additionally, a tiny Koopa appears in the tiny area of Tiny-Huge Island, but it cannot damage Mario and will be defeated if Mario attacks or even touches it.

A more friendly Koopa Troopa called Koopa the Quick also appears in Super Mario 64, in the same courses that regular Koopa Troopas are found in. This marks the first time an individual Koopa Troopa is given a name and differentiates from the species, as well as the first appearance of a Koopa Troopa who seems neutral to the battle between Mario and the Koopa Troop. When Mario speaks to Koopa the Quick, he gives a high-pitched whooping or hiccuping sound that goes on to be the iconic voice of all Koopa Troopas, especially in the Mario Kart series.

Koopa Troopas also appear in the remake of this game, Super Mario 64 DS. In this game, Koopa shells can also be found in some Brick Blocks. There is also a fully functional unused red Koopa Troopa that can be found in the game's codes. When they see the player, the red Koopa Troopas will run into them and knock them around, unlike the green ones. Their shell cannot be ridden, but can be kicked to hit other enemies. Yoshi can spew fire after eating a red Koopa Troopa.

New Super Mario Bros.
After being absent from Super Mario Sunshine, Koopa Troopas next appear in New Super Mario Bros. Their role is exactly the same as in the other sidescrolling Mario platformers; a ground pound, however, can send them into their shells and cause them to begin sliding. In New Super Mario Bros. there is a multi-player battlestage where a single Blue Koopa Troopa reappears for the first time since Super Mario World. If Mario attacks it, he can take the Blue Shell and become Shell Mario. The Koopa Troopas dance to the vocal riffs in the music's background.

Super Mario Galaxy
Koopa Troopas reappear in Super Mario Galaxy where they are semi-common enemies found mostly on the airship levels. Surprisingly, they are shown walking on all fours and do not wear shoes, unlike in most of the previous games. This makes it the first 3D platforming game to show them walking on all fours and also the eighth game since Super Mario Bros. for them to do so. They always have angry expressions. As in most games, there is a red and green type. The normal green type appears rather commonly, but there is only one red Koopa Troopa in the game, which appears near Sea Slide Galaxy's lighthouse. Defeating a Koopa (by throwing its shell away or breaking it) causes it to respawn in the same area it patrolled, making it the only enemy in the game to do so.

They do not flee from Mario unlike in Super Mario 64 and instead patrol a set area (in a straight line or in a circle). Also, unlike in Super Mario 64, Koopa Troopas can actually hurt Mario in this game. As usual, jumping on a Koopa or spinning into it will cause the Koopa to retreat into its shell. Like usual, waiting a bit will cause the Koopa to come out of its shell.

Koopa shells (both green and red) also appear as common items which can be thrown to defeat enemies and smash open chests or held onto underwater in order to swim faster.

An unused blue shelled variant of a Koopa Troopa can be found in the game files.

New Super Mario Bros. Wii
Koopa Troopas reappear in New Super Mario Bros. Wii, acting like they did in the first New Super Mario Bros. Koopa Troopas once again dance to the electronic vocal riffs in the background music by pausing and facing the screen, though they now do a bit of cha-cha. In this game, they appear in both green and red colored shell variations. The green Koopa Troopas will walk in a straight line until they reach a wall, but red Koopa Troopas turn around when they reach a drop in the ground. Koopa Troopas can be defeated by Spin Jumps and Ground Pounds, and therefore are much simpler to defeat than in earlier games.

Super Mario Galaxy 2
Koopa Troopas reappear in Super Mario Galaxy 2, and they act the same way as their predecessor. They only appear in the Cosmic Cove Galaxy, while Giant Koopas appear in the Supermassive Galaxy. Red Koopa Troopas do not appear in the game.

Super Mario 3D Land
Koopa Troopas reappear in Super Mario 3D Land as fairly infrequent enemies. Unlike the Super Mario Galaxy games, the Koopa Troopas have their current appearance back, walking on two legs in-game and wearing shoes, though only green Koopa Troopas appear, which is consistent with Super Mario Galaxy 2. They also seem to be a bit larger in this game, which, like the Goombas, make them easier to jump on. In the game, they appear to have more lighter blue eyes, while they have more of a dark navy blue pigment in their eyes.

Koopa Troopas are rare to encounter in the game, with only twelve appearing in the whole game, and are found in four levels (1-2, 1-3, 4-1 and S4-1). The behave similarly to their versions from previous games, where Mario stomps them and they can retreat into their shells so Mario can kick them to attack enemies. However, in this game, no matter how Mario attacks them, Koopa Troopas only retreat inside their shells when hit, though hitting them with another shell does destroy them. However, this only works if the Koopa that is hit hasn't retreated into its shell; hitting another shell results in that shell moving, and two shells in motion hitting each other simply rebound. Mario is unable to pick up their shells in this game. While retreated into their shells, Tanooki Mario can whip them with his tail or Fire Mario can shoot them with fireballs simultaneously five times to make the shell break open and reveal a 1-Up Mushroom. They appear as members of Bowser's Koopa Troop, which invaded the Mushroom Kingdom and kidnapped Princess Peach. Also, after the player has defeated Bowser for the last time, the Toads find a postcard that that has a picture of Luigi captured by a Koopa Troopa and a Peepa.

New Super Mario Bros. 2
Koopa Troopas reappear in New Super Mario Bros. 2, looking much like they have in the previous New Super Mario Bros. titles. In this game, when Mario touches a Gold Ring, Koopa Troopas turn golden for a time. When these golden Koopa Troopas' shells are tossed, a path of coins is created behind them wherever they go. Additionally, whenever a gold Koopa Troopa hits an enemy, and ascending number of coins are added to the player's coin count, depending on how many enemies are defeated.

New Super Mario Bros. U
Koopa Troopas reappear in New Super Mario Bros. U. They behave as in previous New Super Mario Bros. titles. Koopa Paratroopas and Big Koopa Troopas also appear.

Super Mario 3D World
Koopa Troopas return in Super Mario 3D World, with a more common appearance than in previous 3D Mario games. Here, they act differently from their appearance in Super Mario 3D Land by usually chasing Mario, like Goombas, rather than always walking back and forth in a straight line. They can also be removed from their shells like in Super Mario World. Koopa Troopas will try to get back into their shell if it is taken, and if they realize their shell has been lost, they express sadness for a moment and return to chasing Mario. They make the hiccuping sounds they make in spin-off installments and Super Mario Galaxy and Super Mario Galaxy 2.

Players also have the ability to climb inside abandoned shells, which will cause them to change color. This speedy form of transportation can be used to defeat other nearby enemies. There also appears to be a time limit for how long Mario and company can remain in these shells before they become dizzy and must exit them.

Super Mario Maker / Super Mario Maker for Nintendo 3DS
Koopa Troopas reappear in Super Mario Maker and Super Mario Maker for Nintendo 3DS as an enemy. They function exactly like they did in previous games, except in the New Super Mario Bros. U game style. In the Course Editor, they are enemies that can be placed. They start out as the green variants, but when they are shaken, they turn into the red variant. Like many enemies, they can be enlarged by a Super Mushroom and be given wings, and in the case of the latter they turn into Koopa Paratroopas. They can be placed in Bill Blasters, Warp Pipes, and Blocks.

When they are enlarged, their shells can break through blocks without bouncing. Koopa Shells are able to bounce on Trampolines and Note Blocks in this game. Exclusively in the Super Mario World game style, Koopa Troopas are turned into Beach Koopas when jumped on.

Super Mario Run
Koopa Troopas appear in Super Mario Run, which function like in the previous New Super Mario Bros. games. They retreat in their shells when Mario vaults over them, while stomping on them instantly sends the shell sliding, as they were already kicked or thrown.

Super Mario Odyssey
In Super Mario Odyssey, Koopa Troopas appear as non-playable characters rather than enemies, serving as hosts for minigames. Like in Super Mario 3D Land and Super Mario 3D World, they walk on two legs and wear shoes. Like most of the game's other non-playable characters, all of these Koopa Troopas are wearing irremovable hats, preventing Mario from potentially capturing them.

In the Sand Kingdom, Snow Kingdom, and Moon Kingdom, a Koopa Troopa (a red Koopa Troopa wearing a sombrero; a blue one wearing a snow hood; a purple one wearing an astronaut helmet, respectively) hosts the Trace-Walking minigame that involves Mario walking on a circle of arrows (a triangle for the Snow Kingdom version) that disappear after some time. If Mario gets 80 points, the Koopa Troopa gives him a Power Moon. After breaking the Moon Rocks in the respective kingdoms during the post-game, Mario can take on each trace-walking challenge again for more Power Moons should he score 90 points or more.

After completing the game, Mario can find a green Koopa Troopa in a cap that hosts the Koopa Freerunning mini-game, where Mario races a quartet of Koopa Troopas known as the Roving Racers, with the goal to reach a shining beacon at the end. Placing first rewards Mario with a Power Moon. Mario can race against the Roving Racers in every kingdom (excluding the Cloud Kingdom, Ruined Kingdom, Dark Side and Darker Side), and the environment of each kingdom is in the same state as when Mario first visits it (rainy in the Metro Kingdom, for example). After winning the Regular Cup and breaking the Moon Rock in the same kingdom, Mario can rematch the Roving Racers to collect a second Power Moon in the more difficult Master Cup version. In the Master Cup, a gold Koopa Troopa replaces the purple-shelled racer and often uses shortcuts to reach the goal. Interestingly, the Roving Racers have longer arms and legs to match Mario's body proportions.

In some kingdoms, Koopa Troopas appear as enemies in 8-bit segments. This makes them the only enemies to be exclusive to 8-bit segments, and the only ones to have a non-hostile counterpart.

Mario Clash
In Mario Clash, Koopas have a very important role. In this game, the only way to defeat enemies such as Thornies is to hit them with a Koopa shell. There are always two Koopas; if one Koopa falls of a cliff another will appear. They once again walk on four legs, and sometimes make a fanged "menacing" face that is identical to the one used by the related Shellcreepers in Mario Bros.

The Super Mario Bros. Super Show!
Koopa Troopas are the most frequently recurring minions in King Koopa's army on The Super Mario Bros. Super Show!. The Koopa Troopas are generally portrayed as being slightly slow and incompetent, although they are usually successful in carrying out simple jobs. The design used for Koopa Troopas on The Super Mario Bros. Super Show! was rather unusual, depicting them with green skin, green-rimmed shells, and beady eyes. It is possible that they were given green skin to better correlate with King Koopa's appearance. The Koopa Troopas on the show are depicted as bipeds, something that had yet to be seen in any game until Super Mario World. Also, as a joke, Koopa Troopas are usually seen wearing turtleneck sweaters.

In early episodes such as "King Mario of Cramalot" and "Rolling Down the River", Koopa Troopas speak in very slow, deep voices. However, in all of their later appearances, their voices, while still somewhat slow, are notably lighter.

In many episodes, a single, unnamed Koopa Troopa is shown to be a member of King Koopa's "Koopa Pack", which also consisted of Mouser and Tryclyde. There is never any indication of how this particular Koopa Troopa earned his rank in the Koopa Pack, as there is nothing to differentiate him from any other generic Koopa Troopa. This Koopa Troopa goes along with King Koopa's plots, and is usually dressed up in costume like King Koopa and many other minions to go along with the theme of the episode. He often battles Luigi and is then beaten by him.

Despite the prominence of Koopa Troopas throughout the show, Paratroopas only make one brief appearance in the episode "King Mario of Cramalot", and essentially look like red Koopa Troopas with bee-like wings.

In the episode "Princess, I Shrunk the Mario Brothers" it is shown that Koopa Troopas have a phobia over vegetables.

Super Mario World television series
While no Koopa Troopas ever appear on The Adventures of Super Mario Bros. 3, a single red Koopa Troopa makes an appearance in the Super Mario World episode "Fire Sale". This Koopa Troopa's design is truer to the games than that of The Super Mario Bros. Super Show!, and is based off of the Paratroopas that briefly appear in The Adventures of Super Mario Bros. 3 episode "Do the Koopa". This is also the only Koopa Troopa to appear in the follow-ups from The Super Mario Bros. Super Show!.

The Koopa Troopa in "Fire Sale" never speaks, and serves as Kootie Pie Koopa's lackey and personal punching bag throughout the episode. Near the beginning of the episode, Kootie Pie jumps on the Koopa Troopa repeatedly, knocking him out of his shell. When Kootie Pie throws the Koopa Troopa back into his shell, he winds up wearing the shell backwards, and is stuck like that for a good while. Despite the abuse he took, the Koopa Troopa has the last laugh towards Kootie Pie at the end, when she is frozen in a block of ice. The Koopa just reads a magazine and sips ice tea, ignoring Kootie Pie's complaints.

Super Mario World: Mario to Yoshi no Bōken Land
In the interactive OVA Super Mario World: Mario to Yoshi no Bōken Land, several Koopa Troopas appear under the command of Iggy, but they are defeated by Mario, Luigi, and Yoshi.

Nintendo Adventure Books
Koopa Troopas appear throughout the Nintendo Adventure Books, which gives them a weapon not seen anywhere else; a retractable cannon in their shells that allows them to bombard their enemies with a seemingly limitless barrage of empty Koopa Shells.

The only noteworthy role Koopa Troopas have in the series is in the twelfth and final book, Brain Drain. Due to Iggy Koopa's Synapse Switcher, Luigi can switch minds with one, allowing him to go undercover in Iggy's hideout. While in the Koopa Troopa's body, Luigi also discovers that pizza tastes disgusting to them.

Super Mario Adventures
Several Koopa Troopas appear in the Super Mario Adventures comic book, which was loosely based on the Super Mario World video game. In this comic, Koopa Troopas first appear during Bowser's initial attack on Peach's Castle. They are among the many enemies that come through Warp Pipes and attack the Mario Bros.

After the supposed rescue of Princess Peach from Wendy O. Koopa's castle, Toad is sent back to the Mushroom Kingdom with the aid of a Cape to get a rescue party for the Mario Bros. and the Princess. He is waylaid by Bowser and several Koopa Troopas masquerading as Toads, who aid Bowser during Princess Peach's second abduction in that story.

Mario is Missing!
Koopa Troopas accompany Bowser and the Koopalings to the Real World during the events of Mario is Missing!. In this game, Bowser sends Koopa Troopas to different cities throughout Earth, where they wreak havoc by stealing precious artifacts from various museums and national monuments. Before Luigi can advance through Bowser's Castle, he must return every missing artifact to its place. The Koopa Troopas in this game do not resist Luigi's attacks, and it is impossible to be hurt by them. When jumped on, the Koopa Troopas without artifacts disappear, while the ones carrying artifacts disintegrate into dust. This disintegration was a style commonly used in cartoons, where the body of a creature turns to dust until only its eyes remain. The eyes blink once, and then disappear.

Mario's Time Machine
In Mario's Time Machine, Koopa Troopas have to be defeated so Mario can get an item and warp to other times in history. They act just like the Koopa Troopas in Mario is Missing.

In the NES version, red-shelled Koopa Troopas are found in a Mario Bros.-style arena to obtain the item, then yellow-shelled ones are found within the various time periods. Here, they act as they do in the main series, and are accompanied by Bodyslam Koopas, heavyweight Koopa Troopa variants. On the Moon, Koopa Troopas wear space helmets, which cover the tops of their shells whenever they retract into them.

Mario Kart series
A Koopa Troopa first appears as a playable character in Super Mario Kart, where he is a lightweight whose special item is a Koopa Shell. Koopa Troopa is one of the fastest characters with little traction in Super Mario Kart.

In Mario Kart: Super Circuit, green and red Koopa Troopas can be seen at the awards ceremony at the end of a Grand Prix.

A green Koopa reappears in Mario Kart: Double Dash!! where he is partnered with a red Paratroopa, and their special items are the Triple Shells, either Green Shells or Red Shells. Koopa's kart in this game is the Koopa Dasher.

In addition to their numerous playable appearances, Koopa Troopas also cameo in both Mario Kart Arcade GP 2 and Mario Kart Arcade GP DX. In the latter game, one can be seen walking around near the starting line of one of the courses.

A Koopa is playable in Mario Kart Wii, where he is given an outstanding Mini-Turbo bonus that is rivaled by Dry Bowser's, Dry Bones', and Wario's; he also is given a small handling bonus and is given a representative course called Koopa Cape.

Koopa Troopa also appears as a playable racer in Mario Kart 7, for the Nintendo 3DS. He is a Feather class racer, with acceleration and off-road being his best stats.

Koopa Troopa returns as a default playable character in Mario Kart 8. He is a lightweight character, although he is one of the heavier lightweights, meaning his speed and weight are slightly better than that of the lightest lightweights at the expense of acceleration, handling, and grip, making him more balanced. He has the same stats as Toad, Toadette, Shy Guy, Lakitu, Larry Koopa, Wendy O. Koopa, and Isabelle. Koopa Troopa also appears on some of the posters for the sponsor Galaxy Air.

Koopa Troopa is the Normal Staff Ghost for DS Cheep Cheep Beach.

Koopa Troopa returns in the Nintendo Switch port Mario Kart 8 Deluxe. This time, he shares stats with Lakitu and Bowser Jr. If he is a CPU, he uses the Steel Driver or Sport Bike.

Koopa Troopa appears in Mario Kart Tour as a Normal-class driver. His special item is the Triple Green Shells. On December 3, 2019, as part of the London Tour, Koopa Troopa received an alternate costume variant known as Red Koopa (Freerunning), based on the red Roving Racer in Super Mario Odyssey. He is a Super-class driver, and his special item is the Fire Flower.

Yoshi's Safari
A single Koopa Troopa enemy appears in Yoshi's Safari, to aid Bowser in his invasion of Jewelry Land. This Koopa Troopa appears as the penultimate boss in the game, fighting in a giant robot made in the likeness of a Koopa. It has a gun turret manned by four Koopa Troopas. Several Koopa Shells appear as enemies throughout the game, however these may not have actually contained Koopa Troopas, as none are seen.

Hotel Mario
Koopa Troopas, known as Koopas reappear in Hotel Mario as enemies along with Flying Koopas, Skeleton Koopas, Mecha Koopas, and a variant of Flying Koopas called Z Koopas. In this game Koopa Troopas would open doors which Mario has to close.

Mario Tennis series
Before his playable debut in the Mario Tennis series, Koopa Troopa made an appearance as a playable character in Mario's Tennis for the Virtual Boy, which features every playable character from Super Mario Kart except Bowser.

Mario Tennis
In Mario Tennis for the Nintendo 64, four Koopa Troopas are present during Paratroopa's trophy celebration, where they congratulate him. They also appear in the background of many courts.

Mario Power Tennis
Koopa Troopa reappears in Mario Power Tennis as a playable character, where he is classified as speedy. His Offensive Power Shot is the Water Bomb, where Koopa performs a special drop shot that forces the characters to get close to the net. His other special move, the Defensive Power Shot named Water Shell Dash, consists of saving the loose ball by hiding into his shell and homing in to the ball to make the return. Paratroopa is also present in this game. Koopa Troopa's default partner is Yoshi.

Koopa Troopa's Mario Power Tennis trophy animation begins with him walking on stage with Luigi, Mario and Peach cheering for his victory; Diddy Kong is also there, eating bananas. He then throws a banana peel in Koopa Troopa's path. Mario, Luigi and Peach try to warn him, but he slips onto his back and slides across the stage, ricochets off a pole and hits Luigi in the head, making him drop the trophy. Koopa Troopa then catches it.

Mario Tennis Open
Koopa Troopas are seen in Mario Tennis Open as line judges in the Mushroom Valley court.

Mario Tennis Aces
Koopa Troopa appears in Mario Tennis Aces as an opponent in the mission Battle Boat in Adventure Mode. Koopa Troopa is also a playable character, classified as a Speedy character. As of August 1, 2018, he was made available to all players, although participants of the July 2018 online tournament could play as Koopa Troopa earlier.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Koopa Troopas also appear, albeit less frequently, in Super Mario World 2: Yoshi's Island, a prequel to the entire Mario series. In this game, Shy Guys largely replace Goombas and Koopa Troopas as the game's most persistent foes; while Shy Guys appear in almost every level, Koopa Troopas are much rarer. They first appear in the level Visit Koopa And Para-Koopa. In this game, only red and green shelled Koopa Troopas appear, and neither walk off the side of cliffs. Like in Super Mario World, these Koopa Troopas can be knocked out of their shells. There is also a boss Red Koopa Troopa in this game named Hookbill the Koopa. He first starts out as a Red Koopa Troopa, but is then put under Kamek's spell, turning Hookbill into a much larger Koopa Troopa that walks on all fours.

Tetris Attack
Hookbill the Koopa reappears in Tetris Attack as an enemy.

Yoshi's Island DS
Koopa Troopas and Para-Koopas reappear in Yoshi's Island DS as enemies. They look similar to their appearance in the SNES predecessor, but with a much lighter outline and a slight increase in size. Like in the previous game, if stomped on, the Koopa Troopas are kicked out of their shells.

Yoshi's Woolly World / Poochy & Yoshi’s Woolly World
Red Koopa Troopas reappear in Yoshi's Woolly World and its 3DS remake. When a Red Koopa Paratroopa is hit with a yarn ball, it will turn into a Red Koopa Troopa. 8-bit Koopa Shells can sometimes be found in walls with strings. When Yoshi licks the strings, the Koopa Shell will come out and it can be used like a normal shell.

Yoshi's Crafted World
Koopa Troopas return as enemies in Yoshi's Crafted World. They only appear in the level, Many Fish in the Sea, with the green shelled variants walking off the side of cliffs, while the red shelled variants do not.

Super Mario RPG: Legend of the Seven Stars
Koopa Troopas are absent from Super Mario RPG: The Legend of the Seven Stars, seemingly replaced by Terrapins, which are basically armored Koopa Troopas, similar to Koopatrols. However, many four-legged Paratroopas are present in the game, including the Heavy Troopa and Tub-O-Troopa.

Mario Party series
Beginning with Mario Party, Koopa Troopa's most frequent role in the Mario Party series has been the proprietor of the Koopa Bank or the Koopa Bank Capsule, a location which both takes and gives coins to and from the Player. A Koopa Troopa appears as Mario's starting partner in Battle Mode in Mario Party 3. Throughout the series, they appear as background characters in boards and minigames.

Mario Party
Koopa Troopas appear in the first Mario Party game to award the player with ten Coins each time the player passes the starting point (in a similar style to the game Monopoly). Four Koopa Troopas appear in the minigame Shell Game, were the player needs to find the Koopa Troopa who has the treasure chest with coins inside it. In Bowl Over, the solo player uses a Koopa Shell in order to knock over the three other players. An item called No Koopa can be bought in the item shop in Mushroom Village for 500 coins. The item causes the Koopa Troopa to not appear near the start of the boards.

Mario Party 2
A Koopa Troopa appears in the introduction of Mario Party 2 trying to warn the characters of Bowser's attack. One Koopa Troopa hosts the Koopa Bank, and another one hosts the Item Shop in this game. In Tile Driver, one of the pictures that sometimes needs to be made is a Koopa Troopa. Bowl Over also reappears in this game. A Koopa Troopa also appears in the ending of each board, being attacked by Bowser and the winning player rescues the Koopa Troopa before facing Bowser.

Mario Party 3
A Koopa Troopa appears as Mario's starting partner in Battle Mode in Mario Party 3. Koopa Troopa has one attack and two HP, and its salary is one coin. They also host the Koopa Bank once again. Koopa Troopas, along with Goombas and Boos appear in the minigame Curtain Call, where the players need to memorize the order in which the Koopa Troopas, Boos and Goombas appear. In the minigame Slot Synch, getting a Koopa Troopa on the Dice Block will give a team two points. In Three Door Monty, the players needs to answer which door the Koopa Troopa, Boo, or Toad enters. The player who answers the fastest wins.

Mario Party 4
Koopa Troopa is one of the hosts that organized the party with the Party Cube, along with Toad, Shy Guy, Boo, and Goomba. He sports a Hawaiian shirt and is the host of his board, Koopa's Seaside Soiree and the option room. The Koopa Troopa made this board because he always wanted to own his own resort. He always appears to be laid back as well. Koopa Troopas (and related species) also appear in the following minigames: Paratrooper Plunge, where the characters have to avoid red Paratroopas, GOOOOOOOAL!!, as a member of the crowd Kareening Koopas, where in Story mode, he's the opponent fought against and as an unlockable character in the Beach Volley Folley minigame.

Mario Party 5
The Koopa Bank returns in Mario Party 5. In the minigame Flower Shower, two Koopa Troopas exit a church, and then the red Koopa Troopa will throw a bouquet up in the sky. The players need to collect as many flowers as they can within the time limit. In the minigame Triple Jump, a Koopa Troopa is standing next to the 90-foot marker. Koopa Troopas also appear in the background in Random Ride.

Mario Party 6
Koopa Troopas appear in the board Faire Square, hosting many of the board events. Koopa Troopas also appear in the background in Odd Card Out and Lab Brats. Koopa Troopas also take care of the Orb Shops during the day, while Shy Guys take care of it during the night.

Mario Party 7
Koopa Troopas take care of the Orb Shops in Pagoda Peak and Windmillville. Also in Pagoda Peak, a Koopa Troopa named Koopa Master lives at the top of the peak, where he sells stars to players for 10, 20, 30, or 40 coins.

Mario Party Advance
A Koopa Troopa named Koopa appears as the manager of the Town Koopa Bank, and is also the cousin of Paratroopa. Generic Koopa Troopas also appear in the minigames Floor It!, where they are one of the four species that must be brought to their respective floors, and Watch 'Em, where a Koopa Troopa hides in one of three Warp Pipes, and the player must guess which one contains it.

Mario Party 8
In Mario Party 8, there is a somewhat notable Koopa Troopa called Holly Koopa who is quite minor in Shy Guy's Perplex Express, giving out money in exchange for candy when a player lands on her Green Space. In Star Battle Arena however, players must get 50 coins to her to win the match. Some other Koopa Troopas are found occupying the seats. Koopa Troopas also have their own board named after them in Koopa's Tycoon Town. Koopa Troopas are found nearly everywhere in this board from being bellboys to sitting on park benches. Some also act as taxis to get places. A Koopa Troopa is the main baker in Sugar Rush, a minigame. Other minigames they are in include Picture Perfect where a flying Red Shell is one of the pictures, Blazing Lassos where they make a cameo, Breakneck Building in another cameo, Specter Inspector as an enemy to find, audiences in Fruit Picker, Pour to Score, Stampede, a biker in Moped Mayhem, and finally the proprietor in the Surprise Wagon and the music maker in the Carnival Calliope.

Mario Party DS
An unnamed Koopa Troopa and his grandfather, Koopa Krag, had major roles in Mario Party DS. In the game, Koopa Krag is trapped in a book by Kamek in Kamek's Library. While Mario and friends are heading for Bowser's Castle to get back to their normal sizes, Koopa shows up, requesting to the player to save his grandfather and defeat Kamek. After winning the party, the boss minigame features the player riding the magic book Koopa Krag was trapped in to face Kamek, by shooting ink blots from a pen at his face while avoiding Kamek's books. Once Kamek is defeated, Koopa Krag will return to normal and thank the player by giving them a Sky Crystal.

Mario Party 9
A Koopa Troopa appears as a starting playable character in Mario Party 9. This marks the character's first time in the series as a fully playable character. Some other Koopa Troopas also appear in several minigames. There is a constellation of a Koopa Troopa's shell called "Speedy Shell," purchasable at the Museum for 50 Points.

Mario Party: Island Tour
Koopa Troopas reappear in the game Mario Party: Island Tour for the Nintendo 3DS. One appears in a bubble in the minigame Spin the Bubble. Others appear as tiles in the minigames Match Faker and Tap Dash. One also appears as a constellation in the minigame Starring Artist.

Mario Party 10
Koopa Troopas reappear in Mario Party 10 for the Wii U. They act as non-playable characters. They can be seen in some minigames and in the Mario Board.

Mario Party: Star Rush
Koopa Troopas are again minor characters in Mario Party: Star Rush. They appear in a few minigames, such as in Pop Quiz where they are selectable enemies in a few questions.

Mario Party: The Top 100
Koopa Troopas also appear in Mario Party: The Top 100, reprising their roles in the minigames Three Door Monty, GOOOOOOOAL!!, Dinger Derby, Triple Jump, Ice Hockey, Slot Trot, Dart Attack, Jigsaw Jumble, and Soar to Score. They also replace the Shy Guys in Blame It on the Crane. Additionally, a Koopa Troopa amiibo can be scanned for bonus coins in Minigame Island, and a Koopa Troopa stamp can be collected in Minigame Match.

Super Mario Party
A Koopa Troopa appears as a playable character in Super Mario Party, making his second playable appearance in the series. His special Dice Block, the Koopa Troopa Dice Block, can roll 1, 1, 2, 3, 3, or 10. Red Koopa Troopas also appear as non-playable characters found in the background of some minigames.

On the game's official website, Koopa Troopa was erroneously listed as Koopa Trooper. This has since been fixed.

Mario Golf 64
Though not playable, Koopa Troopas do appear in the original Mario Golf for the Nintendo 64.

Mario Golf: Toadstool Tour
A Koopa Troopa appears as a playable character in the game Mario Golf: Toadstool Tour. In the opening movie, he is seen playing and then napping alongside Yoshi. This may be a reference to them being default partners in Mario Power Tennis. Koopa Troopa has the best Impact and Control of any character, but he has the worst drive distance out of any character.

Mario Golf: World Tour
Koopa Troopas appear in Mario Golf: World Tour as NPC characters in the Castle Club mode. Also, Koopa is one of the names that can appear on the tournament scoreboard.

Paper Mario
Several Koopa Troopas appear in Paper Mario, both as enemies and allies. All of the enemy Koopa Troopas in this game have red shells, a pair of sunglasses, and spiked, black arm bands and collars, like Bowser. These Koopa Troopas aid Bowser in his plot to kidnap Princess Peach. In this game, Koopa Troopas are shown to be quite resilient, as they have a fair defense (full damage can only be dealt once they are flipped onto their backs) and have the ability to withdraw into their shells and shoot themselves at their opponents. It is also the first enemy to make the First Strike and if Mario gets hits outside battle with this enemy, the player cannot use the action command meaning Mario will have to take damage.

The "good" Koopa Troopas all live in Koopa Village, a place which is overrun by Fuzzies at one point in the game. After Mario and Goombario get rid of all the Fuzzies they become quite popular in the village (the Koopa Troopas even send a letter to Mario later in the game, thanking him and apologizing for not rewarding him). One Koopa Troopa, Kooper, joins Mario's party to aid him in his fight against Bowser after Mario gets his shell back from the Fuzzies. There is also a baby Koopa Troopa by the name of Jr. Troopa, who constantly stalks Mario and his allies to pick fights with them for intruding on his playground early in the game. He also makes a very small cameo in the sequel Paper Mario: The Thousand-Year Door.

Paper Mario: The Thousand-Year Door
The red-shelled sunglasses-wearing style of Koopa Troopa was carried over to Paper Mario: The Thousand-Year Door as common enemies, despite Bowser not being the main antagonist of that game. In fact Bowser himself may encounter some Koopa Troopas during the parts of the game where he can be played as, though they all run away from Bowser when he approaches them. The "good" Koopa Troopas in Paper Mario: The Thousand-Year Door live in Petalburg. These "good" Koopa Troopas in this game are more true to the original Koopa Troopa appearance, with green shells and no shades or collars. Mario once again receives a Koopa Troopa partner, Koops. It is also mentioned that a heroic Koopa, presumably a Koopa Troopa, was one of the original four heroes who defeated the Shadow Queen; this Koopa's spirit is encountered at Keelhaul Key, as one of the four Black Chest Demons.

In this game, the evil Koopa Troopas are first seen in the path to Shhwonk Fortress in Petal Meadows. This variation is slightly stronger than the Paper Mario variety, since this one has more attack power. The Koopa Troopa is also the first enemy with defense to appear in the game. Koopa Troopas also appear in Hooktail Castle alongside Paratroopas, and rarely in Rogueport Sewers after completing Chapter 5, though here they are only seen inside a battle when confronting a Hammer Bro, Koopatrol, or Magikoopa, again along Paratroopas.

Super Paper Mario
Red and green Koopa Troopas reappear in Super Paper Mario. In this game, they do not have as much HP or Defense as in Paper Mario: The Thousand-Year Door. This time, defeating Koopa Troopas is harder, although one can do it with Boomer, Cudge, or certain items. Even though they only have 1 HP, they duck inside their shells. One can easily be defeated by another's shell.

The good and bad Koopa Troopas introduced in the earlier Paper Mario titles return, but are represented differently: Koopa Troopas under Bowser's control are not the "bad" Koopa Troopas, and some even attempt to save Princess Peach from Count Bleck. However, these "good" Koopa Troopas still attack Mario and his party (in fact, if the player revisits the earlier levels as Bowser, Koopa Troopas without glasses still attack him), as do the Koopa Troopas wearing sunglasses under Nastasia's spell. Their apparent neutrality coincides with the presence of Koopa Troopas wearing red shells and green shells; "bad" Koopa Troopas no longer exclusively have red shells, as green-shelled Koopa Troopas appear as foes wearing sunglasses and spiked collars (similar to Bowser's). They appear in Flipside Pit of 100 Trials in room 11, 14, 16, and 19. A soccer version appears in this game.

Paper Mario: Sticker Star
Koopa Troopas reappear in the Nintendo 3DS game Paper Mario: Sticker Star. These Koopa Troopas no longer wear sunglasses as friendly ones in the game help in battle by damaging enemies, in the form of normal and Shiny Shell stickers. Similar to the previous installations, Koopa Troopas attack by folding into shells and ramming Mario though with more attack power. Using a Tail Sticker will defeat them. In addition to dealing more damage unlike other games, the shell toss attack occasionally inflicts the dizzy status. Koopa Troopas can be beaten in the first strike without engaging in combat with them once the player has obtained six HP-Up Hearts.

Mario encounters some new sub-species of Koopa Troopas, such as the Mural Koopa that depict ancient Koopa Troopas to walk on all fours, similar to the Koopa Troopa's early appearance in the series, and the Shiny Koopa that does more damage and has more defense.

Paper Mario: Color Splash
Green Koopa Troopas and red Koopa Paratroopas appear in Paper Mario: Color Splash as enemies. When a Koopa Paratroopa is jumped on, it loses its wings and becomes a normal red Koopa Troopa. Additionally, three green and three red Koopa Troopas dance in Birdo's concert at Plum Park. Koopa Troopas appear as enemies in Ruddy Road, Cherry Lake, Bloo Bay Beach, The Golden Coliseum, Vortex Island, Lighthouse Island, Fortune Island, and Green Energy Plant. In Dark Bloo Inn, a Koopa Troopa is part of the Shady Sledge Bro's gang, and some Koopa Troopas appear as NPCs in levels such as The Golden Coliseum and the Sunset Express. A variant of Koopa Troopa known as Koopa Troopa 6-Stacks appear in Lighthouse Island and Green Energy Plant.

Koopa Troopas attack by getting into their shells and ramming Mario, doing 7 HP of damage. When a Koopa Troopa is jumped on, it will go into its shell, and if it is attacked again, it will be kicked into the enemies behind it. If there is a wall behind the enemies, the Koopa Troopa will bounce back and hit Mario, even if he summoned it in using an Enemy Card. They will be knocked onto their shells if a POW Block is used.

Super Smash Bros. Melee
Koopa Troopas appear in Super Smash Bros. Melee as enemies in the Mushroom Kingdom stage during Adventure Mode. They may also appear during a regular match by coming out of a Party Ball, though this is uncommon.

Super Smash Bros. Brawl
Koopa Troopas appear as part of Bowser's army in Super Smash Bros. Brawl; Donkey Kong and Diddy Kong face many of them while attempting to get Donkey Kong's Banana Hoard back, and a Koopa is actually the creature that stole the Bananas in the first place (under Bowser's order). Diddy Kong, Fox McCloud, and Falco Lombardi also fight some Koopa Troopas while searching for the kidnapped Donkey Kong. Bowser last uses Koopa Troopas to attack King Dedede's castle in order to steal the trophies that he had amassed. This was the last appearance of Koopa Troopas in the game. Koopa Troopas are not the most common enemies in this game (due to Bowser not being the main antagonist); Primids are actually the most frequently encountered enemies. In all the games where Koopa Troopas appear, their shells can't break, but in a cutscene where the Koopa Troopas steal Donkey Kong's Banana Hoard, it is shown that Donkey Kong can break their shells with his fist.

Super Smash Bros. for Nintendo 3DS
Koopa Troopas appear in Super Smash Bros. for Nintendo 3DS as enemies in Smash Run. They can attack the player by jumping at them, like how they did in Super Smash Bros. Brawl. After being defeated, they will become a shell that can be thrown like an item, but the Koopa Troopa will come back out after short time, even if the shell is still in the player's hand.

Super Smash Bros. Ultimate
A green Koopa Troopa appears as a Novice-type support spirit in Super Smash Bros. Ultimate, taking one slot and equipping the fighter with a Green Shell at the start of a battle when used. In its spirit battle, the player faces Squirtle on the Golden Plains stage. The spirit's core can be used with an Old Man Lobber core and a support core to summon Tortimer's spirit.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga, Bowser takes many Koopa Troopas along with him, Mario, and Luigi inside his Koopa Cruiser when he flies to the Beanbean Kingdom. The crew of the Koopa Cruiser wear unique aviation suits (outfitted in fur and leather bomber hats and jackets) and are called Bowser Baddies in the game. Bowser had planned to do battle with Cackletta, the witch who had stolen Princess Peach's voice, with his army of Koopa Troopas and Goombas (accompanied by the Mario Bros.)—however, the Koopa Cruiser was attacked by Fawful, Cackletta's henchman, before it could reach the Beanbean Kingdom. The Koopa Cruiser, along with all of its Koopa Troopas, crashed just outside the Mushroom Kingdom/Beanbean Kingdom Border, the impact of which knocked all of the Koopa Troopas unconscious. The Koopa Troopas of this game are last seen lying on the ground, although some are already starting to regain consciousness by the time Mario awakens.

During Mario and Luigi's time on the Koopa Cruiser the Koopa Troopas teach them many things, including how to battle. While on the Koopa Cruiser some of Bowser's Goombas started running rampant, and the Koopa Troopas, dubbed the name Bowser Baddies, ask the Mario Bros. to help them control the situation. Although no normal Koopa Troopas can be fought, Beanish variants exist as enemies.

Koopa Troopas also appear in Mario & Luigi: Superstar Saga + Bowser's Minions, were they additionally they appear as enemies and recruitable allies exclusively in Minion Quest: The Search for Bowser. They are melee troopers, and attack by ramming into opponents in their shells. Their special skill, Rock Solid, allows them to increase their defense. Captain Koopa Troopa appears as a usable captain. Koopa Troopas are weak against Dry Bones.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, Koopa Troopas, as in Mario & Luigi: Superstar Saga, are the crew of the Koopa Cruiser and wear similar aviation suits as their past appearance in the series. A reporter named Kylie Koopa also makes an appearance in the game. A sub-species called the Koopeleon also appears in the game.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
As opposed to the past two games, standard Koopa Troopas make an appearance in Mario & Luigi: Bowser's Inside Story. In Blubble Lake, Bowser rescues a group of Koopa Troopas from a cage and is able to use them as a Special Attack called Koopa Corps, where he spins his shell and rebounds Koopa Troopas (which go into their shells) onto enemies. Koopa Troopas are also some of the characters that are seen inhabiting Bowser's Castle.

Red and green Koopa Troopas return in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, where they additionally are found as enemies in the Bowser Jr.'s Journey mode. Both variants are weak to Dry Bones, pink Shy Guys and Spikes, while red Koopa Troopas are strong against all four Para-Biddybud variants. A green Koopa Troopa appears alongside a Scutlet to stop Bowser Jr. and the Koopalings from progressing, only to be defeated and freed from the brainwashing.

Mario & Luigi: Dream Team
In Mario & Luigi: Dream Team, Koopa Troopas make a cameo appearance in Mario and Luigi's fight against Bowser Jr., as part of the audience alongside Shy Guys and Goombas. Kylie also makes a reappearance.

Mario & Luigi: Paper Jam
Koopa Troopas and their paper counterparts appear in Mario & Luigi: Paper Jam as enemies. They appear in Twinsy Tropics, and one is fought alongside a Paper Koopa Troopa in Neo Bowser Castle as one of Bowser's last lines of defense. In battle, Koopa Troopas attack by going into its shell and flinging itself at Mario and Luigi in a circular manner, and if stomped will hit another enemy involved in the battle. They can also attack a single bro, its target being the one it is going in the oppisite direction off, and must be countered with the hammer, at which point it will turn into a Beach Koopa and can get counterattacked repeatedly. This marks the first time in the Mario & Luigi series where actual Koopa Troopas have appeared as enemies, in the previous installments, different species of Koopa Troopas appear: Mario & Luigi: Superstar Saga has Troopeas, Mario & Luigi: Partners in Time has Koopeleons, Mario & Luigi: Bowser's Inside Story has Dark Koopas (in the Dark Bowser battle), and  Mario & Luigi: Dream Team has Dreamy Paratroopas (in the Dreamy Bowser battle).

Mario & Sonic at the Olympic Games
During the opening sequence of the Wii version of Mario & Sonic at the Olympic Games, Koopa Troopas can be seen as cameramen during the Archery and High Jump events, although they are not present in the playable events themselves. Koopa Troopas also appear in the crowds throughout the game.

Mario & Sonic at the Olympic Winter Games
A Koopa Troopa appears as a referee in Mario & Sonic at the Olympic Winter Games.

Yakuman DS
Koopa Troopa is an opponent in Yakuman DS, He frequently melds/declares his tiles and he is a bit harder than Shy Guy and Goomba. His default rank is 16.

Dance Dance Revolution: Mario Mix
In Dance Dance Revolution: Mario Mix they are messing around with Lakitu's farm. They must be stepped on once, then stepped on again to either defeat them or send them down to destroy a step. For this to happen, Mario/Luigi will have to get a perfect step. Once defeated, Lakitu gives Mario/Luigi the Key to the Truffle Towers. They also appear in Mush Mode. Koopa Troopas seem to struggle while on the screen in this game.

Super Princess Peach
Koopa Troopas, just called Koopas, also appear in Super Princess Peach, having the same roles from the Mario platformer games, but with the appearance of those in the Yoshi's Island games. There are four variants: Green Koopas, Mad Green Koopas, Red Koopas, and Glad Red Koopas. Paratroopas also appear with two Vibe variants.

Mario Baseball series
Koopa Troopas appear as team players in Mario Superstar Baseball, along with Mario Super Sluggers. Only two colors are playable, both of them being green and red variants. In both games, the Koopa Troopas has good chemistry with Bowser, Koopa Paratroopa and Dry Bones.

In Mario Superstar Baseball, the green Koopa Troopa is a balanced type player, but its pitching is slightly weak. The Red Koopa Troopa sacrifices some speed to enhance its batting skills.

In Mario Super Sluggers, both Koopa Troopas have good batting and running skills. However, they aren't very good with their pitching and fielding skills.

Puzzle & Dragons: Super Mario Bros. Edition
Koopa Troopas appear in green, red, and yellow varieties in Puzzle & Dragons: Super Mario Bros. Edition.

Green Koopa Troopa
Green Koopa Troopas are Water-attribute enemies. In battle, in addition to attacking normally, they may occasionally use Green Shell to nullify Fire attribute damage for two turns. When defeated, it may randomly drop a Water Block of itself. As Water enemies, they take extra damage from Wood attribute attacks and less from Fire damage.

As teammates, they have an HP rating of 3/6, an ATK rating of 1/6, and a RCV rating of 1/6. Their Green Shell Skill changes any Wood Orbs on the player's Orb field into Water Orbs, while their Awoken Skill Water Boost raises the ATK of any Water attribute teammates when the player clears a horizontal row of Water Orbs. Green Koopa Troopas use Fruits and Rare Fruits to raise their Skill Levels. The player can transform a Green Koopa Troopa into a Green Koopa Paratroopa using two P-Wings, and can be transformed even further into a Big Green Koopa Paratroopa using five Super Mushrooms.

Mario Sports Superstars
Koopa Troopas are playable side characters in Mario Sports Superstars. They are available in soccer and baseball, classified as balance types. The baseball mode features green, red, blue, and yellow colors for Koopas, more than the Mario Baseball series. Soccer, however, only has green and red varieties.

Koopa Troopas are also among the basic enemies encountered in the Road to Superstar game mode.

Dr. Mario World
Koopa Troopas make their debut in the Dr. Mario series in Dr. Mario World. Their Stage Mode skill grants fifty bonus points for each remaining capsule after completing a stage. Their Versus Mode skill grants a four percent chance that the attack meter will instantly fill when the opponent attacks.

Other appearances, cameos, and references
Koopa Troopas were originally written for the 1993 live-action Super Mario Bros. film when it was going to be a fantasy movie, but were cut when it was changed into a science-fiction film. An early script described them as "fierce-looking soldiers, half-human, with turtle-like armored shells on their backs, reptilian facial features and molded armor suits," and have "leathery skin, with turtle-like eyes and mouth." They were also referred to as "Koopa Troopers" in this script. Despite being absent from the film, early production artwork of the film version of Goombas had them labeled with the name "Koopa's Troopas".

In , the guy holding the pizza which the player must deliver to Cleopatra rides a Koopa Troopa.

In the Wii U version of , Koopa Troopas (in red and green) can be spawned.

Koopa Troopas appear in Skylanders: SuperChargers as part of Bowser's moveset; however, due to an agreement between Nintendo and, they are featured exclusively on the Nintendo console versions of the game.

In the Super Mario Mash-Up Pack in Minecraft, Sheep and Turtles are replaced by green Koopa Troopas. A Koopa Troopa also appears as a playable skin, meaning that both bipedal and quadrupedal Koopa Troopas exist in this game.

In Luigi's Mansion: Dark Moon, a Boo named Boopa Troopa is found in Treacherous Mansion's E-2: Double Trouble.

Physical appearance and traits
Koopa Troopas are tortoise-like creatures with removable shells. In general, they have basic appearances compared to other Koopa species. They have elliptical beady eyes, large beak-like noses, short limbs and large heads. Their hands have four pointed/triangular shaped digits and have three pointed toes on their flat-soled feet, which unlike other Koopa species, have no pads at all. In earlier games, Koopa Troopas were quadrupedal (walking on four legs), had flatter noses and detailed leg joints. Starting from Super Mario World onwards, they now stand on two legs, have more rounded noses and wear shoes with beige soles that often match the color of the shells they wear (in the Super Mario Galaxy series, however, they revert back to walking on four legs and have four toes on their back legs). Having beaks, Koopa Troopas have no teeth compared to other species (but may be drawn with them for expression purposes). Although their conceptual ancestor, Shellcreepers, have teeth.

Although most Koopa Troopas are affiliated with Bowser, they seem to be cheerful and friendly creatures intent on doing their job.

Koopa Troopas generally have yellow scales, but in earlier games had orange. Some Koopa Troopas can have olive green, peach and even cyan scales. In Super Mario Strikers, the color of their scales would change depending on with team they were on: salmon for Mario's, chalky yellow for Luigi's, peach for Waluigi's, and orange for Daisy's.

A Koopa Troopa's shell consists of a carapace with colored, hexagon-shaped scutes in a pattern on the top, with smaller, triangular ones at the edges, with dark flesh underneath that appear as "grooves"; a beige colored plaston with several "ribs" on its surface and six holes on it where the Koopa Troopa's head, arms, legs and tail emerge from; all joined by a white bridge that follows along the perimeter of the shell and rises at the spots where the Koopa Troopa's head and tail are. Despite having large heads, Koopa Troopas can pull them into their shells with little effort. Underneath their shells, they wear white undershirts (in Super Mario 64 and its remake Super Mario 64 DS also wear pink or blue shorts, respectively) and have round bodies.

From Super Mario 64 onwards, Koopa Troopas have been given voices created electronically, starting with whooping sounds (which were also shared with Goombas, Big Goombas and King Bob-omb, with varying speeds, until the sounds were exclusive to Koopa Troopas in later games), then other noises such as wheezing, clucking, and gurgling. In Mario Kart 8, they were also given high-pitched whistling sounds whenever performing an antigravity trick or placing first.

Green Koopa Troopas are specifically given an association with water in games such as Mario Power Tennis and Puzzles and Dragons: Super Mario Bros. Edition, since their Offensive and Defensive Power Shots involve water, and their Awoken Skills nullify Fire Orbs. Red Koopa Troopas gain access to fire, yellow gain access to light, and blue gain access to dark.
