'''Red Shells''' (also formatted as '''red shells''') are objects introduced in ''[[Super Mario Bros.]]''. They are red [[Koopa Shell]]s that often home in on targets when thrown, unlike [[Green Shell]]s.
==History==
===''Super Mario'' series===
====''Super Mario World''====
Red Shells are objects in ''[[Super Mario World]]''. This is the first game where Red Shells were given properties different from those of other shell colors. A Red Shell can be eaten by [[Yoshi]] to have him spit out three fireballs instead of the shell, though a [[Yoshi (species)|Red Yoshi]] can use this for any shell color. Also, all Koopa shells can appear by themselves, including the Red Shell; stomping a red Koopa Troopa out of its shell renders it a red [[unshelled Koopa]]. A red or green unshelled Koopa that enters a Red Shell becomes a red Koopa Troopa.

Once [[Fall]] is unlocked by beating [[Funky (level)|Funky]] in the original game, or by [[completion|clearing all 96 exits]] in ''[[Super Mario World: Super Mario Advance 2]]'', all Red Shells become red-colored [[Mario]] [[Luigi|Bros.]] masks but otherwise function the same; many instances of Red Shells and Koopa Troopas are also replaced with [[Blue Shell]]s and Blue Mask Koopas, though red variants of each can still be found.

====''Super Mario Galaxy''====
Red Shells are objects in ''[[Super Mario Galaxy]]'' and its [[Nintendo Switch]] [[Super Mario Galaxy (Nintendo Switch)|port]]. They can be held by Mario and thrown, in which case the Red Shell will home in on any nearby enemies. Underwater, a held Red Shell allows Mario to swim faster than a Green Shell. [[Coin Shell|Gold Shell]]s also appear in this game, functioning like Red Shells when thrown.

===''Mario Kart'' series===
{{multiframe|[[File:SMKRedShell.png]]|size=150|align=left|Item roulette sprite of a Red Shell from ''[[Super Mario Kart]]''}}
[[File:MKW Red Shell Artwork.png|thumb|140px|The Red Shell, as it appears in ''[[Mario Kart Wii]]'']]
Red Shells (or '''Torpedo Shells''')<ref>{{cite|date=April 1997|title=''Nintendo Magazine System'' (AU) Issue #49|publisher=Catalyst Publishing|language=en-au|page=39}}</ref> are items in the ''[[Mario Kart]]'' series as one of six items that are present in every installment. They first appear in ''[[Super Mario Kart]]'', and have the ability to home in on the opponent in front of the user.

Red Shells can also appear in [[Triple Red Shells|sets of three]] as well, and are usually a player-exclusive item, though they can be stolen by opponents using a [[Boo]]. When Triple Red Shells are used, three Red Shells rotate around the driver's [[kart]] upon usage, and they can protect them from [[Banana]]s and other items (except in ''[[Mario Kart: Double Dash!!]]''). If a driver collides with another driver while using Triple Red Shells, the other driver is hit by one of the shells; if both drivers have a set of [[Triple Green Shells]] or Triple Red Shells, both are lost.

In ''Super Mario Kart'', Red Shells travel straight towards the racer in front of the user, homing in on them without following the road. Unlike Green Shells, they cannot be dropped behind the user and must be thrown forward.

In ''[[Mario Kart 64]]'', single Red Shells are obtainable from first to fifth place. Like in ''Super Mario Kart'', Red Shells can be thrown only forward in this game, but they now follow the road to hit the target racer. However, Red Shells get destroyed if they hit any walls or the like. In this game only, [[Fake Item Box]]es can be used to block incoming Red Shells.

In ''[[Mario Kart: Super Circuit]]'', single Red Shells can be laid behind the player and act as a land mine, chasing after the first kart that passes by, even the user.

In ''Mario Kart: Double Dash!!'', the Triple Red Shells are a [[Special Item (Mario Kart series)|Special item]] exclusive to [[Koopa Troopa]] and [[Koopa Paratroopa|Paratroopa]] (and [[Petey Piranha]] and [[King Boo]], who can obtain any special item). Also, in ''Double Dash!!'', the three shells are carried in their hands rather than circling around the kart. When the kart is hit by an item, they are left with a single shell. Starting with this game, Red Shells emit a constant sound effect; in this case, a siren-like sound.

In ''[[Mario Kart DS]]'', Red Shells may hit the target kart from the side, which prevents any items behind the kart from blocking it. Single Red Shells are obtainable from 2nd to 6th place; Triple Red Shells are excluded from the [[Nintendo Wi-Fi Connection|Wi-Fi]] mode, as items cannot be equipped in that mode.

In ''[[Mario Kart Wii]]'', Red Shells can also hit racers from the sides, and are obtainable from 1st to 8th place; if the player they were targeting was hit by something else, they will slow down until the player is vulnerable so they can hit properly. The best chance of getting this item is in 2nd place, with a 25 percent (10 out of 40) chance of getting it in said position.

In ''[[Mario Kart 7]]'', Red Shells are able to trail in the sky and enter launcher passages (such as Barrel Cannons) to pursue flying racers; in previous games, Shells would simply fall when thrown in the air, and disappeared when they entered launching areas. Red Shells are obtainable from 1st to 5th place; Triple Red Shells are still player-only items, but the AI can use them if the "Shells Only" item setting is enabled.

In ''[[Mario Kart 8]]'' and ''[[Mario Kart 8 Deluxe]]'', they retain their properties from ''Mario Kart 7''. In ''Mario Kart 8 Deluxe'', they can now appear for AI racers as well; Red Shells also travel somewhat slower when they lock onto their target, allowing players to outrun them in 200cc when they have a speed boost.

In ''[[Mario Kart Tour]]'', Red Shells appear as an item, with only the single variant available. The following gliders in the game increase the chance of getting Red Shells and points for hitting racers with one.

!width=60%|Gliders
{{:Special skill (Mario Kart Tour)|transcludesection=Red Shell}}
|}

In ''[[Mario Kart World]]'', Red Shells can be dodged by using a [[Feather]] at the right time. Shells also make an 8-bit sound effect when they hit someone.

===''Mario Tennis'' series===
Red Shells are items in the [[Mario Tennis (Nintendo 64)|Nintendo 64 version]] of ''Mario Tennis'' and ''[[Mario Power Tennis]]'', where they can be used during an Item Battle match and obtained by hitting an [[Item Box]] with the ball over the net. If the player hits the ball after receiving the item, a Red Shell comes out and chases the opponent.

In ''[[Mario Tennis Open]]'', a Red Shell is the emblem for the Shell Cup and appears on its trophy. A full tennis uniform-and-racket set with a design based on this item is available for [[Mii]]s to use.

===''Super Smash Bros.'' series===
Red Shells are items in ''[[Super Smash Bros.]]'' and ''[[Super Smash Bros. Melee]]''. Unlike the Green Shell, which moves in a straight path, the Red Shell will "attach" to the platform it lands on, spinning back and forth and targeting nearby fighters (including the user) before disappearing after a short time.

Red-shelled Koopa Troopas and Paratroopas appear in [[smashwiki:Adventure Mode (SSBM)|Adventure Mode]] in ''Super Smash Bros. Melee'', [[smashwiki:Adventure Mode: The Subspace Emissary|The Subspace Emissary]] in ''[[Super Smash Bros. Brawl]]'', and [[smashwiki:Smash Run|Smash Run]] in ''[[Super Smash Bros. for Nintendo 3DS]]'', and will retreat into their shells if hit enough; however, their shells function the same as Green Shells when thrown.

===''Mario & Luigi'' series===

}}
====''Mario & Luigi: Partners in Time''====
The Red Shell is a [[Bros. Item]] in ''[[Mario & Luigi: Partners in Time]]''. The brother that chooses the item will kick the Shell towards a foe; once it hits them and bounces off, it will slide towards the other bro, who must press their corresponding button to kick it back. Like the Green Shell Bros. Item, the Red Shell can be kicked back repeatedly, and moves faster with each kick. Unlike the Green Shell, it will automatically target a new enemy if one is defeated; it can also land more than 16 hits, and can be kicked indefinitely until one of the brothers misses or all enemies are defeated.

When the adult and baby Mario brothers fight together, the babies can sit on the shell; pressing their button upon hitting the enemy will perform a spin that increases damage for each hit.

====''Mario & Luigi: Dream Team''====
[[File:MLDT - BrosAttack 1 RedShell.png|thumb|left|3D Red Shell in ''Mario & Luigi: Dream Team'']]
The Red Shell reappears as the first of Mario's [[Bros. Attack]]s in ''[[Mario & Luigi: Dream Team]]'', under the name '''3D Red Shell'''. It costs 4 [[Bros. Point|BP]] to use. The [[Attack Piece]]s to obtain the 3D Red Shell are found in [[Mushrise Park]], and are required to proceed through the game. It can only target enemies on the ground like its counterpart, the [[3D Green Shell]], but will automatically target a new enemy if the targeted one is defeated.

Upon selecting the attack, Mario and Luigi will run into the foreground, where Mario will take out a Red Shell. Pressing {{button|3ds|A}} has him kick it at one of the enemies; after it hits and rebounds, the player must then press {{button|3ds|B}} to have Luigi kick it back, and alternate between them for each kick. After the Red Shell hits nine times, Luigi will then spin the Red Shell towards Mario to blast it at their foe for the tenth and final hit; if all enemies are defeated before the attack ends, it will end prematurely.

Striking three, five, nine and ten times with the Red Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.
{{br|left}}

====''Mario & Luigi: Paper Jam''====
[[File:MLPJ 3DRedShell.png|thumb|left|3D Red Shell in ''Mario & Luigi: Paper Jam'']]
The Red Shell returns in ''[[Mario & Luigi: Paper Jam]]'' (again under the name 3D Red Shell), functioning the same as it did in ''Mario & Luigi: Dream Team''. However, the move is now available from the beginning of the game, costs 3 BP instead of 4, and deals considerably more damages at the cost of being shortened to six hits. The speed of both the shell and the Bros. moving forward is also increased.

Striking one, three, five and six times with the Red Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.
{{br|left}}

====''Mario & Luigi: Brothership''====
Mario is again able to use this attack in ''[[Mario & Luigi: Brothership]]'', with the BP cost being reverted to 4. It is received alongside the Green Shell on [[Shipshape Island]] after defeating [[Gorumbla]].

Instead of kicking the shell toward the enemy, Mario and Luigi quickly trade the shell with alternating {{button|switch|a}} and {{button|switch|b}} inputs as they build up its power, culminating in Mario kicking the shell into one enemy, dealing heavy damage to it. The attack, unlike its previous iterations, can hit an airborne target.

Striking three, five, seven and nine times with the Red Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.

===''Mario Strikers'' series===
[[File:Strikers Red Shell.png|thumb|Red Shell icon in ''Super Mario Strikers'']]
Red Shells are items in the ''[[Mario Strikers]]'' series. They are obtainable in groups of three, similarly to the ''Mario Kart'' games; red [[big shell|Giant Shell]]s also appear. When thrown, Red Shells home in on a nearby opponent instead of sliding in a given direction; shells that miss their target will bounce around the stage like a Green Shell. A red Giant Shell will home in on a target to flatten, bouncing around the stage as normal after. Red Shells are generally useful when clearing room for a  [[Super Strike]], a [[Mega Strike]], or a [[Skillshot]].
===''Mario Hoops 3-on-3''===
Red Shells appear as defensive items found in [[? Panel]]s in ''[[Mario Hoops 3-on-3]]''. When thrown, they home in on the player currently holding the ball. They have less accuracy than in the ''Mario Kart'' series, and if they miss their target, the Red Shell will then act like a Green Shell and simply bounce off the boundaries of the court.

===''Mario & Sonic'' series===
====''Mario & Sonic at the Olympic Games''====
Red Shells appear during the [[Dream Race (Mario & Sonic at the Olympic Games for Nintendo DS)|Dream Race]] event in the [[Nintendo DS]] version of ''[[Mario & Sonic at the Olympic Games (Nintendo DS)|Mario & Sonic at the Olympic Games]]''. The shells function similarly to those in the ''Mario Kart'' series, homing in on an opponent and causing them to lose speed if they are hit, but a [[Barrier (Sonic the Hedgehog)|Shield]] can be used to block their effects. The shells also appear in [[Dream Long Jump (Mario & Sonic at the Olympic Games)|Dream Long Jump]], where they also cause the player to lose height, though they can be blocked by using a Shield or [[Super Star|Starman]]. They appear in the [[Dream Canoe]] event with a similar function; the player who manages to hit another competitor with a Red Shell steals three of their coins. They come in sets of three, and can be avoided or blocked by using a Starman item. 

Red Shells perform an almost identical function during the [[Dream Race (Mario & Sonic at the Olympic Games for Wii)|Dream Race]] in the Wii [[Mario & Sonic at the Olympic Games (Wii)|version]], where they can be thrown forward and home in on opponents, causing them to lose speed when hit; they can be dodged using a Starman, invincibility from a [[Chaos Emerald]] or by jumping over them. Red Shells also appear as items in [[Dream Platform]], where they will home in on an opponent and destroy any [[Brick Block]]s between it and the target, and can be blocked by using a [[Barrier (Sonic the Hedgehog)|Barrier]].

====''Mario & Sonic at the Olympic Winter Games''====
In the Nintendo DS version of ''[[Mario & Sonic at the Olympic Winter Games (Nintendo DS)|Mario & Sonic at the Olympic Winter Games]]'', Red Shells are homing items in [[Ski Cross Racing]], [[Rocket Ski Jumping]] and [[Extreme Snowboarding]], where they can be thrown forwards or backwards, though they can be blocked using a Barrier or Super Star. In Rocket Ski Jumping, besides causing their target to lose speed, a Red Shell also causes them to lose height and energy.

Red Shells are homing items in the [[Mario & Sonic at the Olympic Winter Games (Wii)|Wii version]], appearing in [[Dream Alpine (Individual)|Dream Alpine]], [[Dream Ski Cross (Individual)|Dream Ski Cross]], [[Dream Snowboard Cross (Individual)|Dream Snowboard Cross]], [[Dream Short Track]], the [[Dream Gliding (Individual)|Individual]] and [[Dream Gliding (Team)|Team]] versions of Dream Gliding, the Individual version of [[Dream Ski Jumping (Individual)|Dream Ski Jumping]], and [[Dream Bobsleigh]]. Players can use Shields or Super Stars to defend against them. In the Individual version of Dream Ski Jumping, Red Shells will cause an opponent to lose height, speed, 10 points and a [[Bonus panel]], but a Barrier can defend against them. In [[Dream Curling]], the item turns the curling stone into a Red Shell that homes in on the pins until coming to a standstill.

====''Mario & Sonic at the London 2012 Olympic Games''====
Red Shells are items in the [[Mario & Sonic at the London 2012 Olympic Games (Wii)|Wii version]] of ''Mario & Sonic at the London 2012 Olympic Games'', particularly within several London Party minigames, while in the [[Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|Nintendo 3DS version]], the Red Shell and Green Shell appear together on a [[List of badges in Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|badge]] that can be obtained from the badge machine.

====''Mario & Sonic at the Sochi 2014 Olympic Winter Games''====
Red Shells appear in [[Snow Day Street Hockey]] in ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]'', where [[Pianta]]s will occasionally swap the puck for one if it is shot into their box. Red Shells move faster and bounce further than the standard puck, but not as much as the Green Shells.

====''Mario & Sonic at the Rio 2016 Olympic Games''====
Red Shells are homing items in the [[Wii U]] [[Mario & Sonic at the Rio 2016 Olympic Games|version]] of ''Mario & Sonic at the Rio 2016 Olympic Games''. Hitting an opponent with them will add 10 Duel Points to the player's supply, and the player can also hit the parade float with them, which will cause the [[Octus]]es to shoot energy balls at the opposing team that also award the player Duel Points.

====''Mario & Sonic at the Olympic Games Tokyo 2020''====
Red Shells are items in the [[Dream Racing]] event of ''[[Mario & Sonic at the Olympic Games Tokyo 2020]]'', where they home in on the nearest opponent, like in the ''Mario Kart'' series, but do so while hovering above the ground slightly. The opponent drops several of their [[Ring (Sonic the Hedgehog)|Rings]] when hit.

===''Mario Sports Mix''===
Red Shells are items in ''[[Mario Sports Mix]]''. They can chase after an opponent and knock out anyone in the path, and combining a Red Shell with a ball or puck can make it travel at a higher speed.

===Other appearances===
In ''[[Monopoly Gamer]]'', a Red Shell face is on the "Power-Up Die". A player who rolls the Red Shell normally can force any other player on the board to drop three Coins on their current space, which can be picked up by the next player who passes over or lands on that space. Some characters have a "Power-Up Boost" that enhances or changes this power.

In ''{{iw|nookipedia|Animal Crossing: New Leaf}}'', [[nookipedia:Item:Triple Red Shells|Triple Red Shells]] appear as special furniture that can be obtained randomly from fortune cookies. When interacted with, they continuously play the Red Shell alarm from ''[[Mario Kart DS]]''. In ''{{iw|nookipedia|Animal Crossing: Pocket Camp}}'', a single Red Shell can be obtained as a reward for catching five [[Eep Cheep]]s in Fishing Tourney #12, which began on March 14, 2019 as part of the ''Super Mario'' crossover event for [[MAR10 Day]]. In ''{{iw|nookipedia|Animal Crossing: New Horizons}}'', the [[nookipedia:Item:Shell (New Horizons)|shell]] furniture item can be customized to its "red" variant, either by using one [[nookipedia:Item:Customization Kit (New Horizons)|customization kit]] or paying 1,000 bells to {{iw|nookipedia|Cyrus}} on {{iw|nookipedia|Harv's Island}} to customize the item.
