Bowser's Castle (or simply Bowser Castle) is a recurring location in the Mario franchise. It is the domicile of the Koopa villain Bowser and the base of operations for his army. The castle's name, design and greater location vary from game to game, but the castle is usually situated in a volcanic world and is characteristically an important base from which the Koopa King formulates his plans and summons his minions to take over the Mushroom Kingdom and carry out the capture of Princess Peach. Bowser's Castle is usually the final area that Mario and his friends visit to defeat Bowser and rescue Peach and is usually guarded by Bowser's most powerful minions. In the Mario spin-offs, the castle can serve as a go-kart course, a tennis court, a baseball stadium, etc., depending on the sport the game is based on.
Super Mario series
Super Mario Bros. / Super Mario Bros.: The Lost Levels
Bowser's Castle first appears in Super Mario Bros. at the end of World 8. In the level 8-3, Mario battles Bowser's forces outside of the castle, which can be seen in the background; in World 8-4, Mario ventures into the castle itself, where he battles and defeats Bowser in order to save Princess Peach. It is similar in Super Mario Bros.: The Lost Levels, except that it appears in world D-3 and D-4 instead, while a castle located in the sky is found in World 8-4. In Super Mario All-Stars, Bowser's Castle is easily distinguished from the other castles by having thunder and lightning flash in the background.
Super Mario Bros. 3
In Super Mario Bros. 3, Bowser's stronghold (as well as Bowser himself) is not seen until the very end of his kingdom, Dark Land (which is also called "Bowser's Castle" in later remakes). The mentioned castle itself is one of the longest levels in the game and is where Bowser is keeping Princess Peach captive. The map icon is animated in Super Mario Advance 4: Super Mario Bros. 3. It is also the only actual castle level in the game.
Super Mario World
In Super Mario World, Bowser's Castle is found in the Valley of Bowser. There are two ways of entering the castle and many ways to reach the end of the level. There are two main corridors where Mario or Luigi will have to choose one of four possible doors. The player can also reach the Castle by using the Star Road that leads them to the front gate, bypassing the rest of the Valley of Bowser entirely. To get to the back gate, the player had to find the secondary exit in Valley of Bowser 2 and go through Valley Fortress. This takes the player straight to Back Door, skipping most of the level. The castle itself featured a neon sign with Bowser's name spelled out. Bowser is also seen flying in the background of the castle in his Koopa Clown Car, albeit in silhouette during occasional thunderclaps and his eyes glowing in the darkness otherwise. In Super Mario Advance 2, he is absent entirely after the level is cleared.
New Super Mario Bros.
In New Super Mario Bros., Bowser's Castle is relatively similar in appearance to the one in Super Mario World. It is found rising out of a lake of lava and is at the end of a twelve-level-long path. Once inside, Mario/Luigi will encounter Thwomps, Dry Bones, Rocket Engines, as well as Lava Bubbles. The ? Switches in the castle have an unusual effect; once pressed, the gravity of the castle will invert and the Player, along with any enemies (excluding Rocket Engines) will have their positions inverted. The second part of the castle is a looping room, similar to Worlds 4-4 and 7-4 of Super Mario Bros., with lots of lava, a single Lava Bubble and a single Fire Bar. Once the final boss door is reached at the castle's end, the Player will have to battle both Bowser Jr. and Bowser.
New Super Mario Bros. Wii
Bowser is again fought in his castle in New Super Mario Bros. Wii. After clearing the final airship level for the first time, the characters reunite with Princess Peach before Kamek takes her to Bowser's Castle, which was hidden behind a rock wall in the northern part of World 8, the wall then recedes, revealing the castle, Bowser's evil laugh is heard as Kamek swoops down into the castle with Peach. The characters go through three parts: The first is a normal side-scrolling area with lava, Lava Bubbles and Fire Bars. The second part is a vertical area with draining lava which auto-scrolls downwards, more Fire Bars and some Dry Bones trying to stop Mario. The third is Bowser's lair. In the final battle, Kamek casts a spell to make Bowser grow massive and he chases Mario and the rest of the characters through his castle.
Later after the final battle, when six of the Koopalings flip Bowser on his belly, the castle starts falling down on top of them.
Super Mario 3D Land
Bowser has two castles in Super Mario 3D Land, both located in World 8. The first castle is the World 8 Castle, its appearance is similar to castles of previous titles, as well as previous castle levels in the game. At the end of the castle Mario fights Bowser and defeats him by pressing the switch at the end of the bridge, causing Bowser to sink in the lava below. Mario makes his way to Peach (which can previously be seen in the level using a pair of binoculars), only to discover that it is just a cardboard cutout. Bowser then appears with the real Peach in hand and flees to his larger castle, which is the true Bowser's Castle.
The real Bowser's Castle differs from previous castle levels, as Mario spends much of it riding Bonecoasters. Mario then reaches a cannon which launches him to a tower with another cannon on it, which Mario uses to reach Bowser's tower. No Checkpoint Flags are found in this level. Mario then walks to the big red door and enters. Peach is tied up to the flagpole, but before Mario can rescue her, Bowser falls from above and attempts to crush Mario, which causes the floor to collapse and the final battle begins. Bowser attacks Mario with fireballs, spiked balls and barrels as Mario makes his way up the castle until they reach the second bridge. Mario tricks Bowser into clearing the path to the switch, which Mario presses, causing the bridge to collapse and Bowser to fall. However, as Mario continues to make his way up the castle, Bowser returns and pursues Mario, breathing purple flames which jet towards Mario, until they reach the final bridge, in which Bowser chases Mario until Mario reaches the final switch, which he presses, once again causing the bridge to explode, sending Bowser falling into the lava. Mario then rescues Peach and they head back home.
After completing the Special Worlds, Bowser kidnaps Peach again and Mario must return to his castle to defeat him and save Peach once again.
New Super Mario Bros. 2
Bowser's Castle reappears in World 6 of New Super Mario Bros. 2. Like in New Super Mario Bros. Wii, Mario and Luigi face Bowser twice at the end of the castle. Its appearance in this game is again similar to that of New Super Mario Bros.
New Super Mario Bros. U
Although Bowser's Castle itself does not appear in New Super Mario Bros. U, Bowser after capturing Peach's Castle in the beginning of the game starts renovating the castle to better resemble his own castle, ultimately succeeding by the time Mario fights Bowser Jr. for the final time.
Super Mario 3D World
In Super Mario 3D World, Bowser's Castle reappears as World Castle, the seventh world of the game. The castle appears to be floating high above the Sprixie Kingdom, the game's setting. A second castle appears as World Bowser, the game's final world, themed after an amusement park.
Super Mario Maker / Super Mario Maker For Nintendo 3DS
In Super Mario Maker, Bowser's Castle appears in the 10 Mario Challenges and the 100 Mario Challenges.
Super Mario Odyssey
In Super Mario Odyssey, Bowser's Castle is located in Bowser's Kingdom. Unlike in most games, in which it has a Western design, it is a traditional Japanese castle, with a concentric series of walls and baileys, a traditional garden and tea house, and a central keep. Instead of the usual lava, its moats are filled with poison.
Super Mario Maker 2
The Super Mario Bros. Super Show!
In The Super Mario Bros. Super Show!, King Koopa owns a wide range of castles, ranging from fortresses, towers and even an ice palace; most often at the end of an episode, the featured castle of King Koopa would be destroyed and if not, would likely not be seen again. Unlike the games, the various castles seen in The Super Mario Bros. Super Show! lack the abundance of traps that would normally appear in a castle owned by Bowser.
The Adventures of Super Mario Bros. 3
The Adventures of Super Mario Bros. 3 migrates away from the concept of King Koopa owning several castles and, instead, he only owns one castle, located in Dark Land. This castle is interchangeably referred by the names "Kastle Koopa" and "Koopa Kastle". Kastle Koopa largely resembles its game counterpart, with Bowser's image engraved on it, though it is blue in color and lacks towers. Kastle Koopa also possesses a large hall filled with portraits, as well as bedrooms for the Koopalings and a laboratory most often used by Kooky von Koopa.
Super Mario World television series
In the Super Mario World cartoon produced by DIC Entertainment and Nintendo, the main base and home for Bowser and the Koopalings is called King Koopa's Neon Castle. Apparently located in a lava filled wasteland, Neon Castle lacks the amount of towers its game counterpart possesses, only having one; Neon Castle also possesses a rectangular shape and, like the Japanese version of the game, has "KOOPA" flashing in neon lights on its front, instead of "BOWSER". The castle carries over many of its game counterpart's traps, like Ball 'N' Chains, lava, fire-breathing statues and various kinds of minions. In the episode Mama Luigi, Mario refers to it as Bowser's "Coney Island Disco Palace", a name most likely based off of the final section of Bowser's Castle in that game, which featured a disco ball that illuminated it.
Mario is Missing! / Mario's Time Machine
Bowser's Castle is the main setting of the game Mario is Missing!, but instead of being located in the Koopa Kingdom, like in the other games, this castle is located in Antarctica. The castle is also the main setting for the game Mario's Time Machine, specifically as the location of Bowser's Museum.
Super Mario Adventures
In Super Mario Adventures, Bowser's Castle is only seen near the end of the comic and is portrayed as a large fortress, having many spike-covered towers and a large great hall, capable of holding several hundred different creatures. Catacombs and a lava filled chamber inhabited by Blarggs are also depicted in this version of Bowser's Castle.
Mario Kart series
Bowser's Castle has appeared in every Mario Kart game to date. In Super Mario Kart, there is a different course of the castle in every Cup except the Special Cup. Bowser Castle 1 appears in the Mushroom Cup, Bowser Castle 2 appears in the Flower Cup and Bowser Castle 3 in the Star Cup. Mario Kart: Super Circuit features all of the courses from Super Mario Kart, so they appear in that game as well, and the Paper Mario castle makes a cameo appearance in the Rainbow Road track. Mario Kart 64 features a Bowser's Castle course in the Star Cup. In 50cc mode, there is one Thwomp, in 100cc mode, there are two and in 150cc and Extra modes, there are three Thwomps right before turn 4. Mario Kart: Super Circuit has its own Bowser's Castle courses, but it also has a fourth one. Mario Kart: Double Dash!! and the later games of the series have a Bowser Castle course in the Special Cup. It also features Bowser Castle 2 from Mario Kart: Super Circuit (Banana Cup section) in Mario Kart DS, the same Bowser Castle from Mario Kart 64 (Lightning Cup) and Bowser Castle 3 from Mario Kart: Super Circuit (Leaf Cup section) in Mario Kart Wii and Bowser Castle 1 from Mario Kart: Super Circuit (Shell Cup section) in Mario Kart 7 as the retro courses. Every version of the course features the same dangers: lava, Thwomps (with the exception of Mario Kart 8) and dangerous jumps. In Mario Kart 8 and Mario Kart 8 Deluxe, the track features an anti-gravity section which goes around a giant lava Bowser, who occasionally slams a fist onto one of the tracks, blocking racers. It is also the first course to not feature Thwomps.
Super Mario World 2: Yoshi's Island
In Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3, Bowser's Castle is located atop a tall mountain on the island. The last level takes place here and it requires the player to go into one of four random doors. Afterward, a giant playroom for Baby Bowser is discovered inside. After defeating Baby Bowser, Kamek will come by and make him extremely large. The player fights on the top of the castle which, throughout the battle, is slowly destroyed. The castle is later entirely destroyed after the final battle.
In Yoshi's Story, Baby Bowser's Castle is split into four different areas: Mecha Castle, Lift Castle, Ghost Castle and Magma Castle. No matter what part of the castle Yoshi decides to go to, he will always meet up with Baby Bowser. The outside of the castle will also be seen whenever one of the Yoshis gets defeated, captured and brought to the castle, along with when White Shy Guy retrieves one. It is also seen in the ending sequence when Baby Bowser's minions carry him away.
Yoshi's Island DS
In Yoshi's Island DS, Bowser travels back to the past searching for the seven Star Children so he could rule the universe. He takes over the castle of his younger self. After Baby Bowser is defeated, Bowser himself is faced. When he is defeated the first time, Kamek makes Bowser gigantic and destroys the castle in the battle.
Yoshi's New Island
In Yoshi's New Island, Yoshi ventures to Bowser's Castle to save Baby Luigi and the Stork from the clutches of Bowser. Throughout the level, Yoshi must collect four keys to reach Baby Bowser. The final boss fight is very similar to that of previous games; Yoshi must throw three eggs at him to proceed. In the second phase, however, Baby Bowser grows giant and attacks from the background, requiring Yoshi to throw Mega Eggdozers at him. Once he takes three hits, Yoshi rescues Baby Luigi and the Stork, and the Mario Bros. are delivered to their house.
If the player has completed every level in the game without using Flutter Wings or Golden Flutter Wings (excluding special levels), Bowser will travel back in time to serve as the true final boss of the game. During the first phase of the battle, Bowser will attack by rearranging the ground and blowing fire at Yoshi. To defeat him, the player must hit him with Metal Eggdozers three times. The second phase of the battle is nearly identical to the second phase of Baby Bowser's battle; however, this time Kamek will cast spells at Yoshi. Once the player throws three Mega Eggdozers at him, Bowser returns to his own time, and Yoshi saves Baby Luigi and the Stork once and for all.
Yoshi's Woolly World / Poochy & Yoshi's Woolly World
In Yoshi's Woolly World and Poochy & Yoshi's Woolly World, Yoshi chases after Kamek to Bowser's Castle to save his fellow Yoshis. Once he enters the castle, he must seek yarn balls of four different colors to open the door to Baby Bowser. The first phase of the boss fight is very similar to that of previous games. Yoshi must throw a yarn ball at Baby Bowser, stomp him, and repeat the process two more times to proceed. In the second phase, Baby Bowser grows giant and becomes Mega Baby Bowser. He jumps into the background and hurls big yarn balls at Yoshi. To win, Yoshi must throw these big yarn balls back at Mega Baby Bowser. Upon victory, the player unlocks eight new Yoshi colors, as well as Baby Bowser Yoshi if all five Wonder Wool in the level were collected.
Yoshi's Crafted World
Super Mario RPG: Legend of the Seven Stars
During the events of Super Mario RPG: Legend of the Seven Stars, the castle is named "Bowser's Keep" and is isolated on a mountain of red, jagged rocks. The keep rests on the largest rock, which, in fact, resembles Bowser himself. The castle can only be accessed by a long bridge that connects to the faraway Vista Hill. The halls of Bowser's Keep are lined with statues of Hammer Brothers and Bowser. The castle is originally guarded by Terrapin soldiers. Additionally, molten lava flows through the keep in several areas. Fortunately, several bridges allow access across the lava. Unfortunately, the bridges are wooden and as such, will eventually collapse in a room filled with lava. In fact, one bridge breaks right after Mario walks across it. Later, this bridge is replaced with hovering Donut Blocks. The castle is also filled with ornate chandeliers. Mario and Bowser actually duel on the top of these chandeliers.
Bowser's Keep is also the Smithy Gang's base of operations in Mario's world. During the beginning of Smithy's invasion, the gigantic sword Exor crashes into the keep. Since Exor is the gateway to Smithy's dimension, the soldiers of the Smithy Gang have an easy time taking control of the castle. In fact, many of Bowser's soldiers defect or run away instead of fighting. Eventually, the Smithy Gang claims the castle as their own. Additionally, Exor destroys the bridge connecting Bowser's Keep to the outside world. As such, the castle can only be accessed by flying vehicles.
Before the fight against Magikoopa, there will be 6 doors to choose from, though only four doors are required. There are two action courses, two battle courses and two puzzle courses.
Paper Mario series
In Paper Mario, a new Bowser's Castle is secretly built right underneath Peach's Castle and Bowser lifts it into the sky, kidnapping Princess Peach, along with her castle. The power used to lift the whole castle into the sky is the Star Spirits' and the Star Rod's power, both of which Bowser had stolen from Star Haven. Bowser also jails the Toad Minister and other nine Toads, a Dryite and a Bumpty who failed to escape during Princess Peach's party. There are two Toad Houses (made from the slate in the prison), a shop run by a Spiked Goomba, Storehouse and three Guard Doors. In the end, Mario manages to take back the Star Rod as well as save Princess Peach and her castle. Bowser's Castle, meanwhile, ended up destroyed alongside the nearby Power Platform, the latter due to it undergoing a meltdown due to the intensity of Mario and Bowser's fight. In this game, Bowser's Castle looks bigger than Peach's.
In-game map descriptions
Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, Bowser's Castle does not play a major role, as only the outside and a hallway are seen. Its appearance is mainly to show Kammy Koopa explaining to Bowser what happened to the Princess.
Super Paper Mario
In Super Paper Mario, the castle has an equally minimal role, as it is where Count Bleck kidnaps the entire Koopa Clan and Tippi takes Mario to Flipside. This is the exact same castle seen in Paper Mario: The Thousand-Year Door. However, in The Bitlands, Bowser found a set of several smaller castles, where several of his minions were located. After Mario destroyed them and defeated the Koopa King, the Princess convinced him to join them on their quest.
Paper Mario: Sticker Star
Like in the first Paper Mario, Bowser's castle is the final area in Paper Mario: Sticker Star. It was initially disguised as a cliffhead. However, after Mario collected all of the Royal Stickers, he managed to reveal via paperization the true form of the cliff. Nonetheless, Bowser had his castle levitated to the sky as a means to deter Mario's advance on it shortly thereafter, although he nonetheless managed to arrive there via a Flutter that Mario befriended. Mario later fought and vanquished Kamek in this castle and later defeated Bowser (who was currently using the sixth Royal Sticker after he accidentially obtained it).
Paper Mario: Color Splash
Bowser's Castle, called Black Bowser's Castle in-game, appears as the final area in Paper Mario: Color Splash. It is built on a floating island with an appearance similar to that of Bowser's Sky Castle, but with warp pipes leading into the rock.
The castle's entry hall consist of a hallway where Princess Peach's portrait is initially seen, just out of reach. When Mario attempts to lower it, however, a trapdoor opens leading to a confrontation with Roy Koopa. A door in the pit leads to a factory where all the paint stolen from Prism Island is brought to mix into black paint. The black paint is then used to color weapons such as Banzai Bills and Bob-ombs, which Black Bowser intends to use to paint the world black. Mario manages to destroy the tank holding the black paint which floods the factory. The factory also has a warp pipe leading back to the entry hall.
Behind the wall where Peach's portrait was is a hallway leading to Bowser's throne room, with the princess now hanging above the throne. After Black Bowser is defeated, the castle begins to collapse, due to the black paint. Mario, Luigi, and Peach escape while Huey stays behind and, to ensure the black paint does not fall into the ocean, squeezes the castle, removing the black paint and transforming it into a card.
In battle, the Black Bowser's Castle card summons the castle and crashes it into the opponents. It is also powerful enough to instantly defeat Black Bowser in battle.
Mario & Luigi series
Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga and its 3DS remake Mario & Luigi: Superstar Saga + Bowser's Minions, Bowletta goes back to the Mushroom Kingdom so she can use Bowser's Castle to attack the Beanbean Kingdom after being tricked into capturing Luigi disguised as Princess Peach, which allows him to retrieve the stolen Beanstar from the repaired Koopa Cruiser. In this game, the castle is in the sky, can breathe fire, and resembles Bowser. Towers act as the castle's "hands", and around the castle's "torso" are cannons and an opening. This flying castle design is reused in Yoshi's Island DS.
The castle acts as the final area of the game; Mario and Luigi fly there with Blablanadon near the end of the game to stop Bowletta after the latter hears about the castle attacking the Beanbean Kingdom and Prince Peasley being sent to stop it. The map of the game hides the castle throughout the majority of the game with a folded upper-left corner until it attacks Beanbean Castle Town; in the remake, the corner is not folded, and when Bowletta launches her attack, a picture of the castle is taped onto the map instead. Within the castle, the Mario Bros. must battle many of Bowser's troops and fight each of the Koopalings (some with Time Bob-ombs on their side) in their respective rooms in order to progress further, until they make it to Fawful.
After defeating Fawful, the Mario Bros. make it into the throne room where Bowletta resides. Bowletta reveals she will not only conquer the Beanbean Kingdom, but the Mushroom Kingdom as well, and attacks the Mario Bros. They fight and seemingly defeat Bowletta after a long battle, but a Time Bob-omb suddenly appears and knocks them out, and she then swallows the brothers. Inside her body, the Bros. must fight and defeat Cackletta's spirit; after they defeat her, they are ejected out of Bowletta's body before she is turned back into Bowser and Cackletta's spirit perishes. The Mario Bros., Peasley and Blablanadon then escape the castle before it blows up, courtesy of a time bomb planted by Prince Peasley. Bowser regains consciousness and begins wondering what he has been doing the whole time, only for the castle to explode moments later and send him careening into the camera. The castle's remains crash into Oho Ocean in the original game, while it simply explodes and disappears in the remake; Bowser is fortunately saved by Prince Peasley.
The "main" grounded Bowser's Castle appears in the credits, when the Toad Express drops the present containing Bowser through its roof.
Bordering or connecting locations to Bowser's Castle include:
Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, the Mario Bros. visit Baby Bowser's castle in the past, after the Koopa Cruiser crashes into the castle upon being shot down by the Shroobs. Though the quartet are initially split up, they eventually reunite there and start their adventure together. Baby Bowser himself is never seen inside the castle during the entire game, though the Mario Bros. discover a Cobalt Shard that he is keeping inside a chest. There is also a time hole there which links to Peach's Castle in the present. Oddly, the castle on the map in the present looks the exact same as the one in the past and still depicts Baby Bowser.
Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
In Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, the castle, here labeled as "Bowser Castle", is taken over by Fawful, with Midbus taking control of operations. After Bowser helps fire a Banzai Bill at his hijacked castle from Dimble Wood, Midbus commands the castle to elevate, dodging the Banzai Bill, and then lands it on top of Bowser. Mario and Luigi must travel to Bowser's Rump Command and cause Bowser to grow big enough to fight his castle.
In battle, the Castle's main attack is a flying ram, which Bowser must counter by punching. Its main tactic is opening its entrance doors and releasing Spinies, which prevent Bowser from punching. After the castle is defeated, Midbus retreats and the castle is returned to its original location. Later, as Bowser attempts to enter the castle, Midbus commands it to hover out of Bowser's reach. After wandering to the opposite side of the area, Midbus fires a giant cannonball at Bowser, who Mario and Luigi must help by building up energy in his arms. With their assistance, he throws it back at the castle, damaging it badly enough to force it to land. Bowser then gains access to the castle, where he discovers that Fawful has not only brainwashed his minions, but had also turned the castle into a theater. In the meantime, Bowser decides to see the show Fawful puts on. A Goomba acting under the orders of Fawful tricked him into sitting in a VIP chair, which fires Bowser onto the stage and forces him into a fight against Midbus.
After Bowser beats Midbus, Bowser is forced to eat a "victory feast" that Boos feed him. This causes him to become so fat that he gets stuck in the floor. After a strange hand grabs Princess Peach, Bowser falls through the floor and lands on a treadmill, where he manages to lose the excess weight. He is then blasted out by exploding Bob-Ombs and sent into the Tunnel.
Later in the game, Bowser must return here to look for the second Star Cure, which he had stolen before the events of the game. Fawful has blocked the path to his treasure stash, and Bowser must push a Fawful statue off the castle balcony to break the barrier. However, his brainwashed minions begin to push against the statue too, trying to save the statue and push Bowser off the balcony, forcing the Mario Bros. to assist him and provide extra leg strength once more. Bowser finally makes it to his treasure vault with the assistance of some Monty Moles, only for them to betray him and reveal that they turning the tunnel into a railway for the Fawful Express.
After battling the Fawful Express, Bowser return to the Treasure Chamber to obtain the Star Cure from the safe. After recalling the combination with Mario, Luigi and Starlow's help, Bowser opens the safe and grabs the Star Cure. However, his minions Private Goomp, Corporal Paraplonk and Sergeant Guy then push him into the safe and trap him in it, announcing their betrayal and defection to Fawful. The safe is then moved eventually to Peach's Castle.
Curiously, the castle has a cold-storage vault, in which a large part of the Shroob invasion force from the events of Partners in Time is kept frozen, along with their princesses, who somehow survived their defeat. If Mario and Luigi find the password required to enter this room, they can fight three of the Shroobs (which they inadvertently defrost) as optional bosses. According to Bowser Jr.'s Journey, the cold-storage vault was originally created by Kamek to store the Ever Ice as a means to preserve it, despite its permanent nature, in the event that Bowser Jr. needed it - which he ultimately did thanks to the Blorbs outbreak at Bowser's kingdom.
During the credits, Bowser's minions are repairing the damages done to the castle. After being beaten by Mario and Luigi back at Peach's Castle, Bowser is carried back to his castle, and a Magikoopa treats him while he is bedridden. Birdley and Starlow arrive at the castle to deliver a present for him; a cake from Princess Peach. Before Bowser opens it, Starlow chats with him for a bit, and re-accepts Private Goomp, Corporal Paraplonk and Sergeant Guy back into his troop once they apologize for their betrayal, telling them to work on the repairs of his castle.
In the remake, the castle is labeled as "Bowser's Castle" and in the main game plays the same role as the original. There are no major changes in the rematch in the remake's Challenge Node, other than the fact that the Shy Guy-manned airships move faster and fire faster cannonballs more rapidly. In the Bowser Jr.'s Journey mode, it is revealed that after Fawful took over Peach's Castle, his treasonous minions the Best Fitness Friends took control of Bowser's Castle for themselves. In this mode, the castle's basement is labeled as the Lava Lair, which Bowser Jr., Kamek and Morton explore after the Castle had taken off for Dimble Wood. Additionally, Bowser's Castle is the final area for Bowser Jr.'s Journey. In the post game, due to Bowser challenging Bowser Jr. to a personal battle and neither one admitting defeat, the castle's repairs ended up undone.
Mario & Luigi: Dream Team
While Bowser's Castle does not appear in Mario & Luigi: Dream Team, a new castle conjured from the Dream Stone is created during the events of the game, and serves as the stronghold for Bowser and Antasma on Pi'illo Island. At the end of the game, this castle is destroyed due to the Dream Stone being shattered after Antasma and then Bowser are defeated.
Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, Bowser's Castle appears as an area located near Doop Doop Dunes. The castle can also be seen off in the distance at several points in the game. The castle also has a cannon built into the roof, which Bowser uses to destroy the bridge connecting his castle to Doop Doop Dunes as well as knock out Mario, Luigi and Paper Mario.
The castle is first seen during the first cutscene containing Bowser, where after some disagreements, he and his paper counterpart decide to team up. They then kidnap their respective Princess Peaches and return to the castle. The castle's next appearance is in Doop Doop Dunes, where upon entering the area, the Mario Bros. and Paper Mario spot Bowser's Castle in the distance, which they must cross the desert to reach. As they come close, the Bowsers notice and decide to blast the gang with cannonballs. The first shot misses them, but destroys the bridge connecting the castle to the desert, while the second shot knocks them all out cold. Wendy, Roy, Larry and Ludwig then arrive to take them to the Twinsy Tropics Dungeon, while the Bowser Jr. duo collects the book containing Paper Mario's world.
Much later in the game, the group reaches Bowser's Castle in order to rescue the princesses and get the book back. They learn the Trio Glider before encountering the two Kameks and Papercraft King Boo, who is controlled by Morton and Lemmy. Toadette also arrives just in time with a Papercraft Yoshi to fight the Papercraft King Boo. After the victory, Kamek kidnaps Toadette to bring the production of papercrafts to a stop, then prepares to build Papercraft Bowser. The gang later rescues Toadette before encountering the Bowser Juniors on guard duty.
The Princess Peaches then escape and greet the team, but are caught by the Bowser Juniors. They mean to fight, but after accidentally revealing they possessed the book the Bros. are after (which they did not know they had), the pair flee. The group eventually catches them and forces them to hand over the book, but the Juniors escape after giving them a decoy book. The gang chases them down and engages in a battle with them, defeating them. Before they can get the book back, the two Bowsers enter the room, enraged at their sons' defeat. They then activate "the boosters", lifting Bowser's Castle out of the lava moat and dubbin it "Neo Bowser Castle". The gang escapes, forgetting the book, and the Bowsers retaliate for their sons' defeat by firing on Peach's Castle and ravaging it. The castle is presumably returned to ground level after the Bowsers' defeat.
Unlike other Mario & Luigi games, the castle's design is based on the Mario platformers and lacks the Bowser head and "arm towers" of the previous designs. Additionally, Bowser's Castle is located at the edge of a desert instead of a volcanic wasteland, although a giant lava moat is built around the castle. Additionally, this design does not have a stone head of Bowser anywhere, but instead has a green Bowser-like emblem logo in the center. Further reflecting on the designs of canon incarnations, the castle sports a large number of spiked green domes that resemble Bowser's shell.
After Bowser's Castle becomes Neo Bowser Castle, its original location at the end of Doop Doop Dunes can no longer be explored, even when the game is completed.
Mario Party series
Bowser's Castle makes infrequent appearances in the Mario Party series. The minigame Bowser's Lovely Lift in Mario Party 7 takes place in the castle, although only the tower holding the lift is seen. Several cutscenes in the story mode of Mario Party DS take place in Bowser's Castle. It is where Bowser's Pinball Machine is located and the final boss minigame, Bowser's Block Party, takes place in the throne room of the castle. Chaos Castle from Mario Party 10 takes place within the castle: The first part of the board takes place on the exterior, the second part takes place inside the castle with a factory theme before ending in the throne room. The Bowser Board in amiibo Party is also based on the castle. World 4 of Mario Party Star Rush is based on Bowser's Castle.
Super Smash Bros. series
Super Smash Bros. for Nintendo 3DS
In Super Smash Bros. for Nintendo 3DS, a stage based on Bowser's Sky Castle from Paper Mario: Sticker Star appears in the Paper Mario stage. At certain intervals, the castle's eyes may light up and the castle entrance (modeled after Bowser's head) may turn or close its mouth, heavily damaging any character inside.
Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, the Molten Fortress sub-area in the World of Light adventure mode is modeled after Bowser's Castle. Paper Mario also returns and Bowser's Sky Castle appears in the same role it did in the previous game.
Mario Pinball Land
In Mario Pinball Land, Bowser's Castle appears as the final area, being called the Fiery Stage by the manual. It is only accessible after Mario has defeated all the other bosses and collected at least 15 stars. The bosses can all be found and battled in the castle once more. Bowser must also be battled and defeated here in order to beat the game.
Super Princess Peach
As Super Princess Peach takes place on Vibe Island, rather than the Mushroom Kingdom, the castle itself is not seen during the events of the game. However, Bowser built a villa there, which is considered to be another castle.
