[[caption-width-right:256:[[VideoGame/MegaManClassic Bass]] and Koopa Troopas and Goombas from ''[[VideoGame/SuperMarioLand2SixGoldenCoins Super Mario Land 2]]'' in ''VideoGame/SuperMarioBros1''? Yep, [[MassiveMultiplayerCrossover it's that kind of game]].]]

''[[http://www.explodingrabbit.com/games/super-mario-bros-crossover Super Mario Bros. Crossover]]'' (Also known as ''Super Mario Crossover'' due to space limits) is a Flash game by Exploding Rabbit (initially comprised solely of Jay Pavlina, but has expanded to include more people, with Zach Robinson contributing additional graphics to Version 2.0 and Blaine Hanna taking over as the lead developer after Version 3.0). Basically, it's the original ''VideoGame/SuperMarioBros1'' (and ever since a few updates ''[[VideoGame/SuperMarioBrosSpecial Super Mario Bros. Special]]'' and ''VideoGame/SuperMarioBrosTheLostLevels'') but with Mario's brother Luigi having his DivergentCharacterEvolution from the later Mario games, as well as [[{{Contra}} Bill Rizer]], [[{{Metroid}} Samus Aran]], [[VideoGame/MegaManClassic Mega Man]] and his rival [[VideoGame/MegaManAndBass Bass]], [[Franchise/{{Castlevania}} Simon Belmont]], [[VideoGame/TheLegendOfZeldaI Link]], [[VideoGame/NinjaGaiden Ryu Hayabusa]], and [[VideoGame/BlasterMaster Sophia the 3rd]] as additional playable characters, retaining the moves and physics of their source games. There's also [[ArtShift a variety of art styles to choose from]] and [[RemixedLevel alternate level design based on the difficulty]].

Being based on ''VideoGame/SuperMarioBros1'', most of the tropes present there apply here.

Not to be confused with ''VideoGame/MushroomKingdomFusion'', which is a different game entirely.

As of December 16, 2013, the game has been considered done. However, that's not the end of the fun. Back in June 2012, the developers ran a Website/{{Kickstarter}} campaign for ''[[http://www.kickstarter.com/projects/explodingrabbit/super-retro-squad Super Retro Squad]]'' (later renamed ''Super Action Squad''), a SpiritualSuccessor to ''Super Mario Bros. Crossover'' as a tribute to the sixteen-bit generation, and successfully funded the project. They're currently running [[http://www.explodingrabbit.com/forum/pages/super-retro-squad/ another funding campaign]], this time focusing on getting members of the development team to stop their other jobs to accelerate development on the game. This apparently wasn't working out, since the donations weren't as frequent as they'd perfer. [[RealLifeWritesThePlot They're now retooling the game into an]] EpisodicGame.

----
!!This game provides examples of:
* AbandonedInfoPage: As of the end of August 2013, the wiki for the most part is pretty outdated.
* AdobeFlash: And as far as Flash games go, it's a pretty damn good one.
* AscendedGlitch: As of 3.0, it is now possible to jump over the flagpole. There were certain areas in ''Special'' and ''Lost Levels'' that require you to jump over the flagpole in order to reach them.
* AprilFoolsDay: On April 2012, the game was [[http://www.explodingrabbit.com/games/super-mario-bros-crossover/atari updated]] with a skin inspired by the {{Atari 2600}}. However, it also came with a ''massive'' downgrade -- all the other skins were removed, there's only one soundtrack to listen to, the "Single Character Random" game mode is removed, and you can't play as Link, Ryu, Bill, or Samus ([[TheArtifact thus rendering the Classic Samus cheat useless]]). Version 3.0 later added the Atari skins and soundtrack to the official game, including new Atari skins for Link, Ryu, Bill and Samus.
* ArtifactTitle: An inversion! The first iterations of the game didn't have Luigi in it (although, he was planned). Only much later on did he finally make it in, now rendering the ''Super Mario Bros.'' title accurate.
* AudienceParticipation: Most of the skins, features, and characters were all decided by fans. However AuthorAppeal plays a big part in this.
* BagOfSpilling: Whenever the game has a major update, all previous save files are rendered incompatible, thus forcing every player to start over.
* BehindTheBlack: Hard map difficulty is all about mooks waiting beyond the edge of the screen to catch you as you land.
* BigBadEnsemble: Sort of. Bowser is replaced with another antagonist depending on what enemy skin is being used. The ''VideoGame/ZeldaIITheAdventureOfLink'' enemy skin replaces him with Ganon (or if you want to be technical [[VideoGame/TheLegendOfZeldaOracleGames the Great Moblin]]) [[note]] despite Ganon only appearing in the GameOver screen as a silhouette in that game[[/note]], the ''VideoGame/SuperMarioBros2'' enemy skins[[note]] both NES and SNES versions[[/note]] replaces him with Wart, the ''VideoGame/{{Castlevania|I}}'' enemy skin replaces him with Death[[note]]WordOfGod has confirmed that Dracula will not be present, despite being the BigBad and Death being TheDragon[[/note]], and the ''VideoGame/BlasterMaster'' enemy skin replaces him with... [[BuffySpeak some weird monster dude thingy]][[note]] this monster is an original sprite; bosses in ''VideoGame/BlasterMaster'' were not only fought in top-down areas, but they were also gigantic, and due to NES limitations, were as a result fought over a solid black screen[[/note]]. In versions 3.0 and upwards, the ''[[VideoGame/RetroGameChallenge Demon Returns]]'' enemy skin replaces Bowser with... a [[OurVampiresAreDifferent vampiress]].
* BoringButPractical: In earlier versions, GoombaStomp worked quicker than most character's weapons (without a Fire Flower) against most {{mooks}}; 2.0 goes around this aspect by having everyone but the Mario Bros. be unable to stomp. Fortunately, 3.0 features a cheat (which is one of the immediately available ones) that enables everyone else to stomp enemies again. Mario's better jumping tends to make him the easiest character to use, as the stages were designed with him in mind. Among the other characters, the best jumpers are about on par with Mario (though Ryu, Mega Man, and Simon all have ways to deal with their subpar jumping height.) With the timer turned on, Mario and Luigi also help get through the longer levels, being the only characters able to run.
* BossSubtitles: This is how new characters are introduced in the trailers, a la ''VideoGame/SuperSmashBros Brawl''.
* BottomlessPitRescueService: The "Bouncy Pits" cheat, which also affects mushrooms and enemies. It works on all pits, '''including pools of boiling lava'''.
** BonusFeatureFailure: However, the bouncy pits cheat, on the other hand, makes {{Poison Mushroom}}s ''nightmarishly hard to avoid'', as when they bounce off of the bottom of the screen, you can easily end up picking one up and being hurt if it bounces into you. They can also pass straight through platforms as they bounce upwards.
* {{Cap}}: In older versions, the [[ScoringPoints score counter]] maxed out at 999950. The 3.0 update later increased it to 9999999.
* ContinuityNod:
** ''Special'' and the hard/easy maps add a powerup that increases the time you have. This powerup, like most of them, can change appearance depending on what skin you're using. In the ''Super Mario World'' skin, [[http://www.mariowiki.com/Funky_(Super_Mario_World) the powerup is represented by a green berry]].
** World 6-2 in ''Special'' is a PipeMaze, which gets even more intricate on hard difficulty. This references the same level from the original ''VideoGame/SuperMarioBros1'', which was also a pipe maze and is included in the ''Super Mario Bros.'' stages as well.
* CouchGag: The game's StartScreen always loads up a different map skin. Complete with matching skins and interface.
* {{Crossover}}
* DifficultyLevels: As of Version 3.0, there are two types of difficulty settings: Map Difficulty and More Settings. Map Difficulty changes the levels with Easy, Normal, and Hard. More Settings, however, averts this, as it allows you to customize general game behavior.
* DropTheHammer: Courtesy of the Hammer Bros.
** In 3.0, there is a hammer PowerUp, which works similarly to the ones found in DonkeyKong.
* DummiedOut: LOTS of sprites are unused in most of the characters' skins.
** The [[VideoGame/{{Gradius}} Vic Viper]] can be found in a sheet using a flash decompiler.
** Sprites from the original ''VideoGame/FinalFantasyI'' can be found in another sheet the same way.
* DungeonBypass: Link and Samus (through morphball) can quickly beat 3-2 of ''Special'' by going through the small space above the warp pipe, skipping most of the level. Like most if not all shortcuts, this was prevented in the hard mode.
** Ryu Hayabusa's ability to climb walls can help reach the block ceiling of some levels and skip lengthy sections of them. Most notable in Special 6-2 which would otherwise be a PipeMaze. Subverted in some levels after finding out the blocks are unbreakable and the pipe must be reached the normal way.
* DVDCommentary: Jay Pavlina's "[[http://www.youtube.com/watch?v=ZGIIkDkJP3U Playing My Own Game]]" series of videos on Website/YouTube.
* EasierThanEasy: Playing the game with the Map Difficulty set to Easy and setting up the other difficulty settings accordingly.
* EasterEgg: As the character select music of the ''VideoGame/SuperMarioWorld'' skin is the Special World music, [[http://www.youtube.com/watch?v=U2S5s1WtUh0 the Super Mario Bros. theme]] will play if it loops nine times, as it did in ''VideoGame/SuperMarioWorld''.
** Like in VideoGame/SuperMarioLand2SixGoldenCoins, if you get a GameOver as Mario or Luigi in either their [=SML2=] skin or their space suit skin and then [[spoiler:idle on the continue screen for about 3 minutes, [[http://www.youtube.com/watch?v=Js7y-KOO7Gg Totaka's Song]] will play.]]
** World 4-2 of ''Super Mario Bros. Special'' has a hidden warp zone that leads to World ?. [[spoiler:However, this is not an actual world. Going inside the warp pipe brings the player to a BonusStage called the "Exploding Rabbit Room" (according to the Exploding Rabbit Wiki). In this room, the words "Exploding Rabbit" are spelled out in coins, along with a few hidden boxes. It is also currently the only level that has the Exploding Rabbit PowerUp, hidden in a block, which gives the current character all his/her power-up (for Samus, Ryu, Simon, and Bill, it will give him or her a random PowerUp). However, this also counts as an AscendedGlitch, as this pipe was also present in ''Special''. Although it originally just had the player wait until time ran out if entered, as the pipe didn't go anywhere.]]
* FakeDifficulty: The Bullet Bill cannons fire at ''erratic'' intervals.
* FanRemake
* FollowTheMoney: On the easy maps, if there is a single coin floating in the air by itself, chances are that there is an InvisibleBlock just underneath it.
* GenreBusting: Some characters' original games were ''not'' platformers, but were adapted to the platform genre.
** Link, being from a [[TheLegendOfZelda top-view adventure game]], was given physics to match those of ZeldaIITheAdventureOfLink.
** SOPHIA III and Samus, both games being the {{Metroidvania}} genre, were both adapted to a more "point A to point B" style of play.
** Ryu and Bill were both adapted to platforming as opposed to the "Run and Gun" style of their original games.
* HarderThanHard: Playing the game with the Map Difficulty set to Hard and setting up the other difficulty settings accordingly. [[SarcasmMode Have fun dying]].
* InvincibleMinorMook:
** In the difficulty settings, you can replace the Goombas with Spike Tops. They can still be killed off by Star Power or Samus' Missles, though.
** ''Special'' (and the hard maps) adds Barrels and Fires from the original ''Donkey Kong''. The former actually acts much like Spike Tops (in fact the ''Super Mario Bros 3'' skins replace them with what seems like bulkier Spike Tops) and can still be killed by misiles, however the Fires are almost completely invincible.
* [[TheDevTeamThinksOfEverything Jay Pavlina Thinks Of Everything]]:
** In underground levels that have access to Warp Zones, the block right next to the pipe that takes you to the normal path is indestructible in order to at least have a way to play through the game normally, even as characters that easily destroy blocks.
** The map skins have a "corresponding" character skin, such as Mario's sprite from ''Super Mario World'' in the map skin of the same game. This map turns World 7 into a [[BigBoosHaunt ghost house,]] and if you play as SMW Mario with this on, the Ghost House theme plays. But this would seem odd if you used another skin, since World 7 by default isn't ghost-themed, right? Well, simply playing on it with another graphic skin causes the regular "ground" theme to play instead.
** Normally, there's only one music per character used as a castle theme. However, when using the ''Zelda II'' map skin, if you have the music options set to "Map", the final level plays the Great Palace theme instead of the normal Palace theme.
* JumpPhysics: Even though the stages are all designed with Mario's jump in mind, all characters retain theirs.
* KonamiCode: How you can quickly unlock cheats in Version 3.0 onwards[[labelnote:*]]Originally, you need to enable and disable the "Classic Simon" cheat five times, followed by the press of the Special Button. By the way, the "attack" and "jump" buttons take the place of B and A, not the actual B and A keys.[[/labelnote]]. The title screen fanfare from ''Contra'' plays when you select "Enter Code" in the Cheats menu as a hint for which ClassicCheatCode you need to use.
* {{Main/Leitmotif}}: Each character skin comes with the musical score from their original game, although it can be set to match the map skin, a certain game's score or just randomized.
* MarathonLevel: World 8-1 is still as long as it was in the original, which means a lot of trouble for every character but the Mario Bros., as they're the only ones who can run. Fortunately, unlocking the "Infinite Time" cheat is as easy as completing the first level, providing an easy way to escape the dreaded time limit if you don't want to {{speedrun}} with the other characters in this level.
* MassiveMultiplayerCrossover
* MediumBlending: Depending on how you set the graphic options and the character skin.
* MusicalNod: The Atari skin uses many songs from different Atari 2600 games (although some of them are just {{chiptune}}s).
* MusicalSpoiler: When selecting the "Enter Code" option on the Cheats menu, the music changes to the title theme from ''VideoGame/{{Contra}}''. [[spoiler:It's the KonamiCode]].
* NintendoHard: It can be hard for the other characters to adapt to some of the harder Super Mario Bros levels.
** In the 2.0 update, all characters [[BagOfSpilling lose their power ups and abilities]] upon taking damage, except on Very Easy. And then [[OneHitPointWonder there's Bill]]...
** Also, the 3.1 update includes levels from ''Super Mario Bros. 2''. [[VideoGame/SuperMarioBrosTheLostLevels And that's the Japanese one, by the way]]. If you thought those levels are [[PlatformHell already as hard as they are]] as Mario and Luigi, then try playing through those levels as everyone else -- or even better, playing through them with the Map Difficulty set to Hard...
** Speaking of the hard maps, one might expect the game to start out with only mild and minor changes to add a little more challenge, slowly curving into something much harder. Nope, on the ''first level'' of the SMB set there's a Lakitu at the first half, Paratroopas positioned in akward places over pits, and an ending staircase where every other block column is a tiny bottomless pit, and every other column out of what remains is a Bullet Bill cannon.
*** And that bonus room that serves as a shortcut to the end of the level? It now exits into ''the pipe before the entry pipe to said bonus room''.
*** Remember the first Super Mushroom of Super Mario Bros? Inside that arrangement of 6 blocks ingrained forever into the collective gamer mind? [[DamnYouMuscleMemory Well,]] in Hard Map difficulty, it's a PoisonMushroom now.[[note]]The actual Super Mushroom is on the top block[[/note]]
* ObligatorySwearing: Not ingame per self, but while playing, two videos are displayed at the side of the game, and the description on one of the videos may have a swear word in it. Fortunately, this can be somewhat avoided by playing the game in fullscreen mode.
* PoisonMushroom: The TropeNamer shows up in ''The Lost Levels'' as usual, but it also shows up in the Hard Maps for the other two sets.
* PowerCreepPowerSeep: Used and averted. Each character's weapons are greatly {{nerf}}ed, but characters do retain their jump physics.
* ProductPlacement: {{Downplayed|Trope}}. Mario and Luigi's "Modern" skins say that the skins are designed after ''VideoGame/SuperMario3DWorld'' (although the "Modern Mario" skin is more reminiscent of the Mario sprite used in ''VideoGame/PaperMarioTheThousandYearDoor'')
** Also, the first loading screen advises players to support the official game releases.
* RatchetScrolling: Removed by default, though it can be turned on in the Cheats menu (listed as "Classic Screen Scroll", which is available from the beginning).
* RemakeCameo: The Hudson Bee (also known as the "Hu-Bee") is a PowerUp in ''Special'', although it changes depending on the skin.
* {{Main/Retraux}}: The Atari skins for most characters and the Atari map layout. The choice of musical score turns it into hilarious StylisticSuck.
* SaveThePrincess: While originally you were always saving Toads and Peach like in the original game, the 2.1 update changes them to characters appropriate to each playable character.
* ScheduleSlip: The V3.0 update -- featuring even more skins (including the AprilFoolsDay Atari skin), additional cheats, refined difficulty settings (including {{Remixed Level}} maps based on difficulty) and the ''Super Mario Bros. Special'' levels -- was initially announced for the end of June 2013, but it was delayed for the end of July instead.
* SchrodingersPlayerCharacter: The Toad inside each castle and Princess Peach turn into characters/objects from the game the current player character belongs to, and the "YourPrincessIsInAnotherCastle" response changes accordingly. Even if the new Toad or Princess are characters the player can control at any given moment.
* SerendipityWritesThePlot: The ''VideoGame/SuperMarioBrosTheLostLevels'' map set is modelled after the levels used in ''[[VideoGameRemake Super Mario Bros. Deluxe]]'' since the developers had no time to add new code to the characters, such as being pushed by wind. This fits well, since the ''Super Mario Bros. Deluxe'' versions of the levels were specifically modified to use the same physics as the original game.
* ShoutOut: The character select screen from version 2.0 onwards resembles that of the ones found in the SuperSmashBros series.
** In 2.1 and onwards, Luigi's Peach skin has her saving [[SuperPrincessPeach Mario]].
* SillinessSwitch: There's an "Invisible" skin that gives the game the appearance of the original game, but with all possible ground, platforms and footholds removed in addition to enemies. There's also a cheat to replace all enemies with Hammer Bros. Finally, you could set all possible options to random[[labelnote:*]]that would be "Music Console" and "Music Set" under "Sound Options", and "Map Skin", "Enemy Skin", and "Interface Skin" under "Graphics Options"[[/labelnote]] and play "Single Character Random" mode. Each time you play this way is essentially a new adventure.
* SoundtrackDissonance: In either the [[http://www.explodingrabbit.com/games/super-mario-bros-crossover/atari Atari version]] of the game or when using the Atari map skins and characters in the latest version, the music that plays whenever you encounter Bowser is... [[spoiler:"Fever" from ''VideoGame/DrMario'']]?
* SpeedRun: In the ''VideoGame/SuperMarioBros1'' map set, the same shortcut route ([[spoiler:(1-1)-(1-2)-(Warp Zone to World 4)-(4-1)-(4-2)-(Warp Zone to World 8)-(8-1)-(8-2)-(8-3)-(8-4)]]) works as well.
* TimedMission: Like in the original, levels have time limits by default, but it can be turned off with a very easily unlockable cheat (just beat a level).
* TrollingCreator: There was a vote to see if either ''VideoGame/SuperMarioBrosTheLostLevels'' or ''VideoGame/SuperMarioBrosSpecial'' would be added to 3.0. Even though ''Lost Levels'' won, Jay Pavlina did ''Special'' instead; since he had more interest in doing so (he wanted a more obscure set of levels to use).
* TurnsRed: The Sidestepper enemies in the ''Special'' maps[[note]] as well as in the other map sets on Hard Mode[[/note]] become angry and double in speed as they lose health.
* VideoGameDemake: The Atari 2600 skin is an in-universe example.
* VideoGameSettings: Several map skins gives themes to the worlds, which were otherwise rather plain in the original game. The Super Mario Bros 3 skins, specifically, gives each world its own theme as seen in ''VideoGame/SuperMarioBros3'' itself.
* WhatCouldHaveBeen: Originally planned to have an ExcusePlot of Luigi gathering others to help him rescue Mario.
** [[http://www.gamexplain.com/article-64-1272509580-super-mario-bros-crossover-xplained-an-interview-with-the-creator.html According to a GameXplain interview]], Ryu, Sophia, and Luigi were all planned to be in the game from the beginning, but they were cut from the first release due to time and have since been reinstated into the game as of 2.0. Radd Spencer from ''VideoGame/BionicCommando'' was also under consideration.
** The game was planned to be ported to the Unity engine, but the port (as well as its planned multiplayer mode) was cancelled so that Jay could concentrate on ''Super Retro Squad''. However, there will still be further updates to ''SMBC'', including the aforementioned skin and level additions.
** The [[http://www.youtube.com/watch?v=lE1K9yNDNA8 v2.0 trailer]] showed that in addition to the Game Boy filter, there could have been filters based on [[http://tcrf.net/CGB_Bootstrap_ROM the Game Boy Color bootstrap ROM]] and [[http://tcrf.net/Super_Game_Boy_1_and_2 Super Game Boy]]. The trailer at one point also shows the Game Boy filter applied to the background, but not to the player or the enemies.
* TheWikiRule: [[http://www.explodingrabbit.com/wiki/Super_Mario_Bros._Crossover SMBC has its own section on the Exploding Rabbit Wiki.]]

!!Character Tropes:
* BroughtDownToNormal: Inverted. When v1.1 came around, [[GameBreaker Bill]] was the only character (besides [[JackOfAllStats Mario]]) not to get some sort of gameplay improvement.
* ChargedAttack: Mega Man's Mega Buster and (prior to v2.0) Ryu's Windmill Shuriken.
* DivergentCharacterEvolution: Certain skins (such as Quick Man, Proto Man, and Pit) play differently than their parent character, essentially making them new characters built on the same base.
* DoubleJump:
** Simon has one to compensate for his short and awkward jump. Comes out of nowhere ([[VideoGame/CastlevaniaRondoOfBlood Maria]] and later {{Metroidvania}} player characters would have a double jump, but Simon wouldn't have it until ''[[VideoGame/CastlevaniaHarmonyOfDespair Harmony of Despair]]'', which was released after this game).
** Bass also has a double jump ability, that is unless his Quick Man skin is used.
* GoombaStomp: As of 2.0, only Mario and Luigi can do this without getting hurt.
** Link can do this with a downward thrust.
** 3.0 introduces a cheat that allows everybody to do this.
* GoKartingWithBowser: The 2.0 update included three playable villian characters: [[VideoGame/MetroidPrime Dark Samus]], [[VideoGame/ZeldaIITheAdventureOfLink Dark Link]], and [[VideoGame/MegaManClassic Dr. Wily]], as skins for Samus, Link, and Bass, retrospectively. You can also play as six Robot Masters [[note]][[VideoGame/MegaMan1 Cut Man, Ice Man and Fire Man]] (all three for Mega Man), [[VideoGame/MegaMan2 Quick Man,]] [[VideoGame/MegaMan3 Gemini Man]] and [[VideoGame/MegaMan4 Skull Man]] (all three for Bass)[[/note]].
* MovesetClone: Mario and Luigi share similar abilities. Mega Man and Bass also share the same weapons as each other except their default busters and Rush Coil.
* OneHitPointWonder: Bill has become this in the 2.0 update. No matter what difficulty is being played or what powerups he has, he will always die in one hit.
** Everyone becomes this on Very Hard difficulty.
* PrecisionGuidedBoomerang: Link's special weapon.
** Ryu's Windmill Shuriken can stretch one's WillingSuspensionOfDisbelief: No matter how long you keep dodging it, it will keep attempting to come back to you.
* SelfImposedChallenge: Arguably Simon's entire purpose. Except the odd underwater stage where [[ThisLooksLikeAJobForAquaman the angle of his axes deals with the highly annoying bloopers perfectly]]. [[DifficultButAwesome On the other hand,]] his axes also have a wider arc than the [[DemonicSpiders Hammer Bros']] hammers. Plus there's his [[WhipItGood whip]], which eventually becomes super-long and [[IncendiaryExponent flaming]]. And as of v1.1, an option exists that lets you control his jumps more easily.
** These days it's a "classic Simon" option in which having it off makes it easier to control his jumps.
* SwordBeam: Link's Fire Flower ability.
** In later versions, it's tied to the red ring power up.
* UnderwearOfPower: Getting a Fire Flower as Samus changes her sprite to the "Justin Bailey" power-suit-less version, along with upgrading her weapon to the Wave Beam... Well, that was in an earlier version. Now, it's averted, as she gains her Power Suit when she gets a Super Mushroom (and the Justin Bailey suit is, as of 2.0, a skin).
* UnexpectedCharacter:
** [[VideoGame/RetroGameChallenge Robot Ninja Haggle Man]] of all things is in Version 2.0, as a skin for Ryu. The "Demon Returns" game from ''Game Center CX 2'' also provides both level graphics and a pair of skins for Mario.
** ''Dr. Wily himself'' is a skin for Bass, making him [[GoKartingWithBowser one of the first three playable villain characters in the game, alongside Dark Samus and Dark Link]].
*** Wily himself also gets two skins based on [[MegaMan6 Mr. X]] and two more skins based on Quick Man.
** Toad and Peach as skins for Mario and Luigi respectively. Similarly, [[VideoGame/KidIcarus Pit]] can replace Samus, Roll and VideoGame/RokkoChan can replace Mega Man, and Zelda, the Old Man, and the heroes of the BSX Zelda remake can replace Link.
** A "T" tetrimino from ''VideoGame/{{Tetris}}'' is a skin for Sophia.
** Shadow from ''Videogame/FinalFantasyVI'' is a skin for Ryu. He comes with some ''Franchise/FinalFantasy'' tracks (mostly from his own game).
** [[VideoGame/MegaMan1 Cut Man, Ice Man and Fire Man]] serve as skins for Mega Man, while [[VideoGame/MegaMan2 Quick Man]], [[VideoGame/MegaMan3 Gemini Man]] and [[VideoGame/MegaMan4 Skull Man]] serve as skins for Bass. Some of these skins even differ from Mega Man and Bass:
*** Cut Man's projectiles pass through blocks and enemies.
*** Ice Man's uncharged shots do less damage, but his charged shots can freeze enemies like Samus' Ice Beam.
*** Fire Man is immune to the rotating firebars, but receives more knockback from enemy attacks.
*** Quick Man has a different movement pattern[[note]]He moves faster and jumps higher but he can't do Bass's double jump or dash maneuvers[[/note]].
** 3.0 Brings us [[VideoGame/FinalFantasyMysticQuest Benjamin]] as a skin for Link, complete with his game's music (including awesome boss theme). He isn't functionally different from Link at all.
* WalkDontSwim: Only Mario, Luigi and Sophia the 3rd can swim. Everyone else has this trope applied to them, giving you a whole new challenge tackling the water levels.
* WallCrawl: Ryu and Sophia can cling to walls, just like in their original games. (And ceilings, in Sophia's case.) However, as of 2.0, Sophia needs to find a power-up to do this.
* WhipItGood: Simon.
