''Mushroom Kingdom Fusion'' is a (as yet unfinished: v0.53) non-profit fan-made platforming video game that is based on ''Franchise/SuperMarioBros'' It is a CrossOver with elements, characters, and settings from a multitude of other video games.

The game consists of mechanics primarily from the SNES and GameBoyAdvance renditions of ''VideoGame/SuperMarioBros2'', ''VideoGame/SuperMarioBros3'', and ''VideoGame/SuperMarioWorld''. Enemy characters include standard Mario-universe enemies, demonic beings, alien creatures, and human soldiers. The music includes the usual Mario series music, along with tracks from the ''Franchise/{{Halo}}'' series and other games featured in ''MKF''. The game features items from the Mario series and weaponry originally used by the Covenant races in ''Halo'', in addition to suit items that bestow upon the main playable characters the guise and abilities of certain characters from the ''VideoGame/MegaMan'' universe.

Characters featured in ''MKF'' include Mario, Luigi, and Wario plus a roster of characters from other video game franchises (such as ''SonicTheHedgehog'', ''Franchise/TheLegendOfZelda'', ''NinjaGaiden'', and ''VideoGame/MegaMan'').

The game design is influenced by franchises such as the ''Sonic'', ''VideoGame/{{Doom}}'', and ''Mega Man'' series and other Nintendo titles. Other game franchises featured include (but are not limited to) ''MetalSlug'', ''Franchise/{{Castlevania}}'', and ''VideoGame/GhostsNGoblins''; some obscure game titles represented are ''{{R-Type}}'' and ''EVOSearchForEden''.

[=JudgeSpear=], the game's founding developer, stepped down from the project due to increasingly polarized views of the game's content and the inclusion of many different game elements, far removing the game from the original concept of just Mario visiting other game worlds, plus several disagreements with the other team members. A spinoff fangame project, ''SuperMarioFusionRevival'', was founded to revive that original concept.

As of October 20th, 2013, [[http://fusionfangaming.spriters-resource.com/site-news-board/is-this-game-cancelled/?PHPSESSID=0caade31f1737a86ccb4ea5273054f30 the game was cancelled]], but the developers [[http://fusionfangaming.spriters-resource.com/site-news-board/the-current-and-final-plans-for-mkf/ have since decided to]] WrapItUp.

Can be found [[http://fusionfangaming.spriters-resource.com/ here.]] Their Website/YouTube channel is [[http://www.youtube.com/user/MKFusionTeam?feature=watch here]] for those who want a free look at what they have accomplished so far.
----
!!This game provides examples of:
* AbortedArc: The SHMUPS Domain (World 6) was axed due to the SHMUP engine being stuck in DevelopmentHell. The completed and planned platforming SHMUP-themed levels were moved to World 9, while World 6 became a fantasy-themed world.
* AcceptableBreaksFromCanon: The game's developers don't really take minor things in continuities into account [[RuleOfFun so the game can be more entertaining]]. For instance, Sonic can use a rifle [[ShadowTheHedgehog despite previously saying he would never be caught dead with one]].
* AcidTripDimension: The Minus World, by virtue of representing games that don't fit into the other worlds.
* {{Acrofatic}}: Wario.
* ActionGirl: [[{{Metroid}} Samus Aran]] will be in this game. Any questions?
* AdvancingWallOfDoom: Taken to its logical extreme with its "RUN" sections in some levels, where the screen moves as fast as your character's running speed.
* AllThereInTheManual: Most of the game's plot is this at the moment, as the game has yet to implement a majority of the cutscenes that will be in the story. The best places to read up on it (if you don't mind spoilers) are the Wiki and the forums.
* AmbidextrousSprite:
** Halo Suit Mario swinging the Energy Sword.
** The buster in the ''Mega Man'' Suits.
** Link swinging his weapon.
** Roll's Buster.
* ArtisticLicenseBiology: Granted, this is a given for {{Womb Level}}s, but why are there villi in the Behemoth's ''esophagus''? (Because EverythingIsTryingToKillYou. '''Everything.''')
** The Loggerhead sea turtle [[http://www.vetmed.ufl.edu/college/departments/sacs/research/seaturtletechniques/esophagus.htm has backward-facing spines in its esophagus]] to prevent its usual prey (jellyfish) from escaping. They probably could've thought of it that way instead of villi (structures in the small intestine).
* AscendedMeme: The list so far...
** When Tails uses the Tanooki Suit, his statue is the Tails Doll.
** Whenever Wario enters the stage with the Guts Man Suit, he teleports in and immediately stops to pose while the "Gut Man's ass" fanfare plays.
** Eggman, upon catching Solid Snake in his lair, pulls out the infamous "[[AdventuresOfSonicTheHedgehog Snooping as usual, I see!]]" line.
** Waluigi's victory pose when clearing a level in his Striker powerup is a crotch chop. He also dons Captain Falcon's suit to perform the [[MegatonPunch Falcon Punch]] and Falcon Kick.
** Morshu from VideoGame/TheLegendOfZeldaCDiGames functions as the shopkeeper.
** Air Man gets a more difficult boss battle due to his "No One Can Defeat Air Man" song, with an instrumental version of said song playing for the fight.
* AuthorAppeal: The now-defunct World 6 idea, SHMUPS Domain, along with the SHMUPS mechanic. [=JudgeSpear=] himself said the only reason why a whole ''world'' devoted to one genre was planned for the project was because he was a big fan of it.
** It may also explain why all the general (non level/world-specific) boss themes come from games in said genre.
* BaitAndSwitchBoss: After you fight [[VideoGame/MegaMan Bomb Man]] for a while in the Energy Zone, the true boss ([[{{Contra}} Robo-Corpse]]) comes up and eats Bomb Man.
* BadassBoast: Every character gets one when confronting the TrueFinalBoss.
* BatmanCanBreatheInSpace: Evident in levels such as [[VideoGame/RType Bydo Station]], where characters can walk around outer space without special equipment.
* BigBad: Legion.
* {{BFS}}: Link's [[FinalFantasyVII Buster Sword]].
* BossInMookClothing: Covenant Elite in general, but especially the two blocking your path at the end of 8-4. You can, however, abuse MercyInvincibility to get by, making them a sort of SkippableBoss as well. [[note]](Killing the back one gets you the key to the secret exit, which leads to a goldmine of top-class powerups, so you should try to take them both down.)[[/note]]
** The [[GearsOfWar Berserker]]. She's incredibly resistant to damage and chases you down when she senses your presence. She also tends to be surrounded by bricks in such a way to make navigating around her difficult, but they don't last long once she starts charging.
* BossRush: ''VideoGame/MegaMan'' style.[[spoiler:..and one at the final stage before the Abomination.]]
* BottomlessPits: Everywhere. Non-Mario characters get to deal with knockback, making them more dangerous than usual. Good times!
* BulletHell: [[Franchise/SuperMarioBros King Watinga's]] [[OneWingedAngel second]] [[PaletteSwap form]].
* ChargedAttack: Roll, Proto Man, Zero...and a few other characters with certain power-ups.
* CheckpointStarvation: There are generally more checkpoints than in the original Mario games, but the added difficulty can give you this feeling in some levels.
* ClassicVideoGameScrewYous: The developers do their best to avoid FakeDifficulty. That said, the difficulty's part of why the fanbase loves it so much.
** Instant Death Areas abound. BottomlessPits and crushers, being familiar building blocks of the Mario series, are the favorites. Some, such as the villi from "Corpse of the Behemoth", aren't self-evident; warning comes in the form of [[VideoGame/SuperMarioWorld info blocks]], so read them!
** Fixed scrolling levels. The [[SincerityMode ever-popular]] "RUN!" sections often have some sort of instant-kill obstacle following you and taking up a certain amount of space, and the high speed takes away any margin for error.
** For some characters ContinuingIsPainful, as they live by their powerups. Again, you don't have to pick them but if you're Samus, ''don't die!''
** PoisonMushroom, in many many forms.
** It's possible for some characters, especially Sonic and Tails, to be juggled to death. This may or may not be a bug or oversight.
* CoolPet: Tango, for Roll. Replaces Mario's Tanooki suit, provides that function, and as a bonus is death on high-HP enemies who aren't bosses.
* CosplayFanArt:
** The Spartan Suit lets Mario dress up as [[Franchise/{{Halo}} Master Chief]], while Luigi dresses up as Bionic Commando. Also, they dress up as Mega Man and Proto Man for their Mega Man Suits.
** Roll wears Mega Man, Bass, [[VideoGame/MegaManLegends Tron Bonne]], and a [[Franchise/{{Halo}} Hunter's]] outfits for her Super Mushroom, Hammer Bro Suit, Mega Man Suit, and Halo Suit powers respectively.
** [[SonicTheHedgehog Sonic and Tails]] wear Quick Man's and Gyro Man's outfits for their Mega Man Suits.
** Wario is Guts Man in the Mega Man Suit and a Brute in the Halo Suit.
** Link is [[VideoGame/MegaManX Zero]] in the Mega Man Suit and the Arbiter in the Halo Suit.
** Mario's "Gunner" suit is [[MetalSlug Marco Rossi]]. Luigi's is [[StreetFighter Guile]].
* CrisisCrossover[=/=]ExcusePlot: Characters from different game franchises join forces to fight the [[BigBad the villains]] from those same franchises and more.
* DamnYouMuscleMemory: Part of the learning curve comes from having to relearn how to control favorite characters. Now subverted by ''Mega Man 10'' Bass' dash jump controls just like this game's abnormal slide jump.
* DarkerAndEdgier: Significantly, compared to the original versions of most series. What level of darker and edgier-ness differs depending upon the world.
* DemotedToExtra: Mega Man, and to a lesser extent VideoGame/MegaManX, is extremely conspicuous by his absence. This tends to lead to flame wars given the general response to an all-star video game cast...[[MyFriendsAndZoidberg and Roll]]. The former is, however, a very important NPC.
** The official reason that was given was that Mega Man had '''far''' too many weapons to choose from, and that weapon choices would be 1) difficult and 2) easily make him a GameBreaker. As they wanted ''somebody'' to represent the World of 20XX among the playable characters, Roll was chosen instead. This explanation [[VoodooShark fell apart really quickly]], as weapon choices had to be made for Roll and Protoman. The ''real'' reason was that Mega Man was an integral part of the game's story events from back when the story plans were huge and impractical. Once that story event had been cut/changed, the devs had already backed themselves into a corner by making Roll and Protoman. After a while, the devs ended up changing their minds, and now [[http://www.youtube.com/watch?v=apNrZg4zpzQ&t=3m42s he's in!]]
* DifficultButAwesome: To a certain extent, Sonic. His bounce attack allows for extremely precise jumps, but he lacks Tails' simple-yet-valuable flight powers and requires strong execution around the many, many BottomlessPits.
* DivergentCharacterEvolution: Nearly retroactive Luigi's fireballs switch to their ''VideoGame/SuperSmashBros.'' physics, he loses the Raccoon ability for the Bunny powerup, and he gets a Boomerang Bro suit where Mario receives the Hammer Bro suit.
* {{Dracula}}: The ''Franchise/{{Castlevania}}'' version, to be more exact.
* DropTheHammer: Aside from Mario's traditional Hammer Suit, we have Covenant Brute Wario's weapon and the awaited ''SonicAdvanceTrilogy''-style gameplay of Amy Rose.
* {{Egopolis}}: Robotnikland, which is also a ShoutOut to the ''SonicUnleashed'' stage.
* EldritchAbomination: [[spoiler:A disturbing mesh of all of the major villains' [[BodyHorror bodies]] serves as the game's TrueFinalBoss. [[MeaningfulName They didn't name it "The Abomination" for nothing.]]]]
* EldritchLocation: Twisted Reality, judging from its [[AllThereInTheManual description on the Wiki]]. The fact that the overworld map consists of ''nothing but static'' is a pretty good indicator of this.
* EverybodyKnewAlready: The secret characters, and the major plot points. Amusingly, the creators can't help but broadcast loudly and blatantly what the "secret" characters are, as well as their abilities and powerups -- and in several cases, how to unlock them.
* ExiledFromContinuity: If you're going to make a contribution to ''MKF'', make sure that your ideas for characters, levels, and such aren't from a game made after June 2008. Music's fine, though.
** This rule became obsolete once the suggestion forums were shut down. Now you'll see such things as ''Mega Man 10'' cameos created within months of the game's release.
* FateWorseThanDeath: Near the end of the game, Legion's Finest [[spoiler:is merged into a fearsome chimera as a punishment for their failures]].
* FragileSpeedster: Roll is quite fast in the newer versions, but the maximum number of hits she can take is 3, excluding special suits.
* FungusHumongous: It's a Mario game at heart, so of ''course'' these were going to show up.
* GameMod: All sprites, music, and backgrounds are external, so anyone who can rename a file and has some skill with sprites can do some noticeable alterations to the game. Character skins and music changes are two of the most popular fan changes.
* GiantSpaceFleaFromNowhere: Currently, the boss of Tetropolis is the obscure ''Mario Paint'' minigame boss, King Watinga. No explanation was given as to why.
* GlassCannon: [[VideoGame/GhostsNGoblins Arthur]], [[VideoGame/MegaMan Proto Man]], and recently with Roll.
* TheGoomba: They're here, along with Metools and Shy Guys.
* GoombaStomp: ZigZagged because there are characters who can't do this, but they can gain a powerup to be able to do so.
* HeelFaceTurn: [[spoiler:Bowser does this at the end of World 1. He captures Peach as a method of protecting her from Legion.]]
** At the end of the game, [[spoiler:Bowser does a FaceHeelTurn and joins the Villain Alliance]].
* [[spoiler:HijackedByGanon: The Villain Alliance does one to Legion at the end of the game. One of their members is Ganondorf, so Legion should've seen that coming.]]
* ImplausibleFencingPowers: Link's Z-Saber and Buster Sword can erase bullets if swung at the right time.
* InfiniteOneUps: The classic Mario tricks with shells or invincibility. Where these are possible, it's generally unintentional on the developers' parts some enemies don't give escalating scores when struck by shells, after all.
** The Library has both of these. It's generally considered one of the more difficult stages, but this effectively means you're dealing with MeaninglessLives.
** Taken away from one NostalgiaLevel the Transitway, World 1-1 of ''The Lost Levels'', had its Starman removed because of the ludicrous 1-up count Sonic and Tails could ring up with their great speed.
* JackOfAllStats: Averted; Mario (who this trope is usually applied to) amounts to the tank with his ''VideoGame/SuperMarioBros3'' damage progression, reserve items, and lack of knockback. Stats-wise, he's as average as ever.
* JamesBondage: Mega Man.
* JokeCharacter[=/=]LegacyCharacter: [[spoiler:Classic Mario.]]
* JumpPhysics: Many, many different ways...
* JustAKid: [[UnderestimatingBadassery Dr. Wily dismisses Tails as such.]] A standout example as he's been warned ahead of time.
* LethalJokeCharacter: Proto Man, being a far less modified ''VideoGame/MegaMan'' character, squeezes in here. Nigh unto useless at actual platforming? Check. Blows away the difficulty curve of some levels by shooting through walls? Check. Play him in "[[GearsOfWar Battle For Sera]]" and see it for yourself on both ends.
* LightningBruiser: Much like in his recent 3D outings, Sonic is tough enough to slam right through TheSpiny (while spinning) and deals relatively heavy damage with his GoombaStomp - and almost entirely lacks ranged attacks. Meta-Knight hits even harder and is more of a Glass Cannon variant. Several enemies qualify as well, especially [[GearsOfWar the Beserker]].
* LoadsAndLoadsOfLoading: It's made in ''Game Maker'' and took an obscene amount of time to start up (about 15-20 ''minutes'') followed by a lot of slowdown in-game, even on modern computers. Version 0.4 cut the slowdown issues by about 80-90%, with the game now taking about 90 '''seconds''' to load.
* MadeOfExplodium: Defeat a boss in this game, it explodes spectacularly. Averted by Mouser from ''VideoGame/SuperMarioBros2'', who just falls off the screen when he's defeated. {{Subverted|Trope}} by King Totomesu who, in his original appearance in the first ''VideoGame/SuperMarioLand'', exploded, while he '''doesn't''' explode in MKF. And then there's [[UpToEleven Air Man]].
* MarathonLevel: Some levels are so long, they either have four digit time limits or none at all.
* MegaCrossover: There's so many damn games featured, it could be called an Ultra-Crossover. [[http://www.youtube.com/watch?v=Vp7Y_d636YI The Crossroads level]], in and of itself, is a MegaCrossover.
* MergedReality
* MoeAnthropomorphism[=/=]CuteMonsterGirl: Covenant Hunter Roll.
* MightyGlacier: {{VideoGame/Wario|Land}} and [[spoiler:Simon Belmont]].
* MixAndMatchCritters: The [[http://youtu.be/fq_ITPF9f2Y Lab of the Fusionist]] level features fusions of enemies from throughout the different realms, such as a Goomba with a Piranha Plant on its head and an [[SonicTheHedgehog Orbinaut]] with Metal Slug cannons in place of spikes.
** There's even a Cacobirdo (mash-up between a Birdo and a [[VideoGame/{{Doom}} Cacodemon]]) as a mini-boss, [[spoiler:along with a [[http://youtu.be/YtLscpx-sn8#t=2m2s FloodCacobirdo]]]].
* MutuallyExclusivePowerups
* [[spoiler:MyHeroZero: Wanna guess who?]]
* MythologyGag: Some of the {{Self Imposed Challenge}}s in the community are of this variety; for instance, "[[DoesntLikeGuns I wouldn't be caught dead with one of those!]]", an unarmed run as Sonic through a war zone, is named for a line from ''ShadowTheHedgehog''.
** [[spoiler:Roll's Nightmare stage is a darker version, and possibly a TakeThat as it's all about Roll and her expies being the eternal sidekick.]]
* {{Nerf}}: Several old-school {{Game Breaker}}s return in vastly depowered form. ''VideoGame/SuperMarioWorld'''s Cape and ''VideoGame/MegaMan2''[='s=] Metal Blade are the big ones.
* NintendoHard: Unlike the [[HardLevelsEasyBosses Mario games]], this game has Hard Levels, Hard Bosses.
* {{Ninja}}: [[spoiler:[[NinjaGaiden Ryu Hayabusa]].]]
* NinjaPirateZombieRobot
* NonStandardCharacterDesign: Happens quite frequently, especially when the playable characters go into settings not based on their respective series. [[JustifiedTrope Due to the crossover nature of the game, this makes sense.]]
* NoSell: See PuzzleBoss, below.
* NostalgiaLevel: Plenty of them... as well as subverted. Most Mario fangames include a remake of [[VideoGame/SuperMarioBros1 World 1-1]], but in ''MKF'' it's a remake of World 1-1 from ''Super Mario Bros. 2''-er, ''VideoGame/SuperMarioBrosTheLostLevels''.
* OneSteveLimit: The BigBad Legion is ''not'' from the ''Franchise/{{Castlevania}}'' series. [[TheGhost So far.]]
* PlatformGame: Erm...yeah.
* PoisonMushroom: The TropeNamer, and its {{Exp|y}}ies from the games it's based on, are here.
* PowerCreepPowerSeep: With interesting implications for characters from the same universe. [[spoiler:Since everyone's balanced with [[VideoGame/MegaMan Roll and Proto Man]], [[VideoGame/MegaManX Zero and Vile]] are awarded a GoombaStomp (an ability foreign to their original appearances) on top of their firepower, turning them into [[InfinityPlusOneSword Infinity Plus One Reploids]].]]
** It's merely temporary as soon as the wall kick is coded in, they will lose their stomping ability.
* PoweredArmor: Samus Aran.
* PowerupLetdown: Averted in a couple of significant cases -- the Blue Shell powerup returns from ''VideoGame/NewSuperMarioBros'' and is slowed to a far more manageable pace, while Arthur's golden axe is death on any enemy without a damage cooldown and is less likely (because of the sprite scale) to simply crash into a wall. [[VideoGame/MegaMan Skull Man's weapon]] still sucks.
* PuzzleBoss: A significant number of bosses are immune to "normal" means of damage.
* QuirkyMinibossSquad: Legion's Finest.
* RandomlyDrops: Getting ahold of the particular weapon you want for either Arthur or Roll.
* {{Recurring Boss}}es: [[VideoGame/MegaMan3 Doc Robot]], [[VideoGame/SuperMarioBros2 Mouser]], and [[SonicTheHedgehog Robotnik]].
* RemilitarizedZone: The Scandinavian Campaign and Covenant Assault levels. Also the Military War Zone level, which is basically a war-torn city in ruins. Pretty much the majority of the later levels in World 2 (Alternate Earth) will be like this.
* RobotGirl: Roll.
* RunningGag: How long will it take for the project to get completed? The fans aren't sure anymore due to the sheer amount of new content announced regularly. People have resorted to making jokes about how long it'll be for ''MKF'' to be completed, with estimates ranging from 2012 to 2020 (the project was started in '''2008''').
** The current forum banner has "Developed by Fusion Team (2008 - 20XX)" along the bottom.
* SaveThePrincess: [[spoiler:Played with. Kidnapping Peach is more or less just a way for Bowser to get the attention of Mario and Luigi.]]
* SchizophrenicDifficulty: Sure, the toughest stages are at least denoted on the world map, but the difficulty level of specific levels doesn't have a ton to do with what world you're in. To be fair, you may easily find yourself jumping back and forth between the worlds on a regular basis.
* SecretCharacter: [[spoiler:R.O.B., [[Franchise/{{Castlevania}} Simon Belmont]], [[VideoGame/MegaManX Vile]], [[NinjaGaiden Ryu Hayabusa]], [[SuperMarioBros Classic Mario]].]] And that's just the ones that have been ''announced''.
* TheSmartGuy: Tails.
* TheSmurfettePrinciple: More or less a result of using an all-star cast of video game characters. Aside from Samus, some effort has been made to avert the trope -- this was part of the argument in favor of the now-scrapped OriginalGeneration character Agent M, and the inclusion of Roll over Mega Man owes itself in some part to defeating the trope. The forums tend to get behind female characters for {{Shotoclone}} status; [[SonicTheHedgehog Amy]] appears to have been confirmed, and support for [[NinjaGaiden Rachel]] appears every now and then.
* SoundtrackDissonance: Calliope the Clown is a whimsical and goofy clown boss that jumps around and punches the living daylights out of you with spring-loaded boxing gloves. His boss music? The serious ''{{Gradius}} V'' boss music.
* SpellMyNameWithAnS: Eggman goes by his old Robotnik moniker throughout, yet is played by [[VideoGame/SonicAdventure the late Deem Bristow]]. Go figure.
* TheSpiny: The one and only, including the ones that walk on ceilings. Of course, the Spiny itself isn't the only spiky critter...
* SuperNotDrowningSkills: Yep, there's water levels. Even the characters who can't swim (like [[SonicTheHedgehog Sonic]]) have SuperNotDrowningSkills in this game, though they'll need a life jacket powerup to move through water easily.
* SurpriseCreepy: And how!
* SuspiciousVideoGameGenerosity: The rooms before fighting most bosses include a save gate and three powerups, more or less assuring you'll at least have a decent chance at victory.
* SwordBeam: Link when wielding [[VideoGame/MegaManX the Z-Saber]], not to mention [[spoiler:[[VideoGame/MegaManZero the man...er, reploid himself]]]].
* ThrowTheMookAtThem: The game occasionally offers variants of its source games' bosses who veer into this, such as a version of [[SuperMarioBros2 Mouser]] who tosses Bob-omb enemies or a variant of [[SuperMarioLand King Totomesu]] with lots of hit points and an unusual vulnerability to the exploding Koopa variants that spawn endlessly during the battle.
* TomboyAndGirlyGirl: Samus and Roll, respectively.
* TookALevelInBadass: Roll goes from swinging her broom in ''MegaManPoweredUp'' ([[ImprobableWeaponUser admittedly, fairly well]]) and being the eternal joke character of the pre-''Tatsunoko vs. Capcom'' CapcomVsWhatever games to having some of the most potent high-level powerups of any playable character. [[GlassCannon You may be in trouble without them, though...]]
** Several returning boss fights have been altered to bring them up to Kirby-type boss difficulty. The Tree Zone boss found himself a tough boss room and got a projectile weapon in the process.
* TrialAndErrorGameplay: The popular "Run!" segments are loaded with extra lives for a reason -- hazards will sometimes come at you faster than you can respond on a first run. [[spoiler:Heaven only knows how bad something called "Speedway Of Screams" will be...]] It's also tough to tell off the bat what will and won't damage certain bosses, or which attacks do how much damage to a specific boss opponent.
* TrueFinalBoss: [[spoiler:The Abomination.]]
* UltimateEvil: Legion, to the point that even the ''developers'' have no idea what he looks like ([[ScheduleSlip for obvious reasons]]). Though, they did come up with a base form for him.
* UnexpectedShmupLevel: All of World 6 was going to be this, before it was changed to Adventurer's Domain.
* TheVeryDefinitelyFinalDungeon: [[spoiler:The Castle That Doesn't Make Sense.]]
* VillainTeamUp: The Villain Alliance.
* WakeUpCallBoss: The Siren, fought towards the end of the first world. The arena consists of a few small platforms over a pit of piranha plants, and the Siren herself takes much more damage than anything else you've fought, has a variety of attacks that can throw you off, and a singing attack that paralyzes you.
* WombLevel: Corpse of the Behemoth, Lair of the Leviathan, and The Castle of Meat.
