It's so simple, yet so complex. It's the perfect Fighting Game formula! HUEHEHEHEHEHEHE!
If you're looking for the character called "Mugen", look here: Samurai Champloo

"Mugen" is Japanese for "infinity". M.U.G.E.N., however, is a freeware 2D fighting game engine designed by Elecbyte, written in C with the Allegro library.

The engine was originally released in July 17, 1999. Beta versions of it were made to work on DOS, Linux and Windows platforms, distributed through their website. The engine allows users to insert created characters, background stages, and other game objects through interpreted text files, graphics, and sound compilations to create a functioning fighting game similar to commercial games. While the engine is set up primarily for fighting game development, several other game types have been developed using it, including shooter and platform style games. Officially, Elecbyte claims to have forgotten what the acronym M.U.G.E.N stood for, but the readme documentation states that its meaning referred to the days when the engine was meant to emulate shooting games as opposed to fighting games.

The engine allows anyone to create characters, background stages and other game objects through interpreted text files, graphics, and sound compilations. It supports various types of audio formats such as MP3 and MIDI initially, although it can be configured to play various audio formats via Winamp plugins, such as ADX and OGG, as background music during gameplay or at other points such as an introduction or the select screen. The engine allows for most of the same type of functionality found in most any commercial 2D fighting games, up to and including close recreation of those games' characters and gameplay.

Nowadays, though, a vast majority of the first wave of M.U.G.E.N sites have either not been updated since 2010, or have been shut down. Because of this, finding certain characters is almost impossible.

DOS and Linux versions

First released on July 17, 1999, M.U.G.E.N was initially created for MS-DOS. Development of the DOS version ceased when Elecbyte switched to the Linux platform in November 2001. For a time, Elecbyte had posted a request for donations on their site to legally obtain a Windows compiler to make a Windows version of M.U.G.E.N. However, the development group discontinued the project in 2003 and shut down their site. Later speculation pointed at leaks made public of a private Windows-based M.U.G.E.N beta that was provided to donators.

Windows version and subsequent hacks

The private WinM.U.G.E.N beta contained a two-character roster limit, locked game modes, and nag screens. With the beta leaked and Elecbyte gone, a "no limit" hack that removed most of these limitations was made available in 2004 by Rou Hei, followed by subsequent updates to deal with bugs and other issues. This version of M.U.G.E.N. is functionally the same as the last Linux release, though with subtle differences and unique issues, mostly revolving around proper music and music plugin support. Because of the changes between the DOS and Linux versions of M.U.G.E.N however, many older characters required at least the SFF files to be modified to show palettes correctly (notably on portraits) as well as some changes in how certain CNS script controllers functioned, causing some minor upset and those that could still run the DOS version in some form sticking to that, as well as DOS patches to downgrade characters to be compatible with the older version of the engine.

In May 2007, a hacked version of WinM.U.G.E.N was released by a third party that added support for high resolution stages (like those seen in Guilty Gear X) at the cost of losing support to standard resolution M.U.G.E.N stages. Later that month, another hack was done to add support for high-res select screens. In July 2007 another hack created by Sion and Kung Fu Man based on the last high-res hack allowed for only the select screen to be high-res and not the stages. In December 2007, a hack from an anonymous source allowed both low-res and hi-res stages to be functional in the same build, requiring only a single line of code to be added to hi-res stages.

Elecbyte's website and the return of the M.U.G.E.N engine

In mid 2007, Elecbyte's site returned, though not without some controversy as to the legitimacy of it, as it only showed a single logo with Google ads on the side. On July 26, though, a FAQ was added to the site. This FAQ went on to claim that they would release a fixed version of WinM.U.G.E.N before major format changes in the next version, and noted the formatting changes would remove compatibility in regards to older works: "Do not expect old characters to work. At all."

Despite some widespread agreement that the new site was a fake, things changed roughly two years later, when a new release candidate, MUGEN 1.0, was added to the site, with Open GL support as well as proper HD display options, victory quotes, improved (and growing) stability as a whole. The claim of widespread incompatibility of old works with this engine turned out to be false, as Elecbyte took steps to ensure that at the very least properly coded characters would not malfunction in the new engine (or would require minimal updates), though screenpacks are not necessarily subject to the same rule. As of January 2011, MUGEN 1.0 is no longer in the "Release Candidate" stage, and MUGEN 1.1 has been released on August 6th, 2013.

Clone projects

When development of the WinM.U.G.E.N engine stopped, several clone projects started to try and duplicate the functionality of the engine from scratch, such as ShugenDo, InfinityCat, xnaMugen and Open Source Mugen. Some of them presented online gameplay capabilities, a feature many users have sought after. Some clones currently in development are IKEMEN, its cousin BIJIN, and Paintown.

For more information, check out these websites:

  • Elecbyte's website.
  • The Mugen Fighters Guild - The basic start point for many MUGEN players. Highly recommended if this is your first time using the engine.
  • MUGEN Genesis - Created by Gamefreak202020. No longer active.
  • Phantom Gs - MOTVN and Hank Venture's community. Formerly welcome to the public; registration is now closed.
  • Random Select - A large database for characters and stages. Currently home to the BIJIN engine, an offshoot of the MUGEN clone IKEMEN.
  • Stupid Dope Mugen - Product of Crazy Koopa and MC2. Sadly no longer active.
  • Mugen-Infantry - A branch forum from the Guild, started around 2004 by DJ-Van, the guy who created the EVE Battle screenpack, and some other guy named Aztec Soldier who has since abandoned his admin duties due to a massive addiction to Halo. Most notable for its constant server downtime and maintenance throughout the years. Has figuratively gone through hell and back, as the entire site was shut down due to Aztec not paying the bills, but it was eventually revived on Blogspot. In 2009 a revolution broke out when the Random Insanity section was removed, which caused the formation of Genesis, as shown below. It has since been brought back, but with roughly half of its supporting members gone. The forum is currently back up and running, though time will tell if it ever regains it's former activity.
  • MUGEN Motherland - PrinzJanus' Forum, formerly known as PrinzMugen. Built initially as an alternative to more serious forums, Motherland presents a more casual tongue-in-cheek approach to the engine, focusing more on the playing aspect than actual serious creation and testing. It reformed itself due to complications with the old hosting. Now inactive.
  • Trinity Mugen - Created by Vans, Jesuszilla, and Fusion around 2005, it is as its name suggests. Home of many a worthwhile character and will provide hosting services if necessary). Forum is not much active, most of the action is at the IRC chat.
  • http://mugencharacters.ucoz.com/ - One of the larger databases of MUGEN characters available today, it has just about every character ever made, including some that are otherwise all but impossible to find at all (other websites just list them as being "offline," or worse, they're only hosted on Phantom Gs). Unfortunately, as a corollary, it has just about every character ever made. Additionally, it hosts its own copies of everything, which annoys no small part of the community; CTRL+F "Warehousing" below.
  • The MUGEN Archive - Probably the larger database in existence, even more than mugencharacters or any other of this list. As mugencharacters, MUGEN Archive had a lot to do with Warehousing, but in these years has been redeemed having its own forum where creators also can upload their characters there and uploading characters and stages that have been offline since years as well works from offline/retired creators.
  • http://mugenchara.blog.shinobi.jp/ - A Japanese MUGEN blog, with a character/stage entry added nearly everyday. It only links content to their original downloads. A translator tool is required for most users.
  • SaltyBet - It's like betting on boxing or MMA fights, except instead of Mike Tyson, you get magicians who beat you up with dolls and lasers (sometimes both), Superman, robot ninjas and undead ninjas who brutally murder their opponent, crossdressing nuns, princess vampires, robot animals, killer mecha, a children's mascot with an assault rifle, a giant, fat, pink demon and human aliens and fancy golden hair who spew poorly-ripped, badly-acted Spanish, and, of course, Mike Tyson himself. Oh, and the money isn't real. The rules are simple: you start with 400 Salty Bucks. You lose it all, you get put into the Salt Mines with a bailout of only 10 Salty Bucks, and must work your way back to freedom. There is also a premium service if you make a real-life donation called the Salty Illuminati which allows you to access the Compendium, a sacred scripture containing character statistics and matchup odds. In Salt We Trust.
  • MUGEN Database - Using a Wikia template, the Database is one of the more up-to-date websites, focusing on archiving and providing sources for characters and stages.
  • Mugen Free For All - Another community that focuses on archiving materials for the engine, providing detailed directories of characters and stages that are kept as up-to-date as possible. With the members pretty adept at finding things that are extremely hard to find. Unlike most archive sites it also home to it's own group of creators and their own original creations.

For the sake of not turning this article into another list of character tropes, please avoid adding entries for characters which aren't exclusive to Mugen, as tropes associated with characters from existing series can have theirs listed in their series' page.

M.U.G.E.N-based games with their own pages:

This engine, its community and sometimes games made with it (including itself) provide examples of:

    open/close all folders 

    A-C 
  • Adaptational Badass: Pingu, Garfield, Homer Simpson, Princess Peach... In general, any character who was a non-combatant in his/her source material can throw down like ever before.
  • Aerith and Bob: When you have a crossover between many games, this is going to happen.
  • A.I. Breaker: Some characters, such as mob-type characters and massive boss characters, have a tendency to confuse AI controlled characters. One Kung Fu Man edit, AK Man, invokes this trope by completely shutting off opponent AI and leaving them helpless, and even then there are a few characters that can still defeat him.
  • Amazing Technicolor Battlefield: When projectiles, clothing, and the background tend to be all the colors of the rainbow, it's bound to happen. Even drab urban settings or grim Mortal Kombat stages can get quickly colorful.
  • Amazing Technicolor Population: With custom palettes, this is possible for just about anyone. The character literally named "Ms. Fanservice" (actually a joke edit of Yoko), for example, has blue, dark blue, red, and gray-skinned schemes. That's not getting into the characters who are already technicolor, or extremely broken examples like the infamous "retarded" Peter Griffin (who has a new color scheme for just about every sprite thanks to a lack of any loaded palettes).
  • Anachronism Stew: When you have characters from fighting games that take place during different time eras, this happens.
  • Anthropomorphic Food: The Dancing Banana, a dancing banana with arms and legs who is also a surprisingly dangerous fighter.
  • Artificial Stupidity: Many characters, even those with perfect AI, break against mob-style opponents, such as the Alien Queen's xenomorph swarm, the Biohazard, and the Mad Gear Gang. Many AIs also don't avoid (or try to guard) the Stupid Little Drill Tank's unblockable drill, taking huge damage in the process.
  • Assist Character:
    • Some characters have built-in assist characters (usually referred as Strikers like in The King of Fighters), some of them like Juza who had them in source game, but the majority of characters with built-in assist characters have them because of the engine's limitations.
    • The Uno Tag System lets you do this with many characters.
  • Attack of the 50-Foot Whatever:
    • Doable, in the vein of Apocalypse from X-Men Vs. Street Fighter, with proper application of art and hitboxes. Bizarrely averted with Godzilla and Gundam fighting characters... buuutttt there are some stages that allow you to do this (with, strangely enough, Godzilla and Gundam stages). Same goes with EVA and Primal Rage characters.
    • It is possible to edit the .def file of literally any character you have, and most of them have a "scale" option. This can result in you beefing up the size, and therefore hitboxes and attacks, of anyone. A giant 55 ft Ryu from Street Fighter who is so tall he's going off screen? No big deal.
  • Back Stab: Literally for The_None's Segalow, who has a level 3 super where he grabs the opponent and if he does so he slashes them. If its done when they're facing him it does moderate damage, but if it connects from behind, it does MASSIVE damage. He does have elements of The Spy after all.
  • Badass Adorable: Ranging from moeblobs of various anime (Haruhi and Konata were massively popular in their heyday) to, of course, the new batch of My Little Pony.
  • Badass Normal: Anyone who doesn't throw fireballs/shoot lasers/doesn't mutate/isn't magic can beat up homocidal robots, killer aliens from outer space, evil psychic projections made from two mutants that happens to be bigger than a skyscraper, and actual Gods. Kung Fu Man is one of the normals, in that he doesn't even have a single projectile attack.
  • Battle Aura: Common when characters power up and/or use Heat / Blood Heat.
  • Bee Afraid: Someone created a character based on a wasp nest. It just sits there until someone attacks it and then it releases a swarm of wasps to overwhelm the enemy, most of the time combo-locking them in place. Not even Juggernaut or The Incredible Hulk are a match for those vicious wasps!
  • Beyond the Impossible: There are characters who can win the battle before the match even starts, something that never occurs in any other Fighting Game. It is also a literal breaking of the game's rules, in the sense that their code overloads the game that the opponent fails to load and is thus defeated.
  • Bloody Murder:
    • Giygas' fatalities, which are jacked from EternalChampion's Overkills - but are somehow much more scary, even though they're relatively untouched straight rips.
  • Boss Rush: The NES Ninja Gaiden bosses have been made into a boss rush of its own.
  • Break Meter: Some characters have this. For example, Evil Kung Fu Man will get dizzy if hit enough times in short order, rendering him vulnerable.
  • Bruce Lee Clone: Bruce Lee himself is in there.
  • Cast from Hit Points: Homer Simpson's "Riot of The Beer" mode. It makes all of his attacks much stronger, and gives them greater priority, but using it costs half of his remaining health.
  • Chainsaw Good:
    • Sadako look-alike and general horror movie tribute character, Ella. Duke Nukem has a special palette that gives him the Doomguy's chainsaw. After he blows up Doomguy and steals it.
    • Evil Kung Fu Man's foot turns into a chainsaw.
  • Chekhov's Gunman: A meta-example. Anyone and anything encountered outside of MUGEN has a good chance of eventually being adapted to it.
  • The Computer Is a Cheating Bastard:
    • One example is certain characters not requiring a minimum level of power to do their hypers when controlled by the AI, but require power when controlled by the player.
    • Omega and Shadow Omega from Megaman have been programmed by the creator to purposely never use any of their meter when they're being fought as CPU opponents. This allows them to infinitely use Super-based attacks without ever draining meter. This leniency only affects the CPU, the player doesn't get the same privilege when controlling Omega.
  • Crossover: Very often used for this, although gameplay styles won't necessarily mix well, particularly when Guilty Gear, a game known for being much more notoriously fast-paced and complex than other fighting games (on top of ludicrously cheap AI) is involved.

    D-F 
  • Damn You, Muscle Memory: The possibility of a MUGEN build having characters coming from different source games (complete with distinctive control schemes of such) tends to get some players mixed up when getting to know or use new characters.
  • Death of a Thousand Cuts:
    • There are many characters who's attacks will hit the 999 combo meter. It's mainly overpowered characters.
    • This is particularly funny in reverse when facing a weakly programmed AI, such as Alex Mercer, against a much stronger AI opponent, say Ika Musume, who will combo him to death for several minutes while he flails through the air helplessly.
  • Deconstruction Game: M.U.G.E.N. can be seen as a deconstruction of crossover fighting games (As well as games with guest characters), as you can see the far more realistic consequences of having characters in your roster with widely different rules and gameplay. Gaze in awe as characters from games with the simpler mechanics note  are mercilessly demolished by characters from fast-paced, combo-oriented games note , or games with more complex mechanics note .
    • Decon-Recon Switch: Although to be fair, thanks to the customizability of the engine, it is possible to rewrite the files and states of your characters, weaken the overpowering ones and buff the weaker ones for a proper balancing.
  • Defeating the Undefeatable:
    • Over and over again. Chuck Norris, a literally invincible Lethal Joke Character based on Chuck Norris Facts. He actually has been defeated before. Before that? He maimed several undefeatable characters with the same hitbox-less advantage, such as the previous Oni-Miko. And people have been trying to one-up Oni-Miko and everyone else since.
    • Both Chuck Norris and Oni-Miko-Z (and countless other "unbeatable" characters) have fallen to the Debugger character, two floating strings of numbers that "delete" the opponent's root file, causing them to be read as nonexistent and dead.
  • Depending on the Writer:
    • If about two or more makers share the characters they've converted, don't expect them to be both exactly the same.
    • Few makers also are quite creative in their takes on certain characters. A good example would be The_None's Possessed Heita, who has a mode that comes with Captain Falcon's moves and voice. (Influenced heavily with the works of 3ha, which are almost 2 in 1.)
  • Did You Just Punch Out Cthulhu?:
  • Digital Piracy Is Evil: Two forms of it.
    • "Warehousing" is the practice of hosting a character on a website without the creator's permission. In some MUGEN circles this is regarded as a disrespectful and dishonest practice, while others simply aren't concerned about it.
    • The second one, much more subject to ridicule, is known as "spriteswapping". The "creator" takes another character, and replaces the original character's sprites with his own sprites. In particularly bad cases, the spriteswap will retain the base creation's gameplay elements even if it doesn't match the spriteswap's playing style. In even worse cases, the creator doesn't even change every single sprites, causing the character to briefly "flicker" back to the original one during certain frames. Many spriteswaps also tend to have jacked-up stats, making them cheap and over-powered, like so. Warner creations are infamous for doing this, especially his first characters like Homer (spriteswap of CVS Iori Yagami).
    • Subverted in the case of sprite-ripping characters from games (such as Ryu) and using them in MUGEN. Capcom was asked about this early in MUGEN's existence, and the company stated that they consider it a form of fan art (so long as no one sells the characters, of course). Pretty much every other company has followed Capcom's attitude.
  • Ditto Fighter:
    • Ditto is actually in this game now, and it transforms into other Pokemon as its attacks.
    • Characters that are designed to be Ditto fighters, such as Unknown from Tekken, end up typically with an attack style that is mostly a mishmash of attacks from characters, granted the difficulty of a programmer actually creating a character that duplicates the moveset of another player.
    • Inverted with Dhalsims, whose "Yoga Evolution" level 3 super transforms the opponent into Dhalsim.
    • The [=MegaBrony='s Queen Chrysalis. She turns into Mega Man, Proto Man, Tomahawk Man, Hard Man, and Zero.
  • Dramatic Disappearing Display: Some characters have a code that hides the entire GUI (lifebars, victories, powerbars).
  • Easter Egg: Some fighters have special entrances with other fighters, and sometimes special ending poses. Deadpool, for example, has special entrances with Iron Man, Captain America, Batman, Cyclops, The Juggernaut, Ghost Rider, and The Mighty Thor.
  • Edible Ammunition:
    • Dancing Banana fires large bananas of varying sizes as projectiles.
    • Garfield throws Hotdogs as projectiles.
    • Homer Simpson throws Donuts as projectiles and one of his specials is Hell Candy Bomb, a candy bar that stuns the opponent for a short time.
    • Spongebob throws Krabby Patties as projectiles.
    • Nev throws ice cream as a projectile.
    • Hotel Mario uses Toast. One of his specials is firing a stream of jpeg Toast at the enemy. Hotel Luigi uses Salami and Spaghetti, and his special is firing jpeg Spaghetti. They can also fires Instruction Books, Toasters, Pennies, and use a jpeg gun, but the most you will see in a match are the food ones.
    • King Harkinian is a projectile spammer that throws "Dinner".
  • Epic Fail: Whenever Homer is involved, as of Vs Iori, who falls on his ass, to Goku, of which Homer poses as Goku, Super Saiyan and all...until he farts.
  • Fan Disservice:
    • When Demitri uses his Midnight Bless attack on certain characters, the results may not be pretty.
    • It's not impossible to have a character with hentai-based sprites hidden in its design that are only revealed in Fighter Factory, or sometimes by total accident when using them.
  • Fartillery:
    • Peter Griffin uses farts as a flamethrower (known as the Anal Torch) and also uses farts like a hadouken.
    • The goblin character Menelikke does the same in his super. There's also the giantess Delilah who, in one of her alternate versions, has a full screen gas attack.
    • And there's also Gustavo, whose only attacks are... well, farts, when attacked.
    • Most_Mysterious played with this. Some of his characters have moves that have farts as a hitsounds (notable examples include Dink Smallwood's (who doesn't seem to even look like the character he's supposed to be.) Big Mother Ducker (also appearing as Skullman's striker) and Omega Tiger Woods's Shrimp Bus supers).
    • Iggy's throw has his Stand grabbing the opponent and Iggy jumping up to said victim and farting on his face.
    • Hige, a lethal joke character based on Clone Zero of the King of Fighters, has the 'Zero Fart' move... with ACTUAL farting noises. A variation of this is a super move...
  • Fighting Clown: There are quite a number of characters that look and act silly but otherwise play like a normal one. Examples include Dancing Banana, many of The_Noone's characters (especially Dee Bee Kaw), DDR/Telechy's cartoon characters, Dialog Boxnote , etc.
  • Finishing Move: It's not uncommon for a character's super to be used as this. And that's not counting characters from games that explicitly have finishing moves, such as Mortal Kombat, the Fist of the North Star fighting games, and Sengoku Basara.
  • Foregone Victory: Certain cheap characters can exploit the system itself, causing them to win even before the match begins.
  • Frickin' Laser Beams: Many fighters can shoot beams.
  • Fusion Dance: Segalow is a weird fusion of Seth from Street Fighter IV, Rugal (uses his Capcom VS SNK sprites but with the moustache shaved off) and Lazlow of all people as one his voices is taken directly from Grand Theft Auto 3, his KOF XI lifebar port is Lazlow's Vice City artwork and his flavor text on The_None's site is a direct transcript of some of Lazlow' dialogue from GTA 3. He also has elements of Ray Park who played Rugal in the KOF movie as well as Darth Maul (His big port is KOF movie Rugal and he has a super involving a double-bladed llightsaber.) and The Spy. Oh and he also has The Spy's Dead Ringer.

    G-I 
  • Gainaxing:
  • Game-Breaking Bug: Certain matchups can lead to one character being unable to land a single point of damage on the opponent, both characters being unable to damage each other at all, or outright malfunctions in the engine, due to the different codes used with each character and/or sloppy coding.
  • Game Mod: There are a few mods/tools that can alter the MUGEN engine. Such as the Uno Tag system, which allows characters to tag out with their partners.
    • There exists a Smash Bros. system for MUGEN. Now you can duke it out with your favorite fighters, Smash Bros. style!
  • Gender Flip: There's the infamous Midnight Bliss...
  • Glass Cannon:
  • A God Am I: Any "God" version of a character. Happens literally with the Primal Rage trio of Diablo, Talon, and Happens, who, uh, are gods.
  • Godwin's Law:
    • The "X-Form" of The_None's Skullman has a counter move in which he hits you while being shaped like a swastika.
    • And yes, an Omega Adolf Hitler character exists.
  • Gone Horribly Right: Meta example. So you want something where every fictional character you ever knew and loved fights? Here you go. Unfortunately this also resulted in many of said characters being cheap, poorly made, unfinished, and/or not at all true to their original game. That, or horrible, horrible imbalance in fights between different styles of fighters.
  • Gorn: Several characters in the MUGEN roster, such as those from Mortal Kombat, are fond of gory ways of finishing off opponents.
  • Green Hill Zone: Several people have even created the Trope Namer.
  • Immune to Flinching:
    • Super Armor, and its upgraded, permanent variant Hyper Armor prevents a character from flinching when hit. This can be coded onto a character via the Hit Override function.
    • Frost Man takes this trope Up to Eleven as he has Hyper Armor. Because he can't be flinched, he can tank hits and deliver many attacks that are hard to interrupt (though there are certain fighters that may stopped Frost Man with a few certain moves.) Not to mention, he cannot be grabbed or stunned. It's possible for Frost Man to beat a few cheap/brutal AI characters or fighetrs who rely on spamming projectiles/multi-hit moves. He does slow down a bit if he's hit multiple times.
  • Improbable Weapon User:
    • Deadpool has a sheep with a cannon to its back in his special.
    • Garfield uses hot dogs as projectiles.
    • Pingu and Finn use snowballs as projectiles.
    • White Len has been known to attack with kittens.
    • Dancing Banana uses oversized bananas as projectiles.
    • POCKET SAND
    • SpongeBob uses bubbles and Krabby Patties as projectiles.
    • Princess Bubblegum uses beakers as projectiles that explode on impact when it hits the ground.
    • Sonic uses rings as projectiles.
    • Homer uses doughnuts as projectiles, along with the Hell Candy Bomb.
    • Peter uses beer bottles and his lit farts as projectiles.
    • Adam Admuson can use a Game Boy, a spiked ball (named Mr. Spickles), and a Neural Stunner as projectiles.
    • Daniel can use a Galaxian, Cirno, and the Barrel as projectiles.
    • Bob and Cartoon Guy can use rocket fists as projectiles.
    • Chaos beat Peter to the punch and uses a slow-moving, noxious cloud of fart.
    • Bridget uses modified yoyos.
    • Taz uses burps.
    • Chowder spits out fruit as projectiles.
    • Omega Tom Hanks attacks with posters of his movies and an exploding dog.
    • Hastur, an Orochi/Mizuchi edit which is a lethal joke character, fires projectiles of Mizuchi with certain attacks.
    • Hige can throw Igniz, Krizalid and Original Zero at his opponent.
    • Nev can throw ice cream cones.
    • Cyberbots R.A.D. attacks using his cannons, both with missiles, and simply punching the opponent with them. Given it's a giant Tank, this is pretty absurd and funny.
  • Improbably Female Cast You can choose to have an all female roster, or an all male roster.
  • Improvised Weapon:
    • Rorschach. Hairspray. Cooking Fat. Grappling Gun. Toilet. Numerous Others. Hurm. Deconstruction. Lethal and Gruesome Results.
  • Indy Escape:
    • The Trope Namer boulder sequence has been created as a "boss" stage.
    • The Murder Wall from Kid Chameleon must be outrun as well.
  • Inevitable Tournament: it had to happen. Some MUGEN forums hold tourneys for fun. While most follow a standard format (usually 1 vs 1 or 4 vs 4), some have fun twists on the genre.
  • Instant Death Radius:
    • Oni-Miko-Zero. Literally. Put her up against any character (save for a few) and that character is DEAD even before the battle starts...
    • The "Debugger" character uses a code that somehow deletes the opponent's root state, causing them to be read as nonexistent and thus KO'ed before the round starts. So far, it can beat Oni-Miko Zero and Chuck Norris with no effort, and is possibly the cheapest character ever.
    • The latest versions of uber-cheap characters (known as "Postman" or "Secretary" characters) run an .exe that affects the game such that only characters with their name are allowed to win.
  • Invulnerable Attack: Known as "Infinite Priority" here. A favorite of SNK Bosses, cheap characters, as well as "retarded" characters.

    J-L 
  • Jack-of-All-Stats: Amongst examples, there's Kung Fu Man, a character that comes with any downloaded copy of MUGEN (mostly as a base for making characters, and a coding example) that eventually became the mascot of the engine.
  • Jerkass: A prominent character trait of certain community individuals.
  • Joke Character: Rare Akuma, Chuck Norris, the Zeeky H-Bomb, Omega Tom Hanks, Omega Tiger Woods, and in general, characters that are so hilariously overpowered that you don't mind them.
    • And then we have characters who are actual jokes: For example, recently a character was released out there, called "Pots Styled Eltnum"; at first you might think it's an edit of Eltnum by creator Phantom Of The Server (aka P.O.T.S.), but then you realize it's Exactly What It Says on the Tin: a swarm of pots with Eltnum's face in the front of each.
    • Beatdown characters in general, like Sandbag. These practically do nothing but stand in one place and take damage from everything until they die.
  • The Juggernaut: While many characters fit the mold, The Duane exaggerates this. He can one-shot nearly every character in the game, has an obscenely huge hurtbox inversely proportional to his hitbox, and if you do manage to hit him, good luck trying to repeat it over a hundred more times.
  • Jump Scare:
  • Certain edits of Ronald McDonald have actual screamers coded into them to throw the player off in the 2nd round.
  • Kamehame Hadoken: What's a fighter without it?
  • Kiai: Being a fighting game engine, there are many examples. The most particularly notable one is the JoJo's Bizarre Adventure "WRYYYYYYYYYYYYYYYY!" (Used when anybody uses the Steamroller or when Chuck Norris drops the sun on his enemy.)
  • Kung-Fu Jesus: As a MUGEN character. Yes. So are God and Satan, courtesy of Adult Swim's Bible Fight.
  • Lazy Artist: Rather common, especially when new Shotoclones are involved. However, this is sometimes justified, when creators use characters as bases for their distinctive creations (e.g. the majority of the MvC-styled Mega Man characters, which use Mega Man as a base).
  • Lethal Joke Character:
    • The Dopefish, Zeeky H. Bomb, Slot Machine, The_None's Sue Sakamoto (aided by Logan Keller providing blind fire), Neco-Arc
    • Wobbuffet. Like its original source, its only form of damaging the enemy is via Counter Attack. However, the power of its counter against physical attacks increases if it takes a hit when swinging, making it able to kill otherwise-broken characters in one hit. And it gets leftovers and Shadow Tag as moves. Finally, it also gets Destiny Bond, which K.O.s the opponent instead should Wobbuffet get K.O.'d when the move is active.
    • There's also Rolento's Yoshi, whose movelist consists solely of the Hokuto Hyakuretsu Ken.
    • A certain take on Jam from Guilty Gear knocks the opposing character onto a bed and humps until their energy is drained, resulting in either a DKO or a victory.
    • The Killer Whale.
    • One of The_None's April Fools' Day releases, Noah, whose basic attacks - when low on health - would stamp you into the scene of Enter The Dragon to get promptly roundhouse kicked by Bruce Lee himself. No wonder The Nerd was right...
    • Gay Bahamut/Primeus, The God Of Retarded Characters by RicePigeon, most of whose attacks involve notoriously "retarded" characters.
    • There's also Giygas/Ozma, created by fhqwhgads7 and supposedly inspired by Primeus, which is an April-Fools'-joke-character-turned-boss. It's basically a gigantic floating jawbreaker that starts off with Giygas' attacks... and then imitates various Youtube Poop characters as it loses health and layers.
    • Vans' Rock Howard, who has the voice of Urien and whose MAX2 super move destroys the universe, crashing your program in the process.
    • Omega Tiger Woods, who can and will soundly pummel almost any character he comes across as long as that character isn't another Omega Tiger Woods. Where does he get that Shrimp Bus from, anyway? He's intended to be an SNK Boss-type character... just bizarre.
    • Similarly, Omega Tom Hanks, who turns the fight into a game of Bullet Hell by sending DVD covers of his hit movies after you.
    • Someone made a version of Mario for MUGEN called "NES Mario". He can only attack by jumping on enemies and he dies in two hits (if you don't press the button to turn into Super Mario again at the expense of some of the lifebar). However, there's something that makes him lethal: Fighting game characters flinch when hit, Mario does not. If you get a window of opportunity, you can just keep on stomping your foe and finish them off in less than a minute.
    • Speaking of Mario, someone remade the first level of Super Mario Bros. Your hilariously oversized character will still be one-shotted by Goomba and pits, especially if they have limited jump physics.
    • The creator who remade the first level of Super Mario Bros. also remade the first level of Super Mario Land and Contra. While the Super Mario Land stage is bit easier, prepare for your character to die in one hit in the Contra stage. Now the oversized character and limited jump physics makes the stage harder, depending on what character you choose.
    • Someone also made the classic version of Pac-Man. All he can do is move across the stage and munch on whatever gets in his way, but that's all he needs to do. God help you if he gets hold of a power pellet...
    • One of the characters used as a "cheapie-buster" in earlier times was the Metool, the Mascot Mook from Mega Man. It had half the attack and defense of a regular character (and died twice as fast), but it was short, making it hard to hit, could spam a Spread Shot from afar, and it could use its signature helmet guard. Oh, and that giant metool that instantly squished his enemy.
    • Saggot, aka Bootleg Sagat. An edited Sagat that plays like the infamous Street Fighter II bootlegs. What this means is a whole new level of Tiger Shot spam, ridiculous comboability, and he even crashes MUGEN on a regular basis. To further rub salt in the wound, his theme from Street Fighter 1 perpetually plays during his fights, overriding your music, and his victory pose references the famous Cornflakes line from the Street Fighter cartoon.
      • Other Street Fighter bootleg characters that end up being dangerous include Koryu (heavy projectile spamming much like the infamous Koryu edition), Broken (similar to Koryu), and Viga (whose moves can do serious damage).
    • Flame Hyenard. Just... Flame Hyenard. You WILL BURN! BURN! BURN TO THE GROUND! if you fight him.
    • Zeori and NM Ori, two entries in Trinity MUGEN's "Iori contest".
    • The Space Invader. The "Lethal" part comes from the fact that his laser is a One-Hit Kill, and the "Joke" part comes from the fact that it dies in one hit.
    • Iea. He flies off screen and dies if he gets hit, including his own assists. However, he has a lethal sword attack and can summon falling blocks that can one-shot opponents.
    • Winnie the Pooh. Specifically, the one from Winnie the Pooh's Home Run Derby. His baseball bat normally does pathetic damage, but if you time the attack as soon as he glows, it offs 1/3 of the opponent's maximum health or so. And it can't be blocked.
    • "Ms. Fanservice," who seems like a heavy edit of Yoko who uses other Ms. Fanservices for her moves, and an entirely different moveset. It sounds like a run-of-the-mill gag character, and is overall tamer than most characters on this list, but she has extremely aggressive AI, able to take down many other characters who aren't outright cheap. Including the original Yoko she was based on, who isn't a cakewalk herself.
    • NES Megaman plays like the NES classic games, obviously. More closely to Mega Man 2. Like the classic games, his Mega Buster does pitiful damage, his weapons have limited ammo and he lacks a slide, giving him poor mobility. Oddly enough, he doesn't have his Mercy Invincibility, taking more damage in the process. Oh, and despite having a power bar, he lacks any specials or hypers along with fragile defense. However, he makes up for this with his sheer small size, making it hard for opponents to hit him. The Metal Blades can shoot in 8 directions, making it useful as an anti-air move and has the most ammo. The Time Stopper while as useless as in the original game (made even more worthless as Mega Man cannot recharge his weapons here, making this a one-time use until next round) can be used to interrupt attacks or flee from combos, allowing Mega Man to free himself. But his deadliest weapon is the Air Shooter. Thought it was useless? Think again! Remember that trick against Crash Man where if you position the tornadoes right, Crash Man takes enormous damage? Here, it's even easier as most fighters are big enough for Mega Man to hit. If the opponent is not careful, Mega Man can unleash a flurry of tornadoes and can drain the foe's health within seconds.
  • Lethal Lava Land: Diablo's stage, among others.
  • Loads and Loads of Characters: There are so many characters out there to download and play with. The wiki itself lists somewhere around the range of over 2000 characters from all kinds of fighting games and miscellaneous media. Granted a large majority of them are Shotoclones and Sturgeon's Law is often in full effect when downloading certain characters.
  • Luck-Based Mission: Whether Bokosuka Wars wins or loses is purely luck, just like in the original game. It's also the only way he can give or receive damage. If he can't reach the enemy's hitbox (assuming the opponent even has one), if the opponent is immune to grapples, or if he fights himself, it will be a guaranteed draw game.

    M-O 
  • Samurai Shodown Konoha uses one in her Zetusmei Ougi.
  • Nintendo Hard:
    • A lot of AI patches go here. For a specific example, the work of Misobin_ISM. He turns mild mannered, but still challenging, characters into absolute monsters. His patch for Vergil basically pits you against an encyclopedia of his combos, Dio lays you out with some crazy tandems and abuses his teleport while defending, Geese will counter all of your moves and force feed you a Deadly Rave, and Shin Akuma is as insane as you would expect. There is also Hutano, who basically unlocks the true power within 9's Melty Blood characters and shows you some of the most nightmarishly evil combos ever seen.
    • Muteki's Guilty Gear characters are built with aggressive AI that takes full advantage of the computer's natural advantage against human players. It blocks most attacks without a second thought and links together very long strings of attacks and supers to make sure that the human player can't fight back for more than a second, and with Guilty Gear's extremely fast gameplay, tends to turn anything not incredibly fast-paced into chowder.
    • Any of the Cyberbots characters (Minus the Z-Akuma), have uneblievable AI.
    • For a non-fighting example, pitting fhqwhgads7's The Kid and Yukari Yakumo together will start the match with The Kid in a scrolling obstacle course. Keep in mind that like in the game, The Kid dies with one attack, and you can't fight Yukari unless you get through the course. Even then, the match simply becomes a boss fight against Yukari... and Primeus.
    • For a long, long time, Sander 71113's Wolverine was known as an absolute monster and the bog standard for players looking for a challenge.
  • No Ending: Most characters do not have ending storyboards for completing arcade mode. Or intros, for that matter.
  • No Fourth Wall:
    • In one of her winquotes, RicePigeon's Yukari Yakumo recognizes M.U.G.E.N as a computer program, and how amazing it is to merge diverse worlds together, then concludes that humans must really have been inspired by her.
    • In general, it's possible to edit winquotes, so any char can play this straight. For instance, there is a version of Rocko who comments that M.U.G.E.N. day can be a very dangerous day.
    • Unlimited Team's Deadpool has an hyper move where he grabs standard M.U.G.E.N. lifebars and powerbarsnote  and hit the opponent with them.
  • Nonstandard Character Design: If your roster contains characters from games with wildly different art styles, this is bound to happen.
  • Nostalgia Level: There's a few Bonus Level characters that do this.
  • Nuke 'em:
  • One-Hit Kill: Any character that possesses an extremely convenient one to use is almost always considered to be extremely cheap and/or a Lethal Joke Character. Examples include:
    • Rare Akuma's Shun Goku Satsu.
    • Many of the attacks that Chuck Norris uses, not just his Roundhouse Kick.
    • Each of Gulthor's ovepowered characters have at least TWO of these.
    • Killer Whale, Cheep Chomp, and Dopefish do this to your character if they eat him/her.
    • Oni-Miko-Zero does this to her opponent BEFORE THE BATTLE BEGINS.
    • Similar to her, Debugger does this to its opponent. Except that his works on pretty much everything (Oni-Miko-Z included).
    • Death Note: Light Yagami writes his opponent's name in his Death Note as soon as the match begins. Fans of the series can probably guess what happens next.
    • Zeeky H. Bomb has two of these. One (Random H-Bomb) only works as a counter, and the other (Zeeky Boogy Doog) severely damages Zeeky himself.
    • Pingu's most devastating attack has him sink into the ground as the lights go out and he calls to his opponent. Then, the lights turn on and he reappears in front of his opponent, wings upraised. Instant KO! His Shun Goku Satsu is usually a KO, too.
    • Master Mecha Sonic has "Hyper Kamehameha", which, while truly being 1 hit, actually does over 999 hits as far as the counter is concerned. Considering Mecha Sonic's record in Super Mario Bros. Z, this isn't exactly a surprise that he gets a move like this in Master form.
    • The Space Invader has this both ways. If his laser gets you, you're instantly vaporized. If you hit him once, he's instantly vaporized.
    • Andres Borghi's characters have Awesome, but Impractical one hit kills. They take 3 special bars and are blockable. In addition, in their original form they were Desperation Attacks only usable when very low on health, and the updated versions in the full game are finishing moves instead, only usable on an opponent who is low on health.
    • Noroko sends out a spectral version of herself forward. If this hits, she will fall to her knees and start crying, the opponent will come by to see what's wrong. and then a video plays where she either reveals her featureless face and reaches forward with a hand, or opens a disturbing-looking mouth and screeches. The opponent will immediately die, either of sheer fright or maybe having their soul stolen.
    • Peketo grabs then throws the opponent into a spiked wall, then decapitates (or just slashes) them with a knife.
    • Hashi grabs the opponent and feeds them some kind of seed that turns them green. Presumably that makes them taste better, for he then morphs into a huge Man-Eating Plant and devours the victim alive.
    • Ananzi/Viuda Negra throws the opponent into a huge web, turns into a Giant Spider and bites the opponent. Old version made the victim's guts messily explode. The new version is even worse: the victim starts coughing up small spiders and blood, then messily explodes, bursting in a shower of blood and a swarm of spiders.
    • Shar-Makai clenches the victim in its jaws, shakes it, throws it in the air and munches down again, completely pulverizing the victim.
    • Animus impales the opponent on a long rusty metal pole, rips the body in two, and showers him/herself with blood.
    • Reimu's Fantasy Heaven.
    • Gay Bahamut/Primeus has the Over Nine Thousand laser attack, when his power bar is full.
    • The Demon Wall instantly kills you if you don't defeat it in time.
    • Slot Machine has two: A clone of the Shun Goku Satsu from rolling Toadma), and a lazer beam that goes across the top of the screen from hitting Quick Man until after either the match ends or the machine is defeated in a team-like mode like survival or... a team. (The beam stays at the top of the screen even in later rounds.)
    • Hastur and Hige both are LOADED with these...
    • Some versions of Homer's "Riot of The Beer" gives him OHKO moves such as "Touch of Death", "Road Roller D'oh", and Shun "Homer" Satsu aka "Raging Doughnut."
    • Basara-kun's Dalek has a Death Ray as its only attack being accurate to Doctor Who series, as the attack name says. Made with a purpose as a Lethal Joke Character, by the way.
    • The most dangerous one hit kills however come from null spammers and other system exploiters. They don't need to fight you as they already One-Hit Kill you before the match even starts. In fact, there's a certain type of system exploiter cheapie that doesn't just one-shot the other fighter... it can one-shot the engine itself, and possibly even your computer!
  • One-Hit-Point Wonder:
    • The Kid from I Wanna Be the Guy. Complete with blood spatter and GAME OVER. PRESS "R" TO TRY AGAIN.
    • Subverted in later versions where he gains super armor while facing himself.
    • The Space Invader is destroyed in one hit, but its laser is a lethal attack.
    • Flappy Bird. If he gets hit even once or if he touches the ground, he's toast. If he uses his Limit Break and bumps into any of the pipes, he's also toast.
  • Overly Long Fighting Animation: Many a One-Hit Kill, but special mention goes to GaoGaiGar's Goldion Hammer, which has a one-minute-long animation.

    P-R 

    S-U 
  • The Sandbag:
    • The Trope Namer, made by gncmario, is a character. However, it can't be controlled.
    • This also makes it the ultimate of Joke Characters.
  • Schizophrenic Difficulty: In addition to the Lethal Joke Characters covered above, there are several characters, or at least versions of characters, who are much harder or easier to take on than you would think. For instance, Alucard's AI is pretty easy, but Team S.M.R.T's Homer Simpson can be a tough fighter, especially if he enters Riot of The Beer Mode. That's not getting into games with extremely different mechanics and pace, such as trying to pit 90s-era fighters with little combos against, say, Guilty Gear characters.
  • Shape Shifter:
    • The_None released a version of Kishima Kouma dubbed "Shadow Kouma" that at first appears to be a perfectly innocent custom take on the character. Then you actually see him in action and he turns out to be a Shang Tsung type fighter who transforms into every character The_None has created for his attacks. He does have a handful of unique moves, including a team up with Ralf Jones and JoJo style tandem attacks.
    • Before that, there was Cerenas's Sihon (who transforms into various Samurai Shodown characters) and the collaboration between Andre Lopes and Ryan Kerns in the form of Mugena (who mainly transforms into various female characters).
    • Shang Tsung himself as well. OMEGAPSYCHO's version deserves special mention, as he managed to make him able to transform into nearly every MK1 character but Goro. Juano's Shang Tsung goes this way too, having every MK 2 character, including Jade, Noob Saibot and Smoke, but excluding all bosses.
  • Shotoclone:
  • Shout-Out:
    • Kamek is loaded with them. He can summon one of three Pokémon at will and can use fatalities, one of which is directly based on one of Smoke's. His Troopa Rush super is admitted in his readme to be a takeoff of Tron Bonne's Lunch Rush special. Some of the objects that can fall from the sky in his Switchblock Drop super are the Egg-o-matic, the Master Emerald, a cow, and Lavos. And he can use Ultima.
    • Numerous characters use Mortal Kombat-esque fatalities or otherwise incorporate something from the game, such as Most_Mysterious's Dink Smallwood speaking some of Shao Khan's lines, or the "Shao Mario" from Slot Machine, which is Mario's Super Mario World-appearance given Shao's voice.
  • Showy Invincible Hero: The players who make MUGEN videos on YouTube.
  • Silliness Switch:
  • Situational Sword: It's possible to code attacks that can only hit in certain situations. Examples are: If the opponent is in the hit state note , if the opponent is not in the hit statenote , if the opponent has been hit by a certain previous attack note , if the opponent was not hit by a certain attack note , and so on and so forth.
  • SNK Boss:
    • Depending on the creator, the AI can be written in such a way that SNK bosses or any normal character can turn this trope Up to Eleven.
    • Every Mortal Kombat boss from the 2-D games are in there too. And that includes Motaro.
    • Akame counts as well (when computer-controlled, of course). Due to her advanced AI, she's quick to pull off her moves, and she reads you like a book, meaning she can block many of your own moves and counter with her "Barrier Burst." Some of her specials can even KO you instantly!
  • Some Dexterity Required: Tends to occur as a reflection of the source game (e.g., "The Pretzel", the Fan Nickname for Geese Howard's Raging Storm command), although editing the files to change the command to something easier is a simple matter.
  • Stylistic Suck:
    • Kung Fu Man's intro and ending storyboards that come with the engine by default qualify, looking like a kid's crayon drawings.
    • Most_Mysterious's (of Omega Tiger Woods (in)fame) entire creationhood can be basically summed up as this.
    • The Dancing Banana also counts in a way, what with being a rather pixelized character, but the reason for this is because his graphics are based off the original emoticon.
  • Summon Magic: Some characters do this as a super attack by calling in a reinforcement to perform an assist (see Kamek in the Shout-Out entry above). For example, Hatsune Miku takes this Up to Eleven with her super singing attacks - if she sings a soundtrack from a well known franchise, a character from the franchise comes in to perform the assist. And given how many there are...
  • Super Move Portrait Attack: The_None's Shadow Kouma deserves special mention, for that he has a super move that takes this trope literally. Yup, the said move involves the portrait itself hitting the opponent.
  • Stone Wall: Frost Man fits this bill. As mentioned, he has permanent super armor, making him Immune to Flinching indefinitely. He can take hits like there's no tomorrow, cannot be combo onto, be thrown or be stunned. Combine with high health/defense, he is a durable and an unstoppable tank. However, he has limited attacks, said attacks does pretty weak damage (exceptions are his hyper moves of course) and lacks good combos. It's also possible that few characters may break his super armor if they possess certain counter moves.
    • Plant Man from Mega Man 6 has a Power Battle version where his Plant Barrier makes him immune to all attacks! The trade off is that his buster (seed?) shot takes about a second to activate and can shoot one at a time. Said shot does pretty weak damage. He can still use his shield to attack, but that will lose his invulnerability.
  • Swiss Army Weapon: Most of 3ha's characters have custom modes based of completely unrelated characters. Among examples:
  • Tag Team: An undocumented code exists (called TagIn) that allows a character to change their state as well as that of the partner's. Naturally, this can be used for a Tag Team function as well as a Switch Out Move.
  • Take That:
    • Rare Akuma is the mother of all Take Thats to badly done "Shin", "Orochi" and "Evil" edits of many characters. He has an abundance of special effects, is effectively immortal, and can kill most characters in the space of a few seconds.
    • There's an entire full game being made with nothing but Akumas with completely different movesets. The creator of the project, Basara-kun, admitted he's doing it because he's sick of all the Akumas going around.
    • Rikard's most prolific creation is Slightly Pissed Off Ryu, a parody of the various Shin, Evil, Orochi, Violent and Holy Ryu edits on the internet. Rikard's "story" basically sets Ryu as a McDonald's bum, depressed and physically out of shape after finding his wife Sakura cheating on him with Akuma (he has appropriate, and hilarious, victory and winquotes against both of them). His Hadokens are usually a pathetic short range burst, his Shinku Hadoken may u-turn RIGHT BACK INTO RYU'S FACE, he falls flat on his back after a Shoryuken, he sometimes breaks his ankle when he does his trademark Hurricane Kick, and one of his other attacks has him lobbing either a McDonald's meal or M. Bison's corpse at them. Most Ryus run on graphics over gameplay. This Ryu? Runs on pure Rule of Funny.
    • P.o.t.S released Bison...literally. It's an actual bison with M. Bison's cap on its head. It uses distorted versions of Norio Wakamoto's voice clips from Capcom VS. SNK 2 as well as clips from the Animated Adaptation. And it's actually balanced to be fought as a boss character, having high stamina, infinite prevention measures, and a very good AI that takes advantage of the character's high power. Instead of being a Take That to cheap characters as Rare Akuma was, it's a Take That to joke characters and serious characters, simply by existing. Hilarity did indeed ensue.
    • Arpa's Casual Evil Ryu is a big yet sly Take That to Infinity Mugen Team's "Eternity of Heroes" character template and its many, many flaws, amongst other things. He outright states as such in his True Readme...which is written in Saurian and also features a Take That to that game.
  • There Is No Kill Like Overkill: Anything involving lots and lots of blood, characters with lots of flashy effects, and any attacks that reach the 999 combo limit. Ironcommando is pretty much a top contender if not outright the Overkill Overlord. Once he became much less egotistical and willing to listen to feedback, he stopped adhering so strictly to the trope.
  • Time-Limit Boss: Yee (yes that one) is essentially this, since each time Peek finishes his song, Oro's head will pop in as an unblockable, fullscreen attack that will kill most characters within four hits.
  • Trope Overdosed: Since it is a crossover of every fighting game in existence, this was bound to happen eventually.
  • Unexpected Gameplay Change: It's theoretically possible to port any character from any game, not necessarily fighting games, so this is the result if the chars are ported with their source mechanics. For instance, there are versions of Marisa and Patchouli, using their Mega Mari sprites and gameplay, with any of these the game feels more platform-like.
  • Unwinnable by Design: Any fight against Oni-Miko-Zero. Or Debugger (if he is on P1's side).

    V-Z 
  • Video Game Cruelty Potential: Certain characters can attack or KO their opponents in rather gruesome ways if you activate their special moves, hyper moves or fatalities. This has to be expected for Mortal Kombat, Samurai Shodown, Black Heart fighters or any other characters with similar brutal and gory moves.
  • Video Game Perversity Potential: Considering that most of the fighters and stages are fan-made content, this is bound to happen. There are many NSFW fighters that have either questionable sprites and attacks and there are stages that have a rather...dirty feel to them.
  • Virtual Training Simulation: One of the two stages included in the game is the "Training Room", which is based off these.
  • Widget Series:
  • Wolfpack Boss:
    • There is an AI-only character called "Biohazard" that is basically a huge swarm of zombies, crows and dogs that all share one life bar, and killing enough of them eventually summons a Tyrant. The Alien Queen's default palette is also this; she does not appear at all in this mode, but instead sends a swarm of Alien drones to attack you, and the match only ends when you've taken them all out. The Mad Gear Gang are also available as an opponent.
    • There's also the "Strength Training" minigame, which pits your character against a swarm of Beat 'em Up-style Mooks, and is sometimes used by series creators for mook fights.
    • With some luck, you can hack stages like Super Mario as an opponent, resulting in an odd variant of this.
    • An experienced coder can code this onto any character, making that character attack in a Zerg Rush of easily-defeated clones. A good example and possibly the Codifier of this would be Most_Mysterious' Rox Howard Clones.
    • There's also a Famicom Wars character. You fight tanks and infantry, and then a Tennis Boss in the second round.
    • There's also a Saibamen character made by The_None, where you fight against three AI-controlled Saibamen.
    • The Toa Mata can be sort of like this. Toa Tahu is always the first Toa out, and as such is the only one who needs to survive, but there is a special mode for the team that gives them infinite meter, and all the Toa are on the field at the start in that mode.
  • You Gotta Have Blue Hair: MUGEN allows color/palette customization, so this trope is there in spades, especially for characters based on Anime.


Alternative Title(s): MUGEN
