''Kart Fighter'' is a bootleg (read: {{unlicensed|Game}}) two-player FightingGame made for the UsefulNotes/NintendoEntertainmentSystem by Hummer Team. Predating ''VideoGame/SuperSmashBros'' by six years, it's basically Mario characters (from ''VideoGame/SuperMarioKart'') beating each other up ''Franchise/StreetFighter''-style in one of the first NES fighting games. Each character has up to three command moves that allow for more damaging moves.

For a bootleg NES game, it's actually a surprisingly good effort, being one of the best 2D fighting games for the console alongside the officially-made ''Videogame/JoyMechFight'' (and the bigger amount of ''VideoGame/StreetFighterII'' feeling you'll ever get on a NES game).

* Mario (spelled "Mari")
* Luigi
* Yoshi ("Yossy")
* Toad ("Kinopio")
* Peach
* Donkey Kong Jr. ("Donkey")
* Bowser ("Koopa")
* A Koopa Troopa ("Nokonoko")
!!This game provides examples of:
* BananaPeel: Donkey Kong Jr.'s projectile attack is a thrown banana peel. Naturally, it makes the opponent trip (and does quite a bit of damage).
* BlindIdiotTranslation: Mostly averted with the character names, since they're based off the Japanese ones[[note]]"Yossy" is a different transliteration of ''Yosshii'', which is how "Yoshi" is written in Japanese[[/note]], with the exception of Mari(o).
* BubblyClouds: Peach's stage.
* TheComputerIsACheatingBastard: Luigi. Most of his specials are AI only and can't be done by the player.
* DummiedOut: The game contains graphics for a GameOver screen, which ended up being unused and replaced by the high score screen.Some character sprites within the game data are also unused.
* EasyModeMockery: You only get an ending screen if you beat the game on the highest difficulty setting. The rest of the time, you get a high score screen and that's it.
* EndlessGame: Averted. While many assume that the game repeats the last two fights endlessly (against Koopa and a clone of your character), the game ends after the second loop.
* EverythingsBetterWithMonkeys: Donkey Kong Jr.
* EverythingsBetterWithSpinning: Peach and Donkey Kong Jr. have a spinning charge move, Mario and Luigi spin when doing their uppercut, and Koopa Troopa has a shell spin move.
* {{Fanservice}}: Why Peach has such a short skirt is either this or technical limitations.
* ImmuneToFlinching: [[SecretAIMoves A.I. Luigi]] during his Green Missile Kick.
* JokeCharacter: Koopa Troopa arguably qualifies, due to being the first opponent in 1-Player mode and having two special moves instead of three, none of which are projectiles. Luigi ends up being an unintentional example due to a glitch.
* KamehameHadoken: All of the characters have at least one projectile move, minus Koopa Troopa.
* LethalLavaLand: The Mario Bros.' stage.
* TheLostWoods: Toad's stage.
* MirrorMatch: The final boss. Can also occur in two-player mode.
* MovesetClone: Mari(o) and Luigi. They have the same moves, but the difference is that most of Luigi's specials are SecretAIMoves.
* NoEnding: Finishing the game on any difficulty other than the highest has the game simply end with the high score screen.
* PrehensileHair: Peach.
* RecycledSoundtrack: Donkey Kong Jr.'s theme is a slightly altered version of the boss theme from ''[[http://bootleggames.wikia.com/wiki/Jing_Ke_Xin_Zhuan Jing Ke Xin Zhuan]]'', while the ending theme ended up being used in several of Hummer Team's other fighting games.
* SecretAIMoves: Most of Luigi's special attacks are only usable by the AI.
* ShiftingSandLand: Home of Koopa Troopa and Bowser.
* {{Shotoclone}}: Mari(o) and Luigi, both of whom come with hadouken and {{shoryuken}} moves.
* {{Shoryuken}}: Used by many of the characters.
* SNKBoss: Every single AI-controlled opponent after the first. They are able to read your movements and will use attacks to counter yours, and will even change strategies after being beaten once. This usually makes them hard to fight, [[AIBreaker unless the player spams blocking and low kicks]].
* SomeDexterityRequired: This game actually has command moves, but thankfully they aren't hard to execute.
* [[SpellMyNameWithAnS Spell My Name without an O]]: MARI, a mistranslation of Mario.
* TailSlap: Yoshi does this instead of kicking.
* TookALevelInBadass: Yoshi, Peach, Toad, and Koopa Troopa. No longer mounts/distressed damsels/advisors/cannon fodder anymore. Yoshi is one of the more competent fighters and his AI ''will'' kick your ass if you don't know how to counter him.
* TurtlePower: Bowser and Koopa Troopa.
* WaifFu: [[DamselInDistress Peach]] can actually kick some ass.
* WarmupBoss: Your first opponent, Koopa Troopa. His shell spin special is pretty weak, and he has no far range attacks. As for [[SNKBoss the rest of your opponents]], they're tough.
* AWinnerIsYou: Beating the game on the highest difficulty gives you a win screen.
* YourSizeMayVary: Bowser. He's actually the ''smallest'' character in the game, even though he's larger everywhere else.
