Just like in the original game, the goal here is to hit as many ducks as possible to reach a high-score, but instead of using a gun you will have to use your chosen character to hit them using any moves you want ranging from your regular jabs to super beams, this also includes throws.

Yami was only put in Tatsunoko Vs. Capcom so Capcom could have a multi-phased boss, which makes its ball form look incredibly stupid. This is an adaptation of the first phase, and the first phase only.

This version of Skullman fights solely in his X-form, the form that fights like a regular character. You're welcome.

Just your typical Reisen. Plays like your typical Touhou character.

This version of Konata hails from Lucky Fighter II, a Lucky Star version of Super Gem Fighters Mini Mix aka Pocket Fighter. She plays pretty accurate to her source game.

Like the original stage, you must guide your character (supported by Tails's biplane) to the end of the stage while avoiding flying badniks. Collect rings along the way to avoid being knocked out by the badniks. The stage is more difficult to play when playing as a large character.

The objective of Catwalk is to hit the buttons that appear on screen at the right time; that being when the buttons overlap the green line at the top of the screen. If the player misses a button press or presses the wrong button, they will lose some life. Life can be slowly regained by hitting a string of buttons, known as a "chain" in-game (not to be confused with chain attacks). The player must survive for a given period of time as indicated by the "TIME" bar at the top of the screen; this defaults to 60 seconds.
Due to technical limitations, Catwalk's note chart does not map to any particular song or stage, nor does the character come with music. This also means the chart's length is determined by a timer rather than the length of a given song, and is charted semi-procedurally. The chart's speed starts at a default rate, but increases for every chain of 50 notes successfully hit. If a player breaks their chain, the speed reverts back to the default.
Catwalk has a configuration file, CONFIG.txt, which contains a few options that can be adjusted to make the game easier or harder. BASE SPEED is the default speed of the chart, Use X Y Z toggles whether or not to include the X, Y, or Z buttons in the chart, PENALTIES ON/OFF toggles whether the player should be punished for pressing the wrong button, ARROWS POSITION aligns the directional button icons to the left-hand side of the chart, and KEY LIMIT limits the number of notes that can appear simultaneously.

In this bonus game, the player has to fight as many enemies as possible before time runs out.

One of the newest characters from Nijikaku
Based on a Futaba Channel meme from 2018.  Like Mukuro, he has a tendency to unleash assists that will harm both the opponent and himself.  However, unlike Mukuro, assists will come out automatically.  Be wary of the spinning cat head in the corner.  When it turns red, watch for the exclamation point to avoid getting hit by your own attack!

A Rick Taylor that is a lot more accurate to the games than you'd think.

Easily the most iconic Kamen Rider character in M.U.G.E.N.  Was surprised this wasn't uploaded already.

Pooch was created by the Walter Lantz Studio as one of the many rivals to Mickey back in the 30s. He served as the predecessor to characters like Andy Panda, Chilly Willy, and of course Woody Woodpecker. This guy seems to be Crowsar's favorite of the 30s cartoon stars.
By Crowsar
 

Not the earliest cartoon character, but definitely the most famous of the pre-30s era of cartoons.  He's been in cartoons since 1919, back when he was named "Master Tom", and went on to star in many shorts and TV shows up to the early 2000s.  This version of Felix is based on his NES game, which came out a few years after his failure of a motion picture, and a few years before his best series, The Twisted Tales of Felix the Cat.
