Featuring sprites and moves based on its Super Smash Bros. counterpart, Mewtwo is a quick and floaty character that can rack up heavy damage through extensive and rather easy to pull off combos. The character features a similar mechanic to the Final Arm gauge from the creator's own Eeveelution characters, being able to activate one of two one-hit K.O. attacks once it's filled up, complete with cinematics and background music.
Mewtwo plays in a six-button style that uses (X), (Y), and (Z) as Normals and (B) as a projectile button. For some reason, Mewtwo also uses (A) and (C) for commands and nothing else. The (A) for a shield and (C) for a forward hop. No extra attacks, nothing. The gameplay style is extremely similar to Marvel vs. Capcom, being able to chain all Normals into each other, Specials and even Hypers. The combos are satisfyingly easy to perform, even creating infinites with some moves. Mewtwo also features a double jump, but that doesn't help much. All of Mewtwo's projectiles use an energy meter at the bottom.
His moves require combos in order to do significant damage. His floatiness and mobility are emulated straight from Super Smash Bros. The worst part about Mewtwo in battle is his A.I.
Mewtwo does not feature a custom A.I. Mewtwo's always at a disadvantage and is forced to block at all times, and rarely does anything else.

This character's movelist is in a language other than English. English translations for attack names can be viewed by hovering the mouse cursor over the non-english text.
This character does not have any victory quotes, meaning it uses the screenpack's default.
Sprites of the creator's own Flareon character can be found within Mewtwo's sprite file, though they go unused; it is likely that Flareon was used as the base character from which Mewtwo was built upon.
