Mewtwo's Skins:
- Mewtwo's orange skin is based off his colors in Pokemon Yellow and his alternate trophy in Smash 3DS has a pose that copies the sprite.
- Mewtwo's dark color scheme copies Shadow Lugia's color scheme.
- Mewtwo's side B (Confusion) gives Mewtwo enough horizontal distance after almost running off the platform in Battlefield to jump to the other platform.
- Disable (down B) only works when the opponent is facing Mewtwo.
- Mewtwo's neutral B only deals damage when it is released.
- Mewtwo's Up special can never lead him to go straight down but rather at an angle forward or backward.
- Using the custom move glitch Mewtwo's side special 2 can alter his standard up B as long as you use that side special.
- Some customs are different from 3DS and Wii U.
