Bowser (Super Smash Flash 2)

Bowser is a playable veteran starter character in Super Smash Flash 2. He was originally shown during the initial planning phases of the game, going through several different design iterations before finally resurging after being revealed at the end of the second McLeodGaming Direct. Bowser's sprite design, moveset and voice clips come directly from Super Smash Bros. Brawl. His color and dash animation come from Super Smash Bros. for Nintendo 3DS and Wii U.
