Giga Bowser (ギガクッパ, Giga Koopa), is the gargantuan and powered-up version of Bowser. He first appeared as the hidden final boss in Super Smash Bros. Melee's Adventure Mode and as one of the final opponents the player must face in Event Mode. He eventually made his semi-playable debut in Super Smash Bros. Brawl as Bowser's Final Smash. Having debuted in the Super Smash Bros. series, Giga Bowser is considered a part of the Super Smash Bros. universe, even though the character he is based on, Bowser, is from the Mario universe.
