Giga Bowser

Giga Bowser is a giant, monstrous form of Bowser who is the primary antagonist in Super Smash Bros. Melee. He may be fought in the game under a few circumstances such as replacing Bowser as the boss of Adventure mode in Normal mode or harder and in several Event matches. He is probably one of the most powerful character in the game. His attacks are the same as Bowser's but are stronger and have side-effects such as the Whirling Fortress (Bowser's B+Up Move) can freeze your character. He's even the slowest character because his speed is double the slow speed of Bowser. He cannot be grabbed and thrown out of the battlefield.
