Bowser Bomb is the B-Down move of Bowser in his Melee appearance and also Bowser in his Brawl appearance. If Bowser is in midair when using this move, he slams to the ground with a butt-stomp. If he's on the ground doing this, he will leap forward diagonally before performing the butt-stomp.
This special attack is shared by Giga Bowser, both in his boss appearance in Melee and in his playable appearance in Brawl.
The move is based on Bowser's attack pattern in Super Mario Bros. 3 Template:Mario Melee
