Big Bang is a move used only by King Bob-omb in the game Super Mario RPG: Legend of the Seven Stars. It is only seen and used in the battle with Magikoopa in Bowser's Keep.
With Big Bang, the King Bob-omb explodes leaving a massive explosion that deals very high damage to all of Mario's team. It is highly recommended to take down the King Bob-omb before it uses this move.
