Big Bang (move)

Big Bang is a special attack used by a King Bomb from Super Mario RPG: Legend of the Seven Stars. It is capable of dealing a lot of damage to Mario and his allies, so they should try to defeat the King Bomb before it explodes on them.

Coincidentally, Big Bang is also the name of a similar attack in Square Enix's Final Fantasy games. It is used by Zeromus, and can deal a large amount of damage to all of the player's party.
