The King Bomb is a giant Bob-omb and an enemy from Super Mario RPG. It appears in Bowser's fortress during the boss fight against Magikoopa.
During the fight, Magikoopa will summon King Bombs to aid him. The King Bombs have no attacks other than their Big Bang spell, in which they charge at Mario and his party and explode, dealing massive damage. The player must defeat the King Bombs first before they decide to detonate. They are most vulnerable to Mario's jump and fire attacks.
