The Boss Bomb is an enemy from Final Fantasy Crystal Chronicles: Ring of Fates. It fights identical to the Ice Bombs and should be handled as a regular Ice Bomb despite its increased stats. It is fought in the area where the Garuda would be fought if the player has already defeated it, and is flanked by two Ice Bombs. Upon defeat, it will drop the same spoils as the Garuda.
It is easily identified by it being much larger than the other enemies in the area.
