The Dark Ton Ton is an enemy from Final Fantasy Crystal Chronicles: Ring of Fates. It fights identical to the Dark Skeleton, and thus should be treated as one despite is increased stats. It is fought in the area where the Death Lich was fought, if the player had defeated it, and is flanked by two Dark Skeletons. Upon defeat, it will drop the same spoils as the Death Lich.
It is easily identified by its increased size compared to the other enemies in the area. Of note, Dark Ton Ton has a -10 weakness to Holy elemental attacks.
