An aquatic esper that inhabits Lake Dorr in southern Olderion. The locals worship it as a water god. Thanks to the purified water that Leviathan produces which has the power to ward off monsters, Olderion was able to prosper in peace without fear of attack. However, Veritas of the Water hatched a plan to drive Leviathan mad, after which it appeared before Rain and the gang ready to fight.
