The Ultimate Chimera is a hazard in New Pork City. Appearing randomly in any part of the stage, it walks slowly and its bite attack results in a One-hit KO and deals about 100% or 200% damage each bite. The Ultimate Chimera can only be defeated by destroying the makeshift bridge platform at the lower center of the stage when it walks over it.

In Mother 3

In Mother 3, The Ultimate Chimera is first seen in a factory in a forest(in chapter 7) then appears in the New Port City building (in chapter 8)When it sees or is near Lucas's party, it will pursue them. Engaging it in battle is useless as it will kill the party in one hit when it is engaged. The Ultimate Chimera still has an "off" button on his back, but it does nothing.
