Fake Wario

The Fake Wario is the second-to-last boss in the NES version of the game Wario's Woods. He looks exactly like the "real McCoy", but is actually simply a convincing fake. He has the power to make one whole row of mixed enemies fall. After killing the boss, Wario pretends to be dead, but quickly leaps up again and informs Toad that the Wario he defeated was a fake, and the real on is "ready to rumble!" Toad must then clear 30 more rounds before fighting the "real" Wario.
