Ultimate Chimera

The Ultimate Chimera (Japanese: きゅうきょくキマイラ Ultimate Chimera) is a giant, pink Chimera of no defined species, with a small bird on its head, first found in the Chimera Laboratory and later residing in the Empire Pork Building. It is found in Mother 3 and Super Smash Bros. Brawl.

In Mother 3, it was part of the Chimera project. The Ultimate Chimera was created by Dr. Andonuts in the Chimera Laboratory to be the ultimate killing machine, but it went rogue before he could destroy its last weakness, an off-button on its back. Due to Salsa letting it out of its cage, however, it escaped from the labs. Contact with the Ultimate Chimera is fatal and an automatic game over. It cannot be battled, and because of this, it has no real stats. Its only weakness is that it is battery powered, and has an on/off switch on its back, however, there is no way of pressing this button as Lucas.

In the Chimera Laboratory, it stalks the narrow hallways and small rooms, and there is no way to tell which room it is currently in. There is a split second chance to run away if it spots you, however. When it spots Lucas, a yellow exclamation mark appears atop its head and a high pitched ping sounds, charging at him at a fast speed. When it changes rooms, a loud clang is heard as it moves, which is a helpful sign for Lucas if he is trapped in a room.

In the Empire Porky Building, however, the Chimera is in one of the bathrooms in the bathroom maze. If Lucas knocks on the door, he'll hear the familiar "Ping!". If he knocks again, he charges the door repeatedly, breaking the lock and granting him access. In this room, a single present is inside, although Lucas has only a brief moment to run back into the hallway, and lure the Ultimate Chimera out of the room to obtain the present.

In Super Smash Bros. Brawl
It randomly appears on the New Pork City stage. If any fighter is unfortunate enough to get in its path, they get hit with over 300% damage and sent flying, almost always resulting in a KO. It is possible to temporarily defeat the Ultimate Chimera by smashing the breakable platform at the bottom of the stage while it is standing on it, however. If the player succeeds, it lets out a roar as it falls to its death. It will, however, still re-spawn later. The off button on its back is non-functioning.
