Ultimate Chimera

The Ultimate Chimera (Japanese:  Ultimate Chimera) is a giant red chimera with a small yellow bird on top of it that was created in the Chimera Laboratory in the Murasaki Forest. It is described as a deadly monater that will stalk and murder its victims with its razor sharp teeth, it is so powerful and dangerous that there is no way to defeat it, with those who encounter it have fleeing as their only choice of survival.

It appears in Mother 3 first appearing in the Chimera Laboratory and later in the Empire Porky Building, it also appears in the series starting with Super Smash Bros. Brawl.

In Mother 3
The Ultimate Chimera was part of the Chimera project and was created by Dr. Andonuts, who was forced to work for the Pigmasks against his will, in the Chimera Laboratory. It was designed to be the ultimate killing machine, however Salsa let it out of its cage allowing it to run rampart throughout the lab and terrorize the workers before it's last weakness was removed, the off-button on its back. Unlike other enemies, contact with the Ultimate Chimera does not start a battle, instead it is fatal and results in an automatic game over. Because it can't be battled, 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 makes it's first appearence after Lucas and Boney (and possibly Duster) defeat the Almost Mecha-Lion. The Pigmasks enter a state of emergency when they realize the Ultimate Chimera has still not been contained, and is wandering throughout the lab. The Pigmasks warn Lucas (disguised as a Pigmask) about how big the threat is, saying that should he encounter the monster to run away no matter what.

From here 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 the party, 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.

Once Lucas and Boney corner Salsa and Samba, the Ultimate Chimera also corners them causing Lucas and Boney to flee. While trying to stay alive, Dr Andonuts informs that it is battery operated, and its only weakness is the off button they were unable to remove. Salsa rushes in just as it's about to attack Lucas and Boney, and presses the button incapitating the monster.

After Lucas and co. leave, the yellow bird steps on the button and reactivated the Ultimate Chimera, then it escapes into the wild and makes it's way to New Pork City.

The Chimera reappears in the Empire Porky Building, 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.

A white board in the Chimera Laboratory states that if the Chimera escapes, they are to seal all entrances and exits immediately. In addition to this, if the Chimera is to escape outside, they are to feign ignorance. The protocol for if it is seen by civilians had been erased, however.

In terms of species, the Ultimate Chimera's origins are left unknown. A chimera is a physical or DNA fusion of different species that are usually easily definable. This is reflected on all of the chimeras found throughout Mother 3, however the exception is the Ultimate Chimera: it's appearence has no actual visable traits of any species. Appearence wise, it is a giant red monster with purple wings and an orange pointed tail, none of which visibly belong to any animal. While it is battery operated, it's physical appearence suggest it to be an organic being that doesn't appear to be fully or partially robotic (further supported by its Smash Bros. models), granted that if it were one it would be a robot or a cyborg and not a chimera, although it could be bio-organic. Overall rather than being a combination of two species, its design appears to be the result of toying with DNA resulting in the creation of a mutant monster.

In the Super Smash Bros. series
The Ultimate Chimera makes an appearance on the New Pork City stage in both Brawl and Ultimate. If any fighter is unfortunate enough to get in its path, they get hit with 200% if bitten and 300% damage if the person gets trapped inside it and is 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; if the player succeeds, it lets out a roar as it falls to its death. It will, however, respawn later. The off button on its back is non-functioning.

In Super Smash Bros. for Wii U the Ultimate Chimera appears as a Smash Tour item. When selected before a battle, it causes the user to take two fighters instead of just one from the last opponent they KO.

In Super Smash Bros. Ultimate it is once again a Stage Hazard in New Pork City dealing 100% damage when it bites. Unlike in Brawl, it no longer launches fighers at high speed, instead when it bites it will instantly KO the fighter reguardless of their percentage. The Ultimate Cimera also appears as a spirit.

Super Smash Bros. for Wii U

 * ''If you ever find yourself faced with this thing, run! There isn't enough time to stop and wonder what two creatures were combined to make this! It's so insanely out of control, even the people at the Chimera Laboratory wish they'd never made it. Eek!
