Ultimaton, also known as Weapon XV, is a supervillain in the Marvel Universe and enemy of the X-Men. Ultimaton first appeared in "New X-Men" #143 (August, 2003) and was created by Grant Morrison and Chris Bachalo.

Fictional character biography

Ultimaton is the latest living weapon created by Weapon Plus, the anti-mutant supersoldier program that created Captain America, Wolverine and Fantomex, and was designated by his creators as Weapon XV. Like Fantomex (Weapon XIII) and Huntsman, Ultimaton was born and was artificially "evolved" in "The World", a man-made environment designed to create super-soldiers using Sentinel technology. Due to the time manipulation capabilities of the World facilities, Ultimaton was several generations more advanced than the preceding living weapons.

Ultimaton was created to be the powerhouse of the Super-Sentinels, a team of mutant hunters conceived by John Sublime as a publicity stunt to make the extermination of mutants acceptable to the public. Fantomex and Huntsman were intended to be his teammates, but Huntsman had been destroyed and Fantomex had gone rogue.

Ultimaton was released from the World when the facilities were attacked by agents of Advanced Idea Mechanics, who wanted to recoup the technology Weapon Plus had stolen from them. Ultimaton wiped out the attackers and later fought Wolverine, Fantomex and Cyclops and escaped to the Super-Sentinels orbiting base, constructed in a remnant of Asteroid M. At this point, Ultimaton had begun to wonder about his purpose in life, questioning his fate of being a mutant-hunting killing machine.

Fantomex, Wolverine and Cyclops followed Ultimaton to the space station, where Fantomex and Cyclops fought Weapon Plus agents. Wolverine denied Ultimaton's claims that he could have been a painter before destroying the space station. In "The New X-men #148", Wolverine later tells Jean about how he finished off Ultimaton right after the explosion, while it was contemplating the purpose of its own existence, and wasn't paying attention.

Trivia

* Ultimaton wondering if he could've been a painter is a reference to Adolf Hitler, himself an amateur painter.
* Ultimaton's name is a portmanteau of the words "ultimate" and "automaton". The name also suggests links to the word "ultimatum".
