Ultimaton (Earth-616)

Ultimaton was a 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.^[1][2]

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 recuperate 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, and killed Ultimaton by detonating a bomb.^[3]

Ultimaton was later resurrected in The World and tasked by Fantomex with guarding a hidden chamber which held a child Apocalypse clone created from a blood sample taken from the one previously executed on the Celestial Ship.^[4]

After Evan joined the Jean Grey School for Higher Learning, Ultimaton's function becomes supporting X-Force.^[5]

After Fantomex's death, Ultimaton reverted to its primary function, which was killing mutants. He murdered Gateway and detonated, destroying Cavern-X.^[6]

Ultimaton was later revived in The World and under Fantomex's control once more.^[7]
