[6] In July 2013, Marvel announced the character's first solo series, Fantomex MAX, written by Andrew Hope, and illustrated by Shawn Crystal.

[citation needed] Fantomex then made sporadic guest appearances with the X-Men until October 2010 when he has a permanent member of the new Uncanny X-Force with Rick Remender and Jerome Opeña as the creative team.

Like the rest of his people, he is born and raised in the World, a man-made environment designed to create super-sentinels, media-friendly mutant-hunters modeled after Saturday morning cartoons.

Although his nationality is technically British as the World is located in England, Fantomex later claims he was raised in a virtual France with imperfect programming.

In fact, he tells the two that he has stolen sensitive information about the Weapon Plus project while in the Channel Tunnel, and offers to sell it to Professor Xavier for $1 billion.

Knowing that those who have fallen prey to Weapon XII's influence are lost, Fantomex kills Darkstar and all others who are mentally connected to the creature.

Fantomex later travels to Afghanistan in an attempt to steal a list of the world's richest mutant slaver traders, the names on which he intends to blackmail.

Fantomex, Wolverine, and the X-Men's Cyclops travel to the World, an artificial, time-altering environment designed by Weapon Plus to quickly develop and evolve new generations of super-soldiers.

Shocked at learning the terrible details of his past (including his role in the slaughter of the entire population of Roanoke while under the influence of Weapon X), Wolverine initiates the self-destruct sequence for the space station before catching and apparently killing Ultimaton (who reappears later as a subordinate[12]).

The pair reluctantly joins forces and travels to the site of Roanoke, a town whose inhabitants were slaughtered after Weapon X unleashed a brainwashed Wolverine on them years earlier.

Though despising him after a past encounter in Madagascar, Mystique finds Fantomex in Monte Carlo, once again operating under the pretense of being a mutant thief, and learns of Shortpack's plan.

[24] The first mission of the new team is an assassination job to kill Apocalypse, reborn in the form of a child and being indoctrinated by Clan Akkaba on their Moon base.

[27] Fantomex is later abducted by Captain Britain who brands him a dimensional threat and take him to Otherworld, where an interdimensional court sentences him to erasure from existence itself.

Together they encounter the Skinless Man and rejoin their teammates to defeat The Goat, a corrupted future incarnation of Psylocke and Captain Britain's older brother Jamie Braddock, who attempted to consume the multiverse.

He proves a questionable ally, as he constantly bickers with Psylocke and has a psychic sexual relations with Meme,[33] who he really knows is actually Hope Summers (who Cable thinks is in a coma).

[37] Instead of fighting him head-on, Hope implants a thought into his mind that one cannot be perfect, unless you have a well rounded personality, which includes inadequacies and insecurities.

[38] He subsequently assists Magneto and his team of X-Men fight Clan Akkaba, while secretly working to take down the sinister Someday Corporation.

He once kissed his X-Force colleague Doctor Nemesis in surprise on the lips in thanks for calling him "the best", showing that he is open to same-sex intimacy.

At the conclusion of the confrontation, Fantomex sacrifices his body so that Xavier can return to Earth while he remains on the astral plane in the professor's place, Fantomex reasoning that nobody knows who he is outside of the role he was cast in by the Weapon X program, whereas this sacrifice will ensure that he is remembered for a great act by allowing Charles Xavier to return to life.

[42][43] Fantomex has microtechnology laced into his blood; with nanites in his brain prohibiting him from believing in anything greater than himself, such as gods or any supernatural beings to the concept of true love.

[49] To that extent he can affect pain resistance, self-healing and enhanced physical abilities such as registering frequencies beyond the hearing range of normal humans or using sheer strength to scale an inclined surface and possessing a healing factor.

These allow his mind to remain completely unreadable, even facing the most powerful telepaths of the Marvel Universe (Professor X and the Shadow King among others).

[55] Fantomex would seek to curb his flawed state by incorporating a super soldier serum derivative which had afflicted Nathan and Hope Summers while a part of Cable's X-Force team.

Having managed to copy an alternate reality variant known as the Morituri Process reworked into product contraband called the Volga Effect; as a digitized format.

Initially believing the SS Serum burning out Hope's frail system on account of her body being unable to handle it, albeit without any harmful side-effects the chemical variant came with.

That being where the bestowed superpowers caused a fatal burnout resulting in the recipient's molecular biology catching fire and exploding.

[57] It was not until former X-Force associate Domino shot him in the head and killed him did the binary compendium of the Volga formula take effect.

[66] In the Here Comes Tomorrow storyline, set in an alternate timeline 150 years in the future, the entire world is ruled by Beast (possessed by Sublime).

is a member of this era's X-Men, which includes Wolverine, Tito (Beak's grandson), Tom Skylark and his Sentinel known as Rover, Three-in-One (the Stepford Cuckoos), No-Girl, and a reformed Cassandra Nova as their leader.

[67] Fantomex is depicted briefly in X-Men: The End as part of X-23's dream induced by the Ladies Mastermind, as she is stated to be in love with him in this reality.
