[2] Online humorist Gail Simone was chosen to write Deadpool's final arc and the new series, with art by the UDON studio, which had recently revamped the Taskmaster in a well-received miniseries.

Simone publicly clashed with Marvel's editorial staff as the relaunched title struggled to find a foothold,[3] then left the book after issue 7.

Towards the end, two of these fill-ins were published to small fanfare: those by noted author Evan Dorkin and the acclaimed art team of Juan Bobillo and Marcelo Sosa.

However, shortly after this announcement, Marvel decided to launch a Cable & Deadpool book as a change in direction, which ended up being a much more successful consolidation of the two characters into one title.

This allowed Simone and UDON to complete their initial vision as part of a three-issue arc tying up the loose ends and restoring Deadpool for use in the new book, which was published after a month's hiatus as Agent X #13-15.

He subconsciously took the name as a combination of composers he liked: Alexander Grieg and Josef Haydn, which Sandi worked out through his fondness for classical music.

He then contacted Higashi, the new leader of part of the Four Winds organization and informed them that Alex was Deadpool, who still held the credit for killing the previous four crime heads.

Higashi was also convinced by Sandi that Alex was not Wade Wilson and was now more fully in control of his group, so he agreed to prevent any further reprisals on the foursome.

Alex was enthused at what appeared to be a fresh start for the Agency but was hurt when Outlaw announced her desire to return home to the South to care for her dying father instead, while Taskmaster declined a full-time position.

Black Swan psionically acquired Deadpool's healing factor but accidentally made contact with Nijo and personal traits had been mixed around.

Swan had also given Nijo's corpse Deadpool's regenerative powers (restoring him to a form of life 5 minutes after his death), as well as part of his personality, while Nijo also gained Swan's firearms talents, ambition, some of his refined tastes, preferences and biases, and also the bodily scarring and outrage he'd received from Deadpool throwing him face first into a white hot fireplace griddle at his home.

Alex had been affected by the device he was supposed to steal, giving him arthritis and "the American gene" (which resulted in making him incredibly fat).

He then asked Deadpool to run Agency X whilst he got himself back in shape, reasoning with himself that his only other alternatives were to shoot himself or eat Sandi and his business.

Agent X possesses a superhuman healing factor, allowing him to regenerate damaged or destroyed bodily tissue with far greater speed and efficiency than an ordinary human.

The healing factor causes his brain cells to be in a constant state of flux and regeneration, rendering him immune to psychics such as Professor X and Emma Frost.

Because of his healing factor, Agent X can push his muscles to levels beyond the natural limits of an ordinary human being without sustaining injury, giving him superhuman strength.

His musculature generates considerably less fatigue toxins than the muscles of an ordinary human being, granting him superhuman levels of stamina in all physical activities.

His agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete, on par with Deadpool.
