Wolverine was never actually called "Wolverine" in the Age of Apocalypse timeline. Instead, he retained his code name Weapon X. In this reality he never had his adamantium ripped out and it was Magneto that helped him to control his feral rages. Weapon X was a loner and initially an unwilling recruit to the X-Men. He reconsidered after meeting the team’s telepath, Jean Grey. The two had an instant connection and eventually became lovers.

Logan trained Magneto’s newer recruits, including Kitty Pryde also known as Shadowcat. Unbeknown to the rest of the X-Men, Magneto had asked Weapon X to train the girl as an assassin. Weapon X taught Shadowcat everything he knew and even crafted a pair of claws similar to his own for her with Magneto’s help.

One of the main differences between Weapon X and the Earth 616 Wolverine is that Weapon X’s left hand is missing. The hand was blasted off by the Prelate Scott Summers, a villain in this universe when Weapon X tried to rescue Jean from Mr. Sinister. He succeeded and gouged one of Summers' eyes out in return. He also has a number of facial tattoos. Not willing to return to the X-Men, Logan and Jean worked on their own.

After months of guerrilla warfare, they were contacted by Sinister who revealed Apocalypse’s plan to attack the humans in Europe. Logan and Jean delivered this information to the Human High Council and learned of the Council’s plan to launch nuclear missiles on America to stop Apocalypse. In the end, Jean was killed by the Prelate Alex Summers but Logan avenged her.

Interestingly, his relationships with many of his old enemies were changed. Sabretooth is no longer his nemesis but instead an ally, although the two still shared similar powers.
