Weapon X first appeared in Marvel Comics Presents #72, cover-dated March 1991, in Barry Windsor-Smith's serialized story (running through #84). It is a program rather than a team: the covert operation that captured Logan and bonded adamantium to his skeleton, the long-hidden origin of Wolverine's claws. The "Weapon X" name has since been reused for the broader weaponization effort connected to Sabretooth, Deadpool, and X-23, and folded into the larger Weapon Plus program.

What is Weapon X

Weapon X is not a team. It is the program that made Wolverine: a covert operation that captured Logan, stripped his memories, and bonded the unbreakable metal adamantium to his skeleton and claws. It first appeared in Marvel Comics Presents #72, cover-dated March 1991, in a serialized story by Barry Windsor-Smith.

The Windsor-Smith serial (1991)

Windsor-Smith wrote and drew “Weapon X” across Marvel Comics Presents #72 to #84, and it is the rare origin that improved a character by withholding answers. It showed the procedure, the cold lab, the testing, the escape, without explaining who ran it or why, which made Wolverine’s past more unsettling rather than less. For years it was the definitive account of where the claws came from.

The name spreads

“Weapon X” outgrew the one story. Writers attached it to a broader weaponization effort tied to Sabretooth, Deadpool, and later X-23 (literally the program’s 23rd attempt, cloned from Logan). It was eventually folded into the larger Weapon Plus program, which retroactively made the Super-Soldier project that created Captain America “Weapon I.” The name became Marvel’s shorthand for turning people into weapons.

Notable issues

For collectors

The key is Marvel Comics Presents #72 (1991), the first chapter of the Weapon X story and the issue collectors anchor the program to. As an anthology issue from the early 1990s it had a large print run, so its value is tied to the Wolverine connection rather than scarcity.
