William Stryker

A shadowy figure whose name carries serious weight in Marvel's mutant mythology, this version of William Stryker made his catalog debut in the 2009 Modern Age entry Wolverine: Weapon X Files, courtesy of creator Frank Martin Jr. With only a handful of appearances spread across titles like Age of Apocalypse and X-Men: Second Coming – Revelations, he's a rare find, sharing pages with heavy hitters like Logan, Sabretooth, and Gambit. For collectors digging into the darker corners of Marvel's mutant universe, that slim but potent footprint makes him a genuinely intriguing piece of the puzzle.
