Wolverine's Greatest Sacrifice Stopped More Versions of Him Being Made
To stop Weapon X from creating more deadly soldiers, Wolverine sacrificed everything to stop them, resulting in the hero's death. In the Death of Wolverine storyline from Marvel Comics, Wolverine dies after shutting down the Weapon X program, resulting in the X-Men enforcer's entire body being coated in adamantium. The same metal inside his body ended up killing Wolverine, as he sacrificed himself in one of Marvel's most heartbreaking deaths.
