With a past shrouded in mystery, Wolverine’s memories are full of government secrets, traumatic events, and death. Remembering only escaping Weapon X and later joining Alpha Flight, the man known as Logan was approached with a chance to change the world, by Professor Charles Xavier. After joining Professor X’s X-Men, Wolverine has been using his mutant powers, to heal at an accelerated rate, enhanced physical condition, animal-like instincts, and razor sharp bone claws that protrude from between his knuckles laced with the indestructible metal Adamantium, to fight for the peaceful coexistence of mutants and humans most of his life.
Wolverine was created by Len Wein, John Romita and Herb Trimpe, first cameo appearence in Incredible Hulk #180 (Oct 1974) and first full appearence in Incredible Hulk #181 (Nov 1974). Since then, Wolverine has been one of the most well-known and popular Marvel Comics characters rivalling Spider-Man and Hulk, throughout his entire publication history and even in other media.
Wolverine also exists on Earth-616 mainstream universe as one of his other iterations: a time-displaced elder Wolverine.
