Wolverine

Of course, the most famous entry on this list had to be Wolverine. Wolverine is a Canadian human mutant whose real name is James “Logan” Howlett. Having first appeared in a cameo in The Incredible Hulk #180 in October of 1974, he has gone on to be a very prominent member of various X-teams and versions of the Avengers.

His mutant powers include a rapid regenerative healing factor, nigh-immortality and superhuman senses, reflexes and animal-like attributes. But he also has incredible fighting skills and, most prominently, an adamantium-plated skeletal structure and retractable claws.

He first joined the X-Men in Giant-Size X-Men #1 in 1975 and has gone on to join related teams like X-Force, Team X and X-Treme Sanctions Executive. He first joined the New Avengers in New Avengers #6 in June of 2005, but has gone on to be an active member of the main team.
