Wolverine was Never Intended to be a Mutant or an X-Men Member
It's impressive that Wolverine is one of the most well-known comic book characters in the world despite not appearing in either the MCU or the DCEU. Hugh Jackman's portrayal of Wolverine in multiple movies helped him establish himself as a popular figure and the most well-known X-Man. But for the resourceful little Canadian, it wasn't always in the cards. He wasn't even a mutant when he initially appeared in The Incredible Hulk; he was merely a minor character.
Roy Thomas, who co-created Wolverine, has admitted that all he saw in the character was a hero. Just a person with claws in the Canadian woods; neither mutants nor the X-Men. Because a wolverine is a little animal, he informed illustrator Len Wein that he was Canadian, went by the moniker Wolverine, and was only five feet tall. And from there, one of Marvel's most well-known characters' mythos was born. Marvel chose a diverse cast of mutants when they decided to revamp the X-Men in 1975 to resurrect the failing series for a global audience, and everyone's favorite Canadian made the roster.
