Only one person can really say for sure: <PERSON>'s original creator, writer <PERSON>, who wrote the character into a cameo appearance in The Incredible Hulk #180 way back in 1974, and then placing him as the Hulk's newest adversary in the follow-up book, The Incredible Hulk #181. Although designed by art director <PERSON>., <PERSON> was the one who decided how to write Wolverine. He was picked due to his work on an earlier comic called Brother Voodoo. Editor-in-chief <PERSON> was so impressed by <PERSON>'s writing of accents that he called <PERSON> up and told him "You are doing something I cannot do as a writer; I cannot write accents to save my life. I'd love to see how you'd do a Canadian accent. Uh, <PERSON>'s a great name." <PERSON> then did research on wolverines, and noted that "They are short, mean, nasty little creatures with razor-sharp claws that will attack anything twice their size and don't go anywhere near them; they will kill you. 417
Well, that's a character defined right there." <PERSON> implemented these characteristics into <PERSON>, adding an indestructible metal skeleton (later called Adamantium) and an accelerated healing factor, therefore giving him the necessary tools to battle a character like the <PERSON> in a believable sense; most of this information can be found in the DVD, X-Men Revealed. Later on, when X-Men Origins: Wolverine was released, <PERSON> said on the Blu-Ray special features that 'he has read "Ten things you didn't know about <PERSON>", which states that the character was originally intended to be a mutated wolverine. I write stories about human beings, not evolved animals (with apologies for any stories I may have written that involved the High Evolutionary). The mutated wolverine thing came about long after I was no longer involved with the book. I'm not certain if the idea was first suggested by <PERSON>, the late, much-missed <PERSON>, or <PERSON> when he came aboard as artist, but it most certainly did not start with me.' This second part of Wolverine's explained past can be found on Wikipedia. I hope this article helps. 167
