strength and healing factor. He meets Zander Rice, killing the mutant virus' creator. Despite Rice and Pierce being killed, Logan is no match for his clone, who impales Logan through a tree with his healing factor now gone. Laura shoots the clone in the head with an adamantium bullet that Logan had kept with him for years. Logan tells Laura not to become the weapon that she was made to be, and after she tearfully acknowledges him as her father, he dies peacefully in her arms. Laura and the children bury him before continuing the journey across the border. Laura places the cross on his grave on its side to create an "X" to honor him as the last of the X-Men. Background and creation Initial character creation In the 1970s, Marvel editor-in-chief Roy Thomas asked writer Len Wein to devise a character specifically named Wolverine, who is Canadian and of small stature and with a wolverine's fierce temper. John Romita Sr. designed the first Wolverine costume, and believes he introduced the retractable claws, saying, "When I make a design, I want it to be practical and functional. I thought, 'If a man has claws like that, how does he scratch his nose or tie his shoelaces?'" Wolverine first appeared in the final "teaser" panel of The Incredible Hulk #180 (cover-dated Oct. 1974) written by Wein and penciled by Herb Trimpe. The character then appeared in a number of advertisements in various Marvel Comics publications before making his first major appearance in The Incredible Hulk #181 (Nov. 1974) again by the Wein–Trimpe team. In 2009, Trimpe said he "distinctly remembers" Romita's sketch and that, "The way I see it, [Romita and Wein] sewed the monster together and I shocked it to life!... It was just one of those secondary or tertiary characters, actually, that we were using in that particular book with no particular notion of it going anywhere. We did characters in The [Incredible] Hulk all the time that were in [particular] issues and that was the end of them." In 1975's Giant-Size X-Men #1, written by Wein and penciled by Dave Cockrum, Wolverine is recruited for a new squad. Gil Kane illustrated the cover artwork but incorrectly drew Wolverine's mask with larger headpieces. Dave Cockrum liked Kane's accidental alteration (he thought the original was too similar to Batman's mask) and incorporated it into his own artwork for the
