MacDonald "Mac" Gargan is a supervillain appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist Steve Ditko, the character first appeared in The Amazing Spider-Man #19. Mac Gargan is a recurring antagonist of the superhero Peter Parker / Spider-Man. He debuted as a private investigator hired by J. Jonah Jameson to learn how Peter Parker took pictures of Spider-Man. In the following issue, Jameson decided to turn Gargan into a deadly adversary for Spider-Man through a barely-tested procedure, which left Gargan with an irremovable scorpion-themed armor and the predatory instincts of the arachnid. Driven insane by his mutation, Gargan instead turned to a life of crime as the Scorpion, and went on to menace both Spider-Man and Jameson, whom he held responsible for his transformation. Since then, having finally removed the armor, Gargan has also served as the third host of the Venom symbiote, and a member of the Dark Avengers as Spider-Man, but eventually returned to his Scorpion alias as it kept him alive due to the strain both the neural-armors and symbiote put on his body.
