Captain America is a superhero created by Joe Simon and Jack Kirby who appears in American comic books published by Marvel Comics. The character first appeared in Captain America Comics #1, published on December 20, 1940 by Timely Comics, a corporate predecessor to Marvel. Captain America's civilian identity is Steve Rogers, a frail man enhanced to the peak of human physical perfection by an experimental "super-soldier serum" after joining the United States Army to aid the country's efforts in World War II. Equipped with an American flag-inspired costume and a virtually indestructible shield, Captain America and his sidekick Bucky Barnes clashed frequently with the villainous Red Skull and other members of the Axis powers. In the final days of the war, an accident left Captain America frozen in a state of suspended animation until he was revived in modern times. He resumes his exploits as a costumed hero and becomes leader of the superhero team the Avengers, but frequently struggles as a "man out of time" to adjust to the new era.
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 unremovable 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.
