Iron Man is a superhero appearing in American comic books published by Marvel Comics. The character was co-created by writer and editor Stan Lee, developed by scripter Larry Lieber, and designed by artists Don Heck and Jack Kirby. The character made his first appearance in Tales of Suspense #39 (cover dated March 1963), and received his own title in Iron Man #1 (May 1968). Also in 1963, the character founded the Avengers alongside Thor, Ant-Man, Wasp and the Hulk. A wealthy American business magnate, playboy, philanthropist, inventor and ingenious scientist, Anthony Edward Stark suffers a severe chest injury during a kidnapping. When his captors attempt to force him to build a weapon of mass destruction, he instead creates a mechanized suit of armor to save his life and escape captivity. Later, Stark develops his suit, adding weapons and other technological devices he designed through his company, Stark Industries. He uses the suit and successive versions to protect the world as Iron Man. Although at first concealing his true identity, Stark eventually publicly reveals himself to be Iron Man.
Captain America is a superhero appearing in American comic books published by Marvel Comics. Created by cartoonists Joe Simon and Jack Kirby, the character first appeared in Captain America Comics #1 (cover dated March 1941) from Timely Comics, a predecessor of Marvel Comics. Captain America was designed as a patriotic supersoldier who often fought the Axis powers of World War II and was Timely Comics' most popular character during the wartime period. The popularity of superheroes waned following the war, and the Captain America comic book was discontinued in 1950, with a short-lived revival in 1953. Since Marvel Comics revived the character in 1964, Captain America has remained in publication. The character wears a costume bearing an American flag motif, and he utilizes a nearly-indestructible shield that he throws as a projectile. Captain America is the alter ego of Steve Rogers, a frail young artist enhanced to the peak of human perfection by an experimental "super-soldier serum" after joining the military to aid the United States government's efforts in World War II. Near the end of the war, he was trapped in ice and survived in suspended animation until he was revived in modern times. Although Captain America often struggles to maintain his ideals as a man out of his time, he remains a highly respected figure both with the American public and in the superhero community, which includes becoming the long-time leader of the Avengers.
Doctor Stephen Strange is a fictional character appearing in American comic books published by Marvel Comics. Created by Steve Ditko with Stan Lee, the character first appeared in Strange Tales #110 (cover-dated July 1963). Doctor Strange serves as the Sorcerer Supreme, the primary protector of Earth against magical and mystical threats. Strange was created during the Silver Age of Comic Books to bring a different kind of character and themes of mysticism to Marvel Comics. The character starts as a brilliant but egotistically arrogant neurosurgeon whose hands get injured in a car accident. Because his hands have severe nerve damage from the accident, he is told that current medical therapy and rehabilitation would not be enough to enable him to practice again as a surgeon. Unable to accept this prognosis, he starts to travel the world searching for alternative ways of healing, which leads him to the Ancient One, the Sorcerer Supreme.
The Hulk is a superhero appearing in publications by the American publisher Marvel Comics. Created by writer Stan Lee and artist Jack Kirby, the character first appeared in the debut issue of The Incredible Hulk (May 1962). In his comic book appearances, the character, who has dissociative identity disorder (DID), is primarily represented by the alter Hulk, a green-skinned, hulking and muscular humanoid possessing a limitless degree of physical strength, and the alter Dr. Robert Bruce Banner, a physically weak, socially withdrawn, and emotionally reserved physicist, both of whom typically resent each other. Following his accidental exposure to gamma rays while saving the life of Rick Jones during the detonation of an experimental bomb, Banner is physically transformed into the Hulk when subjected to emotional stress, at or against his will. This transformation often leads to destructive rampages and to conflicts that complicate Banner's civilian life. The Hulk's level of strength is normally conveyed as proportionate to his level of anger.
The Avengers are an all-star ensemble cast of established superhero characters from the Marvel Comics portfolio. Diegetically, these superheroes usually operate independently but occasionally assemble as a team to tackle especially formidable villains. This in contrast to certain other superhero teams such as the X-Men, whose characters were created specifically to be part of their team, with the team being central to their identity. The Avengers were created to create a new line of books to sell and to cross-promote Marvel Comics characters. An Iron Man fan might buy an Avengers book because Iron Man appears in them, and perhaps in turn take an interest in Thor, who appears in the same book as Iron Man's friend and comrade.[2] The cast usually features a few highly popular characters who have their own solo books, such as Iron Man, alongside a number of lesser-known characters who benefit from exposure, such as Quicksilver.
