The Avengers (1963)

Marvel's premier superhero team title, launching alongside the Justice League's success at DC. The original roster of Iron Man, Thor, Hulk, Ant-Man, and Wasp soon welcomed Captain America back from suspended animation in issue #4, establishing him as the team's moral center. The series pioneered rotating membership with "Cap's Kooky Quartet" and introduced iconic characters like the Vision, Scarlet Witch, and Quicksilver. Notable runs include Roy Thomas's Kree-Skrull War epic, Jim Shooter's "Korvac Saga," and Roger Stern's definitive tenure featuring the brutal "Under Siege" storyline. Running 402 issues before Heroes Reborn, this series defined team dynamics in superhero comics.
