Today, Marvel's Avengers are some of the most recognizable fictional characters in the world and a dominant pop cultural force. While they've become the center of the Marvel Universe in the past decade, the Avengers lingered in Marvel's mid-tier behind Spider-Man and the X-Men for years. Regardless of their popularity, the Avengers have consistently represented the epitome of heroism within the Marvel Universe.

When Stan Lee and Jack Kirby created the Avengers in 1963, they brought together the established heroes Thor, Hulk, Ant-Man, Wasp, Iron Man and shortly thereafter, Captain America. When that group gave way to "Cap's Kooky Quartet" in 1965, it established the team's rotating roster that would eventually include most of Marvel's heroes. With that ever-changing line-up, "Avengers" introduced new characters and spun-off into several ancillary titles that followed multiple affiliate teams over the years. Thanks to some of comics' greatest creators, the Avengers have starred in classic tales like "The Kree-Skrull War" and modern landmarks like "Civil War." After successful relaunches made them the focus of Marvel's publishing line in the mid-2000s, the Avengers became the driving force of Marvel's Cinematic Universe. Now, CBR wants you to test your Avengers IQ and see how well you know Marvel's premiere super-team.
