After 74 villains break out of prison, Marvel's most powerful superheroes team up to capture all of them, and also to defend the Earth from widespread threats.

In New York City, there is a mass breakout of supervillains from various S.H.I.E.L.D prisons by a mysterious mastermind. Against this threat that no single hero could have withstood, Iron Man, Giant Man, the Wasp, Thor and the Hulk work together to defeat the menace. Inspired by this victory, Iron Man convinces the others to form a permanent team, The Avengers, for the cause of justice. Together, these superheroes face new challenges, members, friends and foes as they assemble for them as one.—Kenneth Chisholm ([email protected])
