With super-sized conflict within the team and colossal menaces without, Stan Lee and Don Heck made AVENGERS a nail-biting, edge-of-your-seat extravaganza! The classic stories collected in this volume include battles against Kang the Conqueror, Doctor Doom, Power Man, the Enchantress and the Atlantean warlord Attuma! And while the action will keep your pulse up, twists like the departure of Captain America will deliver drama at its deepest level. Plus: Thrill to the return of Giant-Man and the Wasp - and Hank Pym's transformation into Goliath! With first appearances of the Collector, the Swordsman and the Sons of the Serpent - not to mention the Black Widow's entrance into the Avengers' world - there's no questioning that this volume is a Marvel Masterworks!
