A woman named Shu Han gets out a distress call, which eventually reaches the Avengers, saying that she is being held captive by the Yellow Claw, a biochemical genius who has greatly extended his life with his scientific methods, and is intent on destroying Western civilization. The Avengers go to investigate. They fly to the Yellow Claw's island fortress, where the Wasp and Vision are able to infiltrate while the others try to land the quinjet. The Vision is captured by the Yellow Claw. The other Avengers battle several of the Claw's monsters, and eventually get inside his fortress. The Yellow Claw tells them that he has the Vision captive and can kill him at any time. The Avengers tell him why they've come. The Claw allows Shu Han to leave with the Avengers. He also frees the Vision. After the Avengers have left, the Claw tells of his plan to create genetically superior sons with his handpicked wives, then let them all battle to the death to determine which one is the fittest to rule. Then he will eradicate the eastern world and his offspring will rule, and shall be the last children on earth.
