As Don Blake operates on Captain America, the Assassin and his men drug and gas Hawkeye and Iron Man. The Assassin’s agents subdue a Thor life model decoy, believing it to be the real thunder god. Their boss immobilizes Vision with a device designed to increase the solar energy in the android’s body to an explosive level. The heroes recover and stop the Assassin from murdering Blake, whose secret identity the killer knows. In the ensuing battle, Iron Man shreds the Assassin’s costume and reveals the mercenary to be a woman. The Assassin flees to order more agents to kill other Avengers who have gathered at Avengers Mansion, but the agents don’t recognize her and shoot her dead. The Avengers defeat all the Assassin’s men. The Assassin’s brother confronts her employer, their own father, about her death, and the father kills both his son and himself.
