| StoryTitle1 = Vengeance Is Ours! | Synopsis1 = After jumping over the edge last issue, the Avengers have very little time to rescue Captain America, but with quick thinking they manage it. The Swordsman is outraged and attacks them. During the battle he starts to vanish mysteriously. He awakens in the lair of the Mandarin. The Mandarin allies himself with the Swordsman, giving him a more powerful sword. He then creates an image of Iron Man which he sends to the Avengers, vouching for the Swordsman's membership. Once in the Avengers HQ he plants bombs to destroy them. He later has a change of heart and tries to remove the bombs, but is caught by Captain America, who believes he is attaching them. After a brief battle the Swordsman escapes again. | Writer1_1 = Stan Lee | Penciler1_1 = Don Heck | Inker1_1 = Wallace Wood | Colourist1_1 = Stan Goldberg | Letterer1_1 = Artie Simek | Editor1_1 = Stan Lee
