Iron Man Vol 1 #111

Iron Man and Jack of Hearts observe the battle between Rigellians and Wundagonans; Observer YJ-18 steps between Jack and an energy blast, possibly saving Jack's life. Another blast hits the Rigellian ship's fuel storage, causing an explosion that hurtles Iron Man into space. The Knights, suspecting he is a Rigellian robot, attack. Rigellian weapon-fire kills two Knights. Iron Man decides to side with the Wundagorians but is targeted by both sides and struck down to the planet. While Stark International and the Russian heroes continue to await new developments, a giant Swamp Insect attacks Iron Man; he defeats it but severely drains his armor leaving him unable to resist when the Knights capture him. Iron Man offers his support even as Fleet Commander Arcturus attempts to extort Jack of Hearts' support, threatening to conquer Earth if the Knights are not defeated.
