Travelling to the mystical realm of Svartalfheim to confront its king, Malekith, who had taken possession of four of the rings of the Mandarin, Iron Man first attempts to use stealth and guile. But when this fails, and he is hunted and wounded, he resorts to having this armor teleported in. It is heavy with iron armor plating, and its weapons include four large, extendable blades on its forearms and the ability to douse its surroundings with fine iron 'chaff' - iron being poisonous to elves.
