STRANGE TALES - #160 (1967 - FN-/FN)

Confronted by his arch-nemesis, Baron Mordo, leader of the Circle Sinister, Doctor Strange tries to appeal for Mordo's aid in saving the Earth. Mordo refuses to believe Strange at first, setting his minions upon Strange and fighting him one-on-one. However, Strange is able to fight off all attackers and convince Mordo to help collect all the evil mystical essence via a rite of Exorcism. In order to collect all the fragments together, they must be contained in a human host, a role which Mordo agrees to take. After the exorcism is complete and all the evil power unleashed by Zom is collected into Mordo's body, Mordo turns on Strange, striking him down.
