Subject: Unicorn

Milos Masaryk was a Soviet intelligence agent who was assigned as a security guard for Anton Vanko, a Soviet inventor who developed the Crimson Dynamo armor. Vanko managed to defect to the United States, and Milos’ superiors ordered him to retrieve the inventor, outfitting him with another of Vanko’s inventions: a helmet capable of projecting destructive blasts. As the Unicorn, Milos tracked down Anton Vankoa and confronted Iron Man, who was in fact responsible for Vanko's defection. The Unicorn forced Iron Man to return to Europe, but Iron Man escaped.

The Unicorn later became a free agent, appearing as an agent to Count Nefaria claiming the need to raise funds for subversive activities. However, when Nefaria was defeated by the X-Men, the Unicorn escaped.
