Milos Masaryk was a Russian scientist who decided to join Boris Bullski and Valentin Shatalov in their quest to orchestrate the rebirth of the Soviet Union. He then became one of A.I.M.'s top-secret intelligence agents who was selected as a test subject for combining the Extremis serum with a specialized designed iron exoskeleton armor. The experiment gave Milos the ability to fire solid energy beams of Extremis fire from his forehead and gain superhuman speed, thereby granting him the moniker of the Unicorn.
Unicorn's suit gives him the following abilities:
- Superhuman Strength: The Unicorn is superhumanly strong and can lift about 15 tons at his peak.
- Superhuman Durability: The suit gives him superhuman durability
- Power Beam: Unicorn's main weapon is a beam on the top of his helmet.
