a member of the Russian mafia who willingly underwent a series of chemical and radiation treatments meant to give him an artificial skin covering that would grant superhuman strength. After successfully completing the treatment, Sytsevich rebelled against the Eastern Bloc agents who gave him these powers, destroying their laboratory. He was subsequently hired to kidnap Colonel John Jameson and obtain the extraterrestrial spores to which Jameson was exposed during a space mission, but Sytsevich was defeated by the superhero Spider-Man and taken to prison. After serving his sentence, the Rhino was approached by the same scientists for more augmentation. This time, they used the same gamma radiation that granted the Hulk his abilities to further increase the Rhino's strength. They also equipped him with a more durable, acid-proof suit that would further increase his abilities.

Samson took the Rhino to Project P.E.G.A.S.U.S., where he was part of a failed prison break involving Moonstone, Blackout, and Electro. While being transferred to another facility, the Miracle Man attempted to free the Rhino, who wanted to stay in P.E.G.A.S.U.S. for medical treatment.
