==Appearance==
Ivan Steranko is a large, muscular, blond-haired yet balding Russian man with a thick accent, gold tooth, and several scars on his face. Steranko wears a black suit with shoulder pads that each have two gold spikes on it, a black dress shirt, a red tie, an Ushanka with a yellow star on it, and on his fists two golden knuckle dusters, with a hammer on one and a sickle on the other. His most distinguishing feature is that he seems to be missing his right eye, having replaced it with a diamond studded prosthetic.
As Rocksteady, Steranko is a large humanoid mutant white rhinoceros with his shoulder pads (which assumed a different shape and sprouted a third spike) and the tops of his knuckle dusters melted onto his body. After this mutation, Rocksteady wears a tank top, brown bandoliers, and camouflage pants which somehow appeared on him after his mutation.
== Personality ==
Rude and humorless, Ivan Steranko is shown to not care about others, but about rare and personal items, as he is willing to be reasonable in dealing when the opportunities present themselves.
As Rocksteady, he is even more aggressive and develops more brave skills to suit his new form.
