Ivan Steranko, aka Rocksteady, is an enemy of the Ninja Turtles. He was formerly a Russian arms dealer and Russian Mafia Boss with a prosthetic diamond eyeball, who was an old friend of Oroku Saki from the past. He was the boss of Anton Zeck, an African-American master thief who steals artifacts for him. One of Zeck's missions was to steal the Kuro Kabuto from Shredder, which Zeck does until Leonardo takes the helmet away from him. Due to a series of events involving him and Zeck capturing Karai to bargain with Shredder, he ends up mutating into a mutant white rhinoceros as a punishment by Shredder. Due to their mutations, the duo was forced to join The Foot Clan in order for them to live and to capture Karai once again. After Shredder was resurrected by Kavaxas and the demodragon takes over control of The Foot Clan, him and Bebop decide to leave the clan. He wields a Golden Hammer, a Sickle, and Knuckledusters as his signature weapons of choice. Ivan Steranko debuts in Enemy of my Enemy and Rocksteady debuts in Serpent Hunt.

- In his debut episode, Enemy of my Enemy, Ivan Steranko's name was never mentioned during the episode, but it was seen in the credits as "Steranko". In his later return, The Legend of the Kuro Kabuto, Steranko's full name was revealed to be "Ivan Steranko".
- Steranko has a hammer and a sickle molded on his knuckle dusters, which are the symbols of the Soviet Union.
- Although Rocksteady is a white rhinoceros (as seen in a computer screen in Stockman-Fly's laboratory as shown in a silhouette of a white rhinoceros), his nose is shaped like a black rhinoceros since the white rhinoceros does not have a beak-shaped mouth. This could either be an animation error or the DNA placed in the mutagen was a mixture of both rhinoceros species.
- Ivan Steranko shares his last name with Jim Steranko, a famous comic book artist.
