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.
As Ivan Steranko
Ivan Steranko was born to an unknown Russian couple and was raised in Russia alongside with his brother, Boltak Steranko. Ivan later on moved to New York City, where he started to work as a Russian arms dealer and apparently met Oroku Saki during his business. He also hired Anton Zeck as his own henchmen to steal artifacts for him, such as the Spear of Destiny and Excalibur. At some point, Steranko got one of his eyeballs shot by Zeck. Due to this incident, he had to get himself a prosthetic diamond eyeball. Even though Anton Zeck claims that it was an accident, it seems that Ivan Steranko does not forgive him for it.
During the events of the Kraang Invasion, Anton Zeck and Ivan Steranko were struggling to survive during the chaos taking place due to The Kraang. Since they barely had any food supply and they didn't want to rest becoming mutated, they decide to hunt down Karai to make a trade with Shredder for permission to leave New York City. After series of events that took place during the hunt for Karai Serpent, the two proceed to do the trading at the Docks. But once the Ninja Turtles came and interfered with this trading, a fight takes place between the Turtles, Anton Zeck, Ivan Steranko, and The Foot Clan. The fight comes to a conclusion once Karai has been set free, forcing the Turtles to retreat. Since Shredder was angered by what occurred, he decides to take both Zeck and Steranko captive in order for them to get their punishment. Once the two were taken to the laboratory of Baxter Stockman, Shredder proceeds his punishment by mutating them both. After Zeck was mutated by The Shredder into a mutant warthog with his technological suit merged to his body, Ivan Steranko was next to be mutated into a mutant white rhinoceros. Steranko, who didn't want to become a mutant, attempts to reason with Saki with the fact that he would be much more useful as a normal human. The Shredder made it seem like he agreed with him, but either way Rahzar pushes him into the mutagen. This causes Steranko to mutate into a mutant rhinoceros. Angered by their mutations, they attempt to fight off The Shredder with their new mutated forms, which they miserably fail to do and are forced to join The Foot Clan in order for them to be kept alive. As their first mission, they must hunt down Karai once again and they must turn her in, or they will be punished further more. When the mutant duo were in Coney Island, Michelangelo gave them both the mutant names of Bebop (Anton Zeck) and Rocksteady (Ivan Steranko), due to the van they were driving.

- 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.
