Rocksteady is an antagonist of Teenage Mutant Ninja Turtles. He was originally a human Russian arms dealer with ties to Shredder and The Foot Clan named Ivan Ilyich Steranko (Russian: Иван Ильич Стеранко). He is now an anthropomorphic white rhinoceros who is one of Shredder's hench-mutants alongside his partner, Bebop. He made his debut in Enemy Of My Enemy.
Russian Rock-Head Rhino
As Ivan Steranko
Not much is known about Ivan Steranko's origin except that he was born in 1967 in Soviet Moscow, he was better at hunting than his brother Boltak, he and Shredder have been business partners in the mafia for 10 years and he's got a diamond for a right eye because Anton Zeck shot the real eye out by accident.
As shown for 1987 Shredder and Krang in his resumé in Wanted Bebop and Rocksteady, Ivan Steranko fought as a volunteer during the wars in Iraq (1986–1989), Yugoslavia (1991–1997) and the Democratic Republic of Congo (1998–2001) and then again in Iraq (2001–2003) before he joined the Foot Clan in 2013.
The Legend of the Kuro Kabuto: Steranko hired Zeck to steal the Shredder's helmet, the Kuro Kabuto. Later, he flew in on a helicopter and saved Zeck from being killed by the Foot. When he finds out that Zeck failed to capture the helmet, he vows that to "pop his head like blueberry".
Serpent Hunt: Steranko planned on hunting Karai as a means of trading her to Shredder for a way out of the Kraang-invaded city, but when the Turtles get in the way, both he and Zeck are captured by Rahzar and Fishface and tossed into a computer-based vat of Mutagen in Stockman-Fly's lab. Steranko, having been infused with white rhinoceros DNA, turns into an 8-foot-tall humanoid white rhino with a jagged horn ripping out of his droopy beak-like nose and his shoulder pads and knuckle dusters fused to his skin. He lands right next to Zeck and complaines that he doesn't feel so well.
The Pig and The Rhino: Steranko works with Bebop to get even with Shredder for mutating them, but Shredder beats them up. He then sent the duo to find Karai, but they decide to skip their search to take their revenge on the Turtles. After capturing Raphael and Casey Jones, Steranko is tipped off by Bebop (who has just captured Donatello and April O'Neil) into cornering the other two Turtles at the Coney Comet amusement park. However, Leo was able to free the captives while Michelangelo stalled the captors, giving Steranko a tough-sounding nickname off of the van that he and Bebop arrived in, "Rocksteady", which he liked. A fight breaks out and Rocksteady is struck by a roller coaster cart and flees with Bebop. Going back to their search for Karai, the duo eventually succeeded in capturing her and delivering her back to Shredder.
The Noxious Avenger: Rocksteady is seen breaking into a abandoned Kraang ware-house with Bebop to search for Chemical X (one of the many chemicals that are needed for Shredders Mind Control Serum). While taking Chemical X, Bebop also takes some mutagen that the Kraang left behind and just as the two are about to leave, Rocksteady hears a noise outside. He tells Bebop that it is just the trashman, but gets kicked in the face by Leonardo. A battle erupts between the Turtles and the duo and Rocksteady orders that they retreat. Later, after leearning about Muckman on TV, he encounters him with Bebop and forces him to help them take Chemical X, but the garbage mutant betrays them to the Turtles and destroys the chemical with a single spit.
The Deadly Venom: Rocksteady is forced to fight Karai when she is mind-controlled by the Shredder. Karai wins and beats him, even though Rocksteady says it would be a piece of cake.
Attack of the Mega Shredder!': Rocksteady and Bebop are ordered by the Shredder to protect their lair as he senses the Turtles will make another assault on it, warning them of severe punishment if they fail. As Shredder thought, the Turtles manage to make it into the catacombs before they are chased off by Rocksteady, Bebop, Tiger Claw, and the Shredder Elite. However, the Shredder is furious by the Turtles getting that far, and threatens all of them with punishment if it happens again. Later, when Leo and Mikey attempt to infiltrate Stockman's lab to retrieve one of the mind-control worms, they are caught by Bebop and Rocksteady. As they prepare to mutate the two brothers, Leo and Mikey are able to convince them to mutate them with the Shredder Elite, but by falling for the brothers' trick, Rocksteady and Bebop end up mutating the Shredder Elite into an amalgamation known as the Mega Shredder. After the Turtles, April, and Casey are able to destroy it, Rocksteady and Bebop face Shredder, who is livid over their stupid actions, and leaves Tiger Claw to give them a fitting punishment, leaving Rocksteady and Bebop to run for their lives as Tiger Claw pounces at them.
The Fourfold Trap': Rocksteady is part of an elaborate trap, led by Karai, to capture the Turtles and April. It works, and while April is kept prisoner with Karai, the Turtles are each subjected to a torture fitting each of them. Knowing that Splinter will come to rescue them, Rocksteady and Bebop attempt to ambush and defeat him before he reaches Karai's command center, but Splinter easily overpowers and defeats them and continues on his way to saving his sons and April.
Annihilation Earth: Rocksteady catches April and Splinter when they infiltrate Shredder's lair to broker a truce with him to ask for his help against the Triceratons and save the Earth from destruction by the Heart of Darkness. At first, Shredder agrees, and Rocksteady proves his strength going horn-to-horn with the Triceratons. However, putting his vengeance over anything else, Shredder murders Splinter and condemns the Earth to annihilation. Rocksteady embraces Bebop as the two of them are some of the first victims to be sucked up by the Heart of Darkness' black hole before the rest of the Earth follows.
City at War: Rocksteady reappears as a bodyguard along with Bebop in Shredder's new lair.
Broken Foot: Rocksteady, along with Bebop and Tiger Claw are protecting Shredder's chemical factory. He fights Shinigami and the witch calls him "Dinossaur" which makes him in fury run to her until he misses and knocks Bebop to the ground. He tries to hunt the Turtles down using the van with his name.Later, he fights Mikey that insults her mother and makes him destroy the Foot-Bots and stop Bebop from finish Shinigami. He tries to stop the Turtles from escape but he fails.
The Super Shredder: As Shredder is turning into a mutant due to Stockman injected him the rest of the unstable mutagen. Rocksteady appears as he heard a noise and gets scared by seeing Shredder in his new mutant form. Later he confronts The Turtles, April and Karai with Bebop and Elite Foot-Bots after Splinter and Shredder fall into a abyss.
Darkest Plight: Rocksteady lost the Turtles and later he and Bebop are ordered by Shredder to look for Splinter in the abyss to make sure he's dead. Bebop refuses to go down the abyss so they do rock, paper and scissors but then they hear Michelangelo, Donatello, Raphael and Casey Jones arriving to the under-city to also look for Master Splinter so they hide. Casey throw hockey discs that hit Bebop descamoflaging him so now they fight Raph and Casey while Donnie and Mikey search for Splintter through the abyss. He and Bebop get beaten.
Requiem: Bebop and Rocksteady lead the Turtles and Leatherhead to the Coney Island amusement park as a setup so Splinter's allies would be divided into separate teams. Later, the Turtles think they have won and beat them, but notice Bebop and Rocksteady escaping.
As Ivan Steranko: Steranko is large, muscular and wears a black suit with spiked shoulder pads, a black dress shirt, a red tie, an Ushanka with a yellow star, and a pair of knuckle dusters (with the Soviet Russian symbol on them). He has blonde hair and a diamond right eye, as well as several scars on his face.
As Rocksteady: Rocksteady has a jagged horn ripping out of his hook-lipped nose and wears a beige tank top, brown bandoliers and camouflage pants. His shoulder pads and knuckle dusters are fused to his grey skin.
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 fighting skills to suit his new form. He even likes the name Michelangelo gave him.
Born by Shredder from Russian arms industry officer Ivan Steranko, Rocksteady swears allegiance to Shredder and agrees to team up with his partner-in-crime Bebop to form the dynamic duo of Bebop and Rocksteady. Our heroes need to use extreme caution when dealing with this mutated rock-headed rhino. He is the brains and brawn of the partnership and could deliver quite the feast to Shredder when the main course is Turtle Soup!
