sent after Karai before deciding to go after the Turtles instead out of misplaced revenge. They managed to capture Donatello, Raphael, April O'Neil and Casey Jones before cornering Leonardo and Michelangelo at Coney Island, the latter serving as a distraction while coming up with their mutant names from the van they arrived in. Steranko like "Rocksteady" while Zeck was not fond of initially "Bebop", the two ultimately escaping after briefly fighting the heroes over the retro-mutagen batch Donatello had concocted. They were able to recapture Karai and deliver her to their new master. Rocksteady became the Shredder's connection to the Russian mafia, as mentioned in "Casey Jones Vs. the Underworld".

Shredder's premonition is proven correct and the two help Tiger Claw and a new trio of Shredder mutants fend off the Turtles. The two capture Leonardo and Michelangelo when they infiltrate the base once again, and prepare to dump them into Stockman's vat of mutagen. However, the two are tricked by Leonardo to create a
