At some point in his acquaintance with Ivan Steranko, Zeck shot the Russian crime boss in the eye - supposedly by accident - resulting in Steranko adopting his trademark diamond eye.
Steranko later offered Zeck a chance to make up for his error in the past by stealing the Kuro Kabuto, helmet of the Shredder, so that Steranko could add it to his collection of artifacts. Zeck successfully broke into the Shredder's lair and stole the helmet despite running afoul of Rahzar and several Foot-Bots, but while invisible was hit by the Shellraiser. The Turtles got Zeck's bag and the helmet, but Zeck managed to plant a tracker on the Shellraiser and later knocked it over with a bomb. Zeck avoided getting involved in the fight between the Turtles and Shredder's mutants, but in attempting to retrieve the helmet from Leonardo, was soundly defeated. Leo returned his bag, but damage from the night's adventures left Zeck unable to cloak himself. He was rescued by Steranko, but then discovered that Leo had taken from the helmet from his bag and replaced it with dirty diapers taken from a city dumpster. Steranko vowed to hurt Zeck for this.
After the Kraang took over the city Steranko and Zeck have been stuck in Steranko's hideout for months with nothing left to eat but cockroaches and ketchup. They came up with a plan to get out of the city, they would find Shredder's daughter and trade her with him for a safe way out of the city, as the last thing they wanted was to be mutated by the Kraang like the other humans in the city. But the plan didn't work as intended, the turtles released Karai, and Steranko and Zeck were punished, by being turned into two hideous mutants. Anton Zeck was mutated first for his attempted theft of the Kuro Kabuto and is pushed into the mutagen vat by Fishface. After Steranko was mutated, Zeck told him that the Foot Clan turned them into "freaks" as they both bellow in pain, anger, and confusion.
