Ivan Steranko (2012 TV series)

Steranko​ is a Russian arms dealer and a supposed old friend of The Shredder's. He appeared in "Enemy of My Enemy". He was giving Shredder weapons in exchange of something unknown (presumably gold). He also has one diamond eye.

Steranko is voiced by Fred Tatasciore.

Appearance
Steranko wears a black suit with shoulder pads with spikes on it, a black undershirt, a red tie, an Ushanka with a yellow star on it, and on his fists two knuckles presumably made of gold. He is blonde-haired and has a diamond eye, as well as several scars on his face.

History
Appears to be close to Shredder, given an offhanded mention that they're "old friends". He is first seen talking to Shredder, albeit left unnamed, about a weapons deal. He is presumably knocked unconscious by the weapon that was meant to incapacitate Shredder.

Trivia

 * Steranko is left entirely unnamed in his debut episode, with the only indicator about his name being the end credits.
