Ivan Steranko (2012 TV series)

Ivan Steranko​ is a Russian arms dealer, antique collector and a supposed old friend of The Shredder's with a diamond right eye. He first appeared in the 2012 TV series episode "Enemy of My Enemy".

Appearance
Steranko wears a black suit with shoulder pads with spikes on it, a black dress shirt, a red tie, an Ushanka with a yellow star on it, and on his fists two golden knuckle dusters, with a hammer on one and a sickle on the other. He is blonde-haired and has a diamond eye, as well as several scars on his face.

History
The story of Steranko, and under what circumstances came he in contact with the Shredder as a business partner, is largely unknown.

Enemy of My Enemy - He first 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. Shredder does have the cargo searched just in case Steranko pulled any tricks. During the Turtles' fight with Shredder, he is presumably knocked unconscious by the weapon that was meant to incapacitate Shredder.

The Legend of the Kuro Kabuto - Steranko, an ancient artifacts collector, is shown to have Excalibur and the Spear of Destiny in his collections where he has the ability to tell the difference between a fake artifact and a real artifact. He was revealed to have some past with master thief Anton Zeck, who at that time he was helping him with a vaguely defined job (allegedly, accidentally), is the one who shot out Steranko's right eye. Steranko hires Zeck to steal Shredder's helmet the Kuro Kabuto from Shredder to add to his collection. When Zeck meets up with Steranko in his helicopter, they discover that Leo had swapped it out with dirty diapers. Upon discovering this, Steranko vows to hurt Zeck for it.

A Chinatown Ghost Story - Fong said Steranko would pay through the roof for the Mystic Dagger.

Known Items in His Collection
Steranko is known as a passionate collector of legendary historical weapons. Particular highlights of his collection include:
 * Spear of Destiny
 * Excalibur
 * Armor of Alexander the Great

He has been trying to steadily expand his collection - even if the affected object is cursed or in the possessions of his "business partner".
 * Kuro Kabuto - Steranko hired Zeck to steal Shredder's helmet.
 * Mystic Dagger - The Purple Dragons wanted to sell him the dagger.

Personality
Steranko is a large, muscular man with a thick Russian accent. He describes himself and the Shredder as "old friends". His most distinguishing feature is that he seems to be missing his right eye, having replaced it with a diamond studded prosthetic.

Trivia

 * Steranko is left entirely unnamed in his debut episode, with the only indicator about his name being the end credits. Steranko's name was only mentioned in his second appearance.
 * Steranko seems to have an eye for confections, as he is able to tell that the fake Spear of Destiny is made of marzipan just by breaking it.
 * Steranko appears to be of Russian ethnicity from the former Soviet Union, but it is never specified whether he came from Soviet Russia (now the Russian Federation) or one of the other Soviet republics who as independent countries still have significant Russian populations.
