Mikhail Kontarsky (Cyrillic: Михаил Контарский) is a character in the book Deus Ex: Icarus Effect and the game Deus Ex: The Fall. He is the Administrator of the Russian Committee on Human Augmentation, and a member of the Juggernaut Collective.
Janus, a mysterious ally of Kontarsky asks him to upload information related to the Killing Floor and the Tyrants. Mikhail is in the process of completing this request when he is interrupted by Ben Saxon. Saxon has come to assassinate him on the orders of Jaron Namir.
The Tyrants tell Saxon that Kontarsky is the one responsible for the failure of Operation Rainbird and the subsequent death of all Strike Team Six members, bar Saxon. Saxon, fueled by a desire for revenge, agrees to kill Mikhail. When Saxon confronts Kontarsky, he insists that he is innocent; a claim backed up by Janus who attempts to persuade Saxon to rethink his affiliation to the Tyrants.
- Ben Saxon can choose to kill Kontarsky or to spare him. However, even if he is spared by Saxon, Scott Hardesty of the Tyrants will shoot him via sniper rifle.
