Deus Ex Wiki

Yelena Fedorova (Russian: Елена Фёдорова) is an antagonist in the book Deus Ex: Icarus Effect and the game Deus Ex: Human Revolution. She is a senior member of the Tyrants.


Yelena Fedorova grew up among a community of ethnic Russians in Georgia during a time of tension between local Georgian and Russian militia. As a teenager, Federova witnessed the death of her family at the hands of militiamen. Since the death of her family, Federova has not uttered a word.[2] According to Eliza Cassan, Fedorova suffers from consequential mental health issues as a result of witnessing the murder of her entire family as a child.

Federova eventually became a member of the Tyrants, a mercenary group working for the Illuminati.

A woman of African descent with a cut of shoulder-length, spiky black hair, she is rarely seen out of her combat gear. Her only affectation is a silver cross on a black steel chain around her neck, a family heirloom of great personal value.[1] She has mechanical augmentations; her legs have been extended with unguligrade prosthetics that enable her to move quietly and quickly. These augmentations also gave her at least a foot height boost, giving her an intimidating figure.

Yelena is a ruthless and resourceful combatant. When she moves, she does so with unexpected agility, speed, and grace - a cobra uncoiling rapidly as it strikes. Nonetheless, because of her past, she is especially careful about avoiding civilian casualties.[1] Yelena has become adept at vigilance and is cautious of everything around her; she's not easy to sneak up on, and usually has a plan for every eventuality. Yelena had a one-night stand with Ben Saxon - possibly revealing that she has some need for human comfort.

Sometime before 2027, she is sent to kill Secret Service agent Anna Kelso, who knows too much about her superior's mysterious work and is considering joining the Juggernaut Collective. Later, in 2027, Fedorova is deployed to attack the research labs in the Sarif Industries Headquarters, where she kills many security guards and scientists. During the attack, she displays hit-and-run tactics. In one instance, she blitzed several guards with dual Hurricane SMGs before cloaking and retreating to a better position afterwards. Later, she is involved in a confrontation between Anna, Ben Saxon, and the two other Tyrant operatives. She is shot with an adhesive non-lethal shotgun round, but she is otherwise unharmed.

Later, she and Lawrence Barrett return from a failed mission to retrieve a Neural Hub from a dead augmented Purity First member, meeting up with Jaron Namir in a Highland Park factory complex. Just as they are about to leave, Adam Jensen makes his way to the lower levels, where he fights and kills Barrett. When Jensen travels to Montreal to confront Eliza Cassan, Fedorova is waiting for him in the facility that houses Eliza's AI. There, she ambushes him, but is defeated and seriously wounded, eventually succumbing to her wounds.


Fedorova is known for her trademark leg augmentations, which not only make her taller than the average human being, but also significantly faster. Fedorova also has a cloaking module, which she uses frequently throughout her fight with Jensen. She also has an augmentation known as the Claymore, a variant of the Typhoon Explosive System.


See Fedorova Tactics for tactical suggestions on how to defeat Fedorova.


  • Fedorova is a popular Russian surname meaning, literally, "of the line of Fedor". Fedor is a Russian equivalent of the male name Theodore (Greek for "gift of God"). Her surname might be a reference towards Nikolai Fyodorovich Fyodorov, a nineteenth century Orthodox philosopher who advocated life extension, physical immortality, and resurrection of the dead through scientific means. Yelena is a common female name, English equivalent of which is Helen.
    • In Deus Ex: Icarus Effect, her last name is written as "Federova", with an 'e', while in the game it's "Fedorova", with an 'o'. This minor discrepancy has not been explained as of yet. The proper transliteration of the Russian surname is "Fyodorova".
  • Fedorova never speaks in the games and novels, even when a voice actor is credited as portraying her. On page 270 of Deus Ex: Icarus Effect, a passage - "sometimes it seemed as if Jaron Namir had never known Fedorova to speak at all" suggests that she has spoken at some point in the past.
  • It appears that originally Fedorova was supposed to fight Jensen during the second visit to Detroit, in front of all the rioters, killing some with the aid of an 80-X Boxguard.
