Adam Jensen

"I never asked for this."

- Jensen's famous quote Adam Jensen is the main protagonist of Deus Ex: Human Revolution, its DLC, The Missing Link and it's upcoming sequel, Deus Ex: Mankind Divided. He's the Cheif of Security at Sarif Industries at first and goes on a manhunt for The Tyrants who raided the facility but after an even known as the Aug Incident, he's now a member of Task Force 29 & the Juggernaut Collective as he hunts down both augmented terrorists and the Illuminati.

He is voiced by Elias Toufexis.

Personality
The personality that Jensen exhibits during Deus Ex: Human Revolution is fixed in many ways, but the player has the ability to shape it in various others. The game provides continuous opportunities for the player to decide Jensen's ethical/moral stance towards social behavior and the use of violence. The player can also shape Jensen's evaluation of his own role in events that have already taken place by the time the story begins - such as the Mexicantown Massacre.

The most prominent fixed element of Jensen's personality is that he is a loner. He undertakes missions exclusively alone and rarely displays strong emotion even towards close acquaintances. He's also stoic and maybe even a bit melancholic when expressing himself, rarely showing any emotion, be it happiness, joy, sadness or anger when speaking to others. However, a few people in Jensen's life do provoke him to more emotional reactions and his inner thoughts and monologues are highly emotional, but he keeps those emotions to himself. He retains strong affection for his ex-girlfriend Megan Reed. He nearly commits suicide in an attempt to save his new friend and lover, Katrina Sutherland. Although he has a general distrust of authority - perhaps as a consequence of his experiences in law enforcement - Jensen respects and trusts his employer,David Sarif, and reacts badly when that trust is not reciprocated. He shows antipathy towards his colleagueFrank Pritchard, who regards him with disdain in return - although their dislike of each other appears to be fairly superficial.

When first facing Zhao Yun Ru, Jensen hesitates and is easily distracted when Zhao pretends to be a victim. It slightly suggests something about Adam's personality, possibly that he has a soft spot for ladies in distress, although the reaction could have been manipulated by a CASIE augmentation.

Many of the fixed events in the game, and especially in the comic series, describe Jensen as a professional operative with a high regard for innocent civilians in danger.

Furthermore, from various preview videos and from objects seen in game, it can be inferred that Adam is both a smoker and a drinker. Adam, before he is augmented, is able to cope with a lot of things, as he takes his separation from Megan Reed in stride. Thus, we see little evidence to provoke his indulgence in vices. However, after the attack, he loses everything that matters to him: his humanity, his lover, and his dog, among others. The result of this pushed Adam into a depression (he smashed his fist into his mirror), driving him to smoke and drink. We can draw from this that, regardless of the choices the player makes in the game to indicate otherwise, Adam Jensen is often given choices to perform actions that tend to his soul.

Human Revolution's gameplay does not usually force the player to commit to a particular personality, or at least not completely. The player has freedom to be inconsistent. It is possible for the player's actions to result in the implication that Jensen is extremely manipulative, to the point of being sociopathic. Practical consequences from the game world and story are mostly determined by what happens, rather than by an assessment of why the player did it, so Jensen's motivations are largely open to the player's interpretation.

Trivia

 * Adam is similar to Alex Murphy; both are cops (or ex-cop in Adam's case) who are killed by violent terrorists (Clarence Boddicker and the Tyrants, respectively) and saved using massive cybernetic surgery. In both cases, they swear revenge on the ones who killed them, which they both get.
