Adam Jensen

Adam Jensen is the mechanically augmented protagonist of Deus Ex: Human Revolution. He is voiced by Elias Toufexis.

Early life
The lead security manager for Sarif Industries, Adam Jensen is a calm, collected ex-cop with training in both close quarters combat and handling of various firearms. He is David Sarif's go-to guy for security matters and is largely relied upon to handle external threats. He was hired after he quit the Detroit S.W.A.T force, where he was once part of Team Two. His girlfriend, Megan Reed, is a scientist at Sarif and was the one who pushed David to hire him.

Born in 1993, Jensen was part of a military project testing genetic therapy treatments on infants. As part of the experiment, every other infant in the same cycle was killed, but Adam survived, and somehow his genetic makeup was altered. But his birth parents, not wanting another group of infants to undergo the same treatment Adam did, burned down the facility at White Helix laboratories. Both were killed in the fire and baby Adam nearly died as well, but was rescued by a kindhearted worker named Michelle Walthers.

Walthers gave up the baby Jensen for adoption, and he was eventually picked up by two loving parents. He then went on to lead a relatively normal life, earning an Associate's Degree of Criminal Justice from the University of Phoenix. He then joined the Detroit police force at the age of 21. Four years later he volunteered for its SWAT division, and was accepted under the command of Quincy Durant.

Jensen rose quickly through the ranks of Team Two, but his career came to an end during an incident known as the Mexicantown Massacre. The criminal was a young but dangerous augmented boy, and Jensen was given the order to fire. He refused and quit the force, and the order was passed on instead to his commander, Wayne Haas. Later that year he would become private security and go on to join Sarif Industries.

However, Megan was actually working on Jensen behind his back, as it is his genetic material that might be the Holy Grail of augmentation technology. Jensen was actually the mythical Patient X, unknown to even himself. With his genetic compatibility, human tissue would bond easier with mechanical parts, eliminating the issue of glial tissue buildup and Neuropozyne dependence. Megan was on the verge of releasing this research to the world before the attack on Sarif Industries.

Jensen does not know of his past and thinks of his adoptive parents as his true parents, but Sarif, being a cautious man, hired a private investigator named Brent Radford to dig up his past. Radford discovered both that Jensen's adoptive parents are not his biological parents, and that his true parents were killed in the White Helix fire. With these bits of information as well as Megan's research, Sarif was able to piece together Jensen's past, but chose not to tell Jensen for his sake.

2027
In 2027 he was preparing security plans for Sarif researchers during augmentation hearings in Washington D.C. He was critically injured when an augmented black ops team, the Tyrants, attacked the research labs, killing Sarif's key researchers and destroying all of the research concerning universal augmentation.

In an effort to save Adam's life, David Sarif provided several augmentations; while only Adam's chest and left arm required immediate replacement, the decision was made by Sarif (basing on Adam's employment contract) to replace all of Jensen's limbs. In the end, his augmentations included two cybernetic arms, linked by metal bars sunk under his chest, a pair of retractable head-mounted sunglasses, the Infolink and various others, some which were left inactive at the time. He was sent home to recuperate afterwards, struggling to come to terms with his body's fusion with machines. Six months later, he was pulled out of the sick leave by David Sarif to the SI manufacturing plant in Milwaukee, to secure the prototype of the Typhoon Explosive System augmentation, and release the hostages captured by a Pro-Human purist organization known as Purity First, led by Zeke Sanders.

Making his way through the factory, Adam eventually found the room where the Typhoon data was being stored. In there, he also found an augmented hacker, who appeared to be a member of Purity First, attempting to steal the data. Upon being discovered, the hacker committed suicide by shooting himself in the head, but not before urging Adam to help him. Jensen secured the Typhoon afterwards, and continued through the plant to find Sanders, upon Sarif's orders. Once he finally caught up, he negotiated the release of the plant manager, Josie Thorpe, whom Sanders took hostage. Adam was able to reason with Zeke, revealing that the hacker was augmented, and the whole plan was for Sanders and his group to die in the plant. After freeing Josie, Jensen let Sanders go, hoping that it would lead him to the mastermind behind the attacks on Sarif Industries.

Upon returning to Sarif HQ in Detroit, Jensen was tasked with retrieving the dead hacker's Neural Hub from the Detroit Police Department morgue. At the police station, Adam met up with fellow ex-member of SWAT Team Two, Wayne Haas, who was demoted to a desk sergeant after the Mexicantown Massacre, following the order that Jensen refused back then. Jensen managed to square the matter with Haas, and made his way to the morgue. Once there, Jensen learned that the hacker's Hub was modified with a wetdrive, and took it back to his apartment for Frank Pritchard to examine it remotely. Pritchard found out that the modification turned the hacker into a 'human proxy', allowing someone else to hack through them, and traced the origin to an abandoned factory complex in Highland Park. He also informed Adam that there was a transmitter in Derelict Row, a district of Detroit, which kept an open backdoor to the Sarif Industries network.

Jensen made his way there, and shut the transmitter down, after which Faridah Malik took him to the Highland Park Warehouse. Shortly after, Adam witnessed the arrival of two members of the Tyrants, Barrett and Fedorova, as well as another appearance of their leader, Jaron Namir. Barrett said the operation was compromised, and that they have failed to retrieve the Neural Hub, despite the fact the Police Station was on lockdown by the orders from Joseph Manderley. Following them into the factory, Adam discovered that it was a front for a FEMA internment camp, located on the lower levels. In one of the rooms, Jensen stumbled upon Namir and Fedorova as they were preparing to leave, but was briefly incapacitated by Barrett before he could stop them. Jaron ordered Barrett to get rid of Adam and escaped with Fedorova during the fight, which Barrett ultimately lost.

After a brief interrogation, he said that Sarif Industries wasn't targeted by FEMA, but someone else, and said to go to Heng Sha to find out who, before setting off the grenades strapped to his chest, killing himself in the process. Afterwards, Jensen made his way back to the main level, and Malik took him back to Sarif to report on the situation.

Behind the scenes

 * Like JC Denton, the protagonist of Deus Ex, Adam has sunglasses, and wears them during night time. His voice also resembles JC's, being very dry and somewhat emotionless. In addition, when he was not mechanically augmented, he looked very similar to Paul Denton, the brother of JC.
 * Adam Jensen, because his molecular structure is special, doesn't need the Neuropozyne treatments all other mechanically augmented need to prevent scarring and rejection.
 * His bloodtype is O negative.
 * He lives in a luxury apartment complex in downtown Detroit named the "Chiron Building". In Greek mythology, Chiron was considered to be the superlative centaur - intelligent, civilized, and kind. He had a unique lineage and, as a child, was taught by the sun god, Apollo.
 * There is speculation that Adam Jensen's first name references Adam, the first man created by God according to the Bible. This could fit with JC Denton's initials standing for Jesus Christ.
 * Adam Jensen's last name is an homage to the game designer Jane Jensen.
 * Elias Toufexis, the voice actor for Adam Jensen, is the husband of Michelle Boback (the voice of Megan Reed)
 * "Jensen" is a Scandinavian name.
