'''{{Quote|Icarus is MJ12's newest Artificial Intelligence|AI, their answer to the Daedalus problem. Although its processing power is formidable, the designers were deliberately restrained in implementing routines for traits like creativity and moral discretion. They didn't want this one to get away.
In theory, Icarus is completely in tune with MJ12 principles and objectives, and completely subservient to its leadership. Of course, like any other eager, gifted young employee, it's impossible to predict exactly how it'll shape up under the pressure of a real-world work environment. Sometimes they get funny ideas. Icarus is displaying a curiosity about human motivations that its programmers find troubling, as well as a rather finely-drawn sense of right and wrong.|description of Icarus to JC Denton|the player|Deus Ex}}'''Icarus''' is an Artificial Intelligence that appears in the first ''Deus Ex (series)|Deus Ex'' game. Designed by Bob Page, it is used to track JC Denton and to replace the insubordinate AI before it, Daedalus. Icarus is the malevolent counterpart to Daedalus, being sociopathic and negative in contrast to it. It is voiced by Peter Marquardt.'''

Icarus was a creation of Bob Page and Majestic-12. Its purpose was the same as Daedalus: to control and sift through huge amounts of digital information, allowing it to inform and advise its handlers, and to predict and control real-world events. Icarus' creation was necessary to Page as its predecessor, Daedalus, had revolted from MJ12 control, instead assisting JC Denton along with others MJ12 wanted to destroy.

Icarus is an antagonist in the game and is generally antipodal to Daedalus. Following its Majestic-12 protocols, it tracks the movements and activities of JC from the point he escapes from his imprisonment in the secret MJ12 facility on Liberty Island. Icarus first makes contact with JC in Paris; brief communications and messages involving taunts, warnings, questions, and misinformation are received through infolinks, computer terminals, and, in one instance, a telephone call.

Throughout the game, Icarus not only harasses JC, but leads him and his allies to believe it is attempting to "kill" Daedalus. Daedalus informs them that it is being attacked by Icarus, being weakened to the point that it believes it will soon be destroyed, and as such pleas for aid to fight Icarus. These attacks, unbeknownst to them, are actually attempts by Icarus to combine the two AI's into one entity. Icarus's communications continue throughout the game up to the point where JC and the X-51 scientists, in an attempt to help Daedalus fend off its rival, accidentally cause the two AIs to merge into a new program: Helios. Bob Page then informs that he knew the two AI would combine and that they had just played right into his hands by creating an AI with Icarus's loyalty to MJ12 and Daedalus's worldwide cyber integration.

==Behind the scenes==
*The name "Icarus" is one of many symbolic names taken from the Greek mythology. In the myth, Icarus and his father Daedalus were imprisoned on an island. Icarus spent his whole life there, whereas Daedalus lived most of his life in civilization. They were trapped until Daedalus had created wings of feather and wax for both to escape with. Icarus died when he disobeyed his father and flew too close to the sun, melting the wax that held his wings together and causing him to plummet into the sea and drown.
*According to Sam Carter, Icarus is of the same design of Daedalus, but with modifications to better suit MJ12's uses.
*Icarus' avatar icon is an eyeball with a protruding iris, and emanating thin spikes all around. Surrounding the eyeball is a series of curved plates that gives the impression the eye is within a sphere. The eye probably represents Icarus' ability to see everything thanks to its connection with Aquinas (ECHELON).
*''Human Revolution'' makes reference to the mythical Icarus in its second trailer; Adam Jensen dreams he has angel wings, then flies too close to the sun, which causes them to burn away, casting him to earth. Also, the main theme is called "Icarus Theme." The reference conjoins the transhumanism theme of the game's plot, where Sarif's drive to enabling augmentation is similar to Icarus' drive to reach the sun, leading to the downfall of humanity and loss of his wings.
*In the Sci-fi novelĀ ''Neruomancer'', the AI construct Wintermute is one of the AIs created by Tessier-Ashpool. Wintermute is much like Icarus in the facts that: Wintermute has an opposite, Neuromancer, that Wintermute wants to merge with it's sibling, and that Wintermute often teases and pesters the protagonist.
