Wetware Body

A Wetware Body is when a biological Host is possessed by a computer or other artificial intelligence (named after a casual term for the biological equivalent of hardware, as in "Wetware CPU"). This can lead to the host acting either like a machine (monotonic, unemotional, unfocused on anything but objective) or as it normally would (if the possessing A.I. is a good actor).

Frequently this process has the side effect of causing the A.I. to feel emotions for the first time, which may act as the trigger to self-awareness and empathy, or like a virus that inevitably destroys the mechanical hijacker.

Wetware Body characters are most likely to appear in Sci-Fi horror genres, or in stories where machines and artificial intelligences are common, or at least present by some capacity.

Note: Becoming a Wetware Body means you are the host, not the possessor. For the other way around, see Wetware CPU. Do not confuse with Wet Sari Scene.

Anime & Manga

 * Ghost in the Shell has what amounts to technological zombies; human corpses with the frontal lobe replaced by a transmitter so their body can be manipulated by an A.I.
 * This is more often done by a remote control hacker, however. In the manga Human-Error Processor it's suggested locking a person suspected of being a remote-controlled zombie into a room that's a complete Faraday's cage, making it impossible for the signal to reach him, while in the 2nd Gig series it's revealed that a zombie was controlled through a wired transmitter in the same room, since the encounter was deep underground where conventional wireless signals can't reach.

Fanfiction

 * Evy is the unfortunate Wetware Body for Sideswipe in the fanfiction Transformers: Juxtaposition. Does not quite fit the trope in that Sideswipe is not an unfeeling AI (quite the opposite) but there are no other tropes that fit this peculiar time-share relationship.

Films -- Live Action

 * Ilia in Star Trek the Motion Picture gets possessed by V'Ger, a sentient being that evolved from a space probe's computer.
 * Uh, no. She gets removed from the ship entirely, and is replaced with a probe designed to mechanically replicate every organic and biochemical function V'Ger could identify.
 * In The Matrix Reloaded, Smith escapes into the real world through Bane's body.

Literature

 * Hyperion has a peculiar spin on this: Human bodies (with no memories) are grown so that an AI can take over; the AI-in-a-human-body is termed a "cybrid." The interesting thing about them is that they tend to act as human, rather than like machines (because the A Is in the Hyperion universe are remarkably human), and many if not most are based on historical personalities (one based on John Keats is central to the story).
 * A major subplot of Xenocide involves finding a Wetware Body for Jane.
 * In the Star Trek novel Q Squared one of the alternate timelines has Data as a positronic brain in a biological body. He and his android counterparts discuss the advantages and drawbacks.
 * Robert A. Heinlein's novel Time Enough for Love has one of these created.
 * The City of Illusions features a society which considers that a proper use for mentally inferior people.

Live Action TV

 * In the Stargate SG-1 episode "Entity", an alien computer intelligence that had previously taken over the base's computer system jumps to and takes over Samantha Carter's body in order to communicate its intentions.
 * In the Season 7 episode of Star Trek Voyager entitled "Body & Soul", the Doctor has to hide from a race who doesn't allow photonics. He downloads his program into Seven of Nine's consciousness and takes temporary control of her body, using it to indulge himself in way he wouldn't normally be able to do. Primarily by overeating and getting intoxicated. Hilarity Ensues.

Tabletop Games

 * Bioshells from the GURPS setting Transhuman Space are bioroids (or more rarely, reconstructed corpses) whose brains have been replaced with hardware so they can be used as a shell for an AI or Ghost.
 * In Eclipse Phase AGIs can be sleeved in biomorphs just as easily as the average human can be sleeved in a synthmorph. They can also inhabit someone's mesh inserts or a "ghostrider" implant, and control them with a "puppet sock".

Video Games

 * The Murakumo units in the Blaz Blue series are a set of Power Armors that prefer to body-jack artificially-created young women to act as hosts for their Omnicidal programming.
 * in Chrono Cross turns out to be the host of

Web Original

 * AI in Red vs. Blue--or at least certain ones--are capable of taking over the mind and body of the soldier whose armor they're in. In fairness, although the Freelancer Project didn't stop using A Is after discovering this, they did try to remove the one who started it. Emphasis on the word try, as O'Malley had figured out how to Body Surf at this point. The other two who are capable of this are . On the other hand, even if an AI is not taking over their partner's body, they still can affect their mind and thought process to some degree, as seen by the examples of.

Western Animation

 * Code Lyoko stars an antagonist A.I. named XANA, who later into the series gains the ability to possess living creatures, its logo usually illuminates and appears in a person's eyes or forehead to reveal this.
 * Courage the Cowardly Dog focuses an entire episode on the house computer possessing the bodies of the old couple that the protagonist lives with, only to grow bored and return to being the computer after much hijinks ensues to prevent the Wetware bodies from being harmed/completely DESTROYED beyond medical help.
 * Muriel only though. Eustache spends most of the episode as a talking head, after the computer accidentally breaks him.
