Maybe it's to explore a new world. Maybe it's to be better and stronger than before. Or maybe it's a mistake and it leaves the person TrappedInAnotherWorld.

Regardless of why, this trope involves a person who can be (or who is) downloaded into a [[RemoteBody remote interface]] to interact with others or another world better (or at all). This other self is otherwise an empty shell that does nothing. Sometimes when the remote version of himself is damaged or killed, [[{{Synchronization}} he is hurt/killed back at home or in 'reality']], but the idea is, while the main body 'sleeps', a different body acts and works remotely by his commands. This is used to play games, interact with computers, or interact with an alien world.

!!Examples:
* ''Film/TheMatrix'' does this with the people who plug in.
* This happens to Tsukasa in ''Anime/DotHackSign''. Most of the other characters treat their avatars as just normal gaming devices.
* The plot of ''{{Surrogates}}'' has this happen on a global scale in everyday life.
* What [[spoiler:Yuki Nagato and the remote interfaces for the Data Thought Entity and their rival the Canopy Overmind]] are in ''LightNovel/HaruhiSuzumiya''.
* The titular Avatars in that Creator/JamesCameron film [[Film/{{Avatar}} you may have seen]].
* Done via Astral Projection in ''JohnCarterOfMars'' .
* Happens a lot in Creator/PeterFHamilton's ''Literature/TheNightsDawnTrilogy''. Ione Saldana and a couple of other characters download their own personalities into bio-engineered SuperSoldiers to fight wars. Ione lives in a space station which she herself has never left, and the other characters are often [[spoiler: dead]]. Not to mention Edenists' downloading of personality into habitat 'multiplicities', preserving their memories for centuries after their bodies are dead, or the general effect of possession. Okay, fine. The entire yarn wouldn't exist without this trope.
* Tad Willaims ''Literature/{{Otherland}}'' books are set in an AI world, so most of the main characters are avatars of assorted real life people. Orlando Gardiner, in particular, has progeria, so sometimes considers his virtual life [[spoiler:more real than his home life. Eventually, his body dies, and he becomes a permenant inhabitant of the virtual world]].
* ''Id_Entity'' is the manwha version of ''.//Hack'', except it comes with a mode where you can actually play as you sleep, through some kind of poorly explained science babble about the subconscious mind.
* In Creator/DavidWeber's ''Literature/{{Safehold}}'' series, Nimue Alban's fabulously wealthy father bought her a fabulously expensive PICA—a robotic body capable of temporarily hosting a human consciousness. Nimue mostly used it for extreme sports, but it was...[[Franchise/StarTrek fully functional]]...If You Know What I Mean. Merlin explores that aspect later, If You Know Wha—you get the idea.
* This is ubiquitous in ''Franchise/GhostInTheShell''; it's either remote interface or the person's actual brain in the avatar's body.
* TabletopGames that explores the theme of Transhumanism usually has this as an option (sometimes ''the only'' option)for PlayerCharacter, for example some ''{{GURPS}}'' settings as well as ''EclipsePhase''.
* The heroes of ''Series/StargateAtlantis'' encounter a good Replicator living on Earth. Although she helps them she is too dangerous to remain free, so they place her in a realistic virtual world where she may live as she pleases.
* This is somewhat of a plot point in the film version of Film/JohnCarter: He wasn't actually teleported to Mars, just a carbon copy controlled by his consciousness.
