Possession is the ability for a character to take control of another character by entering their mind/body/soul. It is different from mind control, as it is done internally instead of externally. Traditionally in folklore and fiction, demons and ghosts most often have this power.

There are 3 main types of possession:

1. Physical Possession. This requires physical matter entering the opponent's body to take control of them. Examples include the Goa'uld from Stargate, Orochimaru from Naruto, and Anthrax from Bastard!!.

2. Mental Possession. This is when a character enters the mind of another via telepathy and takes control of them. Examples are the Shadow King from Marvel Comics, users of Ancient Communication Stones from Stargate, and Ino from Naruto.

3. Soul Possession: This is a form of soul manipulation when a character takes control of an opponent's soul. Examples include Reborn Palpatine from Star Wars, Raest from Malazan Book of the Fallen, and Deadman from DC Comics.

4. There is also what could be called Technological Possession, which only applies to computers and machines. Examples include Motoko Kusanagi from Ghost in the Shell
