When a foreign entity like that of a [[TheSymbiote Symbiote]], [[BodySnatcher Body Snatcher]], PuppeteerParasite, or even a [[TheCracker Hacker]] (when regarding machines like robots and computers) enters/outright hijacks a body, the possessed subject becomes what is usually called: the Host.
The basic purpose of the host varies on what the point was for it to have been hijacked in the first place. Sometimes it's used as a disguise, other times it's used as a decoy and destraction, even simply being used as a weapon and piece of armor that the possessor uses to cause sheer chaos and destruction, but sometimes... a host can be used for FetishFuel.
For details on the passive/aggressive relationships a Host can have with its "Guest," view TheSymbiote. [[NamesTheSame Has absolutely zilch to do with]] TheHost.
