This Article is about Human Possessions. Other forms of Possession are covered here.
Possessed Humans (also known as Psychokinetic Biological Inhabitation) are from Ghostbusters: The Video Game (Realistic Versions), Ghostbusters: The Video Game (Stylized Versions), Ghostbusters: The Video Game (Stylized Portable Versions), and Ghostbusters: Sanctum of Slime.
This can be found Museum of (Super)Natural History Level (realistic version). They are victims of a Possessor Ghost who are playing host to a possession. For strategy on defeating them, go to Museum of (Super)Natural History Level (realistic version) article. Among the humans possessed by these ghosts are the Ghostbusters (mostly Ray) and Walter Peck.
Realistic Version Information
According to Tobin's Spirit Guide
- Category: Class III Possessor Host
- Type: Possessor (slime neutralize)
- Attacks: Melee, Range, Rush
- Weaknesses: Slime
Possessed Humans are innocent bystanders possessed and controlled by Class III Possessor Ghosts. Slime Blower will drive Possessor Ghosts out of their human victims but beware, its lingering PK resonance is not enough to prevent Possessors from repossessing anyone already slimed.
Possessed Humans don't pose much, if any, real threat. Use your Slime Blower to drive the Possessor Ghost out of its human host, then get to work on the Possessor Ghost.
Stylized Version Information
According to Tobin's Spirit Guide
- Category: None
- Abilities: None
Certain ghosts have the ability to control living beings. To carry out this vile act, the spectre in question literally flies into its victim. At this point, a sort of ectoplasmic metastasis occurs, allowing the ghost to spread its presence throughout the body and exert its will over the muscles of the host. The degree of articulation with which the ghost can puppet its victim is dependent on the intellectual resonance of the spectre. A "smarter" and more coherent ghost will be able to mimic human (or animal) behavior more accurately, while a less advanced spectre will only be able to render the host immobile.
This is truly one of the more frightening abilities that ghosts possess. Not only is there the implication of losing control of your own body, but with the more advanced specters, you cannot be sure who is your ally and who might be host to a malevolent being.
Most ghosts aren't strong enough to pull off this trick, but when it happens, human possession is always nasty. Trust me, I know! Slime from the Slime Blower, applied directly to the unfortunate victim, is the only reliable way to force the ghost out.
Stylized Portable Version Information
Ghostbusters: Sanctum of Slime
The Possessed Humans vary in energy auras. The doctors exhibit red auras and can be exorcised with the Proton Beam while the patients have yellow auras and taken out with the Fermion Shock. The patients tend to be more dangerous and attack with flying cartwheels.
Secondary Canon History
Chi-You blasted several wedding guests and Casey Jones with energy and learned he had remotely possessed them. He had control of their bodies and minds.  Through Casey's mind, Chi-You instantaneously learned to speak in modern English and learned who the Turtles were. In turn, he manipulated the possessed humans and made them take martial arts stances but they were interrupted by the arrival of the Ghostbusters. The possessed humans soon displayed remarkable acrobatic feats under Chi-You's control. They dodged the Ghostbusters' attacks and escaped the church. On a rooftop, Chi-You recognized them as peasants unworthy of serving in his army. He released his hold on all of them, except Casey. Coming to, they saw Chi-You and ran to the roof access. In search of real warriors, Chi-You took control of NHL players at the Madison Square Garden. He further shared his power and transmogrified them into his thralls. Chi-You modified his control over Casey by the act of swallowing him, in reality enveloping him inside an adaptable ectoplasmic casing that allowed for finely tuned manipulation of the corporeal form.
