YMMV: The Night's Dawn Trilogy
- Canon Sue / Jerk Sue: Joshua Calvert is arrogant, irresistible to women, a starship captain, and finally banishes the possessed. He has unfortunate elements of this trope, but thankfully the fact that there are so many characters means that this needn't get in the way. Nevertheless, some people find him irritating - even Hamilton himself calls him a "prat".
- Complete Monster: Quinn Dexter is a Satanic cult leader who considers himself something of a God and likes nothing more than to inflict as much pain and spread as much suffering as possible. Through his sect he regularly performs human sacrifices to feed off the psychic energies derived from the victims' agonies of being tortured, raped and murdered. After he is possessed by an escaped soul from the Beyond, his will proves so strong that he regains control of his body and sets out to turn as many planets as possible into unlivable Hellworlds. He drops a meteorite on the Nyvan colony to wipe out all life on it, makes it it his mission to destroy every shred of human decency, and will devour the souls of all those he considers too weak to share the new Hell with him.
- Nightmare Fuel: Possession. The Melange. The Beyond. Also, being a ghost. If you don't want to give up your mortal life, you spend an eternity in the Beyond, where 5 minutes feels like an eternity, all the other souls are screaming to get out, and when you do get out, the souls in the Beyond compel you to open up bodies for possession by souls from the Beyond.
