- Complete Monster: Besides Frank and Julia again, Dr. Philip Channard is a psychiatrist and head of the Channard Institute with an obsession with the occult, specifically Hell. Using his facility for the as front for his studies, he has his patients solve the Lament Configuration, and observes them being taken by the Cenobites. When he gets his hands on the mattress Julia Cotton died on, Channard takes his patients to be sacrificed to complete Julia's resurrection. In return, Julia takes Channard to Hell where Leviathan looks into his mind, revealing that he would dissect animals as a child. Channard is turned into an abnormally chaotic cenobite, at which point he drops his affable façade and revels in his sadistic side, proceeding to slaughter every living thing that crosses his path, including the other Cenobites when they stand against him. It's also discovered that Hell is beginning to cross over with Earth due to Channard giving his patients their own puzzle boxes.
- Ensemble Dark Horse: This is the film where Pinhead stakes his claim as the franchise's main baddie. Overshadowing the intended Big Bad of the franchise, Julia, who is never seen again after this film.
- Fridge Horror: When Cenobites die, they revert back to their human, pre-Cenobite form. When the Chatterer dies, he turns into a teenage boy. What kind of twisted desires could a boy so young possibly have to become that?
- Nightmare Retardant: The Channard Cenobite, as his presentation has more common with the oneliner-spouting boogeymen of the eighties ("The doctor is in", "I recommend amputation!" etc.) than the dark twisted S/M demons that are the Cenobites. Not to mention his phallic head.
- The events of the film seem to suggest that Channard is a true Cenobite only immediately after his Viral Transformation (when he steps out of the chamber, he's pleased about what he's become). A moment later, though, some kind of tentacle or appendage rises above him and attaches itself to his head, and from then on, whatever that limb belongs to is controlling him. In that sense, it crosses right back over into Nightmare Fuel.
- Special Effect Failure: One of the "stone" walls of the hell labyrinth wobbles when Kirsty leans on it.
- The Woobie: Tiffany, oh so very much. Thankfully, she makes it out all right.
