Fornicus is depicted as a cenobite in leather clothing, similar to a Bondage outfit and has circular saw blades embedded in his head. Like other cenobites, he possesses telekinetic powers and has the ability to summon lengths of chain to ensnare and rend his victims into pieces.
In the basement, Curt nearly summons Fornicus by tampering with his spherical puzzle orb, similar to the Hellraiser Lemarchand's box. Later, in the glass cubes, Dana sees Fornicus holding the same orb. It was at this point that she realizes that there was an element of choice in which monster would be summoned.
Fornicus, as shown behind the scenes and briefly in the film, is accompanied by two figures dressed in similar clothing, hinting that they are either his minions or partners. One is bald and has his face partly obscured by clothing. The other is a female with sinister eyes, and her mouth is similarly covered.
Fornicus was among the monsters portrayed in the Universal Orlando Attraction Halloween Horror Nights 23in 2013.
