Red Pyramid is a full body costume that was blended at Roberto Campanella wrists, requiring only 25 minutes of preparation for each scene, as opposed to the three hours it took in the first film.

The cult shown in Revelation, despite being stated to be the same cult as in the first film, has an entirely different set of beliefs that is almost completely opposite to that of the original cult. The first film shows that Alessa Gillespie was burned alive as a witch, due to the cult believing that she was "sin incarnate" due to her being born out of wedlock. Revelation, however, states that the cult burned Alessa so they could perform a ritual to impregnate her with a physical incarnation of their god, knowing that she would survive the fire. Initially, M.J. Bassett claimed on her blog that the Order (the cult seen in Revelation) and the Brethren (the name given to the first film's cult) were two separate cults. However, this is contradicted by Vincent's statement in Revelation that the Brethren are the most fanatical members of the Order. Similarly, the religious symbol of the cult is changed dramatically between the two films, to the point of being unrecognizable.

After the end credits, Pyramid Head is seen walking and dragging his giant sword after defeating the missionary.
