Damien was originally going to be voiced by Beavis and Butt-Head creator and voice actor Mike Judge. Due to the fast production of South Park, however, Judge was unable to record new lines. He later recorded lines for Kenny McCormick's unmuffled voice in South Park: Bigger, Longer & Uncut.

Cartman's beloved Mega Man toys are a parody of the Power Rangers franchise, a series of live-action superhero television programs which recycle footage from the Japanese Super Sentai series.
The helmets on the Mega Man toys resemble those used in the 1990 Super Sentai Series, Chikyuu Sentai Fiveman.
The name "Mega Man" also belongs to a famous video game character created by Capcom. The toys Cartman receives looks nothing like it, however.
Mega Man also references other toys of Japanese origin; Transformers (1977–present) Voltron (1981-present).
Damien's theme music is a parody of the "Ave Satani" theme from the film The Omen. The name Damien is another reference to the Omen films.

Stan inspires Jesus with the quote "Don't try to be a great man, just be a man", and tells Jesus that he said it himself. When Kyle asks if it's true or not, Stan admits that he heard it on Star Trek. The line is from the 1996 film Star Trek: First Contact, said by the character Zefram Cochrane.
When Damien makes demons throw Pip into the air and make a fireworks display out of him, it's similar to the scene in Dragon Ball Z where Vegeta kills Cui with an attack known as Dirty Fireworks.

The referee of the boxing match is a parody of referee and judge Mills Lane.
When Stan tries to give Jesus a pep-talk and encourage him to give the fight his best, he cites figure skater Nancy Kerrigan. Kyle sours that motivational speech by mentioning that she won the silver medal. This is a reference to the 1994 Winter Olympics, in which Kerrigan was beat for the gold medal by 0.1 points.
