Complete Monster: The aforementioned Mephisto returns from the first film. As Roarke, he reveals that in order to walk on Earth he needs a human body; not only does this limit his power but his current body is now dying. Among his previous host bodies were Josef Stalin, Idi Amin, and John Wayne Gacy. To create a permanent and powerful host body, Mephisto conceived a child with Nadya Ketch. It's also revealed that in order to create the Ghost Rider, Mephisto dragged Zarathos, the Angel of Justice, into hell, torturing and twisting him into insanity. When Nadya and her child Danny escape, Mephisto masterminds a demonic conspiracy of murder to get his hands on Danny in preparation to destroy the boy's soul, possess him and bring about the Anti Christ. When Johnny, Nadya and Moreau disrupt this ritual, Mephisto makes a final attempt to flee and abduct Danny before his final confrontation with Ghost Rider.
Contested Sequel: Either the movie was an improvement over the previous movie or the worst of the two films.
Why is the Rider so incredibly psychotic in the film? Johnny's been keeping him locked away. He hasn't had any fun in a long time, and suddenly he's been given carte blanche to do whatever it takes to find Danny. Let the slaughter begin!
Could also explain why Johnny himself acts so absolutely friggin' nuts through the whole movie, and actually seems to calm down during the period when he's de-powered. It's repeatedly said that the fallen angel that inhabits him is literally insane.
The Rider's line in the first trailer released on-line also shows that in addition to being completely out there in terms of his brutality, he also has a disturbed sense of humor when he kills someone.
