It's a Gate to Hell, Cecilstein! (2006)

Our hero is Cecil Stein (although his friends call him 'Cecilstein') who wakes up one morning to find that a gateway to the fiery pits of hell has opened up under his bed. A demon takes control of him and compels him to steal babies that he can feast upon. He tells Cecil that a hell-born apocalypse will befall the earth if he doesn't comply. Tapping into Cecil's love of comic books, the hideous demon convinces him that he will be a superhero and gets him to decide on a costume. He chooses a Frankenstein mask and sets out on a baby-napping mission...
