We come to expect some inter-franchise face-offs in fan films, whether it's Batman vs. the Terminator or Batman vs. Wolverine. However, it's unlikely anyone saw this coming: Dexter Morgan vs. the Dark Knight.
Directed by Mike Donis, "Batman vs. Dexter: Crossing Over" brings the vigilante serial killer to Gotham City to abduct Oswald Cobblepot in an effort to draw out the Caped Crusader, simply to find out whether he actually exists. It's a solid enough premise that actually comes off pretty well, despite, as Topless Robot notes, the decidedly low production values (Batman's costume is particularly rough, and we're left to wonder why one of The Penguin's henchmen is wearing a Court of Owls mask).
The roughly seven-minute short is labeled "Episode 1" and ends on a bit of a cliffhanger, which certainly suggests we'll be seeing more of "Crossing Over."
