10 Terrifying Batman: The Animated Series Episodes That Gave You Nightmares

10. Moon Of The Wolf

Werewolves are scary, plain and simple. When done properly, they can be absolutely petrifying and this just so happens to be one of those times. It begins with the classic "man walking his dog alone" trope to introduce the Wolf Man in a violent and primal way, though Batman does come in and an all-too-standard fight scene ensues.

One of the benefits of animation is that the transformation sequences aren't hindered by budget, for the most part, and the censors are a bit more lenient about showing it. When Romulus the Wolf Man first transforms, the screams and horror - shown both in the shadows and straight to camera - is frightening in an old school monster movie way.

While the quality of the episode itself has placed it on several worst lists, the Len Wein penned script brings a good, if standard, Universal-esque horror feeling to the series.
