Demons, poltergeists, and Frankenstein-like creations don't just make great costumes — they make great characters, too. Not all monsters in anime are horrific; some anime have a diverse range of monsters with more cartoony, Halloween vibes than straightforward horror. Their cast of characters comprising vampires, ghosts, ghouls, and zombies are like a love letter to "The Monster Mash" and make year-round entertaining watches.

Sometimes, the protagonist is an unwitting human who serves as a foil to the supernatural that surrounds them, while other monster anime are full of sympathetic, humanized monsters. Some titles really lean into seinen-level horror, while others are more lighthearted, like The Munsters meets anime.
