"Everybody loves monsters." This quote from former Doctor Who star, Peter Capaldi, is right on the money, which is why the anime world is filled with some of the creepiest, most horrifying creatures of the night. Monsters are among the most fascinating characters of fiction. It's entertaining to see their apathy, barbaric atittudes, and their hideous appearances. People love a good, scary monster to scream at, like those in the most violent Japanese OVAs.
Anime monsters don't skimp on the nightmare fuel. All the scary anime characters on this list have a large appetite for blood, guts, and destruction. They have a fetish for torture or a strong desire for survival. Not every monster is the typical ugly, bulky demon. Scientific or supernatural, these scary anime monsters are guaranteed to keep you up all night. Hold on to your bed sheets as you read about the scariest anime monsters of all time, and vote up the most terrifying, dark creatures that stalk the night.
Parasites - Parasyte: The Maxim
Always go to bed with your headphones on. That's the message of the day, brought to you by Parasyte: The Maxim. In this sci-fi horror anime, wormy aliens called Parasites crawl into the ears of people to assimilate with them. Parasites pull an Invasion of the Body Snatchers by completely erasing their host's identity. Those who possess humans develop a hunger for other humans. They also hunt Parasites that failed to completely assimilate with their host. If you feel something funny in your ear during bedtime, it's already too late.
Titans - Attack On Titan
It's pretty evident why the Titans from Attack on Titan would rank among the most scariest anime monsters around. Nude giants with the freakiest of faces, they run amok and devour humans like they're hors d'oeuvres. Even walls of crazy heights aren't enough to protect humanity from these unsettling creatures, which is why the post-apocalyptic world of Attack on Titan is one of the most dangerous anime locations in history.
Ghouls - Tokyo Ghoul
In Tokyo Ghoul, on the surface, ghouls are no different from human beings. They look like everyday Joes and Janes. However, their taboo hunger for human flesh make these anime monsters absolutely frightening. A Ghoul's cannibalistic diet cannot be avoided. The taste of normal foods literally makes them sick to their stomach and starvation will only drive them mad. On the plus side, they only need to eat every month or two and can still enjoy the rich taste of Folgers coffee.
Boar Demon - Princess Mononoke
Nothing gets the blood pumping faster than being chased by a demonic pig. In the shockingly violent Studio Ghibli film, Princess Mononoke, a tremendous boar becomes a wild demon, demolishing everything in his way. The boar's flesh rots as a swarm of crawling demon worms engulf his body, acting as an armor for its host and forming tentacles to attack. It's a beautifully animated scene of such a hideous beast.
