Top 10 Most Intense Scooby Doo Monsters

This is actually scary. This is real for once, actually kills people, and an evil, heartless demon.

This thing is a psycho. Like seriously, it wanted to destroy the universe.

How many times would someone see an evil entity in one day?

It killed everyone but the gang.

God they were scary.

Which one do you mean? The Mayor Jones Freak or the Dream World one?

Really, I don't know how to explain it, he is just scary.

This is above all of you, if the darkest and scariest

A monster from the dream worlds is very creepy...

Reminds me of my friend John. He wears a tingle costume and flops around on the floor

An evil, mythical, goat like boogeyman? Creepy.

This demon has layers of teeth, and wants to take a secret soccer ball that has a weird ingredient in it.

If you can say it's a little scary

A very well known monster.

Wow, this guy is pretty creepy now that I think of it...

This gave me nightmares as a kid

Surprisingly enough for being so creepy, he was also the first example of a good guy in costume

A ghost in a diver's suit, underwater, with No face?!?

One of the 13 demons in the chest, he is a no faced cloak floating around, however, he does have yellow eyes.

These things made me scared to sleep at night as a kid.

Zombies with no faces, plain creepy.

In the end, he turns out to be a real ghost. (There is another version of him though, George Avocados disguise)

This guy is pretty scary, and unusual.

A gnome should be funny and cute. This one freezes people in a blistery red crystal casing. Pretty creepy.
