1 Blue Fetus Thing (Courage the Cowardly Dog)
Courage the cowardly dog could be too scary for kids
Man is courage first dream in perfect scary
Anything from this show is terrifying.
2 Him (PowerPuff Girls)
Him is a good character. But he's no match for mojo jojo.
His voice is more scarier than his appearances.
She/he's so scary they didn't give 'him' a name
3 Red Guy (Cow and Chicken)
4 King Ramses (Courage the Cowardly Dog)
King Ramses is in my opinion the scariest cartoon characters ever
How the hell is king ramses not in the top 5
5 CatDog (CatDog)
Just because he's a "freak", doesn't mean that he's scary.
American cartoons went strange in the 90s.
CatDog isn't scary.
6 Arnold's Cousin (Hey Arnold!)
Arnie is really weird. No wonder his first appearance was in an episode called "weird Cousin".
Arnie is not that weird.

How I thought it went.Boss: O right people, we need ideas for a villain for gravity falls. Have any ideas. Employee: How about a triangle. Everyone: laughs. Boss: okay okay why the heck would you think he would be a good idea. Employee: he has one eye, wears a top hat and bow tie and has the ability to shuffle someone's face, mess with time, gravity, and physics, make people insane, turn people to stone, distort the intro of the show and create unholy abominations and only desires chaos, death, and creating a throne of misery of frozen people. Everyone: gasps and one of them walks out of the room. Boss: an...anyone have any other ideas. No. Then this villain will do then.
He tortures kids, blackmails, drives people insane... in short I'd never put HIM on my guest list...
Discord's worst nightmare: a rival with creepypasta material
He may be funny but also creepy.

17 The Groke (Moomin)
The thing that scared me was the sounds it makes
18 Black Goku (Dragon Ball Super)
19 Dr. Robotnik (Sonic SatAM)
20 Billy (The Grim Adventures of Billy & Mandy)
How exactly is Billy scary? That is, unless he's perceived as scary by Grim, considering he and Mandy are probably considered the bane of his existence.
I guess his stupidity is scary?
