Which cartoon character do you find the most scary? Without it intending to be, that is? Personally, The Toon Monsters from yu-gi-oh! creep me out to insane levels. Particularily Mimicat... Their faces get so damn contorted... Anyway, what's your fear that you shouldn't be fearing? Fluttershy? Mr. 2? Villager no. 42?
Yeeeeaaaaah, for me... the coachman from Pinocchio, although intentionally scary, when he made this face [link] he scared the hell outta me beyond aaaaany expectations I've had, and I was already sufficiently creeped out by the puppeteer
It seems like a lot of people are mentioning intentionally scary characters.... Anyway, not technically a cartoon, but a puppet... thing. On Allegra's Window ... Well all the puppets are actually pretty creepy, but that cat and dog are horrifying.
"Night Of The Wheremole", blond violin girl and that puddle woman from Courage The Cowardly Dog; Higurashi no naku koro ni (full of scary scenes) and probably Paranormal Activity (I only watched part 1).
Definitely, the episode of 'King Ramses' Curse' on Courage the Cowardly Dog. I couldn't sleep blissfully for the coming week because of watching that ghost!
Here's a link to the YouTube clip of the episode, but warn you, it's still that scary: www.youtube.com/watch?vmC7gNU0CJgShare
