So Nostalgic, It's Villainous.

Maliphicent, the dark fairy. This badass bitch taught me that sometimes, it's better just to sleep in. (Sleeping Beauty 1959)

Professor Screweyes, and his Eccentric Circus. This guy combines two of my most irrational fears. Ommatophobia and Ornithophobia. (We're Back! A Dinosaur Story 1993)

The Grand Duke of Owls aka Uncle Dukie. This bastard got me so scared of the dark I would hoard batteries and leave a flashlight on under my pillow. Seriously. (Rock-a-doodle 1991)

Padraic Ratigan, the burden of Baker Street. Talk about Dr. Jeckyll and Mr. Hyde. A smooth talking mob boss, with the savagery one would expect from a hulking sewer rat. Plus they said his name so creepily. (The Great Mouse Detective 1986)

The Nightmare King. His name should be enough, but this shapeshifting demon can seriously fuck right off with his bullshit. Normally seen as a black cloud of claws and teeth, he's the reason I don't let my feet dangle off the bed. (Little Nemo Adventures in Slumberland 1989)

Nightmare King cont.

Chernabog aka literally Satan. Probably the biggest, baddest, and most evil thing ever animated for a kids movie. I remember sitting through the movie bored outta my gourd, just waiting for this guy so I could "conduct" with him. He was my Elsa. (Fantasia 1940)

Claude Frollo, The Judge. Ruthless, self-righteous and religiously pious. He has an intense hatred of the gypsy population and seeks to annihilate their entire race. He's basically Hitler. (Hunchback of Notre Dame 1996)

The Grand Owl. Ok, so not an actual villian, but definitley nightmare fuel nonetheless. In fact, this whole movie is nightmare fuel, and I just hate birds. (The Secret of NIHM 1982)

Hellhound. This is one of those scenes that I didn't really understand as a child, but it creeped me the fuck out anyways. He appears twice in the movie and isn't even the main antagonist, but this ending scene is forever scarred into my childhood. (All Dogs Go To Heaven 1989)

The Great Animal. Half Beast, half bat, all terrifying, this creature is the commutation of a Warlock who curses the princess in hopes of a forced marriage. There's a bestiality joke in here somewhere, but I'm too frightened. (The Swan Princess 1994)

The Horned King. Finn the Human ain't fucking with this Lich. He has a massive army of ghouls, monsters, a dragon, and his "cauldron born" which are basically wraith kings. He just wants death, pure and simple. (The Black Cauldron 1985)

This was a short glimpse at some of my favorite villains from childhood. I hope you enjoyed!
