Some are American animation, some are anime, some would even be classified as hentai, But they are all great.
1. Fire and Ice
One of my favorite movies as a kid, I lost count of how many times I've watched it. It was made in 1983 and directed by Ralph Bakshi, All the characters were created by Ralph Bakshi.
It's high fantasy with swords and sorcery.Larn is cool, Teegra was the type of woman I wanted to marry, And Dark Wolf shaped the type of hero I like. Also, the first time I heard a cuss word in a cartoon, Blew my mind at the time
This film was made in 1988 and was directed by Katsuhiro Otomo, It was based on the manga by Otomo (which I've never read, sadly)
Features cyberpunk, cool ass bikes, super psychic powers, And some of the coolest animation ever. This one introduced me to anime and is still one of my favorites!
3. Peter Pan
Made in 1953 and a timeless classic about never growing up and becoming a fuddy-duddy.

Awesome fight scenes, awesome characters, awesome story, and some very hot animation!
