Adventure Time: Ranking Every Major Character From Worst To Best
10. Lady Rainicorn
Lady Rainicorn, as the name suggests is half unicorn, half rainbow and she plays a key part in the Adventure Time universe. She's Princess Bubblegum's best friend, as well as Jake's girlfriend and went on to become the mother of his children - a bunch of half dog, half rainicorns called Charlie, Viola, Kim Kill Whan, Jake Jr and T.V.
She's certainly one of the most unique characters, which is saying something considering how downright weird a show Adventure Time can be. She can fly, phase through matter, change the colour of things using her horn and she only speaks in Korean. There's very little bad to be said about Lady Rainicorn, but while it's great that she has made Jake so happy over the years, she finds herself low on this list due to a lack of truly memorable moments.
Sorry Jake.
