Lady Rainicorn is a half-rainbow half-unicorn creature, as well as Jake's girlfriend and Princess Bubblegum's companion. She can turn objects and people different colors, and she can fly because her body intercepts light and can "dance" on it, which also explains her movement and why she has a rainbow pattern. She grew up in the Crystal Dimension, and spent her early years dating a dog-hating rainicorn named Lee. Eventually, she saw the error of her ways and escaped to Ooo.
