Lady Rainicorn

is a unicorn-rainbow hybrid. She is Princess Bubblegum's pet and companion. She is also Jake's girlfriend, and sometimes follows Finn and Jake on their adventures. She speaks only Korean, using English only when equipped with a Universal Translator. Jake is the only other being in the Land of Ooo, besides Lady's parents, that is shown to understand Korean, though PB likely can understand her as well. Someday she and Jake hope to have mixed species kids.
