Lady Rainicorn

Lady Rainicorn is a non-playable character in MultiVersus.

Context
Lady Rainicorn is one of the few Rainicorns that actually live in the Land of Ooo. She's Princess Bubblegum's royal steed and Jake's fiancée and, just like the rest of the Rainicorns, can only speak Korean unless she equips an universal translator device that lets her speak English as well.

Role in MultiVersus
Lady Rainicorn can be seen in the background of Tree Fort, flying periodically from left to right.

She can also be seen in the Jake's Pups Ringout VFX.
