Charlie is a dog/shape-shifter/rainicorn hybrid and is one of Jake and Lady's five children.
Charlie resides in an ancient temple on the far side of the world and travels to Ooo by growing to a massive size and becoming intangible, then easily walking through the ocean with her upper half out in space. She is heavily into mysticism and Tarot cards, which she uses to read the nature of others. In "Daddy-Daughter Card Wars," she uses one of Jake's bones and a lock of Lady's hair to read her own future, which depicts her going through some periods of confusion and sadness, but ultimately winding up content in her 90s. At some point, she may be destined to have a hybrid son she names "Gibbon."
