Princess Gumball

Princess Gumball is the gender-swapped version of Princess Bubblegum. He was originally created after the gender-swapped characters were introduced in a series of drawings and comics, and then they were featured in the season 3 episode "Fionna and Cake," in which it is revealed that the characters only exist in fanfiction written by the Ice King. Like Princess Bubblegum, Prince Gumball also has his own loyal companion, Lord Monochromicorn, and can understand his Morse code. In the spin-off/sequel series Fionna & Cake, it was revealed that many characters from the original series, including Prince Gumball, are real in a secret alternate reality created by Prismo, but they were turned into non-magical and human versions of themselves. His human version is called Gary Prince, working as a barista and pastry chef.
