Prince Gumball is the gender-swapped version of Princess Bubblegum originally created by the current series designer, Natasha Allegri. After the gender-swapped characters were introduced in a series of drawing and comics, they were featured in the season three episode, "fionna and Cake". Like Princess Bubblegum, Prince Gumball also has his own loyal companion, Lord Monochromicorn. Like PB understands Korean, he can also understand the morse code. Prince Gumball has also shown romantic feelings for Fionna, but that was actually the Ice Queen in disguise. Although, the real prince also has shown feelings for Fionna as he has asked her out on a date.
