Prince Gumball
Prince Gumball (Full name: Bubba Gumball and previously known as (Prince Blowpop)) is the male version of Princess Bubblegum originally created by current series designer Natasha Allegri. After the gender-swapped characters were introduced in series of drawings and comics, they were featured in the season 3 episode "Fionna and Cake." Like Princess Bubblegum, Prince Gumball also has his own loyal companion, Lord Monochromicorn. Prince Gumball has shown romantic feelings for Fionna, but that was actually the Ice Queen in disguise. However, the real prince did show feelings for Fionna. However, Fionna decides not to try for a relationship, but admits the Ice King is totally hot, with Cake agreeing. It is later revealed the whole episode was the Ice King reading his own fan story with a trapped Finn and Jake forced to listen.
