Prince Gumball

Prince Gumball (previously known as Prince Blowpop ) is the gender swapped version of Princess Bubblegum originally created by series character designer Natasha Allegri. After the gender-swapped characters were introduced in series of drawings and comics, the creators of Adventure Time decided to include them in an upcoming episode in season 3. Like Princess Bubblegum, Prince Gumball also has his own loyal companion, Lord Monochromicorn, whose color scheme is monochromatic while his counterpart, Lady Rainicorn is multichromatic.

Appearance
He has the same color scheme as his female counterpart but leans more towards a reddish hue. His hair is somewhat in a quiff, and his head adorned with a small yellow crown with a blue jewel. He wears a hot pink shirt with light pink puffed sleeves, a belt with a candy design on the buckle, pink striped trousers and dark pink shoes.
