Prince Gumball

Prince Gumball is the gender-swapped version of Princess Bubblegum. He was originally created after the gender-swapped characters were introduced in 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. Just as Princess Bubblegum can understand Lady's Korean, Prince Gumball can understand Lord Monochromicorn's Morse code. Prince Gumball has shown romantic feelings for Fionna, but that was actually the Ice Queen in disguise. However, the real Prince Gumball also shows feelings for Fionna and had actually asked her out on a date.

Appearance
Prince Gumball has the same color scheme as his female counterpart. He has pink skin and his hair is somewhat in a coiffe. His head is adorned with a small golden crown and a blue jewel. He wears a hot pink shirt with the top being purple along with light pink puffed sleeves and magenta slits. He also has magenta under-sleeves (accompanied by dark-pink sleeve cuffs) and a large matching collar with a small blue jewel inside a gold crest on it. He has a belt with another golden crest and a small blue jewel design on the buckle, dark-pink trousers with purple seams running down the sides, and indigo-violet dress shoes. Unlike his female counterpart, he has visible pink eyebrows. Also, when his eyes enlarge, they are shown as purple.

Personality
Prince Gumball is the beloved ruler of the Candy Kingdom. He loves almost all Candy People. He is an elegant young man who is formal and intelligent.

Major appearances

 * "Fionna and Cake"

Minor appearances

 * "Bad Little Boy"
 * "The Prince Who Wanted Everything" (non-speaking cameo)

Fionna
Fionna has shown romantic feelings for Prince Gumball. He asked her out on a date, but then Ice Queen captured him, and in his room at the palace during the Biennial Gumball Ball, he was saved by Fionna.

Lord Monochromicorn
Lord Monochromicorn is Prince Gumball's trusty steed, like how Lady Rainicorn is Princess Bubblegum's royal steed. He transports Prince Gumball when racing Fionna and Cake. They appear to be as close as Fionna and Cake.

Ice Queen
Ice Queen tries effortlessly to capture and marry princes. Her most targeted prince is Prince Gumball as he is her main love interest and competes with Fionna, just like how Ice King's most targeted princess is Princess Bubblegum.

Marshall Lee
Since all appearances of Marshall Lee and Gumball have been stories told by different people it is unclear if the portrayal is supposed to be consistent or if it simply varies with each author.

By Ice King
In "Fionna and Cake" Marshall does seem to be invited to the Biennial Gumball Ball.

By Marceline
Marshall Lee and Prince Gumball are shown to be about on the same terms as Princess Bubblegum and Marceline in "Bad Little Boy." Prince Gumball called Marshall Lee "uncivilized company" and went back inside when Fionna chose to talk to Marshall Lee instead of him.

By Gunter (Fionna and Cake comics)
Lee and Gumball are depicted as close friends and are stated to spend time with each other on a regular basis, often together with Fionna. Fionna thinks they are "cute pals" and in one scene she and Cake mistakenly assume that they are about to confess being a couple.

Prince Gumball's bedroom
Prince Gumball's bedroom is the place where Prince Gumball presumably sleeps. Parts of the floor were destroyed when Ice Queen used her ice magic to make ice come from the floor and attack Fionna.

Appearance
Prince Gumball's bed is purple with a pink bed frame. There are three purple pillows and a red blanket. It has a carpet that goes up the steps where his bed is placed. It has some candles and a flower pot. There is a door that goes to an unknown room. There is also a pink bean bag in the corner with what appears to be a ukulele laying on it, and a lamp hanging over it for light. Like a typical royal bedroom, it has two castle-like windows to each side of the bed. Near the ceiling, there are many round pink drapes, there is also one drape that extends far beyond the others. There are rose petals scattered over the room. It is unknown whether they are usually there, or if he only scattered them to "welcome" Fionna.

Trivia

 * Unlike Princess Bubblegum and Marceline's relationship, which in Marceline is the only one to call her by her first name, Marshall Lee is never shown to even call him by "Prince Gumball". He simply calls him either a sarcastic "your majesty" or a wad.
 * His name was changed from "Prince Blowpop" to "Prince Gumball" because "Blow Pop" is a brand name. . However, the name is still used in some older comics and pictures prior to the name change.

 * Ice King states in The Adventure Time Encyclopædia that Prince Gumball likes science
