Princess Bubblegum

Princess Bubblegum (full name Princess Bonnibelle Bubblegum, often abbreviated PB, or even Peebles) is a main character in the Animated Short, as well as in the series Adventure Time. She is a human-bubblegum hybrid, the benevolent ruler of the Candy Kingdom, and the main love interest for Finn. Her first name is Bonnibel, according to Marceline. At the end of "Mortal Recoil" she was transformed into a 13-year-old, but returned to her normal age of 18 years old in "Too Young."

Appearance
Princess Bubblegum dresses as a traditional princess in a flowing, pink gown and a gold tiara with a turquoise stone at the top. Her skin is usually colored lavender or lilac. Her "Bubblegum Pink" hair is made of bubblegum, as she is a hybrid of human DNA and bubblegum. A scientist at heart, Princess Bubblegum is often seen wearing a white lab coat and goggles when she is performing experiments or solving equations. Princess Bubblegum has at least fifteen outfits. These outfits range in color and style from an orange T-shirt and white shorts to a fluffy, powder-blue dress and pink cardigan.

As a thirteen-year-old, she wears a white dotted V-neck top with puffed sleeves and a ballgown bottom with a big, purple ribbon around her waist. While her hair is shorter and curls up at the bottom, her tiara remains the same. As shown in "Too Young," she doesn't wear any shoes. When she turns back to eighteen, her outfit also changes back to her original one.

Personality and traits
Princess Bubblegum is an amiable, benevolent ruler. She loves (most of) her subjects unconditionally and has been known to defend them tirelessly when trouble brews. Even beyond her own domain, Princess Bubblegum possesses a strong sense of morality and participates in politics outside the Candy Kingdom.

Princess Bubblegum is a highly cultured and educated ruler with an undying passion for science. In "Slumber Party Panic," she attempts to revive the dead Candy People, accidentally creating a horde of zombie Candy People instead.

Though ordinarily sweet and good-natured, Princess Bubblegum shows a malicious aspect of her personality whenever she is crossed, as toward the Duke of Nuts for eating all of the royal pudding and believing him to have ruined her appearance. Also, in "What Have You Done?," she displays a cruel willingness to torture Ice King.

When she was 13 years old, she shows a more playful attitude, with a willingness to perform pranks with Finn.

Finn
Princess Bubblegum is Finn's primary love interest. Though seemingly unaware of his love, Princess Bubblegum cites the hero as a great friend and will never hesitate to call on him for aid in royal matters. Finn and Princess Bubblegum share the same moralistic nature, and often work together to right any wrongs in the Land of Ooo.

The princess sees Finn as her "flawless champion," as said in The Duke, and also shown in The Duke, that there is a picture of Finn on her walls. She invests a lot of respect and faith in the young boy. In "To Cut a Woman's Hair," she said, without doubt, that she likes Finn, although it can just mean she likes him as a friend. Although he sometimes angers her, Princess Bubblegum never holds a grudge against Finn. In "The Real You," she gives Finn a kiss on the cheek for saving the Candy Kingdom from the black hole he created. In "Go With Me," though she exiles Finn from the Candy Kingdom after he releases a pack of wolves into her room, the resentment is only temporary because Princess Bubblegum appears to have forgiven Finn by her next appearance.

In "Mortal Folly," she said to Finn, "I care about you," and gives him a pink sweater with a white heart stitch to the left that she made with the power of "liking someone a lot" which ended up helping Finn defeat The Lich. In "Mortal Recoil," Princess Bubblegum ages down to 13. Finn comments that that's how old he is and blushes as the new younger Princess Bubblegum says, "Give me a hug, hero."

In "Too Young," Princess Bubblegum acts very loving and affectionate toward Finn during the time she is 13, even going on a "date" with him, leaning on his shoulder, holding his hand, etc. She expresses a bit of regret when she has to turn back to 18 because she never gets to "act like a kid." She also says to Finn that she would rather "stay here, with you." During the transformation of her being back to 18, they share a brief kiss. When she changes back to 18, she returns to her normal personality, without the same kind of affection for Finn. When Finn asks whether they could "hug some more," she replies with "That was like 5 years ago, you need to move on." Of course, she makes this remark with a smile and mutters something about him being a 'silly boy' as she walks back into the castle.

Finn has a few nicknames for her, such as PB, Princess, Bubblegum, and Peebles (Finn sometimes pronounces it as "Poibles" or Preebos").

Lady Rainicorn
Lady Rainicorn is Princess Bubblegum's mighty helper and one of the creatures seen to have provided transportation when needed, alongside her swan and The Morrow. In "Video Makers," she is seen talking to her before Finn serves the drinks, meaning that Princess Bubblegum may be able to speak Korean or just understand her in a way similar to Jake. Lady is half unicorn and half rainbow, she also has love of the viola that her boyfriend Jake plays.

Marceline
In the original pitch documents, Princess Bubblegum and Marceline are shown to be friendly rivals. Though having been in the same place at the same time in several occasions, their relationship with one another wasn't fully disclosed until "Go With Me", where we see Marceline trying to be civil towards Bubblegum while the princess shows rather displeasure in being around her. Bubblegum's perspective makes her see Marceline as wild to the point of corrupting Finn into being exiled out of her kingdom, showing that she tries to minimize contact with her as best as possible. Bubblegum sees Marceline as wild and crazy, and Marceline sees Bubblegum as boring and stiff. Bubblegum is generally a woman of grace and poise but in Marceline's presence she begins talking in a sarcastic tone and acts on jealously, which is rather unlike her.

Lumpy Space Princess
Lumpy Space Princess is mostly Princess Bubblegum's best friend. Despite their drastically different personalities, the two are often together and L.S.P. is a frequent visitor to the Candy Kingdom during many of its parties and ceremonies. In "Video Makers," PB takes L.S.P's seat and she gets mad at her, but that's probably L.S.P being herself.

Duke of Nuts
Princess Bubblegum has an outright hatred for the Duke of Nuts. Though this is all explained to be a relationship between the two in "The Duke", Princess Bubblegum still loathes the Duke and distrusts him because he eats all the royal pudding.

Ice King
As one of the main characters in the series, Ice King particularly has targeted his time to capture a princess to marry, he mostly targets Bubblegum. Bubblegum takes great annoyance with Ice King's actions but generally seems to put up with it, mostly due to having Finn around to rescue her whenever he targets her. One of the few times that Bubblegum showed particular anger towards Ice King was in "What Have You Done?," mostly due to Ice King's attempt at a kind gesture to make it snow ends up making nearly the entire kingdom sick, forcing her to make Finn and Jake capture him at all costs, even without telling them why she wants him imprisoned.

In "Mortal Folly," Ice King's obsession with Bubblegum nearly leads to the destruction of Ooo due to capturing her just as Finn fought The Lich, leading to her being dropped by him into his evil power source. Yet he still was loyal enough towards her to help save her life after her broken body was possessed by The Lich to destroy Ooo. It is unknown if Bubblegum's age change as of "Mortal Recoil" had presumably temporarily changed his interest towards her, since as she turns 13 he leaves through the window saying "Ah, dang it! Well, I'm out of here. Goodbye everybody,". However, since her return to the age of 18, he is once again interested, as seen quite clearly in Wizard Battle.

Biography
Princess Bubblegum is the beloved ruler of the Candy Kingdom. Though not much is said about her past, it is known that many of her relatives are famous (suggested in the episode "Susan Strong"). It is implied that Finn has saved Princess Bubblegum many times (and vice versa as seen in the episode "Dungeon"). It also seems that she has had previous run-ins with Marceline, the Vampire Queen (possibly from childhood).

She spends most of her time in Ooo sending Finn and Jake on different quests that generally vary in difficulty. In the first part of season two's two-part finale, "Mortal Folly," she sends Finn and Jake on a quest to stop the evil Lich from killing everyone in Ooo. She gives Finn "The Gauntlet of the Hero Billy" as the weapon necessary to destroy him once and for all. The first part ends with Ice King, who decides to capture her until Finn and Jake give him their blessing to marry her, accidentally dropping the Princess into a fiery, green pit. She is soon melted into a pile of pink-brown goo.

The second part of the two-part finale, "Mortal Recoil," opens with Finn, Jake, Ice King, the Candy People, and other princesses going with her as she is rushed to the hospital. It is soon revealed that the spirit of The Lich possessed the princess earlier and eventually warps her into an eldritch abomination that nearly tears apart the Candy Kingdom. Finn realizes that his 'like like' of the Princess might not be enough to save her and the Kingdom, so he enlists the power of Ice King to immobilize her. Unfortunately, the frozen princess topples over and smashes to pieces. The doctors reassemble her, but lack all the necessary pieces, reducing her age to 13, the same age as Finn. When Ice King realizes she is now underage, he loses his interest in Princess Bubblegum.

However, when the Earl of Lemongrab comes to usurp her throne, she is forced to restore herself to her 18-year-old form with the contribution of biomass (candy) from the Candy People and a hug (and kiss) from Finn. After reverting to 18 in "Too Young," she jokingly acts as if the events of being 13 were "five years ago."
