Here are two Adventure Time papercrafts: Princess Bubblegum and Marceline, created by Niggayo. Princess Bubblegum (full name Princess Bonnibel Bubblegum, often called PB and on occasion Peebles, P-Bubs, or other nicknames) is a main character on the series Adventure Time that first appeared in the Animated Short. She is the benevolent ruler of the Candy Kingdom, and is Finn's former love interest. She is also Ice King's most often-targeted princess. Marceline calls her by her first name, Bonnibel. At the end of "Mortal Recoil," she was transformed into a 13-year-old, but returned to her normal biological age of 18 years at the end of "Too Young." She has a gender-swapped character named Prince Gumball created by the Ice King in a fan-fiction.
Princess Bonnibel Bubblegum is the beloved ruler of the Candy Kingdom. Though not much is said about her past, there are some allusions to her relatives. It is implied that Finn has saved Princess Bubblegum many times, though she winds up saving him in the episodes "Dungeon" and "Lady & Peebles." It also seems that she has had previous run-ins with Marceline, the vampire queen. In the past she created Lemongrab, then sent him away to live a sheltered life inside his own castle. Princess Bubblegum also performs other science experiments which vary from very successful to catastrophic.
In the second season's two-part finale, "Mortal Folly" and "Mortal Recoil," she sends Finn and Jake on a quest to stop the Lich from killing everyone in the Land of Ooo. She gives Finn the Gauntlet of the Hero Billy, as it is the only known weapon that can harm the Lich, and a sweater she made herself. The Ice King captures Princess Bubblegum and chases after Finn and Jake to get their blessing to marry her, but he accidentally drops the princess into a pit of green liquid. She is soon melted into a pile of pink-brown candy goo, and is rushed to the hospital.
It is soon revealed that the spirit of the Lich has possessed the princess and eventually warps her into a giant monster that nearly tears apart the Candy Kingdom. Finn enlists the power of Ice King to immobilize her with a very freezing ice. Unfortunately, the frozen princess topples over and shatters to pieces. The doctors reassemble her but lack all the necessary pieces to put her back together, reducing her age to 13. According to Adam Muto, her body was composed of only enough reclaimed biomass to be an adolescent, and therefore she turned into one.
As a 13-year-old, Princess Bubblegum is technically younger than the Earl of Lemongrab and he claims his right to the throne until she turns 18 again. After failed attempts of pranking the Earl until he leaves, Princess Bubblegum is forced to restore herself to her 18-year-old form with the contribution of biomass from the Candy People and a hug from Finn. After reverting to her proper age and size in "Too Young," she jokingly acts as if the events that happened earlier that same day actually happened five years ago.
In "Burning Low," Princess Bubblegum reveals that Flame Princess is physically unstable, and she prevents Flame Princess's Elemental Matrix from causing the end of the world: she guides Jake to block the hole resulting from the kiss between Finn and Flame Princess, thus cutting off Flame Princess's oxygen supply and stopping the reaction.
During the events of "Lady & Peebles," Princess Bubblegum and Lady Rainicorn track the missing Finn and Jake into an uncharted ice cave, with the belief that Ice King has captured them. After surviving dangerous encounters within the dungeon's environment, it is revealed that Ricardio set up the situation to lure Bubblegum into the cave and force her to marry him, tying Lady Rainicorn into a knot and having already poisoned Finn and Jake with Zanoits. Princess Bubblegum challenges him to a fist fight and defeats him by ripping his newly attached limbs away at their exposed sinews. She then drags Finn, Jake and Ice King back to the Candy Kingdom on Lady's back, creating a new heart for Ice King out of "Ricardio's sinews, toffee and maracas." She is also the first person to learn of Lady Rainicorn's pregnancy.
Princess Bubblegum patches up her rocky relationship with Lemongrab in "You Made Me!" by making him a Lemongrab clone, so he will have a friend who truly understands him. At the end of the episode, the princess bids them a fond farewell and they both invite her to visit anytime, indicating that the three of them are on good terms.
Marceline, the Vampire Queen (full name: Marceline Abadeer) is one of the main characters in Adventure Time and a vampire that is over a millennium old. During Finn and Jake's first encounters with her, she requests that they leave wherever they are as the areas belong to her. Though initially an enemy to them, she quickly becomes one of Finn and Jake's closest friends.
Marceline is described as a wild rocker girl. Centuries of wandering the Land of Ooo have made her a fearless daredevil. She is a lover of all things exotic and still travels the land often. She has a mischievous personality and is rarely intimidated. Despite seeming evil at first, Marceline is a trickster at heart, and her "evil plans" often turn out to be nothing more than elaborate jokes. She is described by Finn as "a radical dame who likes to play games." She loves to play pranks on Finn. She also might sometimes have violent outbursts, as shown in "It Came from the Nightosphere." Though during her line in the song, in Evicted! she stated that since she has been alive for over a thousand years she had lost her moral code.
She can also be sentimental. She was very emotionally attached to her teddy bear Hambo, which was given to her by Simon Petrikov; and after Ash sold it to a witch, she was furious and broke up with him.
Marceline seems to be a little emotional. For example, in "What Was Missing," she seemed to be more "aggressive" towards Princess Bubblegum than she usually is. She is also very independent, and in early episodes would often act without concern for Finn or his friends. It is easier for Marceline to express her feelings through music, as seen with "The Fry Song" and "I'm Just Your Problem," but has trouble expressing them otherwise. She keeps a diary that she uses for inspiration for songs as seen in "Marceline's Closet." When Marceline read the lyrics to "Remember You," the song that Simon Petrikov wrote for her, she began to cry.
Marceline has light blue-gray skin and long, midnight black hair that reaches to her feet. She also sports two marks on her neck which could be the bite mark that turned her into a vampire. Despite being over a thousand years old, her appearance and personality is that of a late teenager. In the episode "Go With Me," her hair is shaved into an undercut, which reveals that she has pointy ears. She is very thin and sometimes appears to be thinner than Princess Bubblegum; however, her shape can vary slightly depending on who is drawing her. She is usually floating in the air but when she stands next to the other main characters she is taller than them. [Source: wikia]
