Flame Princess

Flame Princess, whose name is Phoebe and who is occasionally called FP, is the current ruler of the Fire Kingdom as well as Finn's ex-girlfriend. When Jake asks Flambo if he knows any princesses that are Finn's age so he can fix his broken heart, he introduces Jake to Flame Princess. Flame Princess was locked away in a lantern in the main chamber of the Fire Kingdom when Jake first encounters her. It is later revealed that her father, the Flame King, put her there on Princess Bubblegum's advice when she was an infant, and she did not come out for 14 years. She has a short temper, trust issues, and a heat core that can destroy the world if overblown with emotions. She is also now close friends with Cinnamon Bun. Due to the events in "Princess Day," she is considered a registered princess.

As revealed in "Elemental", she is the current Fire Elemental.

History
As an infant, Flame Princess was chaotic and free spirited—she was even said and proven to be more powerful than her father, Flame King. After hearing this, the King ordered a messenger to send his daughter away from the Fire Kingdom to "wander into the outside world to perish." She was left in a nearby forest with a Crystal Lumberjack, but wandered away laughing and burning her surroundings. When Flame Princess wandered near the Candy Kingdom, Princess Bubblegum noticed this and, while wearing a fire suit, returned her to the Fire Kingdom. Once there, Bubblegum told Flame King to keep his baby under control or that she would do so herself. Flame King initially denies having a daughter, but admits his parentage when Bubblegum insists that he take her back. They come to an agreement and decide to trap the royal baby in a giant lantern for the rest of her life to ensure that she could never usurp her father's position in the Fire Kingdom. Despite this, she seems to have made friends and grown up talking to Flambo through her lantern.

It was not until fourteen years later in "Incendium" when she was allowed to be released by her father after Flambo finds her a boyfriend. It is believed that Flame Princess was a handful as a kid despite growing up in a lantern as Flame King described her as "totally evil and destructive." Even so, she was only released because he believed that "Prince Finn" was a cold-blooded killer who would suit his daughter perfectly. After leaving the Fire Kingdom to be with Finn, she resided in the grasslands inside a fire hut—no longer wanting to be influenced by the evil of her kingdom.

Flame Princess discovers that her emotions are unstable and can destroy the world from the core in "Burning Low" when Princess Bubblegum tries to stop her from kissing Finn due to the burst of intense romance. Finn and Flame Princess, on the other hand, want to become more physical in their relationship. Despite the danger they impose on the world, Finn ignores it and risks kissing Flame Princess—almost destroying Earth's core. This near total-fatal event strengthened the bond between the couple and also made Flame Princess more aware and cautious of her emotions and elemental powers, despite still not fully understanding how to control them.

Meanwhile, Flame King believed his daughter was pure evil and had intentions to drag her down again. Once he found Flame Princess's new home and began haunting her with evil whispers, she was frightened and feared that she was truly evil and could not fight her blood. She kept this to herself for a while until she finally came clean to Finn, so he took her on a quest of heroes to prove to her she is not evil and shift her alignment to good. This made her happy and no longer scared of her past or her family, as she was good at heart. She begins having dinners with "the less evil side" of her family and occasionally her father, as well as regular adventures with Finn and Jake.

As her relationship with Finn played out, they began going on dates and picnics. One of these picnics was interrupted when a fight between Flame Princess and a passing-by Ice King breaks out, causing Finn to have a strange dream. Realizing the fight is what caused the dream, Finn caused another fight by writing both Flame Princess and Ice King a rude letter from the other. Although he had the dream again, Cosmic Owl appeared and told him that "You [He] blew it." This confirms that Flame Princess is indeed important and has an unknown special link to Ice King and the Cosmic Owl. Waking up from the dream and discovering that Flame Princess has destroyed the Ice Kingdom and nearly killed Ice King, Finn stops the fight and confesses he was the one who wrote the letters because he needed to see the dream again and learn what it meant. Flame Princess breaks up with Finn, hurt that she was used so flippantly and by the fact that the letter contained very personal information that Finn wrongly used against her, breaching their trust.

After her break up with Finn, Flame Princess has trouble controlling her emotions and powers again, claiming she does not want to feel that way as Princess Bubblegum observes her. Not remembering that Bubblegum was the one who locked her away as a child, Flame Princess befriends the fellow princess and allows her to run test on her so she can understand herself better. While talking to Cinnamon Bun when Princess Bubblegum leaves Flame Princess unattended, he tells her that Bubblegum is evil. Flame Princess is shocked and questions him, so he reminds her that when she locked her in the lantern as a child was pretty evil. Flame Princess then has a flashback and remembers what Bubblegum and Flame King did to her, recalling why she grew up in a lantern in the first place. She then has an outburst after discovering the betrayal of another friend, screaming "Is everyone hiding something?!" The princess then sets off, back to her kingdom for the first time since she left it behind her.

After returning home, Flame Princess realizes she is more powerful than her father and overthrows him—putting him into the lantern where he trapped her during her past life and becoming the new ruler of the Fire Kingdom. She brings her only true friend Cinnamon Bun with her as he leaves his Candy Kingdom days behind to become the princess' new servant. Flame Princess claims she will not be sucked back into the evil, and she makes "honesty" the new rule of the Fire Kingdom. When Bubblegum learns that Flame Princess and Cinnamon Bun left, she becomes outraged and goes with Finn to track them down to the kingdom. Flame Princess tells them that she overthrew her father to enact a new regime of honesty within the Fire Kingdom. Stating that her place is in ruling the weak and vicious fire people, Flame Princess tells Finn they are no longer "going out"; however, Flame Princess adds that she and Finn can still be friends. It is unknown where her standing on Princess Bubblegum is, or how she intends to proceed with her relationship with her father, but Flame Princess seems to be calm and at peace with herself while figuring out who she really is in her heart.

As the days in the Fire Kingdom pass, an admirer of Flame Princess, who planned to help the Flame King escape in order to get her hand in marriage, broke into the kingdom and brainwashed the citizens, eliciting them to free the imprisoned king and turn against the princess. As Flame Princess was about to overpower him, she discovered the betrayal of her handmaiden, who had secretly poisoned her to impede her ability to fight and weakened her powers in order to help Flame King and Don John with her coup. Cinnamon Bun, unaffected by the spell Don John had cast, charged in and managed to help her escape. Flame Princess then came to a conclusion to seek help from Finn and explained specifically to him that they are not getting back together. Unfortunately, her explanation was to no avail when Finn impulsively charged into the Fire Kingdom in an attempt to win over the princess' affections, resulting in their imprisonment. Outraged, the princess turned both of her admirers down and told them that she did not have any feelings for them. This caused Don John to feel cheated and fought Flame King as the two prisoners made their escape with Cinnamon Bun, who managed to defeat the guards and steal the key. During his skirmish with the brainwashed citizens, he receives an attack and became fully baked before Don John's spell went off after his defeat during his battle with the Flame King.

After becoming fully baked, Cinnamon Bun was able to persuade the citizens to seize the king and help Flame Princess reclaim her throne by locking up the two threats in her lantern, as well as making a speech about her great leadership. Realizing that Cinnamon Bun is a trusty and competent champion and knight, she accepts his offer and hold his hand, and walks to the throne as her citizens cheer in approval of their relationship.

Following the events in which she reclaims the throne, Flame Princess spends most of her time traveling with Cinnamon Bun by her side, such as attending Princess Day and even during her free time when listening to the radio to Jake's story about "Mr. Bunny".

In "The Cooler", the Fire Kingdom's core is cooling down, causing the citizens' flames to reduce. As Flame Princess discusses what should be done about this with her family, her brother insists on attacking the Candy Kingdom to use the sugar to strengthen the fires. As Flame Princess informs him that she had already contacted Princess Bubblegum, the room begins cooling down and Cinnamon Bun helps the princess escape before she is hit with a blast of cool air. She goes to meet with Bubblegum, who tells Flame Princess to call her Bonnibel and asks what her first name, which Flame Princess refuses to answer. Bubblegum then picks up strong energy levels on her radar. She finds that they are behind a pair of large sealed doors and asks Flame Princess what is hidden in there. Flame Princess says that only members of the royal Fire Kingdom family are allowed in there, but Bubblegum convinces her to show her if she wants to save her kingdom. Reluctantly, Flame Princess opens the doors and presents the Sleeping Fire Giants, the Fire Kingdom's ancient guardians. As Flame Princess tells Bubblegum about being able to build a new Fire Kingdom with them and sings A Kingdom from a Spark while Bubblegum secretly steals the temperature control units from the Fire Giants. Flame Princess notices that she does this from one of them and becomes angry, but Bubblegum lies and says that it only fell out and she was placing it back in. However, her bag rips as she tries to move away and reveals the other temperature control units, causing Flame Princess to discover that her false ally's intentions were to disarm the giants, which led to an all-out fight that caused Flame Princess to accidentally destroy all but one of her Fire Giants. Bubblegum promised to leave her the final one, hoping she would change her opinion of her. She is shown later on one of PB's camera screens, where her brother complains about not starting war which Phoebe responds with a pat on the shoulder.

In "The Dark Cloud", she and Cinnamon Bun come to the assistance of Finn, Jake, Princess Bubblegum, and the Candy Kingdom in combating the Dark Cloud created by the Vampire King's extracted vampire essence, by using one of the Fire Kingdom's volcanos to fire a blast of lava at the vampire cloud however it fails to stop it and instead injures several Candy People who where fighting the vampire cloud.

In "Bun Bun," she greets Finn's delivery of Bun Bun to Fire Kingdom and asks him to stay for a chat. Over lunch, Finn admits he finally understands why it was wrong to manipulate Flame Princess to fight Ice King, and she is impressed by his maturity. They have some fun bonding over charades and Flame Princess' freestyle rapping skills, reestablishing their friendship. When Cinnamon Bun reveals Flame King has escaped and is now hanging out in a cave with some chipmunks, Flame Princess decides to let him stay there, recalling that animals bring out his more gentle side, and this experience could help him change for the better.

In "Elemental", Patience St. Pim orders Ice King to capture her along with Slime Princess and Princess Bubblegum. While playing a game of croquet with Cinnamon Bun, Ice King appears and splashes her with a glass of water, in which she retaliates angrily, but she is then frozen first with ice powers. Due to being wet, she is weak and couldn't escape, until Patience St. Pim tripped on her boat which broke, the sail (a wooden pole) bounces and breaks her ice bounds, she grabs the wooden pole, burns it, thus igniting her weakened flames. She frees the others including Finn and Jake then finally escapes with the others, leaving Patience St. Pim furious.

In the mini-series Elements, it is revealed she has turned into a Dragon and her fire powers can become blue. In addition she could turn others into fire elemental people. This causes them and herself to act extremely violent and is even more powerful than she was before. She however, was unable to remember anything from her life while in her elemental form. In "Hero Heart", she lost her element ablities because Princess Bubblegum turned her into a candy elemental person. In "Skyhooks II" she (along with the entire population of Ooo) were turned back to normal and were freed from the elementals.

Characteristics
Like all other inhabitants of the Fire Kingdom, Flame Princess is covered with fire, the very flames emitted from her body being extensions of herself that intensify when she becomes emotionally excited. According to Princess Bubblegum, Flame Princess' emotions are directly linked to her combustion levels, which explains her aggressiveness. When she is exposed to extreme romance, her elemental matrix will become unstable, and she would burn through the Earth's crust and set off a series of reactions, causing a meltdown that would burn up the planet from the inside. This reaction was started when Finn kissed her in "Burning Low," but the crisis was averted. Flame Princess eats coal and burns things to keep sustain herself. She was also the current incarnation of the Fire Elemental

Personality
Flame Princess has a short temper and volatile personality; she usually has a calm demeanor, though with rather frequent tendencies to sudden and violent mood swings. She is described as "passionate" by Finn, "evil" by the Flame King, and "intense" by Pendleton Ward. Flame Princess also has a sense of humor as even though Jake, who is controlling Finn, embarrassed him in front of her less-evil family by making him dance his Baby Finn song, she didn't get upset when she figures out the bet, instead she thinks it's pretty hardcore of Jake to do that and then wishes Finn good luck.

Since she was locked up when she was only an infant, Flame Princess is not educated properly and does not know much about the world beyond the Fire Kingdom. This is shown in "Hot to the Touch," where she was viewed to be examining flowers and was a bit surprised when she accidentally sets them on fire. She also did not know the definitions of sneaking or eating, though as she had served her family dinner in "Jake Suit," she seems to have improved on her knowledge regarding he outside world.

After Flame King started harassing her by calling her evil, Flame Princess began to question herself, and doubted whether or not she was in fact evil. However, after some time and a dungeon adventure to help her sort out her thoughts, Flame Princess concludes that, while she is a lover of destruction, she only enjoys destroying bad guys. Since she does not want to be influenced by evil people, she started spending time with her less-evil family members and was also upset when Cinnamon Bun told her that Bubblegum was evil in "Earth & Water."

After the events of "Frost & Fire," Flame Princess becomes more aware of trusting people and getting into relationships. She seems to have become more serious and dislikes how people "hide" facts from her. She wonders if "everybody is hiding something" and wants people to be completely honest so that she can get to know them better and as well not getting herself tricked. Wanting everybody to be trustworthy, Flame Princess enacted a rule in the Fire Kingdom to be completely honest after she overthrows her father and became the new ruler, no longer wanting to be fooled again.

She seems to be a benevolent ruler, seeing as how she helps her citizens with their problems and tries to make them happy once she became the monarch of the Fire Kingdom.

Physical Appearance


Flame Princess has long orange-red hair about waist-length that is like fire and as such flows above her head. She has black eyes that sparkle white and yellow in the light of her fire. Her arms are also portrayed as thicker than the majority of characters. Her skin is yellow-orange and she usually wears a orange-red dress under a light orange surcoat with hot pink trimming. At first, she does not wear shoes, though her dress usually hides her feet from view. She has two diamond-shaped, red gems; one on her forehead and the other on the front of her dress. The red gem on her dress is shown to be a part of her dress and not her exemplified when Flame Princess had a different outfit on in "Ignition Point."

When her flames are doused, her skin changes to a pinkish-gray hue, and her hair falls down her back and becomes a dull shade of maroon. Once in dry conditions, she returns to her normal appearance quickly. She turns into a similar appearance when she was poisoned in "The Red Throne."

She has many different enraged and battling forms, most of which have red eyes.

Costumes and Disguises
Flame Princess is normally seen wearing dresses, in all different shades of red and orange with a gem on some of her outfits and her hair is seen up most of the time.
 * In "Ignition Point," she wears a raspberry tank top with red matching pants under a clear layer, a pair of red shoes, and her hair in side-buns with a back ponytail.
 * In "Vault of Bones," she wears a light orange and raspberry strapless dress with fire at the end. Her hair was worn down and shorter with a curl on top.
 * In "Earth & Water," she wears a casual white dress with a peach-colored, short-sleeved surcoat, a hot pink sash and a pair of red boots that are about knee-length. Her hair was worn down and is slightly longer. As a baby, she is shorter in both physical and hair length and wears a raspberry t-shirt with a rock diaper. At the end of the episode, she wears a dark brown, full body suit armor with a skirt, copper sash, red trimming, knee caps, and Flame King's crown as her ruler outfit. Her hair is styled in a ponytail similar to the one she wear in "Ignition Point." She is also seen wearing this outfit in "The Red Throne" and "Princess Day".
 * In "The Red Throne," she wears her ruler outfit over a white-pink dress. Her skin turns dimmer and her hair falls down to her back, similar to when she gets wet. At the end of the episode, she is seen in her ruler outfit again, but with her hair worn down.
 * In "Jake The Brick," she is seen wearing an orange dress with hot pink collar and a red sash as her day dress.
 * In "The Cooler," she wears a light orange surcoat with hot pink trimmings, molten rocks on her shoulders, orange-red pants and red boots. She has the same hairstyle as she had when wearing her ruler outfit.
 * In "The Mountain," she wears a light orange crop top with a hood, orange-red pants and dark red shoes.
 * In "Bun Bun," she wears a white short-sleeve crop top, orange jogging pants, tied hair. She walks barefooted.
 * In "Skyhooks II," after she was freed of Patience's mega-spell, she wears an yellow-orange, ground-length dress with a v-neck collar, and the sleeves of which reaching past the elbows. The dress itself also has red-orange stripes going down the sides of the skirt, as well as the waistband, and collar. Her two gems are also missing in this form.

Relationships

 * -|Family=

Flame King
Her father, the Flame King, understands his own daughter as "evil," even having said so during "Incendium" in introducing her to "Finn" (Jake molding part of his body into a Finn-shape) when they first meet. In "Ignition Point" Flame Princess admits to hating that her father locked her away in the lantern for all these years and thus refuses to go back to Fire Kingdom after she finally leaves it behind when meeting Finn.

However, Flame King's concept of his daughter being evil is merely a factor of all Fire Kingdom citizens being evil and traitorous to one another, with him believing her like others yet with physical instability that would cause harm to anyone around her. He slightly could believe his daughter could gain a "good" alignment if she hung around people like Finn, but he does not know if it could work due to Flame Princess's fiery nature.

He later attempts to send subliminal messages to her while she sleeps by saying "evil," but it quickly stops when Flame Princess wakes up and sees this, leaving her shocked. He does so again at the start of "Vault of Bones" but stops upon realizing that she is not alone, causing Finn to look for a way to counteract his influence.

In "Earth & Water," when Flame Princess was born, Flame King feared she would become so powerful that she would overthrow him. So he had one of his servants to take her to the woods for her to perish. However, the servant took pity on her and gave her to a woodsman, but she wandered around and proceeded to burn the woodsman house and the surrounding forest. She was found by Princess Bubblegum, who brought her back to her father, where the Princess demanded he control his daughter. So, he locked her in a oil lamp-like cage. When Flame Princess discovered this, she and Cinnamon Bun went to the Fire Kingdom, overthrew her father, and locked him in the same cage she was once in.

Siblings
Flame Princess has two younger brothers (only one of whom has been named) and one older brother, Flint, who serves in the military.

Extended family
Flame Princess has two cousins, Furnius and Torcho, who hate her father because he killed their father in order to take over the Fire Kingdom.

She also has an aunt and uncle who are very judgmental.
 * -|Friends=

Jake
Jake enters the Fire Kingdom to court Flame Princess on behalf of Finn, who is feeling heartbroken after having been pushed away by his previous love interest, Princess Bubblegum.

Jake sings her a song and accidentally kills her father's jester by spilling water on him, both of which she apparently enjoyed; however, she does not react much when "Prince Finn" kills Jake.

In "Burning Low," Jake does not interact much with Flame Princess but they seem to be friends and Jake has approved of her; he even helps Finn in courting her with a poem.

In "Ignition Point," they interact much more and they seem to be comfortable with each other; it was Jake who suggested going to the Fire Kingdom to get her the scented candles.

Jake seems glad to see Finn happy with Flame Princess, as he was the one to seek her after Finn was rejected by Princess Bubblegum. Jake also keeps his distance when Finn and Flame Princess are together, as shown in "Burning Low" when Finn asks Jake if he wants to check out Flame Princess's new house and he politely refuses and tells them to go ahead. Also in "Vault of Bones," while Flame Princess and Finn are playing cards, Jake offers them chamomile tea to show his support of their relationship.

In "Jake Suit," Jake embarrassed Finn in front of Flame Princess and her less-evil family members by making him semi-naked and singing the Baby Finn Song as he thought that would make him win. However, he was unsuccessful because Flame Princess spotted him inside Finn's mouth while talking to him (Finn). She thinks that it was pretty hardcore of Jake for doing that to Finn.

Cinnamon Bun
In "Earth & Water," when Flame Princess submitted herself to experiments by Princess Bubblegum to control her emotions, Princess Bubblegum had to leave to help Finn and Jake so she had no choice but to put Cinnamon Bun in charge of the experiment. However, he brought Flame Princess to his house to talk. Liking his honesty and after recalling that it was Princess Bubblegum who had her father put her in the cage where she spent her childhood, they both went to the Fire Kingdom and overthrew the Flame King and enacted a policy where lies were not allowed.

In "The Red Throne," Cinnamon Bun seems to and act as Flame Princess' closest friend and helper. She had also shown great concern for him when he got hit by a fire during a fight with the Fire Kingdom citizens, apparently knowing how he feels. After Cinnamon Bun was "fully baked," he admits his love for Flame Princess and pledges to be always by her side as her "knight and champion." She accepts his offer and hold his hand. It has been confirmed in a tweet by Cartoon Network's official Twitter that the two had not been dating and by the writers as well.
 * -|Love interest=

Finn
Flame Princess does not actually meet Finn in person until the very end of "Incendium." After she is doused with liquid pyrotechnics, she unconsciously falls off the roof of the Tree Fort. Finn catches her as she is falling and brings her inside. She regains consciousness and angrily asks Finn why he does not like her; Finn replies that he does like her, which causes her to blush in surprise. Confused by Finn's apparent fickleness, she slaps him and warns him never to mess with her again—unaware that Jake was the original "Prince Finn."

In "Hot to the Touch," Finn wanders into the woods to search for the Princess, after asking Jake about her and saying he really likes her. When Finn finds Flame Princess he watches her from a bush at first, calling her innocent like "the steam off a puppy's nose searching for ham in the snow" and "a cute little flower." She touches a pool of water, hurting herself, and Finn jumps out from the bush to her aid. He then tells her that he was worried about her and thinks that she is beautiful. This causes her to glow, causing some fire to spread around Finn and herself. Finn puts out the fires in a panic which causes her pain, causing Flame Princess to believe that Finn is intentionally hurting her. She leaves in a huff without allowing Finn a chance to explain, not listening to his claims that he was not trying to hurt her.

After a brief chase, she concludes Finn is trying to impede her, so she decides to turn the Grass Lands into her own fire kingdom. She begins by heading for Goblin Kingdom to set it and its citizens on fire. Finn and Jake attempt to stop her with Robo suits made by Neptr, but Finn only attempts to talk her out of it rather than put out her fires. When Finn realizes he cannot make her understand his feelings, he tears a hole in his robo suit and cries wishing he could "just like a girl." One of his tears falls onto the flames as she is walking away from him, causing her to turn around and witness him crying. She becomes convinced that he is a "Water Elemental," saying that all he does is cry and cry all the time. She comes to the conclusion that they are opposite elementals and that even if they like each other, they would hurt each other. However, Finn suggests that they try to make it work and that he can take it. She seems happy that he would want to defy nature for her, and both lean in to hug one another. As they hug, Finn gets burned and pushes her away. She looks at him appearing unsure, and then leaves saying, "Bye, Finn."

In "Burning Low," she and Finn are dating. Finn helps her build a new house in the Grass Lands out of wood scraps, and she tells him that she loves it. Her flames trail over to Finn's foot and he is surprised to realize that it does not hurt as bad as it used to; though, once the flames crawl up his leg he screams in pain and jumps into the water. Finn and Flame Princess hug once he is out of the water, although Finn has to wear many layers of tinfoil to protect himself. While walking home, Finn asks Jake for advice about dating, to which Jake explains the concept of "tiers" and tells Finn that he should move on to Tier 2, which is kissing. Later in the episode, Finn goes on a date with Flame Princess off-screen and tells Jake that he was not able to kiss her yet (though he got 5 hugs), so he is still on Tier 1. Jake advises Finn to write a poem for Flame Princess in order to move things along. Finn tries to think about Flame Princess's qualities, and he ends up going outside and watching the sunrise, which gives him inspiration to write. He takes the finished poem over to Flame Princess's new house and reads it to her. After he is done they stare into each others' eyes and kiss. The kiss triggers a reaction and causes her to burn so hot that she melts through the ground, as Princess Bubblegum stated. As she is falling, Finn grabs Jake's arm, ties it around himself and jumps down after her. Flame Princess's reaction is halted by lack of oxygen, and when Finn catches up to her she is extinguished and passed out. Though nearly out of oxygen himself, Finn picks her up and tells that he needs her to be okay. He then gives her, which causes her to re-ignite (though Finn passes out from lack of oxygen). Jake pulls them out of the hole and both of them are all right (parts of Finn's face are burned from the kiss). Finn asks Flame Princess if she is okay after what had happened. Finn picks up a rock and kisses it, then hands it to Flame Princess who kisses it as well.

In "King Worm," Flame Princess is feeding Finn (whom she calls "honey") soup; first lovingly, then angrily when he hesitates (he was confused, having been with Princess Bubblegum as her king and husband seconds earlier). However, Finn soon discovers that he is in a dream and she is not the real Flame Princess.

In "Ignition Point," Finn and Jake travel to the Fire Kingdom to retrieve Flame Princess's scented candles. While there, Finn finds out that Flame Princess is evil, but he seems pleased to know that she could possibly be turned to good.

In "Reign of Gunters," Finn takes the advice of a dating book called Mind Games and tries to act more mysterious.

In "Vault of Bones," she goes to the Vault of Bones with Finn to prove to herself that she is good. He teaches her properly how to dungeon crawl, but she finds his methods boring (due to her impatient and destructive personality) and tells him that she is not having fun. After Finn allows her to do things her own way, she proceeds to burn everything down with her elemental powers. When a Giant Goo Skull captures Finn, she rescues him by intimidating it and calls him her boyfriend for the first time. At first, Finn thought he was going to be burned alive because of how Flame Princess approached the Goo Skull, but after he is rescued, Flame Princess says she would never hurt her boyfriend. At the end of the episode, Flame Princess thanks Finn for taking her to the dungeon and suggests that they go to another dungeon sometime.

In "Jake Suit," she invites Finn to her house to meet her less-evil family members. She totally does not even mind that he makes a fool of himself once she finds out it was for a bet with Jake. She believes that Finn will win and cheers him on, giving him the support he needs to survive the final stretch of Jake's gauntlet.

In "Frost & Fire," Finn and Flame Princess are interrupted by Ice King in the middle of a picnic. After Flame Princess beats up Ice King for insulting her, Finn starts to have weird dreams with the Cosmic Owl in it, but keeps waking up before he can finish the dream. Finn tries to get Flame Princess and Ice King fight by writing insulting messages about them and claiming the other sent it. This, however, leads to Finn attempting to apologize and to continue their relationship, but to no avail as Flame Princess leaves saying "...I need some time alone."

In "Too Old," it is revealed the couple had broken up, and so Finn makes one last attempt at Princess Bubblegum. It fails as usual, and he tells Jake he has to "patch things up with Flame Princess," so it is unknown if they get back together or not, as Jake ominously states Flame Princess could have already replaced Finn with a new boyfriend.

In "Earth & Water," Flame Princess has troubles controlling her emotions again after her breakup with Finn and ponders whether she wants to be with him again. She later befriends Cinnamon Bun when Princess Bubblegum leaves her unattended in the middle of a test and tells him that sometimes friends are "hard to understand" and that they are "just playing mind games." This may be due to Finn keeping all the ladies in confusion after reading the book Mind Games in "Reign of Gunters." Later in the episode, Flame Princess overthrows Flame King and became the new ruler. When Finn tries to apologize to her, she accepts his apology. He asks her if they are still going out. She says no but they can still be friends and that he can come by anytime as long as he is completely honest with her.

In "The Red Throne," after being secretly poisoned by her treacherous hand maiden and escaping Flame Lord, Flame Princess seeks help from Finn in order to save the Fire Kingdom. Despite apprising Finn specifically that they are not getting back together and that they are only meeting so that he can help her reclaim her kingdom, Finn tried to impress the princess with his improved swordsmanship and showed-off impulsively by charging into the Fire Kingdom, which annoyed Flame Princess. In the dungeon, Finn revealed that he thinks that Flame Princess still has feelings for him, to which she protests.

Finn continues to admit to others his love for her in "Love Games" and "The Pit." Despite her rejection, she does, however, still want to be friends even after his betrayal in "Frost & Fire." In "Breezy", it is revealed by Dr. Princess that Finn no longer talks to Flame Princess, indicating he no longer has feelings for her and instead harbors contempt (although in "The Mountain" when he sees her, she "kinda messed (Finn) up"), possibly since he thinks Flame Princess and Cinnamon Bun are dating.

It is likely that Finn continues to harbor genuine romantic affection for Flame Princess, as seen in The Comet. When the Purple Comet offers Finn a new mode of existence, she explains the crisis caused by the weight of this decision. She goes on to mention the various aspects of his human life he would be free from, the first is love, which is signified with a modern appearance of Flame Princess. This isn't to say that his feelings might not have changed at all, or that they are reciprocated by Flame Princess, but they likely still exist despite the conflict caused in himself by her rejection.

In "Bun Bun" Finn delivers Bun Bun to the Fire Kingdom. Flame Princess was excited to see him and invited him in for lunch. Finn apologized more sincerley this time saying "I said I was sorry but I didn't fully understand what I had done wrong." Flame Princess was happy to hear that and said that he's grown up a lot. After this the two have fun as friends and are now seen casually together without any drama.

In the series "Happy Warrior" Finn was concerned that the supposedly dragon (in fact, the image of the Fire Princess) had eaten it, but after a while, succumbing to anger, he himself became a Fire Elemental. Lumpy Space Princess thinks that they have a chance to come together again.

Princess Bubblegum
Though not interacting with each other, Princess Bubblegum reveals to Jake in "Burning Low" that Flame Princess is unaware that she is the one who had the Flame King lock up his daughter in the lantern due to her physical instability. Princess Bubblegum knows, in great detail, about Flame Princess's elemental matrix, what "extreme romance" would do to it, and how to stop the resulting reaction.

In "All the Little People," Princess Bubblegum and Flame Princess, however, in toys forms, had their first interaction with each other by fighting over mini Finn. This is not likely to happen between them in reality as Princess Bubblegum does not hold any feelings for Finn, as well as Flame Princess, after their break-up.

In "Earth & Water," Flame Princess was outraged to find Princess Bubblegum spying on her but agrees to help her by creating a scientific model that describes her complete elemental matrix, so she can isolate and suppress her violent feelings. When asked about her relationship with Bubblegum, she said that it was unclear whether they had formed a friendship. After Cinnamon Bun asks Flame Princess why Princess Bubblegum put her into "baby jail," saying that this was "a weird friend thing," she finally realizes that it was Princess Bubblegum's idea to lock her in a lantern while she was a baby.

It is unknown if she holds any actual bitterness towards Princess Bubblegum towards this. In "The Red Throne," she states that she does not trust her, but out of an unknown reason.

In "The Cooler," Princess Bubblegum faked a disaster in the Fire Kingdom by hiring Ice King to freeze the core of the Fire Kingdom, weakening the life force of the flame citizens. Flame Princess, who was unaware that Princess Bubblegum was the threat to the kingdom, seeks help from her but disregards Bubblegum's attempts to act as her friend (in order to gain Flame Princess' trust) and apprised her furiously that she had only asked her help to save her kingdom, not because she trusts her. As Bubblegum's plan works out, she persuaded Flame Princess to let her enter the room which contains the ancient relics of the Fire Kingdom and steals the thermic control units of the Sleeping Fire Giants while Flame Princess was singing A Kingdom from a Spark. When caught stealing the units, Princess Bubblegum immediately denied it and lied to her that one of the units had fallen out and that she was just putting it back. Unfortunately for her, she accidentally ripped her bag, where the stolen units were placed, causing Flame Princess to become furious and thus starting a fight between the princesses. Bubblegum then decides to use Flame Princess' attacks to destroy the Giants and taunts her by calling her a "ding-dong" who does not deserve her trust. However, Flame Princess managed to catch Bubblegum off-guard and defeated her. She pointed out that Princess Bubblegum had been exerting authority she does not possess and making decisions for its citizens that is not hers to make and threatened to kill Bubblegum after her defeat. Princess Bubblegum then counter-attacks by sending a sphere that releases electricity into the smoke from the damaged statues, creating rain and thus weakening Flame Princess, preventing her from killing her. While trying to recover from the battle, Princess Bubblegum decided to come clean and explained that she was trying to get near Flame Princess' weapons stockpile to protect her kingdom, as well as revealing that she had put a video camera to spy on Flame Princess. Flame Princess was aggravated to hear this and accused Bubblegum of being a bad person. Princess Bubblegum regrets her actions and tells her that she is not an all bad person and tried to prove it by leaving one of the Fire Kingdom's Fire Golems active. The two amend and Flame Princess openly answers her question about what her first name was; Phoebe. Princess Bubblegum then calls Ice King off from freezing the core, reverting the Fire Kingdom back to its normal state.

Ice King
Before there had been any direct contact between Flame Princess and the Ice King, he seems to have known her because he mentions Flame Princess in "I Remember You," probably from hearing about her from Finn and Jake. Flame Princess is one of the princesses that the Ice King calls "okay."

The two first interact in "Frost & Fire," where Ice King insults her for hugging a log, causing Flame Princess to throw a beatdown. She punches him in the stomach, slaps him several times, and kicks him back into the Ice Kingdom. Later in the episode, Finn forges a letter to make the two fight again. Enraged, Flame Princess defeats him in the final battle and destroys the Ice Kingdom. She finally stops when Finn admits that he wrote the letter, knowing that the Ice King is innocent. It is unknown whether how Flame Princess felt for the Ice King.

Flame Lord
Flame Princess seems to have known Don John before the events of "The Red Throne," calling out his name when he breaks in. He helps Flame King to reclaim his throne and secretly poisons her, causing her to lose some of her powers. She and Finn are later thrown into the Fire Kingdom dungeon, after Finn breaks into the kingdom and pulls Flame Princess in. There, Don John tells her that she will be his and reveals that he wants to marry her. Flame Princess eventually turns him down and tells him that she will never marry him because she does not have feelings for him, and that forcing her to marry him is gross. After Cinnamon Bun frees them, and the Fire Kingdom citizens start to beat up Flame King, Flame Princess punches Don John in the way she did to Ice King, knocking him out. She throws him into the lantern and locks him up with Flame King.

Powers and Abilities

 * Tumblr_n17dn1xy831t5ct7wo1_500.gif the Fire Elemental, Flame Princess is able to conjure up flames at will, transform other citizens of the Fire Kingdom into Flambits, transform into a larger, more dangerous form composed purely of fire, hurl fireballs that can vary in size, and separate her body into distinctly separate groups of flames. She appears to be able to consciously extinguish fire she has created; she does this when she notices Finn crying in "Hot to the Touch".
 * Tumblr_n17dn1xy831t5ct7wo9_r1_500.gif can unleash small blasts of fire by using her fingers and throw disks of fire as seen in "Ignition Point."
 * Tumblr_mqrzf70Ioo1snq21po1_400.gif can emit a continuous flamethrower from her hands, but the length of time she can sustain it is debatable.
 * Tumblr_n17dn1xy831t5ct7wo5_r1_500.gif can also make a Flame Sword, in which she concentrates an isolated flame, extending from her arm, that is intense enough to glow blue. Immediately following that, she used a Dash ability that sent massive pieces of shrapnel from a steel door (which she had just cleaved into four pieces) in all directions, as seen in "Vault of Bones."
 * FPBustDoor.gif can sense that a tree is not made of wood by using her Heat Sense.
 * Tumblr_n17dn1xy831t5ct7wo7_r1_500.gif has full manipulation of her body, morphing it into asymmetrical flames at will. Her father also has this ability, and it may be the norm among fire elementals this is shown when she first steps into her new house.
 * She can shoot beams of fire from the center of the gem on her forehead, as shown in "Frost & Fire" and 'The Cooler." She is also able melt the icicles that the Ice King creates without touching it when they fly towards her.
 * She has the ability to float and move very quickly, both of which leave a trail of flames.
 * She is also a natural at rapping.

Weaknesses

 * S5e30 FP weakened.png weakness is water, shown after unintentionally setting off some of Princess Bubblegum's liquid pyrotechnics and when she puts her hand into a pond. The liquid pyrotechnics caused her to become unconscious, and touching the water in the pool caused her pain.
 * The fires that Flame Princess makes are a part of her, and stomping on or dousing the fire hurts her. However, after her second appearance, she was shown to be able to handle a part of her flames being doused, as shown in "Burning Low" and "Vault of Bones," where Finn puts out her fire in both episodes and she did not react or show any signs of pain.
 * She also has a partial weakness in ice, shown when Ice King throws his groceries (which were frozen) at her, when one of the Snow Monsters hugs her and when the Ice King, while fighting a furious Flame Princess gave her a noogie with his ice controlled tower with hands made out of snow, all three which hurt or douse her.
 * In "The Red Throne," Flame Princess loses some of her abilities when she is poisoned by her handmaiden, who is acting on behalf of Flame King. This causes her flame-hair to fall down, and Finn notes she is relatively cool to the touch. Flame King notes at the end of the episode that she is even weaker than before due to the poisoning, but it is unclear if its effects are temporary or long-term. In the episode, Flame Princess does not seem to have most of her usual flame-blasting or shifting abilities. This also proves that besides water, Flame Princess can also be weakened with poisons.
 * In "The Cooler," it is revealed that when the magma in the Fire Kingdom's core has cooled down, it can weaken the life force of the Flame People by producing cool air pockets, to which the people loses heat to and contracts, causing them to reduce in sizes. Flame Princess, being one of the victims, was shown to have her skin to be much dimmer but this, however, did not cause her flame-hair to fall down. According to Princess Bubblegum, this had caused her to lose most of her powers. Despite the effect, Flame Princess was shown to have still her usual flame-blasting powers during her fight with Bubblegum, turning into larger forms, shooting fireballs from her gem, creating large fireballs and two fire blades with her hands. By the end of the episode, she was shown to had reverted back to her normal state.

Trivia

 * Pendleton Ward and the show's cast first introduced Flame Princess at Comic-Con 2011.
 * Natasha Allegri has drawn Flame Prince, a gender-swapped version of Flame Princess, in her artwork. He has appeared in the mini comic that started in early January of 2013 and as a minor character in "The Prince Who Wanted Everything" and "Five Short Tables."
 * Flame Princess is the only known princess to have invaded another kingdom by herself.
 * In the original storyboard for "Hot to the Touch," Flame Princess was supposed to kiss Finn; however, the idea was dropped and reused for "Burning Low."
 * When Flame Princess transforms into her larger form, her face resembles that of her father, the Flame King.
 * She is different than the other flame people curiously, being that she can be completely wet and yet only be rendered unconscious at the most, instead of killed. This is possibly due to the fact that, as royalty, she likely has abilities beyond typical flame people.
 * She is one of the few flame people with a humanoid shaped body.
 * Although it appears as if Flame Princess' hair is made of fire, it does not disappear when she is extinguished or wet; instead it falls down to her back and behaves like normal hair. It most likely transforms, or the hair is more of a fuel for the fire.
 * When in a doused state, her gems appear to turn a maroon color.
 * She refers to Finn as her boyfriend in "Vault of Bones" and Finn refers to Flame Princess as his girlfriend in "Puhoy."
 * In "Puhoy," Finn is briefly concerned that their relationship is over after Flame Princess did not get a joke he made, and ventures into a Pillow World where he lives through a lifetime with a pillow wife and pillow children. When he dies of old age in this world and "returns" to Ooo, he immediately gets a phone call from Flame Princess telling him she now gets the joke, and promptly forgets about his "dream" of the Pillow World.
 * She is one of the two princesses who have ran away from home and lived out in the grasslands because they hated their parents and how they treated them. The other one is Lumpy Space Princess. She is also one of the two princesses to have another emblem aside from a crown to represent her royalty as a princess. The other one is also Lumpy Space Princess.
 * However out of the two, only Lumpy Space Princess has reconciled with her parents.
 * It may also noted that she is the third member of royalty that hated their father, along with Marceline and Lumpy Space Princess; however, Lumpy Space Princess's hate stretches to both her parents.
 * Although she overthrew her father and became the new ruler (making her obtain a crown) and started living in the Fire Kingdom again, she was still considered one of the two princesses as she does not have a crown when she was only a princess and she ran away from home and lived out in the grasslands at the same time.
 * In the episode "Hot to the Touch," it is proven that whenever Flame Princess's fires are put out, she gets hurt. However, in the episode "Vault of Bones" Finn threw a torch in the water that was lit with Flame Princess's fire and she did not show any pain. Also in the episode "Burning Low" Finn jumped in the water putting out fire that was on his foot that was caused by Flame Princess and she did not seem hurt at all.
 * In "Earth & Water" she overthrows her father and becomes the new Flame King.
 * In the episode "The Pit," Finn mentions that he still loves her, even though she rejected him in "Earth & Water."
 * Unlike the others, in most video games, she is seen in her outfit in "Vault of Bones" instead of her main outfit.
 * Her personality is similar to that of Fryno from Skylanders: Swap Force.
 * Coincidentally, both control the element of fire.
 * Flame Princess' name, Phoebe, means 'bright and shing one', which is apt as her body generates light along with heat.
