As shown in "Memories of Boom Boom Mountain," Finn appears to have been abandoned in the woods during infancy. He reveals that he made "boom boom" (Finn's word for defecation, also known as stools) on a large leaf, then fell on it, and lay there crying until Joshua and Margaret (Jake's parents) rescued him from the wilderness. They raised him alongside Jake, who, along with Jermaine, became Finn's adopted brother. In "Memory of a Memory," a baby Finn is seen singing a song in the bathroom of what appears to be Joshua and Margaret's house. In "Henchman," when Finn is asked about his parents, he says Jake told him that he came from a cabbage as a jest. In "Susan Strong," Finn states that he knows nothing of his human parents or any other humans.
Status as the last human
Finn was for a long time, the only confirmed human in the Land of Ooo. In the episode "Her Parents," Lady Rainicorn's dad says he thought humans had been extinct. This lends new significance to his title "Finn the Human," as his humanity may be unique in Ooo.
Up until "Susan Strong," Finn believes he has never met another human and becomes morose and "soul-searchy" when he thinks about it. In the same episode, Finn encounters Susan Strong. Even though the other members of Susan's tribe of Hyoomans are revealed to be mutants, Susan's identity as a human or mutant is left ambiguous. In "Beautopia," it may be true that Susan is also a human, but it was not confirmed. The businessmen may be humans, though with their minds damaged from their suspension in an iceberg, giving their tonal inflection and, to some extent, mental capabilities zombie-esque qualities.
Other "human" characters (such as Penny, Phil or the Old Man Henchman) have been confirmed by the show's creator, Pendleton Ward, to be mutants or humanoids. According to Pendelton Ward's FAQ page, even Finn is mutated in some way.
Fionna is also a human, although she is just a character in Ice King's fan fiction. Ice King was formerly a human, as shown in "Holly Jolly Secrets Part II." Mothering a half-demon, Marceline's mom was also human when she gave birth to Marcy, though her fate is unknown.
Moe, creator of BMO was also human but as he grew old, some of his functions were replaced by machines while only his skin and hair remains human. He is still now classified as a humanoid, since he is a human-like being that lives in the land of Ooo.
In "Billy's Bucket List," Finn is told by Billy (who was dead but speaking through a constellation in the sky) that his father is in fact still alive, though when shown, Finn's father appears to be frozen in some sort of gem, in what may be some sort of cryogenic sleep. However, it is still unknown whether Finn's mother is currently alive.
Appearance and equipment
Finn is a 15-year-old human. He is roughly five feet tall. He has several missing teeth because he bites trees and rocks among other things.
Although his eyes typically lack detail and appear as small black dots due to a minor mutation, they are shown to have color in "The Enchiridion!" when Finn is tried by the Dark Magician. His left eye is green while his right eye is blue, characteristic of the genetic condition heterochromia. However, as stated by lead character designer Andy Ristaino on Spring, "That was a special occasion. The heterochromatic effect was a byproduct of him being hypnotized by that guardian dude." Andy confirmed that Finn's eyes are blue.
In "Escape from the Citadel," Finn's right arm is actually torn off, and then coated by the blood of a Citadel Guardian, which grows a small flower. He later got his arm back in the episode, "Breezy."
Finn has blonde hair which is first seen in "To Cut a Woman's Hair," where Finn removes his hat, and long, golden locks of hair flows out. His hair has a glowing sheen and extended his body length, until he cuts it off and gives it to the Tree Witch. His hair slowly begins to regrow throughout several episodes, as shown in "Mortal Folly," "Heat Signature," "Apple Thief," "Beautopia," "No One Can Hear You," "Another Way," "Beyond this Earthly Realm," "Gotcha!," "You Made Me," "Who Would Win," "The Hard Easy," "The Lich," "Jake the Dog," and "All the Little People," In "Another Way," Finn's hair has grown to the point of nearly his shoulders, and later, in "Beyond this Earthly Realm," Finn's hair is shown to have grown past his shoulders. In "Gotcha!," Lumpy Space Princess sees an illusion of Finn with hair reaching his waist. Finn's hair is also seen in "You Made Me" when he defends Princess Bubblegum from Lemongrab's attack, which causes his hat to fly off. A few strands of his hair are seen coming out in "Who Would Win" after Finn repeatedly gets beaten by Jake and later throughout the episode. The hair makes an appearance in "The Hard Easy," having roughly the same length as in "Beyond this Earthly Realm." In "The Lich," Finn pulls off his hat, where it seems to be a bit longer than in its appearance in previous episodes. In the episode "Davey," Finn has shaves off almost all of his hair for the second time so he can disguise himself as 'Davey'. In "Little Dude," it starts to grow again. In "The Great Bird Man," Finn's hair seems to be growing longer again. In "A Glitch is a Glitch," his hair is the same length from when it was first shown. In "Puhoy," Finn, as an adult, grows facial hair. His hair can also be seen in "Jake Suit." In "Love Games," his hair appears to be the same length it was in "You Made Me." In "Dungeon Train," it appears a bit shorter than in "Love Games." His hair has also appeared in "Billy's Bucket List" and "Escape From the Citadel" looking about the same length as in "Beyond this Earthly Realm."
- Main article: Finn's hat
Finn wears a white hat with two "ears" sticking out on top. The hat is inspired by a character called Bueno, a bear that appears in comics made by Pendleton Ward, the creator of Adventure Time. Consequently, Finn's hat is bear themed; coincidentally the Hyoomans wear animal themed hats as well. This might be a hint that humans in the Land of Ooo wear animal hats to fit in the society. Finn's hat covers his entire head except for his face. He also wears a light-blue T-shirt (or as he would call it, baby blue "boy-style"), denim shorts, a green circular backpack, rolled-down white socks, and a pair of black shoes. In "Ocean of Fear," his footwear appears to be black booties with white cuffs. In "It Came from the Nightosphere," Finn has a small pocket sewn onto his shirt that he carries Jake in. It appears again in "Davey" where he uses it to hide Jake while Finn steals the keys from the guards as he breaks the former out of jail. When he is in the Ice Kingdom, he occasionally wears a yellow sweater, but currently wears his pink sweater made by Princess Bubblegum. During "In Your Footsteps," the Bear wears Finn's clothes, which suggests that Finn has multiple sets of the same outfit, along with multiple hats. However, in "Little Dude," when Finn's hat comes to life and is set free, Jake tells Finn, "Okay, let's go skin an evil bear," which may imply that Finn only has one hat, or only had one hat left.
Finn sleeps in red footie pajamas that appear in many episodes, but in the animated short, he sleeps in a red sleeping bag in his regular clothes. In the series, the sleeping bag is beige.
- Main article: Finn's swords
Although Finn has wielded a number of weapons, he originally favored a gold sword. In the episode "Mystery Train," Finn is shown using a new sword with a pink/silver blade and a red, twisted "root" handle. (Finn's original sword was destroyed by a black hole in "The Real You") Along with his new root sword, his green backpack has a new side strap that can hold the sword while Finn is walking. In the episode "Dad's Dungeon," Finn and Jake venture into Joshua's dungeon, which was built by Joshua to toughen Finn up. In the dungeon, Finn retrieves Jake's family sword, which replaces the root sword as his primary weapon. Finn's grass sword, as seen in "Blade of Grass," works as a retractable weapon that is attached to his right arm. He has since lost this sword along with most of his right arm. There are a number of other swords seen being used by Finn, but it seems that he had not kept them or interested on using them.

Personality and character traits
Although at times violent and aggressive, Finn is a brave and righteous hero. He has a very strong sense of responsibility and becomes upset when he is unable to help others. He seems to be somewhat overprotective of his friends; such as when Tree Trunks almost gets killed in the episode "Tree Trunks" and Jake in "The New Frontier." He is almost physically incapable of doing anything evil or unjust, and will struggle greatly against doing such things, as seen in several episodes such as "City of Thieves," "Mortal Recoil," "The Eyes," and "The Enchiridion!" Even though he acts like a normal boy, Finn acts like a gentleman when it comes to ladies. As revealed in "Davey," despite his heroic nature, he also takes a liking to a "normal life" without any recognition or praise for being a hero.
While he portrays himself as a rough and tough hero, Finn has a tender side that is capable of love and compassion, as shown by his boyhood crush on Princess Bubblegum and his brotherly relationship with Jake. However, Finn seems to hate romance movies and kissing as in "Go With Me," he actually vomits during a kissing scene in a movie. However, at the end of "Dream of Love," Finn is not disgusted by Tree Trunks and the Pig kissing. Finn's growth in accepting romance and physical love is also demonstrated when he willingly kisses Princess Bubblegum in "Too Young" and his latest ex-girlfriend, Flame Princess, in "Burning Low."
Finn's aspirations to be a great hero makes him somewhat of a moral sheriff in the Land of Ooo, as he is willing to help and protect any innocent person or creature. Finn appears to be somewhat simple-minded, seeing that he gets a lot of conflicting emotions when it is unclear whether something is good or evil (exemplified by his dealings with Marceline in the episode "Henchman"). He is shown to have high hopes of his father being a great hero in "Wake Up," and is visibly distraught and disappointed to discover that he was nothing more than a selfish criminal. This, coupled with the fact that Finn lost an arm and a sword because of his father's selfishness further pushes him to the point of wanting revenge on the man, as seen in "The Tower," when he attempts getting into space via a tower that he built using a telekinetic manifestation of an arm. Suffering from such a betrayal seemed to have an impact that will last on Finn, as in "James II," rather than help Princess Bubblegum or the Jameses in the matter, he simply sat behind with Jake and watched the chaos, even finding it amusing. This, coupled with his attempt at revenge for his arm in "The Tower" seem to hint that he has become less caring of people.
Many aspects of Finn's personality are shrouded in mystery. In the episode "Rainy Day Daydream," it is shown that Finn believes that "imagination is for turbonerds who can't handle how kick butt reality is" and that he finds real life to be fantastic. Finn then refuses to use his imagination until he has to reactivate Jake's "bombastic personality" in his imagination land, (which was just a basic gray and white empty plane hinting that Finn is not very imaginative). However, this is disputable when the gnomes harness the energy from Finn's imagination in the episode "Power Animal" despite it being inhabited with a few dainty creatures such as Bellamy Bug. The gnomes state that Finn's imagination is powerful enough to effect the real world (like Jake's but to a lower degree) and turn on Jake's imagination.
Finn can also be very stubborn; such as in "Memories of Boom Boom Mountain," "Wizard," "Dungeon," "Rainy Day Daydream," and especially in "Another Way." Finn can also be easily tricked, as in "The Eyes" when Jake convinces him that the giant hawks would take the horse to a land of sunshine and love stuff and take care of him. He can get overly angry and yell as in "Trouble in Lumpy Space" and "Tree Trunks," but immediately feels guilt and remorse and apologizes when he can. Finn prefers to do work without taking the easy way out as seen in "Business Time" and "The Real You."
Finn is shown to be a courageous warrior and a fearless thrill-seeker. He enjoys putting himself in the midst of danger simply because he enjoys a challenge. However, he is also shown to have several fears. In "Another Way" and "King Worm," he demonstrates a fear of clowns. Also in "King Worm" he shows a fear of Bubblegum calling him too young. In both "King Worm" and "Ocean of Fear," Finn has an unexplained phobia of the ocean, or thalassophobia, despite the fact that he can effortlessly come into contact with any other body of water. Other fears that Finn has are the Ghost Lady ("King Worm" and "The Creeps") and either the return of the Lich, or possibly just the Lich himself. Despite all this, Finn is a very kind and selfless person who is always putting the safety of others above his own. Jake also says that "he is a good kid with a kind heart." a trait which is true and shown by Finn throughout the whole series. However, Finn is shown to cause or get himself into trouble sometimes, but due to his kindness he's willing to either try to fix it or to apologize for what he did (ex.When he caused Flame Princess to get hurt by the Ice King.) Another trait that Finn has is empathy, this was caused by his past when he was a baby since no one (except Jake's parents Joshua and Margaret) helped him.
In "Billy's Bucket List," when Finn has to go into the ocean to fulfill Billy's wish, he is shown once again incapable of going into the ocean. Fear Feaster returns to throw insults at Finn's weaknesses, but is put aside when Finn hits himself with a plank and falls into the ocean, unconscious. After a few scenes of hallucinations in the ocean, Finn surfaces from the ocean, with the Fear Feaster with him. Finn's hand slaps his face (possibly the grass sword's doing) and convinces Finn to slice the Fear Feaster, who doubts the sword's powers. Once the Fear Feaster is cut, he explodes, thus erasing all of Finn's fears.
Finn can jump very high and is exceptionally strong and agile for a boy of his age. Despite his age and appearance, Finn seems to be quite strong and athletic; he can be seen wrestling full-grown Marauders, the large grass ogre Donny, and a general variety of monsters and creatures several times his size. Finn is also capable of lifting up Princess Bubblegum, as shown in "Mortal Recoil" when he picks her up and puts her in her bed, and capable of lifting up Marceline as seen in "Daddy's Little Monster." In addition, he is able to pick up a tree and hit Barb, a giant spider, in "Web Weirdos." In "Another Way," Finn is able to run around carrying a giant cyclops' eye. Lastly, in "Dad's Dungeon," when he stabs the Evil Monster in the eye, he is able to lift it up slightly off the ground and flip it into the pit. Being the size it is, the giant Evil Monster should have weighed at least several tons, thus showing Finn's strength. He also can make his arms and legs bend in inhuman ways, as during the Science Dance and when he uses "spaghetti limbs" (waving his arms and legs, which Jake can also do). In "The New Frontier," it is shown that Finn can make fire only with his hands. Finn is very tolerant to pain as shown in "No One Can Hear You" when the stag breaks his legs; he just says, "whatever." Also, in "The Lich," he is able to break the Enchiridion on his knee. He even tries to teach Jake how to tolerate pain in "Jake Suit," when he says, "just pretend like every bruise is a hickey from the universe." Finn seems to have impeccable balance, as he is able to balance himself on two wheels in his wheelchair in the episode "No One Can Hear You." However, he refers to it as "skills." One of Finn's weaknesses is short-cone monochromacy which is the tendency to see the colors green and red as gray, as shown in "Red Starved."
Finn has the ability to mentally fight psychic abilities. The first time is against the Lich's attempt to control his mind. The second time was against Goliad, as he was constantly able to manipulate his thoughts in order to avoid revealing the plan to defeat her, allowing Princess Bubblegum to create Stormo. Finn can focus for a very long time as shown in "Still" when he spends hours telepathically summoning an Astral Beast. As demonstrated in "The Creeps," Finn can lock unwanted memories in "the vault," which is later seen in "King Worm." However, this is a normal human ability occurs where certain memories are removed from the consciousness if is to painful or traumatic for them to recall. Finn also has the ability to read and write, and he can also do simple math.
Finn is proficient in several forms of combat, including hand-to-hand, magic, and swordsmanship. When using hand-to-hand combat, he is an aggressive fighter, combining some forms of martial arts or his amazing swordsmanship skills. Finn prefers overpowering his opponents but when he has to, he is quick enough to understand an opponent's weakness or using his environment to win a fight. He also received training from the old gumball robot Rattleballs which dramatically improved his sword skills and his reflexes to greater levels.
Besides combat, Finn displays many other impressive abilities in handicraft. He has some origami skills, as shown in "Ricardio the Heart Guy," in which he makes Princess Bubblegum a paper crane, as well as in "Marceline's Closet," in which he makes a paper airplane. In addition to that, Finn is shown to be able to construct a sculpture of the Candy Kingdom from his saliva for Princess Bubblegum in "The Real You." Finn is also somewhat gifted at constructing simple machines, such as the catapult in "The Witch's Garden."
Finn enjoys singing; after swallowing a tiny computer, he gains the ability to Auto-tune his voice on command, although he can sing without Auto-tune as well. Apparently, Finn can also play the flute, as seen in "Prisoners of Love," where he plays a short lick before javelin-throwing it at Ice King. Unfortunately, the flute falls apart before it could hit him. Because of this, Finn is not seen playing the flute until "The Lich" as Farmworld Finn and near the climax of "Finn the Human" when he shoves it into Tromo's nose. He is also very good at beat boxing as seen in "It Came from the Nightosphere" and "What Was Missing." In "Gut Grinder," Finn tries to play Jake's viola, but Jake says he stinks. Jake even imitates his foot prints and said "I'm Finn the Human, and I stink at viola." However, during "Death in Bloom," Finn panicked over what instrument to pick, supposedly because he could not play any of them, and settles for sleigh bells. In the episode "Go With Me," Finn is seen playing the lute. In "Daddy's Little Monster," he is seen playing the tambourine.
Finn is very good at playing a video game called Adventure Master, which he and Jake play on BMO from time to time. He can also spit very long distances, as he demonstrates in "Evicted!," when he spits on Marceline, "My Two Favorite People," when he spits on Tiffany's face, and in "Web Weirdos," when he spits at birds flying overhead, while suspended upside down on a giant spider web. In "Dungeon," one of the trials that Jake says Finn would have breezed through is a spitting competition against a goblin-like creature. In "Burning Low," Finn is shown to be able to spit water incredibly high into the air. In "Who Would Win," Finn showers Jake with an abnormal amount of saliva through spitting. He also handles his sword with his right hand, suggesting he may be ambidextrous, able to use both hands with equal skill. This is also seen in "Frost & Fire," where Finn writes with his left and right hands and, occasionally, both at the same time. Finn is able to cook, although he leaves this task mostly to Jake. However, in "In Your Footsteps," it mentions and shows him making Finn Cakes.
Finn and Jake gain magical abilities in the episode "Wizard," but they never use those abilities in any other episode. Pendleton Ward later revealed on his Spring that all of the magic that Finn and Jake gained in that episode was contained in their robes, which were destroyed. Likewise, in "The Chamber of Frozen Blades," Finn and Jake gain ice-ninja skills, but it is unlikely they will use them again because, according to Adam Muto, "They didn't have enough time to commit the incantations and hand positions to memory." Finn seems to speak Latin (as evident in "Morituri Te Salutamus,") although this may be caused by the magical powers of Fight King's arena. In "Daddy's Little Monster," for the first time, he becomes an antagonist by wearing the Nightosphere amulet, although it is only temporary. In The Tower, Finn gains a new mental arm with the ability to interact with the physical world. His emotions seem to cause this, along with the ability of telekinesis. Since it was linked with his emotions, it exploded into a huge arm of spikes when he confronted his "dad," and disappeared when Finn's animosity abated.
Finn is twelve years old at the start of the series and progressively grows older relative to the passing of time in real life. As of "Mystery Train" (March 14, 2011), he is thirteen years old. Finn is shown going through puberty throughout the series. This is seen whenever when he screams as his voice cracks. Finn's voice is noticeably deeper at thirteen than it was at age twelve as a result of his voice actor aging. Episodes with early production codes have Finn with a very childlike voice such as "The Enchiridion!," "Prisoners of Love," "Evicted!," and "Ricardio the Heart Guy."
In an interview in early 2012 (at the end of season three), Pendleton Ward stated that Finn is fourteen.
After the episode "Earth & Water," it was revealed that Flame Princess was fifteen years old. Assuming that they are both the same age (in "Incendium," Flambo and Jake states that she was Finn's age), Finn is then fifteen as well. However they may have been born in the same year but Flame Princess may have an earlier birthday than Finn.
If the original airdate for "Mystery Train" represents Finn's actual birthday, then he is sixteen years old as of "Billy's Bucket List" (March 17, 2014); this is consistent with the way he has been aging throughout the series.

Disguises and alternate forms
In the episode "Puhoy," Finn travels to a realm full of pillows where he cannot escape and eventually starts a new life, becoming an adult and elder. Elder Finn loses his right arm and replaces it with an artificial one.
In the episode "Go With Me," Finn is shown wearing a "lute suit" provided by his friend, Jake, in his attempt to convince Princess Bubblegum to go to the movies with him. It is also shown later in the episode when he tries to get Marceline to go to the movies with him.
Magic Fist is the alter-ego of Finn and Jake that first appears in "Wizard Battle." He is not a real wizard; he only enters the Wizard Battle to prevent Princess Bubblegum from potentially having to kiss the Ice King on the lips as the prize for winning the battle. He wears a blue eye mask, electric-green hood, and a large red robe. Finn is the head, while Jake is the body. See the gallery section for more images.
Finn is transformed into a cat by the Grand Master Wizard when Finn forfeits the Wizard Battle; however, Finn was able to break out of it after becoming enraged by Abracadaniel's decision to take the kiss from Princess Bubblegum.
In the episode "The Creeps," Finn wears a black tuxedo with a blue trimmed collar that has a split tail end. He also has a matching blue bow tie, a gray vest, a brown and tan fox mask over his characteristic hat, and brown "fancy gloves."
Giant Foot Finn
In the episode "Freak City," Finn is turned into a foot by Magic Man who posses as a beggar. As a foot, Finn has great difficulty moving at first, and only musters the effort to make himself fall over. Finn is upset at his physical handicap while Jake tries to make him realize that being a foot is a blessing. Finn is unconvinced, and later becomes motivated to return to his original body after discovering that Magic Man has turned many others into body parts as well. After working with the other victims, Finn seemingly defeats Magic Man as the Super Freak. Magic Man restores Finn and the rest of the freaks to their original bodies.
Zombie Finn looks like Finn, and apparently appears in "Slumber Party Panic." Zombie Finn appears in the bottom left corner of the first window to be broken when the zombies break the barricades. Zombie Finn also appears in the Adventure Time game, Rhythm Heroes. In the game, Finn appears as a zombie just like in "Slumber Party Panic." He seems to be controlled by Marceline in the game, and he is next to two other zombies, a cupcake and a candy heart. He was most likely added as a joke or Easter egg.
In the episode "Trouble in Lumpy Space," Finn turns into a Lumpy Space person after giving the antidote to Jake so that he can return back to his normal body.
By doing this, he turns into a Lumpy Space person as well. Lumpy Finn hates Lumpy Jake.
In "Daddy's Little Monster," Finn puts on the Nightosphere amulet to rescue Jake and Marceline from the Nightosphere. This causes him to transform into a huge, monstrous, demonic form similar to Hunson Abadeer. Afterwards, he tries to pull Jake and Marceline back into the world, but stops after Hunson reverts Finn back into his original form.
Paper plate demon Finn
In "Daddy's Little Monster," Finn disguises himself as a demon in order to sneak into the Nightosphere. He puts on his red pajamas, cuts a paper plate and puts it on his face, and tapes forks to his hat.
Hug Wolf Finn
In the episode "Hug Wolf," Finn is hugged by the Alpha Hug Wolf on a full moon, causing him to transform into a Hug Wolf during the night. When he is in this form, he must go on a hugging spree to fulfill his hug lust. However, in the morning, he does not recall anything he did in the night before. As a Hug Wolf, Finn has shaggy gray fur, heart-shaped hands and feet, and wears torn clothing. He is cured when he hugs the Alpha Hug Wolf which cures her as well.
Alternate Universe Finn (Finn Mertens)
- Main article: Farmworld Finn
In the episodes "Finn the Human" and "Jake the Dog," Finn has a pointed nose, wide eyes, a robotic arm, and a blue sweater instead of a blue shirt. He became like this because of the wish that Prismo grants him.
In the homonymous episode, Finn disguises himself as "Davey" in an attempt to hide from his followers. Davey eventually evolves into his own character, possibly hinting that Finn temporarily develops a multiple personality disorder.
- Main article: Shoko
In "The Vault," it is revealed that the strange, amorphous, ghost that has seemingly been haunting him is Shoko, his former self in a past life, who was horribly mutated before her death. Finn completes her dying wish by returning Princess Bubblegum the amulet that Shoko had stolen from her in the past.
Other past lives
In "The Vault," along with Shoko, a few other of Finn's past lives are shown. He was once a comet, then a butterfly, and a strange blob-like creature.

- In "Dad's Dungeon," it is revealed that Finn cries rarely; only in such devastating situations, such as death or heartbreak (or when he poops as revealed by Jake in Memories of Boom Boom Mountain).
- Finn and Jake frequently use math terms as catch-phrases and at times censors for curse words. However, they are shown to be terrible at math as confirmed in the episode "Slumber Party Panic."

- There is a secret GPS implanted on Finn's ear by Princess Bubblegum, as stated in "Lady & Peebles."
- Finn refers to Flame Princess as his girlfriend for the first time in "Puhoy."
- Each alternate form of Finn has a prosthetic limb, a mechanical right arm. Finn can be seen with one in "Finn the Human," "King Worm" and "Puhoy."

He may obtain a prosthetic limb after the events of "Escape from the Citadel," where Finn loses his right arm, but he regained it in "Breezy."
- Besides Tree Trunks' pies, Finn also likes Wildberry Princess's meat pies.
- Finn likes to make lists to remember things, like in "The Real You" and "Five Short Graybles."
- Finn might be tolerant to high/extreme temperatures, as seen in the episode "Jake Suit" when Jake dipped his head in lava, and also in "Rattleballs," when he sat in a mini-barbecue. This may be because he is already accustomed to heat from his relationship with Flame Princess.
