In Air Gear, there is Spitfire and Aeon Clock and, eventually, Kazu, after Spitfire dies.
While her strengths are more in Black Magic, Lina Inverse of Slayers mostly uses fire Shamanistic Magic to fight—appropriate, given her nature. Also, the most basic and well-known spells for most mages is either White Magic or fire Shamanism.
In Kaze no Stigma, the whole Kannagi family (except Kazuma) use fire magic due to the fact that the first Kannagi made a contract with the spirit king of fire. Ayano even fits the personality aspects of a fire user to a T, being a Tsundere, Hot-Blooded, and Fiery Redhead triple threat.
Shinigami head captain Shigekuni Yamamoto-Genryusai uses the sword Ryujin Jakka (Flowing Flame Blade) but defies the personality portion of this trope by having immense self-control and a calm demeanor. At least in the present day. He was much more thuggish and hotheaded a thousand years ago during the first war against Yhwach. His zanpakuto's release command is "Reduce all creation to ashes, Ryuujin Jakka!" His initial release can create an inferno capable of engulfing an entire valley and anyone even in remote proximity reacts with entirely justified terror. Imagine his Bankai… All of the flames are concentrated into the blade. When it cuts there are no flames; the object is merely incinerated. All of the moisture in Seireitei evaporates. It creates an invisible armor of flame around his body that incinerates anything that gets near him. And its maximum heat is a whopping 1,500,000 degrees!
Fire is also Momo Hinamori's specialty.
And then there's always Shusuke Amagai who was also the Filler Villain.
Yoshino Soma's doll, Goethe from the Bount arc was a fire elemental. And later, after she merged with Goethe, Yoshino developed Human Torch-like powers.
Engetsu, the zanpakutou belonging to Isshin Kurosaki, né Shiba, has a name that means "Scathing Moon" and the shikai command "Burn!", although we haven't seen much of its actual powers.
The movie villains Yang from the 2nd movie, and Shuren from the 4th movie.
Portgas D. Ace is quite literary the embodiment of fire, having eaten the Mera Mera no Mi (Flame-Flame Fruit). He can create fire, manipulate it however he wants, and turn his body into it at will, allowing both for rocket-like flight and letting attacks pass through him. Extra credits for shooting flame beams from finger guns.
Marco the Phoenix can transform into a blue phoenix and can use fire to heal his wounds.
Sanji's Diable Jambe (Devil Leg), which covers his foot in heat, allowing him to set fire to or burn opponents.
Luffy by combining vulcanization and gear second can also use burning attacks.
Kinemon, who can cut with fire as well as cut fire blasts.
In Naruto, all the Uchiha clan members have a natural affinity for fire, though many of them can use other elements as well. In fact, fire is the dominant chakra nature of the Hidden Leaf Village as a whole, and the Sarutobi are another clan who seem to have a natural affinity for it. Some ninjas from other villages can use fire as well.
Uchiha with Mangekyo Sharingan eyes can also use Amaterasu, a special black fire which can burn anything, even regular fire.
Likewise are her villainous counterparts Koan of the Ayakashi Sisters with her Dark Fire attack, and Eudial of the Witches 5 with her Fire Buster move. Hawk's Eye of the Amazon Trio sported the ability to breath fire.
Shizuma Kusanagi from Samurai Girl: Real Bout High School is a Hot-Blooded brawler with fiery moves...that are usually performed with alcohol and a disposable lighter. The important thing is it still works like Kyo's moves do, and they still involve a great deal of physical exertion.
Hiei from YuYu Hakusho is this trope all over, being a fire youkai and all. He first demonstrates this ability by incinerating another fire youkai (Zeru), who had been hyped up as being pretty powerful. Rando can also throw fireballs because he stole the technique.
To show you the difference between their levels: though he claimed to use "demonic fire", Zeru was only limited to flames in the human world; Hiei, on the other hand, because of his transplanted Jagan Eye could also control "Darkness Flame": the living black flame of the demon world Makai.
Fiamma of the Right is the most powerful human villain the series' protagonists have faced so far. His ability, "The Holy Right", manifests in the form of a flaming third arm behind him, allowing him to perform incredibly broken acts like conjuring a forty kilometer longFlamingBFS and flames which destroy objects without any destructive force.
Phoenix King Saffron from Ranma ½. He doesn't just project fire, it healshim.
The Festival arc of Mahou Sensei Negima! gives us Mei Sakura, who is also a fire magic specialist, and the significantly more competent Chao Lingshen, who, after releasing the seal on her magic, reveals herself to be scarily powerful at it. Later on, the main hero's childhood friend Anya displays this ability. From the arc following it is Homura, one of Fate's loyal minions and number four in the series he comes from, Quartum, Averruncus of Fire.
One of contractors' power in Darker Than Black is massive pyrokinesis. This would not be that bad...if it were so easily triggered instinctively or the contractor in question wasn't a little girl prone to emotional overreaction and rolling downhill into long, dreamwalking trances. Another contractor caused, at will, fiery explosions of handprints he previously left on something. Which is spectacular when the boy bothers to mark with his skin fat everything in a room.
In Part 3 of JoJo's Bizarre Adventure, Muhammad Avdol's stand, Magician's Red, has the ability to conjure and control flames. Strangely enough, his flames also seem to be useful at binding people.
Jacqueline O. Lantern Dupré from Soul Eater has the Weapon form of a lantern that doubles as a flamethrower. She can also generate fire without fully transforming. In fact, the trio of Ox, Kim, and Kirikou are fire and lightening based: Harvar is an electricity-generating lance, and Pot of Thunder and Pot of Fire's powers are what their names suggest.
Kämpfer: Natsuru uses fire powers as his Zauber ability.
Kara no Kyoukai has Azaka Kokuto, whose fire abilities are shown in the 6th chapter.
Fatina from The Tower of Druaga is a fire mage who channels her magic through a magic gun/flamethrower.
Played with in Katekyo Hitman Reborn!. Certain people have the ability to use Dying Will Flames, which can be one of seven types that correspond to a weather phenomenon and have a special property. Subverted in that some flames have a property that seems more like another element, namely, Rain Flames and Lightning Flames.
In the manga, seven more flames are added when the Simon Family enter the story. The new Earth Flames (as opposed to the Sky Flames) correspond to themes associated with the Earth such as Flames of the Forest, Glacier, and Mountain.
In the anime Dragon Crisis!, we have Rose, a cute loli with a strange necklace—who is also able to throw fire.
Renkotsu of the Band of Seven in InuYasha is a firearms expert who seems to love blowing stuff up and even breathes fire with his explosives and other equipment.
Homura in Sekirei, against personality type, is one of the more stoic characters. The Hot-Blooded Tsundere is the water Sekirei, Tsukiumi, who exhibits the remainder of this trope.
Rin, aka Cure Rouge, from Yes! Pretty Cure 5. Even her hair is shaped like a flame when transformed!
Two characters in Tiger & Bunny can create/control fire: Flamboyant superhero Nathan Seymour/Fire Emblem and criminal-killing vigilante Yuri Petrov/Lunatic. Both avert the standard Personality Powers for fire as Nathan is cheerfully camp and Lunatic is unnervingly calm both in and out of costume.
In the manga version of Tokko, Sakura's Sword Beam attack seems to be fire-based. Also, Ito is shown to be able to make a giant flaming hand shoot up out of the ground.
Gurren from Shonen Onmyouji uses the fires from hell in his attacks. He's considered the strongest out of the 12 shikigami in terms of attack power.
Yu-Gi-Oh! has Joey Wheeler/Katsuya Jonouchi; his favorite monster is the Flame Swordsman.
Yu-Gi-Oh! GX has Axel Brodie/Austin O'Brien; his Deck utilizes the Volcanic archetype.
Yu-Gi-Oh! 5Ds has Hunter Pace/Mukuro Enjo; his Deck utilizes the Burning Skull archetype.
Pyro, an X-Men villain. His mutant power allows him to control fire, but, notably, not create it; in the comics and the third movie, he uses a specially designed harness to produce flame, but in the first and second movies, he used an ordinary lighter.
The Ultimate Universe Pyro is not immune to fire and is horribly scarred all over his body.
Johnny Storm (the second, but more famous Human Torch) from the Fantastic Four. The original hothead.
Frankie Raye had powers similar to the Torch's, and her powers were augmented to cosmic levels when she became Nova, a Herald of Galactus.
The Golden Age Torch was an android who accidentally burst into flame on contact with air. He later gained control over his powers, became a superhero, and picked up a sidekick, Toro, who was also on fire, but a human boy mutated by radiation rather than an android.
Tara, a Distaff Counterpart to the Golden Age Human Torch, is also an android who bursts into flames. Unlike The Golden Age Torch, she never gained full control over her powers, so she was given a special suit so she could "flame off".
The Golden Age Human Torch was sometimes impersonated by Captain Kerosene, who had similar powers.
Super-Skrull has this power as well. Since he has all of the F4's powers.
Liz Sherman from Hellboy. As it turns out in the comicbooks, she actually has some kind of free-willed elemental fire-spirit living inside her, hence her occasional Power Incontinence.
Magma from New Mutants controls fire in addition to lava, so she's kind of a Fire/Earth elemental.
And various versions of Sunfire, as well.
Matchstick, a mutant at the Xavier school. Part of his mutation is that his head is permanently on fire.
School rioter Glob Herman's body was made of a gelatinous substance that could also be set on fire (until he was extinguished). The "setting on fire" part was taken care of by fellow rebel student Redneck, who had actual fire powers.
Fever Pitch, another mutant fire guy. His powers eventually destroyed his body, but his flaming skeleton continues to walk among us, fully alive.
Fever, late of the Doom Patrol. Well, she had the power to increase the temperature around her and she was invulnerable to the heat, so invariably, she would light herself mostly on fire. She's a spacey Cloudcuckoolander, though. Well, until being imprisoned on Apokolips made her Darker and Edgier, that is.
One of Crazy Jane's multiple superpowered personalities is the gigantic "Sun Daddy" who shoots fireballs out of her flaming head. There was also Flaming Katy, who had more conventional fire powers.
Effigy, a Green Lantern villain, had powers that worked kind of like a Green Lantern Ring, but with fire instead. He was originally intended as a Sinestro-style Evil Counterpart to the then-new (and very pyrophobic) Lantern, Kyle Rayner.
This is the gimmick of several DC villains, most notably Heat Wave, who is an extreme pyromaniac who burned down his home as a boy and designed a pocket flamethrower and fireproof suit so he could handle fire better.
Similarly, Batman villains and pyromaniac arsonists Firefly and Firebug, who actually have nothing to do with each other.
And the Human Flame, a small-time crook brought down by the Martian Manhunter decades ago. When he got out of the joint, friends in high places let him get revenge by roasting MM alive. The Human Flame's suit shoots fire from nozzles located on its chest, leading to jokes about him having "fire nipples".
And minor villain Vulcan, as part of his group's Greek mythology theme.
Fire Lad, of the Legion of Substitute Heroes, could breathe fire. He was rejected by the Legion of Super-Heroes because he couldn't control his powers very well; a recent version of him had his powers officially listed as "breathes fire with at best moderate control."
Sun Boy had more direct, Human Torch-style fire abilities (and a way with the ladies not unlike Johnny's). Wildfire, a little, as well.
DC heroine Beatriz DaCosta, also known as Fire. Unlike most other fire wielders, her flames burn green, and, even de-powered, her hair is permanently bright green.
A number of minor Marvel Comics supervillains possess this power. Firebrand was a radical political anarchist who created his own suit of flame-blasting armor to battle Iron Man, the second one stole the battlesuit of the first and went on to battle Spider-Man and a few B-list heroes, and the third was mutated by a horrible lab accident and essentially became a Psycho Electro, except with fire. Another notable example is the supervillain Solarr, who possesses the ability to absorb solar radiation and convert it to blasts of fire that he can control. Using this ability to become a supervillain, he would later go on to battle Captain America, Spider-Man, Daredevil, and Alpha Flight.
In Superman, Chris Kent's girlfriend, Thara Ak-Var, has pyrokinesis in addition to standard Kryptonian powers. She can harness fire even if being stunned by kryptonite, red sunlight, or some other Kryptonian weakness.
In Empowered, Willy Pete's body burns hotter than the sun, and he can fill a building with flames before anyone even knows he's there. Don't ask how he takes advantage of his powers.
Flame, from Wonderworld Comics, can control fire and even burst into flames.
Vulcan, from Super-Mystery Comics, can control fire and is effectively bulletproof since the bullets melt before hitting him.
Fireman, from Liberty Scouts, can control fire and even turn into glass.
Fireball, from Pep Comics, can control fire and uses his abilities to fight arsonists.
Red Blazer, from Pocket Comics, also had fire powers.
Thor has created fire blasts and expanding fire waves with Mjolnir. The hammer can also be used to absorb fire-based attacks, while Thor himself has withstood Ghost Rider's hellfire, Heimdall's cosmic fire, and the Super Skrull's nova blast for extended periods.
Likewise, Surtur, Lord of the Fire Demons of Muspelheim, can produce massive amounts of fire akin to stars.
Taranee Cook from W.I.T.C.H., who averts the firey personality aspect by being shy, bookish, and the brainy one.
She still has a temper: as Cedric put it when Elyon asked him to stop a furious Taranee, "I can't! The Power of Fire is the most untamed of all! Run away! RUN AWAY!". It gets better: Cedric cried that when Taranee got furious and started melting the supposedly fireproof bubble she was imprisoned into, and he rebuked Elyon because he told her not to provoke Taranee.
The titular team in Wildguard features two heroes with this power: Ignacia and Freezerburn. This clashes with Superhero Speciation standards, especially since Freezerburn also having An Ice Person powers causes many people to write Ignacia off as redundant.
Surprisingly averted by Nedor's Pyroman — he actually has electrical powers.
Chi is the least stoic and solemn of the Warriors of Virtue. Though he also represents Wisdom, he's still eager and impulsive: "Patience is not my virtue."
Wilder and Wallace in Wilder Napalm
Pyro from the X-Men series can manipulate existing fire.
Liz Sherman in the first and second Hellboy movies has pyrokinesis, but is unhappy with it and has difficulty controlling it (she burned down an entire city block and killed her family as an eight-year-old). Ultimately, she is able to embrace it and, in the second film, has greater control and is in a relationship with the luckily fireproof Hellboy. Oddly, Hellboy has the fiery, impulsive, and chaotic personality, while Liz is comparatively stable and reserved.
The alicorn (unicorn horn) allows its holder to start fires and throw fire.
In the climactic fight with Jack, Darkness repeatedly fires fire out of his hands and weapons he's holding and causes fire to blaze up at a distance.
In The Quest of the Unaligned, aeshes (fire-aligned mages) are an example of this trope. As an example, Laeshana, one of the book's main characters, has a fiery personality that accompanies her literal fire powers that results in her arguing with powerful governmental figures and "flaming" herself unconscious.
The little girl at the beginning of the first book in the Gone series.
Lord of the Rings: Gandalf, servant of the Secret Fire and wielder of the Flame of Anor (which may or may not have to do with bearing Narya, the Elven Ring "red as fire"). However, he needs wood to sustain a fire, as he cannot burn snow.
In the battle that cost him the Ring, Sauron's body was described as blackened from the immense heat he gave off and even set people who got too close to him on fire.
Harry Dresden from The Dresden Files prefers fire evocations, with a minor in wind and force, except for a period where, after being horribly burned with a flamethrower, he actually became pyrophobic. There was also the time period where he had a fallen angel living in his head that granted him access to Hell Fire. The Hellfire has since been replaced with Soulfire, which is sort of Hellfire's opposite number. Instead of being like a really bad bank loan, with immediate payoffs but nasty costs later, it's more like an investment; the costs are immediate (using it dips into his actual specific soul, draining life force which may or may not grow back), but the gains are much greater and more constructive than the brute force of Hellfire.
It should noted that for human base magic, Harry uses "Fuego" as his magic word to summon fire because of the mental connection he makes between it and the power. If he used English words, such as "fire" every time he thought or said "fire" cue summon. So one time when Harry was truly and righteously pissed at his enemy, he cried out "''Fuego. Pyrofuego!'' '''Burn!'''"
Charlie McGee from the Stephen King novel Firestarter is a pyrokinetic. She can set pretty much anything on fire, even fireproof materials, and doesn't appear to have limits; her problem is stopping.
Also, from the same author, Carrie had various powers, including psychokinesis and pyrokinesis.
According to the Other Wiki, this is the book that coined the term 'pyrokinesis'.
Among the most commonly used spells in the Sword of Truth series is Wizard's Fire, which acts a lot like napalm. Used to greatest effect in the sixth book, where Zedd and another wizard decide to show an enemy army "an old fashioned fire fight"; They hurl fireballs the size of houses at the enemy army, killing thousands in moments.
Lavan Firestorm from Brightly Burning. He even has to get mad before his powers will manifest at first; fiery temper, indeed...
Elsewhere in the Valdamar stories, it's mentioned that self-taught magic users typically figure out how to call fire as their first spell. An evil wizard uses this tendency to set a trap at one point...
Some of the more powerful Anne Rice vampires have the Fire Gift, which basically amounts to pyrokinesis. In the Queen of the Damned, Akasha uses this to eliminate most of the world's other vampires and also pass the Fire Gift on to Lestat by allowing him to drink her blood.
In Codex Alera, firecrafters could generate enormous bursts of flame and heat or otherwise control fires. They also have the ability to evoke powerful emotions in others, such as anger or terror; the best orators in Alera are firecrafters for this exact reason.
In Mystic And Rider and its sequels, Senneth has enormous power to light and put out fire and is constantly warm. She loses her power in the fourth book but regains enough of it to light a small flame or, by the fifth book, put out all the lights in a room.
In The Guardians, Each Guardian has a unique Gift related to their life. Alejandro's Gift is creating, manipulating, and shielding from fire, which works well in tandem with his ex-lover's Gift of metal.
In the Harry Potter series, it's strongly suggested that Albus Dumbledore's weapon of choice is fire. Amongst other things, he uses fire to intimidate the young Tom Riddle and to fight off the Inferi guarding the fake locket in The Half-Blood Prince.
Many Adepts in the Savage Empire book have pyrokinetic talents.
Leo from The Heroes of Olympus is one of the few sons of Hephaestus to have the ability to create and control fire.
In Artemis Fowl, all goblins can generate fireballs at will. A bit of a subversion, as while their skin and internal surfaces open to the air (such as the inside of the nose and moth) are entirely fireproof, they can still be damaged when the fireballs detonate (as demonstrated in the first book when a goblin sucks a fireball up his nose in order to blow it right back out but is thwarted when his nostrils are blocked and the fireball explodes inside his oral-nasal cavity).
The first screamer we see in the web-novel Domina has this power. She doesn't use it much, though—probably because she's a near-mindless zombie.
Pyromancy is one of the "legal" magical schools in Shadow Ops. It is also one of the most powerful and destructive schools, though it lacks any of the other elemental schools' versatility. All a pyromancer can do is create flame in various amounts and generate mindless fire elementals, though their ability to do so makes them one of the more valued schools if only through sheer, literal firepower.
Fire is the second Elemental Magic that each of the twins learns in The Secrets of the Immortal Nicholas Flamel. Sophie learns it in the second book from the Comte St Germain and Josh learns it in the fourth book from Prometheus (yes that one). It's also revealed that Prometheus's fiery Aura brought the very first humans to life.
Trapped on Draconica: Daniar can breathe fire because she's a dragokin, i.e. a human blessed with dragon powers.
Lindsey Stirling's "Elements" features a lot of fire that she dances around, based in a frame quickly constructed from Home Depot materials.
Rammstein. Shows include flamethrowers, fire-shooting masks, massive fireballs errupting from the stage, instruments shooting sparks or bursting into flames... One of their most famous gags involves singer Till Lindemann rising from stage engulfed in fire. And they would use that in their opening number.
Mythology And Religion
Hephaestus from Greek Mythology is the god of fire, as well as the god of the forge. Sometimes, the three solar dieties (Hyperion, Helios, and Apollo) also are associated with Fire, if not with Light. Also, a well-known myth tells of the Titan Prometheus, who stole fire from the gods to give to mankind.
Surtr, Lord of the Fire Giants from Norse Mythology. Also, sometimes, Loki.
The goddesses Sekhmet and Wadjet and various serpents of the Duat (underworld) in Egyptian Mythology.
One of the most common elemental damage powers in Dungeons & Dragons, with such favorites as the Wizard's fireball spell, the flaming sword, fire traps, the red dragon's breath weapon, and so on.
The pyrokineticist prestige class embodies this trope.
Strangely enough, the Druid class is prone to this trope, gaining spells like Produce Flame, Flame Sphere, and Flame Blade within their first few spell levels. If that's not enough, Wild Shape lets them take the forms of elementals, including, yes, FIRE.
Don't forget Hot Hands.
Ironically, fire is also the most commonly resisted damage type, leading it to being shunned by dedicated powergamers in 3rd edition in favor of sonic damage.
The Path of the Brilliant Flame fu path from Feng Shui essentially gives you fiery kung fu powers. And fire is one of the most common Blast powers that a sorcerer can use.
Jaina Stormborne from the Fantasy Strike games sets herself on fire in addition to the usual flame attacks. In Yomi, she also sets the arena floor on fire.
The Firestarter Battlemech from BattleTech is dedicated to the role, mounting four fusion-powered flamethrowers.
Eldar of Warhammer 40,000 who embrace the Fire Dragon Aspect do so to embrace uncontrolled destruction and mayhem. Appropriately, they grab the biggest fusion gun they can find as their weapon of choice.
Ork Burnaboyz tend to be rather obsessed with setting things on fire, carrying large famethrowers and sometimes etting other boyz on fire to see em "do da burny dance".
The Inquisition loves flame-spewing weapons, allowing for easy execution of Burn the Witch!.
Signature weapons of the Adepta Sororitas.
It seems a lot of psykers like this now, since 6th edition adds in Pyromancy as a universal psychic power pool, as an option for many races that use psychic powers. It all depends on the player, really.
Its Fantasy counterpart Warhammer has an the Lore of Fire, an entire school of spells specifically that use Fire.
In 7th Sea, there is the rare sorcery "El Fuego Adentro" of Castille, where a practitioner can create and wield fire. Just don't let the Inquisition find out...
In Heavy Gear, the Flammjager gear was not only a specialised incendiary mecha, but its pilots had a (justified) reputation as Pyromaniacs.
The Pyrokinetic mutant ability in Paranoia. Of course, thisbeingParanoia, if it's actually helping at any point, the GM will probably cause the pyrokinetic to cook off the grenades he's carrying or otherwise inflict hilarity on the hapless fellow.
Call of Cthulhu. The Great Old One Cthugha and his Fire Vampire servants can perform fire-based attacks.
There's several subspecies with this power in BIONICLE, though some of the more notable characters are Tahu, Vakama, and Jaller. More often than not, they're The Leader of their group.
Mass Effect 2 and Mass Effect 3 give you several flame-based powers. Against the 80% of enemies who aren't robots, these are the deadliest attacks in the games.
Incinerate: Engineer and Infiltrator Shepard each get this as one of their basic powers, as do Mordin in the second game and EDI in the third. Miranda gains it in the final DLC.
Incendiary Ammo: given to Soldier and Vanguard Shepard, as well as Grunt and Jacob in the second game and James in the third.
Inferno Grenade: Zaeed's bonus power in the second game, which you can give to Shepard after you unlock it, and one of Ashley's powers in the third game.
In the third game, Engineer Shepard's heavy melee move is him/her stabbing the enemy with a flaming omni-blade.
Also, in the third game, one of the upgrades for the Sentry Turret power (possessed by Engineer Shepard) gives it a flamethrower.
The incinerate plasmid from BioShock lets you set fire to your enemies with a snap of your fingers. The chemical thrower with napalm ammo has similar effects.
The "Devil's Kiss" vigor of Bioshock Infinite lets you toss a fireball out like a grenade. There are also the Firemen you fight from time to time, who carry a personality as fiery as their attacks.
Kyo Kusanagi, his father Saisyu, Iori Yagami, Ash Crimson, and most of the Kyo clones from The King of Fighters. K', particularly.
Orochi Chris (but not Chris as Orochi) used fire, too, cementing him as the New Faces Team's Kyo counterpart.
Shingo Yabuki, Kyo's protege, is under the impression that he can actually "shoot fire" under certain conditions, but he totally can't.
Sho Kirishima, the original concept version of Kyo, has similar abilities (and a more exaggerated personality).
Also, one of Kyo's strongest moves involve him being a Man on Fire, and if an opponent stands close to him before he launches the attack (since the attack can be held), they get damage - even more if their moves are countered. If Kyo's opponent takes that attack head on and gets countered - it's enough for a KO. Then again, who takes that attack head-on...
In The Elder Scrolls V: Skyrim, you can shoot fireballs, emit a constant stream of fire from the palm of your hand, lay fire rune traps, enchant your weapons to do fire damage and cause a huge explosion by hitting the ground with your fist. You can even breathe fire if you find the Word Wall that contains the Dragon Shout (or learn it from Paarthurnax).
Sure, psyblasts and levitation are probably more useful than pyrokinesis, but setting squirrels on fire with your mind is one of the best parts of Psychonauts.
Billy Kane in Fatal Fury can channel fire through his bo staff. Ironically, he hates smoking.
In Fatal Fury 2, Mai Shiranui comes in with an arsenal of flame-based attacks, which she has retained since.
And then there's Kim Jae Hoon and Kevin....
Stahn Aileron from Tales of Destiny thanks to the Swordian Dymlos, who also specialized in fire when he was still human. His son, Kyle Dunamis, is surprisingly more variative in element.
Alvin from Tales of Xillia can use all six elements, but his strongest attacks and his mystic arte use fire. Milla is supposedly a master of all elements but specializes in fire alongside wind, light, and lightningnote Fire and Wind combined Agria of the Chimeriad is the fire specialist in their Four Element Ensemble and Gaius uses a fire-themed mystic arte despite his main element being light.
Yukimura Sanada, Shingen, Nohime, Chosokabe Motochika, Toshiie Maeda, Magoichi Saika, Hisahide Matsunaga, and Xavi from Sengoku Basara. Hideaki Kobayakawa may count as well.
Fire is the element that draws from the Red Moon in Skies of Arcadia, and it also provides status buffs. Vyse has the second-weakest magical power in the game (the weakest being Drachma), but he can learn all of the fire spells quicker than the others. And though Aika learns nature spells the quickest, all of her Super Moves are fire-based.
And from Mega Man X, there's Flame Mammoth, Flame Stag, Magma Dragoon, Mattrex/Burn Dinorex, Blaze Heatnix, Flame Hyenard, and Burn Rooster. X3 is the only game in the series without a fire-elemental boss.
Fire Leo from Viewtiful Joe. Joe himself gets fire powers from using his fast forward ability.
Main character Batsu Ichimonji from Rival Schools has a Super Mode in the sequel Project Justice, Burning Batsu, which gives his ki fire-like properties.
Also, several other characters bust out with the occasional fire attack; Robo-Ky, Axl, Faust, Potemkin, and Bridget all have fire attacks. Sol's the most common, as almost all of his special moves light opponents on fire.
Bang Shishigami from BlazBlue. His Drive attack is pretty much the only thing in the game that sets the enemy ablaze.
If you look closely, some of Ragna's powers and attacks look vaguely flame-like.
In the Dissidia series, Cloud specializes in the Fire line of spells, since, unlike nearly other character with black magic spells, Cloud *only* uses the Fire line, and is the one of the few characters in the game to have more than one or two tiers of a spell line.
The Kirby series have their fair share of fire-starters:
Kirby's Adventure introduced recurring foes Flamer, Hot Head, Fire Lion, and (one half of the Mr. Shine and Mr. Bright duo) Mr. Bright.
Kazuki, Kyoshiro, and Tam Tam from Samurai Shodown. Kazuki's special moves all involve fire (except for Bust Kazuki, which is more about exploding), breathing fire is one of Kyoshiro's signature special moves, and Tam Tam can also cough up fireballs of varying intensity. Sieger's moves sometimes burn opponents, but that's because his gauntlet uses gunpowder.
While the Pyro from Team Fortress 2 usually attacks with a flamethrower, two of his taunts (Hadoken and Armageddon) have him seemingly creating fire from his own body.
Ignus from Planescape: Torment, who has been turned into a living conduit to the Plane of Fire. And likes it.
Dhalsim from the Street Fighter series breathes fire as one of his special moves. His ability comes as a gift of Agni, the Hindu god of fire.
Ken likes to set opponents ablaze with his Dragon Punch, while Fei Long does the same with his Dragon Kick.
In some games, Ryu can produce fire Hadokens as well.
Gill, when he hits you with the fire half part of his body (the other half is ice).

Scorpion is fond of breathing fire (especially as a fatality).
Sonya Blade is also known for setting opponents ablaze with her signature fatality.
Shang Tsung and his penchant for hurling flaming skulls at people and sending gouts of fire shooting up at people during his fights (when he's not morphing into other fighters, that is).
Garet and Jenna are the Mars Adeptsnote individuals utilizing fire-based Psynergy present in Golden Sun and Golden Sun: The Lost Age, with fiery personalities and red hair, to boot. The villainous duos of each game (Saturos and Menardi in the first game; Agatio and Karst in the second game), hailing from a fire-wielding clan, also fall under this trope. The third game, Golden Sun: Dark Dawn, has Garet's son Tyrell picking up the torch alongside Eoleo, who's element was previously something of a mystery.
In Pokémon, Kanto Gym Leader Blaine, Hoenn Gym Leader Flannery, Sinnoh Elite 4 member Flint, Unova Gym Leader Chili and Kalos Elite 4 member Malva all specialize in using Fire-type Mons. All Fire-type Pokémon also qualify, with certain Pokémon capable of using Fire-type moves like Flamethrower despite not being actual Fire-types (such as the Dragon Pokémon Dragonite).
Several Legendary Pokémon are pure or part-Fire type, such as Ho-Oh, Moltres, Entei, Heatran, Reshiram, etc. Groudon from Pokémon Ruby and Sapphire is technically Ground-type, but still has something of a fire theme going, with moves like Eruption and being associated with lava and volcanoes, as well as the ability Drought that summons permanent sunlight to boost Fire-type moves.
Yukiko Amagi from Persona 4 also has fire magic with her persona, but unlike Junpei, she focuses herself more on magic power, thus her fire magic usually does more damage. With Yukiko, it's particularly ironic, as her name means "snow child".
Mononobe no Futo briefly shows it during one of her spellcards, as part of her "manipulation of Feng Shui" power.
City of Heroes includes a fire-based set for pretty much everything - melee, ranged, buffs and debuffs, control...
There's also the Hellions, the demonically-themed gang of pyromaniacs you start off fighting against. Blood Brothers and Fallen have resistance to fire, while bosses from this gang have full-on pyrokinesis.
Warlocks and Mages in World of Warcraft both have a talent tree that specialises in fire damage. Shamans have some fire spells as well, although they primarily use lightning magic. Fire mages also tend to have much less survivability than Frost.
One of the Elementalist skill sets in Guild Wars is Fire Magic, though it's the most single-minded skillset of the class, focusing on one thing: damage, and in large quantities.
Adell and Raspberyl from the Disgaea series specialize in fire techniques. Red Skull and Mage classes also use fire spells.
The Dragon, Entei, and Ifrit monster classes all specialize in fire attacks, as well (save for the first game, where the former two used attacks of whatever element they had an affinity for). The Dragon mostly uses it as a Breath Weapon, while the latter two manipulate it in a more spectacular fashion.
Subverted in Tsukihime with Akiha. The description of her power mentions the burning sensation as though you're on fire and that, if you can see it, it looks like thin burning red lines coming at you. She's a bit of a Fiery Redhead when using her power and is also prone to 'kill it now ask questions later'. However, her power is actually something called Plunder and apparently involves the absorption of life energy itself.
All the units with some sort of firepower in the Command & Conquer games. Given that warfare is a major aspect and firepower is prevalent for most offensive units, some really are adept at the term. Look at the Flame Tanks and Flamethrower Infantry in Tiberian Dawn. Not only do they dish out massive damage at enemy infantries, but when your unit with flammable weaponry is killed, it goes up in massive flames, thus inflicting moderate damage on nearby units and structures, whether friend, foe, or neutral. This trait is also noticeable on GDI Grenadiers, but the resulting explosion is of a lesser degree.
This trait makes a comeback in the Flame Towers, Flamethrower Infantry, and Grenadiers of the Soviet faction in Red Alert. In the Aftermath expansion, the Demolition Truck is available as a deliberate suicide unit; get these suicide bombing trucks out of your base right when you can, because once it explodes, the explosion is of a massive size.
Karnov, Russian strongman and one-time mascot of Data East, breathes fire.
Every single boss in Donkey Kong 64 except King K Rool. Really, even the fish boss shoots quick barrages of fireballs as it's main attack. Usually in combination with lasers.
Cliff and Duster from Slightly Damned have the 'Siara Special'. It's powerful enough to ruin even a high-ranking Angel's afternoon. To a lesser extent, J has a tendency to make anything he touches explode.
Later, it is revealed that she, like her mother, are actually descendants of a Fire Elemental/Human pairing, and thus have a bit of supernatural fire burning inside them. Coyote makes a bit of a point out of the fact that, while she can generally be mistaken for an Emotionless Girl, the right prompting can cause Annie's temper to 'flare' with REMARKABLE speed.
Pacificators Cinna is a rank B, and Kathy a rank Elite (Elite is the highest possible rank. B is the third highest). Renegades Shiva, who is the only character capable of a second power, is an unknown low type and Yuma is a type 7 (the lowest is 1, the highest is 10). They all have to have fuel of some kind with them; it's impossible for them to generate fire without fuel and oxygen.◊ They also carry bombs with them◊ (only the Elite-ranked Pacificators are allowed to carry liquid fuel with them).
Having the power of fire isn't all that awesome, though. They overheat if they get too angry.
In When She Was Bad, Gail temporarily gains pyrokinesis as her unstable, constantly-changing secondary superpower.
From the Global Guardians PBEM Universe: Heatwave, Starfire, Fire Drake, Ablaze, Firefall, Fireworks, Flashpoint, Inferna, Hotshot, Centigrade (who is also An Ice Person), Incendie ("Blaze" in French), Mondfeur ("Moonfire" in German), Ulkataranara ("Comet Man" in Hindi), Matahari Merah, Firebird, Playma ("Flame" in Russian), Salamander, Sunfire, Wildfire, Flame, Ifrit, The Confessor, Morningstar, Komet, Molotov, Inferno, Fuoco Bianco ("White Fire" in Italian), Pumpkin Jack, Tourmaline, Pyro, Dragon, and Red Devil.
In the Whateley Universe, Fireball. And Sparkler, after she gets her power gauntlets in the first Ayla story.
In "Christmas Elves", Fey quite literally plays with fire — and then turns it back on the mooks who thought using flamethrowers against the reincarnation of a Sidhe queen on excellent terms with fire elementals back in the day was a good idea.
Chronicles of Syntax has Shia, who can manipulate her own thermal energy to create and control fire. Unlike some other examples, she's neither a redhead not hotblooded. In fact, she can be quite the Cloudcuckoolander at times. Unless she's actually trying to kill you, in which case avoiding fireballs becomes a necessary skill.
Frollo has command over pyrokinetic magic, as well as a fireplace that doubles as a TV and computer, on The Frollo Show.
Worm has a few, most notably Burnscar, a member of the Slaughterhouse Nine, who can create intense fires and teleport between flames. The more fire she uses, however, the more damaged and weakened her emotions get—and she's already pretty unstable, having joined the Nine after escaping from a mental institution.
Firebenders in the Avatar franchise, obviously. The interesting part is that not all of them fit the hot-tempered mold that usually goes along with fire powers, given that they are an entire culture. Zuko is plenty hot-headed, but his sister Azula is more cold and cunning, which her blue fire reflects. Their father Ozai is somewhere in between, while Iroh has the personality of a warm campfire.
Aang, on the other hand, once he accepts that Firebending is not Bad Powers, Bad People, comes fairly close to Iroh's version of this, though he does become considerably more focused; it's implied that Firebenders have a tendency to become overly intense and Determinators.
The Fire Nation's philosophy of firebending via rage plays a part in their hot-headed tempers; a subset of firebenders who split off from the nation passed onto Iroh, Zuko, and Aang the original, life-affirming form of firebending that averts the need for firebenders to be Hot-Blooded to use their powers. It is indicated that this style of firebending allows for far more control than rage-bending does.
Then there's Mako from The Legend of Korra, who's pretty much The Stoic ("cool under fire," as a sports announcer puts it). Korra herself fits the Hot-Blooded stereotype and it's interesting to note that she will default to fire even though she's a Waterbender by birth.
Taranee Cook from W.I.T.C.H., again. Like her comic book self, she is no hothead, instead being reserved and intelligent. Also, before she got her powers, she was afraid of fire.
The Decepticon Firecons in The Transformers, especially the moronic pyromaniac Cindersaur and the even more moronic pyromaniac Flamefeather; Their supervisor, Sparkstalker, not so much, being a strategist at heart.
In the Viewer Mail 1 episode of Family Guy, Chris has this power.
Lucius on Jimmy Two-Shoes sometimes shows the ability to do this, but it's mostly treated as a Running Gag when he's angry. Word of God says he has some powers he refuses to use out of pride. Presumably, this is one of them.
Blossom's special power in The Powerpuff Girls is the ability to breathe fire and ice, although it tends to switch depending on the weather and her body temperature. (She doesn't use it much, though.)
