[[http://en.wikipedia.org/wiki/Fuuma_Kotaro Fuuma Kotaro]] (likely born Kazama Kotaro) was the fifth leader of the Fūma {{ninja}} clan, and one of the most famous shinobi from the Sengoku Era.

Often depicted as TheRival of UsefulNotes/HattoriHanzo, [[ShroudedInMyth little is actually known about him]], mainly because all the clan leaders adopted Kotarō as their name.

The Fūma clan was rumored to have been around since the 10th century and specialized in horseback guerrilla warfare and naval espionage, and Kotarō himself often hired and employed bandits, thieves and pirates for his schemes. They were known for their {{greed}}, and would supposedly do anything for the right price. He served the wealthy Hojo clan along with his 200 ''Rappa'' (Battle Disrupters), using them to create chaos and confusion among their enemies. However, in 1590, Odawara Castle fell after a long siege, and the Fuuma clan was soon disbanded.

Kotaro and the survivors turned to a life of theft, and rumor has it that in 1596 he managed to lure Hattori Hanzo into a trap where he defeated him by setting his boat aflame. However, in 1603, Kotaro's days of plunder and robbery came to an end, as he was captured by an old rival, the Takeda shinobi Kosaka Jinnai and [[OffWithHisHead beheaded]] by the shogunate.

Kotarō Fūma is likely one of the most charming and mysterious characters from feudal Japan. He was said to be 216 cm tall and inhumanly strong. Others said that he was the son of an ogre, or that his eyes were inverted.

In modern fiction Kotarō Fūma tends to be depicted as a flamboyant, demonic-looking ninja, with a penchant for chaos and often [[BlowYouAway associated with the wind]]. Long red hair is also a common feature. The infamous FuumaShuriken is named after his clan, though there's no proof that he actually used such a weapon (not that [[RuleOfCool this actually stops the depictions]]).

!!Portrayals in fiction:
* In ''Franchise/{{Lupin III}}'', the Fuuma clan appear as villains, often targetting Goemon. In the Anime/LupinIIIPart1 series, they're led by a woman named Shinobu. In the movie ''Anime/TheFumaConspiracy'', they're led by a guy with a nunchaku staff. For the TV special, ''Anime/LupinIIITheLastJob'', they're revealed as Italian. (InvertedTrope of McNinja!). Also the ninja dog of Asuka is named Kotarou.
* Manga/{{Yaiba}} fought Kotaro Fuuma, who was revived by Onimaru along with other warriors. He is depicted as a very tall and muscular man with improbable hair, [[ManlyFacialHair a beard]] and a whole arsenal of ninja ElementalPowers and StockNinjaWeaponry. And to really drive the point home, he can also turn into a hawk-man, making his surname (Fuuma means Wind Demon) even more meaningful.
* A Fuuma clan is mentioned in ''Anime/{{Naruto}}'', but no Kotaro look-alikes are seen. The oversized shuriken used by Sasuke are named after the Fuuma clan.
* In ''Manga/SamuraiDeeperKyo'' the member of the Twelve Divine Generals Makora is actually Fuuma no Kotarou, Sasuke's friend and, essentially, an ArtificialHuman with [[CastingAShadow shadow-manipulating powers]] who wants revenge against Sasuke for apparently betraying him. Here he's portrayed by Akio Suyama in Japanese.
* In ''Manga/NabariNoOu'', Kotaro Fuuma is one of the main characters, and an ally of the protagonist.
* In ''VideoGame/SamuraiWarriors'' and ''VideoGame/WarriorsOrochi'', Kotaro Fuuma appears as an imposing, creepy shinobi obsessed with chaos and conflict, capable of stretching his arms like rubber tentacles and spontaneously summoning blades of shadows and fireballs. He's also the archnemesis of Hanzo. His first appearence alone in ''2'' has him taking an HistoricalBadassUpgrade by forcefully becoming the ManBehindTheMan for Ieyasu Tokugawa, killing Hideyoshi before his time, backstabbing the Hojo and taking over Japan by force before growing bored with it and letting the Tokugawa rule, while in ''Warriors Orochi'' he's one of the [[LesCollaborateurs first heroes to spontaneously join Orochi's ranks]] when the latter invades Odawara. By the third game, he tones down his craziness because of the inclusion of Hojo Ujiyasu (and Kai), his boss, but he still remains a creepy ninja.
** Also, in that franchise, alongside UsefulNotes/DateMasamune...he's portrayed by a PlayingAgainstType Creator/NobuyukiHiyama.
** ''VideoGame/NobunagasAmbition''[='=]s crossover with the ''Franchise/{{Pokemon}}'' series, ''VideoGame/PokemonConquest'', retains Kotaro from ''VideoGame/SamuraiWarriors''. He specializes in Dark-type Pokémon, with a special affinity for MasterOfIllusion Zoroark. This creep is possibly as close to AxeCrazy as Pokémon has ''ever'' come.
* In ''VideoGame/SengokuBasara'', Kotaro is a [[TheVoiceless silent]] [[HiddenEyes masked]] mercenary and LivingLegend who fights with two shortswords and a giant shuriken, possessing [[FlashStep incredible speed]]. Though he's rumoured to have demonic heritage, and is ruthless on the job, he's less evil than other depictions.
* A young Kotaro appears in ''VideoGame/Onimusha2SamuraisDestiny'' as an ally and occasional playable character. He's cheerful and he loves exotic and rare gifts, but is distrustful of women, as he was abandoned by his mother as a child and raised by the women of his village.
* In ''VideoGame/{{Persona 2}}'', Kotaro Fuuma is one of the summonable Persona.
* In ''VideoGame/WorldHeroes'' and ''VideoGame/AggressorsOfDarkKombat'', Kotaro Fuuma (as just Fuuma) is a playable character. The main rival of Hanzo in the first, serving as the 'Ken' position of the game to Hanzo's 'Ryu' and guest starring in the latter. He's a brash and fiery ninja. He also is one of the VideoGame/WorldHeroes representatives in VideoGame/NeoGeoBattleColiseum
* In ''Manga/LaughingUnderTheClouds'' the Fuuma clan are the main antagonists of the series, and their leader is named Fuuma Kotaro, though it's just a descendant (whether real or just in name is never clarified) of the original historical figure, as the story is set in the Meiji Era.
* Fuuma, TheLeader for the New Hanzou Academy students from ''VideoGame/SenranKagura'' series is stated to be a descendant of Fuuma Kotaro. She herself is a good shinobi and her family is historically been righteous and good, rather than villainous as most depictions make the Fuuma Clan be. She herself is a redhead like most depictions of Fuuma Kotaro and uses a FuumaShuriken connected to a chain.
* ''VisualNovel/ShallWeDate Ninja Love'' depicts Kotaro is a reserved, [[TheQuietOne quiet]], and serious young man with MysticalWhiteHair. He uses wind powers in keeping with the popular legend, but also uses a rifle and is an able sharpshooter.
* One of the bosses in ''VideoGame/FireEmblemFates'' is a ninja named Kotaro. He's the ruler of Mokushu (Fuuma [[DubNameChange in the Japanese version]]), and an enemy no matter which path you take, as he's trying to play both sides [[AmbitionIsEvil to make his country powerful]]. He's also the one who [[spoiler:[[YouKilledMyFather killed Kaze and Saizo's father (but only Saizo knows this as he kept it secret from his brother)]]]], making it [[ItsPersonal personal]] for the latter. Fittingly enough, [[spoiler:killing him as Saizo makes his death [[KarmicDeath a karmic one]].]]
* Kotaro shows up as a summonable Assassin-class Servant in ''VideoGame/FateGrandOrder''. He's noted to have both foreigner and oni blood because of his clan's attempts at eugenics to create the perfect shinobi. He's generally a good guy and can be very dorky at times (his reaction to meeting Sakata Kintoki is to get some pen and paper to get an autograph and show off his ninja techniques). This is explicitly a result of being summoned as a young, valiant, and righteous ninja; he became more of the ruthless bandit later in life as a result of giving in to the demands of survival.
* In ''Anime/FateExtraLastEncore'', Kotaro has a cameo in a flashback as an Assassin-class Servant with an unnamed female Master. He and his Master quickly get killed by Robin Hood and his Master Dan Blackmore.
* Fuuma Kotaro appears in ''Manga/Brave10 S'' as the sixth challenger for the tournament arc between the 10 Braves and Nobuyuki' champions. He appears as a masked {{Bishonen}} with a body-revealing outfit, [[HooksAndCrooks barbed whips]] and huge, guillotine-like blades on his arms, legs and soles. He fights Sarutobi Sasuke but is eventually defeated.
* ''Series/UltramanTaiga'' has one of Taiga's closest allies, the ninja-themed Ultraman Fuuma who is named after the historical figure of the same name. Said Ultra can even create a FuumaShuriken made of light energy as a FinishingMove!
* ''Manga/TenkaichiNihonSaikyouBugeishaKetteisen'' has Kotaro Fuuma the 5th, a tall and cruel man with a snake-like face... reduced to be the obedient dog of the new head Kotaro the 6th, a tall, red-headed [[GenderFlip amazon]] with large breasts and even bigger muscles who speaks in third person and wields a huge chained dart capable of breaking trees in half, as well as augmenting her physical strength by taking the experimental Fuuma clan poison, the Miyabi Orochi. Originally she was a kunoichi and Fuuma apprentice named Kurenai who was tortured and experimented upon alongside her friend Ao. When Ao perished under the latest poison test, Kurenai snapped and took away Kotaro's eye, name and leadership.
* In a Japanese Creator/{{Netflix}} series ''House of Ninjas'', the nemesis of the Tawaras, a modern-day family of shinobis who are descended from Hattori Hanzo, is the Fuma clan, a rival clan of shinobis whose leader is given the name of Fuma Kotaro. The current Fuma Kotaro is the nineteenth to that title.
