History Main / GratuitousNinja

* ''[[VideoGame/JustCause Just Cause 2]]'' has Ninja being used as henchmen by the corrupt president. Why? [[IncrediblyLamePun Just 'Cause.]]

* ''LightNovel/IsThisAZombie'': What's better than vampires? [[NinjaPirateZombieRobot VAMPIRE NINJA]]!!!

** In ''Series/KamenRiderGeats'', Kamen Rider Tycoon eventually receives a TransformationTrinket that grants ninja powers; and the other Riders can borrow it as well.

* ''Series/{{MADtv}}'' once had a TakeThat sketch directed at Creator/StevenSeagal, with the actor starring in a remake of ''Series/KungFu1972''. When Seagal completely botches Kwai Chang Caine's Zen philosophies, he distracts the issue by shouting "NINJAS!" which causes several ninja to attack him, resulting in a frustrated David Carradine walking off the set.

* In ''VideoGame/Fallout3: Operation Anchorage'', the Chinese army has its hi-tech Crimson Dragoon ninjas with ''VideoGame/MetalGearSolid''-style InvisibilityCloak suits. After completing the Anchorage Reclamation VR simulation, the player can acquire the stealth suit (which is a major {{Game Breaker}}) as well as an electrified sword.

** Another episode had Barney tell Ted the consequences of breaking a bro oath (or "broath", if you will), detailing a story from "ancient Bro-man times" where Julius Ceasar makes "Bro-tus" swear a broath not to have him (Ceasar) assassinated. Bro-tus swears the breath, only to sic a group of ninjas in Ceasar seconds later.

* The ''Wiki/SCPFoundation'' universe has [[http://www.scp-wiki.net/scp-2928 SCP-2928]], which are literally ninja. One of the disciplines of ninjitsu that they use binds them to the idea of what a ninja is, which means that as long as whoever is looking at them believes that actual ninja are stealthy, sneaky, and undetectable, they will be. But if whoever looks at them believes that ninja are [[HighlyVisibleNinja highly visible]], then they stand out like a sore thumb. The Foundation intentionally funded shows that made ninja seem more open and visible to weaken them. Also, according to one of the ninja in Foundation custody, [[Franchise/TeenageMutantNinjaTurtles the turtles are real]], but their creation involved a ''lot'' of cocaine.

* ''WebAnimation/MangaRoom'': In [[https://www.youtube.com/watch?v=UE1Sun7QfBc this story]], protagonist Takeru Konno saves a ninja girl named Miu Tsukino from antagonist Taro Kobukuro, who plans to marry her to take over her village (named "Hidden Cloud Village".). After defeating Taro for a second time, he agrees to marry Miu after banishing Taro's gang.

* ''Fanfic/TheGoodHunter'' has the kunoichi (aka. female ninja). Out of the 223 types of [[MonsterGirl mamono]], which normally include fantasy or mythical races, there are ninja types, apparently. In particular, the very first chapter has Murasaki Natsume, a [[HornyDevil succubus]] ninja, showing up at the Hunter's abode. Alas, her training as a ninja is not enough to prepare herself for the Hunter's ferocious assault.

* The beginning of episode 55 in ''WebVideo/StupidMarioBrothers'' has [[StreetFighter Ryu]] fighting multiple ninja awesomely.

* Sam Grant, the bassist of Music/DriftlessPonyClub, becomes a ninja in the music video for [[https://www.youtube.com/watch?v=3xLSkpF_E8c "Legend of Archery"]]. [[spoiler: [[KillEmAll YMMV on whether or not it's all that awesome...]]]]

** First, the instance on the quote page, where Orson adds ninja to Rumplestiltskin to please Booker and Sheldon. In another episode, those two decide to retell ''The Tortoise and Hare''. They consider turning the tortoise into a ninja, but reconsider, saying "[[WhoWouldWantToWatchUs Who would want to see]] ''[[Franchise/TeenageMutantNinjaTurtles that?]]''"

** Most transformations of the titular Rider in ''Series/KamenRiderBuild'' are based on a combination between an inanimate object and a living organism. Most "organism" powers are based on animals, but a few are human professions instead, and one of those professions is a ninja. The inanimate object power that it's most often paired with is that of a comic book.

** ''Series/KamenRiderSaber'' features an order of European-style knights -- one of which, Kamen Rider Kenzan, is a knight with a ninja theme. The justification is that these Riders get their power from fairy tales and folk heroes, and Kenzan's gets his from the story of famed ninja UsefulNotes/SarutobiSasuke.

* The driving logic behind the ''Film/GodfreyHoNinjaMovies'', which takes existing film and splices in ninja scenes woven into the plot via dubbing and CutAndPasteTranslation.

* ''Machinima/FreemansMind'' adds some to ''VideoGame/HalfLife'', as Freeman mistakes the black ops he faces a couple times for ninjas.

** Any ''Franchise/FinalFantasy'' that uses a ninja job class (or Samurai and Monk for that matter). Occasionally handwaved as a job from a foreign land, but there still seem to be an extraordinary number of ninja running around medieval-Europe-inspired Ivalice in Final Fantasy Tactics, and, as mentioned above, often there's no token Far East village to justify it, mentioned or otherwise.

* The Canadian TV series ''Prank Patrol'', which features the titular group helping various contestants pull off elaborate pranks. The patrol consists of the host Andy and his two ninja assistants. Because, as lampshaded by the announcer in a commercial shown on YTV, "You can't have a good prank without...ninjas?".

* The “awesome” part of the old name for this trope is subverted in ''Fanfic/TheKeysStandAlone: The Soft World''. Four ninjas attack John and Ringo in their hotel room—but the two know they're coming, and while the [[CurbStompBattle very one-sided battle]] is offscreen, the aftermath has the ninjas hanging in ice harnesses on the outside of the hotel, stripped naked and with the words “Don't Fuck With 9000s" printed on them.

* As part of its dependence on the RuleOfCool, ''Pinball/{{Deadpool}}'' heavily features ninjas as opponents of the title character.

* ''VideoGame/BrawlRoyale'' depicts Natalie, its eighth opponent. as a ninja making use of katanas and shuriken. Notably, this is the only time Matt Roszak depicted her as such - her debut in 2005 animation ''[[https://www.youtube.com/watch?v=WI-T9QOdn20 Black Mages 5]]'', her second appearance in ''[[https://www.youtube.com/watch?v=9gqjMoX6smY One More Final Battle]]'' and all of her appearances in the ''VideoGame/EpicBattleFantasy'' series depict her as a mage with a MagicStaff as her weappon.

* ''VideoGame/BrawlRoyale'' depicts Natalie, its eigth opponent. as a ninja making use of katanas and shuriken. Notably, this is the only time Matt Roszak depicted her as such - her debut in 2005 animation ''[[https://www.youtube.com/watch?v=WI-T9QOdn20 Black Mages 5]]'', her second appearance in ''[[https://www.youtube.com/watch?v=9gqjMoX6smY One More Final Battle]]'' and all of her appearances in the ''VideoGame/EpicBattleFantasy'' series depict her as a mage with a MagicStaff as her weappon.

* ''VideoGame/BrawlRoyale'' depicts Natalie, its eigth opponent. as a ninja making use of katanas and shuriken. Notably, this is the only time Matt Roszak depicted her as such - she debuted in 2005 animation ''[[https://www.youtube.com/watch?v=WI-T9QOdn20 Black Mages 5]]'' as a mage, and was depicted as such in the ''VideoGame/EpicBattleFantasy'' series.

* ''Series/PythagoraSwitch'': The Algorithm March's awesomeness is cranked UpToEleven when they started hiring [[http://video.google.com/videoplay?docid=-664493411424324244 ninja]].

* Snake-Eyes of ''[[ComicBook/GIJoeARealAmericanHeroMarvel G.I. Joe]]'' started out as a badass [[TheVoiceless mute]] commando with [[TheFaceless a badly scarred face]] and [[KnifeNut an impressive collection of spike-knuckled trench knives]]. But then, [[TheRival Storm Shadow]] enters the mix, and Snake-Eyes is [[TookALevelInBadass upgraded]] to [[MightyWhitey Ninja Commando From Hell]]. Later in the Marvel run, established characters Scarlett, Firefly, and Zartan were added to the growing ninja rosters.

* Or certain would-be criminals in [[https://www.youtube.com/watch?v=EpZbNAdOy7g Yeovil]], England.
