[[AlternativeComics Indie comic book]] turned [[CashCowFranchise multimedia empire]], starring the eponymous Teenage Mutant Ninja Turtles.

''Teenage Mutant Ninja Turtles'' (or TMNT) started as a parody. In fact, the entire premise is built around the question of [[WhatHappenedToTheMouse what happened]] to the radioactive canister which gave Matt Murdock (aka {{ComicBook/Daredevil}}) his superpowers. The original comic was at first largely an [[AffectionateParody affectionate riff]] on Creator/FrankMillerís [[GratuitousNinja ninja-tastic]] reinvention of ''Daredevil'' in the 80s.[[note]]A joke maintained through 2012 variant covers that cheekily homage some of Millerís most iconic ''Daredevil'' poses.[[/note]]

Aspiring comic creators Kevin Eastman and Peter Laird, founders of "Mirage Studios" (so named because it didn't actually exist yet), came up with the concept one night after work, sketching their increasingly goofy ideas. The paradox of supposedly slow and cumbersome creatures being such stealthy, deadly warriors proved irresistible.

The resulting one-shot (ha) comic revolved around four titular turtles named after Renaissance artists - [[Creator/LeonardoDaVinci Leonardo]], [[Creator/RaphaelSanzio Raphael]], [[Creator/MichelangeloBuonarroti Michaelangelo]][[note]]Unintentionally misspelled; he would drop the extra A decades later[[/note]] and Donatello - battling the ninja crimelord Oroku Saki, better known as "[[RedBaron The Shredder]]", and his Foot Clan. The Turtles were trained by Master Splinter, a mutant rat, to avenge the murder of his owner Hamato Yoshi, a fugitive Foot member.

The original comic also recounts their origins through flashback. Once ordinary pet shop baby turtles, their aquarium was smashed by a metal canister which had flown from a van.[[note]]After hitting [[ComicBook/{{Daredevil}} a young man]] who pushed an old blind man out of the van's way.[[/note]] The baby turtles and the canister fell into the sewers where Splinter, still a regular rat, came across them. They were all covered in a strange chemical ooze from the canister, which led to them growing in size and intelligence and developing anthropomorphic appearances.

A surprise hit (credited to the bizarre name), later stories applied a FantasyKitchenSink approach, with time travel, robots, and aliens introduced within the first ten issues. The series became so popular in the indie comics scene that it spawned [[TeenageMutantSamuraiWombats a bunch of imitators]] and branched out into merchandising with T-shirts, figurines and the like. But the Turtles finally broke from CultClassic status to mainstream success when an action figure deal was struck with Creator/PlaymatesToys, and an animated series was created [[MerchandiseDriven to accompany the toyline.]] The show became one of the most popular animated series of all time, which in turn led to movies and every type of merchandise under the sun, turning TMNT into one of the biggest {{cash cow franchise}}s of the mid-eighties/early nineties.

The major incarnations of the franchise are as follows:

!Comic Books
* '''[[ComicBook/TeenageMutantNinjaTurtlesMirage The Mirage Comics]]''' (1984-1993, 2001-2010): Stories featuring the original incarnation of the turtles. These are notable for its semi-real time storytelling (stories written after 2001 featured the turtles in their thirties); its lack of a consistent RoguesGallery; and alternating between "throw-everything-at-the-wall-to-see-what-sticks" and "heavily focused" approaches to storytelling. This incarnation comprises Volumes 1, 2, and 4 of the ''Teenage Mutant Ninja Turtles'' comic book, two volumes of ''Tales of the TMNT'', and a multitude of one-shots and mini-series.
* '''''ComicBook/TeenageMutantNinjaTurtlesAdventures''''' (1988/1989-1995/1996): Midway through its run, the original cartoon spawned its own comic book, published by Franchise/ArchieComics. While it initially limited itself to adapting some of the cartoon stories, it eventually evolved into something as different from the cartoon as the cartoon was from the original comic book. This incarnation of the turtles is generally regarded favorably, with a notable contingent of fans clamoring for inclusion of its characters into future incarnations.
* '''[[ComicBook/TeenageMutantNinjaTurtlesMirage TMNT Vol. 3]]''' (1996-1999): Published by Image Comics, this series was the official continuation of the Mirage continuity, until it was [[CanonDiscontinuity subsequently ignored by Peter Laird]] upon the publication of Volume 4. Mostly remembered for mutilating three out of the four turtles, and for a plot featuring a three-way struggle for leadership of the Foot involving Raphael, who had taken on the Shredder identity after finding his armor; Pimiko, the original Shredder's daughter; and Lady Shredder, a ninja of unknown origin dressed in the familiar armor.
* '''The Dreamwave Comics''' (2003): The second cartoon had its own spinoff comic, published by Dreamwave Productions.
* '''[[ComicBook/TeenageMutantNinjaTurtlesIDW The IDW Comics]]''' (2011-): The first new incarnation of the Turtles following the purchase by Creator/{{Nickelodeon}} and published by Creator/IDWPublishing, it features elements from all previous incarnations before it, as well as heavily revised origins for the familiar characters.
** '''''ComicBook/BatmanTeenageMutantNinjaTurtles''''' (2015-2016): A {{Crossover}} between Franchise/{{Batman}} and the IDW version of the Turtles. Produced a sequel in 2017, this time seeing Batman and Robin travel to the Turtles' world.
* '''The Nick Comics''' (2012-2017): The third cartoon had its own spinoff also published by IDW. It was launched as ''Teenage Mutant Ninja Turtles: New Animated Adventures'' and later relaunched in 2015 as ''Amazing Adventures''. Also had a crossover with Batman, specifically the [[WesternAnimation/BatmanTheAnimatedSeries DCAU version]].

!TV Shows
* '''[[WesternAnimation/TeenageMutantNinjaTurtles1987 The first cartoon]]''' (1987-1996), with Fred Wolf at the helm: Resemblances to its source material are mostly superficial. The first cartoon featuring the turtles proved even more popular than the comics (and it definitely remains the best-known TMNT incarnation among the general public), thanks to the [[AdaptationDistillation distillation]][=/=]{{flanderization}} of the four turtles to easily identifiable character types; the [[CanonForeigner addition]] of villains Krang, Bebop and Rocksteady; the promotion of the Shredder from one-shot baddie to ArchEnemy; gleeful breaking of the fourth wall; the addition of food addiction (pizza) and a CatchPhrase ("Cowabunga!", although there were others), and a general LighterAndSofter comedic bent (for instance, Hamato Yoshi isn't murdered; he instead [[CompositeCharacter becomes]] Splinter). The series ended in 1996, after ten seasons, 194 episodes, and one retool nicknamed the "Red Sky" period by fans, which attempted to make the series more dramatic in the wake of more serious cartoons like ''WesternAnimation/XMen'' and ''WesternAnimation/BatmanTheAnimatedSeries''.
* '''''Anime/TeenageMutantNinjaTurtlesLegendOfTheSupermutants''''' (1996). An {{Anime}}. It is a two-episode OVA which adapts (very freely) the Turtles into Japanese anime format, although they're mainly [[MerchandiseDriven thinly-veiled ads]] for Takara's Japanese version of the ''Turtles'' toyline. Among the changes made, the turtles have the power to transform into ''"Super Turtles"'' for about three minutes (during which they look really manly), have an animal-themed armor each (like in ''Manga/SaintSeiya'') and can fuse together to form the ''"Saint Turtle"''. Besides that, the bad guys also have transforming powers, and Shredder turns into a Dragon. For further info, visit [[http://en.wikipedia.org/wiki/Teenage_Mutant_Ninja_Turtles:_Legend_of_the_Supermutants Wikipedia]] or just see [[http://www.youtube.com/watch?v=vGMfb60lc14&feature=related this video]].
* '''''Series/NinjaTurtlesTheNextMutation''''' (1997-1998): A live-action Saturday morning show by Creator/SabanEntertainment (guys behind ''Franchise/PowerRangers''), aired on Creator/FoxKids in 1998 shortly after the animated series ended. It lasted only one season before going belly-up. The new series added a new character, Venus de Milo, a female turtle with knowledge of the art of Shinobi (and playing the foil to the scientifically-minded Donatello). Many fans were [[FanonDiscontinuity antagonistic]] to the series, and Peter Laird was [[CreatorBacklash even]] [[BerserkButton more]] [[ExiledFromContinuity antagonistic]] to Venus. The characters crossed over into an episode of ''Series/PowerRangersInSpace''.
* '''[[WesternAnimation/TeenageMutantNinjaTurtles2003 The second cartoon]]''' (2003-2009): Mirage teamed up with [[Creator/FourKidsEntertainment 4Kids]] in order to produce this new cartoon, this time making sure it had [[TruerToTheText a closer resemblance]] to the comic book it was based on. Nicknamed TMNT 2k3, the series featured faithful adaptations of most of the comic book's stories, contained major [[{{Arc}} story arcs]], and straightened up the original patchwork narrative and made it more coherent. However, it also exercised its own creative license, introducing new friends and foes and perhaps most notably, playing with the Shredder's identity; by the end, multiple characters had taken the role. Surprisingly for a show produced by someone with [=4Kids=]' pedigree, it avoided several of the tropes associated with Saturday Morning cartoons, such as ThouShaltNotKill and StatusQuoIsGod. It ended in 2009, after six years, seven seasons, and two retools.
** '''''WesternAnimation/TurtlesForever''''', an animated movie crossing over this incarnation of the Turtles with that of the first cartoon, and acting as a celebration of the franchise's 25th anniversary. It also serves as a GrandFinale for both the '03 cartoon and the franchise's pre-Nickelodeon era.
* '''[[WesternAnimation/TeenageMutantNinjaTurtles2012 The third cartoon]]''' (2012-2017): A CG animated series that aired on Creator/{{Nickelodeon}}. The most {{Animesque}} take yet, full of MangaEffects and other Japanese visual humor. It's somewhat YoungerAndHipper - the Turtles act more like adolescents and several human characters have been aged down - but it still has dark moments. Narratively, the series draws heavily from the '87 cartoon and original live-action movies, but with long-running story arcs and other story elements inspired by other continuities.
* '''''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles''''' (2018-): The fourth cartoon and second Nickelodeon show. A 2D animated series that is set to be LighterAndSofter than the 2012 series. It mixes up the formula a little by making Raphael the leader instead of Leonardo and changing most of their signature main weapons.

* The Original Film Series
** '''''Film/TeenageMutantNinjaTurtles''''' (1990): The first movie combined events from the comic book with the cartoon's humor. It went on to be extremely popular, breaking records for an independent film and even though reviews weren't glowing, praise was given to Creator/JimHensonsCreatureShop for the costumes.
** '''''Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze''''': A follow-up movie, recasting April O'Neil and Casey Jones disappears. Criticisms of the mature content of the first film lead to some changes, with an overall more lighthearted tone and the Turtles avoid using their weapons to fight barehanded. The movie didn't do quite as well both financially and critically.
** '''''Film/TeenageMutantNinjaTurtlesIII''''': Revamped Turtle costumes resulted in reduced facial expressions, but more agile and swift action. The reduced budget and half-hearted promotion lead to a box office failure.
* '''WesternAnimation/{{TMNT}}''' (2007): The Turtles returned to the big screen with the 2007 release of the fully-CGI ''TMNT''. Made as a [[BroadStrokes tenuous continuation]] of the original movies, it received respectable reviews for the animation and character storylines, but was criticized for the main plot mysticism, some blurry character motivations (Leonardo in particular), and the [[OutOfFocus marginalization of half of the turtles]]. A sequel was hinted at, but never came about.
* '''''Film/TeenageMutantNinjaTurtles2014''''': A ContinuityReboot with Creator/MichaelBay's Platinum Dunes serving as the production company. Where the previous live-action films used people in animatronic suits to portray the Turtles, this one uses [[SerkisFolk CGI motion-capture]].
** '''''Film/TeenageMutantNinjaTurtlesOutOfTheShadows''''': 2016 sequel. Casey Jones, Bebop and Rocksteady make their debuts in this continuity. Has the same name as earlier videogame.

There is also a [[TabletopGame/TeenageMutantNinjaTurtlesAndOtherStrangeness role-playing gamebook]] released from 1985 to 2000 based on the Mirage comics and a [[Pinball/TeenageMutantNinjaTurtles pinball machine]] made by Creator/DataEast in 1991. The franchise is also the subject of a documentary film titled ''Turtle Power'', fan-made but distributed by Paramount.

TMNT remains a pop-culture phenomenon to this day. It inspired the entire TeenageMutantSamuraiWombats genre, and is a multimedia CashCowFranchise still beloved by many fans new and old.

!!The ''Teenage Mutant Ninja Turtles'' franchise has the following tropes:

%%* AbsurdlySpaciousSewer: Frequently played straight and averted.
* AccessoryWearingCartoonAnimal: The turtles walk around in everyday life clothes-less except for their ninja masks, belts, and generally some form of padding/supportive bandages on their joints/hands and feet.
* ActionFigureFileCard: Most of the toys have had them.
%%* ActionGirl:
%%** April O'Neil (depending on the incarnation).
%%** Karai.
%%** Ninjara in the Archie series.
* AdaptationDistillation: The 4Kids series and the fourth movie. The first movie successfully blends the original comics and cartoon into a coherent whole.
* AdaptationPersonalityChange:
** The characters are reinterpreted in every retelling, especially Michelangelo and Raphael. They typically fit the same archetype, but express it in different ways.
*** Michelangelo is usually the comic relief, but his approach to the role varies: In the Mirage Comics he's a laid-back NiceGuy, in the 1987 cartoon he's a surfer dude, in the film series he's a MotorMouth jokester, in the 2003 Cartoon he's a prankster and a [[TheGadfly Gadfly]], and in the 2012 Cartoon he's an outlandish {{Cloudcuckoolander}}.
*** Raphael is always the team rebel, but again his method of rebelling varies from incarnation to incarnation: In the Mirage comics he's a violent and sometimes unstable berserker, in the 1987 cartoon he's a wisecracking slacker, in the film series he's a brooding loner with a huge temper, in the 2003 cartoon he's gruff and standoffich and in the 2012 Cartoon he's a JerkWithAHeartOfGold with a HairTriggerTemper.
** All four Turtles were {{flanderized}} in the 1987 series, except for Leonardo who was only mildly flanderized. Donatello went from being intellectual to being a GadgeteerGenius, Michelangelo went from being mostly laidback to being a surfer dude obsessed with pizza, but most egregiously, Raphael went from being dark and violent to being snarky and constantly breaking the fourth wall.
* AdaptationSpeciesChange:
** Shredder was changed to a Utrom (an [[http://turtlepedia.wikia.com/wiki/Utroms alien]] in a robot suit) in the 2003 series.
** Splinter is always depicted as a mutant rat, but sometimes (like in the first and third cartoons), he started as a human. Other times (like in the Mirage comics, the 1990s film and the second cartoon), he started as a pet rat.
* AerithAndBob: When the turtles are addressed by their nicknames, Leo, Don/Donnie, and Mikey/Mike are all fairly common, and then you have Raphael's nickname, Raph.
%%* AlienAmongUs: The Utroms, initially.
%%* AliensAndMonsters
* AliensSpeakingEnglish: Played straight and averted in the same page of the original series.
* AllYourBaseAreBelongToUs: Several times, across incarnations more faithful to the original comic books, the attack on April's shop being the quintessential example.
* AlternateCompanyEquivalent: The Justice Force and its members, to varying degrees.
* AlternateContinuity: ''WesternAnimation/TurtlesForever'' revealed all TMNT media exist in its own universe. The 2012 cartoon followed this up by having the Turtles seeing the 1987 animation as an alternate universe!
%%* AlternateUniverse
* AnimalNemesis: The feud between Oroku Nagi and Hamato Yoshi is taken up by Nagi's brother and Yoshi's pet rat, and the Turtles themselves when they mutate.
* AnimalSuperheroes: And one example who got many follow-ups.
* AnotherDimension: A whole lot of them, most notably Dimension X in two continuities.
* TheAnticipator: Master Splinter usually plays this role in the show, as he is very wise and skilled. And a ninja, of course.
* ArtInitiatesLife: [[Creator/JackKirby Kirby's]] crystal allowed him to do this.
* TheArtifact: As the series became more kid-friendly it became fairly impossible to show Leonardo and Raphael slicing and dicing their non-robotic foes, as that would be bloody and gruesome. However, their weapons of katanas and sais are so iconic to them that they could never get rid of them. Thus more often than not, and particularly in the movies (which feature no robots) they'll just be seen fighting with their bare hands - their more effective weapons strapped to them untouched.
** ReimaginingTheArtifact: Which might be the reason why few of the foes (Foot Clan Ninjas e.g) were turned robotic midway in the [[WesternAnimation/TeenageMutantNinjaTurtles1987 animated series]] just to compensate for the lack thereof.
** The [[ArtifactTitle title itself]] became this as the Turtles continued to age in the comics well into their thirties.
* AscendedExtra: The Shredder ''died'' in the first ever Mirage issue, but he was promoted to the Turtles' arch-enemy in most other versions. The Foot tried bringing him back but it didn't stick.
* AsLongAsItSoundsForeign: Hamato Yoshi's surname (Hamato) doesn't exist in real Japanese. The Japanese dub of the 1987 cartoon [[DubNameChange called him]] "Yoshihama Takeshi" instead. Similarly, Oroku Saki's given name (Saki) is real but ''feminine''. Thus the Japanese dub and the ''Legend of the Supermutants'' OVA called him "Oroku Sawaki".
* AuthorAppeal: Creator/JackKirby and the cosmic themes of his work are often referenced in the various ''Teenage Mutant Ninja Turtles'' continuities, with at least one story in the Mirage Comics that was adapted as an episode for the 2003 series even featuring a thinly-veiled version of Jack Kirby. The adaptation was itself [[InMemoriam dedicated to his memory]].
* AvengingTheVillain: The basis of the Foot's vendetta against the turtles, after The Shredder's death in the comic books. In the 4Kids cartoon, this becomes Karai's motivation during the fourth season, after The Shredder (here her adoptive father) is exiled to an icy asteroid.
** Also the Shredder's motivation in the original comics. Oroku Nagi obviously wasn't a very nice guy to be [[IfICantHaveYou beating Tang Shen]] for choosing Hamato Yoshi over him, but Yoshi was [[DisproportionateRetribution probably going overboard by slaying Nagi in return]]. Oroku Saki's goal was to avenge his brother's death.
* AwesomeMcCoolname: Renaissance Artists and Japanese names and Irish names and Athletes and Violent Verbs and Notorious Conquerors, oh my! Wait; I think I missed some!
* BadassBookworm: Donatello, the one who builds machines.
* BadassPacifist: Donatello is known as the least violent of the four turtles and would rather use his intellect to solve conflict than his fighting skills. However, he is VERY competent in his fighting when it is needed.
* {{Badbutt}}: Nearly as iconic to the heroes as TotallyRadical is their application of UnusualEuphemism, at least in the 1987 series. "What the Shell" is one of the most uttered phrases in the 2003 series; at least as often as "Cowabunga" in the 1987 series.
* BeautyToBeast: April when turned into a fish mutant.
* BeneathTheEarth: The Turtles have lived in sewers and on subway platforms from time to time.
* BewareTheNiceOnes: Let's just say that you would want to stay on the good side of Michelangelo & Donatello.
* BigApplesauce: New York is the primary location for all incarnations.
* BigBad: Although the different incarnations may have their own individual Big Bads, The Shredder is the most traditional and consistent foe the turtles come across.
** Ironically, he was a VillainOfTheWeek in the original comic.
* BigBrotherInstinct: The turtles all fall under this trope at one time or another, in all the various incarnations. It has also applied to Casey and April.
* BladeBelowTheShoulder: [[CaptainObvious The Shredder]]
* BodyguardingABadass: Shredder's Elite Guard.
* CanonForeigner: Krang, Bebop, Rocksteady, Venus de Milo, Tatsu, Tokka, Rahzar and many more.
* CanonImmigrant:
** '''Archie Comics to Mirage''': Cudley the Cowlick
** '''4Kids Cartoon to Mirage''': Foot Mystics, The Battle Nexus, Hun and Bishop,Shredder's armor.
** '''First Film to Mirage''': Charles Pennington
** '''Any of them to IDW Comics''': If they've made a significant impact on any version of the Turtles, odds are they're in it.
* {{Catchphrase}}:
** '''Fred Wolf series:''' "Cowabunga!" "Turtle power!"
** '''Films:''' "God, I ''love'' being a ''turtle!!''
** '''4Kids series:''' "It's ninja time!" (''Fast Forward'' only) "Goongala!" (Casey) "None of you will leave here alive!" (The Shredder), "Oh, crud." (Hun).
** '''Nickelodeon series:''' "Booyakasha!" (Mikey)
* {{Cephalothorax}}: Krang, after being stripped of his body when he was banished from Dimension X. Shredder designed and built a humanoid exo-suit for him when they teamed up.
* CharacterSelectForcing: A few video games, be it due to combat (the original NintendoHard game, where Donatello was the only one with a decent range) or abilities (the Game Boy Advance version of ''Battle Nexus'' had some [[PlotCoupon crystals]] accessible only by certain turtles).
* CityOfAdventure: New York City, as well as Northampton, MA in the Mirage comics and 4Kids 'toon.
* ColorCodedCharacters: Since the original comic was in black and white, there wasn't much of this to begin with as each turtle was identified by their WeaponOfChoice. Even the special colored issues had the bandana masks they wear all red. The original cartoon gave the turtles different color bandannas (which have since been used in every successive incarnation) and the action figures, different skin colors (ignored until the 2003 cartoon).
** The Archie comic series {{Lampshade}}d this with a TruthInTelevision flashback story about the pre-teenaged Turtles all wearing red headbands and Splinter having difficulty telling them apart until they decide on color coding their masks a la DonaldDuck's nephews. This crosses into OnlySixFaces.
** The newspaper strip, as it was also in black and white, took a page from the 1987 cartoon and the turtles here have their initials on their belts instead.
* ConservationOfNinjutsu: [[SubvertedTrope SUBVERTED of all things!]] In the First Movie and the 4Kids series, The Foot have got alot of mileage out of [[ZergRush sending wave after wave of]] {{Mooks}} after the Turtles (Raphael in the 1990 movie, and Leonardo in the Comics and 4Kids series) and [[NoHoldsBarredBeatdown whooping their asses.]]
* ConspicuousTrenchcoat: The turtles' way of staying hidden. On the other hand this ''IS'' New York, where nobody looks at anybody else, so, fair enough.
* CosmicKeystone: [[spoiler: The dimension of the original Mirage Comics for the Multiverse]] in "Turtles Forever".
* {{Crossover}}:
** Most important is Miyamoto Usagi of ''ComicBook/UsagiYojimbo'', who has appeared in the Mirage comics, the Fred Wolf cartoon and the 4Kids cartoon; the Turtles have also made the occasional appearance in the ''Usagi Yojimbo'' comic books.
** And ''WesternAnimation/TurtlesForever'', a crossover between the 4Kids and Fred Wolf shows. [[spoiler: Did we mention the Mirage comics?]]
** ''WesternAnimation/CartoonAllStarsToTheRescue'' features 1987 Mikey among [[MassiveMultiplayerCrossover many other toons]].
** ''The Next Mutation'' guest starred in the ''Series/PowerRangersInSpace'' episode "Shell Shocked".[[note]]Retroactively, this did get ''Franchise/PowerRangers'' to beat its father ''Franchise/SuperSentai'' to the punch at an IntercontinuityCrossover with an eleven-year gap. For the record, the ''Sentai'' crosover was ''Series/KamenRiderDecade''/''Series/SamuraiSentaiShinkenger''... and ''Shinkenger'' is as just as well loved as ''In Space'', like ''Decade'' is as hotly contested as ''The Next Mutation'' (albeit for different reasons).[[/note]]
** The VideoGame/RavingRabbids[[note]]Back when they were still part of -- and outright hijacked -- the ''Franchise/{{Rayman}}'' series[[/note]] in the ''Smash-Up'' video game. They immediately became new [[TheScrappy Scrappies]] for the TMNT fandom.
** There was a crossover with ''Planet Racers'', another comic created by Peter Laird, in an episode of the 2003 series.
** Because the brainchild of ''WesternAnimation/WildWestCowboysOfMooMesa'' did some of the issues of the original comic series, Cowlorado Kid, Moo Montana and Dakota Dude appeared in some of the ''Tales of the TMNT'' issues and made non-speaking roles in an episode in the 2003 cartoon.
** Due to IDW owning the rights for TMNT comics as of 2011, the Turtles have also become recurring characters in IDW's yearly {{Massive Multiplayer|Crossover}} {{Cross Through}}s, having appeared in 2012's ''Infestation 2'' against the Franchise/CthulhuMythos and in 2014's ''Series/TheXFiles: Conspiracy''. No, the Turtles don't get to meet Mulder and Scully (though Mulder does get a one-panel cameo), but they do tangle up with Mulder's buddies Series/TheLoneGunmen and the vampires from the ''X-Files'' episode "[[Recap/TheXFilesS05E12BadBlood Bad Blood]]."
** Since it's now a Creator/{{Nickelodeon}} property, the TMNT have a few appearances in [[http://www.nick.com/ninja-turtles/games/ online games with other Nick stars, both cartoon and live-action.]] Funnily enough, they once again crossover with the Power Rangers and the Rabbids.
** The original comic series also crossed over with ComicBook/CerebusTheAardvark; the most recent IDW version crossed over with the goddam Franchise/{{Batman}}.
* CrouchingMoronHiddenBadass: Michelangelo, in every incarnation, is the usually the goofball/slacker/fun-loving guy of the group, but when it comes down to having an actual fight....you don't really wanna be on the receiving end.
* CutLexLuthorACheck: Repeatedly subverted by Baxter Stockman. In the Mirage comics, after making a large legitimate fortune with his Mouser robots, he then proceeds to use them to commit terrorism for kicks. In the 1980s cartoon, he tried using them legitimately but was rejected by every pest control company in town. In the 4Kids cartoon, he makes a huge legitimate fortune with them, and then starts using them to rob banks simply because he's a greedy bastard.
* CycleOfRevenge: One of the most important themes in the original Mirage books.
* DamselInDistress: April O'Neil always, though taken UpToEleven in the first cartoon where the turtles [[RuleOfFunny can recognize her by her]] [[BoundAndGagged "mmphing"]].
* DeadpanSnarker: Being teenagers, all four of them usually do it at some point, but Raphael is the one that's known for it the most. Master Splinter also has his dry humor moments.
* DistaffCounterpart: Venus de Milo, who fit in as an ActionGirl and TheChick in ''Next Mutation'' since it didn't even feature April as a character.
* DistinctiveAppearances: The original comics run had the turtles effectively defined by their WeaponOfChoice and nothing else, being they were in black and white. Even early color issues had them all with red bandannas, only after a few years did they get their distinctive colors. Various incarnations continue to play with tricks to make them stand out from each other: ''Series/NinjaTurtlesTheNextMutation'' played with the styling of the belts and bandannas (with Michelangelo having frayed edges and Donatello having a full cap), ''WesternAnimation/TeenageMutantNinjaTurtles2003'' gave them all slightly different green skin pigments and ''WesternAnimation/TeenageMutantNinjaTurtles2012'' did some more subtle things like Donatello's chipped tooth.
* DittoAliens: The Utroms; Triceratons.
* DivergentCharacterEvolution: In Issue #1, the turtles were barely distinguishable from each other, each with a similar personality, though Leonardo and Raphael show a few hints of some, but the turtles were defined by the fact they're a parody of Creator/FrankMiller style writing. Later installments started adding personality to all four of the turtles, with the adaptations adding colored bandanas to help recognize them without their weapons. The new show takes it even further by giving the Turtles their own body-types, allowing you to distinguish them from each other ''without'' the weapons ''or'' bandanas.
* DualWielding: Three of the four turtles use their weapons in pairs, with Donny being the odd man out. Though since his weapon is a bo staff, it's justified (although his original action figure did come with a pair of bo).
* EarlyInstallmentWeirdness: Splinter and the Turtles ''not'' treating each other as father and sons respectively in older works feels pretty alien now, given that pretty much every major fiction for the past few decades has the five explicitly considering each other family even though they're not blood. Lampshaded in ''Turtles Forever'', where the '87 Turtles are surprised to see that their 2003 counterparts explicitly call Splinter "father" and he calls them "my sons".
* ElaborateUndergroundBase: The turtles' lair is usually one of these.
* EmeraldPower
* TheEndOfTheWorldAsWeKnowIt: TMNT just wouldn't be the same if this trope were non-existent.
* EveryJapaneseSwordIsAKatana: Occurs with every ninja-to in the series.
** Except for Leo's swords in the 4Kids cartoon (even though everyone still calls them katana), or the 2007 CGI movie, one might point out...
*** In the live-action movies Leo is obviously wielding ninjato.
*** The RPG makes a point of defining Leo's swords as a daisho, a set of katana and wakizashi.
* EvilPowerVacuum: Occurs after the Shredder is defeated at the end of the ''Return to New York'' arc in the Mirage comic books and in the second cartoon.
* ExposedExtraterrestrials: In all of their incarnations, the turtles are seldom seen wearing anything besides their bandanas and weapons, unless it's part of a disguise.
* ExpositoryThemeTune: "Splinter taught them to be ninja teens!" "He's a radical rat!"
* {{Expy}}: The Ninja Turtles were originally a parody of ''ComicBook/{{Daredevil}}''. Splinter was a stand-in for Daredevil's mentor Stick, while the Foot Clan was a parody of the Hand, a secret group of ninjas fought by Daredevil.
%%* FacelessGoons: The Foot Clan.
* FantasyKitchenSink: Prevalent through all incarnations of the series, to varying degrees. There's also quite a bit of overlap between the disparate fantastic elements.
* FarEastAsianTerrorists: The Foot Clan engages in terrorism at several points in the franchise. [[Film/TeenageMutantNinjaTurtles2014 The 2014 movie]] portrays them as WesternTerrorists, however.
* FightingWithChucks: Michaelangelo uses chucks as his primary weapon.
* FinalExchange: In the "hidden episodes", when a spirit form of Hamato Yoshi defeats the demon form of the Shredder.
--> '''Shredder''': I will fight you to the last breath!
--> '''Yoshi''': Your dragon form ''was'' your last breath. [performs OneHitKO]
* FishPeople: Mona Lisa from the original series' "Raphael Meets His Match"; the fish people from "Sons of the Silent Age."
* FiveManBand: The Turtles and their allies.
** TheLeader: Leonardo
** TheLancer: Raphael
** TheSmartGuy: Donatello
** TheBigGuy: Michelangelo
** TheChick: April
** TheSixthRanger: Casey
** TheMentor: Splinter
* ForHalloweenIAmGoingAsMyself: The turtles are wont to do this.
* ForTheEvulz: In the original comics, April asks Baxter Stockman why he is using his Mousers to hold the city for ransom when he has already made a vast fortune with them. He answers that ''it's fun!''
* TheFuture: Plays a significant part in several incarnations, particularly in the Mirage and Archie comics, which had several stories starring future versions of the turtles, and the second cartoon, whose setting for the entire sixth season was the year 2105.
%%* GenericanEmpire: The Federation.
* GeniusBruiser: Leatherhead in the 2k3 incarnation.
* GenreSavvy: Michelangelo with his vast knowledge of pop culture usually is the one to reference how something they're dealing with is similar to a movie, tv show, or video game he knows about.
* GettingCrapPastTheRadar: In the episode "Fallen Angel" in the 4kids series, Leo (in disguise) asks Raphael "What is the deal with humans and clothes?" Raph's response? "You ever see a human in his skivies? Trust me, It's not a pretty sight." So what does Raphael do with his free time?
* GoodRepublicEvilEmpire: Averted all to hell in the 4Kids series. Both TheFederation (humanoids) and [[PeoplesRepublicOfTyranny The Republic]] (Triceratons) are pretty nasty.
* GovernmentAgencyOfFiction: D.A.R.P.A. in the Mirage comic books and its animated counterpart, the Earth Protection Force.
* GrandFinale: ''WesternAnimation/TurtlesForever''.
* HaveYouComeToGloat: Happened in the comic. The turtles were being held prison by a crazed whaler who was essentially a Japanese [[Literature/MobyDick Captain Ahab]]. When his first mate visits them in the brig, they start cursing at him and one of them shouts, "Come to gloat?" Subverted in that the whaler has actually come down to free them.
* HeroWithBadPublicity: In the 80's cartoon, the turtles were once framed for a crime they didn't commit and nobody believes them, not even April and they have to prove themselves innocent.
** Whenever the 2003 turtles are seen by humans, said humans usually end up running away screaming, notable occasions are when Raph returned a lady's purse only to be told to stay away from her and Mikey's failed attempts at being a hero as he's either given no thanks or mistaken for the perpetrator. In Season 4, Bishop creates a fake alien invasion to trick the President into thinking his organization doesn't deserve to lose all their funding, and afterwards, a news report depicts the turtles as malicious aliens.
** In the 2007 movie, Nightwatcher [[spoiler: AKA Raph]] was either feared or despised for fighting crime and when Leo discovers his secret identity, he gets called out for risking the safety of his keeping his family's existence a secret.
* HighlyVisibleNinja: The turtles, of course. There are other ninjas present too (some of the Shredder's minions for an example) who stand out from the crowd.
** In the Turtles' defense, it's not like they ''chose'' to look so recognizable, what with not even being humans to begin with. In fact, in many versions, that's the very reason Splinter trained them to begin with: so they could make up for their appearance and avoid persecution from humans by being stealthy and constantly hiding in the shadow.
* HonorBeforeReason: A trait seen in most incarnations of Leonardo. It goes both ways though- either he is commended or, if something goes horribly wrong, grievously injured.
** Also Karai, whose loyalty to the Shredder conflicts with her strong sense of honorable behavior.
* HumanAliens: A large part of the Federation, including most of its army.
* IfICantHaveYou: The reason why Oroku Nagi beats on Tang Shen in the original comics, and why Oroku Saki and Yukio Mashimi kill her in the movie and the 4Kids cartoon, respectively.
%%* InterdimensionalTravelDevice
* IntraFranchiseCrossover:
** ''WesternAnimation/TurtlesForever'' is a textbook example with the Turtles from the 2003 animated series meeting up with the Turtles from the 1987 animated series, the two versions of the Turtles exist in alternate dimensions and meet each other when messing with interdimensional travel, in the end both versions meet the original Turtles from the 1984 comic books, they're presented as the prime Turtles, and erasing their existence would do the same to all the other versions.
** Also, a computer screen shows the Multiverse, with the many dimensions populated by other versions of the Turtles like the 2007 CGI movie, the live-action movies from the 90s, and even the bizarre two-episode anime, however, missing from the screen are some {{Old Shame}}s like the Live-Action Series and the Rock Musical, but even the incredibly weird two-part anime is there.
** The 2012 animated series did it again, with an episode crossing over with the 1987 cartoon with a plot that feels ripped off from Turtles Forever, again having the original 1984 Turtles at the end, and since the 1987 cartoon was hand-drawn but the 2012 was CGI, the episode uses ArtShift, alternating between hand-drawn animation and CGI depending on which universe the scene takes place, and converting the look of the Turtles in the process, for some reason, 1987 and 2012 Donatello stay in their original 2D and 3D forms when they enter the 1984 comic universe, they even have color when the whole comic-book world is black and white.
* IrislessEyeMaskOfMystery: They originally had Irisless eyemasks to simulate GlowingEyesOfDoom, without actually making their eyes glow. When they gave the turtles visible irises? They looked cute instead, regardless of how menacing they make their faces look. The only other media to retain this look from the comics was the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 cartoon]] (although the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 show]] uses them whenever [[LetsGetDangerous things get serious]]).
* LegacyCharacter: Several people have taken on the Shredder's mantle after besides Oroku Saki, with Karai being the most popular one.
%%* LicensedGame: So very many.
* LicensedPinballTable: Released by Creator/DataEast in 1991, and based on the first cartoon and movie. [[Pinball/TeenageMutantNinjaTurtles Click here for details.]]
%%* LiveActionAdaptation
* LighterAndSofter: Fans of either cartoon series who then read the original comic book rarely expect its ''much'' darker tone, and may be shocked that the turtles actually kill people.
** And often ''heartbroken'' by the issue where [[spoiler: Master Splinter dies]]. Hell, even many fans who started with the comics find it a TearJerker.
* LongRunners: 30+ years and still going strong.
* LostInImitation: The turtles' tails and red bandannas.
* LoveTriangle: Hamato Yoshi, Tang Shen, and Oroku Nagi (or, alternatively, Oroku Saki or Yukio Mashimi, depending on the incarnation) form one of these. Also, Stainless Steve Steel, Dr. Dome, and Battling Bernice.
** The 2012 series is clearly building up to one between Donnie, April, and Casey.
%%* {{Masquerade}}
* MechaMooks: Several, most notably The Foot Soldiers in the first animated series.
* MediumAwareness: A regular feature of the first cartoon.
%%* EnvironmentSpecificActionFigure
* MerchandiseDriven: ''TMNT'' didn't start this way, but it moved in this direction once the toy line became hugely successful. Ironically, it was originally intended as a slightly DarkerAndEdgier ''parody'' of merchandise-driven cartoon series and comics. Then the creators realized it was becoming one, and just rolled with it, and now the series has become [[TeenageMutantSamuraiWombat the archetype for such franchises]]. It's even had a parody or two.
* MistakenForAliens: Occurs to the turtles a lot, once the existence of aliens is actually made known to the general population.
* MobileSuitHuman: The alien Utroms used robotic exoskeletons to hide among humans while stranded on Earth. Also used by the Kraang in the 2012 cartoon.
* MonochromaticEyes: Several incarnations of the turtles--but only when they wear their masks.
* {{Mooks}}: Of all stripes, the most common and consistent being the Foot Ninja.
* MorallyAmbiguousDoctorate: Dr. Dome, Dr. Malignus.
* TheMultiverse: Turtles Forever, a crossover between the 80s and 2k3 series, introduces the idea that ''all'' incarnations of the franchise exist in different dimensions. Destroy the core, that being the Mirage universe, and all will cease to exist.
** This may have been hinted at as early as the Battle Nexus arc, when the 2k3 characters are said to come from Dimension 3rd Earth, implying that there are at least 2 other versions. The 2012 Nickelodeon series confirms the multiverse by having the 2012 characters observe and interact with the 87 cast as well.
* {{Nanomachines}}: Used by Baxter Stockman in the Mirage comics during a murder attempt on April, and by the turtles in order to foil said attempt. Also used in the 4Kids animated series to form Nano, a sentient nanomachine colony.
* NebulousEvilOrganisation: The Foot Clan in some incarnations.
* NinjaBrat: The turtles are this in any flashback to their childhoods.
* NinjaPirateZombieRobot: Do we really need to explain this one? Besides the obvious, there are also robot ninjas.
%%* NonLethalWarfare: Depending on the incarnation.
* NonMammalMammaries: Venus de Milo has these.
* NoTranshumanismAllowed: The 4Kids series has a cyborg and an infomorph, but only villains are non-organic, for the most part. Honeycutt, an [[BrainUploading uploaded man]], is a subversion.
** In the 2010 series, it's hard to find a good guy ''other'' than the turtles and Splinter who has become a mutant, or a bad guy who stays human long.
%%* OfficialCosplayGear
%%* {{Old Superhero}}es: The original Justice Force.
%%* OppositesAttract: April and Casey.
%%* PapaWolf: Splinter.
* PopularSayingBut: Wise man say: Forgiveness is divine, but never pay full price for late pizza.
* PortalPool: The main method used to enter the Battle Nexus.
* PosthumousCharacter: Hamato Yoshi, Tang Shen, Oroku Nagi/Yukio Mashimi, and Professor Obligado.
* PoweredArmor: The future versions of the turtles wore these for an arc in the Archie comic; the same armor also showed up in an episode of the Fred Wolf 'toon. Also, villains Baxter Stockman and Darius Dun have worn these on occasion.
* PowerUpgradingDeformation: The usual effects of the Ooze are to make creatures smarter or tougher but also uglier {{Half Human Hybrid}}s.
* PragmaticAdaptation: The original movie and 4Kids cartoon.
* TheProfessor: Tons: Donatello (when he's not a TeenGenius), Professor Honeycutt, Leatherhead, Glurin, Professor Obligado, Dr. Chaplin... Ironically, the one guy actually called "The Professor", from the 4Kids cartoon, isn't an example.
* RaceLift: Baxter Stockman in the Fred Wolf cartoon and one-shot villain Skonk in the 4Kids cartoon, who were both changed from African Americans to Caucasians.
** April was AmbiguouslyBrown in the Mirage comic, but in the cartoon and most subsequent adaptations has become [[FacialProfiling a stereotypically Irish-looking woman with pale skin and red hair]].
** Bebop was African American in the original cartoon prior to his mutation, but a transforming action figure that switched from human to mutant forms depicted him as being white.
* RatKing: The Rat King tends to be depicted as having control over rats in some adaptations. In [[WesternAnimation/TeenageMutantNinjaTurtles1987 the first cartoon]], he is initially capable of doing so via a flute ala ''Literature/ThePiedPiperOfHamelin'', and in later episodes he can do it psychically. In [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2003]] and [[WesternAnimation/TeenageMutantNinjaTurtles2012 the 2012]] cartoons, he is able to do so mentally from the start.
* RedOniBlueOni: Raphael and Leonardo. Heck, even their headbands' colors match.
** Also, Michelangelo and Donatello, though to a lesser extent.
* RelationshipUpgrade: Occurs with April and Casey at several points in each incarnation.
* RockMonster: The Rock Warriors from Dimension X.
%%* RoofHopping
%%* RooftopConfrontation
* RubberMan: Joey Lastic of the Justice Force.
* SecondaryAdaptation:
** All the VideoGame/TeenageMutantNinjaTurtles video games are based on the Film or Cartoons, which themselves were based on the Comic.
** The films also take influence from the cartoon, making video games based on films a tertiary adaption, in a sense.
* SecretPublicIdentity: Ananda of the Justice Force; her mother, Battling Bernice; "Stainless" Steve Steel, and Joey Lastic.
* SewerGator: Leatherhead in most incarnations is an alligator who ended up in the city sewers and was exposed to the same mutagen as the turtles, resulting in him growing into LizardFolk and becoming sapient.
* ShoutOut: Their origin story in the original comics suggests the radioactive waste that mutated them is the same stuff that gave Daredevil his powers.
--> '''Splinter:''' At the last moment a young man leaped at the blind man and knocked him out of the truck's way ... a metal canister bounced out of the back of the truck and struck the young man near his eyes ... the strange canister bounced ... striking and smashing a glass jar which held four small turtles ... you four as infants!!!
%%* SiblingTeam
* SixthRanger: Usually April and/or Casey act as the brothers' fifth teammate; the Nick cartoon even subtly hangs a lampshade on April by having her wear a #5 sports jersey. In ''Next Mutation'', it was Venus de Milo.
* SlimeSnailsAndMutantTails: All the radioactive waste, mutant friends and foes, ooze etc.
* StealthHiBye: These guys could give Batman a run for his money at this.
* StockNinjaWeaponry: Frequently used by the turtles.
%%* StoryArc
* SuperStrength: Although it's never really touched upon except in a few instances, all four of the turtles are obviously stronger than most humans. Though when they start battling other mutants, technology and aliens it starts to not matter as much.
** Brought up a little more in an episode of the 1987 show, where Michaelangelo managed to briefly become human, but lost the ability to do most of his ninja tricks, more so than can be explained by being used to a different body.
%%* TagalongReporter: April O'Neil.
%%* TheSyndicate: The Foot Clan.
* TeenageMutantSamuraiWombats: Possibly the TropeCodifier.
* TeleportersAndTransporters: The Utroms' Transmat and Honeycutt's Teleportal. Cudley the Cowlick can do this naturally.
* ThemeNaming: All the turtles are named after Italian Renaissance artists. Bebop and Rocksteady are musical references. The Mutant Frogs are named after great warlords, and more.
* ThemeTuneRollCall: The one from the Fred Wolf series is the [[EarWorm best-known]], but the fourth season of the 4Kids series also has one.
* TheyDo: Casey and April in various media.
* TheyWouldCutYouUp
* ThirdOptionAdaptation: Splinter defeating Shredder in TheMovie.
* ThisIsGonnaSuck: The phrase used, most often by Raphael and Hun, is "Ah, crud."
* ThoseTwoBadGuys: Bebop and Rocksteady.
* ThouShaltNotKill: Used or averted, depending on the incarnation. The Fred Wolf animated series and its spin-off comic book use it; the original comic book, movies, and 4Kids animated series generally don't.
* TimePolice: Renet and Lord Simultaneous, who form part of a larger, if unseen, organization.
* TitleThemeTune: All of the western cartoon themes.
* TookALevelInBadAss: Bebop and Rocksteady in the IDW series. Although still idiots, they're now ''competent'' idiots, and pose a legitimate threat to the turtles. [[spoiler: In issue 44 they apparently ''kill'' Donatello.]]
* TotallyRadical: They live in [[BigApplesauce New York City]], but sound like a bunch of {{surfer|Dude}}s from [[UsefulNotes/AmericanAccents Southern California]]. (''Especially'' Michelangelo, and sometimes--depending on the continuity--excepting Raphael.)
*** It's ''usually'' only Mikey. Raph has a Brooklyn accent in the films too, and even in the Fred Wolf cartoon series Mikey was the only one to sound like a surfer dude, though they all used "Cowabunga."
* ToxicWasteCanDoAnything:
** If it's not explicitly presented as MutagenicGoo, the 'ooze' that created the title characters is this: a garbage chemical mix on its way to be disposed that grants four turtle babies and a rat bipedal humanoid forms, sapience (at least in the Turtles' case; sometimes Splinter is suggested to have been far smarter than the average rat before mutation), enough physical gifts to be trained as master martial artists/weapon wielders, and in Donatello's case, near-genius level intelligence with mechanical devices. Not bad for a bunch of waste chemicals.[[note]]And if you follow the meta-joke in their origin, it also empowered Daredevil, or woke his powers up according to some sources, though Matt Murdock suffered the cost of losing his sight.[[/note]]
** This fact makes a scene in the second live action film, ''The Secret Of The Ooze'', strangely more poignant. Donatello is upset when he finds out the titular ooze's creation was just a mistake and that he had felt like that the truth would mean he and his family were 'special'. For being the smart one, he doesn't seem to realize that the fact that a bunch of chemical garbage instead of a purposely designed product made him and his family what they are makes them very special indeed.
* TrademarkFavoriteFood: Pizza, at least in the Fred Wolf cartoon and movies.
** Though not necessarily true in the 4Kids animated series, it's been alluded to several times. Especially related to Mikey.
*** Outside of the Fred Wolf 'toon and movies, every turtle actually has their own favorite food. Leo's is sushi (or some other appropriately Japanese food), Raphael's is cereal, Donatello's is hamburger, and Mikey's is, naturally, pizza. This just doesn't reach TrademarkFavoriteFood levels and is usually barely mentioned, though in the GBA classic beat 'em up style TMNT movie game, each Turtle is healed by their favorite foods.
*** The fourth film gives Splinter one: Cake.
* TrueCompanions: The turtles + Casey and April form this unit, most notably in the movies and 4Kids cartoon.
* TurtlePower: The TropeNamer, [[CaptainObvious given the main characters]].
* UncannyFamilyResemblance: Ananda to Battling Bernice (daughter/mother)
* VagueAge:
** Occurs with several of the characters throughout incarnations, due to a lack of specific dates or starting ages. [[CaptainObvious The mutant ninja turtles are nearly always teenagers.]] Nearly all fans seem to agree (based on the average confirmed starting ages per post-comic continuity, if given any) that the four are fifteen, and gain a half-year per season or age in real-time (week-for-week).
** The Mirage comics were notable in averting it. The Turtles started out as fifteen ([[WiseBeyondTheirYears but acted much older]]) and continued to age pretty much in real time until the present day where they're currently in their 40's and Splinter has since died of old age.
** In the 2007 film the Turtles' ages are never specified, however they are supposed to be roughly 19 years old, so in this instance they did not age in real-time since the films in the 90's.
%%* VitriolicBestBuds: Casey and Raph tend towards this in most continuities.
* VideoGameAdaptation: Several games were made for TMNT starting with the NES / Famicom game and ending with the latest Arcade game dated 2009!
* VolleyingInsults: Done playfully between Casey and Raph in the Mirage comics, in a scene which was later adapted for the first movie and 4Kids cartoon.
** The first movie even turned it into a game with actual rules. Each insult had to start with the next letter of the alphabet from the previous one.
* WebComics: Online fan comic/manga "MNT Gaiden"
* {{Weirdness Magnet}}s: Aliens, demons, robots, ninjas, Atlanteans, monsters, corporate executives, crazy people, members of near-extinct races and species, spirits, ghosts, psychics, alive machines, time traveling miscreants, [[AIIsACrapshoot evil AI]], gangs, anthropomorphic animals, and many, many mutants.
* WesternSamurai: While technically being a ninja, Leonardo is a warrior born and raised in the sewers of New York City with katanas as his WeaponOfChoice and who follows the way of bushido and values honor.
* WidgetSeries: Seriously, the only reason this franchise makes any sense is because we're so used to it.
