Question: Did the Teenage Mutant Ninja Turtles ever help any other superheros?

Teenage Mutant Ninja Turtles




The Teenage Mutant Ninja Turtles (often shortened to TMNT or Ninja Turtles) are four fictional teenaged anthropomorphic turtles named after Italian artists of the Renaissance. They were trained by their anthropomorphic rat sensei in the art of ninjutsu. From their home in the sewers of New York City, they battle petty criminals, evil overlords, mutated creatures, and alien invaders while attempting to remain hidden from society. They were created by Kevin Eastman and Peter Laird.
The characters originated in comic books published by Mirage Studios and expanded into cartoon series, films, video games, toys, and other merchandise.[2] During the peak of the franchise's popularity in the late 1980s and early 1990s, it gained worldwide success and fame.
History

The Teenage Mutant Ninja Turtles first appeared in an American comic book published by Mirage Studios in 1984 in Dover, New Hampshire. The concept arose from a humorous drawing sketched out by Eastman during a casual evening of brainstorming and bad television with Laird.[3] Using money from a tax refund, together with a loan from Eastman’s uncle, the young artists self-published a single-issue comic intended to parody four of the most popular comics of the early 1980s: Marvel Comics’ Daredevil and New Mutants, Dave Sim’s Cerebus, and Frank Miller’s Ronin.[4] The TMNT comic book series has been published in various incarnations by various comic book companies since 1984.
The Turtles started their rise to mainstream success when a licensing agent, Mark Freedman, sought out Eastman and Laird to propose wider merchandising opportunities for the franchise. In 1986, Dark Horse Miniatures produced a set of 15-mm (approximately 0.6 inch) lead figurines. In January 1987, Eastman and Laird visited the offices of Playmates Toys, a small California toy company that wanted to expand into the action-figure market. Development was undertaken by a creative team of companies and individuals: Jerry Sachs, advertising agent of Sachs-Finley Agency, brought together the animators at Murakami-Wolf-Swenson headed by Fred Wolf. Wolf and his team combined concepts and ideas with the Playmates marketing crew, headed by Karl Aaronian, vice president (VP) of sales Richard Sallis, and VP of Playmates Bill Carlson.[5]
Aaronian brought on several designers and concepteur and writer John C. Schulte, and worked out the simple backstory that would live on toy packaging for the entire run of the product and show.[5] Sachs called the high concept pitch "Green Against Brick". The sense of humor was honed with the collaboration of the Murakami-Wolf-Swenson animation firm's writers. Playmates and their team essentially served as associate producers and contributing writers to the miniseries that was first launched to sell-in the toy action figures. Phrases like "Heroes in a half shell" and many of the comical catch phrases and battle cries ("Turtle power!") came from the writing and conceptualization of this creative team. As the series developed, veteran writer Jack Mendelsohn came on board as both a story editor and scriptwriter. David Wise, Michael Charles Hill, and Michael Reaves wrote most of the scripts.
The miniseries was repeated three times before it found an audience. Once the product started selling, the show got syndicated and picked up and backed by Group W, which funded the next round of animation. The show then went network, on CBS. Accompanied by the popular Teenage Mutant Ninja Turtles 1987 TV series, and the subsequent action figure line, Teenage Mutant Ninja Turtles became a mainstream success. At the height of the frenzy, in the late 1980s and early 1990s, the Turtles' likenesses could be found on a wide range of children's merchandise, from Pez dispensers to skateboards, breakfast cereal, video games, school supplies, linens, towels, cameras, and toy shaving kits.
While the animated TV series, which lasted for 10 seasons until 1996, was more light-hearted, the comic-book series continued in a much darker and grittier tone. In 1990, a live-action feature film was released, with the Turtles and Splinter being portrayed by actors in partially animatronic suits created by Jim Henson's Creature Shop. The film became one of the most successful independent films and spawned two sequels, as well as inspiring a three-dimensional animated film set in the same continuity, which was released in 2007 under the title TMNT. After the end of the cartoon series, a live-action series in the vein of the films was created in 1997 in conjunction with Saban Entertainment. The series was called Ninja Turtles: The Next Mutation and introduced a fifth, female turtle called Venus de Milo. However, the series was largely unsuccessful and was canceled after one season.
The property lay dormant until 2003, when a new animated TV series also entitled Teenage Mutant Ninja Turtles began to air on Fox Box (4Kids TV). The series storyline stuck much closer to the original Mirage comic book series, but was still less violent. It lasted for seven seasons and 156 episodes, ending in February 2009.
On October 21, 2009, it was announced that cable channel Nickelodeon (a subsidiary of Viacom) had purchased all of Mirage's rights to the Teenage Mutant Ninja Turtles property. Mirage retains the rights to publish 18 issues a year, though the future involvement of Mirage with the Turtles and the future of Mirage Studios itself is unknown.[6] Nickelodeon has developed a new CGI-animated TMNT television series and partnered with fellow Viacom company Paramount Pictures to bring a new TMNT movie to theaters. The TV show premiered on Nickelodeon on September 29, 2012.[7]  The live-action film, produced by Platinum Dunes, Nickelodeon Movies, and Paramount Pictures, directed by Jonathan Liebesman, and produced by Michael Bay, was released on August 8, 2014.[8]
Main characters

Leonardo (Leo)–The tactical, courageous leader and devoted student of his sensei, Leonardo wears a blue mask and wields two swords. As the most conscientious of the four, he often bears the burden of responsibility for his brothers, which commonly leads to conflict with Raphael. Leonardo was named after the Italian polymath, painter, engineer, inventor, writer, anatomist, and sculptor, Leonardo da Vinci.
Michelangelo (Mikey or Mike)– The most stereotypical teenager of the team, Michelangelo is a free-spirited, relaxed, goofy and jokester, known for his love of pizza. Michelangelo wears an orange mask and wields a pair of nunchaku. He provides the comic relief, though he still has an adventurous side. The least mature of the four Turtles, he shows characteristics of a "surfer" type and is often depicted with a Southern Californian accent. He is named after the Italian Renaissance painter, sculptor, architect, poet, and engineer, Michelangelo. His name was originally misspelled "Michaelangelo" by Peter Laird and Kevin Eastman.[9]
Donatello (Donnie or Don)–The scientist, inventor, engineer, and technological genius, Donatello wears a purple mask and wields a bo staff. Donatello is perhaps the least violent turtle, preferring to use his knowledge to solve conflicts, but never hesitates to defend his brothers. He is named after the early Renaissance Italian artist and sculptor from Florence, Donatello.
Raphael (Raph)–The team's bad boy, Raphael wears a red mask and wields a pair of sai. He has an aggressive nature, and seldom hesitates to throw the first punch. He is often depicted with a very pronounced New York accent. His personality can be fierce and sarcastic, and oftentimes delivers deadpan humor. He is intensely loyal to his brothers and sensei. He is named after the Italian painter and architect of the High Renaissance, Raphael.[9]
Splinter–The Turtles' sensei and adoptive father, Splinter is a Japanese mutant rat that learned the ways of ninjutsu from his owner and master, Hamato Yoshi. In the 1987 TV series, Archie Comics series, and the 2012 TV series, Splinter was Hamato Yoshi mutated into a humanoid rat. In the 2003 TV series, he was Hamato Yoshi's pet rat. He was mutated from a mysterious ooze from the TCRI building. In the IDW comics, he is Hamato Yoshi reincarnated as a mutated rat.
April O'Neil–A former lab assistant to the mad scientist Baxter Stockman, April is the plucky human companion of the Turtles. April first met the Turtles when they saved her from Baxter's Mouser robots. She embarks on many of the Turtles' adventures and aids them by doing the work in public that the Turtles cannot. In the 1987 TV series, Archie Comics series, the first three films, and the 2014 film reboot, April is a television news reporter. In the 2007 CGI film, Casey Jones and she own a shipping firm. In the 2012 series, April is a teenager who is rescued by the TMNTs and later given some "crash courses" in being a ninja by Splinter.
Casey Jones–A vigilante who wears a hockey mask to protect his identity, Casey Jones has become one of the Turtles' closest allies, as well as a love interest to April. Casey first encountered the Turtles after having a fight with Raphael. He fights crime with an assortment of sporting goods he carries in a golf bag, such as baseball bats, golf clubs, and hockey sticks.
The Shredder–A villainous ninjutsu master called Oroku Saki, he is the leader of the Foot Clan, an evil ninja clan. In every incarnation of the TMNT franchise, he has been the archenemy of the Turtles and Splinter as well as the main villain in most versions of the franchise. The Shredder prefers to use his armor instead of weapons in some versions.
Foot Soldiers/Ninjas – The ninjas of the Foot Clan who work for the Shredder. They are probably the most common villains that the Turtles encounter.
Karai–A female high-rank member of the Foot Clan, she has appeared in several different TMNT comics, cartoons, and films, as well as in multiple video games. In her original appearance she was a commander on the same level as Shredder while in some of her later incarnations of the character, she is closely related to Shredder as his adopted daughter or biological granddaughter as well second-in-command. In most works, she shares an ambiguous rivalry with Leonardo, which occasionally even borders on romantic interest.
Baxter Stockman – Baxter Stockman is a scientist and inventor who often acts as a enemy to the Turtles in various incarnations. He is known as the inventor of the mouser robots that appear in many versions, and is often depicted as allied with the Foot Clan, Krang, or going on his own.
Krang – Krang is a small brain-like alien warlord who often appears as one of the main villains of the franchise alongside The Shredder and the second arch-enemy of the turtles. The character was originally inspired by the Utroms, an alien race from the original comics, while in later versions he is a member of the Utroms. In some incarnations Krang would often team up with Shredder while some versions have them as rivals for conquest.
Bebop and Rocksteady – A criminal duo of a mutant warthog and rhinoceros, respectively, that were originally two human thugs that become the Shredder's henchmen in some versions. They are usually depicted as super-strong but not very smart.
Comics
Mirage

Eastman and Laird's Teenage Mutant Ninja Turtles premiered in May 1984, at a comic book convention held at a local Sheraton Hotel in Portsmouth, New Hampshire. It was published by Mirage Studios in an oversized magazine-style format using black and white artwork on cheap newsprint, limited to a print run of only 3,250 copies.[10] Through a clever media kit that included a press release in The Comics Journal #89 and a full-page ad placed in Comic Buyer's Guide #547, the public's interest was piqued and thus began the Turtle phenomenon. The small print runs made these early comics and trade magazines instant collector items, and within months, they were trading for over 50 times their cover price. The name "Mirage Studios" was chosen because of Eastman and Laird's lack of a professional art studio at the start of their career, before their creation made them both multimillionaires.
Mirage also published a bimonthly companion book entitled Tales of the Teenage Mutant Ninja Turtles, featuring art by Ryan Brown and Jim Lawson, which was designed to fill in the gaps of continuity in the TMNT universe. This put the original series and Tales in the same mainstream continuity, and the two are thus canon to each other. The title's first volume was from 1987–1989, released in alternating months with the regular Eastman and Laird book. All seven issues of volume one have been collected in trade paperback form twice, and 25 issues of volume two have been collected in trades of five issues each.
As the TMNT phenomenon proliferated to other media, Eastman and Laird  found themselves administrating an international merchandising juggernaut. However, this prevented the two creators from participating in the day-to-day work of writing and illustrating a monthly comic book. So, many guest artists were invited to showcase their unique talents in the TMNT universe. The breadth of diversity found in the various short stories gave the series a disjointed, anthology-like feel. Fans stuck with the series, and what was originally intended as a one-shot became a continuing series that lasted for 129 issues, spanning four separate volumes (having 62, 13, 23, and 32 issues in the four distinct volumes).
In June 1996, Image Comics took over publishing the title in what is considered "volume 3" of the series. It was a slightly more action-oriented TMNT series and although notable for inflicting major physical changes on the main characters, Peter Laird, co-creator of the TMNT, has said this volume is no longer in canon as he began publishing volume 4 at Mirage Publishing. As an explanation, he offered in the pages of the volume 4 (issue #8) letter column: "It just didn't feel right." [11]
After taking back the series from Image Comics, Mirage Studios resumed publication of a fourth volume in December 2001, under the simple title TMNT. After the publication of issue number 28, writer Peter Laird placed the series on an eight-month hiatus to devote himself to production of the 2007 TMNT movie. However, after that eight months had passed, Mirage's official website went on to list the series as in "indefinite hiatus". In January 2008, Mirage had finally confirmed that the series would return in May 2008. Issues 29 and 30 had a limited printing of 1,000 copies each, and were available through the official TMNT website. Although the purchase agreement with Nickelodeon allows Laird to produce up to 18 comics a year set in the original Mirage continuity, no new material was released in the next few years. The latest issue of TMNT volume 4 was issue #32 which came out in print May 4, 2014, and online on May 9, 2014, almost 4 years after issue #31 was last released. 
Teenage Mutant Ninja Turtles Adventures

Teenage Mutant Ninja Turtles Adventures was a comic-book series published from August 1988 to October 1995 by Archie Comics. The initial storylines were close adaptations of the 1987 TV series, but with the fifth issue, Eastman and Laird decided to hand the series over to Mirage Studios employees Ryan Brown and Stephen Murphy, who immediately abandoned the animated series adaptations and took the title in a decidedly different direction with all-new original adventures, including the uniting of several of the series' recurring characters as a separate team, the Mighty Mutanimals.
Dreamwave

A monthly comic inspired by the 2003 TV series was published by Dreamwave Productions from June to December 2003. It was written by Peter David and illustrated by LeSean Thomas. In the first four issues, which were the only ones directly adapted from the TV series, the story was told from the perspectives of April, Baxter, Casey, and a pair of New York City police officers.
IDW

In April 2011, IDW Publishing announced that they had acquired the license to publish new collections of Mirage storylines and a new ongoing series.[12] The first issue of the new series was released on August 24, 2011. Turtles co-creator Kevin Eastman and Tom Waltz write, with Eastman and Dan Duncan handling art chores.
Manga
The Turtles have appeared in several manga series.
Mutant Turtles(ミュータント・タートルズ,Myūtanto Tātoruzu) is a 15-issue series by Tsutomu Oyamada, Zuki mora, and Yoshimi Hamada that simply adapted episodes of the original American animated series.
Super Turtles (スーパータートルズ Sūpā Tātoruzu) is a three-issue miniseries by Hidemasa Idemitsu, Tetsurō Kawade, and Toshio Kudō that featured the "TMNT Supermutants" Turtle toys that were on sale at the time. The first volume of the anime miniseries followed this storyline.
Mutant Turtles Gaiden(ミュータント・タートルズ外伝,Myūtanto Tātoruzu Gaiden) by Hiroshi Kanno is a reinterpretation of the Turtles story with no connection to the previous manga.
Mutant Turtles III(ミュータント・タートルズ３,Myūtanto Tātoruzu Tsuri) is Yasuhiko Hachino's adaptation of the third feature film.
Mutant Turtles '95(ミュータント・タートルズ９５,Myūtanto Tātoruzu Kyūjūgo) is a 1995 series by Ogata Nobu which ran in Comic BomBom.
Mutant Turtles '96(ミュータント・タートルズ９６,Myūtanto Tātoruzu Kyūjūroku) is a continuation of the 1995 series when it continued to run through 1996.
Comic strip

A daily comic strip written and illustrated by Dan Berger began in 1990.  It featured an adventure story Monday through Friday and activity puzzles on weekends (with fan art appearing later). The comic strip was published in syndication until its cancellation in December 1996. At its highest point in popularity, it was published in over 250 newspapers.
Television series
First animated series (1987–1996)


When little-known Playmates Toys was approached about producing a TMNTs action figure line, they were cautious of the risk and requested that a television deal be acquired first.[13][14] On December 28, 1987, the TMNT's first cartoon series began, starting as a five-part miniseries and becoming a regular Saturday-morning syndicated series on October 1, 1988, with 13 more episodes. The series was produced by Murakami-Wolf-Swenson Film Productions, Inc. (later Fred Wolf Films). Mirage Studios does not own the rights to this cartoon series. The show places a much stronger emphasis on humor than the comics do. Here, the Ninja Turtles are portrayed as four wise-cracking, pizza-obsessed superheroes that fight the forces of evil from their sewer hideout, and they make their first appearance in masks color-coded to each turtle, where previously they had all worn red.[15]
The cast included new and different characters, such as Bebop and Rocksteady and the Neutrinos. Original characters such as Splinter, Shredder, and the Foot Soldiers stayed true to the comics in appearance and alignment only. Instead of being Hamato Yoshi's mutated pet rat, Splinter was a mutated Hamato himself. The Foot Soldiers changed from human ninjas to an endless supply of robotic grunts, allowing large numbers of them to be destroyed without anyone dying (this was a very important decision in terms of the show's child audience; excessive violence would have alienated parents of children, the show's target demographic). Krang, one of the series' most memorable villains, was inspired by the design of the Utrom, a benign alien race from the Mirage comics. The animated Krang, however, was instead an evil warlord from Dimension X. Baxter Stockman, whose race was changed from black to white either due to apprehension toward depicting a villainous African American character in a children's cartoon or that for Shredder to boss around a black Stockman would be perceived as racist. Either way, Stockman was rewritten as a shy and meek lackey to Shredder, later mutating into an anthropomorphic housefly. During the final two seasons of the show, to combat the rising popularity of Mighty Morphin Power Rangers, the lead villain switched to Lord Dregg, an evil alien overlord bent on world conquest by trying to distract the public into believing that the Turtles were the enemy instead of himself.
Starting on September 25, 1989, the series was expanded to weekdays and it had 47 more episodes for the new season. There were 28 new syndicated episodes for season 4 and only 13 of those episodes aired in 1990. The "European Vacation" episodes were not seen in the United States until USA Network started showing reruns in late 1993 and the "Awesome Easter" episodes were not seen until 1991. These episodes were delayed because of animation or scheduling problems.[16] The turtles are also well known for their use of idiomatic expressions characteristic of the surfer lingo of the time, especially by Michelangelo. Words and phrases included "bummer", "dude", "bogus", "radical", "far-out", "tubuloso", "bodacious", and possibly the most recognized, "cowabunga".[17] On April 21, 1990, a drug-prevention television special was broadcast on ABC, NBC, and CBS named Cartoon All-Stars to the Rescue that featured some of the most popular cartoons at the time; representing TMNT was Michelangelo, voiced by Townsend Coleman.
Starting on September 8, 1990 (with a different opening sequence), the show began its run on CBS. The CBS weekend edition ran for a full hour until 1994, initially airing a few Saturday-exclusive episodes back-to-back. Also, a brief "Turtle Tips" segment aired between the two episodes, which served as public-service announcement about the environment or other issues.  After 1994, the show was reduced to just a half-hour and only eight episodes per season were produced, grouped into a "CBS Action Zone" block that also featured WildC.A.T.s. and Skeleton Warriors, both of which were canceled after one season; though TMNTs retained their "Action Zone" introduction. The two shows in the block were also produced by Fred Wolf Films. The series ran until November 2, 1996, when it aired its final episode. Its enormous popularity gave rise to its numerous imitators, including the Battletoads, Cheetahmen, Wild West C.O.W.-Boys of Moo Mesa, Road Rovers, Street Sharks, Extreme Dinosaurs, and Biker Mice from Mars. Currently, all 193 episodes are available on DVD and VHS.
Original video animation

In addition to the American series, a Japan-exclusive two-episode anime original video animation (OVA) series was made in 1996, titled Mutant Turtles: Choujin Densetsu-hen. The OVA is similar in tone to the 1987 TV series and uses the same voices from TV Tokyo's Japanese dub of the 1987 TV series. The first episode was made to advertise the TMNT Supermutants toys. It featured the Turtles as superheroes, that gained costumes and superpowers with the use of Mutastones, while Shredder, Bebop and Rocksteady gained supervillain powers with the use of a Dark Mutastone. As with the Super Sentai and Power Rangers franchises, the four Turtles could combine to form the giant Turtle Saint. The second episode was created to advertise the Metal Mutants toys in which the characters gain Saint Seiya-esque mystical metal armor that can transform into beasts.
Live-action series (1997–1998)


In 1997–1998, the Turtles starred in a live-action television series called Ninja Turtles: The Next Mutation that directly follows the events of the first three movies. A fifth turtle was introduced, a female named Venus de Milo, who was skilled in the mystical arts of the shinobi.[15] The series was intended as a loose continuation of the movie franchise, as Shredder had been defeated and the Ninja Turtles encountered new villains. Other connections to the feature films include the fact that Splinter's ear was cut, the Foot Soldiers were humans, and the Turtles lived in the abandoned subway station seen in the second and third movies. The Next Mutation Turtles made a guest appearance on Power Rangers in Space.[18] It was canceled after one season of 26 episodes.
Second animated series (2003–2009)


In 2003, a new TMNT series produced by 4Kids Entertainment began airing on the "FoxBox" (later renamed "4Kids TV") programming block. It later moved to "The CW4Kids" block. The series was co-produced by Mirage Studios,[19] and Mirage owned one-third of the rights to the series. Mirage's significant stake in creative control resulted in a cartoon that hews more closely to the original comics, creating a darker and edgier feel than the 1987 cartoon, but still remains lighthearted enough to be considered appropriate for children.
This series lasted until 2009, ending with a feature-length television movie titled Turtles Forever, which was produced in conjunction with the 25th anniversary of the TMNTs franchise and featured the Turtles of the 2003 series teaming up with their counterparts from the 1987 series. 4Kidstv.com featured all the episodes of the series, until September 2010, when Nickelodeon bought the series and air the series occasionally on Nicktoons and Nickelodeon normally during TMNTs marathons.
Third animated series (2012–2017)


Nickelodeon acquired the global rights to Teenage Mutant Ninja Turtles from the Mirage Group and 4Kids Entertainment, Inc. and announced a new CGI-animated TMNT television series.[20][21][22] The 2012 version is characterized by anime-like iconography and emphasis on mutagen continuing to wreak havoc on the everyday lives of the Turtles and their enemies. The series ran for five seasons.
Fourth animated series (2018)


Nickelodeon announced a new 2D animated series based on the franchise, which debuted on September 17, 2018.[23][24]
Feature films

The Turtles have appeared in six feature films. The first three are live-action features produced in the early 1990s: Teenage Mutant Ninja Turtles (1990), Teenage Mutant Ninja Turtles II: The Secret of the Ooze (1991), and Teenage Mutant Ninja Turtles III (1993). The Turtles were played by various actors in costumes featuring animatronic heads, initially produced by Jim Henson's Creature Shop. The fourth film is a CGI-animated film titled simply TMNT and released in 2007.
A reboot, titled Teenage Mutant Ninja Turtles produced by Platinum Dunes, Nickelodeon Movies, and Paramount Pictures, directed by Jonathan Liebesman, and produced by Michael Bay, was released on August 8, 2014.[8] A sequel, Out of the Shadows was released on June 3, 2016.[25]
Merchandise
Among the first licensed products to feature the TMNT was a tabletop role-playing game titled Teenage Mutant Ninja Turtles & Other Strangeness, published by Palladium Books in 1985, and featuring original comics and illustrations by Eastman and Laird. The game features a large list of animals, including elephants and sparrows, that are available as mutant player characters. Several more titles were in this genre, including Teenage Mutant Ninja Turtles Adventures, Truckin' Turtles, Turtles Go Hollywood, Teenage Mutant Ninja Turtles Guide to the Universe, and Transdimensional Teenage Mutant Ninja Turtles.
In 1986, Dark Horse Miniatures in Boise, Idaho, produced an attendant set of lead figurines; unlike later incarnations, the bandannas on the store's display set were painted all black before the multicolored versions were released to help younger readers distinguish between the four characters other than their weaponry. Palladium allowed the license to lapse in 2000, in part due to declining sales stemming from the "kiddification" of the animated and live-action incarnations to that point. However, Palladium's publisher, Kevin Siembieda, has indicated a potential willingness to revisit the license given the franchise's recent moves closer to its roots.[26]
The franchise generated merchandise sales of $175 million in 1988 and $350 million in 1989.[27] By 1994, it was the most merchandisable franchise, having generated a total revenue of $6 billion in merchandise sales up until then.[28]
Toys

During the run of the 1987 TV series, Playmates Toys produced hundreds of TMNT action figures, along with vehicles, playsets, and accessories, becoming one of the top collectibles for children.[29] Staff artists at Northampton, Massachusetts-based Mirage Studios provided conceptual designs for many of the figures, vehicles, and playsets and creator credit can be found in the legal text printed on the back of the toy packaging. In addition, Playmates produced a series of TMNTs/Star Trek crossover figures, due to Playmates holding the Star Trek action-figure license at the time. Playmates employed many design groups to develop looks and styles for the toy line, including Bloom Design, White Design, Pangea, Robinson-Clarke, and McHale Design. The marketing vice president of Playmates, Karl Aaronian, was largely responsible for assembling the talented team of designers and writers, which in turn, helped germinate continued interest in the toy line.
Never before in toy history did an action-figure line have such an impact for over two decades, generating billions of dollars in licensing revenue. The series was highly popular in the UK, where in the run-up to Christmas, the Army & Navy Store in London's Lewisham devoted its entire basement to everything Turtle, including games, videos, costumes, and other items. Playmates continue to produce TMNT action figures based on the 2003 animated series. The 2007 film TMNT also gave Playmates a new source from which to make figures, while National Entertainment Collectibles Association produced a series of high-quality action figures based on character designs from the original Mirage comics. In 2012, a new toy line and a new classic toy line from Playmates were announced to be released.[30]
Video games

The first console video game based on the franchise, titled Teenage Mutant Ninja Turtles, was released for the Nintendo Entertainment System (NES) by Konami under their "Ultra Games" label in 1989 and later ported to home computers and eventually for the Wii on the Virtual Console. Also released by Konami in 1989 was an arcade game, also titled simply Teenage Mutant Ninja Turtles, later ported to the NES as Teenage Mutant Ninja Turtles II: The Arcade Game, leading to an NES-only sequel, Teenage Mutant Ninja Turtles III: The Manhattan Project, which used the look of the arcade game, as opposed to the first NES game. The next Turtles game, Teenage Mutant Ninja Turtles: Turtles in Time, was released in 1991 as an arcade game, and was later ported to the Super Nintendo Entertainment System (Super NES) in 1992, titled Teenage Mutant Ninja Turtles IV: Turtles in Time, with a sequel numbering to the NES titles appended. Teenage Mutant Ninja Turtles: The Hyperstone Heist was also created for the Sega Genesis in the same year, and used many of the art assets from TMNT IV. There was also a trilogy of TMNT video games for the original Game Boy system made by Konami, consisting of: Teenage Mutant Ninja Turtles: Fall of the Foot Clan, Teenage Mutant Ninja Turtles II: Back from the Sewers, and Teenage Mutant Ninja Turtles III: Radical Rescue. As the video game series progressed, and the Ninja Turtles' popularity began to decline in the mid-1990s, the video games changed direction. Teenage Mutant Ninja Turtles: Tournament Fighters was released as a set of one-on-one fighting game similar to the Street Fighter series; versions were released for the NES, SNES, and Genesis, each a distinct game.
Konami also acquired the license to adapt the 2003 TV series into a video game franchise, resulting in a new series of games with 3D gameplay inspired by the old TMNT beat 'em up games, consisting of Teenage Mutant Ninja Turtles (2003 video game), Teenage Mutant Ninja Turtles 2: Battle Nexus, Teenage Mutant Ninja Turtles 3: Mutant Nightmare, and Teenage Mutant Ninja Turtles: Mutant Melee.
In 2006, Ubisoft acquired the rights for TMNT games, beginning with a game based on the 2007 animated feature film, along with a distinct game for the Game Boy Advance similar in style to the Konami arcade games.[31][32]  A beat 'em up game Teenage Mutant Ninja Turtles: Arcade Attack was released for the Nintendo DS in 2009, to coincide with the series' 25th anniversary.[33] In 2013, Activision released the downloadable game Teenage Mutant Ninja Turtles: Out of the Shadows, based on the 2012 TV series and developed by Red Fly Studio for the Xbox Live Arcade, PlayStation Network and Steam.[34]
On January 25, 2016, Activision and PlatinumGames announced Teenage Mutant Ninja Turtles: Mutants in Manhattan for the PlayStation 4, PlayStation 3, Xbox One, Xbox 360, and PC. The game is described as a third-person, team-based brawler. The campaign will be playable either single-player or co-op and will have an original story written by Tom Waltz, IDW comic writer and editor. The art style is based on long time TMNT comic artist Mateus Santolouco.[35]
Teenage Mutant Ninja Turtles Legends, a Free to play Role-playing video game has been released by Ludia in summer 2016 for iPhone, iPad, Android, and Kindle Fire. It is based on the Teenage Mutant Ninja Turtles (2012 TV series).
The Teenage Mutant Ninja Turtles appear as playable characters in the DC Comics fighting game Injustice 2 as a part of the "Fighter Pack 3" downloadable content.
In other media
Tabletop role playing game
In 1985, Palladium Books published Teenage Mutant Ninja Turtles & Other Strangeness.[36] This was a stand-alone game, as well as acting as an expansion for their game Rifts. The game used many key mechanics from the Palladium system. The game itself is limited to which martial arts are available, but a separate book, Ninjas and Superspies,[37] increased the amount available to a choice of 41 martial arts styles. Examples of animals created are included in the appendices as potential antagonists, including the Terror Bears, Caesers Weasels, and Sparrow Eagles, as well as including stats for the Turtles and other characters.
Food tie-ins

During the height of their popularity, the Turtles had a number of food tie-ins.[38]  Among the most notable of these products was Ninja Turtles Cereal, produced by Ralston-Purina as a kind of "Chex with TMNT-themed marshmallows" which also came with a small pouch of Pizza Crunchabungas, pizza-flavored corn snacks in the shape of pizzas (the commercial starred the Ninja Turtles as Will Vinton-created claymations); Hostess Ninja Turtles Pudding Pies, featuring a green sugar crust and vanilla pudding inside; and Royal OOZE Gelatin Desserts, distributed by Nabisco under "Royal Gelatin" in three different flavors: orange, strawberry, and lime. Shreddies used to give out TMNT toys in their boxes when the cereal advertising was still geared toward children. One example of a TMNT prize was rings featuring a character on the cartoon (1992). There was also green Ninja Turtle ice cream with different toppings according to which turtle flavor one ordered. Chef Boyardee also released a canned pasta with the pasta in the shapes of the four turtles.[39]
Concert tour
To capitalize on the Turtles' popularity, a concert tour was held in 1990, premiering at Radio City Music Hall on August 17.[40][41] The "Coming Out of Their Shells" tour featured live-action turtles playing music as a band (Donatello, keyboards; Leonardo, bass guitar; Raphael, drums and sax; Michelangelo, guitar) on stage around a familiar plotline: April O'Neil is kidnapped by the Shredder, and the Turtles have to rescue her.[42] The story had a very Bill-n'-Ted-esque feel, with its theme of the power of rock n' roll literally defeating the enemy, in the form of the Shredder (who only rapped about how he hates music) trying to eliminate all music. A pay-per-view special highlighting the concert was shown, and a studio album was also released.[43] The track listing is as follows:
Concert tour track list




"Coming Out of Our Shells!"
"Sing About It"
"Tubin'"
"Skipping Stones"
"Pizza Power"
"Walk Straight"
"No Treaties"
"Cowabunga"
"April Ballad"
"Count on Us"
Since the tour was sponsored by Pizza Hut in real life,  many references are made to their pizza. Empty Pizza Hut boxes are seen onscreen in the "Behind the Shells" VHS. As part of a cross-marketing strategy, Pizza Hut restaurants gave away posters, audio cassettes of "Coming Out of Their Shells", and "Official Tour Guides" as premiums. The original show of the tour was released on video with a making of video also released. The song "Pizza Power" was later used by Konami for the second arcade game Teenage Mutant Ninja Turtles: Turtles in Time.
At the Disney-MGM Studios theme park
On June 30, 1990, the TMNT appeared in the "New York Street" section of Disney-MGM Studios theme park in Orlando. Emerging from their Turtle Party Wagon, they would "ninja dance" across the stage while April performed the theme song to the show. After the main show was done, they posed for pictures and signed autographs. The Turtles also made appearances in Disney's Very Merry Christmas Parade to sing their own rendition of "Santa Claus is Coming to Town". They also appeared during the Easter parade dancing to their single "Pizza Power!" The Turtles' live shows and appearances ceased production in 1996.
Parodies

Although the TMNT had originated as something of a parody, the comic's explosive success led to a wave of small-press, black and white comic parodies of TMNT itself, including Adolescent Radioactive Black Belt Hamsters, Pre-Teen Dirty-Gene Kung-Fu Kangaroos, and a host of others. Dark Horse Comics' Boris the Bear was launched in response to these TMNT clones; its first issue was titled "Boris the Bear Slaughters the Teenage Radioactive Black Belt Mutant Ninja Critters". Once the Turtles broke into the mainstream, parodies also proliferated in other media, such as in satire magazines Cracked and Mad and numerous TV series of the period. The satirical British television series Spitting Image featured a recurring sketch "Teenage Mutant Ninja Turds".[44]

Controversies
Departure from origins
The Turtles engaged in a greater amount of overt violence in the pages of the early Mirage comic book series by Eastman and Laird. As the TMNT were introduced into the mainstream, they were radically redesigned. In issue #19 of Teenage Mutant Ninja Turtles, the creators published an editorial addressing any possible concerns of readers as a result of this. It stated, in part: "We've allowed the wacky side to happen, and enjoy it very much. All the while, though, we've kept the originals very much ours–forty pages of what we enjoy and want to see in our books, whether it comes from our own hands or from those of the talented people we work with."[45] In the film Turtles Forever, the original Mirage Turtles refer to their counterparts from the 1987 cartoon series and the 2003 cartoon series as "sell-outs", in reference to their colorful accessories (the originals are conveyed in black and white).
Teenage Mutant "Hero" Turtles 

Upon TMNT's first arrival in the United Kingdom the name was changed to "Teenage Mutant 'Hero' Turtles" (or TMHT, for short), since the British Broadcasting Corp deemed the word ninja to have excessively violent connotations for a children's program.[46] Consequently, everything related to the Turtles (comic books, video games, toys, etc.) was renamed before being released in the UK as well as various other European countries.
The lyrics were also changed, such as changing "Splinter taught them to be ninja teens" to "Splinter taught them to be fighting teens". The policies also had other effects, such as editing out use of Michelangelo's nunchaku (which were at the time banned by James Ferman, chairman of the BBFC, from appearing in films and generally toning down the usage of all the turtles' weapons.)[47] To head this problem off, the showrunners elected to remove Michelangelo's nunchaku entirely during season three, replacing them with a grappling hook called the "Turtle Line" that served as Mikey's signature weapon for the rest of the show's run.[3]
In Italy, Spain and Portugal, they kept Michelangelo's nunchaku but the "TMHT" logo could be seen in the intro, as it was not edited to reflect the title in each of those translations. In Spain the cartoon was originally aired in regional TV channels and thus had different dubs in addition to Castillian: Galician and Catalan; in the Galician version, the title As Tartarugas Mutantes ("The Mutant Turtles") was used. The Italian and European Portuguese dubs also had few edits.
However, when the live-action movie came out in 1990, the Ninja of the title was kept even in the UK. In time, nunchaku scenes were retained in previously-censored movies such as those of Bruce Lee. The same went for the PAL releases of the early video games, which had Michelangelo's weapon of choice fully visible and usable. By the time of the 2003 TV series, these censorship policies had been abolished, and no changes have occurred in the content of the show. The name "Teenage Mutant Ninja Turtles" remained unchanged for the 2003 TV series. As a result, in the UK, the 1987 TV series is still called Teenage Mutant Hero Turtles and the 2003 TV series is called Teenage Mutant Ninja Turtles. In 2009, Lionsgate Home Entertainment released the 25th Anniversary Collectors Edition on Region 2 DVD in the UK. This 3-Disc set contains all the episodes of Seasons 1 and 2 and 4 episodes from the final season, as well as a 1-Disc DVD with the first few episodes of Season 1. This release features the original, unedited episodes under the "Ninja Turtles" title, and also marks the first time the show has been released and left uncensored in the UK.
Ownership rights
Due to various movie and television deals, the various TMNT films and television series have split between various companies, with Mirage Studios having retained copyright and trademark until October 19, 2009, at which point the rights for the entire TMNT franchise were sold by co-creator Peter Laird to Nickelodeon.[48]
Television
The original animated series (1987–1996) was produced by Fred Wolf Films Dublin (as Murakami Wolf Swenson (MWS) and Murakami Wolf Dublin (MWD) during earlier seasons), and syndicated by Group W. The series itself is owned by Wolf Films, with home entertainment rights residing with Lions Gate Entertainment, and until recently, syndication rights belonged to Nickelodeon's former corporate sibling CBS Television Distribution. The initial five-part miniseries (retroactively considered the first season) was copyrighted by Playmates Toys, although their rights to those episodes were bought out by Fred Wolf Films.
Ninja Turtles: The Next Mutation was produced by Saban Entertainment, and as of September 2011, is owned and distributed by Saban Brands.[49][50][51]
The second animated series (2003–2009) was a co-production between Mirage Studios and 4Kids Entertainment. Nickelodeon's October 19, 2009 buyout of the TMNT franchise included an approximate $9.75 million payment to 4Kids to terminate its right to serve as the merchandise licensing agent prior to the scheduled expiration of the representation agreement in 2012.[7][52] Due to the buyout, all future TMNT film and television series rights are owned by Nickelodeon.[48] Nickelodeon also gained the rights to the 2003 series after terminating 4Kids' contract.
Films
The first three TMNT live-action films were produced by Golden Harvest, with New Line Cinema (now a sister company of Warner Bros. Entertainment) distributing the films in the United States, with 20th Century Fox distributing the second and third films in most other territories. The first two films were copyrighted by the UK-based Northshore Investments.  The third film was copyrighted by Clearwater Holdings. The fourth film was produced by Imagi Animation Studios, and released by Warner Bros. Entertainment in association with the Weinstein Company.
Michael Bay produced a feature film directed by Jonathan Liebesman simply titled Teenage Mutant Ninja Turtles, and was released on August 8, 2014. A sequel, Teenage Mutant Ninja Turtles: Out of the Shadows, was released on June 3, 2016, with Megan Fox and Will Arnett reprising their roles and debuting Stephen Amell as Casey Jones. Dave Green replaced Liebesman as the director.
Comic books
Initially, Mirage allowed employees and freelancers to retain the rights to characters they created for the TMNT Universe but had never licensed for media and merchandise outside comic books.  Eventually, due to the difficulty of keeping track of everyone's rights, Mirage made TMNT character creators sign retroactive work-for-hire contracts. One creator who did not sign over the rights to his TMNT work was Swamp Thing veteran Rick Veitch.[53]
