Teenage Mutant Ninja Turtles

Teenage Mutant Ninja Turtles (initially known as Teenage Mutant Hero Turtles in some European countries due to controversy at the time) is an American animated television series produced by the studio Murakami-Wolf-Swenson and the French company IDDH. The pilot episodes were shown during the week of December 28, 1987–January 1 1988 in syndication as a five-part miniseries  and the show began its official run on October 1, 1988. Since then the show and franchise has become a world-wide phenomenon. The series featured the Teenage Mutant Ninja Turtles characters created in comic book form by Kevin Eastmanand Peter Laird. The property was changed considerably from the darker-toned comic, to make it more suitable for children and the family.[3] The initial motivation behind the Teenage Mutant Ninja Turtles animated series was that, upon being approached to create a toy line, Playmates Toys was uneasy with the comic-book characters' small cult following.[4] They requested that a television deal be acquired first, and after the initial five-episode series debuted, the California toy company released their first series of Ninja Turtles action figures in the summer of 1988.[5] The two media would correspond in marketing style and popularity for many years to come.

David Wise and Patti Howeth wrote the screenplay for the first five-part miniseries.[1] When the series continued in the second season, comic artistJack Mendelsohn joined the show as the executive story editor. Wise went on to write over seventy episodes of the series, and was executive story editor for four later seasons as well. Wise left the series partway through the ninth season, and Jeffrey Scott took over as the story editor and chief writer for the rest of the show's run.

The show was in Saturday morning syndication from October 1, 1988 to September 9, 1989, and became an instant hit. The show was expanded to five days a week and aired weekday afternoons in syndication in most markets from September 25, 1989 to September 17, 1993.[2] Starting on September 8, 1990 (with a different opening sequence), the show began its secondary run onCBS's Saturday morning lineup, beginning as a 60-minute block from 1990 to 1993, initially airing a couple of Saturday exclusive episodes back to back. There would also be a brief "Turtle Tips" segment in between the two episodes which served as PSA about the environment or other issues. There were a total of 20 "Turtle Tips" segments produced and aired. Beginning in 1994, the show began airing as a 30-minute block until the series ended. The series ran until November 2, 1996, when it aired its final episode.

The show helped launch the characters into mainstream popularity and became one of the most popular animated series in television history.Breakfast cereal, plush toys, and all manner of products featuring the characters appeared on the market during the late 1980s and early 1990s.[6] A successful Archie Comics comic book based on the animated show instead of the original black-and-white comics was published throughout the early 1990s and late 2000s. Action figures were top-sellers around the world. In 1990, the cartoon series was being shown daily on more than 125 television stations, and the comic books sold 125,000 copies a month.

Seasons 1–7
Main article: List of Teenage Mutant Ninja Turtles (1987 TV series) episodes

The origins story in the 1987 television series deviates significantly from the original Mirage Studios comics. In this version, Splinter was formerly human, an honorable ninja master named Hamato Yoshi (ハマト・ヨシ?) who studied art history as a hobby. He was banished from the Foot Clan (a Japanese dynasty of ninjas founded by one of his distant ancestors[7]) after one of his students, the power-hungry and seditious Oroku Saki (who resented Yoshi's leadership within the clan and aspired to usurp him), set him up for an offense against a visiting master sensei. One day, Saki pinned Yoshi's dogi to the wall with a knife, preventing him from kneeling before the sensei, which was seen as an insult. When Yoshi removed the knife, the sensei was again insulted, believing that Yoshi was drawing the blade in an attempt to kill him. Disgraced, Yoshi left his native Japan and relocated to New York City without a penny to his name. Now homeless, he was forced to live in the sewers with the rats as his only friends. Meanwhile, Saki is given command of the Foot Clan, which he corrupts and transforms into a criminal organization.

Sometime later, Yoshi adopted four turtles after they were accidentally dropped into the sewer system by an unnamed boy, who had recently bought them from a pet store. He returns from his explorations around New York City one day to find the turtles covered with a strange glowing ooze. This substance caused the turtles, who were most recently exposed to Yoshi, to become humanoid, while Yoshi, who was most recently exposed to sewer rats, became a humanoid rat, and was given the name "Splinter" by the turtles. This, and the following Archie TMNT Adventures comics (which is loosely based on the 1987 cartoon series), is the only origin story in the TMNT franchise in which the Turtles come to Yoshi before being exposed to the mutagen. The television series also differs in that Yoshi himself becomes a rat, whereas in most other versions, Splinter is Yoshi's pet rat and becomes humanoid after being exposed to mutagen. This is also the only version in which the Turtles become fully grown immediately after exposure to the mutagen, whereas Splinter raises them from infancy in other versions.

Yoshi raises the four turtles as his sons and trains them in the art of ninjitsu. He names them after his favorite Italian renaissance artists: Donato di Niccolò di Betto Bardi (Donatello), Leonardo da Vinci (Leonardo), Michelangelo di Lodovico Buonarroti Simoni (Michelangelo), and Raffaello Sanzio da Urbino (Raphael). In most versions, the Turtles tend to go by nicknames Don/Donnie, Leo, Mikey and Raph, but in this version they are always addressed by their full names. Each Turtle wears a mask over his eyes with a distinctive color (whereas in the original Mirage comics, they all had red masks): blue for Leonardo, purple for Donatello, red for Raphael, and orange for Michelangelo; and they are each trained in the art of a distinct weapon, with Leonardo wielding katanas, Donatello wielding a bo staff, Raphael wielding sais, and Michelangelo wielding nunchuks (which were later replaced with a grappling hook, although the nunchuks still appeared on occasion).[8]

Oroku Saki eventually leaves Japan and tracks Yoshi to New York City, where he intends to destroy him once and for all. It is also around this time that he begins working with Krang, a disembodied alien brain from Dimension X who ruled his native realm with an iron fist until he was stripped of his body and banished to earth. Saki takes on a new pseudonym, "The Shredder", donning a suit covered with razor spikes, and complemented by a long cape, a metal samurai helmet, and a metal mask over his mouth.[9] Since leaving Japan, his ambitions have grown from usurping leadership of the Foot Clan, to world domination. To this end, Krang provides the Shredder with a vast array of powerful technology from Dimension X, including the Technodrome, and funds most of his schemes throughout the series (in exchange for building Krang a powerful new android body, which he eventually does by the end of season 1).

It becomes clear early on in the series that the mutagen which transformed the Turtles and Splinter into their new forms was dumped into the sewers by Shredder in an effort to murder Yoshi, as he had mistakenly believed it to be a deadly poison rather than a transformative agent. After several years of training under Splinter, the Turtles set out to find whoever is responsible for their transformation, and upon learning that Shredder was behind it, they vow to put an end to his ongoing criminal career and restore Splinter back to his human form, despite the risk that they themselves could be de-mutated and changed back into ordinary turtles, thus losing all of their humanoid abilities. Along the way, they befriend Channel 6 news reporter April O'Neil after rescuing her from a gang of street punks (among them were Bebop and Rocksteady in their pre-mutated forms) who had chased her into the sewers. The Turtles, who had rarely left the sewers prior to meeting April, also began to take on the role of semi-vigilante crime fighters, operating outside of the jurisdiction of law enforcement, much likeCasey Jones. Despite this, they frequently have to deal with citizens misunderstanding them, which is due in no small part to the efforts of Burne Thompson, April's employer, and Vernon Fenwick, a Channel 6 cameraman, who distrust the Turtles and frequently blame them for the trouble that Shredder and Krang cause. As a result, they mainly have to rely on April (either via Turtle-com, or Channel 6 news reports) to inform them of crimes in the city, and to counteract Burne and Vernon's smear campaigns against them with her own news coverage of the Turtles, portraying them as a force for good, although doing so frequently lands her in trouble with her employers and various criminals throughout the city. Reluctant to expose themselves to the outside world, the Turtles usually wear disguises whenever they leave the sewers, although this is slowly relaxed as the series progresses and they gain the trust of the broader populace, whom they have saved from Shredder and other villains on many occasions. Even at Channel 6, the Turtles befriend secretary Irma from the second season onwards.

Shredder, Krang, Bebop & Rocksteady (two street thugs who were mutated into a humanoid warthog and rhinocerosrespectively, after being exposed to Shredder's mutagen and the aforementioned animals, which were stolen from the zoo),Baxter Stockman (an inventor who is briefly employed by Shredder until he is sent into Dimension X, where he is accidentally transformed into a mutant fly by Krang, who had intended to execute him; ever since then, he has sought revenge against both the Turtles and Shredder/Krang for his transformation and for attempting to kill him), and their legions of Foot soldiersrepeatedly try to destroy the Turtles and take over the world. Much of their quest for world domination hinges on repowering the Technodrome (Krang's mobile fortress, and their base of operations) and bringing it to the earth's surface, as it was either buried deep under New York City (season 1), stuck in Dimension X (seasons 2 and 4), embedded in the earth's core(season 3), stranded in the Arctic (season 5), or at the bottom of the Arctic Ocean (seasons 6 and 7). However, their plans always fail, often landing the villains in humorous predicaments. Some episodes feature other, usually minor villains as antagonists, such as the Rat King (a homeless man living in the sewers who has control over rats and believes that he is one himself; he considers all other species inferior and aspires to establish a rat-controlled government above ground), Leatherhead (a mutated Florida crocodile who speaks with a Cajun accent), Slash (a savage, humanoid mutant turtle with brute strength and low intelligence; he was Bebop's pet turtle before he was exposed to mutagen), General Traag and Granitor (two high ranking Rock Warriors who are loyal to Krang and command a vast army in Dimension X, which Krang often tries to bring to the earth in order to conquer it), and many others. Some episodes also involve the TMNT getting themselves and the city out of a mess that one of the Turtles (usually Michelangelo or Donatello) inadvertently cause.

Seasons 8–10
In the last three seasons, the show (which had already lasted well past the average lifespan of most Saturday-morning cartoon series) went through dramatic changes. The stories within these seasons are typically known among viewers as the "Red Sky" episodes. The show's humor had been toned down significantly, the animation became darker, the color of the sky in each episode was changed to a continuous and ominous dark-red sky (which was commonplace with newer action-oriented children's programming at the time), the theme song was changed, the introduction sequence added in clips fromthe first live-action film, and the show took on a darker, more action-oriented atmosphere.[10] The series' main antagonists—Shredder, Krang, Bebop, and Rocksteady—who had hitherto been depicted as dangerous but comically inept villains, were now portrayed as a more menacing, unified threat. Both Shredder and Krang had lost much of their earlier resentment towards each other (with Shredder even going as far as to risk his own life to save Krang on multiple occasions), and Shredder had evolved into a more vengeful, bloodthirsty version of his earlier self. Bebop and Rocksteady also gained a certain degree of intelligence and joked around much less. The Turtles, likewise, underwent a few changes. Although their personalities remained mostly the same, their demeanor evolved into a more serious and determined one than in prior seasons. Michelangelo, for example, did not obsess over pizza or goof off as much as before, and Raphael made lighthearted, fourth-wall breaking jokes far less often. And in contrast to earlier episodes in which the Turtles would spend most of their time training, relaxing, or partying, and only countering a threat when it arose, they devoted most of their time and energy to tracking down Shredder, Krang, or Lord Dregg, and putting them away for good. Additionally, a number of recurring villains had been written out of the show by this point, including Baxter Stockman (who is trapped in dimensional limbo), Leatherhead (whose fate is unknown, but it is assumed that he has long since returned to the Florida swamps), Pinky McFingers (who has been in jail since season 6), Slash (who was last seen running away at the end of "Night of the Rogues" in season 7), Big Louie (fate unknown, but presumably in jail), Don Turtelli (presumably in jail), and Groundchuck/Dirtbag (jailed on the Turtleoid planet). The Rat King, however, makes one final appearance in the second episode of season 8, where he is defeated once more by the Turtles and apprehended by the police, never to be seen again. With the exception of April, the Channel 6 news crew were all gradually phased out of the show by the end of season 8, and many other secondary protagonists (such as the Neutrinos, the Punk Frogs, Mondo Gecko, Zach, Kerma) were dropped from the show completely.

At the end of the seventh season, the Turtles send the Technodrome through a portal into Dimension X, but without Shredder or Krang. As a result, the villains are now stranded on earth without any weapons or power, and they are forced to work out of an old science building until they can find a way back into Dimension X and retrieve the Technodrome (which had landed in a black hole with General Traag and his battalion of Rock Warriors trapped inside). The Turtles, taking advantage of the situation, relentlessly pursue their arch enemies in an effort to put an end to their schemes once and for all. Eventually, Shredder and Krang (along with Bebop and Rocksteady) build a new portal into Dimension X and reclaim the Technodrome, although the Turtles manage to track them down with the help of Gargon (a mutated resident of Dimension X who was being held prisoner by Shredder and Krang). Gargon initially intended to betray the Turtles by leading them into Shredder's trap on the planet Balaraphon, but he switches sides after seeing them rescue innocent villagers from Krang's army of Rock Soldiers. At the end of season 8, the TMNT finally banish Shredder, Krang, Bebop, and Rocksteady to Dimension X by destroying the engines and the "trans-dimensional portal" of the Technodrome (although the Turtles were able to use the portal at least twice afterwards; the reasons for this are unexplained), preventing them from returning to Earth.[11] From season 9 onwards, a new villain called Lord Dregg (voiced by Tony Jay), an evil alien warlord from Dimension X, appeared as the new chief nemesis. He begins a propaganda campaign against the Turtles, turning the general population against them and in favor of him and his forces. Although Dregg is outed as a villain at the end of season 9,[12] the Turtles are never able to regain the trust of the broader population, which is mainly due to an earlier smear campaign by Burne and Vernon, who blamed the Turtles for the destruction of the Channel 6 building in season 8. Additionally, the Turtles began to suffer from mutations that would temporarily transform them into monstrous hulks with diminished intelligence, a problem that would not be completely resolved until season 10. The TMNT also gain a new ally in the form of Carter, a brash African American male who initially sought out Master Splinter for training in ninjitsu, but is eventually exposed to mutagen and contracts an incurable mutation disease.

In the final season of the series, Dregg's sycophantic henchman Mung encounters Shredder and Krang, who are still stranded in Dimension X. They told him that they had battled the Turtles for years, but even though Shredder claimed to have destroyed them (probably out of embarrassment and humiliation for his failure to actually do so), Mung knew that he was lying. No mention is made of Bebop or Rocksteady, suggesting that they are either dead or have long since parted ways with Shredder and Krang. Soon afterwards, Mung returns to Dregg's ship and informs him of their encounter, and Dregg decides to bring both Shredder and Krang back from Dimension X to help him fight the Turtles. However, the pair immediately rebel against Dregg and leave, continuing on where they left off before they were banished at the end of season 8. Back on earth, Shredder and Krang kidnap April O'Neil and do battle with the Turtles once more, although they are all soon transported back to Dregg's lair. The Turtles initially have the upper hand in the fight, but Shredder and Krang are able to subdue them after reluctantly agreeing to work with Dregg. As he prepares to drain the Turtles of their life energies, Shredder and Krang betray Lord Dregg and force him onto one of the operating tables, intending to drain both him and the Turtles of their power (which is what Dregg had intended to do to Shredder and Krang all along). Dregg, however, manages to escape and uses his microbots to capture Shredder and Krang. Although he successfully drains the Turtles and Krang of their life energies, Shredder breaks free before Dregg is able to take anything from him.[13] Shredder spends the duration of the next two episodes finding a way to heal Krang (which he eventually does) and dispose of Dregg so that they may take control of his armies and conquer the Earth, but in the ensuing confrontation they are permanently transported back to Dimension X, never to be seen again. In the same episode, Carter also bids farewell to the Turtles as he travels to the future to look for a cure for his mutation.[14] In the final episode of the series, Michelangelo and Donatello travel to Dimension X to retrieve Krang's mechanical body in the (now abandoned and completely destroyed) Technodrome, which is sitting on a hill standing upright (whereas at the end of season 8, an alien plant had dragged it down into a deep pit), suggesting that Shredder and Krang initially tried to repair the Technodrome before declaring it a lost cause. Shredder, Krang, Bebop, and Rocksteady are nowhere to be seen, and it is assumed that they are either dead or still somewhere in Dimension X. The Turtles eventually find Krang's suit and use it in a final confrontation with Dregg, which ends with the Turtles banishing Dregg to Dimension X (and possibly killing him as well, by sending Krang's android suit back with him as it is about to explode). Splinter congratulates the Turtles on their victory and, now that all of their enemies have been vanquished, states that he has nothing more to teach them. He calls the Turtles his equals, and bids them farewell.[15]

Subsequent works
In 2009, the Turtles, Shredder, Krang, and various other characters from the 1987 series returned for the 25th anniversary crossover movie Turtles Forever, in which they meet up with their counterparts from a series produced in 2003. Due to financial reasons, none of the original voice actors were able to reprise their roles, and replacement actors were used instead. In relation to this particular series, the plot suggests the film is most likely set sometime before Shredder and Krang are banished to Dimension X, during the time the Technodrome is stuck near the earth's core.

In April 2013, Ciro Nieli, the executive producer of the 2012 Turtles series, confirmed in an interview that the 1987 Turtles would cameo in a one-hour special in season 2. Cam Clarke, Townsend Coleman, Barry Gordon and Rob Paulsen (who voiced Donatello in the 2012 series) reprise their roles as Leonardo, Michelangelo, Donatello, and Raphael, respectively, in the closing of the episode "Wormquake!".[16] The 1987 turtles also had a crossover with the 2012 turtles in the season 4 episode, "Trans-Dimensional Turtles". In addition with the lead cast-members reprising their roles from the episode, Pat Fraley also reprised his role as Krang, who is depicted as a relative of Kraang Subprime.[17]

In 2017, during season three of the Nickelodeon series, another crossover between the MWS series and the Nickelodeon aired. It had three parts.

Soundtrack
Through most of the series, the episodes featured a recurring background music which reflected the mood of the situation, as well as ID music for settings such as the Technodrome, the New York City sewers, Channel 6, etc.. The soundtrack was composed by Dennis Challen Brown (credited as "D.C. Brown" and later as "Dennis C. Brown") and Chuck Lorre. Lorre recorded the theme song (and performed the spoken parts) and became a successful television producer. The performer of the song was James Mandell (aka Miles Doppler).[18] To date the soundtrack has never been released for retail.

The Channel 6 News theme music also appeared in the Turtles in Time video game.

Voice acting
Casting for the show took place in Los Angeles. During recording of the voice acting, all the main cast recorded together. According to Renae Jacobs, voice-actress of the reporter April O'Neil, working together "was great for camaraderie and relationships. We played off each other...there was a lot of ad libbing."[19]

Also according to Jacobs, the actors frequently undermined the efforts of the show's creators to make the show grittier and more serious, instead embracing silliness and jokes for both children and adults.[19]

Teenage Mutant Ninja Turtles

 * Leonardo (voiced by Cam Clarke) – The blue-masked turtle who wields two katana. He is the leader and commander of the Turtles and is the closest to Splinter. He is also the oldest of the his brothers most serious, level-headed member of the team, who values his leadership.
 * Donatello (voiced by Barry Gordon in most episodes, Greg Berg in six Season 3 episodes and one episode of the European side-season) – The purple-masked turtle who wields a bō staff. He is the scientist and intellectual of the team who is constantly tinkering with various inventions. Donatello's capabilities in science and technology have been key factors for the Turtles' successes in their battles with Shredder and other villains.
 * Raphael (voiced by Rob Paulsen in Season 1-9, Thom Pinto in two Season 3 episodes, Hal Rayle in the European side-season, and Michael Gough in Season 10) – The red-masked turtle who wields two sai. Although Raphael is depicted as an angry, impulsive hothead in most other TMNT media, in the 1987 series he is the comedian of the team who often comes out with sarcastic and witty remarks. He provides comic relief for the show, constantly breaking the fourth wall.
 * Michelangelo (voiced by Townsend Coleman) – The orange-masked turtle who wields a pair of nunchakus, which is later changed to a grappling hook. He is the youngest goofy, fun-loving "party animal" of the team who often speaks in surfer slang, and is the source for many of the show's catchphrases, such as "Cowabunga!". More so than any other Turtle, he is obsessed with pizza and enjoys experimenting with various toppings, even when the other Turtles find it gross. He is also considered to be the least intelligent member of the team, especially by Raphael.

Allies and friends

 * Hamato Yoshi/Master Splinter (voiced by Peter Renaday in most appearances, Townsend Coleman in two Season 5 episodes) – A strict and wizened sensei who used to teach Oroku Saki, until the latter set him up for an offense towards his master which he did not commit and was exiled from the Foot Clan. Since then, he has lived in the sewers of Manhattan as a homeless man, with the rats and his four pet turtles as his only friends. Upon being exposed to the same mutagen that changed the turtles into their present anthropomorphic forms, Hamato Yoshi transformed into a humanoid mutant rat (as he had most recently been exposed to rats) and trained the Turtles in ninjutsu. It is later revealed that one of his distant ancestors is the founder of the Foot Clan.
 * April O'Neil (voiced by Renae Jacobs) – A red-headed TV reporter from Channel 6 News (later a freelance reporter in Seasons 9 and 10) who discovers the Turtles' home in the sewers and befriends the TMNT. She is frequently kidnapped by Shredder and other villains, usually as bait to lure the Turtles out of hiding.
 * Irma Langinstein (voiced by Jennifer Darling) – Channel 6's clumsy, dating-obsessed secretary who debuts in season 2. She is a friend of April who later also befriends the TMNT. Following the destruction of the Channel 6 Building in season 8, Irma is slowly phased out of the show. A similar character would by used in the 2012 series.
 * Casey Jones (voiced by Pat Fraley) – A violent, impulsive, and overzealous street-fighting vigilante who is friends with the Ninja Turtles. He fights using sports equipment and wears a hockey mask.
 * Zach the Fifth Turtle (voiced by Rob Paulsen) – A 14-year-old teenager who looks up to the Turtles and is their biggest fan.
 * Caitlin (voiced by Maggie Roswell) – A female teenage friend of Zach.
 * Aunt Aggie (voiced by Joan Gerber) – April's detective aunt who occasionally helps the Turtles defeat their enemies. She also runs a popular crime TV show.
 * The Punk Frogs – The mutant frog counterparts of the Teenage Mutant Ninja Turtles who were accidentally mutated by Krang (as the portal he had used to send his last remaining batch of mutagen to Shredder was unstable at the time, causing it to land in a swamp somewhere in Florida, where it transformed four frogs, who had most recently been in contact with a human boy, into their present forms) and trained in martial arts in the hopes that they would be a match for the Turtles. Further emulating his rival Splinter, Shredder names the four frogs after his own personal heroes: Attila the Hun (Attila the Frog), Genghis Khan (Genghis Frog), Napoleon Bonaparte (Napoleon Bonafrog), and Grigori Rasputin (Rasputin the Mad Frog). Despite their innocent, docile nature, they are also extremely naive, and as such, they were easily misled by Shredder into believing that the Turtles were "evil" and that Shredder was a "good person". However, they eventually turned against Shredder and became allies of the Ninja Turtles. The frogs all speak with southern accents.
 * Attila the Frog (voiced by Townsend Coleman) – A Punk Frog that is armed with a mace.
 * Genghis Frog (voiced by Jim Cummings) – A Punk Frog that is armed with an axe.
 * Napoleon Bonafrog (voiced by Pat Fraley) – A Punk Frog that is armed with a whip.
 * Rasputin the Mad Frog (voiced by Nicholas Omana) – A Punk Frog that is armed with a bow and an arrow.
 * The Neutrinos – An alien race of teenagers from Dimension X whose only goal in life is to have fun.
 * Zenter and Grizzla (voiced by Rob Paulsen and Jennifer Darling respectively) – The leaders of the Neutrinos.
 * Dask (voiced by Thom Pinto)
 * Kala (voiced by Tress MacNeille)
 * Zak (voiced by Pat Fraley)
 * Muckman and Joe Eyeball (voiced by Townsend Coleman impersonating Jackie Gleason and Rob Paulsenimpersonating Art Carney respectively) – Garson Grunge and Joe Junkee are two garbage men who were mutated by a substance poured out of a window by Bebop and Rocksteady. Garson mutated into a man-shaped garbage creature while Joe mutated into a small green creature with eye-stalks. They mistakenly thought that the Turtles had caused them to mutate, but when the latter were found innocent, Muckman & Joe Eyeball helped them rescue Splinter from the Technodrome.
 * Usagi Yojimbo (voiced by Townsend Coleman) – A samurai rabbit and master swordsman from an alternate dimension's 16th century Edo Period Japan where animals are the dominant species on Earth and not the humans. Usagi Yojimbo is a comic book series created by Stan Sakai starring the ronin hero rabbit Miyamoto Usagi which had several crossovers with the TMNT comics. Apparently, the TV show writers did not understand the distinction and misnamed the character after the comic book.
 * Kerma (voiced by Jan Rabson) – A native of the distant utopian planet Shell-Ri-La (the name being a pun on Shangri-La) which is home to a peaceful, but generally defenseless species of humanoid turtles called Turtleoids. He arrives on Earth seeking the Turtles' help in protecting his home planet from various threats. Kerma's voice and personality are extremely similar to that of Jiminy Cricket.
 * Bugman (voiced by Dan Gilvezan) – Brick Bradley is a scientist who got caught up in a mutant experiment and can now mutate into a large insect when angered. As Bugman, Brick had the eyes, antennae, wings, and extra arms of a fly, and the tail of a scorpion. Michelangelo was a fan of Bugman and first encountered him in "Michelangelo Meets Bugman" where he helped him fight Electrozapper. In "Michelangelo Meets Bugman Again", Michelangelo and Bugman faced off against the Swatter.
 * Mona Lisa (voiced by Pat Musick) – A college girl who is a physics major that was captured by Captain Filch so that he can have her help in his experiments. While trying to destroy his nuclear reactor, Mona Lisa was turned into a mutantlizard. She appeared to be romantically interested in Raphael and appears in "Raphael Meets His Match". Although she followed the Turtles back to New York at the conclusion of the same episode, she is not seen again afterwards.
 * Buffy Shellhammer (voiced by Jennifer Darling) – The bratty 15-year-old teenage director of Shellhammer Chemicals. She was kidnapped by Bebop & Rocksteady in order to get a formula for rocket fuel needed to free the Technodrome. Their plans were foiled by the Turtles.
 * Rex-1 (voiced by Jack Angel) – A robot police officer built to keep crimes out of the city.
 * Carter (voiced by Bumper Robinson) – Introduced in season nine, he travels to New York City to study martial arts under Splinter, but is accidentally exposed to a mutagen which causes him to spontaneously oscillate between his human and mutant forms. He was an important ally to the TMNT in their battles against Lord Dregg. In season 10, he temporarily leaves to finish his studies after Donatello stabilized his mutation, although he returns upon learning from April that the Turtles were captured by Lord Dregg, Krang, and Shredder. While on his way to rescue the Turtles, Carter found that he could still mutate. At the end of "Turtles to the Second Power", Carter accepts Landor and Merrick's offer to travel with them to the future so he can be fully cured of his mutation.

Antagonists and villains
The Shredder, as seen in the series' opening theme sequence, and some Foot soldiers.
 * Foot Clan
 * Oroku Saki/Shredder (voiced by James Avery in Season 1 to the first half of Season 7, Dorian Harewood in four Season 3 episodes, Jim Cummings in one Season 5 episode and most of the European side-season, Townsend Coleman for the second half of Season 7, William E. Martin from Season 8-10) – The nemesis of the Turtles and Master Splinter. He is usually the main villain in other media, but in this series Shredder always, against his will, has to take orders from Krang, although their relationship evolves over time into more of an equal partnership (with Shredder even risking his life to save Krang on numerous occasions). His real name is Oroku Saki, a member of the Foot Clan in Japan and a student of Hamato Yoshi/Splinter. Saki was jealous of Yoshi's leadership within the Clan and sought to usurp him. He responds by framing Yoshi for an offense towards the sensei and has him exiled. Shortly afterwards, Saki takes control of the Foot Clan and transforms it into an army of crime under his command. Along with Krang, Rocksteady, and Bebop, he is the primary antagonist of the show until the end of season 8, when the Technodrome is destroyed and they are all banished to Dimension X. Although he and Krang return for 3 episodes in the final season, they are eventually sent back to Dimension X, and they are not seen again for the rest of the series. Their fate after being transported back to Dimension X is unexplained, although it is assumed that they would have eventually perished or found their way back to Earth.
 * Rocksteady (voiced by Cam Clarke) – Rocksteady is one of Shredder's incompetent, oafish henchmen. Originally a Caucasian male member of an unnamed street gang, Rocksteady was exposed to the mutagen after coming into contact with a black rhinoceros that was stolen from the zoo, transforming him into a humanoid black rhinoceros. Like Bebop, he is extremely unintelligent (although he is shown on multiple occasions to be slightly more intelligent than Bebop) and serves as a comic relief for most of the series.
 * Bebop (voiced by Barry Gordon in most episodes, Greg Berg in six Season 3 episodes and one episode of the European side-season) – Bebop is an African-American male with a mohawk, sunglasses, and a nose ring who, along with Rocksteady, is one of Shredder's henchmen. Prior to meeting Shredder, he belonged to the same street gang as Rocksteady. As part of Shredder and Krang's experiment, he was transformed into a humanoid common warthog after being exposed to the mutagen and a common warthog that was stolen from the zoo.
 * Baxter Stockman (voiced by Pat Fraley) – Baxter Stockman is a blond Caucasian inventor (as opposed to the dark-haired African-American he was portrayed as in the Mirage comics; it is generally assumed that his race was changed out of fear that portraying him as a black man, ordered around and frequently subjected to verbal abuse by Shredder, would be seen as politically incorrect) who tried to bill his rat-catching Mousers to the Ajax Pest Control company. They did not like his suggestion, saying it would put them out of business (since the Mouser was so effective that it would eliminate all of the rats in the city) and threw him out of the building. Embittered, he readily agrees to join forces with Shredder, who orders him to replicate his Mousers and hunt down Splinter. After the Ninja Turtles defeated the Mousers, Baxter Stockman was arrested and thrown into an asylum. Shredder later broke him out, and Baxter Stockman became Shredder's lackey, helping him to get the "Three Fragments of the Eye of Sarnath" (an alien artifact that would grant the owner virtually limitless power). Shredder later traded Baxter Stockman to Krang for the return of Bebop and Rocksteady. When Krang found no use for Baxter and decided to kill him, a fly that had been with Baxter in the disintegrator unit soon merged with him, turning him into a humanoid fly. He has occasionally plotted revenge against the Ninja Turtles and Shredder. Baxter Stockman has a twin brother named Barney who was also a mad scientist and threw fits whenever the Turtles mistook him for Baxter.
 * Z (voiced by Townsend Coleman) - The spaceship computer found on an abandoned spaceship that allied with Baxter Stockman where it assisted him in his plots in "Bye, Bye, Fly," "Son of Return of the Fly II," and "Revenge of the Fly."
 * Foot Soldiers – A group of robotic ninjas that serve as Shredder's loyal soldiers.
 * Alpha One (voiced by Jim Cummings) – A Foot Soldier who had his intelligence increased by Krang and Shredder.
 * Krang (voiced by Pat Fraley in most episodes, Townsend Coleman in two Season 3 episodes) – An extremely intelligent, disembodied brain from Dimension X who commands the Technodrome. Like Shredder, he aspires to conquer the Earth, although he does not share Shredder's obsessive hatred of the Turtles and Splinter (instead viewing them as more of an annoyance/obstacle), preferring instead to focus on world conquest. He funds and helps plan most of Shredder's schemes, although they often bicker with one another over tactics. In season 7, it is revealed that Krang originally belonged to a muscular, vicious reptilian species (mainly resembling a T-Rex) with regenerative powers before he lost his body and was banished from Dimension X.
 * Rock Soldiers – The Rock Soldiers are an army of sentient rock humanoids from Dimension X. As mentioned in "Michelangelo's Birthday," the Rock Soldiers were created when Krang used mutagen on some rocks. The Rock Soldiers are incredibly strong, but they are not very bright.
 * General Traag (voiced by Peter Renaday) – Traag is a Rock Soldier general that is loyal to Krang.
 * Sergeant Granitor (voiced by Pat Fraley impersonating Peter Lorre) – Granitor is a high-ranking gray Rock Soldier that is loyal to Krang and works under General Traag.
 * Rat King (voiced by Townsend Coleman) – Rat King is a homeless man living in a dilapidated portion of the New York City sewer system, not too far from the Turtles and Splinter. In episodes featuring him, the Rat King would often enact some sort of plot to establish his own rat-controlled government and bring human rule to an end, believing that rats (which he counted himself as) were superior to all other species, whom he described as "inferior non-rodents". He appears as a recurring villain from season 3 onwards, until he is finally apprehended by the police in the second episode of season 8.
 * Leatherhead (voiced by Jim Cummings in most appearances, Peter Renaday in "Night of the Rogues") – Leatherhead is a large alligator who had mutated into humanoid form when he swam through a Mutagen-polluted part of the swamp. He hunted the Turtles' allies the Punk Frogs, and then went to New York to hunt the Turtles themselves. His final appearance is in "Night of the Rogues" in season 7, in which he (along with other recurring villains) is recruited by Shredder to help him fight the Turtles. His fate is not clearly known, but it is assumed that he has long since returned to the Florida swamps.
 * Slash (voiced by Pat Fraley) – Slash was an ordinary turtle from Earth that was mutated by Bebop and Rocksteady. He is a muscular, vicious humanoid turtle with brute strength and surprising agility, but very low intelligence (although he does temporarily acquire a genius level IQ in his second appearance). He is extremely attached to the small, plastic palm tree that stood in his bowl prior to being mutated, and calls it his "binky".
 * Metalhead – A robot turtle that was created by Shredder. He has numerous voice's that sound like any of the turtles and has a laser gun installed in his chest. He can also fight by extending his arms and legs. Sometimes, he'd malfunction and attack Shredder and his goons other than just the turtles.
 * Pinky McFingers (voiced by Peter Renaday in most appearances, Cam Clarke in "Donatello's Duplicate") – Pinky McFingers is a high ranking mafia boss with a gang at his disposal. McFingers once sponsors Baxter Stockman's twin brother Barney Stockman to create a "gag-a-magnifier" device that increases the comedy power of jokes. They planned to hook up the funniest comedian to it and transmit the joke waves all over the city, making everyone hysterically helpless. This enabled McFingers and his two goons would go out and rob the city. He and his men kidnapped comedians until they kidnapped Raphael. They tied Raphael up in a sack and took him to their hideout where strapped down, McFingers tells him of his brilliant plan. Being the funniest comedian, Raphael is forced to start telling his jokes. However the rest of the turtles rescue him and the other comedians and turn the devise against Stockman and the McFingers gang, all of whom end up arrested.
 * Big Louie (voiced by Peter Renaday) – Big Louie is a Godfather-like high ranking gangster with a gang at his disposal, who sometimes works with the Shredder. He's fighting a turf conflict against another gangster group led by Beaver "Babyface" Cleaver and Wally Cleaver.
 * Don Turtelli (voiced by Peter Renaday) – Don Turtelli is the head of the crime syndicate. He is the grandson of Tony "The Tickler" Turtelli. Turtelli went down in infamy for his torture methods, which he inherited from his grandfather. He specializes in the interrogation of people he captures through tickle torturing the soles of his victims' feet with a feather to make them talk.
 * Dr. Polidorius (voiced by Alan Oppenheimer) – A mad scientist who created the mutant humanoid fish Ray.
 * Ray (voiced by Pat Fraley) – A humanoid fish created by Dr. Polidorius to serve him and assist with his plans to destroy the city.
 * Wingnut and Screwloose (voiced by Rob Paulsen and Townsend Coleman respectively) – An alien bat and an alienmosquito who brainwashed kids at a military school to help them invade the earth.
 * Groundchuck (voiced by Robert Ridgely) – A mutant red bull in cyborg armor that was accidentally created by Bebop and Rocksteady.
 * Dirtbag (voiced by Pat Fraley) – A mutant mole that was accidentally created by Bebop and Rocksteady.
 * Chrome Dome (voiced by Peter Renaday) – A huge robot built by Shredder to supervise the Foot Soldiers into building the Technodrome Mark II. The Turtles defeated him by disabling the chip on his back. In "Night of the Rogues," Chrome Dome was reactivated where he is among the villains that helped Shredder and Krang attack the Turtles. He is defeated when Casey Jones crushes him with a hydraulic press.
 * The Swatter/Jerry Spiegel (voiced by Townsend Coleman) – A comic book artist who attempted to steal the Turtles' secrets and publish them to the world only to run afoul of them and Bugman.
 * Professor Filo Sopho (voiced by Rob Paulsen) – The head of Sopho University who first attempted to speed up the Earth's rotation in "Donatello's Degree." In "Too Hot to Handle," Professor Sopho tried to move it closer to the sun creating uninhabitable conditions for humans.
 * Shreeka (voiced by Joan Gerber) – Krang's former partner in crime who returns in "Shreeka's Revenge" to reclaim the "power ring" that Krang stole from her.
 * Professor Cycloid (voiced by Hamilton Camp) – A crazed professor who stole Donatello's "time stopper" machine in an effort to take over the world.
 * Tempestra (voiced by Gaille Heidemann) – Tempestra is a powerful weather-controlling sorceress who came from a video game that she got out of during a thunderstorm. In "Night of the Rogues," Tempestra was among the villains that helped Shredder and Krang attack the Turtles.
 * Scumbug (voiced by Barry Gordon) – A mutant cockroach who was among the villains that helped Shredder and Krang attack the Turtles. He was one of the few villains from the Archie Comics series "Teenage Mutant Ninja Turtles Adventures" to appear in the cartoon where the comics revealed that was mutated from an exterminator that came in contact with a cockroach in the Technodrome.
 * Antrax (voiced by Pat Fraley) – An alien ant who works as Krang's executioner. In "Night of the Rogues," Antrax is among the villains that helped Shredder and Krang attack the Turtles.
 * H.A.V.O.C. – Short for Highly Advanced Variety Of Creatures, H.A.V.O.C. is a gang of mutants. The Turtles meet H.A.V.O.C. in the process of thwarting a robbery, meeting mutants and H.A.V.O.C. members Raptor, Amok, and Overdrive, and then later, the H.A.V.O.C. leader, Titanus. The Turtles find out that while H.A.V.O.C. has offered the Turtles a safe haven from those who think they are the villains, H.A.V.O.C. is actually creating mutants instead of protecting them and actually tries to turn the entire city into mutants. The Turtles spend a few episodes of season 8 battling H.A.V.O.C. After they get rid of the boss, none of the other mutants appear again.
 * Titanus (voiced by Ron Feinberg) – A large mutant from the future who is the leader of H.A.V.O.C. In his final appearance, he ends up trapped in the time of dinosaurs, and vows to have revenge against the Turtles if it is the last thing he ever does.
 * Amok (voiced by Townsend Coleman) – A mutant goat.

In H.A.V.O.C. in the Streets, Titanus breaks him out of jail and turns him into an electric mutant. Synapse keeps the Turtles busy for a while until Donatello forces him through a ham radio, leaving him trapped on the radio airwaves forever.
 * Lord Dregg (voiced by Tony Jay) – An alien warlord who appears as the chief antagonist for the final 2 seasons of the series, following Shredder and Krang's exile to Dimension X in season 8. At the end of the final season, Lord Dregg is banished to Dimension X as well (and is presumably killed, since the Turtles had sent Krang's android suit back with him as it was about to undergo an atomic explosion). Although he starts out as a cold, calm, and calculating villain, his sanity gradually deteriorates over the course of season 10, as he becomes increasingly obsessed with destroying the Turtles once and for all. In the process, he alienates all of his remaining followers, including his second-in-command Mung, who accuses him of losing sight of their quest for world domination.
 * HiTech (voiced by Rob Paulsen in Season 9, Cam Clarke in Season 10) – An insect-like alien in high tech armor who is Lord Dregg's second-in-command. When Mung proves more efficient as second-in-command, Lord Dregg blasts HiTech off in a pod to "orbit the galaxy".
 * Mung (voiced by Cam Clarke) – A hunchbacked beetle-like henchman of Lord Dregg who replaced HiTech in the final season. He is a technical and mechanical genius where he surpasses HiTech.
 * TechnoGang – A gang of insect-like foot soldiers that serve Lord Dregg.
 * Batmen – A group of ugly winged humanoid that serve as the alternate foot soldiers for Lord Dregg.

Other characters

 * Channel 6 News Staff – The workers of Channel 6 News that often have involvements with the Ninja Turtles. Following the destruction of the Channel 6 News building during Season 8, these characters slowly faded out of the show. The old Channel 6 building also made a cameo appearance in the crossover movie Turtles Forever as the 2003 Turtles take a detour in the dimension of their 1987 counterparts.
 * Burne Thompson (voiced by Pat Fraley in most episodes, Townsend Coleman in three episodes of Season 3) – April's boss at Channel 6 News. Like J. Jonah Jameson, he believed the Turtles were a menace and encouraged April to expose them. His hatred for the TMNT intensified following the destruction of the Channel 6 building by Shredder in season 8, an incident he blamed on the Turtles. He often favored Vernon more, which was likely due to the fact that Vernon shared Burne's distrust of the TMNT and did not hesitate to cast a negative light on them in his news coverage. In the 2014 TMNT film, a female adaption of this character named Bernadette Thompson was used, who was portrayed by Whoopi Goldberg.
 * Vernon Fenwick (voiced by Peter Renaday) – April's cameraman and rival news reporter. In season 1, he had more of a serious and dedicated personality, although shades of the cowardice and rivalry with April that would define Vernon's character throughout the rest of the series would sometimes surface. From season 2 onwards, he was written as a selfish, egotistical, opportunistic, and cowardly cameraman and co-reporter who would often go to great lengths to steal April's thunder, although he was quick to cede all of the more "dangerous" assignments to April, not willing to put himself in harm's way. Like Burne, he strongly believed that the Turtles were a menace to society and often actively participated in Burne's anti-mutant campaigns, even though the Turtles had saved his life on many occasions. Vern appears in the 2014 TMNT film and its 2016 sequel portrayed by Will Arnett. However, this version of the character portrays him in a far more positive light as he is the secondary protagonist who has a not-so-secret crush on April, but she remains oblivious.

International broadcasting

In the United Kingdom, TMNT was released under the name Teenage Mutant Hero Turtles (TMHT). This was due to Prime Minister Margaret Thatcher, the controversy surrounding ninjas and related weapons such as nunchaku at the time.[21] The intro sequence was heavily edited because of this, replacing the word ninja with hero orfighting, using a digitally faded logo instead of the animated blob, and removing any scenes in which Michelangelo wields his nunchaku, replacing them with random clipsfrom the show with the weapon the grapple tortoiseshell.[22]

The TMHT version was aired in other European countries, including Ireland (except series 1, which had the original title), Belgium, Germany, Austria, Poland, Hungary, Sweden, Norway, Denmark, and Finland, in local dubs (the Finnish version was in English with subtitles, while Polish was in English with a voice-over translation). In Denmark, the English censored version was aired on the national broadcaster TV2. It had subtitles as well, however, only seasons 2 and 3 were aired in this fashion. Season 1 was aired as one spliced feature, instead of the original five-part miniseries. The movie was titled The Epic Begins, and included heavy edits from each of the five episodes, and was also released to VHS in the USA in 1988.[23]

After the 2 seasons had aired on Danish TV, the show was cancelled; however, it later returned with local dubs of episodes from season 5, and Denmark was also one of the first countries to get to see the episodes in which the turtles travel to Europe. These were also aired with subtitles.

The original series aired in early 2011 during the early morning hours on TV2 in Denmark. All 193 episodes have been re-dubbed, and this time they aired in their original US unedited form.

In Spain, the name of the cartoon was translated to Las Tortugas Ninja (with the word ninja in the title), but at first the TMHT version was still used for dubbing, although the word ninja was kept in several instances of the dub, and the original TMNT version was also alternatively aired afterwards. Other European countries (including Bulgaria, France, Italy, Russia, Serbia and Turkey) dubbed the original TMNT version.

In Ireland, the series was initially known as Teenage Mutant Ninja Turtles and the intro sequence was unedited when it debuted with the airing of the second season. After the first two episodes were broadcast, the name was changed toTeenage Mutant Hero Turtles and the intro was edited, except for season one. In 2007–2008, episodes were aired in their original US unedited form.

When shown on the BBC, phrases like "Let's kick some shell!" and "Bummer!" were removed from the episodes (the latter may relate to a British slang term for anal sex). The series Ninja Turtles: The Next Mutation was also referred to as Hero Turtles, possibly using the term hero to separate the television series from the live action movies. The 2003 television series, however, remained intact when shown in the UK and Ireland. This led the UK and Ireland to have a disambiguation between the two animated series, using Hero Turtles to separate the 1987 television series from the other incarnations of the franchise. In 2009, a DVD of the first two seasons was released under the Ninja Turtles branding, thus bringing this version of the franchise into line with the later versions.

The first season of the show premiered in Australia as a two-part (90 minutes each) prime-time miniseries on the Seven Network, in 1989, before shifting to a 4:30 pm timeslot for Season 2. Later, after ratings fell, it was moved to a morning timeslot on Agro's Cartoon Connection. The show was mostly uncensored, airing under its original name with occasional edits, including the editing of Season 1 into the two-part 90-minute primetime broadcasts. However some "Hero Turtles" branded merchandise was commonly[citation needed] available in the country due to being imported cheaply from the UK.

Reruns
On April 6, 2012 reruns of the series broadcast weekly on Teletoon Retro in Canada until the channel was shutdown on September 1, 2015. There are no other TV reruns of the original Teenage Mutant Ninja Turtles animated series currently airing in North America, due to the series being too old to do reruns of. Although the last episode broadcast on CBS on November 2, 1996, reruns of Seasons 8, 9 and 10 continued to air until August 30, 1997.[24] The series previously reran in North America in Quebec on Super Écran, who rebroadcast the entire series from 2006 to 2008. Episodes from Seasons 1-7 were reran on the USA Network's USA Cartoon Express from September 13, 1993 to September 15, 1996 (which was the last time to date any episode from prior to Seasons 8-10 aired on television in the United States). Lionsgate Home Entertainment and Fred Wolf Films own the rights to the show, and they have been responsible for the DVD releases.

Neither Mirage Studios nor Viacom, the current owner of the franchise, own the rights to the 1987 television series, so Lionsgate and Fred Wolf are not under any obligation to inform them of future releases.[25] Some reruns were shown for UK audiences on BBC weekday mornings (although they were mostly all from seasons two and three). In the Republic of Ireland, the series ended its original run on August 9, 1998,[26] but the show was regularly rerun on RTÉ Two until 2008.[27] InYugoslavia the series was broadcast on RTS from 1991 - 1994 and on RTV Pink from 1998 - 2002. In Denmark, the show is aired every weekday at 6.00 am on TV 2. In Australia, the rights to the show are now owned by Network Ten, and the show occasionally airs on their digital channel Eleven every Sunday mornings at 9am to 10am for double episodes.

Reception
IGN named TMNT as the 55th best show in the Top 100 Best Animated TV Shows.[28] While the story diverged heavily from the original conception of the Teenage Mutant Ninja Turtles with the universe of the original Mirage comics, the 1987 television series is largely the most notable and popular incarnation and drove the franchise to the phenomenal status it would achieve in pop culture. Co-creator, Peter Laird, has publicly shared his distaste with the show on numerous occasions but has also acknowledged that it was extremely successful with and beloved by its audience and, while he would've preferred a different approach to the material, it might not have been as popular as what was produced.[29] Retroactively, the cross-over film Turtles Forever established a common multiverse continuity between all Teenage Mutant Ninja Turtles variations that existed at the time of the 25th anniversary of the original Mirage comicbooks, primarily focusing on this series, and those of the 2003 animated series. Therefore, while not part of the original canon of the Mirage Turtles, the series can be considered part of the wider official turtles canon.

At the time, the series was criticised for its commercialism and violent content.[30][31][32][33][34]

Home video releases
Originally, the series was released to VHS tapes and laserdisc between 1988 and 1996 by Family Home Entertainment while airing back in the late 1980s-early 1990s. Starting in April 2004, DVD releases began.

Region 1
Lionsgate Home Entertainment has released the entire series to DVD in Region 1.[36] Initially it was released in volumes, with each volume containing 9–13 episodes in production order, with the exception of the first volume, which included bonus episodes from the last season. After six volumes, it was announced that the series would now be released in season sets, starting with season 4. However, the episodes "Once Upon a Time Machine" and the 1991 prime-time special "Planet of the Turtleoids" were omitted from the Season 5 set, but are included in the Season 10 set as bonus episodes.[37] The DVDs do not include the Turtle Tips PSAs.

On November 13, 2012, Lionsgate released Teenage Mutant Ninja Turtles - The Complete Classic Series on DVD in Region 1.[38] The 23-disc set features all 193 episodes of the series as well as bonus features. It also contains special collectors edition packaging.

On July 23, 2013, Lionsgate re-released all 47 episodes of season 3 together in a 4-disc box set.[39]

Region 2
The first volume of the 25th Anniversary Edition, containing all episodes from the first two seasons in a PAL format, was released for Region 2 DVDs by Lionsgate Home Entertainment in the UK and Ireland on 25 May 2009.

4 DVDs containing 3 episodes each based around Leonardo, Donatello, Raphael and Michelango were released on 19 May 2014. The series has also been released by German distributor KSM GmbH.

Region 4
The Series is being released in Australia by Lionsgate Home Entertainment. The first six DVD's are more or less duplicated from the Region 1 discs released in America, however unlike the American release Season 4 was broken down into several separate volumes (7 to 9). The discs are in Region 4, but they are in NTSC picture format, instead of PAL, reflecting the changes in television technology since the original airing of the series in 1990. The released episodes reflect the series initial Australian broadcast in its late afternoon timeslot. Later episodes from when the show was shifted to a morning timeslot (due to declining popularity), have yet to be released.

Magazine
Teenage Mutant Ninja Turtles Magazine was a children's magazine published quarterly by Welsh Publishing Group, Inc during the height of TMNT popularity in the late 1980s and early 1990s. It was officially licensed by Eastman and Laird and available by subscription.[61]

The $1.95, 32-page magazine featured articles about the Teenage Mutant Ninja Turtles and a variety of other subjects, including an article on the last page of each issue spotlighting a real life turtle species. Mirage Studios staff artists such asDan Berger and Jim Lawson provided a majority of the covers and spot illustrations. A pullout poster was available in every issue and was painted by Mirage Studios artist Michael Dooney.
