Avian

The Avians are fictional humans who were altered by the ancient Y'Lyntian civilization. They were enslaved as guards in order to keep rebellious citizens from escaping. The Avians were forced to live in a giant cage as not to 'befoul the Y'Lyntian air'. Other human tribes rebelled and the Avians joined in. In the process, they transformed their prison into a home with the assistance of several pieces of an object called the Crystal Sun.

This place lasted for thousands of years, hidden high above the clouds. It could only be located with a similar crystal. Unfortunately, one of the Avians, Mephos, soon believed they should rule over the surface world. Mephos sparked a civil war, which fortunately ended with his capture. The Avian Council then sentenced Mephos to exile on the surface, stripped of his wings.

Bio Mouser

In 2055, the EPF used the genetics of captured aliens to create a more biological form of the mechanical Mouser. These creatures could be controlled by sound and had excellent stamina. This project was supervised by Agent Bishop and Baxter Stockman. However, in a cascade failure, the mouser went out of control, destroying the lab and Stockman was possibly killed.

50 years after the accident, Stockman once again rose from the wreckage as a brain with one eye and tentacles. He used his Mousers to capture Bishop, who had become president of the Pan-Galactic Alliance so he could be his new body. Donatello managed to find the sonic frequency that controlled the Mousers, once again setting them on a rampage, destroying an abandoned EPF lab. They were then used for farming.

Brotherhood

The Brotherhood are a lizard-like species living in an alternate dimension that appeared in the episode "Trouble with Augie". The Brotherhood are an extremely vicious race, who wiped out all life on their own world and now travel to alternate ones simply to feast on the inhabitants. Unfortunately, the gateway in the last world they reached was broken, and they were trapped there until April's uncle August arrived. They tricked him into repairing the portal, saying that they simply wished to share their tecnology and knowledge with Earth. Their evil nature was exposed by Donatello before August finished repairing the portal, and the Turtles trapped the Brotherhood leader and several soldiers in a dimension inhabited by giant carnivorous insects. The rest of their race are still trapped in the previous dimension, starving.

Channel 3

Channel 3 is the TV channel for which April O'Neil works as an investigative reporter in the first TMNT movie. During one of her stories, she gets too close to uncovering the Foot Clan, leading Shredder to send his Foot Ninjas after her. They knock her out in the ensuing scuffle, and Raphael -- who'd been tailing her to retrieve his sai -- intervenes and fights them off before bringing her to the Turtles' lair.

Channel 6

Channel 6 is the fictional TV channel in New York City for which April O'Neil works as a news reporter in the 1987 TMNT cartoon and the Teenage Mutant Ninja Turtles Adventures comics. The news studio is located in a building with a big 6 on it.

Besides April, the known staff of Channel 6 are Burne Thompson, the boss of the station, Vernon Fenwick, a reporter who rivals with April and tries to steal her stories, and Irma Langinstein, a secretary.

In the episode Get Shredder! [1], The Shredder placed an explosive device in Channel 6's basement and trapped April, Irma, Veron, and Burne in one of the offices. He then forces the Turtles to trade for Krang, whom he believes they have captured (although in reality, Krang was seized by Drakus; a former friend and the original designer of the Technodrome who Krang sold out years ago). Although the Turtles were successful in rescuing Krang, Shredder still blew up the building. Fortunately, Splinter was able to free the hostages before the building exploded. Burne Thompson blamed the Turtles for the destruction of the Channel 6 building, and as a result the Turtles became wanted outlaws. The Channel 6 crew moved to a smaller building. In season nine, April had become a freelance reporter and the crew of Channel 6 was never seen again for the remainder of the series.

In the 2003 TMNT episode "Secret Origins Part 3," April (complete with yellow jumpsuit) pretends to be from "Channel 9", then says "Channel 6" when the fake nine on her costume turns upside-down.

C.R.A.P./ H.A.T.E.

File:TMNT310EpisodeGuide.png

A H.A.T.E. rally.

C.R.A.P., short for Committee to Rebuild American Patriotism was a group of extremists encountered by the Turtles, April, Casey and Splinter during their stay in Northampton. C.R.A.P., led by a man named Skonk, had planned on using a nuclear bomb they had gained possession of to fake an attack by Russia, hoping that the bomb would spark World War 3.

Unfortunately for C.R.A.P., the physics student they had kidnapped in order to prepare the bomb had managed to escape. Encountering the student, revealed to be named Michael, the Turtles learned of what C.R.A.P. was planning and set out to stop the group while the recently shot Michael was brought to a nearby hospital.

After doing battle against C.R.A.P.'s thugs and defeating them, the Turtles found themselves too late to stop Skonk, who planned on detonating the bomb at C.R.A.P.'s compound. It was only after detonating the bomb that it was revealed that Donatello had removed the bombs plutonium; without its core, the bomb created only a small-scale explosion which blew up the C.R.A.P. compound, killing Skonk. With the death of their leader, what was left of C.R.A.P. disbanded and left.

In a TV adaptation of the original “The Survivalists” story, C.R.A.P. was replaced by H.A.T.E. (Humans Against The Extraterrestrials), an extremist group formed after the Triceraton invasion in order to defend Earth against further alien attack. Believing (based on tabloid retellings of the turtles exploits) that aliens still inhabited Earth and were using New York City as a base, H.A.T.E.’s aim was to wipe the city with a nuclear bomb. Like the comic, the Turtles stopped their plan and left their leader tied up with a plutonium core on his person.

Dark Turtles

A group of clones of the turtles from the Fast Forward series. Created by Sh'Okanabo and used by Darius Dun, these clones are allegedly stronger and more merciless than the originals. They are voiced by the regular turtles' voice actors.

D.A.R.P.A.

D.A.R.P.A., short for either Defense Advanced Research Projects Agency or Defense And Research Projects Administration is a discreet branch of the CIA which deals with supernatural and otherworldly matters. Operating chiefly out of Nevada, DARPA was first briefly seen in Volume One of the Teenage Mutant Ninja Turtles and was featured more prominently in Volume Two of the comic.

Some of the activities performed at DARPA include the capture, study, and presumed dissection of extraterestrials and mutations, making alien technology backwards-compatible, and performing somewhat inhumane experiments on humans and other creatures.

Doom Bears

A quartet of not-so-cuddly bears featured only in the TMNT role playing game, each possesses an insignia on his chest in a parody of Care Bears. The roleplaying game suggested that they had escaped from a cruel scientific research facility.

The bears have psychic powers that allow them to instill emotions in other creatures based on their insignias. The bears are:

Fear Bear - his chest displays a twisted evil skull with spider features. Can terrify his victims.
Pain Bear - his chest displays a skull with thorns bursting from it. Can cause horrible pain.
Doom Bear - his chest displays a skull with a mushroom cloud erupting from it. Causes victims to experience horror of a nuclear explosion.
Anger Bear - his chest displayed a flaming skull - possibly made other creatures attack each other.

Although most of the villains from the role playing game were adapted from the original comic series, these characters never appeared in an actual storyline.

Earth Protection Force

A secret organization, formed by President Ulysses Grant and led by Agent Bishop, whose job is to protect Earth. They exist as a black-ops unit. However, due to the lack of alien attacks and numerous "screw-ups," the EPF was at risk of being shut down. Bishop engineered a false invasion to prove his organization's worth and receive funding. However, the false aliens' genetic residue came in contact with local wildlife, mutating them into a more savage, near-sentient form. The EPF and the Turtles used a lot of effort to contain the outbreak but had little success. With Leatherhead's help, the EPF were able to come up with an antidote, which they dispersed all over New York.

Pan-Galactic Alliance

50 years before 2105, the EPF began using the genetics of captured aliens to create a bio army called the Bio Mouser by Baxter Stockman. However, he accidentally caught a genetic failure which resulted in the lab falling apart. Bishop was saved by an alien captive in the confusion, changing his attitude towards aliens. Over the better course of the 21st century, Bishop protected Earth from aliens by making them allies, forming the Pan Galactic Alliance, an organization dedicated to peace throughout the universe with him as its president. PGA headquarters is located in New York where weapons except ones used by guards, are immediately disabled.

Grybyx

Grybyx (pronounced ger-bics, singular and plural) are animals found in Dimension X. They appeared in the 1987 TV series. They have telekinetic abilities and if fed in the incorrect manner they become giant monsters (similar to the Mogwai in the Gremlins movies). Getting them wet will return them to their normal state. They are owned by citizens of Dimension X as pets (equivalent to dogs or cats).

Kala owns a Grybyx.

Federation

File:TMNT2003 Federation.png

Federation troops

Humanity in the other side of the galaxy has built up a large and prosperous empire, despite being one of the youngest and weakest races in biological terms. The Human Federation is actually not a democracy as its name would suggest, but a military dictatorship. The former government steadily gave more and more power to the military due to neighboring races' threats until it had finally taken over in all but name. The Triceratons were the main threat. The Federation has some of the largest borders and frontiers of all the intelligent races in the galaxy, due to colonization and alliances. They are ready to make treaties and support other species and as such have actually earned a reputation for being one of the most trustworthy species in all of space. They can also develop technology themselves, a relative rarity.

The Turtles traveled to the border and backwater planet D'Hoonnib in the Sidayon system during their adventure in space. They encounter the Fugitoid Professor Honeycutt, who has developed a device called the Teleportal, which can transport living beings or bombs to other places. When Federation troops appear looking for Honeycutt, the Turtles come to his rescue. After Honeycutt was subsequently captured by the Triceratons, General Blanque led an all-out assault on the Triceraton homeworlds. Honeycutt escapes from both factions with the aid of the Turtles.

Later, the Triceratons invade Earth, believing Honeycutt to be there. The Federation creates a deal with an Earth Agent named Bishop where all aliens would leave Earth alone if he captured the Fugitoid. Honeycutt was captured and torn open to download the teleportal plans from his brain. The Federation fleets proceed to ambush the waiting Triceratons in orbit. Honeycutt manages to upload a virus into the Federation fleet's systems.. Both leaders of the factions were disposed of and the war was ended.the federation leading generals decided to make it a democracy again and restore there former government shortly afterword.

Foot Clan

Guardians

The Guardians are the human allies and defenders of the Utroms, serving as the counterparts of the Foot Clan commanded by the Shredder. The Guardians are traditionally honorable warriors, armed with high tech weaponry and skilled far beyond the levels of the Foot. The common outift of a Guardian is a blue overcoat with black shirt, pants, and boots, as well as the medallion that is the symbol of their order. Guardians also wear sunglasses, and like the Foot were a group of ninjas established when the Utroms landed on Earth.

Among the ranks of the modern Guardians were Hamato Yoshi and his childhood friend Yukio Mashimi. Yoshi was Guardian Prime, but Mashimi was passed over and eventually joined the Foot. However, due to his failure to advance, he was unaware of secret escape pods that allowed the Utroms to escape Shredder's wrath. Yoshi was later hunted down by the Foot, and he died rather than betraying the Utroms.

The Guardians later proved worthy allies of the Turtles, aiding them in battle against the Foot. Due to their disappearance coinciding with that of Splinter, the Turtles sought out the Guardians while looking for him. They found him, and discovered the history of the Guardians and the Utroms. The Guardians later accompanied the Utroms and Professor Honeycutt back to the Utrom homeworld.

H.A.V.O.C.

H.A.V.O.C. stands for Highly Advanced Variety Of Creatures. The Turtles meet H.A.V.O.C. in the 1987 cartoon. H.A.V.O.C. is a group of mutants in New York City. They offered the Turtles a safe haven from humans who think of them as enemies, but the Turtles find out their secret. H.A.V.O.C. isn't protecting mutants but mutating humans, and are trying to mutate the entire city. The Turtles battle them in a multiple episodes of season 8. Members of H.A.V.O.C. include Raptor, Amok, Overdrive, Magma, Highbeam, Seizure and Titanus, who leads them.

Inuwashi Gunjin

In the year 2105, the Inuwashi Gunjin were a team of warrior-brothers, fitted with armour and metal wings. They were employed (and practically enslaved) by Darius Dun to deal with his nephew Cody after he ran off with the Turtles. Although their past is not fully elaborated upon as of yet, it seems that years ago the Gunjin were noble warriors, but were forced to do Darius' bidding through stasis devices on their chests and mind scramblers deep inside their cerebral cortexes. Deep down, they were very reluctant to follow Dun's orders and craved their freedom and lost honor.

During a battle with the Turtles and Cody on the moon, the stasis devices were destroyed. Now free, the Gunjin helped save Cody from a watery grave and left to travel the galaxy.

However, they were later ambushed by a diminutive alien named Aram Zado who desired to acquire any endangered species of warrior. One of them escaped to Earth to enlist the assistance of the Turtles. When they beat Zado, the Gunjin vowed to use his ship to return all of the captives back to their respective homeworlds.

Their name roughly translates to "Golden Eagle Soldiers".

Justice Force

A super-hero team in the Mirage comic books and second animated series (2003). The team was created by Peter Laird. Originally operating decades ago, the disbanded Justice Force reunited briefly when its former members were being kidnapped. In the Mirage comic book, the kidnapper was former member Dr. Dome, who used the Justice Forcers as bait to draw Justice Forcer Battling Bernice from hiding, and thus confess his love for her; however, he instead attracts Ananda, the late Bernice's daughter, who defeats him in short order. In the cartoon version of the same tale, it is Ananda (here, daughter of both Bernice and Dr. Dome) who kidnaps the Justice Force, as revenge on what she saw as the team's role in her mother's death. In both versions, the story ends as the kidnapper feeling contrition for their actions and forgiven by the Justice Force.

It is interesting to note that Laird has mentioned in the past that the character Metalhead is based on fellow Mirage Studios artist Ryan Brown. Due to Brown's vast amount of hair and his fondness for heavy metal music Laird based his character on his friend. Brown also worked with Laird as inker on the cover for the Justice Force's first appearance in Teenage Mutant Ninja Turtles number 15.

A second, modern-day Justice Force also appears in the 2003 cartoon, consisting of several of the series' super-heroes, and appearing to handle large threats such as the Triceraton Invasion. They also appear in the "Lost Season" in the episode Membership Drive to recruit new members and later joined forces with the turtles and their other allies against the forces of Tengu Shredder. They are headquartered in New York City.

The original Justice Force's membership consisted of:

Stainless Steve Steel
Joey Lastic
Metalhead
Battling Bernice
Dr. Dome
Zippy Lad

While the cartoon's modern Justice Force is composed of:

Silver Sentry
Ananda
Metalhead
Chrysalis
Tsunami
Nobody (joined during Membership Drive)
Raptarr (joined during Membership Drive)
Nano (joined during Membership Drive)
Turtle Titan (part-time)

Kanabo

The Kanabo are a conquering species that goes around the universe and infests planet by planet. Their leader is known as Sh'Okanabo who plans to unleash the his kind on Earth at the "Day of Awakening", when he uses his "gene seeds" that overtakes any all individuals and conquer the planet. However, due to Earth's unique orbit around the sun, the Kanabo cannot survive on Earth during the day. After a recent destruction of a time window, most of the original gene seeds were almost destroyed. Sh'Okanabo took what seeds he had left to Moonbase Bishop, where he took over the place. He planned to use Earth Atmospheric shield that enable how much sunlight the planet gets, to completely darken it. However, the Turtles were able to stop his plan and killed him through use of a solar grenade. They bear some similarities to the Black Arms from Shadow the Hedgehog. In fact, along with having the same voice actor, Sh'Okanabo has many similarities to Black Doom.

Kanabo technology is far more advanced that anything known in the universe. They are capable of enhanced cloning and correcting time windows. However, not even their enhancements can move an entire planet through time.

Kunoichi

The Kunoichi are the female ninja minions of Pimiko.

Malignoids

A race of evil humanoid insects from the Teenage Mutant Ninja Turtles Adventures series. Ruled by a queen named Maligna, they float through space on their Hiveworld seeking out green planets to devour.

Merman

File:TMNT403EpisodeGuide.png

A Mermaid caring for her eggs.

Somewhat bizarre looking race of amphibian humanoids; the Turtles first encounter Mermen while on a raft trip, when they see a female Merman (Mermaid?) crawl ashore and promptly die of radiation poisoning. The Turtles were inspecting the body when they were attacked by a group of Mermen. They believed that the Turtles had slain the female. After learning that the Mermaid had died of an illness instead of being murdered, the group of Merman took the body of their fallen friend and went back to where they came.

Much later, Leonardo encounters another Mermaid named Rhanna, oddly, in the New York sewer system. Engaging Rhanna and her pet, a giant turtle named the "Terrorpin" in combat, Leonardo was forced to kill the pair.

Merman and Mermaids also appeared in the episode Sons of the Silent Age in the 2003 Teenage Mutant Ninja Turtles animated series. The animated series also gave an origin to the Merman, revealing that they, along with the Avians were created to be a slave race to the Y'Lyntian Empire.

Mokusai no Bushi

A group of fighters dispatched by the Ninja Tribunal to capture specific warriors for their test. The Mokusai no Bushi are in actuality inpachi - puppets made from chunks of wood. Their name roughly translates to "Warriors of Wood".

Mutanimals

The Mighty Mutanimals (portmanteau of mutant and animals) were a team of fictional mutants composed of Mondo Gecko, Ray Fillet, Leatherhead, Dreadmon, Jagwar, and their fellow sentient animal-like heroes Wingnut and Screwloose. However, Wingnut and Screwloose are not mutants, they come from the fictional planet Huanu.

Mirage Studio's Ryan Brown and Steve Murphy created the team by bringing together their animated television show characters and Playmates toy action figure creations. The Mighty Mutanimals first appearance was in issue 19 of the Teenage Mutant Ninja Turtles Adventures title published in April 1991 by Archie Comics. It then spun off into its own title. The first series of comics centered around the invasion of a bug-like race known as the Malignoids. Led by their queen, Maligna, they attacked the Earth from their Hive-World in an effort to destroy mankind and take over the planet. Raphael joined the Mighty Mutanimals for this adventure and helped bring about the end of Maligna. After the cancellation of their 2nd series, the entire team crossed back over into the regular "Teenage Mutant Ninja Turtles Adventures" title as a back-up series and occasionally as part of the main adventure. Their home was mainly a tropical island, which soon gained a neighbor, the turtle-like creature Slash. Slash was placed on a nearby island to placate him, for he loved palm trees. This gained the team the support of Slash, for all the man ever wanted to do was live among his beloved palm trees.

The Mutanimals (and Turtles) faced the super-villains Waster, Fist, Dead-Eye and Lynch on many occasions. In one dramatic event, the villains managed to kill the Mutanimals, Slash being too late to help them. This event made news because it was a surprising occurrence in Teenage Mutant Ninja Turtles Adventures, a TMNT comic primarily aimed at kids. The story was also surprising because it had involved time travel and, therefore, could easily have undone their deaths, but it did not. In fact, future versions of some of the Turtles said that the Mutanimals had died at the wrong time, that their deaths already involved an alteration of history. The crux of the 2nd series story was that the villainous Null was attempting to destroy both the present and the future Earth, and apparently had knowledge of future events, enabling him to do damage to the time stream. Null's ultimate fate (along with any chance of the Mutanimals' return) was never addressed due to the cancellation of the title.

Neutrinos

A race of 1950s-ish pointy eared people from Dimension X, appearing in the 1987 TV series and the Teenage Mutant Ninja Turtles Adventures. They travel in flying cars called "Starmobiles". Baby Neutrinos have psychokinetic powers. The three main Neutrinos seen in the show are Dask, Kala, and Zak. The Turtles meet the trio when they went through Krang's dimensional portal and became friends with the Turtles. Kala and Michaelangelo are often shown to be affectionate for each other, but it never clearly develops into a full romantic relationship. The TMNT have also met the Neutrinos' leader Zenter, his wife Grizzla and their baby daughter Tribble.

The known Neutrinos are:

Zak: Zak was the brother (possibly the oldest) of the three main Neutrinos and the possible leader.
Kala: Michaelangelo's love interest and the sister (possibly the youngest of the siblings) of the three main Neutrinos.
Dask: Dask was the brother (possible middle child) of the three main Neutrinos.
Zenter: The Neutrinos leader.
Grizzla: Zenter's wife.
Tribble: The daughter of Zenter and Grizzla. Has psychokinetic powers.

Ninja Tribunal

A group of four Ninjitsu masters who in the last episode of Season 4 of the 2003 TV series recruit the Ninja Turtles and four other humans as acolytes to combat an unspecified threat.

During the fifth, "lost" Season of the series, it is revealed that the Tribunal's self-imposed mission is to prevent the resurrection of Oroku Saki, a man/demon who once terrorized Japan as the second Shredder. To that purpose, they have recruited acolytes over the centuries, to whom they teach the hidden secrets of ninjitsu.

During the early fourth century, the people who would become the Ninja Tribunal, as well as a human Oroku Saki, were Japan's five greatest warriors, who rose to fame after they, under the order of the Emperor of Japan, slayed a feared tengu called The Shredder Tengu. They became known as "The Five Dragons".

Unbeknownst to all, their victory was not total. Oroku Saki, who had seemingly landed the killing blow to the Tengu, had secretly struck a deal with the demon. In exchange for power, Saki allowed the Tengu's spirit to depart its body and to enter the human's, allowing the Shredder to live on; the demon Saki had slain was but an empty husk. Now imbued with the Tengu's power, Saki began a reign of terror throughout Japan, aided by a demon army.

The four remaining Dragons, although powerful, realized that they would never defeat their former comrade in their current state. In order to increase their strength, they travelled through the globe in order to acquire the knowledge and power necessary to defeat Saki. Successful, they trascended humanity, becoming as gods themselves.

With their physical and mystical power increased, the four heroes engaged Oroku Saki in battle in order to bring an end to his tyranny. After finally defeating Saki (in the forms of dragons), the four warriors knew that the Shredder could not be destroyed - his evil magic was too great. So, they imprisoned Saki in a tomb, and hid his three artifacts, his helmet, gauntlet and body. If the three artifacts were to be united, the Shredder would rise again. They have since kept constant vigil over the artifacts, recruiting acolytes (the Ancient One among them) and imparting their secrets to them, secrets that eventually came to be known as Ninjitsu.

The members of the Ninja Tribunal are among the most powerful beings in the TMNT Universe. Their knowledge of the mystic arts allow them to perform tasks normally beyond the means of the series' other ninjitsu practitioners, such as manipulation of forces like the weather and energy; greatly enhanced speed and strength; and the manifestation of their astral selves into dragon avatars. Each member of the Tribunal is the master of the four distinct aspect of ninjitsu: Spirit, Weapons, Strength, and Stealth.

The Ninja Tribunal resides in the Lap of the Gods, a monastery mystically hidden in Japan. In addition to their powers, they command the Mokusai No Bushi, a group of mystical warriors made out of wood.

O'Neil Tech

In the Fast Forward cartoon series, O'Neil Tech is a high-technology company founded by April O'Neil and Casey Jones along with Donatello. It is the manufacturer of all Earth technologies. Security is pretty tight and the mainframe is protected by tons of firewalls and encryptions. By 2105, it was owned by their great-grandson, Cody Jones, but run by his uncle Darius Dun. Employees include the intern Starlee Hambrath. O'Neil Tech has a policy of no weapons creation. A few exceptions are a device that recreated the Turtles' weapons and a restricted storage room containing weapons and armor, which Darius claims is used for recycling.

Peacekeepers

In the Fast Forward cartoon series, the Peacekeepers are the law enforcement on Earth. Their job is to keep peace and order. Most of the time, they are lead by a robot known as Constable Biggles who the other officers. Their uniforms are blue and similar to British Police.

Punk Frogs

The Punk Frogs are a team of four mutated frogs appearing in the 1987 cartoon series, first appeared in "Invasion of the Punk Frogs". Wanting mutagen to create more mutants, Shredder asked Krang to send him a canister. But an ion storm in Dimension X caused the dimensional portal to send the mutagen canister to Florida. The mutagen has been spilled in a swamp and affected four ordinary frogs. There is a vacationing family nearby, a boy grabbed them and asked his parents if he could keep them, but his mother says no and order him to put them back. Right after he sent them back to the river, after recently been touched by the boy the frogs mutated into humanoid form, forcing the human family to flee (the boy wasn't afraid). The Shredder heads to Florida to recover the canister only to discover them. He realizes their potential and makes plans to returns to New York with them. He has given them clothes, weapons, and names them after his personal heroes of his own: Attila the Frog (after Attila the Hun), Genghis Frog (after Genghis Khan), Napoleon Bonafrog (after Napoleon Bonaparte), Rasputin the Mad Frog (after Rasputin the Mad Monk).

The Shredder tells them the Turtles are evil, but they eventually learn the truth and joins the Turtles. The Turtles lead them to a sewer line which will lead them back to their Florida swamp home.

Purple Dragons

The Purple Dragons (or Purple Dragon Gang) is a fictional street gang in several incarnations of the Teenage Mutant Ninja Turtles, appearing in the original comic books and the 2003 animated series. The Purple Dragon Gang is from the East Side in New York City, and are described as its "toughest".

The comic book Purple Dragons are notable only for being the first enemies the Ninja Turtles fight, in the first issue of the book.

The Purple Dragons' role is expanded considerably in the 2003 TMNT cartoon. Initially backed by the Foot, the Dragons dealt with the larger organization's street level crime.

During the gang wars that followed the Shredder's "demise" in the show's second season, the Purple Dragons, led by acting leader Dragonface and then Hun himself, split from the Foot and began a bid to take over the New York underworld. Unsuccessful, the Purple Dragon's were reabsorbed into the Foot.

A more definite split occurred during the show's fourth season; with Oroku Saki exiled in space and his daughter, Karai, ruling in his stead, Hun left the Foot and overhauled the Purple Dragons, turning it into a high-powered organization similar to the Shredder's. So far, the new direction has proved successful, to the point where the Purple Dragons are able to sponsor smaller gangs (such as The Turks) to the jobs they would previously do themselves.

Throughout entirety of the series, the Purple Dragons are led by Hun, one of the Shredder's second-in-commands and a long-time Dragon. During the times when he is unable to oversee its day-to-day operations (most notably during his time with The Foot), he leaves the job to a liutenant. Two of these are seen through the series, an unnamed one who is killed by the Shredder in the show's first episode, and Dragonface, who is seen leading the Dragons until the end of the City at War arc.

Rock Soldiers

File:Rockarmy.png

An army of Rock Soldiers.

The Rock Soldiers, sometimes called "Stone Warriors", are an army of stone-like aliens native to Dimension X, appearing in the 1987 TV series and the Teenage Mutant Ninja Turtles Adventures. They are led by General Traag, who is under the command of Krang. Physically, Rock Soldiers look like giant humanoids made of a smooth red-orange or in some cases gray rock, and they wear a helmet and boots. They carry Dimension X weapons, and their rock-like solidity makes them formidable in hand-to-hand combat.

In addition to the 1987 cartoon series and the TMNT Adventures comics, they were featured in three videogames, Teenage Mutant Ninja Turtles III: The Manhattan Project, Teenage Mutant Ninja Turtles: Turtles in Time and Teenage Mutant Ninja Turtles: The Hyperstone Heist.

Shadow Assassins attack an ailing Ultimate Daimyo

The Shadow Assassins are an organization that appeared during the Battle Nexus. They first came after Leonardo in the Hall of Champions, but were fended off. They later appeared when they tried to assassinate the Ultimate Daimyo. It turns out the assassins worked for the Ultimate Ninja who was trying to seek revenge against Leonardo for beating him in a duel. He also wanted to remove his father from power so he could gain control of his war staff and the Battle Nexus.

Sigmurethites

Sworn enemies of the Utroms, these aliens make their debut in issue 38 of Tales of the TMNT. A landing party of Sigs encounter a raging Leatherhead while on a mission to test the defenses of the Utrom stronghold, the TCRI building in New York.

Street Phantoms

The Street Phantons are a street gang that operate in the Turtle timeline of 2105. They have the ability to phase through solid matter. They can be attacked, but only if they are in physical contact with a human being. Their leader is a man named Jammerhead. The group operates out of a flying ship which has cloaking abilities.

TCRI

Casey Jones distracts the employees of TCRI while the Turtles infiltrate their building

TCRI (Techno-Cosmic Research Institute) is the front company the Utroms use to interact with humanity without revealing themselves. TCRI is responsible for accidentally losing the canister of mutagen that caused the mutation of the Turtles and Splinter.

TGRI

The equivalent of TCRI in the Teenage Mutant Ninja Turtles II: The Secret of the Ooze film. As the producers of the film wanted to shed all alien elements from the movie, TGRI (Techno-Global Research Institute) is a regular corporation. They are responsible for losing the canister of ooze that caused the mutation of the Turtles and Splinter. When the Foot Clan learned this fact, they abducted TGRI head scientist Professor Jordan Perry to force him to recreate the formula, and used it to create Tokka and Rahzar. Jordan Perry would then assist the Turtles in opposing the Foot Clan.

Triceraton

File:TMNT205EpisodeGuide.png

Triceratons battle the Federation for control of the Fugitoid

The Triceratons are an alien race who resemble anthropomorphic triceratops, and breathe a mix of nitrogen and sulfur. Outside of their native environments, they wear protective face helmets to provide them with necessary atmosphere. They destroyed their home planet for some unexplained reason.

The Triceraton Empire is a brutal society ruled by the despotic Prime Leader Zanramon. They wage war against the Federation, their sworn enemies. The Triceratons also have a serious combat thirst, like the Romans of Earth, and thus pit alien creatures against each other in coliseums. Despite its bloody appearance, the Triceraton Empire was once a grand republic and valued honor, until Zanramon took over. Soon, greed and corruption took over, turning the republic into a war-thirsty regime.

The Empire's reign was upset during an attempt to capture Professor Honeycutt, a robot scientist who had befriended the Ninja Turtles. Hoping to steal the Professor's teleporter device, the Triceratons became embroiled in fresh battle with the Federation. During this time, they captured the Turtles and sent them first to prison, then to the gladitorial matches.

It was in these barbaric surroundings that the turtles met Traximus, a noble warrior of the Triceraton Empire. He had been thrown into the games when Zanramon took over, and sought to break free. With help from the Turtles, who stole Zanramon's cruiser and then escaped back to Earth, Traximus and co. escaped. Traximus next appeared in the Battle Nexus, competing and looking for allies. He helped the Turtles in a fight against the evil Drako. Curiously, Traximus did not require a breathing mask in the Battle Nexus, for reasons which remain unknown.

The Triceratons trailed Honeycutt to Earth, where they invaded and did battle with the Turtles. They captured Donatello to extract the information. But Donatello didn't know were Honeycutt was. However, once it was determined that the professor had left Earth, the aliens departed. Unfortunately, Honeycutt just then returned, sparking another conflict between the arriving Federation and the returning Triceratons. However, Honeycutt managed to end the battle by infecting both sides with a virus. Zanramon ordered the Federation ships destroyed but any ship coming would be affected too. Mozar thought it was not honorable.

It was then that Traximus' rebellion attacked. Dethroning Zanramon with the support of Commander Mozar, Zanramon's second-in-command, Traximus destroyed the leader's chair to symbolize the end of the empire and revealed that a Triceraton senate will replace the dictatorship. He then helped the Federation, and Zanramon and General Blanque, the former leader of the Federation forces, were both imprisoned to help ensure the peace.

In the "Fast Forward" season, a few Triceratons were seen as workers on Earth.

The Triceratons also appear in the 1984 TMNT comic book.

Utrom

Wild West C.O.W.-Boys of Moo Mesa

In issue #21 of Mirage Studio's Tales of the TMNT title the Ninja Turtles meet Saturday morning television stars the Wild West C.O.W.-Boys of Moo Mesa. A villain from Moo Mesa, Sheriff Terrorbull, steals a magic crystal shard and escapes with it into the future. Hot on his trail is Marshal Moo Montana and his deputies the Dakota Dude and the Cowlorado Kid. With the help of the TMNT the crooked Sheriff's evil crime spree is brought to an end and things return to normal. Peter Laird was credited with helping plot this cross-over adventure as well as C.O.W.-Boys creator and Mirage Studio staff artist, Ryan Brown.

The C.O.W.-Boys return in issue thirty-two of Tales of the TMNT and fight Savanti Romero. Again the plot is by Peter Laird and Ryan Brown.

The C.O.W.-Boys of Moo Mesa make a guest appearance in episode #120 of the 2003 TMNT animated series. First airing on Saturday, August 12 of 2006, Teenage Mutant Ninja Turtles Fast Forward's third episode involved young Cody Jones's Robodojo being taken over by a living computer virus. Since the Robodojo was similar to the Danger Room in Marvel's X-Men, it generated holographic settings and characters to interact with. In this third episode, the virus created a wild west setting and, in the form of a virtual simulation, the TMNT visit the Tumbleweed Saloon on Moo Mesa. There they fight a cast of Cowtown villains and play a hand of cards with heroes Marshal Moo Montana, The Dakota Dude and the Cowlorado Kid. The featured Moo Mesa bad-guys are Sheriff Terrorbull, Boothill Buzzard, Shock Holiday, Big Bucks, Lone Grunger, Butch Cowsidy, Stub and Slick Willie Weasel, all who first appeared in the 1992-1994 " Wild West C.O.W.-Boys of Moo Mesa" animated ABC television series.

These were referenced in Channel Chasers, where a spoof of TMNT and C.O.W.-Boys is made as "Genetically Altered Adolescent Cows".

Y'Lyntian

A mysterious Y'Lyntian

The Y'Lyntian Empire was the most powerful civilization on Earth thousands of years ago. Their power came from a crystal named the Sun Crystal, which fell on their island during an ancient meteor shower with millions of small crystals. The power they learned to harness from the Sun Crystal allowed their society to quickly advance beyond all others, into a sort of half advanced half primitive civilization. Unfortunately, the Y'Lyntian's superiority eventually turned to arrogance, as they enslaved members of the less advanced human tribes and mutated them with the limitless power of their Sun Crystal into forms better suited to do their bidding: water-breathing fish mutants to control the seas, winged avian mutants to patrol the skies, and beast-of-burden mutants to toil for them. However, not all Y'Lyntians supported this abusive way of life, and a resistance movement formed. It never did manage to overthrow the powerful and corrupt Y'Lyntian government.

One day, the lower human tribes, sick of being abused by the Y'Lyntians, banded together and launched a common assault on the island. The Y'Lyntians had no trouble repelling the first wave using the power of the Sun Crystal, but the tides of the battle turned when their slaves seized the opportunity to rebel against their masters and destroy the Sun Crystal. Without the Crystal, the Y'Lyntian island collapsed and sank into the sea.

Some Y’Lyntians did escape their island on time, taking with them a chunk of the Sun Crystal, which they renamed the Crystal Moon. They hid from the other human tribes and built an Underground City. However, they soon found that the Crystal Moon didn't have the power to sustain them for long, and without their slaves they wouldn't endure. They thus decided to go into suspended animation until the next solar alignment would re-power their crystals, thousands of years in the future. Only the High Mage (a.k.a. the Entity) stayed awake to guard the City.

Over time, humanity forgot about the Y'Lyntians in all but legends, where they became the fabled Atlantis. The mutant slaves and their descendants hid from humanity and were forgotten as well. The Underground City remained hidden under what became known as New York City. Only the Turtles stumbled upon an old abandoned Y'Lyntian underground outpost, and eventually onto the City itself.

When the planetary alignment was near, the dormant Y'Lyntians awakened, and resolved to use their newly recharged power to raise their Underground City to the surface — an event that would greatly ravage the current Earth surface, killing billions, sinking continents — and once again dominate the other human civilizations. However, the Turtles, with help from a surviving member of the Y'Lyntian resistance, Brasalia, managed to destroy the Crystal Moon and with it the Underground City, putting an end to the Y'Lyntian threat.

It is possible however that the group of Y'Lyntians who escaped the island's destruction and built the Underground City were not the only survivors of the fall of their Empire. Other Y'Lyntian cities or outposts could still endure, hidden away elsewhere on Earth.

The Y'Lyntians were first encountered in the episode "Notes from the Underground". However, their full history only became known in "The Entity Below". The fish mutants were met in the episode "Sons of the Silent Age" and the avian mutants in "A Wing and a Prayer". The beast-of-burden mutants were never officially encountered, although their appearance is similar to that of the unnamed creature being hunted in "The Monster Hunter".
