Teenage Mutant Ninja Heroes/Hamato-Sawyer Clan

 * Leonardo "Leo" Hamato (voiced by Darren Criss): The Leader of the Ninja Heroes, and second-in-command of the Hamato-Sawyer Clan, born as a red-eared slider turtle. He is 15 years old. He and his turtle brothers are quadruplets (him being the oldest), but he is younger than Basque and Frida, making him the third oldest member of the group. His theme color is blue. Leo is the most mature, disciplined and skilled. Calm, cool, and collected, he always attempts to help his siblings to be the best ninjas they can. Because of his leadership, he's often challenged with the constant rebellion of Jack. However, Leo seems to be less experienced and more self-doubting and still perfecting his fighting skills and leadership abilities to make more solid decisions and gain more trust from his three brothers and four adoptive siblings. In the aftermath of Splinter's passing, he reluctantly stepped up to the increasingly difficult role as sensei, which adds even more pressure onto him. Despite his mature personality, he is courageous, enthusiastic, and is interested in a few anime and cartoons himself (like Space Heroes). An expert swordsman, he wears an ocean blue mask, blue knee and elbow pads, blue wristbands, a dark blue belt and strap over his right shoulder with a Turtle emblem on the strap, and pale blue rolled bandages wrapped around his ankles and fingers, and wields two special ninjato swords called Niten Ryu with the abilities to open portals and to teleport himself and/or others. As the leader, he also has an element of control over ice/snow, freezing opponents or creating icy weaponry. Like in the 2012 series, in addition to his natural ninjitsu skills, he eventually developed the strong innate ability to heal via an enchanted mantra known as "the healing hands." By chanting the incantation and making the right hand seals, Leo is fully capable of revitalizing his inner strength and counteracting even the most lethal of poisons and venom of "the healing hands." According to Splinter, he shows great gifts as a healer, and that being at the edge of his life had given him "a power that few martial artists can tap." His spirit animal is The Hawk, symbolizing keen observation, strategy, and the ability to maintain a clear perspective even in challenging situations. He has a huge crush on April, who later becomes his love interest/girlfriend. He is based on his counterparts from the 2003 and 2012 series, but with the mixed appearance from the 2012 series and Rise of the TMNT (the only difference in this series is that he doesn't have a rivalry with Raph, and instead has one with Jack).
 * Donatello "Donnie" Hamato (voiced by Bumper Robinson): The Brains of the Ninja Heroes, born as a spiny softshell turtle. He is 15 years old. He is the second oldest of the Turtle quadruplets, but is the fourth oldest of the group. His theme color is purple. Donnie is the most smartest, nerdiest, resourceful and inventive of the heroes. An intellectual, he often attempts to find an alternative way of reaching his goals. Donatello is a gifted polymath, possessing a natural aptitude for science and technology, and often speaks in technobabble. He is the most logical and rational of his siblings, possessing a high sense of ingenuity and serving as the second-in-command of the team. He is responsible for all technological innovations the team utilizes, such as technical expertise, intel gathering, vehicles, homemade bioweapons, and everything in between. Any science and math skill you can think of, he will do it all. Despite Donnie being quiet, sensitive, friendly, and a genius, he also can be sarcastic and mischievous at times and is more prone to panicking and losing his temper. Donnie is active and purpose-driven, but at times does not understand and/or has a hard time grasping the lectures of Master Splinter. A running gag is Raph scolding or hitting him whenever he explains something in scientific terms. Donnie also shows to have a heart as big as his intelligence as he, like his brother Michelangelo, care for humans and creatures that others find a nuisance like The Pulverizer and Bigfoot. His passion to help others is most demonstrated when he creates a retro-mutagen to undo mutations that happen throughout the series. He has a sidekick drone named S.H.E.L.L.D.O.N. along with many battle shells that he makes to help him in battle because of his species. Studying the art of Bojutsu, he wears a royal purple mask, silver convertible goggles with blue lens, purple knee and elbow pads, a purple belt with black pouches and a Turtle emblem, and pale purple rolled bandages wrapped around his ankles, wrists and fingers, and wields a powerful mystic metallic Bō staff with magic energy versions of his gadgets. The mystic staff could also link up with his technological attachments, and can convert into a naginata or shinai. His technological expertise is also enhanced with the ability to generate and control electrical currents, as well as the power of electricity/energy. His spirit animal is The Owl, representing wisdom, intelligence, and the ability to see things that others might overlook. It aligns with his role as the team's tech expert. He is based on his counterparts from the 1980s and 2012 series, but with the mixed appearance from the 2012 series and Rise of the TMNT.
 * Raphael "Raph" Hamato (voiced by Robbie Daymond): The Brawn of the Ninja Heroes, born as an alligator snapping turtle (but is skinnier like the other turtles in this version). He is 15 years old. He is the second youngest of the Turtles, but is the fourth youngest of the group. His theme color is red. Raph is the most temperamental and physically strongest of the team. Rebellious, cynical and quick-witted, he is often driven by his strong emotions. His quick temper tends to get the better of him, but he openly loves his siblings, parents, and allies. Unlike other incarnations, just like in the 1980s series, he listens to Leo's orders and respects and gets along with his three oldest siblings. Although his violent temper is toned down, Raph still can get cranky when annoyed or angry. Raph is a sardonic wise-guy, and supplies comic relief alongside Mikey, whose humor is usually attributed to his carefree and fun-loving behavior, whereas Raph is more sardonic and sarcastic. He is the comedian of the team who often comes out with sarcastic and witty remarks. He provides some of the comic relief for the show, constantly breaking the fourth wall. Raphael has a soft spot for his pets which help him calm him down. A normal pet turtle named Spike, which later mutates and becomes this show's version of Slash. Later on he got an alien turtle named Chompy Picasso. Raphael is also petrified of cockroaches until he managed to defeat the mutant cockroach, Spyroach. He wears a crimson red mask, red knee and elbow pads, a dark red belt with a Turtle emblem, and pale red rolled bandages around his wrists, hands and ankles, and uses a special pair of sai daggers with the abilities to amplify his own physical strength with red mystical energy constructs or to make clones of himself made from the same energy. His alligator snapping turtle nature also gives him the power to manipulate the element of metal and control metal objects, like turning everyday items into weapons. Other than his ninjitsu abilities, he also has the ability to grow big and strong like his 2018 counterpart, but only when in battle or when fueled by his temper. His spirit animal is The Panther, which suits his fierce and independent nature. It symbolizes strength, agility, and determination. He is based on his counterparts from the 1980s and 2012 series, but with the mixed appearances of the 2012 series and Rise of the TMNT.
 * Michelangelo "Mikey" Hamato (voiced by Greg Cipes): The Wildcard of the Ninja Heroes, born as an ornate box turtle. He is 15 years old. He is the youngest of the Turtles, but is the third youngest of the group (being older than Jack and Kusama). His theme color is orange. Mikey is the least disciplined and most fun-loving turtle. He is usually portrayed as the most agile and naturally gifted, contrasting his free spirit and inability to take training seriously. He often uses southern Californian surfer dialect and expresses his love of Pizza whenever brought up. Michelangelo is the most naturally gifted of the team but prefers to have a good time rather than train. The most energetic of the team, he is shown to be rather immature; he is known for his wisecracks, quick-wit, optimism, and love of skateboarding, pizza, video games, comic books, giant monster movies, smoothies and pranks. He has an active imagination and he names all the mutated characters. Michelangelo also has an affinity for animals, as well as a fear of squirrels. Whilst he is more interested in comics and cartoon shows (such as Crognard the Barbarian, which is a parody of Thundarr the Barbarian; and Super Robo Mecha Force Five, which is a parody of both Voltron and Super Robot Monkey Team Hyperforce Go!, the latter of which is also created by the series creator Ciro Nieli) than animals, he has a cat named Klunk. He still uses both catchphrases "Cowabunga!" and "Booyakasha!". His friendship/bromance with Basque is very similar to the one of Cyborg and Beast Boy from Teen Titans/Teen Titans Go. He wears a mandarin orange mask, a pair of orange headphones with a yellow M on each side, golden yellow-orange wristbands, orange knee and elbow pads, a dark orange belt with a Turtle emblem, and yellow-orange rolled bandages wrapped around his ankles and fingers, and fights using a special set of nunchaku with the ability to extend to great length and control will. His nunchaku can also convert into a three-section staff or bladed yo-yos. Mikey's wild and carefree personality is linked to the power of plants and nature, allowing him to manipulate plant life or create vines and thorns. His spirit animal is The Dolphin, which fits his cheerful and playful personality. Dolphins represent joy, community, and a love for life. He is based on his counterparts from the 2003 and 2012 series, but with the mixed appearance from the 2012 series and Rise of the TMNT.
 * Frida Franklin/Tigerlina (voiced by America Young): The Adventurer of the Ninja Heroes, earning the ability to transform into a half tiger half mud turtle hybrid called Tigerlina. He is 15 years old (almost 16). She is the adoptive older sister of the Turtles, as well as being the second oldest of the group. Her theme color is gold and bronze. Before Akari adopted her into the clan, Frida was a hacker that steals copies of video games for herself to earn some extra money since she and her then-decreased mother abandoned her toxic, abusive father. Confident, even-tempered, level-headed, passionate, imaginative, tender, fair-minded, calm, caring and somewhat humorous of the team, she is a serious do-gooder who does not joke around. A Hispanic tomboy with gold hair and bronze pupils, she is an experienced Ninjutsu fighter. Her enthusiasm and bravado puts her front and center for most of their bizarre adventures. She helps Leo lead the team, and informally likes to name the team "Mad Dogs". She has a habit of speaking in the third person in battle. Frida has numerous catchphrases: "Jumpin' Jackflash" when surprised, "Hot Soup" as a battle cry and "Power Punch-Jitsu" when using her tonfas. During battles, she wears a golden-bronze mask, gold knee and elbow pads, a dark brown belt with a Turtle emblem, and pale gold rolled bandages around her wrists, hands and ankles, and wields a special mystic pair of tonfas, which converts into Tessens, punch daggers or kunai knives. She also harnesses the element of fire/flames/heat/lava, with her tonfas and tiger-like abilities being fire-based. Being a spirited character, her spirit animal is The Tiger, symbolizing courage, strength, and fearlessness in the face of challenges. She is based on Frida from Teenage Mecha Ninja Turtles, as well as Venus de Milo, Robin from Teen Titans/Teen Titans Go, Jennika from the IDW comics, Leo's counterpart from the 1980s series, and Raph's counterpart from Rise of the TMNT.
 * Jackson "Jack" Reilly/Reptorai (voiced by Eric Artell): The Lone Ranger of the Ninja Heroes, earning the ability to transform into a half serpent half western pond turtle hybrid called Reptorai. He is 14 years old (almost 15). He is the adoptive younger brother of the Turtles, as well as being the second youngest of the group. His theme color is silver and gray. Before he was adopted by Akari and recruited into the team, Jack was a strict student of the Hamato-Sawyer Clan who wanted to become a powerful ninja, and he is close friends with Cody O'Neil. Serious, less emotional, temperamental, sarcastic, overlying eager and a loner of the team, Jack is usually seen as a lone ranger. A Caucasian lone teenager with blonde hair and silver pupils, he is a determined pupil with Ninjutsu. Like Raph, Jack is known for his temperamental and cynical personality, being short-tempered, aggressive, sullen, maddened, sarcastic, and rebellious. Instead of Raph having a rivalry with Leo, it's Jack being Leo's rival. He also boasts a somewhat less serious, more laidback, lazy, arrogant, immature, charming, sardonic, and joke-cracking personality. Despite his apparent immaturity and goofiness, Jack is quick-witted and strategic by nature. Despite coming off as somewhat arrogant, he also demonstrates insecurity and self-doubt like Leo. He is known as the trickster of the group (other than being a lone wolf) and thinks that his one-liners will "fire up the team", but is shown to have actual encouraging charisma. He is usually known as the self-professed "coolest" brother who possesses irreverent charm and a rebel heart. He also appears to have a crush on Hamato Miwa/Karai. During battles, he wears a silver mask, gray knee and elbow pads, silver wristbands, a dark gray belt and strap over his right shoulder with a Turtle emblem on the strap, and pale silver rolled bandages wrapped around his ankles and fingers, and wields a special mystic odachi sword, which converts into a lightsaber, a crossbow or any type of sword. Also, his serpent-like abilities involve manipulating the power of earth, such as creating rock barriers or causing minor earthquakes. As the lone ranger of the group, his spirit animal is The Serpent, representing adaptability, strategic thinking, and the ability to navigate complex situations. He is based on Jackson from Teenage Mecha Ninja Turtles, as well as Raven from Teen Titans/Teen Titans Go, Larota, Raph's counterpart from the 2003 series, and Leo's counterpart from Rise of the TMNT.
 * Basque Stone/Scaly-Sage (voiced by Khary Payton): The Heart of the Ninja Heroes, earning the ability to transform into a half dragon half sea turtle hybrid called Scaly-Sage. He is 16 years old. He is the adoptive older brother of the Turtles, as well as being the oldest of the group. His theme color is teal and green. Basque was a student of Midtown High and a child prodigy who loves technology, math, magic tricks, reading, economics and studying animal DNA before he was adopted into the clan by Akari. Lovable, shy, somewhat timid, friendly, cautious and clever, he is strong and smart, but suffering a lack of tough situations in battle. Basque is not as rowdy and violent as his siblings, but he can get a little annoyed with them on occasion. However, as a natural introvert, he is far quieter and more reserved than his siblings, rarely losing his temper. He is calm, sensible, quiet, friendly, passive, pacifistic and gentle. He does not get into a lot of confrontations with his siblings. He doesn't share the love of combat as his siblings do, instead opting for alternative methods of problem-solving and interests that stimulate the inquiring mind like Donnie. He is more interested in his work than in his ninjutsu, but he still attends ninja practice and works hard there as well as his projects. Despite his shy and kind-hearted personality, he can sometimes be more confident, level-headed, avoids physical contact, and sarcastic. Later, he learns to relax under stressful missions with Kusama's help and tries his best to help the team. He also begins to come out of his introvert charm and show off his true colors: reckless, sometimes violent, dramatic, extravagant, passionate, longs for genuine praise, gets irritated at times, argumentative, sometimes irresponsible, tends to be passive-aggressive, somewhat emotionless and aloof, and very protective of all his adoptive siblings which makes him the heart of the team. Basque has a teal Mohawk, green visor and teal green suit. His friendship/bromance with Mikey is very similar to the one of Cyborg and Beast Boy from Teen Titans/Teen Titans Go. During battles, he wears a teal green mask, a dark green visor, green knee and elbow pads, a forest green belt with teal pouches and a Turtle emblem, and pale green rolled bandages wrapped around his ankles, wrists and fingers, and wields a special high-tech bo/mystical magic hybrid staff that can transform into a multitude of weapons like drills, laser guns or a rocket-powered hammer. Being a dragon hybrid, he also controls water, using it defensively or offensively, like creating water blades or tidal waves. Other than his Ninjitsu abilities, with the help of Akari and Venus, he also learns some Shinobi and shamanistic magic abilities of his own. His spirit animal is The Dragon, representing wisdom, power, and a strong connection to ancient knowledge and mysticism. He is based on the character Basque from Teenage Mecha Ninja Turtles, as well as Cyborg from Teen Titans/Teen Titans Go, Talena, and Donnie's counterparts from the 2003 series and Rise of the TMNT.
 * Kusama Lane/Blazefeather (voiced by Tania Gunadi): The Ray of Sunshine of the Ninja Heroes, earning the ability to transform into a half phoenix half spotted turtle hybrid called Blazefeather. She is 14 years old. She is the adoptive younger sister of the Turtles, as well as the youngest of the group. Her theme color is pink and magenta. She is the childhood friend of Frida and a famous gamer known as Ninja Gamer before she was adopted by Akari and recruited into the team. Enthusiastic, youngest, shortest, happy-go-lucky, cute, funny, somewhat bipolar, somewhat shy and innocent, athletic, flexible, girly and mischievous, she is a positive ball of energy and enjoys being a ninja. A Japanese girl with black hair and a smiley attitude, she is a quick learner of Ninjutsu. Despite being a girly girl, she is not much of a party animal like Mikey as she would rather practice her combat skills and sometimes read a good book. She knows when to joke around, and when to be serious. She is the cutest of all, but don't let the pretty face fool you. When it comes to the bad guys, Kusama doesn't cut any slack for them, especially Shredder. She is also known to be an artist and awesome skateboarder with a wild colorful, and imaginative personality. Kusama likes to refer to herself as the artist of the group. She possesses a more childlike naiveness. She also has a strong passion for cooking and baking too, and she surprisingly makes the best food for the team. She also likes dancing, music and gymnastics, and loves to cheer people up. Kusama often acts as the peacemaker and the glue that keeps the team together, and it is really important to her that her family/extended family be on good terms with one another. During battles, she wears a pink mask, a magenta snapback cap with a heart in front, hot pink wrist gloves, pink knee and elbow pads, a dark pink belt with a Turtle emblem, and magenta rolled bandages wrapped around her ankles and fingers, and wields a special kusari-fundo that can create pink energy whips or tornadoes, and can be used as a grappling hook. The kusari-fundo can also convert into a kusarigawa, a whip, a hook, or a meteor hammer. Her phoenix-like nature also grants her control over the air/wind, allowing her to create gusts of wind, fly, and manipulate air currents. She is based on the character Kusama from Teenage Mecha Ninja Turtles, as well as Artemisia from Secrets of the Ooze, Starfire from Teen Titans/Teen Titans Go, Amoly, and Mikey's counterparts from the 1980s series and Rise of the TMNT.
 * Hamato Yoshi/Master Splinter (voiced by Ken Jeong): One of the leaders of the Hamato-Sawyer Clan who is a Japanese man mutated into an anthropomorphic rat. Generally depicted as wise and powerful, he raised the four turtles and four human orphans and trained them in the art of Ninjutsu. He is very cautious and protective of them, constantly warning them of the dangers on the surface. Yoshi is the son and heir of Hamato Yūta, the leader of the Hamato Clan whose rivalry with the Foot Clan came to an end when he was a child. During a confrontation with the Kraang, Hamato Yoshi was mutated into a mutant brown rat upon coming into contact with a rat prior to the conflict. Since then ever since alluding the Kraang, he trained the Ninja Heroes in ninjutsu. During the Triceraton invasion, he is killed by Shredder but this attempt is foiled when the heroes travel back in time to save Earth. In the second-to-last episode of Season 10, "Requiem of the Rat Sensei" he is again murdered by Super Shredder and buried at the O'Neil farmhouse. His spirit continues to watch over his family, imparting wisdom and advice to Leonardo, who reluctantly takes on the more challenging fatherlike role as sensei on his behalf. He is based on his 2003 and 2012 counterparts.
 * Master Akari Sawyer (voiced by Brenda Song): One of the leaders of the Hamato-Sawyer Clan who is a Chinese woman mutated into an anthropomorphic nine-tailed fox, and Splinter's childhood sweetheart and eventual wife after Tang Shen was killed by Shredder. Despite being good at Ninjitsu, she's also a powerful Shinobi magician. She is based on Tang Shen, as well as Chung I, Hamato Michelangelo from Teenage Mecha Ninja Turtles, and Splinter from Rise of the TMNT.
 * April O'Neil (voiced by Lea Michele): A 15-year-old Caucasian-American teenage girl who is a confident, courageous, benevolent, intelligent, and outgoing human companion of the Ninja Heroes. She was a former lab assistant to the mad scientist Baxter Stockman. She met the Ninja Heroes when they saved her from a squadron of MOUSERS chasing her down the sewers. She embarked on many of the team's adventures and aids them by doing the work in public while the Ninja Heroes cannot. Like in the 2012 series, she is able to possess extraordinary strong psionic/extrasensory abilities; having been born a human/Kraang mutant hybrid, as a byproduct of her late mother being experimented on by the Kraang before she was born, which she gradually learns to develop further and increase considerably in strength as the show progresses. Her psionic aura varies from being transparent, to white, to yellow. However later, her psychic and extrasensory powers have been greatly reduced, as she no longer can draw more strength from the mystical Sol Star necklace she herself had destroyed, but they are still far stronger than they were before she acquired the Aeons mystical gift. Her ninja weaponry is a Tessen like Frida, and later, a dragon tanto. She is Leo's love interest and later girlfriend in the series. She is based on her 2003 and 2012 counterparts. Unlike other incarnations, she's not the first ally.
 * Robyn O'Neil (voiced by Kat Graham): A 16-year-old African-American teenage news reporter for Channel 6 News who is the first human friend and ally of the Ninja Heroes. She is April's older cousin. She was the first one to befriend the Ninja Heroes, and has already known them for 5 years before the beginning of the show and the team looks to her as an older sister figure. Robyn is a smart, friendly, intuitive, fun-loving, virtuous and somewhat tomboyish, but sometimes unorganized and irresponsible girl with glasses who is constantly looking for a job to support herself which constantly goes wrong. However, despite her enthusiasm and bravado, she has a hard time making friends at school and is nervous about high school gatherings. When fighting, she also wields any blunt weaponry she can find, mostly a baseball bat. She is based on her counterpart from the 2003 series, as well the incarnations of April from the 1980s and 2003 series and Rise of the TMNT.
 * Casey Jones (voiced by Josh Peck): The teenage son of a former NHL player at April and Robyn's school who Robyn is hired to tutor for an extra credit assignment. He is also known as a hockey-masked vigilante, armed with an assortment of sporting goods that he carries in a golf bag. He is a close ally and friend of the Ninja Heroes. He has a crush on Buffy. He's prone to recklessness but means well. He is a close brotherly figure to Raph due to both sharing an eagerness to fight. He is based on his 2003 and 2012 counterparts.
 * Buffy Shellhammer/Angel Bridge (voiced by Amanda Leighton): April and Robyn's best friend and classmate from high school. Buffy is a rebellious but good-hearted and friendly teenage girl who came from a wealthy family and is the class president. She secretly moonlights as a mysterious street thug called Angel Bridge. She appears to have a crush on Casey. She is based on the characters Buffy Shellhammer from the 1980s series and Angel Bridge from the 2003 series and IDW comics.
 * Venus de Milo/Irma Sawyer (voiced by Kate Micucci): The teenage daughter of Akari Sawyer, and the honorary member of the Ninja Heroes. She also works as Robyn's Channel Six co-worker, and shares a special bond with Karai. Unlike the eight original Ninja Heroes she wasn't trained in Ninjutsu and rather utilised ancient shamanistic magic and manipulated orbs to fight. She wears an aquamarine mask in battle. She is based on Mei Pieh Chi/Venus de Milo from The Next Mutation, and Irma Langenstein from the 1980s series.
 * Cody O'Neil (voiced by Grant Gustin): April's 17-year-old older brother, Robyn's cousin and the heir of the O'Neil Tech. He has a crush on Starlee. He is the Ninja Heroes' other close friend and ally. He is based on Cody Jones from the 2003 series, and Keno from the Next Mutation series.
 * Starlee Hambrath (voiced by Amanda Brown): A bright and highly intelligent alien genius and O'Neil Tech intern from the planet Omatran and a friend of Cody and the Ninja Heroes. She is shown to have a crush on Cody. She is based on the same character from the 2003 series.
 * Hamato Miwa/Oroku Karai/Kiba (voiced by Kelly Hu): The only human child, until mutated, and willful daughter of Hamato Yoshi (Splinter) and the late Tang Shen, who was taken away from Splinter by Oroku Saki when she was just an infant and renamed Karai. She is the oldest child of Master Splinter. She is 16 years old. Initially, she was their sworn enemy, but soon became a trusted ally after learning the truth about her parents and grew even closer to Jack, who had a crush on her when they met. Karai later mutated into a violet-and-white viper called Kiba where an extra chemical ingredient enabled her to shift back and forth and assume hybrid forms. She had grown to ally herself with her adoptive siblings; the Ninja Heroes, her true parents; Splinter and Akari, April, Robyn, Cody, Starlee, Casey, Buffy, Venus and their allies. She is one-eighth Chinese through her maternal great-grandfather. She is based on her counterparts from the 2003 and 2012 series.
