Main characters.
Teenage Mutant Ninja Turtles.
The Teenage Mutant Ninja Turtles are a team of anthropomorphic mutant red-eared slider turtles who were hidden ever since their mutations within the sewers of New York City and usually go up to the surface only in the night time.
Leonardo.
Leonardo (nickname Leo) is an enthusiastic ninjutsu student, wears a royal blue mask, and fights with two long swords called Niten Ryu. The oldest and most mature of the four, he is the fearless leader of the Ninja Turtles. 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. Since the episode "The Deadly Venom", he is the only Ninja Turtle who is capable of using the spiritual, healing abilities of "the healing hands" technique to heal himself and others which enshrouds his body in a white aura by chanting the mantra and the right hand seals.
Donatello.
Donatello (nickname Donnie or "Don") is the middle child and third brother of the family. He is in charge of the design and manufacture of all of the tools and weapons in the Turtles' arsenal. He is also a gifted hacker. He wears a purple mask and fights with a rokushakubo which converts to a naginata via a blade inside one end of the staff. He has a huge crush on April and a rivalry with Casey because of it.
Raphael.
Raphael (nickname Raph) is the second oldest of the turtles. He wears a red mask and fights with two sai. Known for his rage, he commonly takes it out on Mikey, and on occasions Leo, due to their feud. Raphael sports a chip at the top of his shell as a result of Splinter's earlier encounters with the Kraang that were after him.
Michelangelo.
Michelangelo (nickname Mikey) is the baby of the family and is a lover of video games, skateboarding, pranks and pizza. He wears an orange mask and fights with two nunchaku which convert into kusarigama via a blade inside of one of the sticks of each nunchaku and extra lengths of chain stored in the other. He loves to prank Donatello and Raphael the most. It is easy to tell that he is the youngest sibling on account of his most childish behaviors, being the least mature turtle out of the four. He has an active imagination and he names all the mutated villains.
Allies.
Splinter.
Hamato Yoshi (also known as Splinter) 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 Turtles in ninjutsu. During the Triceraton invasion, he is killed by Shredder but this attempt is foiled when the turtles travel back in time to save Earth. In the second-to-last episode of Season 4, "Requiem" 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 father-like role as sensei on his behalf.
April O'Neil.
The sixteen-year-old daughter of Dr. Kirby O'Neil and the love interest/crush of Donatello. Unlike her previous incarnations, she possesses 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; particularly in Season 4 and Season 5. Her psionic aura varies from being transparent, to white, to yellow. Since "Tale of Tiger Claw" 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 and, later, a dragon tanto.
Karai.
Hamato Miwa is the only child 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 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 Leonardo. Karai later mutated into a violet-and-white desert horned viper where an extra chemical ingredient enabled her to shift back and forth and assume hybrid forms. She had grown to ally herself with her brothers; the Turtles, her true father; Splinter, April, Casey & their allies. She is one-eighth Chinese through her maternal great-grandfather.

The Kraang are a race of brain-shaped aliens from Dimension X, piloting robotic bodies called Kraangdroids that are responsible for bringing some mutagen to Earth a thousand years ago. As revealed in "The War for Dimension X", the Kraang are actually Utroms that are now psychically controlled by Kraang Prime resulting in the Kraang Hive Mind.

The Aeons are an ancient alien race of benevolent, ethereal beings that hail from the planet Zalvadal, a world of vast, beautiful gardens and tranquility that contains all of the sacred knowledge in the cosmos. They were the very first extraterrestrials to evolve into higher beings of mighty power. The very source of all their strength is a mighty crystallized artifact called the Sol Star, containing the very essence of power and life itself. Once hidden away, the entire world turned pure evil and corrupted the Aeons as well. When April had restored the world to its former state and splendor by placing the mystical Sol Star on its rightful place, the grateful Aeons gladly gave her a small fragment of it, assuring her that it would grant her luck and great power. However, they may not have been aware of how the Sol Star fragment was gradually corrupting April to the point of insanity, in addition to further developing and magnifying most of her psionic abilities to tremendous levels.

The Triceraton Empire has been at war with the Kraang for millennia, a conflict that has resulted in the destruction of the Triceraton home world through the Heart of Darkness (a black hole generator) and thus left the Triceratons obsessed with annihilating their enemies by any means necessary, such as destroying any planet that the Kraang want to take over. They are also enemies with the Salamandrians. In the first half of the fourth season, having appeared to wiped out the Kraang in the season three final, the Triceratons replace the Foot Clan as one of the main villains in the series.
