Hero Overview

Donatello Splinterson is the deuteragonist of the Teenage Mutant Ninja Turtles 2003 cartoon series. He is the younger brother of Leonardo, Raphael, the older brother of Michelangelo, and the third eldest/second youngest adoptive son of Splinter.

He was voiced by Sam Riegel, who also voiced Kudamon in Digimon Data Squad, Mephisto Pheles in Blue Exorcist, Shino Aburame in Naruto episodes 23-24, and Tristan Taylor in Yu-Gi-Oh! episodes 1-10.


Donatello has the same appearance as his brothers, except he wears a purple mask and favors a traditional bo staff as his weapon.


Donatello is analytical and introverted, and has a complex personality like in the Mirage comics. He typically has a very close, however platonic, relationship with April. He also displays closeness with Michelangelo akin to that seen in the original movie. Even more pacifistic than his other incarnations, Donatello shows a greater interest in technology than his ninjutsu training. Still, he always defends his brothers and frequently assists them through his technology, mostly vehicles and communication devices. He also tries the best to prepare for any situation like Leonardo.

Donatello is generally well-liked by all of his brothers, never engaging in major confrontations with them and is in fact the one who holds them in peace, best shown in the episode "Same As It Never Was". Leatherhead also considers him one of the most gentle-natured people he's ever met.



Like his brothers, Donatello was once an ordinary pet turtle bought by a young boy, until an accident caused the boy to drop them all into the sewer. The mutagen from the truck in the accident dropped into the sewer as well, covered them and the passing-by Splinter who adopted them afterwards. The mutagen mutated them all into being anthropomorphic. Splinter would ever since train them ninjutsu to protect them from the outside world.

Donatello and his brothers would then fight criminals and thwart their plans in the night. During this time, they also befriend April O'Neil and Casey Jones. However, their effort attracts the attention of Oroku Saki, the leader of the Foot Clan and the mastermind behind those crimes. He invites Leonardo to join him, but Splinter then tells the Turtles about Saki's true identity, the Shredder, thus Leonardo refuses and the Turtles become the Shredder's archenemies, especially after the reveal of his true identity as the Utrom criminal Ch'rell, who caused the Utrom spaceship to crash on Earth a millennium ago, thus set up a chain of events that led to the turtles and Splinter's mutation. Throughout the series, Donatello would assist the team via his technology.

Through much of the fourth season, Donatello and his brothers, save for Leonardo, are fully healed and recovered from their battle with the Shredder. When Leonardo is away to train with the Ancient One, Donatello, Michelangelo, Raphael and Splinter are seemingly killed by Karai, now the new Shredder. Thankfully, they survive and find a new lair. Leonardo then returns and battle Karai, before telling her that he gives her one last chance to leave his family alone.

In the fifth season, Donatello and his brothers become the Ninja Tribunal's acolytes, and he is the first one to focus his energy through his Amulet of the Acolytes. He and his brothers train themselves to fight against the Tengu Shredder, of whom the Utrom Shredder stole identity from. In the Fast Forward season, he and his brothers alongside Splinter are accidentally transported to a hundred years in the future, befriending Cody Jones, Casey and April's descendant, and Serling, while battling evil forces like Cody's uncle Darius Dun, Sk'Okanabo and Viral. They return to the present in the Back to the Sewer season and fight against a cybernetic copy of the Utrom Shredder, dubbed the Cyber Shredder. They then attend Casey and April's wedding. The Turtles also return in Turtles Forever, teaming up with their 1987 and later also Mirage counterparts to take down the Utrom Shredder, who was revived by the 1987 Shredder and Krang, once and for all.
