Don

Donatello, nicknamed Don or Donnie, is a fictional superhero and one of the four main characters of the Teenage Mutant Ninja Turtles comics and all related media. He is co-creator Peter Laird's favorite Turtle. In the Mirage comics, all four of the Turtles wear red masks. In the animated cartoons, he dons a purple mask. The creators gave all four turtles different mask colors, in order to tell them apart.

He is usually depicted wearing a purple eye mask. His primary signature weapon is his effective bō staff. In all media, he is the smartest of the four turtles. He is commonly depicted as the tallest of his brothers, demonstrated in the Mirage and IDW comics, the DC crossover film, the 2014 reboot, and most notably, in the 2012 animated series. Donnie often speaks in technobabble with a natural aptitude for science and technology. His ninja skills are the lowest of the four turtles; as he relies on gadgets over combat skills. He is the third eldest brother of the turtles, and second-in-command. Like all of the brothers, he is named after a Renaissance artist; in this case, he is named after Italian sculptor Donatello.
