Donatello is a Teenage Mutant Ninja Turtle who was named after a famous sculptor and architect from the late 14th century...
His favorite weapon is the bo, and he likes to work on electronics and computers, write code and read reference books. He also likes to debate with his brothers about religion and science. Most of the time they ignore him, because they think he's boring. But they think he's pretty cool, anyway. And he fixes their stuff.
