Fan Casting Donatello | Donnie in Teenage Mutant Ninja Turtles

Donatello is a mutant soft-shell Turtle, and the second oldest of the four ninja sons adopted and presumably trained by Hamato Yoshi (a.k.a. Splinter), along with his brothers Leonardo, Michelangelo and Raphael. He is the team's resident tech-head. Of the Turtles, he is the one with the fewest changes compared to previous incarnations. He wields a high-tech version of his traditional bō, which is also a "Transforming tech-bo".
