Donatello

Donatello is more socially awkward than his brothers. He does not have Mikey's outgoing nature or ability to make friends quickly, but his loyalty to the friends he does make is considerable. He also has a tendency to take things personally and deeply to heart, such as the care and protection for The Pulverizer and being the most upset by April's departure after the mutation of her father. Donnie can be very romantic and very loving especially with April.

Donnie is not without faults. He is anxious, tense under pressure, and can get easily frustrated especially when technology fails or performs ineffectively or when Leo and Raph rush him. Like Raph, he occasionally challenges Leo's leadership and can be aggressive when he gets provoked or into scuffles with his brothers.

Donnie is particularly skilled, having "a way with machines" and is the most intellectually inclined of the siblings. Of all of the turtles, he has devoted more of his time to non-combat oriented pursuits, such as the study of technology, biology, chemistry, mathematics, and metallurgy. This makes him very nerdy, especially in the eyes of Raph. Donnie is the voice of logic out of the turtle. In previous incarnations, Donnie is seen as second-in-command, but no such title has been established in this series, thus far.

Appearance: Donnie is a mutated turtle with brownish green skin and purple as his signature color. He wields a bō/naginata weapon. Donnie has distinct physical features like tall, skinny body, gap between teeth, and brown-red eyes. His mask tail length is unique among the brothers, and he wears various ninja gear including knee pads, elbow pads, bandages on ankles and wrists along with white finger wraps.
