Donnie has an aptitude for recklessness, reveling in thrilling, dangerous activities, such as when he tests the Turtle Tank’s taxi rocket, and enjoys the experience despite having no control of the vehicle and traveling hundreds of feet into the air in “Late Fee”. He also has a violent streak as Donnie regularly attempts to physically attack others with little hesitance and can be wild, typically acting more like a deranged scientist than a heedful man of knowledge.
Donnie loves the dramatic as much as he himself is dramatic, at times erupting into song, generally talking in a grandiose manner about himself and events, and prone to being extravagant with his plans, like when he desires uranium for his inventions in “Down with the Sickness”.
While Donnie perceives himself as being emotionless, in reality, he is quite passionate such as being easily irritated, especially when others don’t listen and/or appreciate his intelligence, excitable sometimes the point of distraction, such as when he sees Atomic Lass in Times Square and loses focus on the mission in “Mascot Melee”, and is deeply saddened and hurt discovering that Splinter lied to him and Michelangelo in “Turtle-dega Nights: Ballad of Rat Man”. He also longs for genuine praise, particularly from adults. Despite his aforementioned emotionality, Donnie does have a tendency to be aloof. 5’5ft, 15 years old.
