F!Donatello

Personality Donnie has an aptitude for recklessness, delighting in exciting and dangerous activities, such as when he tests out the Turtle Tank's rocket taxi, and enjoys the experience despite having no control of the vehicle and traveling hundreds of feet in the air in "Late Fee". He also has a violent streak as Donnie regularly attempts to physically attack others without hesitation and can be wild, typically acting more like a deranged scientist than a caring man of knowledge. Donnie loves the dramatic as much as he is dramatic himself, sometimes bursting into song, generally speaking in a bombastic manner about himself and events, and being prone to being extravagant with his plans, such as when he desires uranium for his inventions in "Down with the Sickness". Although Donnie perceives himself as being emotionless, he is actually quite passionate, becoming easily irritated, especially when others fail to listen and/or appreciate his intelligence, becoming excited at times to the point of distraction, such as when he sees Atomic Lass in Times Square and loses focus of the mission in "Mascot Melee", and being deeply saddened and hurt to discover that Splinter lied to him and Michelangelo in "Turtle-dega Nights: Ballad of Rat Man". He also craves genuine praise, particularly from adults. Despite his aforementioned emotionality, Donnie has a tendency to be aloof. Donnie can be argumentative, contradicting others' views with his own and persistently trying to convince others that he is right. He is especially firm in his opinions on the sciences, viewing them as superior to mystical powers, and as such refuses to use them throughout the series, unlike his fellow Mad Dogs. This stems from Donnie's arrogant nature.
