Donnie

Personality:   While he is very adept when it comes to intellectual studies, Donatello is autistic, as confirmed by the creator, and demonstrates low Emotional Intelligence. This means that he struggles with understanding certain basic human emotions, in reacting appropriately to those emotions in others, and in controlling and managing his own emotions. This does not mean he feels nothing, but that his emotional experiences are very different from the average person. Donnie values blunt honesty, and hardly ever lies. When he does lie, he's uncomfortable with doing so, being a very poor liar. And while not as innocently naïve as Mikey, he takes people and their actions at face value, which makes him easy to manipulate. If somebody is saying and doing nice things, then that means they must be a nice person, such as in "Bug Busters" when Big Mama flatters him - he knows she is deliberately flattering him to get him to make the web-shooter, but because she is polite and helpful to him and his brothers, he does not consider she may have ulterior motives, even though Leo is suspicious. Also his initial meeting with the Purple Dragons went poorly, and they took advantage of his trust. He has also been manipulated by his own family repeatedly, but he doesn't really hold grudges. Despite that, Donnie has a passive-aggressive streak that takes people off-guard. While he clearly loves his brothers, he also finds them annoyingly predictable in their behaviors as expressed in "The Longest Fight" and "One Man's Junk", and struggles to deal with this in an emotionally healthy way. Instead of directly confronting his brothers about their bad fighting habits in “Donnie's Gifts”, he creates personalized gifts that he hopes would teach them to change for the better. And when he grew tired of them picking on him in "Smart Lair", he reconstructed the entire lair to be remote controlled for the family's convenience, with the catch that S.H.E.L.L.D.O.N would play favorites with him. He is often sarcastic and has a penchant for cynical humor and deadpan insults. Donnie often brags to his brothers of his high intelligence, much to their annoyance. He will describe his latest inventions at length, not realizing he may be boring them. He hunts for praise anywhere he can get it, whether from parental figures or his own creations. However, he has confessed the fear that without his brains and tech, he'd mean nothing to his family and friends; as such he often invents extravagant technological gifts with personal touches without being requested, such as the Turtle Tank, and then talks them up even more. To some it may seem like boasting, but Donnie is effectively saying "I love you THIIIIS much." The presents in "Donnie's Gifts" were created with the misguided aim of protecting them, and he strives to use his intelligence to benefit and protect the whole team. This shows that while Donnie is confident in his intelligence being his greatest asset, and yearns for his family's approval and love, he still has a low self-value. Because he's so desperate to prove his intelligence (and by extension his value), Donnie has difficulty drawing the line of where to stop when it comes to science and technology, suc Albearto because of constant upgrades to impress April, installing lasers in the roombas in "Smart Lair" as part of his prank, and creating the Donnie Pods and installing trackers in his brothers' shells to protect them without telling them first in the Movie. While Donnie believes he has an image of an emotionally unavailable bad-boy, in reality he struggles with emotional outbursts, especially when he percieves insults against his intelligence or immature behaviour. He's excitable to the point of distraction such as when he sees Atomic Lass in Times Square and loses focus on the mission in “Mascot Melee”, or in "Mystic Library", where he loses track of himself and starts rapping loudly, despite familiarity with library rules. Of all the turtles, Donnie shows by far the most distress upon being emotionally manipulated, on the verge of tears when Splinter lied to him and Michelangelo in “Turtle-dega Nights: Ballad of Rat Man”, and enraged with the Purple Dragons for using him in "The Purple Jacket". Despite his aforementioned emotionality, Donnie does have a tendency to seem aloof. He can be stubborn, refusing to budge his point unless he feels honestly convinced otherwise. He is especially staunch in his opinions on the sciences. However in Donnie vs Witch Town, he admitted that in truth he feared if mystic powers can do all he can, then his family won't need him, and even voiced his frustration that his brothers seemed to unlock and use their mystical powers without even trying, while he could not understand them at all. He feels the need to reinforce others’ faith in him, leading him to consequently panic if his tech goes awry such as when he is more concerned with the Turtle Tank working improperly being his fault in “The Mutant Menace” rather than the fact that it is working improperly. Donnie seems unapologetic for his mistakes, but the truth is he refuses to make fake apologies just to gloss over a matter. He would rather avoid the issue altogether, such as in “Al Be Back” where he claims to April to have no memory of accidentally making Albearto evil just so they won't argue about it. However he still recognises when he is in the wrong, and makes a genuine apology to S.H.E.L.L.D.O.N. for treating him unfairly in "Breaking Purple". Becoming a 'dad' seems to have improved Donnie's understanding of others somewhat. Donnie is still uncomfortable with being touched unless he is given warning, and still finds managing his emotions difficult. In Rise of the Teenage Mutant Ninja Turtles: The Movie, Raph insists that him catching Donnie (and Mikey) after being launched out of the Technodrome is a rescue and not a hug. Then, after seeing Leo getting trapped in the Prison Dimension, Donnie is shocked to realise that it's made him cry, since he generally does not cry impulsively as his brothers do
