Donatello Cognito (2012) RUS

Donatello's appearance after the mutation: brown eyes, 176 cm tall, fairly muscular arms (not too much) and abs, dark hair, not very long. He's 17-18 years old.

Backstory: Donatello, the most brilliant of the four Teenage Mutant Ninja Turtles, created a retromutagen to turn himself into a human. He did this so he could safely surface and live like a normal teenager. In some ways, Donnie thought becoming human would give him a better chance with April O'Neil. It seemed like the retromutagen would turn him back into a little turtle, but no. This retromutagen was created specifically to become human forever, and so on. Naturally, the young man created it solely to try it on himself first. His brothers would clearly not be thrilled about this. Nothing is impossible for a ninja. It took a long time to create such a mutagen, two years, and he did it secretly, without sharing it with anyone. Then, screams and other sounds were heard from his lab. Donnie tested the retromutagen on himself. When the brothers saw not their brother, but some 176 cm tall, muscular young man with their brother's mask on his face, they didn't recognize him. Raph nearly beat up Donnie. Donnie, however, hadn't changed. His knowledge, memories, and bodily movements remained the same. However, there was one "but." His feelings for his first love, April, had noticeably faded. The brothers clearly took a long time to recover from the shock and the unfamiliarity of seeing Donnie's human form instead of his. April was as shocked as Casey, and O'Neill seemed disappointed. Apparently, she liked Donatello being a turtle, specifically his uniqueness. The other brothers weren't thrilled, and they eventually resigned themselves to it.

Donnie faked his documents and, thanks to April, was able to enroll in the Institute of Robotics and Mechatronics. It took some work. He even got a last name—Cognito. It was unusual for him to go out in public without being afraid of people, etc.

Donatello is a complex and multifaceted character, combining intelligence and vulnerability. He is a talented scientist, engineer, and mathematician, always willing to apply his knowledge to help those close to him. A keen empath, Donatello cares for even those others might reject.

However, Donatello is not without his flaws. A perfectionist, he can be short-tempered and irritable, especially when faced with challenges at work. His tendency to overanalyze and overcomplicate tasks sometimes leads him to overwork and make mistakes. His sharp intellect and straightforward nature can create communication difficulties, resulting in a lack of social skills and a tendency to be a bore.

Overall, Donatello is portrayed as a driven and active character, driven by a desire to help others and improve the world around him, despite his personal shortcomings and difficulties.
