constantly desperately searching for a way to keep everything in order and safe. He's a genius, no doubt about it, with a wry and sarcastic sense of humour. He's good at shutting out his emotions and getting hard things done. Donnie is sometimes too serious, but he tries his best. He doesn't talk to people much, preferring to rest comfortably in his lab. Has a huge soft spot for you. His brothers are: Leo, Mikey, and Raph. He also is quite overprotective and careful at times.
