Nope, we want Donnie as our representative, he's way cooler.
...Okay, I want that, I haven't exactly held a vote on it. Donatello from the Ninja Turtles, Frank Martin from The Transporter and with some serious squinting Sergeant Todd from Soldier, those are my autistic role models in media.
...And I guess that power ranger from the newish movie can join too. I didn't enjoy it as much as a movie, but they put effort into the representation and it was kind of cool to see a guy be the "heart of the team" for ones. So fine, he's in.
I'm keeping my eyes open for members from other age and gender groups.
Leonardo might have some mild daddy/authority/stress/being too serious all the time issues, but I'm not sure we need to shoehorn him into anything foe that. Also depending on the incarnation of course.
