Donatello, he was the nerd. Also he had the longest reach in the games that I played. I also didn't like red or orange as much as blue and purple. Leonardo was bossy though.
My brother used to split up the action figures when we'd get them. I always got Donatello and Leonardo, and he always got Michaelangelo and Raphael (you know, since there was like 5 different versions of just those characters). Other than those 4, I got all the bad guys, and my brother got all the good guys.
