A tie between Dick Grayson and Tim Drake. Honestly they proven to use all of Batman's teachings to the fullest extent. It's virtually バットマン 秒 generation. Not to mention their personalities are pretty awesome as well. I don't like the 秒 robin as much as the other two simply because he was way too hard-headed and (IMO) annoying.
I really 愛 them all to bits, but if I absolutely had to put them in an order, it would be: Dick Grayson Jason Todd Tim Drake Steph Brown Damian Wayne Which I find kinda funny since that's the order in which they came :3 (BTW I like to pretend that the whole Carrie Kelly thing never happened :/)
The Teen Titans version. I prefer this version of the character because any other versions in my opinion didn't have the same charm as the Teen Titans version of Robin.
