I have to give this one to Damian. He's not only the son of Batman, he's the grandson of Ra's Al Ghul, the immortal warrio, son of Talia, the most badass and meticulous woman ever, he trained since birth by the League of Shadows (the people responsible for Batman's training) [b]and[/b] he's genetically engineered to be a perfect mental and physical specimen! While he may be a huge c.unt in his younger years, he was able to beat Tim Drake to a pulp when he was 11 (I think so). Grayson is just all around a good character, but he's infinitely better as Nightwing. Todd is tragically awesome, and anyone who has seen "Batman: Under the Red Hood" (which I highly recommend watching) knows he can go toe-to-toe with Bruce. And Drake was/is one of the few people to deduct Batman's secret identity before being told. He is by far the smartest of the Robins (although, Damian may still have the advantage.) Note: there are many other robins, but I don't really care about them. These are the good ones.
