1. Tim Drake
He has always been my favorite Robin because his story compared to all the Robins is unique. He's so much more different. Maybe Stephanie is kind of alike, but she doesn't have his seriousness. The fact that even Bruce said that one day he could be a better Batman pretty much sums everything up.
2. Bart Allen
I don't know. He's just a really great character especially in Geoff John's Teen Titans run. His transfer from Impulse to Kid Flash was really an interesting story.
3. Damian Wayne
His bad assery is just off the charts.
4. Stephanie Brown
My favorite Batgirl N/A. I've loved her ever since I read Robin, and for her to not be in New 52 at all is just sad.

Under the Red Hood..nuff said.
