Time Passed By by FermiumIce. Dick Grayson, enter Barbra, exit Dick, enter Nightwing and Jason Todd as Robin, exit Jason Todd (death by Joker). Enter Tim Drake, Enter Jason Todd as The Red Hood, Enter Damian Wayne as Robin. Notice I didn't say "enter Alfred" for he has been there since the beginning. Finally Damian as The Batman
Three versions of Jason: before Robin, as Robin, after Robin. The last bit breaks my heart. Jason could have done so much, but Joker took his light future away from him and instead pushed him towards the darkness.
