#5: Robin (Batman #428)
Jason Todd was the smart mouthed Robin who took over the mantle after Dick Grayson left to become Nightwing. In A Death in the Family, Todd met his grisly fate after the Joker beat him half to death with a crowbar and then detonated a bomb next to him. This marked Batman's first great defeat. Jason Todd's death is interesting because DC Comics let the fans vote on whether he lived or died. And, because fans never really embraced the new Robin, they voted to bump him off. That’s just cold. Oh well, not to fret. Jason Todd has already been brought back to life (the less said about that the better) and is now torturing Batman whenever he gets the chance.
