2 years after season 6 and Bruce began Tim Drake's training, there is a new vigilante who has showed up in Gotham calling himself the Red Hood, and he is exterminating Gotham's criminal underworld, starting with the mob boss Black Mask. As Red Hood continues his killing spree, Batman begins to put the pieces together and discovers that the Red Hood is his adopted son and former Robin, Jason Todd who has evidently come back to life somehow. When Bruce finally confronts Jason, he has captured the Joker- the maniac who put him six feet under in the first place and tries to force Bruce into killing him, feeling betrayed that the man he considered a father didn't avenge his death and that Bruce has a new Robin. When Bruce stops Jason, he lets him go and Jason disappears.
