Joe Chill's son Joe Jr. briefly assumed the mantle of Reaper, as part of a plan to gain revenge by driving Batman insane.

Emulating the Reaper's mission of zero tolerance towards criminals, and using Caspian's costume and weapons, Chill, in collaboration with his sister Marcia, attempt to lure Batman into a confrontation, where they would finally dispose of the Dark Knight with a very different kind of weapon. Chill's schemes are hampered by the arrival of his own son, Joey, whom Chill attempts to bond more with like his father did with him. It is revealed that Chill witnessed his father's death at the original Reaper's hands, though he could not make out Bruce Wayne's unmasked face. Overcome with grief, Chill seeks to gain revenge on Batman, hence the reason he has taken the Reaper identity. Batman in the meantime faces some personal issues with Rachel Caspian, who has returned to Gotham convinced The Reaper is her father reborn. Chill and his sister use this to their advantage, plaguing Rachel with encounters as a way to cast doubt in her and Batman's minds that he is the returned Judson Caspian. (It is also revealed in this story that Joe Chill Sr.'s body was stolen before it could be taken into custody at the end of Year Two). Reaper also uses an explosive to destroy the cornerstone of the Wayne Foundation building, freeing his father's old gun, which was used to murder Batman's parents.

Batman is eventually captured by Chill, who unmasks the unconscious crimefighter, but does not recognize him, because Batman applied elaborate makeup and hair dye to alter his physiognomy. Chill subjects Batman to a video reel and a hallucinogenic drug that reduces Batman to a quivering wreck suffering from survivor's guilt. Chill has Batman posed at the top of a tall pedestal overlooking a pool of acid, and hopes Batman will kill himself. When Marcia, who saw her father as nothing more than a thug who abused her mother, and cared nothing for the revenge plot, attempts to double cross Chill in order to deliver Batman to mob boss Morgan Jones, Chill slashes Marcia, apparently killing her. Robin arrives on the scene and coaxes Batman out of his hallucinogenic haze, spurring him to break free of his bonds. Batman and the Reaper fight, and Batman emerges victorious. As Batman holds the unmasked Chill over the acid pool, urged by Robin to drop him in, Chill's son Joey reveals himself and his father's identity. Deciding to act on the indecisions that he faced when he had Joe Chill at his mercy years earlier, Bruce spares Chill's life. After the police arrive and Chill is taken away in an ambulance, Batman goes to a bridge and discards Joe Chill's firearm into the ocean.
