The Penguin is enlisted to Joker's schemes through blackmail. Joker announces on the radio that he has learned the secret identities of Batman's allies, and within 72 hours they will all be killed by Batman. Joker ties up Batman in a trap and explains that he views himself as the "court jester" to Batman as "king." He believes his job is to deliver unpleasant truths to Batman that he wouldn't hear from anyone else. Joker has instead rigged it to explode where Batman would have, injuring Nightwing in the blast, and filled the reservoir with corpses of those who would have been poisoned by it anyway.

Batman and Nightwing try to stop Joker poisoning the reservoir. They determine that Joker is revisiting his most famous crimes and reinventing them with new twists. Batman visits Jim Gordon to protect him, but Gordon is hospitalized by poison in his old photos. Joker needs a servant for an upcoming celebration and has chosen Alfred for his connection to Batman Incorporated. Batman escapes the vat and returns home to learn that Alfred has been kidnapped. The Joker visits Wayne Manor now wearing a loosely reattached face, and attacks Alfred Pennyworth with a hammer. Harley warns Batman that Joker is not the same, and a prerecorded message by Joker announces that he will liberate Batman by killing Batman's family.

Harley Quinn is disguised as Red Hood, and traps Batman in a vat filling with chemicals. The poison has been altered to leave victims frowning, and a clue leads Batman to Ace Chemicals where he first encountered the Joker. Ironically, the Joker uses his venom to kill every single guard and leave Hady unharmed. Batman and Gordon set up a protective GCPD cordon around Hady. The Joker kills John Claridge on live television, and swears that he will murder Mayor Hady by midnight. Batman alerts the extended Batman Family that Joker has returned. He slaughters several cops and taunts Jim Gordon, then steals his own severed face out of the evidence room and leaves. The Joker returns to Gotham City after a year, appearing at GCPD Headquarters. Escaping the asylum without a face, Joker practically dropped off the face of the planet. The Joker had a scheduled meeting with the villain known as Dollmaker, who was given permission to cut off the Joker's face by the clown, himself. But, getting captured was part of his plan. The last time he was seen, the Joker was captured and sent to Arkham Asylum. The Joker has been absent from Gotham City for over a year.
