Is the Joker an immortal serial killer stalking the dark chapters of Gotham's history?

He could be. Well, at least that's what the epic "Endgame" story arc posited. Yep, the Joker could have discovered a drug granting him immortality. This defined the villain as more a force of nature than a clown-themed malcontent.

Our black The Joker Endgame Men's T-Shirt is made from 100% cotton and sports the very cover to Batman #39. Rendered by artist Greg Capullo, The Joker sits on a throne fashioned by several victims of lethal laughter.

In "Batman: Endgame Part 5", Batman entreats the Court of Owls to help stop The Joker and his roving pack of Joker gas-infected denizens destroying the hell out of Gotham. The Court is okay with this, and politely declines. 

Batman has no choice: he summons his greatest enemies via upside-down Bat Signal and asks for their aid. They assist, begrudgingly.

Oh, and the Joker recently swam to the Batcave and relieved Alfred of an appendage. Uh-oh.
