That name sounds like a paradox almost. Guessing that a recently new character in the comics. Guess DC Collectibles is going full blast with this line of reinterpreting new characters into the Timm style.A DCAU Batman Who Laughs figure was announced today
But seems like someone at a con should ask and record Conroy doing a take on Hamill's Joker laugh then splice it with a gif of this figure or something.
