Joker

The Joker, in a purple suit, points at Harley Quinn in a dimly lit room, then the scene cuts to a close-up of the Joker laughing maniacally against a red background, followed by a shot of a television screen displaying a black-and-white image of the Joker with the GCN logo, then a blurry image on the television, then a close-up of a man with red hair laughing, and finally a close-up of a man with pale skin and dark makeup screaming with his mouth wide open.
