The Batman 2004 Laughing Bat

Upon entering the Joker’s mind, Batman’s costume begins to warp. The black and grey are replaced by purples and neon greens. His cowl grows elongated, his gloves become spidery, and his cape frays into jagged tatters. Most horrifyingly, his stoic, clenched jaw is pried open into a rictus grin—sharp, white, and ear-to-ear.
