Dr. Alchemy was one of the villains hanging out on a Central City bar. He was drinking a pint by the counter, laughing with the Thinker at something. When Batman, Orion and the Flash entered the bar, he made a run for it.
The depicted subject bears the likeness of Doctor Alchemy from the DC Comics; however, the DCAU character was never named on-screen, or otherwise. The title of this article is conjecture based on the character's likeness.
