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. After his first defeat as Mr. Element, Albert Desmond stole the Philosopher's Stone from his cellmate. He develops a Psychic link to the stone and it always returns no matter what happens to it. When he temporarily retired from being Doctor Alchemy, his twin brother Alvin took it and quickly became the next Doctor Alchemy. Eventually Albert regained his title. The Philosopher's Stone that Morgaine le Fey uses in the Justice League episode A Knight of Shadows is not the same one Albert uses. Her stone is capable of anything, were Albert's can only change one element into another.
