Lazlo Valentin was a gifted surgeon who saw his gift as an artform. He turned to crime and became the criminal known as Professor Pyg.
Hell to Pay
Professor Pyg was going to give Two-Face surgery to even out the scarring in his face. However, Scandal Savage and Knockout interrupted the process, claiming he needed to help their "patient". Pyg reluctantly accepted their offer.
Upon finding Scandal and Knockout's apartment, Task Force X acquires the Get Out of Hell Free card, but they are intercepted by Vandal Savage and his men. Savage retrieves the card but leaves the wounded Knockout to die despite Scandal's pleas. As Savage escapes, Eobard Thawne places a tracer on his ship. Pyg is killed shortly after he attaches the "Get out of hell free" card to Savage's heart because he had outlived his usefulness.
