Professor Pyg

Professor Pyg is a supervillain who appears in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. Pyg was created by Grant Morrison, Andy Kubert, and Frank Quitely and debuted as a corpse in the alternate reality story Batman #666 (July 2007) before being introduced as a recurring character in the mainstream DC Universe two years later in Batman and Robin #1 (August 2009). Professor Pyg was re-introduced following DC's The New 52 comics relaunch in 2011, appearing throughout the continuity and the subsequent DC Rebirth relaunch that began in 2016. The character's in-universe real name is Lazlo Valentin, a scientist who suffered a schizophrenic breakdown that led him to become a supervillain who wears a pig mask.
