- We've been meaning to invite you over for tea...and a good, ol'-fashioned pummeling. Unfortunately, we're all out of tea.
- — Professor Pyg src
A self-styled Eco terrorist, Professor Pyg and his partner, Mr. Toad, showed up in Gotham with the intent to hunt down and eliminate the main investors in a land deal that had destroyed a wetlands animal preserve. The pair began their hunt by chasing down and tranquilizing Simon Stagg, head of Stagg Industries. Flushed with victory, the pair posted a video clip online for all to see, where Pyg taunted Stagg, and his other potential victims, with a modified version of the classic nursery rhyme "Little Jack Horner", itself based on a land deal gone bad.
