Griffin Krank also know as the Toymaker is an Assassin and the former owner of Krank Toys and Models and the father of Cosmo Krank.
Griffin Krank infiltrated the assembly held by Lee Thompkins and Edward Nygma. He launched a toy plane with a bomb that would go towards Lee until it was deflected by Solomon Grundy.
Though the bomb exploded, Lee was unharmed as Jim Gordon and Alfred Pennyworth assisted with the evacuation while Griffin slipped away.
When Jim Gordon and Lucius Fox visit the toy store following the bomb-rigged attempt on Lee Thompkins' life, Cosmo was asked if anyone else worked here and states that his father was upstars as he goes to get him. After some near encounters with a large nutcracker with a gun and an explosive robot, Gordon and Fox run outside and see Griffin running as Cosmo stops them to keep them harming his father. Cosmo stated that he doesn't know why his father would try an attack on someone and that he had heard his father conversing with someone for a hit.
Though Cosmo didn't know who the person was. As Gordon and Fox leave the toy store, they tell the arriving police officers that Griffin's son is still inside. When it came to his sighting at Cherry's, Nygma followed him where it was revealed during this confrontation that Edward hired him. Nygma then figured out that his Riddler side acted on his own. Before anything else can happen, Gordon appeared and shot Griffin. While Nygma stated that Griffin didn't say who hired him, Gordon called up the Gotham City Police Department about Griffin being taken down.
- Griffin Krank is based on the Superman villain the Toyman.
