Griffin Krank was a minor character in the television series Gotham, appearing in the Season 4 episode "Pieces of a Broken Mirror". He was the owner of a toy shop in the Narrows and was also a killer for hire, using weaponized toys of his own creation to carry out his murders.
While Dr. Lee Thompkins was holding an assembly for the residents of the Narrows, Griffin infiltrated the assembly and launched a toy plane with a bomb that would go towards Lee. The plane was deflected by Solomon Grundy and exploded without killing anyone. Jim Gordon and Alfred Pennyworth then assisted with the evacuation while Griffin slipped away.
When Gordon and Lucius Fox visited Krank Toys & Models following the bomb-rigged attempt on Lee's life, Griffin's son was asked if anyone else worked here and stated that his father was upstairs as he went to get him. After some near encounters with a large nutcracker with a machine gun and an explosive robot, Gordon and Fox ran outside to see Griffin running to his car as his son stopped them from pursuing his father. Cosmo stated that he didn't know why his father would try and attack someone, but he had heard his father conversing with someone for a hit, though he didn't know who the person was.
That night, Griffin was cornered by Edward Nygma in the alley outside of Cherry's. When Nygma demanded to know why Griffin was trying to kill Thompkins, Griffin was confused and told Nygma that he was the one who hired him. Nygma then figured out that his Riddler personality had acted on his own. Before anything else could 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.
