Rex Larson was a trader in illegal animals.
History[]
Larson set up a smuggling ring for rare and endangered animals, which his men stole. One of the animals was Zatanna's white tiger. Zatanna and Catwoman teamed up to get the tiger back. While Catwoman dealt with the henchmen, Larson took his shotgun and tried to shoot Zatanna and her magic. He was eventually taken down by Catwoman and imprisoned in the tiger's cage by Zatanna.
