When Oz was only 12, he witnessed the downfall of his family and they losing all of their fortune by the events set in motion by the Waynes and Hamilton Hill. This led to his father committing suicide, and his mother being deemed insane and sent to Arkham Asylum so the Waynes could take control of the Cobblepot's lands. Because his mother's apparent insanity, Oz was picked up and bullied by taller children at school, but he was always protected by Bruce.

Afterwards, Oz established himself as a criminal, building numerous illegal business, such as weapons dealing and underground fighting rings, whereas he was arrested more than once, serving seven years in prison.
