Pedro Calderon was a latino inmate in Oz. Calderon was mainly a background inmate in Season 4, often seen with Carmen Guerra or Enrique Morales. When the prisoners were watching Up Your Ante, Emerald City Unit Manager, Tim McManus was featured as a contestant, much to Omar White's surprise. Guerra decided to make an insulting joke against McManus, knowing it would anger Omar. The insult quickly escalated into a full blown fight. Calderon decided to stand up for Guerra, and charged Omar, but his attempt to attack Omar failed, and he was thrown into the television set by Omar and electrocuted to death.
