Batman's history at DC Comics has been explored in great detail over the almost ninety years of the hero's existence in print. This has extended beyond the story of just Bruce Wayne and his friends, family and supporting cast have gotten their moments in the sun. One of the most important figures in Bruce's life was his father, Dr. Thomas Wayne. Best known currently for his role as Flashpoint Batman, Thomas wore the cape and cowl decades before the doomed timeline was introduced in 2011.
