"Overwatch was my life's calling!" Reinhardt said, excited. "You see we have these robots called the Omnics. For some reason, a large number of them turned on humanity. It was the Omnic Crisis, and it was devastating. Overwatch was formed just to stop the war, but we evolved. Soldiers, scientists, adventurers, oddities, that's what they called us. We helped save the world, and then change it for the better."
