DR. MANHATTAN Dr. Manhattan is not your typical crime-fighting superhero, as he prefers to dabble in science at the atomic level, where his powers truly lie. But he will do his part in rooting out the Villains - every round, he will examine the atomic matter of one other player, which will reveal to him that player's own Superhero identity and role. In addition, Dr. Manhattan will then know exactly how to copy this role and use it for himself; he will be able to copy that player's role and use it himself for one round.
I assume that was his role.
