During World War II, he leaves America to defend England, and fights Simon Culp again. An exploding bomb causes Culp's body to fuse inside Shade's body. Unaware of this, the Shade returns to Keystone City. This was the time of the Golden Age of Heroes, and of them all he chooses Jay Garrick, the first Flash, as his adversary. During this time, Culp is able to subtly affect the Shade's behavior, and was even able to take over Shade's body completely when the latter is tired.
