While one of the shooters was captured, two escaped prompting the Human Torch to chase after them. When the motor was delivered and Fear learned of the Torch's involvement, he tested his device on his two hired thugs, leading to a complete success. Hearing the Torch snooping around his hideout, Professor Fear sent his pliant slaves to capture the hero. Succeeding, he attempted to use the device on the hero when Toro came crashing into the room. The young hero used his flame powers to destroy Professor Fear's device and the Nazi scientist was easily defeated and turned over to the authorities.
His subsequent fate is unknown but he liked died or committed suicide like many other Nazis after WWII.
