Professor Fear (Earth-616)
Professor Fear was a Nazi scientist who was active during World War II. In the fall of 1943 he was located in the United States where he began constructing a sonic device that could shatter the sense of its victims making them his loyal slaves. He hired a bunch of local crooks to steal the special motor needed to make the device operate. However, when a shootout happened during the robbery it attracted the attention of the Human Torch and Toro who attempted to capture the crooks.

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.
