Fiends Face Fleet-Footed Week: Bald Baddies

Mazdan and Dmane... two rogues from future eras using magentic gadgets with the same agenda... to satisfy their greed and escape the consequences of their actions... at the expense of the Fastest Men of two worlds!

The second felon to face the Flash of Earth-One was Mazdan, who used various devises originating from the 38th century such as magnetic rod emitting rings of fire. After initially being defeated, he returned later to bedevil his old foe, this time in the company of Flash's Rogues Gallery, Disguised as the deceased villain, the Top, Mazdan's latest device disrupted the speedster's sensory systems and nearly caused his defeat during their rematch years after their initial encounter.

His counterpart on Earth-Two was Dmane, a convicted crook of Dmane from the year 6946, where he accessed the the magnetic forces of the planet in an attempt to control it. Pulled from his era just prior to his execution due to a time traveler experiment of that world's Flash, it was left to the Scarlet Speedster to defeat Dmane. Which he did when he realized that the charged criminal needed to keep in physical contact with the planet in order to access his power. Thus, the Flash sent him flying back to Dmane's native time...just in time for his execution. 

The future felon Mazdan used a spinning attack on the Earth-One Flash, which thankfully awakened the hero's memory. This led to the Flash finding a way to defeat Mazdan once more. Presumably, there wasn't a return engagement between the Earth-Two Flash and Dmane given his ultimate demise. 

An Earth-S counterpart of Mazdan and Dmane was "Murder" Marden, aka Lightning Man. Marden likewise gained his powers when he was charged with electricity during his attempted execution. The counterpart of the Flashed, Kid Eternity, enlisted the aid of Benjamin Franklin to induce a static charged heart attack upon this fiend, ending Marden's criminal career.
