The Black Terror - Volume 1 - Bookshop Edition

Introducing The Black Terror, Nemesis of Crime! Bob Benton was a pharmacist working on a tonic to pep people up, who developed "formic ethers" instead, thanks to a comment made by his new assistant Tim Roland, inspiring him along a new path. Inhaling the vapors from his discovery granted him superhuman strength, which he used to become the crimefighter the Black Terror, battling hoodlums, saboteurs and enemy agents in equal measure. Tim, similarly empowered, became his sidekick, together known as the Terror Twins!
