The Hangman first appeared in Pep Comics #17 (July 1941), published by MLJ Comics, a forerunner of Archie Comics. The Hangman's story begins with the Comet. Chemist John Dickering gave himself super powers of flight and eye beams through a chemical he injected into his body. In Pep Comics #17, the Comet was gunned down by a criminal, a tragedy witnessed by his brother Bob. Vowing vengeance, Bob became the Hangman and tracked down the murderer.
Unlike his brother Bob, the Hangman had no superpowers, but he was a skilled fighter and used a hangman's noose silhouette symbol to strike fear into his targets. He never seemed to outright kill criminals, but drove them to confess out of fear or accidentally die due to their panic.
In some stories, the Hangman barely appears, showing up later in the story to deal justice to a hapless murderer. In some respects, the Hangman points the way to the pre-code crime books by EC.
For the Hangman miniature, I started with a Red Guardian Heroclix, and added a cape and a rope belt.
Though the heroic brothers never had a chance to work together, here they are side by side. The Comet was a much earlier project, an easy repaint of a Cyclops 'clix.
The Hangman and Comet's golden age comics are in the public domain can be found at the Digital Comics Museum. Next time, a magician and his assistant.
