Main Character: Richard Henry Benson, a super-strength crime-fighter known as "The Avenger."

Sidekick: Fergus "Mac" MacMurdie.

Inspiration: Benson's character drew heavily from popular figures like The Shadow and Doc Savage, combining their traits to appeal to fans of those successful series.

Promotion: In August 1941, WHN linked the radio show to Street and Smith's magazine, The Avenger, through eye-catching red posters displayed at newsstands.

Main Character: Jim Brandon, a biochemist who becomes The Avenger.

Innovations: Brandon uses a Telepathic Indicator and a Secret Diffusion Capsule to aid in his crime-fighting efforts.

Comparison: This version was often seen as a budget-friendly counterpart to The Shadow, sharing similarities in narrative style and character traits. For instance, Brandon, like The Shadow, had a beautiful assistant, Fern Collier, who knew his true identity and helped him in his missions. Brandon also used "a black light of invisibility" and could interpret "thought flashes."
