Devil-Slayer (Eric Simon Payne)

Eric Simon Payne is presented in Marvel Comics as a former member of a demon cult called the Agents of Fortune, who "helped him unlock the psionic potential of his brain" and "gave him a mystically created dimensional cloak." He later turned on the cult, adopting the sobriquet Devil-Slayer and operating as an occult-focused vigilante and monster hunter within Marvel's layered cosmology.

Depicted as a costumed, human vigilante who wears a mystically created "shadow cloak." The cloak has been shown in differing designs across appearances (later stories note a revised costume). Sources emphasize the cloak as his distinctive gear; other visual details vary by issue and re-design and are not exhaustively specified in the available summaries.

Payne is a trained soldier and former hit man proficient in hand-to-hand combat and nearly all forms of weaponry and an above-average marksman. He wields a mystic shadow cloak that elongates and responds to his mental commands, forming whip-like or grappling appendages. The inner surface of the cloak serves as a portal to other dimensions; by wrapping himself in its folds Payne can teleport to and from other dimensions and could even teleport limited distances on Earth by entering and exiting at different locations. Sources also state that time runs differently inside the cloak. Use of the cloak is physically taxing and can exhaust him, with narrative accounts describing him fainting when its power is spent and at least one review reporting a depiction of fatal strain in a specific issue (accounts vary).
