Jack of Hearts #1

Jack of Hearts #1 was released in 1984 as a self-titled four-issue limited series published by Marvel Comics. The character, created by Bill Mantlo and Keith Giffen, had first appeared in The Deadly Hands of Kung Fu in 1976 and spent years as a recurring guest star across various titles before headlining his own publication. This series served to consolidate the character's complex origins and tragic narrative, centered on Jonathan Hart and his struggle to control the lethal zero-energy that transformed him.

The series featured art by Jerry Bingham, whose work on this run is often noted for reflecting the high-stakes, dramatic tone of 1980s superhero fiction. The narrative delved into the science-fiction elements of Jack's dual heritage as a human and an alien from the planet Contraxia. While the character remains a niche figure in the broader Marvel pantheon, this debut issue of his solo series is valued by collectors for its role in rounding out the deep bench of Marvel's cosmic-adjacent heroes from that era.
