Mercy

Mercy is a mysterious Marvel entity who first appeared opposing the Hulk, possessing the ability to grant death to those who genuinely desire it — making her an enigmatic, morally ambiguous figure rather than a straightforward villain.

Born from the legendary creative partnership of writer Peter David and artist Todd McFarlane, Mercy made her Marvel debut in The Incredible Hulk #338 in 1987 — right at the heart of the Copper Age, when that title was becoming one of the most daring books on the stands. She's a figure whose presence has lingered across nearly four decades, sharing pages with some of Marvel's most iconic names: the Hulk himself, Bruce Banner, Ben Grimm, Matt Murdock, and Logan. With a key-issue debut and a place of honor in the celebrated Hulk Visionaries: Peter David collections, Mercy is a testament to how that era's Hulk run rewarded readers willing to explore its stranger, more philosophical corners — a character well worth seeking out for any serious collector of the period.
