William Clockwell

William Clockwell is a civilian character introduced in the debut issue of Robert Kirkman's Invincible, moving in the everyday social orbit of protagonist Mark Grayson before Mark's life as a superhero fully unfolds.

Born into the pages of Invincible #1 in 2003 — one of the most celebrated debut issues of the Modern Age — William Clockwell inhabits the vibrant Image Comics universe that Robert Kirkman and Cory Walker built from the ground up. Over a handful of appearances across the series' early years, he shares the page with Mark Grayson, Samantha Eve Wilkins, and the hero Invincible himself, placing him squarely in the civilian orbit of one of indie comics' most beloved superhero sagas. He may not be the one throwing punches, but characters like William are the human heartbeat that made Invincible resonate so deeply with readers — and any collector who treasures that landmark first issue has already met him.
