Big Zero

Born into the turbulent Dark Reign era of Marvel Comics, Big Zero burst onto the scene in 2009 courtesy of writer Paul Cornell and artist Mark Brooks, making an immediate impression in the pages of Dark Reign: Young Avengers. She's a rare commodity — a character whose handful of appearances carry real weight, sharing panels with the likes of Coat of Arms, Enchantress, Speed, and Cassandra Lang in one of Marvel's more provocative explorations of what it means to wear a heroic label. Her small-but-striking footprint in the catalog makes every appearance count, and for collectors who love the edgier corners of the Modern Age, she's exactly the kind of find worth tracking down.
