Harbinger

A young woman discovered by the Monitor and raised aboard his satellite headquarters, Harbinger was trained to serve as his aide and messenger, tasked with recruiting Earth's heroes for a coming crisis of universal proportions.

Few characters carry the weight of DC's most universe-altering saga quite like Harbinger, who first touched down in Wonder Woman #321 in 1984, a late Bronze Age debut courtesy of Joey Cavalieri and Rod Whigham. With a presence woven through Crisis on Infinite Earths, All-Star Squadron, and The New Guardians, this figure has kept extraordinary company — sharing pages with Superman, Wonder Woman, Green Lantern, and Hawkman across a publishing history that stretches an impressive four decades. Two key-issue appearances signal that collectors have taken notice, and rightly so: Harbinger sits at the intersection of some of DC's grandest, most consequential storytelling. For anyone tracing the connective tissue of the DC Universe from the Bronze Age onward, this is a name worth knowing.
