Mar Novu

Few characters carry the weight of the DC Universe's history quite like Mar Novu, who stepped into comics in 1982's The New Teen Titans #21 — a Bronze Age debut courtesy of the legendary team of Marv Wolfman and George Pérez. Most prominently associated with Crisis on Infinite Earths, one of DC's most consequential stories, Mar Novu keeps extraordinary company, sharing pages with Superman, Green Lantern, Harbinger, Lyla Michaels, and The Monitor himself. With two key-issue appearances to their name and a presence that stretches across an impressive 43 years — touching Wonder Woman and even earning a place in Who's Who: The Definitive Directory of the DC Universe — this is a character whose footprint in DC lore runs deep. For any collector serious about the architecture of the DC Universe, Mar Novu is absolutely worth tracking down.
