Ann O'Brien

Few characters carry the distinction of debuting in a San Diego Comic Con Comics one-off and going on to rack up over fifty catalog appearances across nearly three decades — but Ann O'Brien is exactly that kind of quietly enduring Dark Horse gem. Born in 1993 from the creative minds of Mike Mignola and John Byrne, she arrived at the dawn of comics' modern era and found her footing in some of Dark Horse's most celebrated corners, appearing most prominently in Hellboy: Seed of Destruction and the anthology institution that is Dark Horse Presents. She keeps remarkable company — sharing pages with Hellboy, Wolverine, Concrete, and Madman's own Frank Einstein — which speaks to the eclectic, creator-driven spirit that made Dark Horse such a vital publisher of that era. With two key-issue appearances to her name and a publishing history stretching all the way to 2021, Ann O'Brien is a rewarding discovery for any collector who loves digging into the rich connective tissue of the Dark Horse universe.
