Ace

Few Modern Age debuts carry as much quiet charm as Ace, who first haunted the pages of The Dark Horse Book of Hauntings back in 2003, brought to life by the creative pairing of Mike Richardson and the incomparable P. Craig Russell. A Dark Horse original through and through, Ace keeps remarkable company — sharing adventures with the likes of Hellboy himself, as well as fellow travelers Whitey, Orphan, Rex, and Jack across titles like Hellboy / Beasts of Burden: Sacrifice and the collected Beasts of Burden Omnibus. With over two decades of continued presence stretching into 2025, this is a character whose staying power speaks for itself — small in catalog footprint perhaps, but clearly beloved enough to endure.
