Comics' Greatest World: X

In 1993, Dark Horse launched its expansive "Comics' Greatest World" line with this single-issue debut by writer Mike Richardson and artist Lee Weeks, introducing a new corner of the publisher's superhero universe. The series centers on a mysterious, powerful hero known only as X, whose violent methods and shadowy origins set the tone for the darker, more grounded take on costumed adventurers that defined the imprint. Though brief, this foundational issue established a key figure in Dark Horse's shared superhero landscape, showcasing the publisher's ambition to build its own distinct mythology outside the Big Two.
