Krona

Krona was an ancient scientist from Oa whose reckless experiment to witness the birth of the universe unleashed evil across all existence. Condemned by his own people, the Oans, for this catastrophic act, he became one of DC's most consequential cosmic villains and a cornerstone of Green Lantern mythology.

Few characters make their entrance in DC's legendary Who's Who: The Definitive Directory of the DC Universe — that landmark Copper Age reference series that defined the sprawling DC cosmos — but Krona did exactly that in 1986, introduced by the great Len Wein. Over nearly three decades, this figure carved out a place in the DC universe alongside titans like Hal Jordan, Superman, and the Green Lantern mythos, appearing most prominently in Green Lantern and Secret Origins, the very series dedicated to stories that matter. With a key issue to their name and a presence that stretched from the Copper Age well into the Modern era, Krona is the kind of deep-cut DC figure that rewards the curious collector who ventures beyond the headlines.
