Krona is a renegade and former member of the Guardians of the Universe and an enemy of Green Lantern. As a scientist, Krona was obsessed with finding the origins of the universe in which his search consequently led to the birth of evil itself throughout the universe, and the creation of the multiverse. Krona was created by John Broome and Gil Kane, first appearing in Green Lantern (Volume 2) #40 (1965). ||
