Krona Kruneeghol belonged to the ancient Maltusian race and, as a scientist, sought to create intergalactic order, believing the only logical way was through knowledge. His thirst for understanding consumed him as he implemented perverse experiments to the detriment of the cosmos. Krona's ideas often clashed with those of his fellow Maltusians, including his protest over his brethren's contempt for emotions during their progress into becoming the Guardians of the Universe.
