Valzorr was a prince of the planet Korvia. Framed by Prime Minister Zoxxo for the murder of his Aunt and Uncle, the King and Queen of Korvia, Valzorr escaped to Earth. There, he nearly drowned in the ocean, but he was rescued by Supergirl and taken to Midvale Orphanage under the name Johnny Blank. Supergirl later helped him return to his home planet and clear his name. ("Supergirl's Darkest Day!")
