Vrak was a high-ranking member of both the Warstar and The Armada's alien royal family who served as the primary antagonist of both Power Rangers Megaforce and the supporting antagonist Power Rangers Super Megaforce. As the younger yet more competent son of Emperor Mavro, his brilliant tactical expertise was put to use under the command of Admiral Malkor during the initial Insectoid attack against Mega Rangers. After his defeat, he was resurrected as a cyborg and later returned to fight the Mega Rangers in his true royal form.
