Dark Nova (ダークノヴァ, daa-ku-no-va) is a mysterious supernatural entity from outer space who sides with the Decepticons against the Autobots. Known as the "Ultimate Emperor", he revived Galvatron, upgrading him into Super Megatron, and later merged with him to become the Star Giant. He commands armies of Novaroid drones and Galaman troopers, which make up the bulk of his forces. Note: The English name "Star Giant" is actually a translation from the Japanese kanji 星の巨人, hoshi no kyojin. "Giant of the Stars" would also be an acceptable translation.
