 Voltron was not a straight dub from the Japanese anime due to  American broadcast standards. One of the most noticeable differences  involves the character Sven. In the Japanese version, Sven died  after battling Haggar in episode 6. In the American version Sven was  seriously injured and left to heal. He returns near the end of the  series. In the Japanese version, this was his brother at the end of  the series.
