I really couldn't say, but it was probably an oldie that got brought over like Speed Racer and later on Voltron. The first anime that I watched and was aware that it was anime was waaaaaay back in the day when the SciFi channel (back when it was SciFi and not Scyfy). They had a Saturday morning anime block and I saw stuff like Akira, Project A-Ko, Venus Wars, and more. I fell in love with Project A-Ko and then Sailor Moon soon came along and that was an obsession. The rest was history. Anime is an obsession from which I have never recovered XD
