That second series of Voltron I am talking about is commonly referred to as Vehicle Voltron. I am uncertain as to exactly when this series made it's appearance, but it did air shortly after the run of the first season of Lion Force Voltron. I am also uncertain as to how many episodes were in this Voltron though it did only seem to have a single season run. Voltron reappeared in I believe, 1988 in syndication on the USA Network. Also, Voltron LionForce was briefly picked up by the Cartoon Network in 1997/98. It's second season ran at the same time in limited markets as "The New Adventures of Voltron." The Vehicle Voltron has yet to make a reappearance in over a decade
The Mighty Morphin Power Rangers ripped off Voltron completely. The same number of characters, the same type of robot that form from the five of them. But of course we all know which is the better show. Wink!
