Hmm... Well, I very much appreciate the efforts so far. But I know it wasn't Buck Rogers, Space 1999, Voyagers, or Space Rangers. It might have been Jason of Star Command--that is, that's the closest in appearance to what I remember--but I'm not certain.

Ah, well. I knew it was a long shot, given how little I remember.
