True, but the pre-Friends version was "The Amazing Spider-Man", so I think it still applies...

It's a hard question! I'm not even going to reply to those on Twitter who answered with stuff like "Thundercats"... THAT'S NOT A SINGLE CHARACTER NOR IS IT SATURDAY MORNING AAAAAARGH!!!

I considered "Dark Rider" from Turbo Teen, my favorite unrevealed villain of all time... but the more I think about it, it's got to be either Teebo from The Ewoks, or Teddy Ruxpin...
