Yami o Makumono (Spreader of Darkness, often called Darkness or Yami o for short) is the lead villain, though he takes his time to arrive.
Stargazer is the one controlling things for most of the series. Kali with her Psi Whip and Brain are the lead stooges. According to Rail the Lost Ships are the bad guys, but I won't put them here and I don't have cels of them anyway. (Yes, I heard there were some Lost Ship cels. They're not all CG!). For that matter, some people perceive Rail as a bad guy. I only perceive him as convinced that he knows what he's doing, though.

Comments: Yami o Makumono. I had been looking at this cel in the series and thought "Ooh, that'd be a cool cel to get!" Then I got it and promptly forgot where I had seen it. Oops. I needed to cut off the top of his hair to get this cel done in one scan.
