It was a space cartoon, sort of like a cross between Star Wars and Battlestar Galactica. Lots of star fighters and aliens. Here are the major things I remember:
The main villain used to be a good guy but was left for dead and rebuilt by the bad guys. This is shown in opening. He is bald, wears a mask and a cape and has a thing on his chest (I think). I think he forgot who he was ultimately a puppet?
The second notable bad guy was a robot that looked very similar to the bug people that Vegeta kills in Dragon Ball Z. In one episode the good guys find his head covered in something in a crab tank.
The bad guys use vehicles that have legs and I'm sure they called them crab tanks.
In one episode some Jabba the Hut look-a-like absorbed the leaders of the good guys and the bad guys in to his body so they feel what he felt.
One of the good guys is like a werewolf but in reverse. Whenever he is on his planet he looks like a normal human. And his wife or girlfriend lives there.
The opening explained the show; bad guys attack, one of the good guys is captured and turned into a Darth Vader-ish leader of the bad guys.
Can't remember much more, will add if anything comes to mind.
