Could anyone help me with my memories of this series? I'm looking for a series that I remember these things from:
The main villain, or one of the main villains, reminds pretty much of Darth Vader, but his brain is visible, it is inside a dome on his head.
The same villain battles the hero, or one of the heroes, and falls down a volcano. I don't remember if he survived, but shortly after that, a female version of this villain is revealed (like his sister or something?).
The whole series is animated and takes place in space and on different planets.
The main character/hero is either looking for his father, or his father is lost somewhere in space.
The team is made up of the usual Star Wars-clones (i.e. one Luke, one Solo, one robot).
Now, I might of course mix separate cartoons into one, but the strongest memory is the villain falling into the volcano. I'm pretty sure it is not G-Force, although Zoltan fits quite well. It is probably not Jayce and the Wheeled Warriors too, because the Monster Minds don't quite fit the profile (at least of what I can remember).
I am also not sure if this series had a toy line or something. One thing is for sure: it did not come after the year 2000.
