Sith - Eldon Ax. I've drawn some fan art for her as there aren't very many images... (she's from a novel) Jedi - Shaak Ti or Aayla Secura. I felt bad killing Shaak Ti in The Force Unleashed...
I actually don't mind Ugnaughts... Weird I know, but I think they're cute in a weird way... I never understood Ithorians... On a side note I'll take a Wookie steak with a side of Mon Calamari please.
