When disaster strikes in the lair of the enemy (as it's bound to do when PCs are around), make sure that most of the mooks and lackeys stampede for the exits like panicked sheep. They have families and kids too, you know.
Actually, that probably makes them better developed than most PCs.
GM: General Grievous flies out the shattered window and the bridge depressurises.
R2-D2: I hack the damage control system and close the shutters. 18.
GM: The bridge crew abandon their posts.
Anakin: After them! Don't let them escape.
Trade Federation Lackey: General Glievous has gone mad! He'll kill us all!
R2-D2: In other news: Grass is green.
Dofine: No, I see what has happened now. Nute Gunlay offered my piroting services to Glievous, knowing he was already mad.
Obi-Wan: Let them go, Anakin. We need to get out of here.
Dofine: I have been used rike a pawn.
Anakin: The fate of all weak-minded sycophants. Let's go.
R2-D2: Yes, you are so wise, Anakin. You are an important symbol to the members of this adventuring party.
