As the Emperor of the Imperium is confined to the Golden Throne I don't think he can put up much of a fight vs anyone at the moment.
Sorry not jedi wielding guys ( I've got a jedi and I'm not afraid to use it!!) ligtsaber wielding guys I meant.... They're some on palpatine's side in the new game....why would they be with the empire????? i dont think that palpatine would allow them to join his army hed probably kill them if they tried
