I think I remember reading that those tubes attached to Cad Bane’s face were a way to counter-act a Force-choke? I guess the idea was that even if his throat was chokes the tubes would still deliver whatever gas he needs to breathe to his brain. Although that might work with a Jedi, I can’t imagine a Sith or Dark Force User not crushing or tearing them away though.
Well then, here’s one answer. But then again, Jedi and Sith are not the only Force users in the galaxy…I imagine Cad Bane had some interaction with some others to make him act on such a precaution.
