[Bane had an inkling of what the person he thought of as Anakin Skywalker was doing but but the Sith may be in for a surprise since the bounty hunter chuckled softly instead of gasping for air. You didn't deal with multiple Force users, many in the Dark Side, without being prepared. Not only was he mentally resistant to the Mind Trick, his breathing tubes had a variety of purposes - they did filter toxic air on certain planets but they also gave him some defence against Force choking. That might not be the case indefinitely, if Vader persisted with it, but for the moment it was having little to no effect.]

If you are trying to do what I think you're doing then it won't work, Jedi.
