Basically what the title says. There’s always discussions about someone being force sensitive and how they could use the force or not sensitive to it at all, but has anyone ever been completely immune to it? Like if Vader was doing a force choke and the person was just like “why are you holding your hand up like that? What are you trying to do?”
At least using Earth’s atmosphere and gravity numbers, his body isn’t big enough even if 100% of the volume was hydrogen and all his skin and bones were paper thin, that still wouldn’t be enough lift. He wears a leather harness and small satchel among other things.
Also I can’t remember a specific scene but I’m sure he picks up objects at some point, at which he’s have to provide lift from not only his body but the weight of the item being carried.
I know, I’m not upset or anything. OPs question asking about any “force immune” species is a question testing the limits of the fantasy universe. I’m doing the same here for fun discussion.
