He’s a Kaleesh that was transformed into a cyborg. Pretty much the only parts that remain of his original body are his eyes, brain, and the rest of his organs.OK. Basically another Vader with more stuff damaged/replaced. Since the lung obviously doesn’t work properly either, I would have replaced that as well.
If the lung itself is the force bearer that might be the reason to keep it.
Silly, but… well.
He’s not force sensitive, so that’s a good point. It’s clear the lung wasn’t working correctly, so they should’ve replaced it.
Why even keep the lungs if he can clearly survive in space without them?
Maybe he held his breath.
