I'd like to think he's flesh only from neck up, everything else is robo, but I dont think thats actually the canon. One could say he'd become one-sided if one arm was enhanced and another natural, there being difference in performance of the limbs, so he could have decided to later make himself symmetrical to avoid sort of pseudo hemi-paresis. He could make this choice willingly as part of accepting his new state?
you are totally right about the lopsided thing! i didn’t even consider that. he does have tubes coming out of the blackwatch skin, which might be filled with some sort of...bone..strengthening...juice? but even then a cyborg arm is probably way more flexible and stronger than human bones/muscles and whatnot. it also makes you wonder where he got the current armor(/operation if he did become 95% omnic), since i wouldn’t think he’d get it from mercy after leaving ow.
