Thanks again everyone for the comments. This is supposed to be a fun story (sorry, those looking for angst), so have fun with it.
I was a bit surprised that the superpowers granted him muscles like that. It never occurred to me, especially with LnC-based Superman, that muscle power was involved as much as superpower.
There's a method to my madness, here, that will be explained a few parts down the road. It's not the muscles so much as the fact that the powers kinda sorta become a part of him.
I'll post more tomorrow. Until then, thanks again for reading.
