Archanfel is unique and immortal, ie, no reproduction, plus he is designed as the supreme commander of an army - and I have never seen him eat or drink. I doubt he has genitals, nudity would mean little to him.
Dude, you obviously forgot rule #34, if it exists, there is porn of it. You might not like it, but there are probably tons of fangirls going giddy over a nekid supreme being.
