I dunno, soul maybe? A family doing knock-off Einzbern work?

Soul is distinct from the body in a person's makeup, same as the mind is.
The skin one also including hair really does knock out an obvious choice, huh.
Super Reproductive System
One of the families can just do Medb's mass birth an army thing.,
Literal Shit Magecraft, now that's new
One form of making homunculi in the old alchemy stuff involved dung actually

Given the other aspects of the body, the best thing I can think of is organ magic. Either that or cell/DNA magic. Though I doubt the latter one, given how DNA is a relatively recent discovery.
Hair?
It goes into skin.
maybe magic circuits themselves
Unlikely, and it would defeat the purpose anyway, since Atlas alchemy was developed on the assumption that traditional magecraft was going to become extinct.

Well there it is. But I wonder if Ergo is modeled after him, or if he is him.
Timeline makes sense for it to be him. Have they ever explicitly stated that his base self is human, or could he be some kind of clone/homunculus?
I like Ruo, and I do hope he makes it through the story in one piece
Probably won't though, he has "tragic rival" written all over him. I do expect him to turn on Ziz at some point though, probably for Akira's sake.
