Here is a fabulous rendition of Xerian as a dragon Synth - being a dragon is one of his fondest wishes or dreams. I'll have to see if I can work this into the followup story someday because he looks absolutely awesome.
Though not having hands anymore would present practical difficulties, and I don't know how it would affect his relationship with 'Zuki.

This was drawn by  KristKC who loves drawing dragons and seems to be particularly awesome at drawing robotic ones. I'll link to her original when it's posted. EDIT: https://www.furaffinity.net/view/51401242/
The Synth species was created by  Vader-San.
