I can't actually remember, does everyone (but Shen Wei) only have one power? If that's what canon says, then yeah maybe some level of dark energy bolt is considered more just a biological fact of life than a power per se.

I can't believe that looking different would have the chance of being quite as common a power, if only because there are instances when I would have expected Dixing fugitives to use it, instead of just going around with their regular face. And Zhu Jiu wouldn't need his crunchy wig. :D

But then, the Regent is one of only three official Dixing leadership roles...maybe the appearance-changing is endemic to the role, not the person?
