I was wondering, what the heck makes a character change into a Batsu Character instead of a generic X-Character? For example, Dia's first form we see is Batsu (or X) Dia. Yet when other guardian characters change they become normal run of the mill X-Characters.
Same goes for Nazo Characters, like Nazo Cecil. Nana is the only other guardian character who has an opportunity to do this and she just goes back into her egg.
Also, what determines what they look like? It seems to me like they try to reverse the colors or something, put on weird eyes, and make them have blank expressions.
In that vein, I thought I would try to make one, so I tried making "Batsu Miki". The main thing I note is I have no artist implements nor a bag that might hold them, so this might not be complete.



Does this look convincing as a so called "X-Miki"? What would other Batsu or Nazo Guardian Characters look like?
EDIT:
Added darker skin for comparing. I am trying to darken it without turning her into a pumpkin like Batsu Dia.
