I've always found Zygarde very similar to Dunsparce, probably because they're both snakes and underground. Dunsparce, being frail and small would very much like to be big momma Zygarde. *Sparkle* *Sparkle*
This is pretty funny consider how Zygarde's 0% form is pretty much dunsparce if he was green. I guess the fans finally got their wish of giving that damn thing an evolution or whatever.
