There is a Yondard-AU I've tooled around with with a friend of mine. This is more than a mere 'split timeline', as there are some notable alterations in characters and how Yondards work in general (mainly procreate. AU Yondards can, Base canon Yondards cannot).

Due to these changes, Ziggy, in this form, cannot occur in the base story. She doesn't have much as far as her own story but what led to her birth is a bit complicated.

She fashions her outfit after the Black Maw guards, but isn't really one herself. She has, as seen in another picture, met some other Ziggy's, and is among the upper tier in power compared to other Ziggys (Z.Calypsa or Mouse Ziggy could both do more, but B. Ziggy is more capable as a fighter.

As to what she is... she's a mix of a lot of stuff.
