That’s actually where it started.  Scroll Scribe/Darnell suggested an image of AJ molting out of her pony skin as a changeling drone or queen.  I drew it, really like the design I did for the changeling part shown, and the eyes reminded me a lot of Chrysalis so the idea of an evil, corrupted applebug has been eating away at me ever since.  I’d need to come up with a regal name for her though.
