During her transition from toy to her animated form Evil-Lyn lost something.

When comparing Evil-Lyn to her toy counterpart, there are many obvious differences; such as her much lighter skin complexion, and the addition of a cape. But one difference that can easily slip by is the lack of the skull atop her headpiece. Interestingly enough, Filmation originally designed her to sport the skull. Layout artwork, and originally model designs show drawn with the skull. It is presumed that Filmation scrapped the skull motif due to the additional (unnecessary) time it would place on the artists involved.

In this layout drawing from "Colossor Awakes" we can see where the artist has been notified that the skull motif is to be dropped, as the red pencil appears to have been erased to an extent.

When referring to specific stock animation sequences the layout artists would sometimes copy stock pencil artwork. Here (on the left) we can see a familiar shot of Evil-Lyn in pencil, the skull being removed at a later point. And finally (on the right) going by the color scheme of the toy here is what Evil-Lyn probably would have looked like with the skull atop her headpiece in final animated form.
