User blog comment:The Awesome Jack/Was this supposed to be Vilgax in Omniverse?/@comment-3441048-20140302180907

I think it was supposed to be. They actually showed more concept shadow images of Wildvine, Dr. Animo, Grey Matter I think. Apparently they were preparing for an Original Series continuation but they must've still been deciding on an animator when they released the series details, concept art and title. Vilgax obviously looks different from the shadow image above.
