The overlord is built out of a big egg. I got it from Micheal's. It was a set of 3 nested, glitter infested eggs. If you go back to a my post a few days ago, the dropship gallery has pics of the whole build. If you have any questions please let me know.
I have a big foam ball for a union, I have had it a few years now, but I have a backlog of other projects to finish.
