I keep looking at the comments on https://www.youtube.com/watch?v=3VQS-egMTLk and keep getting more and more worried and angry that so many people looking at that video think that the ideas are stupid and are all re-skins. I think the part that I'm most annoyed at is the fact that I can't do much to change it.
I just realized the similarity eye-wise between Necronomitron and the Moon Lord. An eye on each hand, and one on the forehead. Perhaps they're related! What if Necronomitron's the Moon Lord's skeleton?
