In the very early development of J.J. Abrams' take on Star Wars episode 9, the "Big Bad" was going to be a massive starship that would land on a planet and "terraform" it into a Death Star-like industrial surface, chewing through the existing natural resources (and existing civilization) as it inexorably circumnavigated the globe. This was the first thing that I worked after starting on the project, and I envisioned it as a massive anvil of a ship that opened up into a chevron-shaped planet vacuum that worked its way Roomba-like across the globe, levelling mountains as it went.
