Perhaps I'm playing too much Pokemon when I start combining aspects of it with Star Wars in weird dreams that would be nice setups for books.
Though, I can't really say that the dream was really Pokemon-influenced that much. It borrowed names and a very basic design motif for the aliens. Everything else, such as the socio-political structure of the Trevenant race and the shape-shifting warlike behavior of the invading Zekrom, were more influenced by various EU and other scifi that I've read over the years.
