Besides Cybertronians, the only other races who take part in the war are humans and Nebulans, but that's it. Do the Transformers have allies and enemies besides theirselves? Isn't there a neighboring planet who would fight for either the Autobots or Decepticons? We have seen there are other races besides the 3 I mentioned, but are there more? Why wouldn't they take a stand in a battle that been around for millions of years?
