Villains from the Transformers toy-based franchise, which includes several cartoon series, the live-action films by Michael Bay, and various comic books. This includes the TV shows, Live action movies, Video games, and other spin-offs of Transformers, such as; Beast Wars, and Beast Machines. These are mainly Decepticons, Predacons, Vehicons, and even humans who either have a xenophobic nature towards the Transformers and seek to eradicate them, or side with the Decepticon for their own selfish reasons. But this category fits in with any villain, provided they originate from the Transformers multiverse.
