In the original toy lines, cartoons and comic books there were many factions of Transformers. To date, in Micheal Bays previous three Transformer movies have shown us more than just the two battling sides of the Autobots, led by Optimus Prime, and the Decepticons, led by Megatron - In Revenge of the Fallen we were introduced to the Fallen AKA Megatronus Prime; the founder of the Decepticons, we were also introduced to the Constructicons and their combined alter-ego; Devastator.
Yet, as one would imagine from a franchise that is over 30 years old, there are many, many more factions that can be brought onto the big screen. Transformers: Age of extinction features but one such faction - the Dino-Bots. Others that could appear in future movies include the ravenous Insecticons, the Spy Changers, the Terrorcons, the Omnibots, the Predacons and so many more.
