10. Computron
Hasbro/TakaraProbably the most science-based of Transformers characters (at least from the original Generation 1 cartoon), Computron is a combiner comprised of the Technobots, who were built by Grimlock. Yep, that Grimlock. In the season three episode 'Grimlock's New Brain', Grimlock becomes highly intelligent to the point where he very handily builds some new Autobots. The reason Computron is at the bottom of the list is his lack of action, which in the Transformers world can be seen as a major setback. Computron has an annoying habit of slowing battles down to compute the outcome of the battle itself. Nevertheless, the individual Technobots could transform into several Cybertronian-based vehicles, and thus their designs would lend themselves very well to any artist with a keen eye to spruce Cybertronian designs up for any future Transformer movie.
