So, what all do we think about Ratchet's role in DotM? It was revealed that he works with Optimus Prime in the beginning while Bumblebee, Sideswipe, Wheeljack and Mirage are on a seperate mission. I also believe that he flies to the moon to help Prime revive Sentinel Prime (Whether he actually does anything up there is unknown.) He participates in the final battle aswell, but I'm not sure exactly what he does. My guess? Point and shoot, hopefully use his saw a time or two and fix somebody. I really like Ratchet, and I hope his role is increased in this movie. He seems to have a new weapon, some sort of flame thrower that he uses in the trailer when Prime swoops in. Ratchet also has a brand new paint job, and is included in Wave 1 of the deluxe figures, which hopefully says something about his significance in the film. It sounds to me, as far as roles go, Ratchet will have a decent amount of screentime. The doc-bot doesn't get enough love in these movies, so my main desire for him is to have at least 6 lines and fix somebody onscreen.
