Getting stranded on a remote, empty world to serve as a spy and sneak-thief for Optimus Primal wasn't high on his list of priorities for Rattrap. Smart, sneaky and sarcastic, Rattrap often rubs other Maximals the wrong way. He' never been to keen on lobbing artillery around like the others; a stand-up fight just isn't his thing. Give him the chance to bust into a Predacon base and snatch some juicy data though, and that's when he really shines.
