Huffer

When Huffer finally returned home to Cybertron, most Autobots figured he would never again venture any further than the construction mines of Iacon. When it was revealed that he had agreed to join the crew of the Graviton, nobody was more surprised, or impressed, than Optimus Prime. Maybe it was because there was little work to do on his newly rebuilt homeworld, or maybe he had become accustomed to having what he built destroyed. Regardless, he had decided to leave Cybertron again and to use his skills in a new venture.
