 In episode 0.01 "More than Meets the Eye, Part 1", an orange Autobot  in the form of a truck crane appears briefly to haul Hound up for  repairs. This Autobots only appears in this scene, never speaks or  transforms to robot mode, and is referred to as "Hauler" by  Cliffjumper. Apparently, this was an early version of the Autobot  called Grapple, who later appears in season two.
