Hauler (called "Hauler" in his one appearance) joined Ratchet and Cliffjumper in recovering Hound from the bottom of a ravine. He never spoke or transformed to robot mode. He was also yellow, which made him look like Grapple. Later, during a spiritual journey through the Matrix of Leadership, Rodimus Prime was shown a vision of eight Constructicons creating Megatron. The identities of the two extra Constructicons remains unknown, though quite possibly one might be Hauler.

I would like to know, because, I have no idea.
