Devil's Due G.I. Joe vs Transformers continuity
Cobra dug dozens of Autobots and Decepticons out of their four-million-year resting place and began rebuilding them into a Cobra-controlled army. However, with Wheeljack and Bumblebee's help, the mind-controlled Transformers were awakened, and the very cheesed-off Constructicons, including Long Haul, descended upon their previous captor, Doctor Mindbender.
Soundwave stopped them from killing the doctor, however, as he was needed for other purposes. Instead, the Constructicons were ordered to protect the SPS Satellite controls from the attacking Autobot and G.I. Joe troops. To do so, Long Haul combined with the others to form Devastator, but the giant was soon defeated by the attackers.
