pics after bio Gravel Allegiance Autobot Function Rescue, ground removal, assault Quote “If it stands in my way, I’ll tear it down.” Gravel is a bit of an oddity among the A.D.C.U. He simply showed up one day after a large battle and began to help the Autobots and pull humans from the crumbled buildings. The very odd part was how much his face and voice was similar to Prime. After the day was over he asked Prime for permission to join the A.D.C.U. and Prime gladly agreed. After a few weeks a Mixmaster showed up and tried to attack the A.D.C.U. but before he could get his hands on Grime, Gravel had snatched him with his powerful arms and made quick work of him. Gravel refuses to carry a firearm and fights with a tenacity that makes the Autobots thankful he is on their side. Perhaps one day they will find where Gravel came from and learn what turned him into such a fierce warrior.
