Hmmm, lets see the largest Autobot. Prime about 15 tons, the SR-71 about 34 tons. Combined 49 tons. One Terrex RH400 excavator rolling around in a bad mood tearing through highway overpasses, 1,080tons. One cranky critter walking out of the ocean if based on a Soviet Delta sub, 13,500tons. The Autobots in a fight are going be like fleas on a pitbull.
