Like the title says, which one is your favorite old Autobot? There's Ironhide, Alpha Trion, and Kup from G1. There's Rhinox from Beast Wars There's X-Brawn and Railspike from RID. There's Scavenger from Armada There's Landmine, Vector Prime, Brakedown, and Backstop from Cybertron There's Ratchet, Ironhide,and Jetfire from Movieverse There's Ratchet, Ultra Magnus, and Alpha Trion from Animated. I say Rhinox since he was such a compelling character and he had the best weapons in the series: chainguns of doom.
