S03E23: Only Human

After the Autobots interfere with one of his plans, Victor Drath gets help from Ol' Snake (none other than the notorious Cobra Commander) to create artificial human bodies. Rodimus, Springer, Ultra Magnus and Arcee get caught and placed in the artificial bodies. Seemingly human, they will have to find a way to reverse what was done to them and stop Drath from using their original bodies against Autobot City.
