Barring the name recognition for sales, would a Transformers series be successful without Megatron or Optimus Prime as the lead characters? Beast Wars had characters that were decidely not the original Megatron or Prime, and that was rather good, wasn't it? Robots in Disguise doesn't have to be about Megatron or Prime, instead the Car Robots Gigatron and Fire Convoy. Animated Prime was Optimus Prime in name only- and that was pretty interesting. Could a Transformers series work without the big names?
