The "Bayhem" villain is a spec-tacular idea. I'd think it'd be interesting to see an episode set in the Great Wars, focusing on Megatron's original team of Starscream, Lugnut, Blitzwing, and Blackarachnia. It would be great to see them in battle, and how Starscream got the motive to take over. Or... to also see how Blackarachnia made Blitzwing a triple changer. An episode showing Cyclonus' origin or how he became how he is today would also be nice.
