You Have The 'cons But Add Eviler 'cons?? - Tumblr Posts

Transformers Cybertron Au?

What would happen if at the end of (or during) Cybertron. The Decepticons opened a warp gate and met a more sinister version of themselves that start wrecking havoc all over the place?   

Maybe have who knows how many identity issues, both versions of Megatron arguing, or the Autobots trying to figure out how this even happened and how to get the other ‘cons back to their world?

Anybody got any other ideas for this au????
