*grins* A shame I wasn't planning on bringing in Macross until far later. The Valkyries would actually look down on most regular transformers. They could hang out on the launch deck. (Jetfire, for example, is a Vaklyrie stolen from the Macross series)

Don't forget, this is a realm of infinite possibility. Perhaps this Megatron is the one defending Cybertron from the villainous depredations and resource mongering of the evil Optimus Prime or maybe Energon is a substance that grows in the presence of various radiations or power sources? You can mix it up a fair bit though... getting too far afield just feels wrong to me. For example, mirror universe Star Trek seems fine to me... but the previously mentioned Warhammer Space Marines riding My Little Ponies through the depths of space atop magical rainbows is a bit much for my taste :)
