A bit of explanation is required for the first one. The first piece is titled "Heretics." The big gold thing is Vector Sigma. In my story-line, Vector Sigma is responsible for most of the stupidities in the G1 cartoon - for instance why Megatron never blows up Starscream. The major players are programed never to finish the war and are manipulated to keep the sides even and fighting by Vector Sigma. Neither side is allowed to win. Things get ugly when the Autobots find out. The second image is titled "Eclipse"...but that's self explanatory.
