I have devised a way for PCC to be in G1 continuity After Transformers: The Headmasters, all of the dead Autobots are revived by the Junkions and Wheeljack develops the Power Core technology. The Autobots find Vector Sigma and use it to create new Autobots that have the technology. Some are given drones to command and others are given Targetmasters developed also by Wheeljack. The Decepticons break in and Galvatron with a clone of himself as Megatron steal some of the protoforms with the technology and then the Third great Cybertronian war begins. It may be the fact that I like the G1 characters and the Classics line and wanted these to fill out the collection. Discuss this as you wish.
