As a sequel to the original marvel comic, Regeneration one shows us some loose ends to be tied up like the nucleon, headmaster process, The Ark etc. But one thing that I have wondered that may never be explained in the comic, is which autobots are still living and which dead? The main reason this has me confused is the fact that after the 21 years the last autobot has been around probably reviving every autobot. However I don't quite get how characters like perceptor are around when he along with dozens of other autobot corpse were apparently left on earth. It seemed to me like the autobots went straight back to cybertron from klo without even checking up on them, So did the last autobot drop down by the Ark and just revive every autobot on board and not doing anything about Megatron Starscream or Shockwave? Or are all those autobots on the Ark still dead and perceptor was actually just one of those revived by nucleon. I may be the only one on this boat but it kinda frustrated me not knowing which character may be dead or alive.
