What was the outcome of the fight between the fight between you and Galvatron after you both perished in the physical world?
Ah, that truly was a story for the ages! It'd be easy enough to simply tell you all that occurred—how I was victorious, and that with the victory hard won, I retired to the Realm of the Primes. But I feel that the outcome was not so simple as all that, and that you deserve to know the whole story of what transpired between the two of us.
With my last act in the mortal plane being to bequeath my sword to Optimus Prime, my spark was allowed to pass on to the greater beyond. However, as the Guardian of Space and Time, I was still connected to the timestream, and it was there that I felt a disturbance.
As he had done thrice before, Galvatron had turned a defeat into a means to survive. You will recall that after seemingly being destroyed once, his essence persisted thanks to the Armor of Unicron. That power, combined with the temporal energy his spark absorbed from my blade, allowed Galvatron to transcend as I had. But where I was the Guardian of Space and time, he set out to be its Conqueror.
We clashed many times. Each blow sent ripples through time and space. Across multiple streams, fates were altered, events were given new destinies, and others were split asunder merely by the clashing of my Rhisling against his Death Calibur. We became locked in a stalemate, until Galvatron decided not to attack me, but rather, time itself.
Across the time stream, Galvatron's voice reached his past self, telling him of his ultimate fate, of Unicron, of the true nature of Mini-Cons, the Super Energon, the power of the Cyber Planet Keys—all of it, every power he would one day seek to attain. This, as you might imagine, gave the Megatron of the past an advantage, and he took quick action to seize the opportunity. It was only by reaching out to the past version of Starscream, who was yet untainted by years of Megatron's cruelty, that I was able to stop Megatron from gaining dominion over Cybertron.
I was then forced to use my power to splinter these events off into a new timeline—one where Starscream took Megatron's place as the new leader of the Decepticons—rather than allow a new future to overtake the old. In doing so, I allowed my nemesis, Galvatron, to slink away from my gaze in order to scheme again another day.
Even now I still feel his presence in the timestream. I fear he is learning to manipulate time in more subtle ways—making incremental changes, and studying the repercussions, rather than altering events drastically. But for now, his menace has subsided, and I am free to wait here for when he might emerge again, answering all your questions.
Nevertheless, one question weighs upon my spark. Be he Megatron, or Galvatron, one thing that has been proven again and again is that even death is no obstacle to him. Each time he has seemed to have met his end, he has emerged from the brink of oblivion, stronger than ever before. And so I wonder... if Galvatron meets his end, by my hand or any other, will it truly spell his demise? Or will it simply grant him another opportunity to exploit, and transcend to greater heights? Or is the answer to quelling his threat to instead find the twisted sliver of honor that once existed in his spark—the one that led him to honor his soldiers' memory and sacrifice himself against Unicron—and reaching him in some other way?
One thing is for certain, at least: I have not seen the last of Galvatron by any means.
