Scent of Finality

Cybertron, 2007. AlutronVegeta has begun his campaign to reconquer Cybertron for himself and the Decepticons. His ultimate goal: universal domination. The war has progressed to the very threshold of Iacon. The city itself has been locked down and under siege for 2 months. Optimus Prime and his Autobot warriors within are in the war room devising a tactic of getting out from under the siege when Perceptor issues an urgent call to the room. "Optimus, Im forwarding a hologram to you of something rather strange going on about 30 miles out in space from Cybertron.", Perceptor gasped out rather hurriedly. The hologram flickered above the briefing table, showing either a dimensional gateway or a transwarp portal opening in the middle of space. "What is it Perceptor?" Optimus asked. "Based on preliminary scans, Prime, it appears to be a rift in time and space, possibly a dimensional tear as well. Im still monitoring it." "Whats the urgency of this rift Perceptor?" Optimus eyes flickered, as if he were rolling his eyes over something that appeared to be trivial. Last time Perceptor called about something this, it was Omega Supreme returning from Nebulon with reinforcements. The hologram flickered, as a change occured in the rift.
Meanwhile, on the outskirts of Iacon, in the command tent of the beseiging Decepticons, I sat with my generals, plotting how to take the city. "Might I suggest, my liege, that we send a strike unit through the underground tunnels? If they take trap detection gear, they should be able to sneak through and open the gates of Iacon." Shockwave suggested. Just the sort of thing I expected him to suggest. As I was considering it, Soundwave came over the com-link. "Sire, theres a dimensional space-time rift opening 30 miles above Cybertron. Possibility of Autobot reinforcements: 45%." And the other 65, Soundwave?" "Unknown, sire, continuing to monitor." I slammed my fist down on the table. SLAG! Just what we need. Either Autobot reinforcements or some damned extra-dimensional being trying to usurp my authoritah. I stepped outside my tent and peered into the night sky. There was definitely something out there.I could see the fabric of space being warped by this rift.
Earth, 3.5 million years ago. Mt. Helena, Oregon. "Hey, boss-monkey, the something wierd out there in the sky." Rattrap reported. Optimus Primal came to the mainroom of their temporary base." Perhaps a ship from Cybertron?" "Negative, its not an energy signature we've encountered before Optimus," Rhinox reporting, turning to face his leader. Meanwhile, over at the Darkside, Inferno was reporting the same thing. "Royalty, strange disturbance out in space. Appears to be a rift of unknown origin." "I am aware of that Inferno. Tarantulas reported that 15 cycles ago. By the pit if you werent so loyal and effective in battle, Id have already slagged you for blatant stupidity." "Megatron, spider-bot reports new update on rift. Asks you to join him in the computer room." "Thank you Waspinator. Now get back to your posts, both of you!"

What is the mysterious rift? What lies in wait in the depths of space, seeking to rain destruction or peace on our observers?

BEST. TITLE. EVER.

I take it you like story too?

Of Course. A word of criticism, why would the all mighty AV stay in a tent instead of a fortress?

Its a seige, those are always done in tents, lol

LOL, 'kay then. Requesting you bring Laser Snarf back.

As all eyes watched the rift, a shadowy figure slowly emerged. A normal Cybertronian sized being, shrouded in shadows w/ deep blue optics. Prehistoric earth and modern day Cybertron both watched in hushed awe as he slowly drew a sword and raised it over his head. The shadow that cloaked him began to fall, to reveal an ancient Cybertronian. Composed of clockwork, gears, and ancient servos, he opened his mouth to speak. "I am Vector Prime, emissary of Primus. The time has come for the final battle between Autobot and Decepticon, Maximal and Predacon."
I flew up into the air a few meters above my tent, intent on speaking with the strange visitor. "Who are you to command us to cease fighting? By what right should you appear to us?" "Cease speaking, AlutronVegeta, all will be revealed in due time. But for now, yourself, Optimus Prime, Optimus Primal, and Megatron II will be transported." His sword glowed a brilliant color of green, and a light encompassed me. I raised a hand to shield my optics, only for them to short out. And then I myself, as mighty as I am, shorted out.
When my systems rebooted, I found myself in an arena domed filled w/ millions of seats. To my left and to my right were multiple Decepticons, some of which I recognized, others I did not. Vector Prime appeared overhead and swathed his sword, revealing a divide that separated us from a score of Autobots, and Optimus Prime. But not just Prime, a whole slew of him, in different forms and sizes. I could only speculate that the Decepticons near me were Megatrons from other universes.
And I looked around the outskirts of the arena, to reveal millions of Transformers seated around us. But what surprised me most was what floated in the sky high above us. A giant being, immeasureable in size, floated there. His blue optics looked down on us w/ sadness, and a he opened his massive maw to speak to us.
"My children........."

Requesting that this be a battle to determine the ultimate bot of all time.
