Prologue
He had been floating through space for years, at best he could guess. How many he was unsure of, but years nonetheless. He had reduced power to his chronometer what seemed like an age ago. He was low on energon, the source of his power. He had barely enough left to function. The end would come soon, he knew that, but something had recently begun to nag at him from the depths of his memory banks. Some distant memory that had been forgotten, or possibly erased from his data store. He couldn't say what it was, strangely he couldn't remember, but something was definitely bothering him and it wasn't that he was going to die. Something in the space around him made him think these thoughts. He was sure he had been here before. He again scanned his memory core but came up empty, but something was definitely...there in front of him, how could he not have seen it? Admittedly he had reduced power to all his systems to a critical level in order to save power, and thusly his life, but how could he have missed THAT? In front of him he saw a giant... spaceship? Or perhaps a space station? Whatever it was it was huge and yet vaguely familiar. Could it be that he had been here before? It was possible that his memory had been damaged when his ship had exploded those many years ago but still, how could he have forgotten this?! It didn't matter anyway, he would soon be out of power and this, whatever it was would remain a mystery. Just then his onboard energy detectors finally picked up the monstrosity before him; it definitely had energy on board, and a lot of it. If he could somehow get into it he could refuel and then he might actually be able to use his memory. But how could he get in? And even if he could get in would he have the energy to find a suitable refuelling area? And if there was anything on board this massive hunk of metal in space would they not try and stop him accessing their power supply? As he contemplated all these he suddenly noticed that he was surrounded by some form of energy beam. It seemed to be dragging him towards it. Whatever it was it wanted him inside. As this realisation dawned on him he suddenly wondered whether dieing first might be better as whatever was inside might just be worse than death, but suddenly his systems seemed to shut down and all that was left was darkness.
Was this a dream, or was this death. Stupid thought really. If he was dead he couldn't be comprehending he was dead, he would be with Primus. Then he noticed a voice inside his head. A computer he was sure he had heard before, from almost another life. He tried to listen closer but was straining to hear what it said, though he could make out some words. "Brain scan comple...identification confirmed. Damage te...port to...". Again he blanked out, whatever it was he could perceive little of what was around him, and yet he felt safe. Almost comfortable in this, whatever it was. Again he heard the sound of the computers monotone "nergise unit in 5,4...1, energising". Suddenly all his systems came back online. His memory cleared. He knew where he was in an instant, everything was clear again. A wry smile spread across his cat-like face. Soon he would get his revenge. Soon all would know and tremble in fear at his name and the name of his comrades and leader. "Computer report" he commanded. The computer replied quickly and efficiently "all stasis chambers still on-line. Prisoners still contained within chambers 20, 21, and 22. Reactivation of troops will commence on your report". His smile grew broader. Soon the Maximals would have something proper to fear. They would suffer for reprogramming him, they would suffer for the pain he felt in the depths of space, and Cybertron would be returned to Primus's true children. With that he transformed into cassette mode and inserted himself into the waiting information slot and downloaded the program that would reactivate his colleagues. After millions of years they would reclaim their home.
