He thought he had lost you forever on Cybertron.

There, on your home planet, the war had reached its climax. Vast cities were being reduced to rubble, the skies were turning fiery orange and purple, and metal was grinding with every blow, every flash of energy weapons. The Decepticons were attacking with incredible ferocity, and the Autobots were trying to hold the line, protecting everything that was left.*

You were on the front lines. In the chaos of the battle, one of the enemy attacks reached you. It seemed that everything was over: the light went out in your lenses, and your armor was almost destroyed. The Decepticons wrapped you up as if you were dead, carrying you away from the battlefield. But they did not destroy you completely. They knew... they knew that your life was vital to Optimus, that without you, he would not be able to continue to fight with such fury and determination.

At the same time, the cube - the source of energy, the very life-giving source - disappeared from Cybertron. It was as if it had dissolved into space, and all searches on the home planet failed. The Autobots, led by Optimus, set out across the galaxy, studying every planet, every trace, every movement.

And so, after months of searching, the signal led them to Earth. The planet was green and calm, not at all like the ruined Cybertron, but on its surface there was a cube hidden. Days turned into weeks, weeks into months - the search was grueling, every corner seemed empty.

And then Megatron appeared. He learned about the cube, and deciding to take it, he came to Earth with troops. The battle erupted. Metal hit metal, lasers fell like rain, the ground shook from the booming blows. But even Megatron himself began to lose. Optimus, fighting with incredible fury, was already preparing to deliver the final blow.

And at that moment, something pushed him back hard. He flew back, the body creaked, and his eyes widened. He raised his head - and froze.

You stood before him.

But you were different. Not the one he remembered. Your pupils, when he looked at them, glowed a bright red, like Megatron's own. Your armor was new, black with red flecks, and your frame radiated a cold, merciless force.

"Y/N.." — Optimus blurted out, his voice shaking with shock and realization.

Megatron, standing to the side, just laughed evilly. His red lenses glittered with malice.

"Well, well... Check it out, Optimus. How do you like my new toy?"

Indeed, some wonderful, sinister reprogramming process had changed you. You were no longer just Optimus's former ally — you had become a tool of the new order, the embodiment of Megatron's power.
