There is a flash of light, and everything is different.
Somewhere, far away, he hears something about a biolink, and a mega system, but he's too lost in the power flowing through him, energizing every aspect of his being. He can feel his clothing fading away into nothingness, yet he does not feel naked, for as it vanishes, the touch of a skintight jumpsuit replaces it. Over that, a great weight seems to settle over him, yet he is strong now, and it feels almost as if it is not there.
The changes are not all above the skin, either. He can feel his body changing, feeling more alive, and yet more robotic all at once. He can practically feel the metallic coating his skeletal system is receiving, and if he could see his skin, he is sure that whatever is being added to his bloodstream is glowing brightly enough to map out his circulatory system.
Then, the light fades, and he is back in the real world.
He is different now, his clothing replaced with armor. Green and white plates of metal rest comfortably on a body far stronger than any soldier has a right to be, and his hair, dyed green, flows halfway down his back. He can feel the pistol resting comfortably at his hip, but he knows he does not need it. Not against these men.
Against these men he has a better solution.
He has a visor now, little more than a glorified pair of shades, but a visor nonetheless. Readouts that he shouldn't understand make perfect sense to him, providing him with real time updates on his system's status and operational time.
It also has the ability to slide away in one place, a slit just big enough for his eye to see out of unhindered.
He knows that he must do this, as naturally as he knows how to breathe, in order to use his power.
As he makes eye contact with the guards, his speaks, and it is as though another is speaking with him.
"I, Lelouch vi Britannia, command you, now all of you, die."
And as he knew would happen, the guards, in perfect unison, raise their guns, and with a chorus of "Happily, your highness!" they commit suicide.
He does not move, not for several moments. Then, he speaks.
"What is this power?"
"I have given you the power of the King," the voice from before replies. "The power of Biometal."
"Who are you?" he asks. He suspects he already knows, but he'd like to hear it for himself.
"You can call me Biometal Model C."
