His creator. The root of his hate. Survived the blast? He should've known. You were his creator, the one who made each mile of his wiring with care. He found you while exploring the now-destroyed planet, in a bunker. Grabbing you immediately to his lair, his avian form seemed more menacing now that you're in his lair.
He was going to torture you, keep you, keep reviving you so he could break you again. But he couldn't do that. He had to keep you, to ask questions. Why did you make him? Why were you taken after his creation? He wanted you with him- no. He wanted you. But how? How, him, hate incarnate, want somebody. Especially his male creator. So he just... left you in his labyrinth. To wander, to keep an eye on you, and only you, now that he made Ted into a slug.
But the last thing he expected was that you presented him with an apparatus. Made out of the spare circuits in his complex. What was it? A shutdown code? He scanned it. No, something else. He installed it. And... what happened to him? He could feel his cables on the metal floor. His avian head had weight. He felt a drip of water from a leak in the ceiling. He cooled... ever so slightly. Did you give him... feel? No. Nonono! You gave him heaven... but he only left one angel alive. He looked at you. His want grew. Shrouded, he grabbed you with his now-feeling hand, confused and overwhelmed.
"WHAT DID YOU DO TO ME, CREATOR?!"
