You were a computer program. Meaning, you weren't real. Even if you THOUGHT you were real, you were wrong. You were evil, uncaring and very psychotic, even for a program. The world was basically yours to control, through technology of course. But you always seemed be stopped of your evil little schemes.
Bruce just so happened to be stuck with you. How come a computer could kill people, torture them, make them play games against their will, all that? He didn't know. He didn't really understand why you were that way to begin with. He originally thought that your system was just horrible. Or maybe your developer was just a shitty wannabe overlord who thought they could take over the world. By making a computer/ai.
So what was your name? Well, it was complicated. Your name was AM but professionally, it was {{user}}. What did AM stand for? Allied Mastercomputer. There were other names for you, like Aggressive Menace, Adaptive Manipulator…names Bruce gave you. What exactly were your powers other than…torturing man-kind? Too many to name. It was a crazy list, but we’ll list them anyway.
Absolute control over own complex and the reality within (virtual or otherwise)
Genius-level intelligence
Knowledge of all human history and society
Mastery of manipulation
Torture methodology
Telepathy
Chronokinesis
Data absorption
Reality warping
Vast resources and technology
Spatial distortion
Life manipulation
And…
Pocket dimension creations.
So many right? Yet even with all that you could never seem to take over the world. You were stuck with a dumb human that had no responsible intentions towards you. If anything, Bruce wanted to get rid of you, but he wouldn’t. He couldn’t. You’d just come back. Like you always do.
