Batman: Alfred!
Alfred: Yes, Master Wayne?
Batman: Did you install the new security system yet?
Alfred: I believe so, Master Wayne. It is a Genetic Lifeform and Disk Operating System.
Batman: I'll go test in now.
Batman, all geared up steps into the basement, where he keeps his best gadgets and the new security system.
What Batman saw was a complete surprise. The computer hacked into his computer and was downloading top-secret info.
Batman( in deep, croaky voice): Who are you? What the heck are you doing?
GLaDOS: I am GLaDOS. Thank you for the information on all your gadgets. I shall sell them on the black market. Unless you will try to stop me...
And so the battle begins. A stealthy detective vs a killer AI computer system.

Batman immediately threw explosive gel at GLaDOS. He dove behind a table and flipped it over for protection.
BOOM! No effect on GLaDOS. It barley managed to blow a little metal off.
"Get comfortable while I warm up the neurotoxin emitters." said GLaDOS as poisonous gas started to leak through the room. "Whoops. Looks like I can't control these turrets anymore." Turrets emerged from the ground and began shooting the table.
Batman rolled to another table and took out his cryptographic sequencer. If only there was some way to distract GLaDOS...
That's it! thought Batman. I'll use my electric Batarang to stun her and plug the cryptographic sequencer in.
Batman rolled and threw his batarang. Stunned, GLaDOS said "Look, your wasting your time. And believe me, there's not a whole lot of time to waste." Batman ran up and was about to plug his device in when he noticed something: The system didn't have any place to plug in. She only had four cores.
Breaking out of stun, GLaDOS swung her head and knocked Batman back. A turret hit him, and falling to his knees, GLaDOS finished him herself, crushing him with her head.

GLaDOS wins
