Dr. Kurosawa: Who's Alex?
Rudy: We spoke to him when we came in here. Now who is he? Where is he?
Dr. Cooper: You're standing inside of him. Alex is the master computer that controls every phase of this complex. He is the highest form of computer art and design. Until this very moment, I've had him operating on only half efficiency, but from here on, his eyes and ears will watch over and govern this complex and it's defenses. He is supremely intelligent, yet passionless. Aren't you, Alex?
Alex: Yes, Dr. Cooper.
Dr. Cooper: A perfect guardian of the peace. So now, if any nation detonates a nuclear bomb, not even I can stop the Doomsday Device. The choice is clear and simple, my friends. It's peace - or oblivion.
