Why did Alfred try to use knock-out gas to stop what he knew was a robot? It's no wonder he got taken down!
Rossum: You don't understand. You're not a man's mind in a robot's body. You're a robot. Period.
Bat-Duplicant: You're lying! It's not possible! I know my family and friends! I remember names, faces, birthdays! I have memories! A past!
Rossum: You have information. Data. Nothing more. Do you remember your first kiss? Your favorite song? The last time you tasted a really good steak?
Bat-Duplicant: No, but-
Rossum: Can you remember anything beyond cold, hard facts? Facts can be implanted, accessed from any number of sources.
Batman: Busy night?
Commissioner Gordon: Never to busy to spend time cutting down our piñatas. Next time try hanging them a little lower, if it isn't too much trouble.
Batman's duplicate: I cannot function as the Batman until you are deactivated.
Batman: That's easier said than done.
This episode is episode 6 on the Batman: The Animated Series Volume 3 DVD.
This episode originally started as a concept to use in "Heart of Steel, Part II "with Batman fighting a robot version of himself. The idea for the episode was scrapped and the final product became this episode.
Rossum's Ultimate Robot
Dr. Karl Rossum, the inventor of HARDAC, gets his name from the play R.U.R. (Rossum's Ultimate Robot), written by Karel Capek in 1920. This play is where we get the word robot. In our terms, a robot is some machine that works automatically. In the play, however, a Robot (from the Czech word "robota" meaning "servitude" or "drudgery") was more like what we would call a genetically engineered worker.
