A new crime-fighting tool - D.A.V.E. (the Digitally Advanced Villain Emulator), a computer program designed to think like a supervillain - causes trouble when it escapes and starts to act out on its knowledge.
Tropes in this episode include:
- A.I. Is a Crapshoot: Guess. Subverted. Hugo Strange programmed him to be evil in the first place.
- Armor-Piercing Question: Batman asks D.A.V.E. his Origin Story.
- Awesomeness by Analysis: D.A.V.E uses this to figure out who Batman really is. First he narrows down the pool by the amount of people in Gotham who have both the fitness and the wealth to be Batman. Then he narrows it down to Bruce by asking "Who would have the motive [to become Batman]?".
- Card-Carrying Villain. D.A.V.E.
- The Chessmaster: D.A.V.E. is never surprised by anything Batman says or does - until the end.
- Do Androids Dream?: Neither Alfred nor Bruce seem to think of it, but not recognizing that he was a computer program could be a sign that D.A.V.E. was sentient.
- Gone Horribly Wrong: What D.A.V.E. appears to be.
- Ironic Echo: "Every superhero has an origin." So should every supervillain.
- Multiple Choice Past: When D.A.V.E. is asked by Batman what his origin is, he discovers he just has a lot of contradicting backstories taken from previous supervillains.
- Sadistic Choice: Employed and Lampshaded by D.A.V.E - save Alfred or save his secret identity.
- Take a Third Option: Bruce attempts to do this instead. Unfortunately, D.A.V.E. anticipated it.
- Shout-Out: D.A.V.E is in many ways this to 2001: A Space Odyssey.
- Tempting Fate: When being informed that Strange's computer believes it's a villain, Commissioner Gordon asks how it could it enact its plan if it doesn't have a body. Turns out getting a body is its first plan.
- Title Drop: Numerous times by D.A.V.E., since he fancies himself as this, plus one by Professor Strange at the end of the episode.
- Villainous BSOD: D.A.V.E., when Batman tells him he's a computer and he realizes he never considered the possibility.
- What Could Possibly Go Wrong??: Yeah, keeping around a supercomputer that think it's a supervillain. Let's see how that works out. Except that was exactly what Hugo Strange wanted.
