D.A.V.E.

Created by Hugo Strange, Digitally Advanced Villain Emulator or "D.A.V.E.", is an AI that has the brainwaves of several Batman villains

History
Due to its brainwaves, it can correctly guess most of Batman's moves, and can imitate other villains', such as the initial acrobatic feats the Joker was capable of accomplishing or Catwoman's agile gymnastic routines, or the Penguin's mastery of martial arts, making him a tough opponent to battle hand-to-hand. Its robotic body is light, resilient and flexible enough to take on Batman on far more than equal terms. D.A.V.E. is as intelligent as the Riddler and Hugo Strange, giving it the psychological advantage; it can hack into any computer and control every machine it encounters. This frankenstein was allowed to unleash itself upon Gotham by Strange programming it to "escape" from Arkham, and allowed it to lure and study The Batman. Though he had set the ultimate trap for Batman in the Batcave- having deduced Batman's identity via an elaborate process of elimination, D.A.V.E. set up a trap which would either expose Batman's identity or kill Alfred-, D.A.V.E. hadn't planned on Batman using reverse logic on D.A.V.E. He was defeated when Batman questions D.A.V.E's own origins as D.A.V.E doesn't have an actual origin, even being unaware that he is a computer program. Although D.A.V.E. knew of the origins of others, he didn't know the origin of himself--or even that he wasn't even human. After Batman told him this, it bought him enough time to crush D.A.V.E. under the giant penny.

D.A.V.E. makes a second appearance in the spin-off comic book The Batman Strikes! in issue #34, "Shtick Shift". D.A.V.E. is revealed to have survived his last encounter with Batman, but he is damaged, not remembering how he survived, and frequently glitching up. Also, out of all the brain waves stored in him, he only acts as the Joker and Riddler. He participates in a constest with Riddler to see who can capture and unmask Batman. D.A.V.E. and Riddler are defeated by Batgirl and Robin, when they track the villains down in order to save Batman.

Role in Ultima
In Ultima, D.A.V.E.'s deactivated body was found by the Mad Doctor, who reprogrammed the AI to serve him as a member of the Circle of the Blot. D.A.V.E.'s knowledge of villains from the Organization has proven useful to the Shadow Blot's plans in that he now knows their secrets, their strengths, their weaknesses,...and their inevitable fatal flaws.
