"I just remembered, they tried to install an artificial intelligence subroutine when the station went operational. They shut it down right away because it didn't work right."
- – Michael Garibaldi
Sparky the Computer is an artificial intelligence personality that was installed onto the Babylon 5 mainframe computers shortly after completion in 2256. The A.I. was an experiment and proved a complete failure, as the personality was stubborn, uncooperative, and "emotional."
Sparky was taken offline and remained that way until 2260, following Babylon 5's declaration of independence during the Earth Alliance Civil War, when Michael Garibaldi accidentally reactivated the files in which Sparky was contained. Sparky was disabled again a few hours later, as soon as it became possible to do so.
- The name "Sparky" is never explicitly stated in the episode, but appears in the credits.
- Sparky was voiced by Harlan Ellison.
