ED-4

ED-4 was a slicer droid who was one of the three droid brains that made up the computer of the starship Millennium Falcon. The other two were known as V5-T and L3-37. Long before the Millennium Falcon was known to Lando Calrissian or L3-37, the droid's consciousness was uploaded onto the ship to join V5-T, who had been the first to join the Falcon.
