A sarcastic, ill-tempered robobrain that defines everything that's problematic with trying to use a human brain for an organic processor. As part of the Mechanist's fleet of robots attacking the Commonwealth, Jezebel was leading one of the task forces until their unfortunate run-in with the Rust Devils. Captured and dismantled, Jezebel was reduced to a mere processing unit interrogated by the Devils' mechanic. Forced to put up with functional morons (albeit technologically talented morons!), she yearns for a chance to get into a new chassis and get the hell out of Boston.
Without revealing too much, resources spent on Jezebel will not be wasted, so there's no need to try to be stingy.
Quests
Headhunting: Jezebel is the third radio beacon necessary to crack the Mechanist's encryption. Once salvaged and removed from the hangar, she provides the necessary code - but in order to crack the Mechanist's lair, the player has to construct a body for her.
Jezebel is reference to the same one from the Bible. The reference is further alluded by being found with another machine named Ahab, who was Jezebel's husband. Jezebel even has a similar personality to the biblical version, including being self-centered and arrogant.
