J.O.C.A.S.T.A.

J.O.C.A.S.T.A. is a back-up natural-language user interface created by Tony Stark.

History
When Tony Stark was looking through a collection A.I. chips to find a replacement for J.A.R.V.I.S., who had been uploaded into the Vision, one of them was marked "J.O.C.A.S.T.A.". Instead of choosing J.O.C.A.S.T.A., Stark opted to choose F.R.I.D.A.Y.

Trivia

 * In the comics, Jocasta was the robotic bride of her creator Ultron. Like Vision, she betrayed him and became a member of the Avengers.
