J.A.R.V.I.S. (Just A Rather Very Intelligent System)
J.A.R.V.I.S. is an artificial intelligence created by Tony Stark,a.k.a,Iron Man.
Just A Rather Very Intelligent System (J.A.R.V.I.S.) was originally Tony Stark's natural-language user interface computer system, named after Edwin Jarvis, the butler who worked for Howard Stark. Over time, he was upgraded into an artificially intelligent system, tasked with running business for Stark Industries as well as security for Tony Stark's Mansion and Stark Tower. After creating the Mark II armor, Stark uploaded J.A.R.V.I.S. into all of the Iron Man Armors, as well as allowing him to interact with the other Avengers, giving them valuable information during combat. During the Ultron Offensive, J.A.R.V.I.S. was destroyed by Ultron, although his remaining programming codes unknowingly continued to thwart Ultron's plans of gaining access to nuclear missiles. His remains were found by Stark, who uploaded them into a synthetic body made of vibranium and, in conjunction with Ultron's personality and an Infinity Stone, an entirely new being was made: Vision. J.A.R.V.I.S.' duties were then taken over by F.R.I.D.A.Y.
