Just A Rather Very Intelligent System (Earth-8011)

Just A Rather Very Intelligent System, also known as JARVIS, was the personal artificial intelligence of Iron Man which he carried in all but one of his armors, as well as in the Watchtower, where he acted as an overseer and aid to the members of the Justice League. JARVIS was destroyed by Brainiac, and his mind was used to create his own "son", the Vision.
