JARVIS

Just A Rather Very Intelligent System (J.A.R.V.I.S.) is Iron Man's artificially intelligent computer. He runs Stark's home and also communicates with him in his armor, thus giving very valuable information. He also assists Stark in making weapons or armors and gives him details about every person or things that Stark encounters.

History
JARVIS is introduced as Stark's A.I. assistant in his house, controlling the locks and doors and obeying only the voice commands of Tony.
