This question already has an answer here:
So... me and my friend have been arguing ever since Avengers: Age of Ultron was released. He thinks that Vision is literally just Jarvis in a new body. But I disagree. I think that Vision is an entirely new entity. ...let me walk through this
So Ultron tries to make a perfect synthetic body for himself and uploads a good bit of himself into the body... then Tony and Bruce get ahold of it and try to upload Jarvis into it (they start to but it's ruined by Quicksilver). Then Thor (after seeing visions of the future and the world being destroyed by the mind stone) brings Vision to life with an electric hammer bash.
The Vision then wakes up and is confused about where he is. After a brief fight scene he is changing his appearance...and talking.
From the Transcripts Wiki:
Steve Rogers: Why does your "vision" sound like JARVIS?
Tony Stark: We... we reconfigured JARVIS' matrix to create something new.
Steve Rogers: I think I've had my fill of new.
Vision: You think I'm a child of Ultron?
Steve Rogers: You're not?
Vision: I'm not Ultron. I'm not JARVIS. I am... I am.
So... in that last line Vision stated that he is NOT Jarvis. Yet my friend still states that Jarvis is the Vision. And I have argued back as well as I can but he won't budge. But I feel that fact is...that Vision (although he has some ofJarvis that he was made up of) is an new entity and is not "controlled" by Jarvis (like the way Jarvis can control the Iron Man suits).
This is a very raging argument and im slowly being beat down by a lot of nieve people agreeing with him. And I would appreciate a lot of feedback on the matter below. So is Jarvis the Vision?
