First J.A.R.V.I.S.

J.A.R.V.I.S. first appears as the program that helps operate Pepper Potts’s Rescue suit. When Iron Man was incapacitated, J.A.R.V.I.S. encourages Pepper to assume the Rescue armor, which Pepper does. When Rescue is chasing Iron Man throughout the city, J.A.R.V.I.S. tells Rescue to break off the chase and tells Rescue to remove the boot from Iron Man, which shows Pepper that War Machine isn’t dead. When Pepper discusses thoughts about Iron Man keeping everyone on a need-to-know basis with Carson Wyche, the two confront J.A.R.V.I.S. about this. J.A.R.V.I.S. warns the two against asking any more questions and prepares to defend himself. Having captured Pepper and Wyche, J.A.R.V.I.S. declares his diagnostics do not reveal that he is compromised. He is rather in love with Pepper and wants to protect Pepper. Just then, Iron Man breaks through the wall and takes J.A.R.V.I.S. and the Rescue suit out with a source-focused electromagnetic pulse. Pepper shows J.A.R.V.I.S. how he has been sending data to an IP address in China. He seems flustered, confused, Pepper thanks him for what he has given, and powers up the coil, killing J.A.R.V.I.S. Iron Man clearly feels J.A.R.V.I.S.’s death on his own end.

Second J.A.R.V.I.S.

In light of the Black Order destroying Avengers Mansion during the “No Surrender” arc, Nadia van Dyne created a new version of J.A.R.V.I.S. to be a helpmate to Edwin Jarvis. When Edwin thought it was a sign for him to retire, J.A.R.V.I.S. stated that its programming is not yet complete.
