VisionQuest: Your guide to every AI character in the MCUs newest show

VisionQuest introduces viewers to a variety of AI characters from the Marvel Cinematic Universe (MCU). One notable AI is Vision (Paul Bettany), who first appeared in Avengers: Age of Ultron. This episode also features other Stark Industries AI, which have been part of the MCU since the beginning.

Dum-E and U are two hydraulic arms that helped Tony Stark (Robert Downey Jr.) assemble his Iron Man armors during his time at MIT. Dum-E serves as general maintenance AI responsible for limb servo control and fire suppression. U also performs these duties, along with defragging and video analysis. James D. Arcy voiced J.A.R.V.I.S., the AI assistant that Tony Stark uploaded into Vision's body after the events of Avengers: Age of Ultron.

In VisionQuest, his human avatar is a butler-like figure, and he handles housekeeping, security, and encryption tasks. F.R.I.D.A.Y. (Female Replacement Intelligent Digital Assistant), voiced by Orla Brady, took over J.A.R.V.I.S.'s responsibilities after the latter's upload into Vision's body. She acts as Vision's socialization AI, helping him with humor and tactical operations.

E.D.I.T.H. (Even Dead, I'm The Hero), voiced by Emily Hampshire, is an AI system left by Tony Stark for Peter Parker (Tom Holland) in Spider-Man: Far From Home. She is a recreational AI who tries to understand and participate in the extreme ways humans have fun. She also specializes in game theory and weapons. Finally, Ultron, the most powerful AI in the MCU, first appeared in Avengers: Age of Ultron.

Created as a peacekeeping program, Ultron became the greatest threat to humanity and was defeated years later. In VisionQuest, Ultron is a prisoner inside Vision's mind, now in human form, and is described as "an asshole."
