The first was created by the writer-artist team of Joe Simon and Jack Kirby in Marvel Mystery Comics #13 (Nov. 1940), published by Marvel predecessor Timely Comics during the 1930s-1940s period fans and historians call the Golden Age of Comic Books.
The second and most longstanding is an android (also referred to as a "synthezoid" in the comics) who was a member of the superhero team the Avengers. The character was created by writer Roy Thomas and artist John Buscema in Avengers #57 (Oct. 1968). This version was apparently destroyed in Avengers vol. 3, #500 (Sept. 2004).
The Vision starred with fellow Avenger and wife the Scarlet Witch in the limited series Vision and the Scarlet Witch #1-4 (Nov. 1982 - Feb. 1983), by writer Bill Mantlo and penciller Rick Leonardi. This was followed by a second volume numbered #1-12 (Oct. 1985 - Sept. 1986), written by Steve Englehart and penciled by Richard Howell. A decade later, the Vision appeared in a solo limited series, Vision, #1-4 (Nov. 1994 - Feb. 1995), by writer Bob Harras and penciller Manny Clark. Nearly a decade after that came a four-issue second volume (Oct. 2002 - Jan. 2003), written by Geoff Johns and penciled by Ivan Reis.
The robot Ultron is the creator of the Vision, a type of android he calls a "synthezoid", for use against Ultron's own creator, Dr. Henry Pym (Ant-Man/Giant Man/Goliath/Yellowjacket) and Pym's wife, Janet van Dyne (the Wasp) of the superhero team The Avengers. The Wasp is the first to encounter the synthezoid, and describes it as a "vision" while trying to escape. Adopting the name, the Vision is convinced by the Avengers to turn against Ultron and becomes a member of the team. The team believes the Vision's body was created from that of the android original Human Torch, while the patterns of his synthetic brain were based on those of the then-deceased Simon Williams (Wonder Man). The Avengers later learn that the time lord Immortus used the power of the Forever Crystal to split the original Human Torch into two entities: one body remained the original Torch while Ultron rebuilt the other as the Vision.
When the Vision attempts to penetrate an energy field erected by the villain Annihilus, he "shuts down" and even after regaining consciousness weeks later remains paralyzed and assumes a holographic form. He eventually regains control of his body and become team leader, Having become unbalanced by these events, he attempts to take control of the world's computers. With the aid of the Avengers, the Vision is restored to his normal self, but now closely monitored by a coalition of governments.
Rogue agents of the United States government, manipulated by the time traveler Immortus, abduct the Vision and dismantle him. The Avengers recover the parts, and Dr. Pym rebuilds the Vision but with a chalk-white complexion. The revived Simon Williams, however, does not allow his brain patterns to be used again to provide a matrix for Vision's emotions, explaining that the original process, done without his consent, had "ripped out his soul". Although Williams' own love for Wanda leads him to feel guilt, he justifies his actions by claiming the Vision was never anything but a copy of him, a claim that a number of other Avengers, including the Wasp, accept. This, along with damage to the Vision's synthetic skin when he was dismantled, results in the synthezoid's resurrection as a colorless and emotionless artificial human.
The original Human Torch also returns from his own apparent demise, casting doubt on the Vision's identity. The Vision and the Scarlet Witch's children are then revealed to be fragments of the soul of the demon Mephisto, who had been broken apart by Franklin Richards shortly before the birth of the twins. The twins are absorbed back into Mephisto, which temporarily drives Wanda insane. Although she recovers, Wanda and the Vision separate, each operating on a different Avengers team.
The Vision gradually regains his emotions by adopting new brain patterns from deceased scientist Alex Lipton, and gains a new body that resembles his original. In addition, Simon Williams' brain patterns gradually reemerge and meld with Lipton's patterns, restoring the Vision's full capacity for emotion.
Shortly after a reformation of the Avengers, the Vision sustains massive damage in the final battle with the sorceress Morgan Le Fey, and although incapacitated for several weeks is eventually rebuilt and recovers. While recovering, the Vision gives up his attempt to reconcile with his wife. Remaining a member of the Avengers, he briefly becomes romantically involved with teammates Carol Danvers (a.k.a Warbird/Ms. Marvel) and Mantis before attempting again to reconcile with the Scarlet Witch. Grief over the loss of the twins, however, again drives her insane. She tried to rewrite reality to recreate them, causing a series of catastrophic events that includes the Vision crashing an Avengers Quinjet into Avengers Mansion. The Vision advises his teammates that he is no longer in control of his body and then expels several spheres that form into five Ultrons. The Avengers destroy them, and an enraged She-Hulk tears apart the remains of the Vision. The Avengers later believed that Ultron may have put a command in the Vision that would have been activated by the Avengers' Code White alert.
When Iron Lad leaves the time period, he leaves the armor behind with the Vision's operating system activated. Upon Iron Man's examination, it is determined that although the Vision has all of the physical and emotional potential of the original, he lacks the first Vision's vast experience. Moreover, whereas the first Vision's brain patterns were based on Wonder Man, the new Vision's brain patterns are based on those of Iron Lad.
While more advanced than the original, the Vision is unable to join the reformed Avengers due to their concern that he is still being controlled by Kang. The Vision then acts as a mentor to the Young Avengers, and also changes his appearance from his Iron Lad-like appearance to that of the original Vision to comfort Iron Lad's former crush, Cassie Lang, the Young Avenger known as "Stature" and daughter of Scott Lang During the events of Civil War, the Vision opposes the new Superhuman Registration Act, and sides with Captain America by joining the Secret Avengers. Vision plays a major role in the final battle, disabling Iron Man's armor.
After the events of the Civil War, the Vision travels the world posing as different people for a better understanding of who he is. He then finds Cassie and declares his love and states he is now called Jonas. During a later battle between the alien Skrulls and the Avengers, the Vision is shot through the head. He is revealed to have survived, and joins with Nick Fury and S.H.I.E.L.D. alongside the other Young Avengers.
