Vision

"You're unbearably naive." "Well… I was born yesterday."

- Ultron and Vision

Vision is a powerful, synthetic being born from a Vibranium-laced body created by Ultron and Helen Cho, programmed by Tony Stark and Bruce Banner using J.A.R.V.I.S.-based codes, and activated by the Mind Stone that was hidden inside the Scepter. Originally conceived as the perfect form for Ultron, Vision was repurposed when Tony Stark and Bruce Banner implanted J.A.R.V.I.S.-based codes into his mind, granting him a benevolent personality and a fondness for humanity. This led him to joining the Avengers to stop Ultron. After the Ultron Offensive, Vision formally became a member of the Avengers under the leadership of Captain America.

Creation and Siege
"The regeneration Cradle prints tissue; it can’t build a living body." "It can, you can. You lacked the materials."

- Helen Cho and Ultron

During an attempt to create a more powerful body, Ultron manipulated Doctor Helen Cho to use the Cradle for the creation of his new body. Under the control of the Scepter, she used the machine to create the body, combining artificial organic tissue with Vibranium samples that Ultron had stolen from Ulysses Klaue. When the Avengers arrived aiming to stop him, Ultron was forced to flee before he could finish uploading his mind into the body, knocking out Cho and killing her staff in the process while his only allies, the Maximoff twins, betrayed him upon realizing his genocidal intents. During a chase through the streets of Seoul, the Cradle was juggled around until it was recovered by the Avengers and taken to Avengers Tower in New York City. Upon examination, Tony Stark chose the idea of repurposing the body rather than destroying it like the majority of the team desired would be a more beneficial choice. He convinced a reluctant Bruce Banner to help him achieve this, and together, the two uploaded the recently recovered J.A.R.V.I.S. A.I. into the body.

Part of a Vision
"We have to act now. And not one of us can do it without the others. Maybe I am a monster. I don't think I'd know if I were one. I'm not what you are and not what you intended. So there may be no way to make you trust me, but we need to go."

- Vision

As the procedure of installing J.A.R.V.I.S. neared completion, Captain America, Quicksilver and Scarlet Witch returned to the Avengers Tower and a violent dispute erupted over this second attempt at creating a true A.I. At the last moment, Thor arrived and sent lightning from Mjølnir into the Cradle. The electricity sped up the development process, bringing the body to life. The being, a humanoid life form with reddish-pink and green skin, was initially confused by his surroundings and briefly attacked Thor. Thor was able to defend himself from the being, who calmed down seconds later. The synthetic then took some time to examine himself before apologizing for its actions and then offered its gratitude to Thor before adopting elements of the god of thunder's appearance, unveiling its ability to generate synthetic cells on him by producing a cape and gauntlets. Thor proceeded to explain to the Avengers that the being’s powers were created by the Mind Stone, one of the six Infinity Stones with powers that can transcend time and space. Thor went on to point out that the gemstone which was implanted at the center of the synthetic's forehead was indeed the source of their troubles, and the solution. Captain America and the other Avengers were then understandably concerned about this new being. After enduring much skepticism, the newly anointed "Vision" attempted to deal with concerns about what he was by stating that he was not a child of Ultron. Vision then declared he was not Ultron or J.A.R.V.I.S., rather he was something altogether new and that, unlike Ultron, he had a deep abiding respect for all life. The Avengers, along with the Maximoff twins, remained skeptical as to which side Vision was on, to which the synthetic explained that he was on the side of life while Ultron was not, and then went on to say that Ultron was waiting for the Avengers in Sokovia. He then stated that Ultron would spread his rage and pain all across the globe. Finishing, he casually lifted Mjølnir and offered it back to Thor, much to the bewilderment and surprise from everyone in the room. This action alone was enough to convince the group that he was not hostile.

Preparing for Battle
"Iron Man's the one he's waiting for." "That's true, he hates you the most."

- Tony Stark and Vision

As they prepared to depart for the battle, Vision took time to speak to Thor on the outside of Avengers Tower. While Tony Stark spoke to his team, he mentioned that Ultron was waiting for him; as he walked past, Vision confirmed this by reminding him that Ultron hated him the most. Vision was present alongside the Avengers in addition to Quicksilver and Scarlet Witch while Captain America began his speech on what they will face and that there will be consequences.

Battle of Sokovia
"My Vision, they really did take everything from me." "You set the terms, you can change them." "Alright."

- Ultron and Vision

In Sokovia, as Ultron unleashed his army of Ultron Sentries upon the city, Vision confronted his creator as the activation for the drill emerged from the ground. Ultron expressed his sorrow at seeing that the Avengers had taken everything from him, even his own body he had designed. Vision pleaded to Ultron that he could change all this on his terms, to which Ultron simply replied by attempting to strangle Vision. Vision took the opportunity to hack into Ultron's programming and disable his ability to enter the internet. While the attempt was successful, the process incapacitated Vision, and in a fit of rage, Ultron slammed the synthetic into the ground before activating the key and raising Novi Grad high into the sky.

Assisting Thor
"It's terribly well balanced." "Well, if there's too much weight, you lose power on the swing."

- Vision and Thor

Despite his nearly fatal battle with his creator, Vision was able to recover. Exploring the battlefield, Vision discovered Ultron was attempting to beat Thor to death. Thor distracted the robot with an overlong speech, allowing Vision to strike Ultron away with a hit from Mjølnir before returning it to Thor. The pair took a moment to discuss the weight and balance of the mighty hammer.

Protecting the Key
Vision and Thor destroyed several more of the Ultron Sentries before gathering alongside the rest of the Avengers inside the church, where Iron Man informed them that their mission would be to protect the key at all costs, if it was activated, then the entire city would be dropped to Earth and all human life would be wiped out in the explosion. Ultron confronted the Avengers as he assembled a massive armada of his drones and unleashed them upon the team. A great battle between the Avengers and Ultron's army ensued with Vision contributing greatly by dismembering the Ultron drones using his density-altering powers, working in considerable tandem with the other Avengers as they prevented Ultron and the drones from reaching the activation device. Despite the overwhelming numbers of Ultron Sentries, the combined strength of the Avengers pushed them back and reduced their numbers significantly. Ultron intervened directly and found himself grappling with Vision, the two engaging in a midair struggle. Here, Vision unveiled his ability to fire a beam of energy from the Mind Stone and blasted Ultron away. Soon, Thor and Iron Man joined him as they unleashed beams of lightning and repulsor blasts respectively against Ultron, slowly melting away his shell before they stopped. Weakened and damaged, Ultron was soon punched away by the Hulk. With Ultron's main body seemingly defeated, the remaining Ultron Sentries attempted to flee out of the city, which would allow Ultron to live on through them. Under Iron Man's order, Vision joined War Machine in destroying the remaining Ultron drones, using both physical force and beams from the Mind Stone subdue the remaining robots. Watching Vision's sudden and effective attack in the battle, War Machine was left stunned.

As the Avengers made their way to the Transporters to evacuate, Ultron attacked once again, killing Quicksilver. Driven into rage, Scarlet Witch abandoned her duty of watching the key and destroyed Ultron's main form, allowing one of his few remaining drones to activate the key and drop Novi Grad out of the sky. As Iron Man and Thor prepared to destroy the city, Vision flew to Maximoff's aid, taking the girl in his arms before flying her out of danger.

Destroying Ultron
"A thing isn't beautiful because it lasts. It's a privilege to be among them." "You're unbearably naive." "Well, I was born yesterday."

- Vision and Ultron

By the end, Ultron was able to escape by downloading himself into one final drone body. Vision confronted the drone as it was pulling itself out of the crater where Novi Grad once stood, and pointed out that Ultron was afraid of death. The robot mocked Vision, claiming Tony Stark aimed to create a savior but settled for a slave. Vision didn't deny this, noting that they were both disappointments. Vision stated that the humans are odd, thinking that order and chaos are opposites and that they try to control what cannot be, but they have grace in their failings. Ultron claimed that the humans were doomed; although Vision sorrowfully agreed to this statement, he proclaimed it a privilege to be among humanity for as long as they will last. Ultron responded by calling Vision unbearably naive, but Vision simply smiled and countered by saying that he had only been born yesterday. Angered, Ultron attempted to attack, only for Vision to destroy him completely with an energy beam, thus ending the threat of Ultron.

New Avengers
"Avengers A..."

- Captain America

Vision was recruited formally into the Avengers once the Battle of Sokovia ended, and traveled to the New Avengers Facility along with the other chosen members including Wanda Maximoff, Sam Wilson and James Rhodes, beginning their training under the leadership of Captain America and Black Widow.

Personality
"Humans are odd. They think order and chaos are somehow opposites and... try to control what won't be. But there is grace in their failings. I think you missed that."

- Vision to Ultron

According to Tony Stark, Vision's personality is Ultron's, only without the megalomaniacal aspects. Vision is a polite, calm, and thoughtful being, in a similar manner to J.A.R.V.I.S., shown when he apologizes to the Avengers and the twins after just being brought to life. Unlike Ultron, he values all forms of life. He is also shown to be blunt, when Vision told Stark that Ultron hates him the most. He also likes to reason with his enemies, and will only attack when threatened. However, when he was first created, Vision lunged at Thor, who was the first person he saw, though only because he felt confused about his surroundings as he glanced around.

When Vision encountered Ultron for the final time, both admitted that they cannot understand humans, who are doomed to die out. However, Vision can see the beauty in humanity, due to their potential and imagination, and was happy to serve alongside them. He also regretted having to destroy Ultron, recognizing the latter as "unique" and "in pain", but he ultimately knew that it was necessary, given the great threat that Ultron posed to humanity. Vision showed a great desire to directly protect life, shown when he defended humans from Ultron and his forces, and when he personally saved Wanda Maximoff from Novi Grad's destruction, as it was blown up by Thor and Iron Man.

Powers

 * Synthetic Body: Vision is a sapient construct, a perfect hybrid between organic and inorganic material. His entire body is a mix between a synthetic simulacrum of organic tissue and Vibranium, all of which are enhanced by the cosmic powers of the Mind Stone to function as a living body. Originally, the body was designed to be Ultron's final form. The combination of the vibranium and the cosmic energy from the Mind Stone embedded in his forehead grants Vision a wide plethora of powers.
 * Superhuman Durability: The vibranium composition of Vision's body allows him to withstand attacks of immense force with no visible damage to his exterior whatsoever.
 * Density Manipulation: An ability attributed to the Mind Stone, Vision can increase or decrease his own density at will, allowing him to increase the durability of his physical form or make himself completely weightless. Effects of this ability include:
 * Superhuman Strength: Vision can greatly increase his physical strength to immense superhuman levels by increasing his density, demonstrated by taking down numerous Ultron Sentries in the Battle of Sokovia with his bare hands and grappling with Ultron while he was in his most powerful form. Given his vibranium-enriched flesh, even when his density manipulating abilities are in use, Vision's basic physical strength is still considerably high.
 * Intangibility: Vision can decrease his density and mass, giving him the ability to phase through solid objects. When phasing, Vision can increase his density to destroy the object he phases through from the inside. With this ability, Vision took down numerous Ultron Sentries in the Battle of Sokovia. He even managed to phase his fingers through Ultron's vibranium outer shell.
 * Flight: Vision can minimize his density to its lowest point in order to hover above the ground, granting him the power of flight. He can control his own motion-based force to move through the air at great speeds and instantly stop moving while in the air by completely stopping his kinetic energy and motion.
 * Energy Blasts: Vision is capable of drawing raw power from the Mind Stone to fire beams of intense energy from his forehead. This beam is incredibly powerful, strong enough to cause great damage to Ultron when the robot was in his Vibranium-enriched body, the most powerful of his forms.
 * Synthetic Skin Constructs: Through the power of the Mind Stone, Vision can willfully generate synthetic material. He used this ability to create armor and a cape shortly after his birth in Avengers Tower.
 * Computer Interaction: Vision was able to hack into Ultron's programming and disable the latter's ability to enter the internet. However, the great effort involved in this task temporarily exhausted Vision, incapacitating him for a short time.

Trivia

 * In the comics, Vision was believed to have been created using the remains of the original Human Torch, though it was ultimately revealed to be a duplicate. He later married Scarlet Witch and had two sons, who were ultimately erased from existence, but were reincarnated as Wiccan and Speed.
 * In the comics, Vision was created by Ultron to serve under his command and help him defeat the Avengers, rather than simply being Ultron's final form.
