Vision

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

- Vision and Ultron

Vision is a powerful android born by the result of the synthetic Vibranium body created by Ultron and Helen Cho, and programmed by Tony Stark and Bruce Banner using J.A.R.V.I.S. based codes and activated by the Mind Stone hidden inside the Scepter. However, unlike what he was originally meant to be, Vision became fond of humanity, which led him to join the Avengers to stop Ultron. After the War against Ultron, 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 a machine for the creation of his new body. Under the control of the Scepter, she used a machine called the Cradle to create the body. When the Avengers arrived aiming to stop him, Ultron was forced to flee before he could finish uploading his mind into the being, knocking out Cho and killing her staff in the process while his only allies, the Maximoff twins, betrayed him having seen his plans in the being's mind. After a battle in the streets of Seoul, the Cradle was taken to Avengers Tower. Upon examination, it became clear to Bruce Banner and Tony Stark that the Cradle contained the body into which Ultron had intended to download his consciousness. Stark then pleaded with Banner to help him make one more attempt at artificial intelligence. Banner reluctantly agreed to help Stark upload the recently recovered J.A.R.V.I.S. A.I. into the synthetic body that had been engineered by Ultron and Cho.

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 returned to the Avengers Tower and a 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 cradle exploded open, revealing a humanoid being with reddish pink and green skin. Confused about his surroundings, the being gazed upon Thor. He then jumped on the god of thunder. Thor was able to counter by tossing him out a glass window, but the android was able to stop himself instantly. The android then took some time to examine himself on the reflection of the glass window while also gazing out into the city. The android apologized for its actions and then offered its gratitude to Thor before adopting elements of the god of thunder's appearance, notably the 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 his vision'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. The Vision then declared he was not Ultron or J.A.R.V.I.S. for that matter that 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 the Vision was on, to which the android 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.

Preparing for Battle
"Iron Mans 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, now in his new Vibranium upgraded body, 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 the Vision. Vision took the opportunity to hack into Ultron's programming and disable his ability to enter the net. The attempt was successful however, this hacking ability incapacitated Vision, in a fit of rage Ultron took Vision's body and slammed it onto 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, the Vision was able to recover. Exploring the battlefield, Vision discovered Ultron was attempting to beat Thor to death. Thor tried to distract the robot with an overlong speech while the Vision struck 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
The 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, as 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. While Thor mocked the A.I., Ultron unleashed his entire army upon them, intending to kill them with incredible numbers. A great battle ensued with the Vision dismembering the Ultron drones using his density-altering powers, working in tandem alongside the other Avengers as they prevented Ultron and the drones from reaching the activation device. The Vision ripped through drone after drone and flew around the battle field helping and defending his teammates at all costs. Despite the overwhelming numbers of Ultron Sentries, the combined strength of the Avengers pushed them back. After many of the drones were destroyed, Ultron attacked the Vision first, the two being in a struggle while in midair. Vision blasted Ultron away with a beam of energy from the Mind Stone on his forehead.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 Hulk. With the main Ultron body seemingly defeated, the remaining Ultron Sentries attempted to flee. Under Iron Man's order, Vision joined War Machine in destroying the remaining Ultron drones, using beams of energy from the Mind Stone and ripping apart the drones from the inside to ensure that Ultron could not attempt to download himself in the remaining robots. Watching the Vision's sudden and effective attack in the battle, War Machine was left in a state.

Saving Scarlet Witch
As the Avengers made their way to the Transporters to evacuate, Ultron was able to use one of his final bodies to activate the key and drop Novi Grad out of the sky and tumble towards the ground. As Iron Man and Thor prepared to destroy the city, Vision flew to Wanda Maximoff's aid, as she had stayed behind to torture Ultron's main body. Vision dodged out of the way of the debris and took Maximoff in his arms before flying her out of danger.

Destroying Ultron
"Humans are being fearful and in need of protection. But then, that fear can inspire them to do great things." "You're unbearably naive." "Well, I was born yesterday."

- Vision and Ultron

By the end, Ultron was able to escape with one final drone body. The Vision confronted him and pointed out that he was afraid of death. Ultron mocked him, claiming Tony Stark aimed to create a savior but settled for a slave, to which Vision agreed, noting that they were both disappointments. The 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 agreed that they are, he told Ultron that a thing is not beautiful because it lasts and that he considers it a privilege to be among them. Ultron in responce called Vision unbearably naive, but the Vision simply smiled and countered by saying that he was born yesterday. Ultron attempted to attack, only for Vision to destroy him completely with an energy beam from the Mind Stone, ending the threat of Ultron.

New Avengers
"Avengers A..."

- Captain America

After the battle, the Vision was recruited into the Avengers and travelled 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, as it was blown up by Thor and Iron Man.

Powers

 * Energy Beams: As a result of having the Mind Stone implanted in his forehead, Vision is capable of utilizing its power to fire an intense energy beam from his forehead. This beam is powerful enough to blast away Ultron, and slowly melt away the latter's virtually impenetrable Vibranium shell when aided by Thor's lightning and Iron Man's repulsor beams.
 * Android Body: Designed as Ultron's final form, Vision's humanoid appearance is a testament to Ultron's fascination over evolution and the human form. Vision's base body initially started out as being primarily colored red-violet with sections/patterns colored in a teal-like silver. It is made of both cells and synthetic parts, as well as Vibranium being bonded to its molecules. This makes Vision a perfect splice between organism and machine.
 * Enhanced Durability: Vision's body is composed of Vibranium. This allows him to withstand attacks of immense force with no visible damage to his exterior whatsoever.
 * Synthetic Cell Generation: Vision can willfully generate synthetic material and create clothing or armor made of the material of his own body onto himself in an instant. His initial "naked" appearance was a pure red-violet body with teal metallic patterns. Vision is able to generate armor and a cape similar to Thor's own uniform.
 * Density Manipulation: Vision can instantly increase or decrease his own density, allowing him to becoming hard and durable or completely weightless. This ability gives him an array of superhuman powers including:
 * Enhanced 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. Vision's basic strength is powerful enough to the point that he can evenly match Ultron himself. When wielding Mjølnir, Vision's strength is compounded, allowing him to send Ultron flying away with a single blow.
 * Intangibility: Vision can decrease his density and mass, giving him the ability to phase through 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.
 * Levitation: Vision can minimize his density to its lowest point in order to hover above the ground and fly at fast speeds. He can control his own motion-based force and be able to have complete control of the way he moves, allowing him to instantly stop moving while in the air by completely stopping his kinetic energy and motion.
 * Computer Corruption: Vision was able to hack into Ultron's programming and disable the latter's ability to enter the net. However, the great effort involved in this task temporarily exhausted Vision, keeping him out of the battle 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.
