Mysterio

Beck arrives at Nick Fury's Berlin base to ambush Spider-Man, disguised as Fury himself. When they arrive, Mysterio first stuns Fury and then creates various illusions that frighten Parker, who doesn't know what to do with them. In one illusion, he grabs Michelle Jones by the neck and throws her down, with Spider-Man chasing after her. Mysterio then distracts Parker by appearing as an illusion, and Parker attempts to stun him but instead hits a building, severely injuring his hand. Using more Stark Industries combat drones, Mysterio creates even more illusions, even creating an illusion of his tech suit and homemade suit. The Mysterio illusion flies to Fury, and Beck says he's searched the entire bridge but found nothing. However, Maria Hill didn't find an energy surge in the middle of the bridge. Mysterio flies off to take another look, saying this shouldn't be happening and that only Gom can help them all. Once the call ended, Beck contacted William Ginter Riva and informed him that the Combined Elemental was an "Avengers-level threat." Beck then ordered Riva to deploy drones from Stark's satellite. Realizing that Spider-Man could thwart their plans to destroy London, Beck tells Riva he will kill Parker. In the illusion, Parker, who has penetrated the illusion, destroys numerous drones with his synthetic webbing and later finds the Elemental's weakness, finally disabling the Elemental's illusion and creating the illusion that he is Tony Stark.

While the team was already utilizing the new technology, Peter Parker and Jones examined the projector and realized that the entire battle had been an illusion. Meanwhile, Beck's team prepared for the next attack, which would take place in London, England. At their base, Beck and his team were testing William Ginter Riva's new Stark Industries combat drones in action. He tested an illusion of Mysterio fighting a combined elemental.

Beck then tells Riva to rewind the illusion to the very end. When the rewind occurred, Beck said the performance was rather weak, but it would do. Next, Beck told Riva to remove the illusion and activate the drones in combat mode. Riva activated combat mode, and the drones began firing at the entire base. Although Riva was pleased, Beck believed the damage was weak enough, so he told Riva to double the drones' destruction and start over. William activated the illusion, which was twice as fast as the previous one, and Beck was satisfied with the illusion and the tests. Beck said that London is a beautiful city, and even though it will suffer at his hands, it will still be rebuilt. And if he is the new Iron Man, he must save the whole world from cosmic threats. He activates the illusion of Mysterio's suit and enters it, thereby "putting it on." Calling himself a savior, he says people will forget their losses when they remember they have Mysterio. Beck asks Janice Lincoln if there's a replacement Mysterio suit, and she replies he can try it on already. When Beck refuses and shakes his hand, he sees that the illusion isn't aligning with him, creating glitches. Riva says that one of the drones returned damaged during the battle in Prague without its projector, thinking it was no big deal. Beck says he only just learned about this. Riva tries to reassure him that the image won't be affected by just one projector, but Beck tells him they could be discovered. Beck uses E.D.I.T.H. to locate the part and learns that Parker has it. Beck gets angry and accuses Riva of being responsible.

Before the attack, Beck observes Peter Parker while he is on a trip to Europe with the Midtown School of Science and Technology. After spying on Parker, Beck unleashes a water elemental on Venice, which wreaks havoc throughout the city, frightening everyone. As the elemental attacks the city, destroying buildings and vehicles, Peter Parker attempts to defeat it, but is unsuccessful. Then, an illusion of Mysterio flies to Parker's aid on his green cloud, activating his shields to defeat the enemy. As the elemental begins to attack him, Mysterio uses his green energy to deflect the water elemental's blows. He then creates a shield to block the elemental's blow, but the elemental manages to knock Beck's defenses away, stunning him. But Mysterio refuses to give up, emerging from the water and again attempting to defeat his opponent with his magic. He is then approached by Parker, who had tried to help him. Mysterio then tells Parker they need to lead the Elemental away from the waterways and continues the battle. After the Elemental interrupts Parker and Beck's conversation, Mysterio decides to lead it away from the waterways himself, leading the Elemental to chase Mysterio across Venice. During this chase, Mysterio attempts to damage the Elemental, though he is unsuccessful. During the battle, the Elemental attempts to destroy a tower. Parker attempts to secure the bell tower, which is about to collapse, but Parker manages to hold it back. When Beck is stunned by the Elemental, Mysterio creates a cloud for himself and then uses green magic to restrain the Elemental by its neck. However, the Elemental manages to free itself from its trap. Then Mysterio decides to use the same magic to restrain his hands, and he manages to defeat the water elemental and suddenly destroy it, ending the whole spectacle with his victory, convincing Parker that he is a hero. By that time, Beck still had no idea that one of the illusion projectors had been stolen by Michelle Jones during the battle in Prague.

Using his powers of deception and illusion, Beck decides to create a persona for himself as a model superhero, battling creatures known as the Elementals. He also assembled his own team, consisting of former Stark Industries employees who shared a similar motivation for hating Tony Stark: William Ginter Reeve, Victoria Snow, Guts Guterman, Janice Lincoln, and Dawg. With Guterman's help, Beck concocts a backstory: he is a superhero from Earth-833 who, along with his battalion, fought against the Elementals and, along with them, is transported to the real Earth after the Snap, having lost his home Earth and his wife.
Additionally, Beck, along with Lincoln, developed a suit that made him appear to be in control of his powers. With Lincoln's help, Beck also discovers that Peter Parker has access to special Stark sunglasses, which grant him access to Stark Industries' combat drones, which Beck intends to seize. Mysterio sent an Earth Elemental to Ixtenco, Mexico, to gain the approval of Nick Fury and Maria Hill. When Nick Fury and Maria Hill arrive to clean up the aftermath of a hurricane, Quentin Beck arrives and asks them who they are. Mysterio attacks Sandman. The Earth Elemental then appears, and Mysterio tells them to stand back and directs green energy at it. Using his magical abilities against it, Mysterio manages to defeat the Earth Elemental. After his victory, Beck wins the approval of Nick Fury and Maria Hill and tells them the story of the Elementals. Some time later, Mysterio unleashed the air elemental on Morocco and "defeated" it. After the battle in Morocco, Beck and his team prepared for their next attack. Later, Beck sent the water elemental to Venice, Italy.

He enjoys committing evil for pleasure and achieving his goals. He has a healthy dose of sadism and opportunism. He almost never helps anyone unless he sees a benefit. Mysterio enjoys killing, he enjoys hiding forever, and he enjoys being dark and mysterious. There's so much romance in it. It's important to remember one crucial condition: his evil must go unpunished. For this reason, he prefers to engage in shady deeds when no one is watching and avoids legal trouble.

His desire for beautiful effects and exits is so great that his crimes are always connected with a large number of himself

Having proven himself a skilled designer and inventor, Quentin Beck was hired by Stark Industries, where he began working as an engineer for Tony Stark. In 2012, Beck specialized in developing holographic technology and created a holographic emitter capable of creating realistic illusions, which Stark dubbed the "Mental Organic Retro-Gram," or M.O.R.G. Beck then filed a patent for his holographic invention, but it was unsuccessful. Stark filed the patent for M.O.R.G. himself, though he removed Beck's name and listed himself as the inventor. During his work, Beck actively participated in the creation of a prototype illusion technology, believing it would change the world. Beck's technology caught Stark's interest, even though Stark himself believed he was mentally unstable despite his great inventions. However, Beck felt unacknowledged as an inventor by Tony Stark, as he wanted to use his technology to create illusions for the world. Stark rejected his idea for illusion technology and renamed it the Mental Organic Retro-Gram, or M.O.R.G., which was intended to treat mental trauma, something Beck was very unhappy about. In 2016, Stark used M.O.R.G. to portray his last meeting with his parents before their death at MIT. Beck was backstage at the time and was dissatisfied with the performance, as Stark never once mentioned him as a co-creator. Then, due to the callousness Beck acquired due to his need for attention, Stark decided to dismiss him as mentally unstable, which has led Beck to harbor a lifelong grudge against him. In 2023, Tony Stark dies during the Battle of Earth when he used the Infinity Stones to vaporize Thanos and his entire army, though Stark himself dies from massive gamma radiation exposure. Angry at Stark, Beck seizes the opportunity to become the next world-famous superhero, as the "New Iron Man."
