The Battle of London was the final confrontation between Spider-Man and Mysterio, and the final Elemental Attack. This conflict signified the appearance of the Elemental Fusion, an amalgamation of the four Elementals, representing the elements of Air, Earth, Fire, and Water.
Fresh from escaping confinement in a Netherlands jail, with aid by Happy Hogan for a pick-up, Spider-Man arrived and managed to destroy the Elemental illusion terrorizing London. From then on, Spider-Man battled Mysterio's swarm of Stark Industries Combat Drones, before confronting him in the Tower Bridge observation walkway.
After Mysterio accidentally got caught in the crossfire of one of his attack drones, Spider-Man reclaimed the E.D.I.T.H. glasses in his possession to call off the attack, saving the city. With his last breath, Mysterio proclaimed people will believe anything, where later upon Spider-Man's return to New York City and saw the news broadcast of his identity being exposed.
After Spider-Man discovered Quentin Beck's deception to make 'Mysterio' a great hero by staging crises to then save people, he tried to warn Nick Fury in Berlin. However, Beck intercepted him and tricked him into revealing who else could know his secret. Beck used illusions to chip away at Parker, tripping him into the path of a train. Believing Parker to be dead, Beck went on his way to London to stage an Elemental attack to cover his killing Parker's friends.
Meanwhile, Parker survived the train collision, and after waking up in the Netherlands, he called Happy Hogan for aid. Hogan arrived with the Stark Industries Private Jet, and provided first aid. Knowing that Beck planned to cover his tracks by killing his classmates, Hogan gave Parker a passionate speech and access to the Quinjet's Suit Synthesizer to make a new suit. Parker, not aware of where his class would be at the moment, had help from Hogan and found his friends by way of Flash Thompson's live stream, and they plotted a course for London. Parker planned on how to defeat Beck as he built his new suit.
Quentin Beck deployed his team to intercept and trap Parker's class on Tower Bridge, and began his illusion of the Tempest Elemental over them. Beck tried to tell a narrative of what the monster is and how it might have came to be, but 'Nick Fury' and 'Maria Hill' didn't buy it. En route, Happy Hogan relayed a covert message to 'Fury' while also locating Parker's friends. As the illusion began, the class evacuated the bus and witnessed Mysterio fighting the monster. Michelle Jones and Ned Leeds, realizing Beck could be aware they knew the truth, branch off from the group to find cover and remove casualties. However, Flash Thompson and Betty Brant soon followed upon noticing their departure.
Arriving in London, Spider-Man dive bombed from the jet in his new suit, gliding his way into the illusion. There, he created a linkage of taser webbing which shorted out the drones, destroying the illusion. Examining through a drone's live feed, an enraged Beck contemplated how to spin the situation. He cuts the illusion and has the drone fleet attack Spider-Man on Tower Bridge. With his upgraded suit, Spider-Man handled the drones and confined them to the bridge, but their density around Beck provided him with impeccable defense, forcing Parker to fight the whole swarm until an opening could form.
As 'Fury' watched on from the office, a cloaked drone Beck had readied to kill them revealed itself, while a ready 'Hill' already on the roof had fired a rocket launcher to destroy it. Their suspicions of Beck's deceptions were officially confirmed. While running away, Jones, Leeds, Thompson, and Brant encountered Hogan, who landed the jet to attempt to rescue them. However, the drones destroyed the jet, forcing them to make their way to the vault of the Royal Crown Jewels. Having narrowly escaped, they locked themselves in the vault, but the drones slowly began cutting through the doors.
As they awaited the drone invasion, each confessed a regret in life: Leeds regretted wasting so much time on video games, Brant regretted not using her fake ID after the Blip since she is "technically" twenty-one, Jones confessed her over-honesty was to cover her awkwardness, and Thompson confessed to not even liking his own live stream. Hogan, however, reminded Thompson that his streams allowed Spider-Man to find and save them, giving Thompson joy to know his favorite hero follows him. As the last of them, Hogan confesses to being in love with "Spider-Man's aunt" to which they all turn to him with intrigue, as he thought they were openly sharing.
Following a prolonged skirmish with the drone fleet, Spider-Man ran out of web fluid and grew fatigued. But upon sighting a downed drone, Spider-man threw a toy at its sonic cannon, which projected the toy into the air and the drones overhead attacked it. Based on this, Spider-Man then devised a plan: by using the stripped off sonic cannon, paired with the broken off sign to Tower Bridge, Spider-Man broke through the drone fleet by having them destroyed from shooting the sonic cannon, which broke a hole in the defenses large enough to make it to Beck. Spider-Man apprehended Beck, and broke his interface dome helmet which disengaged the remaining drones. This occurred just in time, as the drones piercing the Vault deactivate upon reaching Hogan and Parker's friends.
Atop Tower Bridge's upper walkway, Parker has Beck in his hands until Beck calls on E.D.I.T.H. to summon drones to attack Parker. As he narrowly dodges the drones, Parker ends up at the opposite end of the walkway from Beck, who taunts the young hero to take the glasses from him. Beck activates the illusion projectors which create a virtual void of darkness. Parker, however, calms himself, closes his eyes, and relies on his hyper-awareness ability; adopting the "Peter Tingle" moniker May gave it.
Parker rushed into the walkway blind, but fully aware of the drones hidden by illusion holograms and proceeded to destroy them, ending the darkness illusion and closing the distance between him and Beck. However, in raging desperation, Beck commanded E.D.I.T.H. to order his orbiting defense drones to fire on Parker, which failed as the young hero used one drone as a shield to break another drone, and the second to last drone to fall misfired and hit Beck in the abdomen.
Once Parker destroyed the last drone in the walkway, he stood over Beck and heard his motivations. But as Beck gestured the glasses to Parker, his "Peter Tingle" warned him of the real Beck cloaked beside him with a gun to his head, and counters immediately. Beck's shot missed Parker's head and broke the window adjacent to him. As Beck dropped to the floor, Parker took the glasses to force a recall command execution.
Upon the exodus of the drone fleet, Beck gasped his last words to Parker of how everyone will believe anything. With Beck seemingly dead, Parker asks to confirm if Beck is truly dead, with E.D.I.T.H. confirming there are no illusions in play. Parker then exits Tower Bridge.
