Electro shared an identical history to his counterpart from Earth-120703. Just before his body exploded after being overloaded with energy during his fight against Spider-Man, Dillon was pulled from his timeline and transported through the Multiverse to Earth-199999 due to a botched magic spell cast by that reality's Doctor Strange that was intended to make everybody forget that his world's Peter Parker was Spider-Man. The spell almost caused the infinity of people in the Multiverse that knew Spider-Man's identity to be pulled into the universe, but Strange managed to contain it. Only a handful people from other realities made it to Earth-199999, with Dillon being one of them.
Once arrived to this reality, Electro began consuming electricity from a power line in New York to rematerialize himself. This reality's Spider-Man had become aware that visitors from other realities were running amok, and was instructed by Doctor Strange to restrain them. When Spider-Man arrived at the location where Electro had been spotted, Dillon attacked him. His attacks were blocked by the Sandman, another Multiversal visitor from a timeline variant of Earth-96283. Sandman helped Spider-Man, surrounding Electro with a sandstorm while Peter destroyed the utility poles that were feeding him energy. Dillon was returned to a human form slightly different from his original appearance due to the difference in energy between this universe and his own. Both Electro and the Sandman were subsequently teleported by Spider-Man to Doctor Strange's Sanctum Sanctorum, where he was rounding up all the Multiversal visitors, namely the Green Goblin and Doctor Octopus from timelines variant of Sandman's world, and the Lizard from a variant of Dillon's world.
Strange intended to use the Macchina di Kadavus to send the villains back to their original timelines, but Spider-Man intervened after he realized some of the villains would be put back in a path leading to their death. Against Strange's wishes, Peter incapacitated him and left the Sanctum Sanctorum with the villains, intending to cure them of their plights so they might have a second chance once returned to their timelines. Setting up in the apartment of his friend Happy Hogan, Peter used a device called the Fabricator to create cures for the villains, including a device meant to absorb the excess energy in Dillon's body. Only Doctor Octopus was cured and freed from villainy when Norman Osborn was taken over by his Green Goblin persona and coaxed the other villains to reject Peter's cures. Dillon wanted to stay in this new universe, believing that he could be more than what he was back home. After stealing an arc reactor from the Fabricator to enhance his powers, Electro blasted Octavius off the building and fled.
Peter would then join forces with the Spider-Man of Earth-96283 and the Spider-Man of Earth-120703, who had also been brought into his world by Strange's botched spell. After developing new cures for the villains, they lured them to the Statue of Liberty, using the Macchina di Kadavus as a bait. Electro, the Lizard and the Sandman arrived first and confronted the three Spider-Men. Doctor Octopus arrived at the battle, tricking Dillon into thinking he was in the villains' side by attacking two of the Spider-Men who were at Dillon's mercy. Octavius caught Electro off guard and used his mechanical arms to strip the arc reactor off Dillon attach the energy siphon on him, reverting him to normal. Earth-120703's Peter met the depowered Max, convincing him that despite the fact he had lost his power, he was never a nobody. Max jokingly expressed disappointment that Spider-Man was not black, but acknowledged that he was a good kid trying to help those who needed it. Following the arrival of Doctor Strange to the battle and the destruction of the Macchina di Kadavus at the hands of the Green Goblin, the fabric of reality began to tear apart. Spider-Man asked Strange to cast a new spell to make the entire world forget Peter Parker's existence, which negated the initial spell and undid its effects. Dillon and all the other visitors from the Multiverse returned to their homes as a result.
Max apparently no longer possesses any power after most of the electricity was removed from his body.
- Gifted Intelligence: Max possessed knowledge about electrical energy and devices, although he had a weak mind due to the fact that he considered himself a "nobody".
- Expert Engineer: Max was an electrical engineer and designed Oscorp's electrical network
- Jamie Foxx portrays Electro in the film Spider-Man: No Way Home, reprising his role from 2014's The Amazing Spider-Man 2.
- Due to the established rules in the Marvel Multiverse pertaining to alternate realities and time travel, which also apply in the Marvel Cinematic Universe as per Avengers: Endgame, it is assumed that this version of Electro can't be the exact same one from the 2014 film. This is because his depowerment and return to his original timeline would have to create a divergence from Earth-120703.
- This version of Electro was based on the main comic counterpart (Earth-616), as he use the advanced electricity grids of Earth-199999 and the Arc Reactor propel him to a new design that resembles his classic comic book look: yellow electricity and his trademark mask, represented by flashing sparkles on his face.
- Max hates the woods.
- When first seeing Earth-120703's Spider-Man unmasked, Electro jokingly expresses disappointment that his universe's Peter Parker was not a black person, and hopes that a "Black Spider-Man" exists somewhere in the Multiverse. This is presumably a reference to the existence of Miles Morales.
