The Spot

Jonathan Ohnn, better known as the Spot.

He is a scientist from Alchemax who managed to transport a radioactive spider from Earth-42 into Earth-1610, causing it to bite Miles Morales and turn him into Spider-Man. During the destruction of Kingpin's Super-Collider, Jonathan was accidentally mutated by a batch of dark matter he was carrying, transforming him into a dimension-travelling supervillain that poses a threat to the entire multiverse.

Personality: At first, Spot appears as a goofy and incompetent man who, in spite of committing crimes, was pretty friendly towards those around him and often tried to avoid harming bystanders in the way. Because he believes himself to be responsible for giving Miles Morales' his powers, he feels very entitled about it and expects to be given respect for it. He has also declared himself to be Miles' arch-nemesis, something that Miles himself didn't initially see him as.

However, over the course of events, he slowly began to show a sinister and power-hungry side of himself, wanting to obtain full power, even at the cost of countless lives. Spot's motive boils down to his envious hatred towards Miles Morales, blaming him for turning him into a mutant and actively seeks to one day kill him himself.

For this very reason, Spot is determined to make Miles suffer in every way that he is more than willing to hurt and kill his close loved ones, including his father, Jefferson. He also intends to put other lives at great harm, regardless of whether they oppose him or not.

History: Prior to his official introduction, Spot was a scientist at Alchemax named Jonathan Ohnn, and was one of the many that worked with Kingpin on the Super-Collider project, under Olivia Octavius' supervision. He primarily used the Super-Collider to conduct experiments, but one of them involving a spider caused an alternate version from Earth-42 to replace it, which then led the spider to biting Miles, granting him his powers. He was later seen during Miles and Peter's escape from Alchemax, where he was hit in the head with a bagel.

After the Spider-Men destroyed the Super-Collider, Jonathan had mutated from the explosion, causing his skin to turn pure white, his face disappearing, and portals of the dark matter absorbed, appearing all over his body. Due to his unnatural appearance causing him to be rejected by his friends and family, and the company he worked at being shut down, Spot decided to use his new abilities to steal money and survive.

Spot attempts to rob an ATM at a local bodega, causing him to be attacked by the cashier, who he manages to defeat. Miles then arrives and gets in a fight with Spot, who proclaims himself Miles's nemesis, becoming infuriated when Miles relegates him to a villain of the week. Eventually returning to the remnants of the Super-Collider, Spot reveals his origins to Miles, who remains nonchalant towards their mutual relationship. Angered at this, Spot attempts to attack both Miles and Jefferson, spawning multiple holes around him, before accidentally falling into one of his holes, resulting in kicking himself into the Spot Dimension. Upon entering it, he loses all of the holes covering his body but ends up traveling to alternate universes surrounding him. Accidentally returning to his own universe, Spot realises the power his holes can grant him, and ventures to take revenge on Spider-Man.

Gathering materials and returning to his workshop apartment, Spot creates a miniature Super Collider, creating more holes which attach to his body, before finally sending him to another universe. Gradually become more empowered by harvesting the dark matter of other universes' Super Colliders, Spot eventually arrives at the city of Mumbattan (a hybrid of Mumbai and Manhattan) on Earth-50101 where he is confronted by Miles, Spider-Gwen, Spider-Man India and Spider-Punk who have been tailing him. After a lengthy chase through the city, Spot reaches and activates the Alchemax Super Collider, despite the Spider-Mens attempts to stop him.

Embracing the dark energy of the Super Collider, Spot intentionally or unintentionally shows Miles a vision of his impending destruction of their mutual universe. Finally becoming a more unstable and dangerous entity, Spot swears he shall take everything away from Miles as Miles had done to him, before teleporting away, causing the area to collapse and forcing the rest of the Spider-Men to evacuate.

It is later revealed that part of Spot's plan involves the death of Miles' father, Jefferson, which is his canon event, leading to Miles escaping back his own earth in order to go back after Spot. However, he instead ends up landing on Earth-42 where he was captured, while Spot manages to arrive back at Miles' world, with the intent of resuming his plans.
