Known for his distinctive appearance—white skin covered in black, portal-like spots—the Spot's real name is Dr. Jonathan Ohnn, a scientist who gained his powers through a botched experiment involving a portal to another dimension.

The experiment opened a portal to a dimension of space warps, but its instability forced Ohnn to leap inside.

In an interview with Back Issue!, Milgrom discussed the character's creation, "As I recall, the Kingpin wanted to find out how Cloak's power, that would transport himself and Dagger away whenever he chose, worked.

"[2] As a former MIT scientist[3] working for the Kingpin, Dr. Johnathon Ohnn was assigned to reproduce the abilities of the superhero Cloak and created a portal that transported him to another dimension.

[8] The Spot later formed a short-lived team with Gibbon, Grizzly, and Kangaroo called the Spider-Man Revenge Squad, which was better known as the Legion of Losers.

This team fell apart when Spider-Man carted the Spot and the Kangaroo to jail for bank robbery, and Grizzly and Gibbon left the group as they disagreed with their teammates' more ruthless approach.

[9] Some time later, the Spot was captured by an organization called the Gideon Trust and forced to open a portal to the Negative Zone.

Gideon Trust hoped to investigate and exploit the natural resources of the Zone for their own purposes, but were defeated by the Fantastic Four who were trapped there.

[15] Later he begins to kill members of the Russian Mafia in revenge because his son was injured in a drive-by shooting and is now in a coma.

It is later revealed he is serving as a mole for Mister Negative (a fellow Darkforce-powered villain) under the promise that he will be cured once the Maggia crime families are killed.

After Black Cat was thwarted by Spider-Man and Silk, the Spot and the other criminals at the Bar with No Name joined her army when they wanted her to lead them.

[27] The Spot later appeared as a member of the Sinister Six that is led by Aaron Davis in a recolored version of the Iron Spider armor.

[30] During the "Last Remains" arc, the Spot was used by Mayor Wilson Fisk and Norman Osborn to power Project Blank and trap Kindred.

Project Blank was inspired by the Darkforce Dome that was used to surround Manhattan during Hydra's takeover of the United States.

[31] Using his space warps, the Spot can instantly move himself or any part of his body from one area to another over a theoretically unlimited distance via another dimension nicknamed "Spotworld".

His preferred method of attack is to surround his opponent with numerous spots, allowing him to punch or kick them from unexpected angles across great distances.

The same phenomenon was true when Spot flung Spider-Man through a warp and he reappeared in this dimension too close to a wall to dodge.

Due to Spot's connection to "Spotworld", he appears to possess a form of immortality, being able to survive decapitation and reconstitute his body if killed.

[33] Dr. Johnathon Ohnn / The Spot appears in Sony's Spider-Verse trilogy, voiced by Jason Schwartzman.
