Mister Negative

A crime lord with two opposite personalities, one benevolent and one ruthless.

Mister Negative is a Marvel Comics supervillain who frequently opposes Spider-Man, the Punisher, Shang-Chi, and Cloak and Dagger. Dan Slott and Phil Jimenez created him, and his debut came in the story "Swing Shift" within Free Comic Book Day: The Amazing Spider-Man #1 (May 2007). His alias draws from photographic negatives, since his skin, hair, and costume colors reverse when he shifts to his criminal identity.

Originally an unnamed gangster and human trafficker, the man who would become Mister Negative was taken by crime boss Silvermane to be a test subject for an experimental synthetic drug developed by Simon Marshall. That procedure granted him mastery over both the Darkforce and Lightforce, splitting him into two opposing personalities. One is Mister Positive, a generous philanthropist named Martin Li who runs the F.E.A.S.T. Project to aid the homeless. The other is Mister Negative, a ruthless crime lord leading the Inner Demons gang in a bid to dominate New York's underworld. Early stories portrayed him with dissociative identity disorder, where neither personality could access the other's memories, though later tales showed both fully aware of each other. As Mister Negative, his abilities include healing, mind control through "corruption," and charging weapons with his energy.

Outside comics, the character has appeared in several adaptations. Keone Young voiced him in Ultimate Spider-Man, Eric Bauza in the 2017 Spider-Man series, and Stephen Oyoung in the Marvel's Spider-Man video games. In 2025, Bowen Yang voiced him in the second season of Moon Girl and Devil Dinosaur.

Publication history Dan Slott and Phil Jimenez introduced Mister Negative in Free Comic Book Day: The Amazing Spider-Man #1 (2007), set after the "Spider-Man: One More Day" storyline. He next appeared in The Amazing Spider-Man #546 (January 2008), the first issue of the "Spider-Man: Brand New Day" arc.

Fictional character biography Martin Li's public backstory claims he was a Chinese immigrant from Fujian who tried to reach America to reunite with his wife. He supposedly traveled on the Golden Mountain, a slave ship run by the Snakehead gang that sold Fujian captives into overseas slavery in Kenya. During a storm, the crew abandoned ship, leaving the captives to swim for New York's shores.

Lore & Background

Originally a gangster and human trafficker whose real name was never revealed, the man who later becomes Mister Negative was captured by crime boss Silvermane to serve as a test subject for an experimental procedure involving a synthetic drug created by Simon Marshall. The experiment gave him control over both the Darkforce and Lightforce and led to two opposite personalities: Mister Positive, posing as a philanthropist named Martin Li who founded the F.E.A.S.T. Project to help homeless people, and the ruthless crime lord Mister Negative, who leads the Inner Demons gang. Originally depicted with dissociative identity disorder where neither personality could access the other's memories, both were later shown to be fully aware of the other's existence.

Martin Li is introduced with the backstory of a Chinese immigrant from Fujian who attempted to travel to America to be with his wife aboard the slave ship Golden Mountain, operated by the Snakehead gang. During a storm, the crew evacuated, leaving captives to make for New York shores; Li was the only survivor and built a fortune helping others. This story is later revealed to be partially false—only the Mister Negative persona appears aware that Negative was actually a crew member who stole the identity of a deceased Fujian slave. He was later captured by Silvermane, experimented on, and escaped, developing two personalities. The Mister Negative side dedicated himself to becoming Chinatown's Kingpin of Crime while Martin Li ran the F.E.A.S.T. center.

Mister Negative first clashed with Spider-Man during the "Brand New Day" storyline, attempting to take over New York's criminal underworld by wiping out Maggia and Karnelli crime families with a bioweapon called Devil's Breath. He later encountered Eddie Brock, curing Brock's cancer with a touch, which combined with remnants of the Venom symbiote to create Anti-Venom. Negative refused to submit to Hood's rule, leading to conflict, and was publicly outed as Martin Li by the Wraith using visual recognition software. During "Spider-Island", he was told of a prophecy that he would be killed by Dagger, leading him to kidnap Cloak and Dagger and alter their powers.

Reader's Guide

Mister Negative's significance lies in his dual identity as both a benevolent philanthropist and a ruthless crime lord, embodying the theme of hidden darkness within apparent goodness. His creation during the "Brand New Day" era of Spider-Man comics introduced a complex antagonist whose powers of corruption and healing made him a unique threat. The character's backstory as a former human trafficker who stole another man's identity adds layers of moral ambiguity, as his Martin Li persona is built on a lie. His influence extends beyond comics into animated series and video games, notably the Marvel's Spider-Man video game series where he serves as a major antagonist. The F.E.A.S.T. Project, which he founded, became a recurring element in Spider-Man lore, providing a setting for Aunt May's volunteer work and later conflicts. Mister Negative's ability to corrupt others and create Anti-Venom had lasting repercussions in the Marvel Universe, and his rivalry with Spider-Man, Cloak and Dagger, and the Hood solidified his place as a notable villain in New York's criminal underworld.
