Mister Negative

Mister Negative is a supervillain appearing in American comic books published by Marvel Comics. The character is usually depicted as an enemy of Spider-Man, the Punisher, Shang-Chi, and Cloak and Dagger. The character was created by Dan Slott and Phil Jimenez, and first appeared in "Swing Shift", a story in Free Comic Book Day: The Amazing Spider-Man #1 (May 2007). The name "Mister Negative" is a reference to photographic negative, as the colors of his skin, hair, and costume are inverted when he transforms into his alter ego.

Originally a gangster and human trafficker whose real name was never revealed, the man who would become Mister Negative was captured by crime boss Silvermane to serve as a test subject alongside the future Cloak & Dagger for an experimental procedure involving a synthetic drug created by Simon Marshall. The experiment gave the character control over both the Darkforce and Lightforce, and led to the creation of two personalities: Mister Positive, posing as a benevolent and kind philanthropist named Martin Li, who would go on to found the F.E.A.S.T. Project as a means to help homeless people; and the ruthless crime lord Mister Negative, who leads the Inner Demons crime gang in an attempt to take over New York’s criminal underworld. Originally, the character was depicted as suffering from dissociative identity disorder, with one personality not maintaining the other's memories, but both were later shown to be fully aware of the other's existence. As Mister Negative, his powers include healing, mind-control through "corruption", and charging weapons with his energy.

Since his conception, Mister Negative has been adapted into several forms of media outside of comics. Keone Young and Eric Bauza voice him in the animated series Ultimate Spider-Man and Spider-Man (2017) respectively, while Stephen Oyoung voices the character in the 2018 Spider-Man video game. In 2025, he appeared in the second season of Moon Girl and Devil Dinosaur where he was voiced by Bowen Yang.
