Mister Negative

Mr. Negative is a Marvel Comics supervillain and an enemy of Spider-Man. Created by Dan Slott, he first appeared in the 2007 Free Comic Book Day issue, Amazing Spider-Man: Swing Shift, and later made his first appearance in an ongoing mainstream Spider-Man title in Amazing Spider-Man #546 (January 2008).

Not much has been revealed yet about Mr. Negative. What is known is that he is Martin Li, a Chinatown crime boss beginning to make his first power play toward taking control of New York's criminal underworld. To accomplish this, he hires Overdrive as a courier to deliver a stolen Lemurian tablet, the Tablet of Death & Entropy, which contains a formula for a poison, the Devil's Breath. The crime boss intends to use this poison to gas, and effectively wipe out, all existing members of the Karnelli and Maggia crime families. He demonstrates a twisted sense of honor after slaying his own henchmen for not rewarding a crooked detective with a share of their profits, when the detective brings Mr. Negative the tablet he had requested. He also shows he can be quite cunning and forward-thinking, as he has taken the time to copy down the text on the tablet before Spidey smashes it.

Mr. Negative appears to possess superpowers of some kind, as he charges up a knife with black electrical energy and later transforms into his civilian identity in the same manner. During their most recent encounter, Spidey notes that Mr. Negative possesses some degree of superhuman strength after he hurls a mafia boss's child into a river.

As Martin Li, Mr. Negative is a philanthropist who runs a soup kitchen in Chinatown, the F.E.A.S.T. Project, where Peter Parker's Aunt May volunteers. Neither Peter nor May is aware of Li's dual identity.

Mr. Negative is slated to return soon in future issues of Amazing Spider-Man.
