Fictional character biography
Martin Li is a seemingly good willed philanthropist who runs a soup kitchen in Chinatown, the F.E.A.S.T. Project (Food, Emergency Aid, Shelter and Training), where (Spider-Man) Peter Parker's Aunt May volunteers. Neither Peter nor May are aware of Li's dual identity as a Chinatown crime boss under the name Mister Negative.

During the first story of the Brand New Day, Mister Negative first comes into conflict with Spider-Man when he makes a power play toward taking control of New York's criminal underworld by attempting to wipe out all existing members of a Karnelli and Maggia crime families using a DNA specific bioweapon called the "Devil's Breath".

Powers and abilities
As Mister Negative, Li's appearance resembles that of a photographic negative. He also speaks in a reverse colored text bubble.

Mr. Negative charges up a knife with black electrical energy and transforms into his civilian identity in the same manner. During an encounter in Amazing Spider-Man #548, Spider-Man notes that Mr. Negative possesses some degree of superhuman strength.

Mr. Negative is often accompanied by several henchmen, known as his Inner Demons, who wear Dragon style masks and use high tech electric emitting versions of Japanese weapons including the Bō and Nunchaku.
