Martin Li

A Chinese immigrant who secretly harbors a sinister alternate persona called Mister Negative, Martin Li presents himself as a benevolent New York philanthropist and founder of the F.E.A.S.T. shelter network while covertly commanding the Inner Demons crime syndicate, wielding a dual light-and-dark energy that can corrupt or heal anyone he touches.

Few Modern Age Marvel characters arrived with as much quiet intrigue as Martin Li, who made his debut in the landmark Free Comic Book Day 2007 (Spider-Man) #1, brought to life by the celebrated team of Dan Slott and Phil Jimenez. Over nearly two decades — 107 catalog appearances and counting — he's carved out a genuinely compelling corner of the Spider-Man universe, turning up most frequently in the pages of The Amazing Spider-Man and Ultimate Spider-Man alongside heavy hitters like Mister Negative, Kingpin, Hammerhead, and Aunt May Parker. Three of his appearances carry key-issue weight with collectors, a testament to how much story weight this character has accumulated since that splashy Free Comic Book Day introduction. If you're diving deep into Modern Age Marvel street-level drama, Martin Li is a name you'll keep encountering — and one absolutely worth following.
