Martin Li

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.
