M.O.D.O.C.

Few villains in the Modern Age arrive with quite the gleeful menace of M.O.D.O.C., who burst onto the scene in 2007's Marvel Adventures The Avengers #3, conjured by the sharp imagination of Cameron Stewart. Over a run stretching from 2007 to 2023, this Marvel creation has haunted titles like Captain America: Sentinel of Liberty and Marvel Universe Avengers: Earth's Mightiest Heroes, sharing pages with the likes of Steve Rogers, Nick Fury Jr., and George Tarleton. With only nine catalog appearances, M.O.D.O.C. is a rare, choice find — the kind of deep-cut antagonist that rewards the curious collector willing to dig past the household names.
