Super Skrull

A cunning alien warrior born in the Silver Age, Super Skrull has been a fixture of Marvel's cosmic landscape since debuting in 1968's Captain Marvel #2, and has gone on to haunt the pages of Fantastic Four and even the grim corners of Marvel Zombies across an impressive 57-year run. Few characters embody Marvel's interstellar ambitions quite like this shape-shifting schemer, who shares adventures with heavy hitters including Victor Von Doom, Ben Grimm, and the fiery Johnny Storm — company that speaks volumes about the high-stakes worlds he inhabits. Whether you're a cosmic Marvel devotee or a Fantastic Four completist, Super Skrull is one of those enduring Silver Age creations whose longevity alone tells you everything about his staying power.
