Guardians of the Galaxy #21

Set in the 31st-century Marvel Universe, this February 1992 issue announces its central threat right on the cover — "Rancor Is Back!" — as the feral, clawed villain tears into a chaotic brawl alongside her white-haired lieutenants against multiple Guardians, including a shield-wielding warrior in red, white, and blue and a compact armored figure with a heavy weapon. Jim Valentino and Dan Panosian pack the cover with kinetic energy, filling every corner with combatants mid-leap and mid-strike. It's a genuinely crowded, high-stakes clash that makes a strong case for picking up this chapter of the Guardians' ongoing 31st-century saga.
