Guardians of the Galaxy #11

The 31st century gets a legendary flame-bearer in Guardians of the Galaxy #11, as a figure clad in a striking black-and-gold Phoenix costume erupts dramatically into the air surrounded by swirling fire — the cover's bold tagline declaring "Even in the 31st Century, There Shall Be a Phoenix" says it all. Below, several heroes — including figures in blue and a flame-powered woman in green — look on amid the fiery chaos, rounding out this "World of Mutants" conclusion. Jim Valentino and Bob Wiacek deliver a cover full of kinetic energy that makes this April 1991 chapter feel genuinely consequential for Marvel's far-future heroes.
