Adventures of Superman #477

Phase Four of the "Time and Time Again" crossover arrives in this April 1991 issue, pitting Superman against the Sun-Eater alongside the Legion of Super-Heroes. Dan Jurgens and Brett Breeding's cover — inked by Art Thibert — is a vibrant burst of cosmic energy, with Superman at the center clutching what appears to be the Earth itself, flanked by Legion members including a lightning-fast speedster, a small atomic-powered hero radiating a starburst, and an armored Legionnaire charging into the fray. It's a genuinely thrilling team-up image that captures the grand, galaxy-spanning stakes of one of 1991's most ambitious Superman storylines.
