Galactus, known as the Devourer of Worlds, is one of Marvel’s most powerful cosmic entities. Once a mortal named Galan, he transformed into a colossal being who sustains himself by consuming the energy of planets. Towering and enigmatic, Galactus is both a destroyer and a force of balance in the Marvel Universe, often accompanied by his heralds, such as the Silver Surfer. © 2025 MARVEL
