Galactus (theoretical concept)

Galactus is a fictional character from Marvel Comics, often referred to as the "Devourer of Worlds." He is depicted as a cosmic being who requires immense amounts of energy to survive, which he derives from consuming entire planets. Galactus represents the vast and often indifferent forces of the universe, embodying themes of power, existence, and the balance of nature. His presence in stories often raises moral questions about survival, sacrifice, and the consequences of an entity that operates on a scale beyond human understanding. Galactus is a complex symbol of both creation and destruction in the universe.
