Many casual fans had their introduction to Galactus in the latest Fantastic Four. However, the character is not new. Galactus is an ancient being who existed in the universe prior to this one. Moments before the Big Bang of the current Marvel Universe, he was shunted into it. Formerly known as Galan, Galactus, the Devourer of Worlds, is now a cosmic force of nature who literally eats planets.
He is now a creature of celestial hunger that needs to consume planets to survive. No one knows what he truly looks like. The citizens of different planets see him in a different way. He chooses a planet, sets up a city-sized device, and strips the energy from the planet to feed himself.
