Galactus is the physical, metamorphosed embodiment of a cosmos and maintains his existence by devouring planets that have the potential for supporting life. This has resulted in the elimination of entire extraterrestrial civilizations on numerous worlds. Galactus wields the Power Cosmic and can employ it to produce nearly any effect he desires, including the molecular restructuring and transmutation of matter, the teleportation of objects — even an entire galaxy — across space or time, size-alteration, the projection of energy with indeterminable destructive force, the erection of nearly impenetrable force fields, the creation of interdimensional and intra-dimensional portals, telepathy, telekinesis, pyrokinesis, and a form of cosmic awareness. Galactus is also capable of creating sentient life, resurrecting the dead, manipulating mortal souls, memories, and emotions, and restoring dead planets and populations in every detail.

Also, he loves you. <3
