The Power Cosmic wrote: The Power Cosmic allows Galactus to produce nearly any effect he desires, including size-alteration, [1] the molecular restructuring and transmutation of matter, [2] the teleportation of objects—even entire galaxies—across space and time,[3] the creation of force fields, [4] the creation of interdimensional portals, [5] telepathy, [6] telekinesis, [7] and cosmic awareness on a universal scale. [8] Galactus has even been shown as capable of creating sentient life,[9] resurrecting the dead, [10] manipulating mortal souls, [11] manipulating the memories and emotions of others, [12] and remaking dead worlds—including their populations—in every detail.
