A character is Marvel comics that wields the Power Cosmic, oft said to be the most powerful being in the Marvel Universe. He spends his time using his God-like powers to devour planets in order to feed his massive body and the energy it requires. Standing from 50-1000 feet tall depending on differing accounts, and weighing in at 250 tons, Galactus is considered nearly invincible due to his god like powers.
