Galactus

Galactus is a cosmic entity known for consuming the energy of entire planets to sustain himself. Originating as Galan from the universe before the Big Bang, he transformed into a being of immense power and cosmic significance. He commands the Power Cosmic and often employs Heralds to seek worlds for him to feed upon. Galactus embodies the cycle of destruction and creation on a universal scale, existing beyond typical mortal constraints.
