Wolverine Vol.1 #137-138
Galactus's real name is Galan. Galactus possesses cosmic power beyond the abilities of human beings to measure. Galactus is able to use the vast energies within him for an incalculable number of effects. Some of his most rudimentary abilities are the molecular restructuring or conversion of matter, the projection of energy with enormous concussive force, the teleportation of objects across space or even time, and the erection of invincible energy-screens and force fields. Even his heralds, whom he has endowed with a small fraction of his ever-renewing power, are able to manipulate matter and energy in ways far beyond human comprehension.
