Quotations
"Of all the creatures in the vastness of the universe, there is none like me. I was present at the birth of the universe, and I shall be there at its end. Though I ravage worlds to live, I bear no malice to any living thing. I simply do what I must to survive. And why must Galactus survive? For, no matter how many worlds I devour... How many civilizations I destroy... It is my destiny to one day give back to the universe — infinitely more than I have ever taken from it. So speaks Galactus." Influence
