When Marvel Comics writers need a powerful character to clean up, they usually insert Galactus into the plot, one way or another, and it does. Here we are, this is the power level of madness. At the same time, his nickname is the Destroyer of planets, so we’re going on very, very heavy. The guy, considered a living God, even allows himself to be an occasional member of the Cosmic Tribunal. And where it’s really strong is that no one can say what it looks like! It is simple, every conscious being perceives it in a form peculiar to its beliefs, so it changes all the time of appearance, impossible to know the true.
His powers have no limit, he is capable of creating life, like sowing death, at his pleasure. Clear the guy is more of a force of nature than a simple superhero, he sets the bar high and the day the MCU will want a villain (or a nice guy according to his mood) really almost unbeatable, the House of Ideas will do land Galactus!
