The Avengers will face their strongest enemy yet

Back in Infinity War, every one of us thought that it is the end for earth's mightiest heroes. Thanos was too much for the Avengers to handle. And in the end, he was able to fulfill his destiny. With just a snap (literally), half of the world's population vanished into a place unknown. And he said that he did it for "salvation." But what if we tell you that the Mad Titan is right? A theory suggests that Thanos did it to save the human race from Galactus, one of Marvel's most powerful characters. Primarily a Fantastic Four villain, Galactus can easily consume the core of a celestial body and destroy it entirely, hence the moniker "devourer of planets." With his ability, he might be another impossible challenge that the remaining Avengers have to face.
