It’s funny that ever since Avengers: Endgame hit the theatres, these theories have kinda died because no one really knows about the grand plan of Marvel in the next 3-4 Phases. From what it looks like, the Phases are going to run for a shorter span of time now since the Disney+ Series will also be canon to the MCU. So, we can actually expect multiple boss villains. But there has to be one big bad running things like Thanos did. There are several villains who could replace Thanos, but Galactus will obviously be the first name on everyone’s minds.
Logically, the upcoming Phase 4 films will be setting up this next big bad, but what if the seeds for Galactus have already been planted? There’s this new theory which suggests that Thanos actually had another insurance in play when he snapped his fingers a second time to destroy the stones themselves. This theory coming from Reddit user UpwardSpiral00 says:
“So I’ve been thinking a lot about Thanos lately, and how he seemed to have such resolute conviction about destroying the Infinity Stones after his snap, to prevent them from being used to undo his culling of the universe. And something didn’t sit right with me.
Thanos is a smart guy. He’s worked hard for decades on his crusade to balance the universe. He may have even used the Time Stone to look ahead and see his death at the hands of the surviving Avengers. But he didn’t seem concerned about his great work being undone. And yet, it would be, even just with nature running its course.
The world population in 2018 was roughly 7.7 billion. Thanos snaps, we’re down to 3.85 billion, or roughly the global population at the end of 1972. So in 46 years, about half a human lifetime, the population would bounce back. And presumably this would be a similar scenario replayed on other planets in the MCU that survived the snap enough to bounce back. Surely this would have occurred to someone as smart and methodical as Thanos.”
What the Redditor is suggesting here is that Thanos obviously wasn’t as stupid. He must have known that people might not succumb to his will. Some might resist the form of justice bestowed upon them. While he did think that removing the stones out of the picture would let people believe that they’ve lost. But there still needs to be a backup. The Redditor continues:
“And even if he didn’t foresee his own death, he would have understood that without the stones, life would be free to run rampant again. So my theory is, as part of his plan to remove the temptation of the stones but still ensure his great work would not be in vain, he created an insurance policy, at the same time that he was destroying the stones. An agent of destruction that would keep life in check by not only being a cosmically powered force of nature that mere mortal heroes couldn’t surpress, but also by using burgeoning populations and biospheres for its own sustenance. A world devourer.”
Now, this could be a great way to bring Galactus into the picture. He has the capability to be an even bigger villain than Thanos ever was (quite literally). Since Disney has got hold of the major Fox properties, Marvel could easily use villains like Doctor Doom, Galactus, Apocalypse and combine them with the likes of Annihilus, Kang, Maestro and many more.
