The Metapocalypse
So when the series ended, I saw that a handful of fans were confused or disappointed about a certain plot point being resolved. That being the Quirk Doomsday Theory. I saw many fans follow that this idea would be important to the manga somehow. Now, I could easily dismiss this as fans latching onto something when the author never intended it to be that important. However, I still wanted to discuss it. Because I do think that there is something to this concept, but not in the way that everyone seems to think it is.
The Quirk Singularity, or the Quirk Doomsday Theory, is the idea that Quirks become stronger with each generation as they begin to intermingle with one another. And, when these Quirks grow too strong, more complicated, and dangerous to handle. The Quirks as a whole would grow to the point where people and society at large would not be able to handle them. Now, there isn't any denying that something like this is happening. There are a lot of examples of Quirks getting strong as time passes. There are the kids that Bakugou and Shoto work with, there's evidence from Destro's book about kids beating their parents during mock battles, and the absurd heights of the kids of Class 1-A. So it's clear that the manga is pushing the idea that Quirks are getting stronger.
However, the "doomsday" part of the theory is a lot more questionable. Of the Quirks we've seen, there haven't been any major examples of Quirks being too dangerous from the previous generations. Just look at all the pro heroes and the students. They all have their own downsides, but none of them are so strong as to be an active, uncontrollable threat to themselves and anyone around them like the theory is suggesting. What examples we do have are questionable. Tomura and Aoyama were originally the prime examples of this. However, it was eventually revealed that Tomura and Aoyama were given their Quirks. It's an unnatural process, one that their bodies were designed for. They hardly seem like the most fitting examples now.
I would argue the best examples are Dabi and Eri. Yes, their Quirks are dangerous, both to themselves and other people. Yet again, though, Dabi is a result of a very specific combination of powers. Two powers that are active counters to one another and have a very high chance of going wrong. If anything, he could just as easily be used as an example of Quirks potentially getting weaker when they intermingle. Eri is a deviation as well. Her power is so far out of the scope of the setting that I'm not even sure if it counts. Even then, they aren't a threat to the world at large. With the right help, whether it be through training their powers or giving them the right equipment, they could easily live among everyone else. Shoot, you could snap off Eri's horn, and her power becomes harmless.
The only person who really pushes for this idea is Dr. Garaki himself. And yes, Garaki is the number one authority on Quirks in the series. If anyone can have any say on what is happening with Quirks, it's him. However, he's also the guy who made the theory. Of course he's going to see everything as confirmation for his idea, like what's happening with Tomura or the drug made from Eri. All while cackling like a madman about it. He isn't exactly an unbiased source. Especially since a lot of what supported his theory he had some hand in, such as Tomura's bizarre body modifications. There's a reason why people keep calling him crazy, like Present Mic. Because when you really look at the theory and compare it with what we've seen, it doesn't line up.
So, what is the point of all this? Why introduce this theory outside of some neat worldbuilding? I think it has more to do with the themes of the story than being any kind of plot point. The only two people who believe in the idea are All For One and Garaki. Two old, long-lived men who want nothing more than for things to regress and stagnate. That's the whole point of them as villains. The Quirk Doomsday Theory is supposed to show the villain's stance against progress. That it's something to be feared. However, the series runs counter to this. That people shouldn't be afraid of things progressing. That older generations should be working to cultivate and help the next generation grow. It's why when it's first introduced, it's when Bakugou and the gang are doing that exact thing with all the troubled kids.
