It’s been 3 weeks since Kohei Horikoshi ended the 10-year-long serialization of My Hero Academia on Aug 5, 2024, and fans are still quite mixed with its conclusion.
Most of the dissatisfaction comes from the shipping community, where Horikoshi hasn’t really confirmed any of them, even after the 8-year time skip in the final chapter.
Another significant portion of that dissatisfaction comes from those fans who actually give a damn about the story and the theories surrounding it. One of the key theories Horikoshi did not really dive into is the Quirk Singularity theory and its significance in the story.
A brief summary of the Quirk Singularity theory
The Quirk Singularity is an idea proposed by Dr. Kyudai Garaki 70 years ago regarding the dangers posed by Quirks becoming stronger with each generation.
Since the human body can’t keep up with the rate of evolution, controlling Quirks will become increasingly challenging as their power increases. When Quirks get too complex and powerful, no one will be able to manage them whatsoever. Although this theory’s initial name was Paranormal Singularity Theory, it later went by the name Quirk Singularity Doomsday Theory.
Nobody believed the doctor at that time but as the story progressed, there were signs that the theory might actually be true.
In chapter 347, Tomura Shigaraki was able to sprout hundreds of fingers from his left hand as a result of his Quirks’ mutation, imitating the growth of his Quirks like hair, nails, or skin, indicating that it would be the result of humanity adapting to the Quirks.
However, one fan argues that this proof doesn’t actually solve the matter as it contradicts another theory Horikoshi introduced in the story.
The problem with Horikoshi’s Quirk Singularity theory
Yhhan on Reddit explains that if the Quirk Singularity concept holds true with each generation, then the folks in Class 1-A like Bakugo, Todoroki, and Tokoyami should have mutated mid-battle like Shigaraki, even though they were kinda strong on their own. But nothing of the sort happened.
The Nomus were able to hold multiple quirks but their bodies were artificially mutated by Dr. Garaki just for that very purpose.
What’s more, All for One said this theory applied to him and he was its sole believer but didn’t the theory state that the Quirks would get stronger and harder to control with each generation?
Also, why didn’t All for One experience this form of mutation if it was caused by his many Quirks? Sure, he had some fairly horrific mutations, but only when he activated his Quirks all at once.
These were some of the questions pondered by fans, which led some to conclude that Horikoshi might have confused the Quirk Singularity theory with another idea he introduced – the Multiple Quirk Factors Theory.
This theory suggests that users with more than one Quirk will die at a young age because multiple Quirks can cause a huge strain on their bodies, and hence they age faster.
They further argue that this is the reason why All for One wanted to take over Shigaraki’s body, that Deku is the perfect and last One for All user after All Might’s retirement, and that the former No. 1 hero constantly shrank and bled after using his strength.
This led fans to believe that the Multiple Quirk Factors theory holds more weight than the famous Quirk Singularity theory because the only proof of the latter is when some annoying kids appeared in a movie. Therefore it might not have much impact in the story.
