The Science of My Hero Academia

Shota Aizawa is the beloved(and feared) homeroom teacher of Class 1A. As a pro hero, he goes by Eraser Head. A fitting name given his quirk, which is remarkable even by the high standards of UA academy. His power, Erasure, allows him to deactivate people’s quirks just by looking at them. In a world full of beings who can easily overpower ordinary people, he can even the playing field and change the course of many battles in an instant. This ability combined with his combat prowess and physics-defying capture bands makes him an extremely formidable opponent. Aizawa’s quirk is an…

Aren’t you dazzled? If not, you will be because today we’re looking at the magnificent power of Yuga Aoyama. Like many powers in My Hero Academia, Aoyama’s quirk compliments his personality. Like him, it stands out for its grace and aesthetic. Under the moniker Navel Laser, this ability allows him to fire powerful beams of sparkling blue light from his midsection. He can use said beams to heat up and bore through materials, knock back opponents, propel himself backwards, or simply illuminate an area. Only, hold on. That’s not how lasers work at all!

In fact, Aoyama’s quirk belongs to…

Welcome back to my series on the science of My Hero Academia. Today, we’ll be diving back into the science behind Ashido’s quirk, Acid. Last time, we looked at the chemistry that allows this hero’s acids to quickly corrode targets. Today, we’ll be looking at the physical properties her acids can take on and the deeper intermolecular physics behind them. I highly recommend checking out my last post on Ashido’s quirk and/or my post about where quirks come from to begin with. They’ll both be valuable pieces of today’s investigation.

Are you ready? Great. Let’s begin…

How Does Ashido Shoot Acid?

The Science of My Hero Academia

Mina Ashido is energetic, creative, great at breakdancing, and at any moment, she can produce a highly corrosive acid. Just your everyday above-average high school student. Her quirk has always fascinated me because despite bolstering a wide range of applications, it’s not a very common power across superhero media. The science of dissolving substances with acid is also very nuanced, which makes me super excited to dive into it. (The science, not the acid.) Let’s look at everything Ashido can do with her acid and see what science has to say about it.

How Engineers are Catching Up to the Amazons

As far back as I can remember, I’ve loved swordplay. I went through toy sword after toy sword after toy lightsaber. As I grew older, I even dabbled in fencing. However, none of the swords I used did the main thing swords were invented to do: cut. I’ve never wielded a sharp blade, nor do I really want to. However, cutting is an interesting application of physics. And like all physics, it goes completely off the rails in comics. I’m referring, of course, to Wonder Woman’s signature sword. In the graphic novel Kingdom Come, it’s revealed that her sword can…

The Evolution of Fictional Organisms — Pt. 3

Evolution is how all the beauty and complexity of life emerges. It’s arguably the most powerful concept for explaining everything life can do. To that end, the question arises: what’s the limit? Just how much can evolution accomplish? Are there planets where people regrow limbs in a matter of seconds? What about planets with trees the size of skyscrapers or trees that walk and talk? In my last couple posts, I’ve been using the guiding principles of evolution to gain insight into how beloved fictional creatures could arise in our non-fictional world. …

Would teleportation transport you or kill you? And what exactly are “you” anyway?

Has the pandemic made it harder for you to travel? Well, do I have the perfect product for you! From the outside, it looks just like a telephone booth — you know, those small rectangular rooms with coin-operated machines inside, that people used to use way back before smartphones existed. But go inside, tap a screen, and type in an address, and the whole room will start to scan you. Long rods of light move up and down each wall, and then — just for an instant — it’s like you’re not really there.

You know the feeling: it’s the…

The Evolution of Fictional Organisms — Pt. 2

Alright. You know the deal. What countless Pokémon games, movies, and anime episodes call “evolution” doesn’t resemble evolution by natural selection in the slightest. Rather than inheriting helpful adaptations perfected over many generations, individual pokémon “evolve” by changing their physical traits almost instantly. Ignoring the terrifying implications of pokémon sucking up enough mass to change into their larger forms in a matter of seconds — Game Theory already covered that in-depth —what’s really going on when pokémon “evolve?” And what does actual Darwinian evolution have to do with it?

This is a continuation of my series on the evolution of…

The Evolution of Fictional Organisms — Pt. 1

If you’ve read my previous posts on hypothetical dragon biology, you may be wondering why I’m talking about them again. Well, there’s something very, very important that I missed in my previous analysis: the fitness landscape. The fitness landscape is a fundamental characteristic of evolutionary biology where organisms can’t evolve particular phenotypes, or observable characteristics, unless every random mutation that leads to those phenotypes is independently advantageous. Let’s say an animal begins to develop longer fingers, which could eventually lead to its descendants growing wings. Even if the ability to fly would be beneficial for those descendants, it might get…

Minor Spoilers for My Hero Academia Seasons 1–4

Shoto Todoroki has one of the most powerful quirks in My Hero Academia. From his right side, he can instantly produce mountains of ice. From his left, he creates fire so intense the heat can be felt across a stadium. Today, I’d like to investigate how this power works and examine all the coolest(and hottest) things Todoroki can do with it.

I’ll be working under the assumption that quirks result from highly specific instances of long-range quantum tunneling — the process of matter and energy popping from one location to another because of the fundamental uncertainty in their position— and…
