My Hero Academia is one of the most popular anime to appear in recent years, and for good reason. It tells a compelling story of a young boy's journey to become a super hero, and creates a complex and fascinating fictional world. It offers awesome art and animation, great characterization, and a suspenseful plot that keeps you on your toes.
While the whole series is awesome, not every arc offers the same quality. Which are the best My Hero Academia arcs? That depends on your personal preferences.
Do you like like hot-blooded competitions where the stakes involve success or failure at an important goal? You might like the Quirk Apprehension Test Arc, or the U.A. Sports Festival Arc. Or would you prefer an arc where death is a real possibility? In that case, your favorite might be the Vs. Hero Killer Arc, or the Forest Training Camp Arc.
Episodes 46 - 50
Bakugo has been kidnapped by the League of Villains, which prompts the pro heroes to launch a rescue mission—and also Bakugo's friends, who technically aren't allowed to get involved.
This arc also includes on of the most dramatic battles of the series so far, that between All Might and his nemesis, All For One. Though All For One is defeated and taken to prison, All Might reverts to his true form in front of thousands of people, effectively ending his career as a hero.
The chaos that ensues, as well as the fact that a student was kidnapped to begin with, damages U.A.'s reputation, causing the staff to have to go through multiple press conferences and conduct home visits with all the students' parents in order to restore trust in them as an institution.
Episodes 14 - 21
The sports festival in My Hero Academia isn't like the sports festivals in most other anime. Rather than a simple competition designed to encourage team work and school spirit, U.A. High School's sports festival is a massive, televised event where hero hopefuls show off their skills to hero agencies who might want to take them on as interns or even employees in the future. It consists of three parts: a 4 km obstacle race, a calvary battle, and a fighting tournament.
The arc also features a number of important revelations about the characters and the world. Class 1-B is introduced, showing that U.A. High School isn't just one class. Todoroki and Shinsou's difficult pasts are revealed. Izuku learns that he's linked to everyone else who has ever possessed his quirk, One For All. A new villain, Stain, is introduced, setting that stage for the next arc.
Episodes 39 - 45
Class 1-A and 1-B attend a training camp in the woods. With the help of their homeroom teachers Aizawa and Vlad, along with a pro hero group called the Wild Wild Pussycats, they work to improve and strengthen their quirks.
Unfortunately, the training quickly gets real when the League of Villains shows up with the intention of kidnapping Bakugo. The training camp turns into a no-holds-barred battle between the school and the League. Whether it's Izuku trying to protect a small child from a terrifying villain who joined solely so that he could kill people, or Aizawa trying to hold his own against the mysterious Dabi, these are some of the most high stakes fights in the series so far.
Episodes 26 - 33
After the sports festival, the U.A. students begin internships with pro heroes. Midoriya trains under Gran Torino, one of All Might's former mentors. There, he learns to use All For One throughout his entire body, rather than concentrating it in one body part.
Meanwhile, Tenya Iida chooses an agency in Hosu City, where he believes that he will find Stain, the villain who attacked his older brother Tensei. Despite his straight-laced nature, he finds himself overcome with the desire for revenge. He's unable to defeat Stain on his own, but many of his friends are already in the area thanks to a Nomu attack, and he manages to take him on with Midoriya and Todoroki's help.
