All Might's New Power, explained

This article contains spoilers for My Hero Academia Season 7 Episode 21.

In the world My Hero Academiacreated by Kohei Horikoshi, All Might has always been an integral part of the story. Listed in the world My Hero Academia as the greatest hero who ever lived and Japan's number one hero, All Might was an idol that everyone looked up to and a symbol of peace that society held tightly to.

Children like Bakugo, Shoto, and of course the main character of the story, Izuku, looked up to All Might growing up and idolized him. He was the reason a generation of aspiring heroes joined the prestigious Hero Academies in their quest to become a hero, and he became the impetus for every beloved protagonist to embark on the journey. However, as the story progressed, All Might's journey itself became quite problematic. He ended up losing the vast majority of his powers and eventually all of them. Crippled and for the first time in need of protection himself, All Might became a shadow of his former self. Yet now, as shown in the events of My Hero Academia chapter 386, All Might is back again.

Updated by Rei Penber on October 12, 2024: All Might is determined to stop All For One, despite his weakened state. To achieve this, he will use his newest ability in MHA Season 7. All Might, a fan-favorite character in MHA, gets his time to shine in his final battle.

How could they all lose their power

All Might gave his power to Deku

All Might was known as an incredibly powerful hero who deserved to be number one at the beginning of the story. However, it wasn't until much later that it was revealed to fans that All Might was actually very low, especially after All For One injured him during their fight, which he ended up winning. Due to his serious injury, All Might was no longer able to fight at his best for a long time. Because of this, he began looking for a successor, initially setting his sights on Mirio. However, in a twist of fate, Deku proved his selfless nature as a hero and became the next user of One For All.

When All Might switched to One For All, whispers of that power remained in his body and eventually burned them all at Kamino, where he fought All For One for what seems to be the last time. Standing tall as the greatest hero of all time, All Might pushed past all his limits and ended All For One's tyrannical reign, sending him to Tartarus. This finally ended his era and he lost all of his powers, meaning that Deku now had to carry the Society of Heroes on his back.

All Might In The Final War

All Might Takes on All For One

After losing his powers, All Might was crippled to the point where he couldn't fight even the weakest of villains. His power level was nowhere near what it was before, and even his stamina had suffered terribly. His injury prevented him from performing the most basic of combat-related activities, and it was quite clear that he could not play the role of hero again. Endeavor, the number two hero before him, ended up in the number one position and tried to fill All Might's shoes. While he did fairly well, he wasn't All Might.

For All Might himself, the feelings of helplessness became more apparent as time went on, and for someone who carries the entire Hero Company on his back and saves everyone with a smile, being so helpless must have been a crushing blow. All he could do was entrust everything to the next generation of heroes and hope for the best, which he did for the vast majority of the story from when he lost his powers to the Final War Saga. Even as All For One and Shigaraki rioted on the battlefield and Heroes were dying left, right and center, All Might could do nothing but watch. However, this changed towards the climax of the arc where he finally got into action.

All Might's New Power

Armored All Might Comes In

When All Might heard that All For One was getting stronger and even surpassed his best self, he couldn't just sit back and watch. They saw him order Shoto and Iida to chase Dabi and leave All For One to him. Even though he had no Quirk, he went into battle with the strongest form of All For One and did so with immense confidence in his abilities. Eventually, Deku, who was once a quirkless boy, became his hero. In his Quirkless state, Toshinori could only look up to the boy who had burst into tears that fateful day and asked him if he could be a hero.

All Might asked himself the same question and set out to fight All For One. While fans may think that he will be manipulated, or worse, even die in this fight, it is important to remember that All Might will not be left empty-handed. He appears to be carrying some sort of Hero Equipment. This equipment would likely be built by Mei Hatsume, and if one had to guess, it could be a full body suit made to allow All Might to return to a reasonable level of power. From what fans saw in the previous chapter, Toshinori had a briefcase with him which he broke once he saw All For Ond. It is possible that there is armor inside this briefcase that would surround his body and allow him to fight All For One to the fullest. Either way, All Might doesn't go into battle helpless and defenseless. He has a power he intends to use, and since he, like Deku, wants to change fate for good, All Might won't die and will do more than enough to keep All For One at bay.

My Hero Academia season 7 episode 21 is scheduled for release on October 12, 2024. MHA Season 7 Episode 21 can be streamed on Crunchyroll and will air at 2:30 PT/5:30 ET.
