At the same time, the fight between the two powerhouses got even more intense,with All Might managing to do further damage to All For Oneand the latter retaliating as well. It appears that the fight has now entered its climax and fans are very excited to see who comes out on top when the dust has settled.
Glimpses of Deku’s Fight
In the previous chapter ofMy Hero Academia, fans got to seea glimpse of Deku and Shigaraki fighting. Since Deku wheels the One For All, a part of All Might is in the Quirk as well. It is thanks to the vestige that Deku was able to figure out that All Might is fighting against All For One to the best of his abilities. Fans did not get to see much of their clash in the previous chapter, however, it is likely that Deku will be even more motivated to triumph over Shigaraki and save everyone that is dear to him, and that includes All Might. All For One is an incredibly powerful entity and a single misstep from All Might could end up being lethal.
Seeing All Might in such a precarious situation is only going to strengthen Deku’s resolve and make him fight to the best of his abilities. After all, if his teacher is trying his best without even having a Quirk, he has no excuses and needs to finish the job. Fans can hope that All Might’s stand inspires Deku inMy Hero Academiachapter 399 and pushes him to higher limits. Of course, the upcoming chapter will not feature the fight between Deku and Shigaraki completely. However, glimpses of it and Deku’s thoughts on All Might taking a stand definitely will be interesting for the fans to see. The vast majority of the focus should still remain on the clash between All For One and All Might.

All Might’s New Form
My Hero Academiachapter 399 will most definitely feature All Might’s new form that he took towards the end of the previous chapter. Fans could see more attachments being sent his way by Hercules and immediately,All Might grew even more versatile in combat.Previously, fans saw All Might utilize various powers that were inspired by the Quirks of his students. In the previous chapter, he also managed to use Acid and damaged All For One to quite a degree. Shortly afterwards, he got two more attachments which gave him two new Quirks to utilize.

This time, All Might received a power-up named Uravity Buster and Ingenium. It is quite clear to see that these two Quirks have been inspired by Ochaco Uraraka and Tenya Iida. These two characters have also played a significant role in the war, however, more importantly, they have managed to inspire All Might, which is why his battle armor has their powers as well.
What exactly these attachments will do remains to be seen, however, it is quite likely that they mimic the powers of the original Quirks. It is likely that, through Uravity Buster, All Might is able to grab a hold of his enemies and make them levitate and then use his other Quirks to land powerful blows on All For One. As for Ingenium, it is likely going to increase his mobility in combat, as well as raise his speed to sky-high levels. All Might certainly needs these power-ups to keep up with All For One and fans will most likely see what these upgrades offer in the next chapter.

All For One’s Attack
My Hero Academiachapter 399 will most definitely seeAll For One use more of his poweras well. He has been on the receiving end of quite a heavy beating and he has been forced to regenerate over and over again. Essentially, All Might plans to make him use the power of regeneration and rewind so much that he ends up reverting to nothingness faster than originally planned. So far, All For One is falling for the bait and potentially even getting weaker in the process. That said, a single strike from him in the previous chapter was enough to damage All Might severely. Fans will most likely see more of that inMHAchapter 399. It is likely that fans will see a bunch more Quirks being combined by him and All Might being at the receiving end of some heavy blows.
While All Might’s armor has been heavily compromised already, he has not taken significant damage just yet. Perhaps, My Hero Academia chapter 399 will focus on that and raise the intensity of this fight by giving All Might a serious injury. If that does happen, then this fight will become even more chaotic and this fight of life and death will look even more intense than ever before. That aside, All For One’s showing in this fight has been rather lackluster. For someone who is beyond his prime at this point, he needs to do better, especially against a man without any Quirk.

The Remaining All Might Quirks
Of course, Uravity Buster and Ingenium are not going to be the only powers that All Might will bust out in this fight. He must certainly have other Quirks up his sleeve as well and that means fans will get to see more attachments coming his way soon. While all the characters in Class 1A are important, there are definitely some who have played more significant roles in the story and are, thus, fan favorites. So far, All Might has not used their powers, however, little by little, he’s starting to use stronger abilities. It is entirely possible for him to pull out abilities that have been inspired by the Quirks of the likes of Bakugo, Todoroki, and also Izuku himself. These Quirks will most likely be his strongest offensive units and allow him to do the most damage to All For One.
It is highly likely that All Might will tap into these powers towards the end of the fight as a last stand, which would mean there is still ways to go in this fight. Fans are expecting stronger abilities from All Might. The power of Explosion would be extremely exciting to see in combat through Armored All Might. At the same time, the power of fire and ice would be very useful in the clash as well. Ultimately, All Might only has one Quirk that he can get the best out of and that is certainly the One For All. How he will replicate that power, or, if he will even replicate it at all, is something that fans are excited to see. The next few chapters should give them the answer to that.
