Chapter 399 recap

My Hero Academia chapter 399 began with All Might assessing the current situation as he began using several new attachments, all named after Class 1-A students. After confirming that repeated massive damage does shorten All For One’s lifespan, he decided to lay a trap, sending the Anima birds to fetch something for him from Hercules.

All For One then began assaulting All Might with various Quirks, saying he was even conserving power while doing so. He damaged some of All Might’s attachments in the process, eventually ambushing him and saying he has no light left. The scene shifted to another battlefield as All Might said another would pick up his light, where Yuga Aoyama had seemingly been defeated by the Tartarus escape, Kunieda.

Aoyama fired off his Quirk despite not having his belt, initially missing Kunieda. However, Toru Hagakure then appeared, redirecting Aoyama’s lasers into a direct hit on Kunieda, defeating him as a result. The scene then cut back to All Might versus All For One, where the Anima robots had brought back what appeared to be a motorcycle version of Hercules. The issue ended with the floating motorcycle launching a massive beam attack called Can’t Stop Twinkling.


What to expect (speculative)?

Following what’s expected to be a massive blow to All For One, My Hero Academia chapter 400 will likely see him reverse his age even further as a result of the latest damage he sustained. While fans can expect him to try and counter or escape, All Might will likely find a way to land another massive attack on him, possibly with an ability that mimics Hagakure’s Quirk.

From here, My Hero Academia chapter 400 is likely to establish that both All Might and All For One are on their last legs. Both have spent a tremendous amount of energy fighting each other, with each landing severe blows of their own throughout. With All Might’s latest attack is likely to put the two on an even level in terms of stamina, truly anything could happen in the upcoming final round.
