The following contains spoilers for My Hero Academia Season 6, Episode 7, "Disaster Walker", now streaming on Crunchyroll, Funimation and Hulu.

Tomura Shigaraki has just returned in the sixth season of My Hero Academia, and he is stronger than ever. Despite his rushed awakening, Dr. Garaki's procedures prove to be potently effective. Shigaraki has essentially been turned into the perfect Nomu, complete with superhuman strength and miraculous regeneration. At present, Shigaraki can easily match Endeavor's firepower even with Eraser Head keeping his quirks at bay.

Just as Shigaraki acquires great power with Dr. Garaki's help, he also experiences moments of acute headaches. It first occurs after Shigaraki unleashed his newly-improved Decay quirk. The villain has been ignoring the headaches, but he may no longer be able to do so. It seems that All For One's consciousness is already slowly creeping into his.

The fight between the top-ranking heroes and My Hero Academia's worst villain continued to escalate. Eraser Head, supported by Manual, kept the villain from utilizing his multiple Quirks. Meanwhile, Endeavor and the other powerful heroes continued to rush him. But even after Gran Torino joined in, they still couldn't take the villain down. Shigaraki then shifted his attention toward Eraser Head, since the hero's quirk was starting to annoy him. The villain almost got to him, but Midoriya and Bakugo blocked his attack.

With Midoriya joining in on the fight, Shigaraki began focusing on him. He wanted to grab Midoriya and escape. That was when another episode of his acute headache happened. This time, he heard a voice commanding him to seize One For All. Immediately afterward, Shigaraki's expression changed. He then said, "You shall be mine, little brother." Both Shigaraki and Midoriya perceived the sudden change in perception. Shigaraki confirmed that he wasn't the one who spoke those words, then immediately acknowledged the strength of his master's consciousness.

What Is Likely To Happen To The Two Villains?

The main reason All For One is grooming Shigaraki is for the young villain to be his vessel, and Shigaraki is aware of it. The other reason is that All For One desires the boy to finish what he has tailed to do -- seizing One For All. In order to do that, All For One has been raising Shigaraki to be the perfect successor. He not only provides him with power, but he has also been teaching him how to master them. Finally, his efforts have borne fruit.

Shigaraki is already unmatched in the world of My Hero Academia. As such, All For One is starting to make his consciousness known. It won't be a surprise if he suddenly tries to possess Shigaraki's body. However, Shigaraki isn't going down without a fight. The young boy has made it clear in Episode 7 of Season 6 that he is the owner of his body and power. It is hard to imagine that the boy will simply surrender himself. And so, there are two likely outcomes.

It is possible that All For One and Shigaraki will be engaging in a tug-of-war over the possession of Shigaraki's body. After all, it is revealed that All For One's consciousness can already assimilate with the body -- albeit momentarily. If this is to happen, then the two may momentarily weaken themselves and give the heroes an opportunity to strike. Another possible scenario is the two reaching a compromise. They may decide to share the body. It is possibly by taking turns, coexisting like Kurama and Naruto, or fusing their consciousness into one. Whatever the case may be, they will still remain the worst and most powerful villains in the world of My Hero Academia.
