All For One is the most heinous criminals in the world of My Hero Academia and he is the mastermind of every bad thing going on in the story. As described by many others in the past, All For One is evil incarnate and has managed to pull the strings from the shadows for years. The majority of the crimes taking place in the world of My Hero Academia are solely down to him and, as s uch, his threat is far bigger than anyone in the entire story. At the beginning of My Hero Academia, All For One is revealed to have been dealt with by All Might, however, not killed.

This allowed him to plan for his restoration to power and he has now accomplished that, albeit temporarily. In the Final War arc, All For One was able to revert to his old form and temporarily turn back the clock on his body. He is now in his prime state and, as expected, is much stronger than ever before with powers that he didn't have access to until now.

5 More Speed

Expectedly, with a younger body comes a ton of boosted physical attributes and speed is certainly one of them. Speed plays a significant role in fights in My Hero Academia. For instance, All For One tracked the amount of time it took All Might to get to Kamino when the two fought and he was able to deduce from it that the latter had grown significantly weaker than when they previously fought. In his fight against Endeavor, All For One was made to take some damage and all this could have possibly been avoided had he been faster.

Now that he has turned back the clock on his body and returned to his prime state, All For One is faster than ever before and this could easily make him the fastest character in My Hero Academia. While his speed remains untested, it goes without saying that a character as strong as him would now be an even bigger threat.

4 More Power

Another physical attribute of All For One that gets boosted with him returning to his prime is his power. All For One possesses a significant amount of power and this has already been demonstrated across his many fights in the story. To start with, he has murdered nearly every other vestige of One For All and in his fight against All Might, he proved to be strong enough to deal to him a significant injury.

In their fight in Kamino, All For One once again displayed his tremendous strength and power when the two clashed and this attribute of his will now be boosted to an entirely new degree. In his prime body, All For One was strong enough to lethally wound All Might in his prime and now, this strength of his has returned.

3 Ability To Store More Quirks

The greatest attribute that All For One possesses is his Quirk which also goes by the name of All For One. This Quirk allows him to steal and stockpile Quirks in his body and use them to his benefit. He can also distribute them among people, making him a god of Quirks of sorts. This power of his was severely limited due to his physical condition. All For One was only able to store a limited amount of Quirks in his body until recently.

Now that he has returned to his prime, the number of Quirks that he can store inside him will most likely have increased. This means that All For One is now far more dangerous than ever before as he can make use of new and unique Quirk combinations that make him a menace to the Hero Society. Fans have already seen him combine various quirks across as many fights in the story so far, and this power of his will now be elevated to an entirely new degree.

2 Ability To Use More Quirks

Along with the power to store more Quirks within his body, All For One will also be able to use more Quirks at the same time now. This is an incredible power-up for him. Until recently, All For One was seen making use of several Quirks at the same time to try different combinations and they made him extremely versatile in combat. Whether it was the ability to augment his muscles or increase the amount of kinetic energy that he releases, All For One can mix and match several Quirks and give rise to a new power. His previous combinations were so great that even all my struggled to deal with them.

Now, this power is boosted to a level that fans have never seen in the story so far. All For One can now activate even more Quirks at the same time, making his combinations even deadlier. While fans have not gotten a glimpse of this ability of this just yet, it is only a matter of time before he unleashes his wrath on the likes of Hawks and Endeavor. Undoubtedly, this is one of All For One's greatest assets at the moment.

1 Better Quirk Control

Apart from all the augmentations that his physical body and his Quirk have received so far, thanks to his body returning to its prime state, All For One is also simply a better user of his powers now. Being in his prime body allows him to control his powers better. It goes without saying that now, All For One is faster, stronger, more durable and agile than ever before. Consequently, he knows that his body is capable of a lot more now, which in turn allows him to use his Quirk in ways that he couldn't even have imagined before.

All For One's aging body was rusty and didn't let him exercise the power of All For One to the fullest. Whatever control he once had over this Quirk would surely have waned over time. The fact that he was still such a menace only goes to show how dangerous he truly is. However, now that prime All For One has returned, his control over his Quirk has been restored to as it once was during his prime days.
