Prime All Might's Power As Fans Know It

  • All Might Was The Strongest In His Prime
  • All Might Could Defeat All For One

Fans know very well that All Might is known to be the strongest Hero in his prime. Fans only saw All Might in his prime briefly in the story, and when MHA begins, he is way past his best. In combat, fans have never truly seen All Might at the peak of his powers, but fans do have a good idea of how strong he was. When All Might fights and beats the Nomu in USJ, he states that it took him over 300 punches while in his prime, it would've taken him only 5 punches.

In my prime days, it would've only taken 5 punches. — All Might

At the same time, when All Might fought All For One in Kamino, it was once again highlighted that he was far weaker now, and that in his prime, the battle would've wrapped up long ago. All Might still beat All For One, but his prime self was always going to be on another level entirely.

Horikoshi Confirms Prime All Might's Speed

All Might Could Run At Mach 10

Kohei Horikoshi always gets questions about All Might's powers in his prime, and this fanbook was no different. He was asked about the speed of Prime All Might, or more specifically, the fastest that he has ever run. To that, Horikoshi clarified that he could run at Mach 10.

Question: What's the fastest speed in kilometers All Might has ever run?

Horikoshi: Mach 10 levels of speed (12,348km/h)

Mach 10 is already incredibly fast and just by him running at that speed, there would be large-scale destruction around him, given that this speed is 10 times the speed of sound. But, what's crazier is that this is only the fastest that All Might has run, not the fastest he can go. In fact, in My Hero Academia, it is stated canonically that All Might restrains himself while moving so as to not destroy everything around him. This means All Might can move at speeds far greater than Mach 10 if that's the speed at which he's suppressed.

It's alright. Why? Because I am here! — All Might

How Fast Can All Might Go?

While Mach 10 is definitely the fastest he's run, he can definitely go even faster. His reaction speed and combat speed can easily be higher, and that's what makes him a force to be reckoned with. If All Might is ever fully unrestrained, then even Mach 10 wouldn't be a comparison for his full speed. Unfortunately, fans will likely never know.
