In One Punch Man , strength isn't everything—at least not officially. Before any decisive punch, there's a rigid system that organizes, evaluates, and positions each hero within the Association. And it's precisely this structure that creates rivalries, frustrations, and absurdly funny situations throughout the plot.
To better understand how this mechanism works—and why it's so important to the story—we've put together a straightforward guide covering all the hero classes, their criteria, and what it really means to climb (or fall) in the rankings. Let's dissect this system that often weighs more heavily than any villain.
Almost all of them need to be properly registered with the Hero Association , which ranks them into 4 Classes according to their abilities. These are: Class C, B, A, and S. Furthermore, they are also numbered for more precise ranking, and currently the list for each Class is as follows:
- In Class C we have – 390 heroes
- In Class B there are already – 101 heroes
- Class A – 38 heroes
- And finally, in Class S we only have – 17 heroes
On the other hand, our protagonist initially managed to qualify as a Rank C hero simply because he did poorly on the written exam. However, his student Genos managed to qualify directly for the elite rank of heroes!
Class C
First, let's talk about the lowest-ranked Heroes. However, even they possess above-average power compared to the general population. Furthermore, they must all perform weekly heroic acts to avoid being removed from the Association's list. Incidentally, the highest-ranked Class C hero at the moment is our beloved Mumen Rider.
Class B
Now, moving up a level, we have these guys who don't need to meet any weekly quotas to keep their positions. Furthermore, here we can already find Heroes with considerable power, even if they are far from the other two Classes. Finally, it's worth remembering that currently the number 1 position in Class B is held by the powerful Fubuki!
Class A
Here we see the second strongest Class of all. Thus, we have many very powerful Heroes here, and several of them are extremely popular in society. In fact, with fewer than 50 people here, we can certainly imagine the level of power they possess. Not to mention that currently, the one occupying the top spot in this Class is the great Sweet Mask.
S-Class
And finally, the most prestigious and powerful class of all four. Where each one has power equivalent to an emergency division of the army! Moreover, with only 17 of them available, we already know that they are beings on a completely different level from the others. Thus, we can also highlight Blast, which is currently seen as the strongest of all!
