One-Punch Man

While their power isn't really all that remarkable, the strongest B-Class heroes in One-Punch Man are still fairly formidable in their own right.

As a B-Class hero who's ranked 3rd, it's safe to say that his physical prowess is similar to that of an A-Class hero. Even his hero name, Glasses, is indicative of how even the most regular person around can still become a hero. Her nickname is "The Shopping Street of Techniques" which reflects the fact that she is able to use several abilities in battle. He's personally crafted a custom piece of armor and equipment for himself that he uses to great effect in battle. Her psychic abilities can be used to unleash a world of hurt on her foes, and there's no telling how much her powers can develop after training them immensely. Not much has been seen of the Pink Hornet, but her decent B-Class ranking means that she's one of the more reliable heroes around. Double Hole is a pretty funny superhero, with his power mainly coming from a cybernetic nose that he uses to fire energy blasts. Most people haven't really seen this hero in a fight, but his relatively high ranking means that he's pretty competent indeed. The many heroes of the series are split into various groups, with B-Class heroes being pretty competent in their own right. In fact, his chemicals are so noxious that he has to wear a mask at all times to avoid getting contaminated by his own creations. His all-black attire is quite noticeable and makes him pretty unique when compared to the other heroes around him. Saitama should definitely be ranked way higher than he is in the rankings, although that's just one of the many reasons why the show is so funny in its own right.
