How Many Characters Know Saitama’s True Strength in One Punch Man?

Saitama is the strongest being in the One Punch Man universe. However, very few people are aware of Saitama’s true strength. This is because he never claims his achievements, and has a more nonchalant attitude towards his unparalleled power, contrary to the flashy nature of some of the other heroes.


But over the course of the story, some characters eventually come to know of it, especially after he joins the Hero Association. Some haven’t witnessed it firsthand, but can sense the immense potential in him. The characters who know Saitama’s true strength in One Punch Man are the following:

  • Armored Gorilla
  • Bakuzan
  • Bang
  • Black Sperm
  • Blast
  • Bofoi
  • Boros
  • Busho
  • Carnage Kabuto
  • Dr. Kuseno
  • Flashy Flash
  • Forte
  • Fubuki
  • Garou
  • Genos
  • Genus Extensive
  • Glasses
  • Geryuganshoop
  • God
  • Hammerhead
  • Jinzuren
  • King
  • Manako
  • Mumen Rider
  • Nyan
  • Orochi
  • Overgrown Rover
  • Phoenix Man
  • Sneck
  • Speed-o’-Sound Sonic
  • Suiryu
  • Sweet Mask
  • Tatsumaki

Some of these characters are Saitama’s allies while some are his enemies. Characters like Garou and Orochi come to know of Saitama’s true strength after fighting the man and having him unleash his powers. On the other hand, characters like Blast, Suiryu and King witness the fearsome strength of Saitama when the man is fighting an enemy.

However, Boros can sense exactly how powerful Saitama is or at least how much potential he has upon seeing him for the first time. Recently, the two characters who get an idea about Saitama’s true strength are the psychic sisters, Tatsumaki and Fubuki. 

When Saitama effortlessly stops Tatsumaki from attacking the Blizzard Group, they get the sense that the man isn’t as plain as he appears. But Tatsumaki still believes herself to be stronger than Saitama.
