What Do We Know About the One Punch Man Main Characters’ Ages?

The exact ages of all of the One Punch Man characters have been pretty straightforward for the most part – particularly for characters who are classified as human or are predominantly human. All of the human or mostly human One Punch Man characters appear to mature normally, following one linear and uniform timeline, much like humans would age in real life.

Of the human One Punch Man characters, Child Emperor is the youngest hero at the ripe age of only 10 years old, followed by some talented heroes and villains who identify as adolescents. Specifically, these characters include Bad Metal Bat, who is 17 years old. The infamous One Punch Man villain Garou is 18 years old in the storyline, and Genos is 19 years old.

The majority of the main One Punch Man characters and most proficient heroes are in their 20s overall, however, including Fubuki, Saitama’s potential love interest who is 23 years old. This is followed by the star protagonist Saitama, the villain and occasional anti-hero Speed-o’-Sound Sonic, and Mumen Rider, who are all 25 years old, and Tatsumaki, who is 28 as well as King, who is 29 years old.


15 Strongest One-Punch Man Characters (RANKED)

Some adults also comprise the list of main or favorite One Punch Man characters, such as Puri Puri Prisoner, who is 33 years old, and Bang, a skillful senior at the seasoned age of 81 years old. Blast, the Rank 1 professional within One Punch Man’s Hero Association S-Class, is currently listed with an unknown age – still, many fans expect him to be in his mid-30s, at least due to his sheer level of experience and skill, although this is purely theorizing at the time of writing.

However, things are more complex when it comes to identifying the exact ages of otherworldy beings in One Punch Man, as the saga is riddled with other species and beings with more secretive origins. One such case is the infamous Lord Boros, one of the primary antagonists throughout the One Punch Man storyline, who is classified as a “Mysterious Being” within the saga – as such, we do not know as much about this character’s background compared to many others.

It is known that Lord Boros is at least 150 years old, but many fans speculate that he could be significantly older than what is known – potentially in the higher hundreds or even over 1000 years old, depending on perspective and opinion. A few fans have pointed out that his overall demeanor gives the impression of a being that’s much older, and this same logic could apply to some other characters listed as Mysterious Beings as well.

Some of the most notable points here include the fact that he treats 20 years like a short weekend in terms of time span, and he also spends time with Melzargard, who is around 500 years old. Many have also argued that his galactic travels would have likely taken hundreds of years, seemingly much longer than his reported total lifespan to date. So, while he may only be 150 years old according to the One Punch Man characters, he could potentially be ancient concerning his true age.
