How Old Is Genos in My Hero Academia?

It's a fantastic question that many anime fans might find themselves asking, especially given the shared themes of heroism and incredible power in popular series! However, let's clear up a common misconception right away: Genos is not a character in My Hero Academia.
Genos, the "Demon Cyborg" and faithful disciple of Saitama, hails from the action-comedy anime and manga series One-Punch Man. He's an iconic character in his own right, known for his powerful cybernetic enhancements and his unwavering dedication to justice, often leading to spectacular — and sometimes disastrous — fights. While both My Hero Academia and One-Punch Man feature a world brimming with superhuman abilities and heroic endeavors, their universes and character rosters are distinct.
So, if you're looking for Genos's age, you'll need to explore the One-Punch Man canon. But if your original intent was to understand the intricate timeline and character ages within the beloved world of My Hero Academia, you've come to the ultimate hub! We've meticulously compiled everything you need to know about the ages of Class 1-A, the Pro Heroes, and even the villains who challenge their world.
