How Old Is All Might in Code Geass, Really?

It’s a question that sparks curiosity and, perhaps, a chuckle among seasoned anime fans: "How old is All Might in Code Geass?" The short, definitive answer is that All Might does not exist within the Code Geass universe, and therefore, he has no age there. This fascinating query stems from a common, yet understandable, mix-up between two vastly different, incredibly popular anime franchises.
All Might, the iconic Symbol of Peace, is the cornerstone character of My Hero Academia, a world teeming with superpowers known as Quirks. Code Geass, on the other hand, immerses viewers in a complex alternate history filled with mecha battles, political intrigue, and the mind-altering power of Geass. These two titans of anime reside in completely separate narrative universes, never crossing paths in any official capacity.
So, if you're picturing the muscular hero clashing with Britannia's Knightmares or advising Lelouch Lamperouge, it's a fun thought experiment, but not canon. This hub is here to clear up the confusion, guiding you through the distinct worlds of both All Might and Code Geass, so you can appreciate each for its unique brilliance.

Understanding All Might: The Symbol of Peace's True Home

All Might, real name Toshinori Yagi, is the quintessential superhero from Kohei Horikoshi's My Hero Academia. He’s not just a powerful individual, but a living embodiment of hope and justice for an entire society. His very presence once brought Japan's crime rate to an astonishing low. To truly understand the man behind the myth, it’s crucial to separate him from any imagined crossovers.
Born Quirkless, All Might defied expectations when he inherited the incredible power known as One For All from his mentor, Nana Shimura.

To truly understand the true power of One For All, you need to see how it shaped All Might's destiny and the legacy he created.

All Might's journey is far from easy. Five years before the main My Hero Academia storyline, he suffered devastating injuries in a brutal confrontation with the arch-villain All For One, losing significant internal organs.

Despite his waning health, All Might's resolve never faltered. He remained a beacon of hope, inspiring countless individuals, including his eventual successor, Izuku Midoriya. His decision to pass on One For All to Izuku and his subsequent retirement from active heroics marked a pivotal moment in the series. To learn more about his pivotal role mentoring Izuku Midoriya is to understand the depth of his commitment to the next generation of heroes.

Code Geass: A Universe Apart

In stark contrast to My Hero Academia's world of heroes and Quirks, Code Geass unfolds in a gritty, politically charged alternate reality. Here, the Holy Britannian Empire dominates the globe, and the story centers on Lelouch vi Britannia, a deposed prince who gains the supernatural power of Geass and leads a rebellion against his father's empire. There are no Quirks, no Symbols of Peace, and certainly no All Might.
Instead, Code Geass features giant humanoid war machines called Knightmares, complex strategic battles, and a morally ambiguous protagonist grappling with the consequences of his power.
