How Old Is Eren Yeager In My Hero Academia Clarified

It's a question many anime fans might find themselves asking, especially given the shared popularity and intense action of both series: "How old is Eren Yeager in My Hero Academia?" The truth, however, might surprise some, as it addresses a fundamental mix-up that’s surprisingly common.
Let's clear the air right away: Eren Yeager is not a character in My Hero Academia. He is the central protagonist of the critically acclaimed series, Attack on Titan.

This doesn't diminish the curiosity, though. Fans often wonder about the ages of their favorite characters, as it directly impacts their development, their struggles, and the stakes they face. So, while Eren doesn't exist within U.A. High's hallowed halls, we can still explore the ages of the incredible cast of My Hero Academia and shed light on Eren Yeager's actual timeline in his own saga.
