My Hero Academia Final season leaked trailer bears great news for fans

Few anime finales have been as highly anticipated as the upcoming My Hero Academia Final Season. With Kohei Horikoshi’s manga already wrapped up, fans have been counting the days until Studio Bones brings the climactic Deku vs. Shigaraki confrontation to the screen.

But this week, excitement exploded after Crunchyroll and the official My Hero Academia English social channels briefly uploaded the Final Season trailer a full day earlier than scheduled, before promptly deleting it.

Even though the video was quickly switched to private and removed from X (formerly Twitter), fans wasted no time capturing snippets, analyzing the animation, and flooding online discussions with theories. And based on what we saw, this final chapter in the anime adaptation looks set to be nothing short of spectacular.

The My Hero Academia Final Season trailer wasn’t supposed to be revealed until after Japan’s special “Hero Villain Fest” event on August 17, 2025. Instead, Crunchyroll seemingly jumped the gun, posting the full trailer to both YouTube and X. Within hours, the uploads were gone, but the damage, or perhaps the blessing, was already done.

Though the leaked trailer was quickly pulled, fans won’t have to wait long for the official version. With “Hero Villain Fest” taking place on August 17 in Japan, it’s almost certain that the trailer will be re-released, perhaps with additional announcements.

From there, all eyes are on October 4. The final season will air weekly on Sundays at 5:30 p.m. JST and will stream globally on Crunchyroll. With the anime reaching its conclusion, the fall season looks set to be dominated by Deku, Shigaraki, All For One, and the heroes and villains who have defined this saga.

Animation that left fans speechless

The number one takeaway from the leaked footage? The animation quality. Fans who managed to watch the trailer before it disappeared immediately praised Studio Bones for pushing their work to new heights. Comments across Reddit and X were filled with reactions like:

It’s clear that Bones is holding nothing back for this last hurrah. From fluid, dynamic fight choreography to jaw-dropping art direction, every second of the teaser screamed final-season grandeur.

And yet, fans noted the studio was deliberately holding back major moments, suggesting the best is still being saved for broadcast.
