The anime scene in 2025 was nothing short of explosive. From long awaited adaptations to blockbuster theatrical releases, the year delivered a wave of high impact shonen titles that reignited excitement across the global anime community. As the year comes to a close, fans are already looking back on what many consider one of the strongest anime years of the past half decade.
After several uneven seasons, 2025 felt like a full scale comeback. While ranking the best anime is always subjective, some series stood out so clearly that their impact is hard to dispute. For battle shonen fans in particular, this was a golden year packed with visually stunning fights, emotionally charged storytelling, and ambitious world building.
Here are the five most notable action shonen anime of 2025, titles that did not just perform well, but truly made waves.
1. Gachiakuta
One of the most striking newcomers of the year, Gachiakuta premiered at the very start of 2025 and immediately set itself apart. With Part 1 concluding in December, anticipation for a second season is already running high.
What makes Gachiakuta stand out is its bold visual identity, unconventional setting, and relentlessly satisfying action. The series strikes an impressive balance between fast paced combat, a clearly defined power system, and genuine emotional weight.
Set in a seemingly utopian floating city, the story follows Rudo, a young man falsely accused of murder and cast into a nightmarish abyss where society’s waste is discarded. This garbage hell becomes the stage for his fight for survival and revenge.
Dark, gritty, and intense, Gachiakuta carries echoes of Jujutsu Kaisen while carving out a distinct fantasy atmosphere of its own. For fans who crave heavy themes and brutal action, this was one of 2025’s must watch series.
2. Chainsaw Man
Talking about battle shonen in 2025 without mentioning Chainsaw Man would be unthinkable. This year marked a major milestone for the franchise with the release of Chainsaw Man The Movie Reze Arc, which dominated both box offices and streaming platforms.
At its core is Denji, a dirt poor teenager living with his Devil companion, Pochita. After a fatal betrayal, Denji is resurrected through a fusion with Pochita, becoming the Chainsaw Devil. Thrown into the world of Devil Hunters, he must fight grotesque threats while proving he is more than just a monster.
Known for its chaotic action, unapologetically mature tone, and trademark gore, Chainsaw Man continues to push the boundaries of shonen storytelling. In 2025, it further cemented its status as one of Shonen Jump’s most defining modern titles.
3. Demon Slayer
Few franchises command attention like Demon Slayer, and in 2025, the series entered its long awaited final phase. The Infinity Castle feature film not only thrilled fans but also surpassed many Hollywood blockbusters in global revenue.
The story follows Tanjiro Kamado, a kind hearted boy who becomes a demon slayer after his family is slaughtered by Muzan Kibutsuji. His goal is twofold avenge his family and find a cure for his demon transformed sister, Nezuko.
Renowned for its breathtaking animation, especially during sword fights, Demon Slayer continues to set the gold standard for visual spectacle. Combined with memorable villains, refined character designs, and beautifully stylized combat techniques, the series remains a blueprint for modern fantasy action anime.
4. Solo Leveling
Although it debuted in 2024, Solo Leveling showed no signs of slowing down in 2025. Season 2, Solo Leveling Arise From the Shadow, delivered exactly what fans hoped for and more.
In a world plagued by mysterious dungeons filled with monsters, Hunters are tasked with keeping humanity safe. Sung Jin Woo begins as the weakest of them all, barely surviving each mission. Everything changes when he gains access to a secret system that allows him to level up endlessly.
Jin Woo’s meteoric rise in power, paired with fluid animation and jaw dropping battles, made Solo Leveling one of the most talked about action anime of the year. By 2025, it had firmly established itself as a defining title of the decade.
5. My Hero Academia
Claiming the top spot is My Hero Academia, a series that has accompanied fans for nearly a decade. In 2025, the story reached its conclusion, with the final season expected to wrap up in December, marking the end of an era.
Set in a world where most people are born with superpowers known as Quirks, the series follows Izuku Midoriya, a Quirkless boy who still dreams of becoming a hero. His life changes when All Might, the world’s greatest hero, passes his power on to him. Enrolling at U.A. High School, Midoriya begins a journey filled with growth, sacrifice, and hard earned heroism.
With its unforgettable cast, grounded exploration of what it truly means to be a hero, and consistently high quality action, My Hero Academia earned its place as one of 2025’s most impactful anime and a fitting champion for this list.
