The Best Classic Action Anime of the 2000s

Anime really took off in the United States during the 2000s, and action-packed series were at the forefront of its growing popularity. These shows captivated viewers with their exciting, visually impressive fight scenes, proving that battles between characters could be both dramatically compelling and emotionally resonant.

These anime are known for their incredible action sequences and compelling, enduring stories. While many are traditional action-packed Shonen series, others come from different genres like sports or giant robots. Interestingly, sometimes the most thrilling action isn’t about physical fighting at all.

Fullmetal Alchemist is a Darker Take on a Perfect Shonen Manga

While the 2009 version of Fullmetal Alchemist is more popular, the original 2003 series is still excellent. It actually does a better job of portraying the beginning of the story compared to Brotherhood, though it eventually takes its own unique and unusual direction.

Even with some flaws in its story, the 2003 anime Fullmetal Alchemist was truly special when it first came out, and rewatching it in 2026—especially if you’ve seen Brotherhood—offers a uniquely captivating experience. While not every idea in the original series lands perfectly, its take on the Homunculi is more emotionally powerful than the version in Brotherhood. Plus, the smaller, more focused story and memorable fights, like the battle between Ed and Greed, are arguably better than anything in Brotherhood.

Hajime no Ippo is a Sports Anime as Intense as any Battle Series

Hajime no Ippo truly excels at creating compelling boxing matches. Every fight featuring Ippo and Takamura is exceptionally well-crafted, with genuine emotional weight and a clear, satisfying beginning, middle, and end. The animation further enhances these fights, offering a raw, fluid style with a classic feel.

While Hajime no Ippo sometimes falters when it’s not focused on boxing matches – largely due to the annoying character of Takamaru and jokes that haven’t aged well – the action sequences themselves are fantastic. They’re intense, realistic, and beautifully animated, and each match feels like a complete and satisfying story.

Digimon Tamers Was the First Season of the Franchise to Push Action to the Forefront

Although battles aren’t the main draw of Digimon Tamers, and the animation isn’t always polished, the series is undeniably well-made. Unlike earlier Digimon seasons that focused on fantasy adventures, Digimon Tamers combines science fiction, action, and horror, making it the most mature and darkest Digimon anime ever created, featuring complex characters and exciting fights.

Digimon Tamers is a uniquely powerful anime – both terrifying and deeply moving – that explores the potential risks of unchecked artificial intelligence. It handles complex themes skillfully, creating satisfying character development and a memorable, bittersweet conclusion. Notably, it introduced multi-episode battles to the Digimon franchise, and many fans consider the fights featuring Gallantmon and Beelzemon, or the entire team versus the D-Reaper, to be the peak of the series – a level it hasn’t reached since.

Gintama is a Flawless Combination of Action and Comedy

Though not the most widely known anime, Gintama is highly praised by almost everyone who watches it. It’s a hilarious parody of anime in general, and it also features incredible action sequences alongside its constant, laugh-out-loud comedy.

It’s surprising how well Gintama works, considering how different its parts are. It embraces its unique mix of tones, and somehow makes it all fit together. The humor doesn’t undermine the serious moments or exciting action, and even the most dramatic scenes feel natural, no matter how funny things were just before.

Black Lagoon Offers the Most Intense Gun Fights of Any Anime

Black Lagoon is one of the most intense action anime series from the 2000s. It centers around a group of charming but ruthless mercenaries who don’t hold back in their violent, fast-paced battles against equally dangerous foes, meeting force with force.

Black Lagoon is part of that wave of gritty anime from the 2000s, but it stands out from the crowd with its strong writing and ambition. While the action is exciting and well-directed, it’s the characters – especially Revy – that truly make the show compelling. Revy is a particularly memorable and well-developed female lead in the action genre.

Zatch Bell! is a Cult Classic For Fans Who Grew Up With Toonami

During the 2000s, a lot of new action-packed anime like Bleach and Naruto came out, but Zatch Bell! stood out as the best. The series centers on a tournament where 100 demon children compete, each needing a human partner to use their powers. This setup immediately makes Zatch Bell! exciting, offering unique abilities for each character and plenty of opportunities for emotional stories.

The first 50 episodes of Zatch Bell! are when the show really shines. Its slower pace allows for great character development of both Zatch and Kiyo, as well as their bond, and gives plenty of room to introduce a large and memorable supporting cast. These early episodes also tell a number of compelling, character-focused stories. While the second arc remains enjoyable and even improves upon some aspects of the original manga’s story with Sherry and Brago, the third arc unfortunately deviates significantly from the manga’s Faudo storyline. Sadly, the anime never had the chance to adapt the Clear Note arc.

Samurai Champloo is the Perfect Successor to Cowboy Bebop

Samurai Champloo is a great anime for newcomers, often considered one of the best from the 2000s. From the same director as Cowboy Bebop, it’s a brief, mostly self-contained series that quickly draws you into its unique world. You’ll quickly become invested in the main characters, appreciate its message of tolerance, and enjoy the exciting, well-animated fight scenes, all brought to life with excellent direction.

I absolutely love Samurai Champloo! It’s such a unique show – mixing old-school Edo period Japan with a really cool hip-hop vibe. It totally works, and it’s just a blast to watch. The three main characters are all great, but Mugen? He’s the real star for me. Seriously, seeing him fight and just be Mugen is endlessly entertaining – he reminds me a bit of Spike Spiegel from Cowboy Bebop in how captivating he is.

Oban Star Racers is One of the Most Unique Anime of All Time

Oban Star Racers is a unique action anime created by France and Japan. The show centers on a teenage girl who leaves boarding school to reconnect with her father, but unexpectedly finds herself competing in a high-stakes, intergalactic race. Representing Earth, she battles racers from across the universe, all while trying to save her planet and potentially bring her mother back to life.

While other anime feature sci-fi racing, Oban Star Racers stands out by really focusing on battles during the races, and the special powers each alien racer uses to compete. It also uniquely includes a strong teen romance storyline, with a compelling love triangle between Eva, Jordan, and Prince Aikka that appeals to its viewers.

Fullmetal Alchemist: Brotherhood is Still Flawless 17 Years Later

Watching Fullmetal Alchemist: Brotherhood felt like witnessing an anime at its absolute best. It really delivers on everything it promises. While the beginning felt a little rushed compared to the original manga, it quickly found its footing and became a masterclass in storytelling. The plot was brilliantly crafted, the characters were compelling and easy to care about, and the show tackled some really profound and moving themes. Plus, the action sequences were consistently amazing – a truly spectacular experience from start to finish.

While Fullmetal Alchemist: Brotherhood has some truly amazing fights – like Alphonse versus Pride, and the battles involving Kimblee, Greedling, Fu, Buccaneer, Wrath, and Scar – the series doesn’t focus on combat as much as other anime. Overall, the fights aren’t quite as strong as those in the original 2003 Fullmetal Alchemist anime, or some other shows in the genre.

Gurren Lagann Will Always Be the Ultimate Action Anime

While other action anime like Cyberpunk: Edgerunners and even Kill la Kill might be better written, Tengen Toppa Gurren Lagann perfectly captures everything fans adore about the genre. It truly embodies the spirit of action anime like no other.

Gurren Lagann is an inspiring story about the strength of the human spirit and what people can achieve. It follows a young boy who starts out timid and insecure, but grows into a truly heroic figure. The series is famous for its incredible scale – it constantly delivers jaw-dropping moments – but even the action in the earlier parts of the show is incredibly impressive.

Considering when it was made, Gurren Lagann still looks fantastic, thanks to its strong direction and unique visual style. The characters – Simon, Kamina, Kittan, Viral, and Rossiu, to name a few – are all incredibly well-developed and effectively convey the anime’s core themes.
