The 15 Best Action Anime OVAs of All Time

OVAs, also known as Original Video Animations, are anime with one or more episodes that are directly released to the public without being released in theaters or aired on TV. Sometimes, they are extras bundled with manga or DVD releases, and sometimes they are independent projects. Some of them are even full-length series! Just like TV anime, OVAs come in every genre - including action. Let's take a look at some fantastic action anime OVAs. 

Because OVAs are often associated with offshoots of TV series that tell side stories or develop a side character, it might be surprising to learn that the best action anime OVAs include full-length series. Hellsing Ultimate, for example, is a fully realized series at 10 episodes long. Even more surprisingly, the 110-episode Legend of the Galactic Heroes technically qualifies as an OVA. But some great action OVAs do fit the pattern - Attack on Titan: No Regrets does a deep dive into the Survey Corps leader Levi's backstory.

    Attack on Titan: No Regrets

    Levi Ackerman is one of the most beloved characters in Attack on Titan, so an OVA that details his backstory is a welcome addition to the series. No Regrets opens with Levi as a young man struggling to survive in the Underground, a hellish slum from which there is seemingly no escape. Because they have so few options, Levi and his friends Isabel and Farlan spend their days committing crimes for cash. One day, they accept an assassination gig - in exchange for taking out Erwin Smith, they'll gain citizenship above ground. As they spend more time on the surface world, they learn that that may not be such a great deal after all - and Levi discovers that Erwin is someone he respects more than anyone else he's ever met in his life. 

  • Kenshin Himura was once known as the Hitokiri Battousai, a legendary assassin who took lives in order to further his political goals. Eventually, he came to realize that he no longer wishes to pursue a path of violence and instead wishes to pursue the life of a pacifist. However, he'll still fight to protect others from harm. How did a ruthless mercenary become such a gentle person? That's the question that Samurai X: Trust and Betrayal seeks to answer. It goes back to Kenshin's early childhood, depicting both the violence of his surroundings and the difficult choices he was forced to make in order to survive. This is a necessary companion to the TV anime Rurouni Kenshin.

  • Sometimes, an OVA is created that eclipses the associated TV series. That's what happened with Hellsing Ultimate, which is generally considered to be an improvement over the original Hellsing, both because of its art and animation quality, and because it accurately follows the manga that both are based on. This 10-episode OVA follows Alucard, an immortal vampire who has joined forces with the Hellsing organization to destroy his own kind. Why would he do such a thing? Because he's so completely bloodthirsty that he'll take any opportunity he can get to take lives. This is an intensely violent OVA, and it's not for the faint of heart - but if you love to be horrified, Hellsing Ultimate may be right up your alley.

    One Punch Man: Road to Hero serves as a prequel to the original series, and while it's anime-only, it was written by the manga's creator, ONE. It depicts Saitama during his training period. Thanks to his hardcore training regimen, he's constantly destroying his tracksuit, but a local tailor is kind enough to fix it for free. When his tailor starts getting hassled by a local gang and might need to close up shop, Saitama steps in to help him. If you love Saitama, you won't want to miss his early foray into heroism.
