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.
