I'm not entirely sure what qualifies an anime as a fighter anime, so I'm just going with any anime where there is a lot of fighting. So the anime I'm choosing is Hellsing Ultimate. It is rediculous, over the top, blood splattering, and most of all, incredibly badass. But another great point was how every character had some unique and fun twist about them, none of them felt rehashed or unoriginal. Furthermore, while the anime had really intense fight scenes, it also had scenes that were the polar opposite and were super silly and light-hearted. Having all these features together in one anime made this anime one of my all time favorites.
