I don't just use anime for my fight scene inspiration though. They can be a bit of an exaggeration. Research is rarely about pulling info from just one source. I use anime because of the characters' moves, their powers and weapons.
Sword Art Online: Kirito Vs. The Gleam EyesThis was a scene I had to watch again. It was that awesome.
Bleach: Ichigo vs Aizen
You know those moments where all you can say is, that was epic. This was one of them.
Nura: Rise of the Yokai Clan: Yuki-Onna vs. YosuzumeI'mma be honest with you, I chose this fight scene because I love this character. It's also a good example of using just powers in fighting.
Yes, I am imagining an epic score playing in the background of all my fight scenes.
