There has to be a better way to translate 幻獣 in this case. This is from a sentai show. It's the name of a martial art. The subs I'm watching call it "Phantom Fist".
Unfortunately, that doesn't quite cut it. It's an evolution of a martial art. Originally it was just 獣拳, "Beast Fist". The characters had styles revolving around the movements of actual animals, like a Chameleon and Lion. Now that it's 幻獣拳, it revolves around fictional animals, like Dragons and Phoenixes.
Anyone have any ideas for a decent translation?
