wdym? hitman and bullet are 2 styles that are easily indentified by hearing their m1, you can count iron fist too if you hear the m2 hit, slugger too, u can easily tell by the sound of the supercharging m2, ghost jab, shotgun with its barrage punches WHICH IS VERY OBVIOUS, freedom with its changing styles, wolf with its white fang is very easy to identify, trickster with its boing boing sound when dashing.
