I hope not...

I don't think we can learn a style from EVERY single character. I think that we will only be able to learn from playable, secret and super secret characters. Other characters with small roles like "Tremor" and the "Water God" will just be for show. Maybe something like while you learn from Kira, you see Jarek flipping a knife or in Edenia, Rain is standing guard at the castle. Same with Cyrax maybe being a sentinal on guard at the Special Forces base.
