Since Special Katas are a series of pre-planned movements, anyone who knows a kata being performed can defend or attack against that kata better than someone who does not. 

Bonuses: A character who knows the kata being performed, but in a different style is +1 to defend (Dodge, Parry) or attack (Strike) against the performer. A character who knows the kata in the same style as the person performing it is +2 to defend (Dodge, Parry) or attack (Strike) against the performer.
