What martial art did mr. karate use in Art of Fighting I

LOL wtf is this shit? Aha wow… Is this japanese version of rick roll or party van?

Speaking of fighting style. I always found the name of terry bogard’s fighting style to be funny. It’s called hack-e-yo-coo-say-ken style. (yeah I know I spelled it wrong)

But I wonder is andy bogard also the same fighting style? Was he not teached in ninja shiranoui (spelled it wrong again) techniques?
