Amazing how quickly something can become legend, isn't it? Still, thinking about it I have to wonder just what kind of training methods Greg uses. It would certainly appear that he is qualified and able to give his students actual martial arts training, but at what point and how does the unusual stuff kick in? We know that Greg apparently has seen DBZ and Ranma 1/2, but has he taken training methods from them as well? Like say, does he have students perform endurance training while wearing 50 lb tortoise shells, or do they have to snatch chestnuts out of a fire? Would his training in accessing ki actually allow his students to do that type of thing?
As a side note, apart from their outfits Sarah and Justin look really similar in the last panel here. Oh what a difference time makes in character design.
