You have to feel it in your diaphragm.

—The Grand Master, regarding Davey's failure at passing gas

The Grand Master is the deuteragonist of Davey the Ninja, in which he is Davey Wilson's friend and mentor, as well as teacher of ninjutsu.


The Grand Master is gentle but firm in his teaching methods. Not much is known about him other than this, which is plain from the movie.


The Grand Master has dirty blonde hair, blue eyes, and a small black mustache. He always wears a red and black plaid flannel shirt and a long black cape.


Not much is known about the Grand Master's past, other than he has been a resident of Ninja City for quite some time, and that he trained the legendary warrior Cobra-Kai.
