Another martial artist, Sho'nuff (also known as "The Shogun of Harlem") sees Leroy as the only obstacle to being acknowledged as the true master of martial arts. Leroy refuses to fight him and a furious Sho'nuff vows that he will defeat Leroy. Sho'nuff and his gang later break in and assault Johnny Yu, one of the students at Leroy's martial arts school, demanding that Leroy bow before Sho'nuff. Finally, Sho'nuff and his gang attempt to send a message to Leroy by destroying the Green family pizza restaurant.
