Oho! The Legendary Sensei

This is the fourth episode of the first season of The Ninja, made in 2007.

Synopsis
Dyne appears on his guard but alone in the forest. After he begins to be attacked from all sides it becomes apparent that he is facing an invisible opponent. After several unsuccessful attempts to locate his attacker, Dyne summons his ninja pole to arm himself but is immediately struck by another surprise attack and knocked out cold.

Dyne is awoken by a red haired scotsman who has apparently materialised from nowhere and introduces himself as Sensei Angus McGruff. The newcomer identifies Dyne's assailant as Clipsen and offers to train Dyne so he can out manoeuvre the invisible ninja. Dyne initially refuses out of arrogance but when McGruff easily lands a hit without Dyne being able to block it, he agrees to the training.

McGruff begins by putting Dyne through a punishing series of exercises, which Dyne is unable to complete. Giving this up as a bad job, McGruff decides to cut straight to the chase and teach Dyne a technique strong enough to best Clipsen in one blow. Explaining that the energy for the attack must be drawn from the place in the ninja's body where chakra is most concentrated, McGruff encourages Dyne to focus on his heart (unlike McGruff himself who draws the energy from his brain).

Several hours later, Dyne is still attempting to muster the energy required to perform the new technique. With McGruff watching unseen from nearby Dyne finally manages to hold enough energy within his hand to perform a concentrated attack strong enough to fell a nearby tree. Dyne seeks out McGruff to thank him for his help and McGruff in turn expresses his surprise and delight at Dyne's progress and proudly declares that the technique Dyne has just learned is named "the haggis fist". He also gives Dyne some parting gifts, including a mysterious amulet which McGruff refers to as the Kaiser Ankh. Dyne then departs, intending to seek out Clipsen for a second bout.

Trivia

 * McGruff explains that the missions Dyne has been undertaking recently have been passed to him by McGruff's cousin. It can be inferred that this cousin is the same person with whom Dyne had a brief phone call at the end of episode 3.
 * When McGruff first appears, he introduces himself word for word as follows: "I am Sensei Angus McGruff. My foe- My friends call me Angus." As The Ninja was a largely improvised show which rarely did second takes while filming, mistakes in delivery were common in the final cut and this accounts for the prior example. In this case however the wording also unintentionally adds some interesting foreshadowing for The Ninja Side B (The Ninja Season 3) in which Dyne meets the four ministers of the Sun Country who all befriended McGruff after first meeting him in deadly combat and so could be said to be both "friend" and "foe" to him.
 * Apart from the amulet, Dyne's second gift from McGruff is a set of ninja boots which are handed over with a measure of ceremony to them. These particular boots would never be worn by Dyne in any episode of the show to come.
