First Ninja Rc9gn

The Battle with the Tengu
According to the NinjaNomicon, he fought the Tengu, an ancient bird demon. The Tengu was too powerful to defeat until First Ninja found out its feathers were the source of its power. Infused into the Ninja Suit, the feathers gave it mysterious powers and forever linked the Ninja and the Tengu together, their strengths and weaknesses shared. After he defeated the Tengu, the First Ninja imprisoned it in a sacred stone known as the Eye of Eternity, which is also known as the Sacred Tengu Stone.

The Sorceress
In 1209, when the Sorcerer and the Sorceress teamed up to cause chaos, the First Ninja fought to stop them. He pushed the Sorceress into the portal that the two sorcerers had created while trying to hit him. This banished her to the Land of Shadows.

The Sorcerer's imprisonment
The First Ninja finally triumphed over the Sorcerer in 1213 as seen in "Randy Cunningham: 13th Century Ninja". With the help of the future ninja Randy, Howard, and his squire, Plop Plop, he sealed the Sorcerer underground with the Eye of Eternity, which he locked with the Sorcerer's Key. Because he knew that possessing the key was too dangerous, the First Ninja hid it in a mystical room that will open only once every one hundred years.

Afterwards
The First Ninja continued to act as guard over the Sorcerer's prison. He wrote down everything he learned into the NinjaNomicon, as he was prompted to by Randy. At some point, as explained in "Aplopalypse Now", the First Ninja came across one of the Sorcerer's balls in the possession of a corrupted villager. Once he defeated the monster, he gave the ball to Plop Plop and placed him as guardian over it in a hidden location. When it was time for him to learn the Ultimate Lesson, his memories were taken into the Nomicon for future ninjas, and his duty was given to the second Norrisville Ninja.

Currently, the First Ninja exists within the NinjaNomicon. He tells Randy that it's his turn to write history in "Randy Cun

Civilian
As a civilian, First Ninja has greenish-brown hair tied into a small ponytail, and brown eyes, uses a red yukata with a black shirt with a high neck, black short pants under the yukata and brownish sandals

Ninja
In the Ninja Suit, First Ninja retains his brown eyes. Instead of a full-body suit, his version of the suit is short sleeved with separate gloves, and has an additional elongated head scarf. The footwear of his suit also has six respective red streaks instead of four.

Plop Plop
Plop Plop is First Ninja's trusted squire and friend. However, he tends to scold Plop Plop for horsing around or being clumsy. With a hard heart, he left Plop Plop behind in the temple in the sewer for 800 years as revealed in "Aplopalypse Now", since he believed he could trust nobody other than his closest friend to guard the Chaos Pearl for him. Although he shakes his head upon reuniting with Plop Plop inside the Nomicon, he is finally able to be with his trusted friend after ages of separation.

Randy Cunningham
First Ninja first met his successor from the 21st Century in "Randy Cunningham: 13th Century Ninja". They had a rough beginning, due to First Ninja unable to tolerate Randy's overly upbeat attitude, and even to the point of quitting his duties. However, it was also Randy's courage and determination that prompted him to resume protecting the village, and they became good friends afterwards. Later, he appeared in the Nomicon face to face with Randy, and asked Randy to write his own history in Nomicon.

From then on, First Ninja serves as Randy's mentor inside the Nomicon. He is respected greatly by Randy, but his temper can still get on Randy's nerves.

The Sorcerer
The Sorcerer is his mortal enemy, due to having killed his brothers. He is also the reason why First Ninja had passed down the Nomicon for generations. It is unknown to their relationship status after Randy helped the Sorcerer reunite with the Peddler in "Ball's Well That Friends Well", but it can be assumed First Ninja can finally at peace for a while after the Sorcerer's demise

First Ninja is serious and grim, taking his role as the Ninja very seriously. Having spent many years fighting against the Sorcerer, he is enraged and saddened when Randy accidentally ruins his plans. He also is very insightful, often speaking in riddles like the Nomicon. While usually calm, First Ninja can also become very stressed out and frustrated, shouting at others to be quiet when he is trying to figure out a solution, and feeling upset when he thinks he or someone else messed things up.
