Pen Chi

Pen Chi (Ninja スプーンでメインギャグ) was the Sensei of the Ninjas, and has been cited as the greatest Ninja master of all time. After being caught in a yellow snow scandal, he retreated to a hidden base. His current whereabouts are unknown.

Background
Pen Chi was once the greatest Ninja Master of all time.

Once, a long, long time ago, he was a little penguin named Penji.

Penji was always teased by other penguins because of his silly name. "HAHA FENJI PENJI" they called him.

One day, while Penji was hiding from the bullies, he came across an old penguin. The old penguin looked at him and said:

"You will be the greatest ninja the world has ever known. And I will train you".

Penji, a bit freaked out by this, replied, "I will house you but you must train me."

This agreement was made and the old penguin moved into his large house that seemed like a big gym-like area, which the old penguin called a "dojo". There the old penguin taught Penji the ways of Ninja. After Penji had earned his fifth black-belt and was a world-renown ninja, the old penguin "died". Just before the old penguin did, he whispered to Penji.

"I have taught you well young one. Continue your training on your own. But before I leave to join other ninja masters, you have earned a new name. Pen Chi. Use it well, for Penji is no more" and with that, the old penguin died. Only an hour later, an avalanche destroyed Pen Chi's dojo. Pen Chi, desperate after this became bitter with grief. Pen Chi trained an army of Ninjas, because he hoped that if he conquered the world with ninjas, the old penguin would come back.

Pen Chi resorted to the "healing magic" of yellow snow... something completely made up by himself. He befriended a persecuted crab because of his ability to... "gather" yellow snow. Also, the persecution reminded Pen Chi of himself as a chick.

After the great scandal was released, Pen Chi hid in an unknown location along with his secret ninja army, which is growing larger every day.

Involvement
Pen Chi is a great Ninja master, he has taught almost every ninja of the current age.

Mary Sue
Many have Considered Pen Chi a Mary sue for not being able to ever be captured by Penguins. Many still will try to anyways, including the Hochstadt Gang, in The Mystery of Pen Chi.
