Sensei Wu is the ninja’s teacher. He is a wise old master with a long beard. Most of the stories in Ninjago, come from Master Wu’s past. He and his brother Garmadon faced evil together until his brother Garmadon eventually turned evil.

 The Garmadon family is ancient and is full of stories. You see, Wu and Garmadon were the sons of the first spinjitzu master, AKA the creator of Ninjago. Spinjitzu is the act of spinning around with your elemental power really fast, so it creates a tornado shape. Some elemental powers are

lightning, earth, ice, fire, and energy. The purpose is to attack multiple enemies at once. Then Garmadon had a son named Lloyd, who is the destined green ninja who will live up to the legacy of the first spinjitzu master. This is also why Lloyd is the main ninja.

 Since Garmadon turned evil because he was bitten by a snake, he was banished to the cursed realm. Ever since then, Master Wu took care of Lloyd and recruited a team of Ninja who had elemental powers.

Master Wu had a lot of enemies in the past. Eventually the Ninja had to fight them because of his mistakes. Here are some villains they had to face becaus

e of Wu: Garmadon, Morro, Master Chen, Krux and Acronix, and fire snakes. Through these challenges, they learned a lot of lessons, for example one lesson would be not to mess with time, since that can create more problems.

Last but not least, I think Sensei Wu is a very important character in Ninjago, and without him most seasons would not exist.
