Sensei Wu used to train in a monastery with his brother, Garmadon. After Garmadon became evil, Wu recruited a team of ninjas to banish evil, and hopefully bring Garmadon back to his senses, which eventually they did. Wu is a master of spinjitzu, able to create a mini tornado just by spinning. He has great acrobats and stealth, even for his age. His staff allows him to vault off objects, and glide in the air by spinning it. He has his trusty Flying White Dragon, for long distance travel.
