Master Wu

Years later, having officially become a master, Wu would develop an incredibly eccentric and mysterious personality, often instructing others with cryptic hints and would often avoid being straightforward, confusing everyone with his strange methods and ways. Wise because of his years of experience, Wu had an enormous amount of forethought and skilled intelligence, triumphing over several enemies as a result. Incredibly graceful, even when losing, Wu would be willing to sacrifice his life under any circumstances to protect others. Despite this, Master Wu also had a more silly and playful side. He enjoyed less reserved actions such as food fights, dancing, and riding on Ferris wheels. However, Wu also had a past haunted by his mistakes, echoing his own brother's wisdom, and secretly reprimanding himself for the corruption of Garmadon and Morro, and for not telling Misako about how he felt about her. One of Wu's biggest flaws is his tendency to keep secrets for himself, something that normally ends up coming back to haunt him, as seen throughout the series. This was seen in three big occasions: the first when he never told the Ninja about Morro, which resulted on the Ninja not being prepared to face him when he escaped the Cursed Realm. Having a kind heart, he brought in a homeless orphan named Morro and took care of him, discovering his fatherly instincts after taking in the Master of Wind to be his pupil. However, he also had little patience for wrongful behavior, readily disapproving Morro's reckless actions, unanimously agreeing with his brother to banish the Anacondrai generals to the Cursed Realm, and being highly protective of his father's name. As a young boy, Wu was a bit irresponsible, impulsive, impatient and a little reckless. His curiosity regarding the Serpentine had led him to break his father's rule of never venturing into Serpentine land and even convince his brother to go along with him.
