Master Monk Guan

Master Monk Guan was an ally of the Xiaolin Monks and was once best friends with Grand Master Dashi and Chase Young.

Personality
Guan was generally a mild-mannered mentor figure and a very kind, thoughtful and considerate person.

Physical Appearance
Master Monk Guan was a tall, muscular, but good-looking man with a bald head, his eyes were always closed with a rectangle-shaped face. Despite being the same age as Chase Young, he does not appear to have aged in fifteen hundred years.

Background
Master Monk Guan was a legendary Tai Chi master who had traveled the world dozens of times, and had defeated many opponents using only his famous Spear of Guan.

Season Two
He took Dojo Kanojo Cho to the lair of Chase Young, the greatest Heylin Warrior of all time, in exchange for the Spear. When questioned by the Xiaolin Dragons, Guan explained how he lost his Spear of Guan, and his confidence, to Chase Young. He had come to depend on the spear to the degree where he felt he was powerless without it. Omi looked up to him, and he showed them the way to Chase Young's palace so they could save Dojo. When the Dragons were at Chase's mercy, Guan appears to challenge Chase to an old-fashioned Showdown. Despite Chase's trick arena and the power of his true form, Guan was able to defeat him using the powerful Repel the Beast technique. Afterwards, Guan gave Omi the Spear of Guan, saying that he will no longer need it, and departs.

Season Three
In a later episode, the young monks are sent to him for combat training to fight against Hannibal Roy Bean. Guan was incredibly tough to them, and bullies Raimundo Pedrosa into leaving the temple, where Raimundo then allies himself with Hannibal Bean. After Raimundo blowed the Xiaolin Showdown against Omi and double-crosses Hannibal Bean, Guan revealed that he staged his entire feud with Raimundo to trick Bean. He then gave Raimundo the Spear of Guan #384 as a reward for his acting, and reveals a large building filled with numbered Spears of Guan.

In "Time After Time: Part 2" when Omi stopped Hannibal Bean from turning Chase Young to evil, Hannibal turned Guan evil instead, giving him a monster form that resembles a scorpion-like insect or even a crustacean. Also, the beads on his kimono had become skulls. As he assisted Grand Master Dashi in banishing Wuya into the Puzzle Box, he is over 1500 years old. However, there is no explanation given in the series for how this is possible, as he did not drink the Lao Mang Long soup like Chase. In their younger days before Hannibal Bean's influence, Guan was close friends with Chase Young, and though he was a Xiaolin warrior then.
