Master Monkey is the friendliest and most approachable of the Five. he is the quiet but the most fastest member of the furious five, and one of the most humorious (ironic that he does not talk much, but as of the sequil and the following TV series, he begins to talk more). Monkey assumed that Po being the dragon warrior was a joke, but later accected him due to his humor and cooking skill. Monkey was the first of the five to recognize Po's determination and is the only member of the Furious Five who refers to Po by name. He also seems to harbor the strongest sense of humor within the Five as well, responding most strongly to Po's sense of comedy, as well as the comedy of Spongebob and Friends. Unlike the others, Master Monkey uses a weapon to help him fight. He uses a staff, a traditional weapon used in Kung Fu and other martial arts. Monkey is the fun-loving brother to the louge, he makes very senario fun, even when bad guys enter the picture, but is happy to take things seriously.
Before he became a kung fu warrior, it is known in the Secrets of the Furious Five that Monkey was the village trickster when he was a teenager, often making people slip on banana peels (from bananas that he would eat) and/or pantsing them in revenge for an incident in his youth that resulted in becoming the laughingstock of a few other children in the town. The townspeople sent many powerful warriors, including rhinoceros guards from Chorh-Gom Prison, to force him out of town dead or alive, but Monkey humiliated each and every one of them (by swiping their belts off, resulting in their pants falling down). Monkey was finally subdued by Master Oogway, who, aside from wearing no pants, also used his shell to hide from Monkey's attacks. Oogway taught Monkey compassion by saving him from a falling beam, which led Monkey to develop into the warrior he is today.
