The Monkey King is a legendary monkey who once trapped the Demon Bull King inside a mountain.
At some point, the Monkey King fought against several demons such as the Demon Bull King, his wife Princess Iron Fan, the brothers Gold Horn Demon and Silver Horn Demon, his evil counterpart Macaque, and the Spider Queen. It is known he may have been quite violent, as he "would've leveled a whole mountain rage" to stop Macaque.
Imprisoning the Demon Bull King
500 years ago in China, the Demon Bull King arose from the Netherworld to wreak havoc on the world with his terrible power and laid waste to an unfortunate village. When it seemed that no one could stop him, the Monkey King appeared from nowhere and challenged him. Armed with his Golden Staff, the Monkey King engaged the Demon Bull King in intense combat, with the battle being nearly one-sided in the Monkey King's favor. At the climax of the fight, the Monkey King cut the top of a nearby mountain with his staff and used it to seal the Demon Bull King forever.
Afterwards, the Monkey King vanished without a trace and wasn't seen for centuries.
Five hundred years later, the Demon Bull King is freed from his prison thanks to the aid of his wife, Princess Iron Fan, his son, Red Son of the Demon Bull Family and the Bull Clones. The Demon Bull King's return attracts the attention of MK (who had acquired the Monkey King's staff) and his friends, and they set out to Flower Fruit Mountain to find the Monkey King for help.
After a run-in with Princess Iron Fan, and losing the staff to her in the fight, MK is separated from his friends but ends up at Flower Fruit Mountain. The Monkey King then encounters MK, telling him that he is fully aware that his staff was taken. Taking a liking to MK, he tells that he is perfect to be his successor, noting how he is the only one who can wield his staff. He tells MK to believe in himself before MK sets out to confront the Demon Bull King and retrieve the Gold Staff.
After MK and his allies defeat the Demon Bull Family, the Monkey King is last seen on the head of the Monkey King Warrior Mech nodding in respect and acknowledge of his newfound successor as protector of the world.
After MK failed to stop Red Son, the Monkey King meets him to see how he's doing. When MK asked for his help, the Monkey King interrupts, saying that it's no longer his job to fight off bad guys. Although, the Monkey King says that MK needs self-confidence by practicing more, as it took him centuries of training and fighting off demons to do so. When MK says that the city and his friends are counting on him, the Monkey King says that he's able help by limiting MK's powers, but at the cost of him losing his invincibility. MK agrees and the Monkey King limits the former's powers.
Moments later, the Monkey King takes MK back to the Weather Station.
As depicted in the legend in LEGO Monkie Kid, the Monkey King is a confident individual, especially in battle. He doesn't shy away from a challenge, regardless of the opponent's size or strength, as seen when he showed no fear in his fight against the Demon Bull King. When he encounters MK at Flower Fruit Mountain, he tells him that the Demon Bull King isn't an actual threat, as he stated that defeating the Demon Bull King would be considered a trial that MK can handle.
Since his retirement upon passing his Golden Staff to MK, The Monkey King has become somewhat lazy, often sitting around Flower Fruit Mountain eating. He doesn't step in fighting demons unless he is giving advice, or it concerns MK's well being. Despite his laziness, the Monkey Kings makes time to train MK.
The Monkey King is an anthropomorphic monkey relatively the size of an average human teenager with brown fur covering his body and tail, and peach fur for his torso, and peach skin for his face, ears, hands, and feet. The fur on his head is slicked back, tied in red ribbons. He has pastel maroon shading across his yellow eyes and thick black eyebrows.
His clothing consists of golden armor for his chest and shoulders, and yellow shirt behind a red, blue, and yellow gi with black and gold decorates for his sash and boots, and two red scarves at the back.
