|“A little eavesdropper has fallen into our mitts. It seems a waste to crush something so insignificant as my first act as ruler of this new world, but so be it.”|
|— The Demon Bull King|
The Demon Bull King (D.B.K. for short) is the scourge of the Netherworld and the arch-enemy of the Monkey King. After being imprisoned for half a millennia, he plans to take over the City with the help of the Demon Bull Family and the Bull Clones.
After being locked up for five hundred years, Demon Bull King (D.B.K. for short) is back with a vengeance. Now half flesh, half-machine, he's got a grudge against the world and renewed powers to destroy it.
After leaving the Netherworld, the Demon Bull King attacked a village and destroyed everything in his path. However, when the Monkey King appeared, the Demon Bull King engaged in a battle with him, but only to be defeated and imprisoned in a mountain.
Five hundred years later, after the Demon Bull King was freed by Red Son, he questions Princess Iron Fan on how she freed him, but only for Red Son to interrupt by stating that he was the one who freed him. Although, when MK accidentally fell of Red Son, the Demon Bull King decided to kill him as his first as ruler of the living world but was stopped by Red Son, who wanted to kill MK to show the Demon Bull King how powerful he became during the past five hundred years. After MK escaped with the Golden Staff, the Demon Bull King swore to kill MK for ruining his plans until he decided to Red Son go after him instead.
Later at the Flaming Foundry, Red Son builds the Demon Bull King a special type of armor and explains its purpose to him. However, when Red Son mentioned the Golden Staff, the Demon Bull King gets mad him until Princess Iron Fan told him not to. Soon, the Demon Bull King and Red Son went off to find rare items to absorb for the former.
At a Shoe Store the Demon Bull King and Red Son asked an assistant for the latest shoes until they were ordered to go to the back of the line. Angered, the Demon Bull King attacked the Shoe Store by absorbing most of the shoes.
The next day, the Demon Bull King continued to absorb more items until he was given the Golden Staff by Princess Iron Fan, which strengthens the Demon Bull King.
As the Demon Bull King continued to take over the city, he notices MK and engages in a battle with him. However, when MK was able to go inside the Demon Bull King's armor and get the Golden Staff, the Demon Bull King was overpowered until he knocked MK against a building after the latter attempted to imprisoned him. As the Demon Bull King told MK that he isn't the Monkey King just because he has Monkey King's staff, MK creates the Monkey King Warrior Mech to defeat the Demon Bull King. However, he and Red Son were rescued by Princess Iron at the last minute.
In his original form, Demon Bull King is a muscular, yellow eyed, purple/grayish fur-colored anthropomorphic ox who wears gray/silver colored armor and a cape.
