“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[src]

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 Megapolis with the help of the Demon Bull Family and the Bull Clones. However, after Lady Bone Demon possessed the Demon Bull King, she used him to turn against Princess Iron Fan and Red Son, until MK freed the Demon Bull King from Lady Bone Demon's possession.

After the Battle of the Flaming Foundry, the Demon Bull King and Red Son took some time off from being villains and began a food stand. Despite this, when the Demon Bull King was captured by the Spider Queen at New Year's, he, along with the Monkey King and several other demons were having their powers extracted until the Demon Bull King was able to free himself and the other prisoners from the Arachnoid Base. He then teamed up with the Monkey King and MK's team to defeat the Spider Demons.
