MK is a noodle delivery boy and the successor of the monkey_king_(lego_monkie_kid). When MK learns that the demon_bull_king was freed from his imprisonment, he, along with Mei, pigsy_(lego_monkie_kid), Tang, and sandy_(lego_monkie_kid), went on a quest to give the Golden Staff back to the monkey_king_(lego_monkie_kid), in hopes that he can defeat the demon_bull_king again. However, when MK went to the Flaming Mountains with Mei and Pigsy, he was presumably killed by Princess Iron Fan. But when MK realized that he ended up in Flower Fruit Mountain, he meets Monkey King and was inspired by him to believe in himself and take the Golden Staff back. When MK returned to the city, he reunites with friends and celebrated with them after defeating the Demon Bull King, earning the title Monkie Kid.

A week later, MK continued to battle demons as well as facing difficult challenges. Although, when the Demon Bull King freed Lady Bone Demon from her tomb, MK teams up with Princess Iron Fan and Red Son to free DBK from Lady Bone Demon's control and became successful.

When the Spider Queen and the Spider-Bots started taking control of the civilians at New Year's, MK wasn't sure what to do after Monkey King got captured by her. However, when Red Son says he can find an antidote that can cure the citizens, MK and the rest of his team teamed up with him to travel to the Celestial Realm to and retrive the Celestial Artifacts.

After Monkey King left to go on vacation, MK began to wonder if the Monkey King picked the wrong successor after learning Lady Bone Demon's identity. Eventually, MK learned that the Spider Queen was being used as a pawn for Lady Bone Demon and attempted to fight her, but lost his powers as a result. However, after MK realized that Monkey King lied about going on vacation and was actually looking for a weapon that could defeat Lady Bone Demon the whole time, he and the others joined him on a quest to look for it so they can beat the Lady Bone Demon.
