PlotWhile training with Monkey King, MK began to believed that he is getting nowhere with his training, claiming that he do something else other than hammering. Monkey King, however, states that he's not going to teach MK something if he doesn't need to know it. Suddenly, MK gets a call from Mei, who told him that the Smoke Monster is attacking Megapolis.
When MK returned to the city, he attempted to defeat the Smoke Monster all by himself, but failed. Moments later, MK and Mei see "Monkey King" battling the Smoke Monster and defeated it. When MK realized that "Monkey King" was actually Macaque, he asked him if he can train him, and Macaque accepted. Unbeknownst to MK, Macaque only agreed to he can lead him into a path to darkness.After MK began to train with Macaque for some time, the Monkey King began to get suspicious. Meanwhile, Macaque takes MK to where the Smoke Monster resided, claiming that he's now strong enough to defeat it. Although MK thought he couldn't do it at first, he decided to fight the Smoke Monster again after being convinced by Macaque. When he did, the Smoke Monster steals MK's powers and gave them to Macaque, revealing that it was working for him.
Before Macaque could do anymore harm to MK, Monkey King arrives and engages in a furious battle with him, but was stopped when Macaque had his shadow clone pin him down.Macaque then used the Smoke Monster as an avatar to finish off MK, but had his punch block by Monkey King. After remembering what Monkey King said about "stepping into the strike", MK uses his remaining strength to lift the Golden Staff and use it to defeat Macaque and destroy the Smoke Monster. After Macaque was defeated, Monkey King briefly gets mad at MK for going behind his back until the latter apologized, saying that he just wanted to be good like him. Later on, the two began training again, even though Monkey King was actually tricking MK to do chores.
