History
As revealed in the episode "Time to Go Home," thousands of years ago, Twin Masters was formerly a human prince named Yang Tu who desired to take over all of Hidden Kingdom. When Lin Chung was sent back in time and fought the young prince, he propels Twin Masters off of a cliff into a volcano with his harmonic energy, Unfortunately, his harmonic energy mixes with Yang Tu, transforming him into Twin Masters. After spending a millennia in the volcano, Twin Masters emerges, mastering chaotic history, and changing their plan to destroying Hidden Kingdom and ruling as a cruel despot.

In their first appearance, they task their minion High Roller with capturing Commander ApeTrully, and has High Roller take the Chameleon army with him. When they were defeated, Twin Masters fires a negative energy ball into a volcano, boasting that once it erupted, any survivors of the apocalyptic event would blame Big Green for it. Having learned the power of harmonic energy, Lin Chung seals the volcano. The episode then ends with Twin Masters stating their plans of destruction and vengeance on First Squad.

In "Big Baby Turtles," after the Zebra Brothers steal an amulet from the Owl Kingdom, Twin Masters infuses their chaotic powers into it, converting Big Breen's turtles into giant abominations and sends them to attack First Squad. Upon being thwarted, the turtles return to their original size.

Twin Masters strikes a deal with Second Squad in "Second to None," and possesses them with their chaotic energy, tasking them with exterminating First Squad. After Lin Chung succeeds at breaking the spell over Second Squad, Alpha Girl pushes Lin Chung out of the way of a chaotic blast from Twin Masters. Thankfully, she survives.

The Flying Fish army steal Mighty Ray's eyes, giving them to Twin Masters. They then use the eyes to generate a chaotic storm which would engulf all of the Hidden Kingdom. Mighty Ray is forced to overcharge himself by eating several bananas at once, causing Twin Masters to writhe in pain. Even though Mighty Ray receives his eyes, Twin Masters proclaims that it was too late for them, because the chaotic storm they created would still destroy everything. This forces Lin Chung to enter the storm and destabilize it from within much to Twin Masters' chagrin.

Another plan of Twin Masters involves tricking the Bald Eagle King and his troops into drinking enchanted tree sap which transforms them into pterodactyls and also creates a purple substance that Twin Masters intends on using to reconvert all life in Hidden Kingdom to its prehistoric state. The spell is reversed through a use of creating a gas and transmitting it through the trees.

In "Demon Heartland," Twin Masters deceives First Squad into going to an island to destroy what was believed to be their heart. Revealing that it was actually a chaotic bomb, Twin Masters seals them in the cave along with the Hermit Crab King and Sea Elephant King, explaining that their services were no longer needed. Through quick thinking, the group escapes, and the two kings join Big Green.

ApeTrully is kidnapped again in "Animals Inside," and Twin Masters possesses him with their chaotic energy and forces them to fight against First Squad. Regaining himself thanks to Lin Chung, ApeTrully blasts Twin Masters with the chaos energy they bestowed him.
