Twin Masters was a malevolent entity who desired to bring chaos and destruction to the world. He was the master of High Roller, and was the main antagonist of season two.
Twin Masters is roughly 35-45 ft tall. His head resembles a skull with small, glowing, yellow pupils. His arms begin narrow from the shoulders and get wider until the stop at the hands, where, interestingly enough, he has small "hands" at the end of each massive finger, he has four fingers on each hand. His legs begin narrow and widen all the way to the feet where he has three toes per foot. He is split into two distinct sides hence the name "Twin Masters". On his right side he has red, everything on the right is somewhat jagged and resembles lava and fire, while on his left side he is blue with a few of his features being wavy and resembling water and ice.
In The Bronze Giant Part I he took water from the Lake of Thai Gi, and created a cocoon in which he encased himself so as to metamorphose into an even more powerful form. His skull-like head became more luminescent red and blue and was attached to a large red and blue orb with a ring of "planets" circling it. The area around his head was now black with specks of green (mimicking space and stars), his fore-arms were now black with green specks, as well. He had a dark blue and red tail in place of his legs, the tail ended in a luminescent green tip with spikes sticking out.
Twin Masters was only known throughout legends as a being of chaos and thus information about him was shrouded in mystery, until the episode "Time To Go Home". This episode revealed that Twin Masters was once a Prince called Yang Tu who desired total control of Hidden Kingdom. Because of Lin Chung's interference when he traveled back to the past, he is responsible for turning Yang Tu into Twin Masters.
In "Return of the Pterodactyls", Twin Masters commanded the eagles to drink the sap from the ancient trees of the hidden kingdom. The sap turned them into pterodactyls and gave them the ability to transform anything they attacked into prehistoric versions of themselves. Few of the animals know of him, including Sparky Black and Sparky White.
In "Time to Go Home" It was revealed that he was once Prince Yang Tu, who wanted complete and total control of the Hidden Kingdom. Lin Chung was sent 1000 years into the past to prevent Yang Tu from walking the path of evil.
Unfortunately, instead of changing Yang Tu's fate, Lin Chung became the one that caused Yang Tu to become The Twin Masters we all know, thus creating a time loop.
Twin Masters is, without a doubt, a formidable opponent. Although much of the time he makes others do the fighting for him, when he does fight, he becomes a deadly opponent. He wields the magic power of chaos and excels at the art of corrupting the natural world to do his bidding. He is able to use his incredible powers of chaos to perform all kinds of dark magic, ranging from hypnotism to creating deadly storms of doom. Twin Masters' abilities thus make him the most powerful adversary First Squad has ever faced so far in the series. This is a list of abilities Twin Masters uses during Season 2:
Unstable Volcano: As seen in the episode "The Rise of Lin Chung" he can throw a power ball into a volcano that will make the volcano spit fire everywhere.
Unstable Power Ball: He can create a unstable power ball of chaos energy that can destroy anything in one shot.
Enchanting: As seen in the episode "Big Baby Turtles", he could enchant the owl amulet to make it turn animals into monsters. This is likely also the result of chaos energy.
Hypnotism: In the episode "Second to None" he hypnotized Second Squad, showing he has the powers of hypnosis.
Chaotic Blast: in the episode "The Rise of Lin Chung" he was shown to blast High Roller which hurt him. In 'Animals Inside' Twin Masters shot ApeTrully with a chaotic blast which made him a tough opponent for First Squad.
Transformation: In 'The Bronze Giant', Twin masters used water from the Lake of Tai-Chi to make a cocoon around himself. When he emerged he had a handful of new powers, including upgraded chaotic blasts, as well as the ability to harness all the chaos in the universe. He could also create a portal through which there was only chaos.
- Twin Masters is deceased, as of "The Bronze Giant". This makes him the first enemy that was actually killed instead of just subdued!
- In "Time to Go Home", when Lin Chung went back in time to Yang Tu, it was destined to happen that he'd go wrong instead, because it had already happened. If Lin Chung hadn't gone wrong, or hadn't even gone back in time, Twin Masters wouldn't exist today. This is an example of an Ontological Paradox.
- Although not a classified hero, he bears considerable resemblance to the nickname of the sixtieth hero of the Liangshan in Water Margin, Fan Rui, whose nickname is "Demon King of Chaos." The sixtieth hero of Big Green is Fox King, however.
- He is voiced by Scott McNeil, who later voices The Overlord from Lego NinjaGo.
