Harmonic Energy, sometimes referred to as positive energy, is an energy that is known to be wielded by certain masters within Hidden Kingdom. It is the intrinsic inverse of Chaotic Energy.
Chronologically, the first known use of Harmonic Energy was by Lin Chung, who had been sent deep into the past by the effect of chaotic energy on a twister of fire created by Sohoyot's Comet during the events of Time to Go Home. However, it is unknown when and where the use of Harmonic Energy originated.
In the modern day, Lin Chung was taught to use Harmonic Energy by his master, Tien Kwan. He subsequently used it many times during the battle against Twin Masters. It was ultimately by Harmonic Energy that Twin Masters was defeated.
Harmonic Energy can be used for an extremely varied range of purposes.
- In The Rise of Lin Chung, Tien Kwan used it to create illusions of various animals for Lin Chung to fight. Lin Chung later used it to shield himself from lava in a volcano, and also to defuse the bomb created by Twin Masters to force an eruption.
