I found it.

Reshiram represents the concept of  yang and controls Fire, Zekrom represents the concept of  yin and controls Thunder, and Kyurem represents the concept of wuji (the  absence of yin and yang) and controls Ice; in its alternate forms it can also control Reshiram's fire and Zekrom's thunder to some extent.

Hades, Ingrid, and Zeus ^^^^. Ok ok... that probably is nonsense, but....

I will read about it.
