Yin-Yang is an amalgamation of two characters: Yin and Yang. The two halves have vastly different personalities that contradict each other. They share one body and are in constant disputes, even over simple tasks. Yin is good-hearted, kind, honorable, and rational, whose intent is to balance out Yang, who is massively chaotic, malicious, loud and impulsive. Yin and Yang are shown to be able to get along with each other, but more than often fight.
