Yin-Yang

Yin-Yang, labeled The Quarrel, Is A Contestant On Object Showdown.

Personality
Yin-Yang is the amalgamation of two characters, Yin and Yang. The two halves have vastly different personalities that contradict each other. Together, Yin and Yang share a body and are in constant disputes with one another, even over simple tasks, such as what direction to walk or what to drink.

Yin, the white half, is good-hearted, honorable, and rational, whose intent is to balance out Yang, who is extremely blasphemous, malicious, and immoral. While Yin is happy to participate in challenges and actively tries to help out, Yang despises participation and typically enjoys the misfortune of other characters, and will lash out and attempt to harm others, including Yin. This difference in character makes Yin-Yang's participation and handiness quite limited, sparking many enemies with others.

Appearance
Yin-Yang is a circular object split into black and white by a wave-like division. The white half, Yin, is on his lower right-hand side, while, the black half, Yang, is on his upper left-hand side. Yin-Yang's mouth is on his white half, along with Yin's black eye, as the other white eye is on Yang's black half. He has two arms and two legs, which both sides can control at their own will.
