Super Forms Yin and Yang

Yin the Hedgehog is the fursona of Koumorichan. He is the brother of Yang the Hedgehog(although really they're one person). He appears in Star & Luna season/book 2 which hopefully I'll make.


Yin is a very clever, arrogent, and cunning character. He is very charming and seductive. He can be heartless and maybe even merciless to others. Due to the fact that he is the element Yin, which stands for darkness, cold, and death, he isn't shy about showing it. Yin is also the female element which also means he is a womanizer(although that honestly has nothing to do with it). He gets very close to a certain female, and then rip her heart out!

  • Try not to confuse him with Yang. Remember: Yang is WHITE and Yin is BLACK, so that their markings resemble their element.
