Kapo
In Polynesian mythology (specifically: Hawaii), Kapo is a goddess of fertility, sorcery and dark powers who can assume any shape she wills. She is the mother of Laka, although some versions have them as the same goddess. Her parents are Haumea and Kane Milohai. Kapo also had a detachable vagina, which she once used as a decoy to aid her sister Pele to flee the overzealous Kamapua'a.
Kapo also stands for Kameradenpolizei, and refers to individuals who have been recruited by an enemy to police their own people. The term was used to describe concentration camp prisoners, who were appointed to supervise other prisoners. It has since become derogatory.
