This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Kyubi-no-kitsune (Japanese)
In Japanese folklore, kitsune are foxes that possess paranormal abilities that increase as they get older and wiser. According to folklore, the kitsune-foxes can bewitch people, they have the ability to shapeshift into human or other forms, and to trick or fool human beings.
While some folktales speak of kitsune employing this ability to trick others—as foxes in folklore often do—other stories portray them as faithful guardians, friends, and lovers. The story of this nine-tailed fox is likely historically tied to Emperor Konoe's beloved courtesan Fujiwara-no Tokuko, an elegant and accomplished woman who exercised an overwhelming and wicked influence over the emperor.
