This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Katsura-otoko (Japanese)
Katsura otoko is a man of matchless beauty who lives on the moon. A giant katsura tree grows there too, casting a huge shadow, big enough to cover the whole surface of the moon. Katsura otoko spends his days pruning the tree; as he cuts, the tree’s shadow shrinks, and the moon appears to grow.
If one gazes long enough at a katsura otoko, he will extend his hand and beckon, calling the moon-gazer towards him. With each shake of his beckoning hand, his viewer’s lifespan shrinks. If one stares long enough at katsura otoko, he or she may drop dead right on the spot!
