Y\u014Dkai range eclectically from the malevolent to the mischievous, or occasionally bring good fortune to those who encounter them. They have often animal features (such as the Kappa, which is similar to a turtle, or the Tengu which has wings), other times they can appear mostly human, some look like inanimate objects and others have no discernible shape. In some folklore, Y\u014Dkai are originally animals, or spirits infused with supernatural energy that turns them into Y\u014Dkai. Y\u014Dkai usually have a spiritual supernatural power, with shapeshifting being one of the most common."@en . . . . . . . . "Yokai Physiology"@en . . . .
