Oni (鬼) are a kind of yōkai, or supernatural ogre, or trolls in Japanese folklore. They are popular characters in Japanese art, literature, and theatre.Depictions of oni vary widely but usually portray them as hideous, gigantic ogre-like creatures with sharp claws, wild hair, and two long horns growing from their heads.They are humanoid for the most part, but occasionally, they are shown with unnatural features such as odd numbers of eyes or extra fingers and toes.Their skin may be any number of colors, but red and blue are particularly common.They are often depicted wearing tiger-skin loincloths and carrying iron clubs called kanabō (金棒). This image leads to the expression "oni with an iron club" (鬼に金棒 oni-ni-kanabō), that is, to be invincible or undefeatable. It can also be used in the sense of "strong beyond strong", or having one's natural quality enhanced or supplemented by the use of some tool. In addition to this, it can mean to go overboard, or be unnecessarily strong or powerful.In more recent times, oni have lost some of their original wickedness and sometimes take on a more protective function. Men in oni costumes often lead Japanese parades to ward off any bad luck, for example. Japanese buildings sometimes include oni-faced roof tiles called onigawara (鬼瓦), which are thought to ward away bad luck, much like gargoyles in Western tradition Instinct: Smash
