Oni is a Japanese folklore creature known for its demonic appearance and terrifying features. Typically described as a large, horned ogre with sharp claws and wild hair, oni are believed to be malevolent beings that bring misfortune and chaos. In Japanese mythology, oni are often associated with punishment and revenge, and are said to dwell in the underworld. Despite their fearsome reputation, oni are also considered to possess superhuman strength and intelligence. In popular culture, oni are often depicted in traditional Japanese art, literature, and media as powerful antagonists or guardians.
