Oni

- The Touhou Project series of shoot-'em-up games has a character named Suika Ibuki, an oni with a massive gourd on her back capable of producing an endless amount of sake; legend has it that no one has seen her sober in her 700 year life. A later game in the series marked the appearance of Yuugi Hoshiguma, Suika's oni associate from a group of four incredibly powerful oni that they both belong to, called the "Four Devas of the Mountains." Yuugi, despite being as great a drinker as Suika while being just as cheerful, is even less of a lightweight than Suika, being able to enter into a fight without seeming intoxicated or even spilling any of the sake in her sake dish.

Another Oni fighter of the series is Moloch.
- In Dragon Ball and Dragon Ball Z, an Oni called King Yemma runs the Check-In Station in Other World, where he decides which souls go to Heaven and which to Hell. The Check-In Station and Hell are also staffed by many other oni, many of which hold iron clubs.
