Oni Masks.png

"Tarakudo's reign came to an end when the spirits of his generals were trapped within masks; nine generals, nine masks."

The Oni Masks are a collection of masks originating from Japan, each created by ancient Good Chi Wizards to seal the spirits of Tarakudo and his nine Oni Generals within them. The masks were then scattered to the four corners of the Earth to ensure that the Oni could never again rise to power. The hunt for them serves as the primary focus of Season 4.


Oni Masks can each summon a different tribe of Shadowkhan once the mask is attached to a host's face, but if all nine masks are brought together in one location, the masks shatter into pieces and the Oni spirits are set free, summoning enough Shadowkhan to engulf the Earth in eternal darkness.

If worn too long, the masks will possess the wearer until he/she is consumed by the demon's psyche and corrupts the wearer's chi. Depending on how much of the mask is worn by the host, the Shadowkhan will only have that much of them summoned. The wearer is also granted with superhuman strength equal to usage of the Ox Talisman, and likewise equally immense agility and reflexes. . Since they are not full Oni, users are not affected by onions.

Each mask possesses the power to summon a different tribe of Shadowkhan and requires a different removal ingredient. The removal spell also requires a lizard tail, wolfsbane, sulfur root, and the left eye of a newt.

A tenth mask was forged, intended to imprison Tarakudo like the rest of his demon generals, but he got to it first and hid it in the Shadow Realm, putting it beyond the reach of any human without the use of shadow magic and the means to locate the mask.

  • Most wearers will only have their faces changed to resemble those of the Oni possessing them. However, when Paco and Scruffy wore masks, their whole bodies changed to look more demonic.
  • Finn was the only person who was completely conscious and didn't have his personality brainwashed while his Oni (Ikazuki) was controlling his body, due to their unusual situation (a Rat Talisman-animated Ikazuki mask was accidentally fused to Finn's rear end when he sat on the mask).
