“Really, four arms? Pfft, like that's new!”
Jay, to Mr. E using the Mask of Vengeance, "The Jade Princess"

The Oni Mask of Vengeance is one of the three Oni Masks. When worn, it appears to turn the user into a master swordsman with two additional arms.


Prior to the series

At some point in time, the three Oni Masks were created in the Realm of Oni and Dragons by the Oni. They would eventually end up in the realm of Ninjago through unknown means, with the Oni Mask of Vengeance falling into the possession of Cyrus Borg, who hid the mask within a secret compartment within Borg Tower.[1]

The Mask of Deception

Members of the Sons of Garmadon, lead by Mr. E, infiltrate Borg Tower, which housed the Oni Mask of Vengeance. The Sons of Garmadon proceeded to escape the building with the mask after triggering an alarm, but they were suddenly caught in a battle with Lloyd. While the other Sons of Garmadon members were swiftly beaten, Mr. E managed to escape from Lloyd with the Oni Mask of Vengeance in tow.

The Jade Princess

As the Sons of Garmadon attack the Royal Palace in hopes of securing the Oni Mask of Deception, Mr. E locates the Oni Mask of Deception at its display case. However, he is cornered by the ninja. Unknown to the ninja, Mr. E brought along the Oni Mask of Vengeance and puts it on, where it gives Mr. E two additional arms and swords. Mr. E then fights off the ninja, eventually knocking them down after utilizing the mask's power to use Jay's Lightning against them. As Mr. E claims the Oni Mask of Deception, Kai, in a last-ditch attempt to stop him, blasts a fireball at him, which ultimately shatters the Oni Mask of Deception in his hands.

The Oni and the Dragon

Mr. E uses the Oni Mask of Vengeance to fight the ninja while trying to escape. When fighting Lloyd, the latter manages to knock the mask of Mr. E's head, undoing the effects on him. However, Mr. E manages to escape with the mask with an undercover Zane, who saved him only to gain his trust.

The Quiet One

After the Sons of Garmadon reach the crashed Destiny's Bounty within Primeval's Eye, Killow and Mr. E both put on the Oni Masks of Deception and Vengeance on, respectively, when confronting the ninja.

Game of Masks

In the midst of their standoff with the ninja after Harumi escapes the Oni Temple with the Oni Mask of Hatred, Mr. E attempts to put on the Oni Mask of Vengeance, but is stopped by Zane. When the Sea Monster appears and fights the two factions, Mr. E uses the Oni Mask of Vengeance in combat. The Sons of Garmadon soon flees the scene with all three masks while the ninja are dealing with the beast.

Dread on Arrival

The Oni Mask of Vengeance would be brought to the newly constructed Temple of Resurrection within the Royal Palace, where it would be used in the resurrection ritual with the other two masks. However, the ninja would stop the ritual before it could be complete. The Ninjago police force soon arrives, arresting the Sons of Garmadon and presumably confiscating the masks.

Prior to Hunted

At some point, the Oni Masks were later recovered by the Sons of Garmadon. The Oni Mask of Vengeance was returned back to Mr. E.


Mr. E utilizes the Oni Mask of Vengeance while confronting the leading members of the Resistance following the discovery of the ninja's survival. Before he could do any harm, he is punched by Karlof and the rest of the Resistance come to save Lloyd, Nya, Dareth, and Misako.

Season 8: Sons of Garmadon

Season 9: Hunted


  • The Mask of Vengeance is able to transform androids, as Mr. E was revealed to be a Nindroid in "Snake Jaguar." It's unknown how this works or if this is the case with the other two masks.
  • During the ritual in "Dread on Arrival," the Oni Mask of Vengeance is referred to as "Clotho-venge" by Harumi.
  • In the Season 9 intro, Ultra Violet wears this mask despite not wearing it once during the season.
  • The Oni Mask of Vengeance is the only mask that is intact; the Mask of Deception was destroyed by Skylor with the Colossus and the Mask of Hatred was destroyed by Lloyd with the Battle Wagon. Its current location is unknown, as it has not been seen since the death of Mr. E. Its current location is undisclosed.[2]
  • When asked if Garmadon would get 6 arms after using the Mask of Vengeance, Tommy Andreasen said that the power of Oni is probably already in him,[4] so it would have no special effect and he would be an Oni with an Oni Mask.[5]
