|“It occurs to me that great power like this could be useful. We could use it to protect our fair city.”|
|— Vangelis about the Skull of Hazza D’ur to the Upply in "Dungeon Party!"|
The Skull of Hazza D'ur was an ancient skull that used to belong to Hazza D'ur. After he died, his bones and the skull remained in the Dungeons of Shintaro until it was found by the Lowly, who were asked to retrieve it for King Vangelis. He then used the Skull to take control of the Dungeons of Shintaro as the Skull Sorcerer. Eventually, it was destroyed by Cole using the Spinjitzu Burst.
At an unknown point in time, the skull used to belong to a sorcerer named Hazza D'ur.
During the Lowly's quest, they discover the Skull of Hazza D'ur. Korgran attempts to pick it up, but Dark Magic seeps into his body. He drops the artifact after realizing the skull is evil. He then picks it up with his axe and the Lowly head back.
When they return to Vangelis, Korgran requests to destroy it, but Vangelis cites the tremendous power they could have if they kept the skull. The Lowly insist that it must be destroyed, so Vangelis presses a button causing the Lowly to fall through a trap door.
The Skull Sorcerer uses the Skull of Hazza D'ur to revive the previously defeated Awakened Warriors and defeat the Ninja.
The two flee back to where everyone was, but the Skull Sorcerer follows, shooting beams at the Ninja. When everyone is running away, Cole takes a tunnel different from everyone else, so the Skull Sorcerer decides to follow him, but loses him.
Vangelis reveals the Skull of Hazza D'ur to Cole, Wu, and Vania and turns into the Skull Sorcerer. Wu and Cole try to attack Vangelis, but he throws the Skull of Hazza D'ur at them. The skull watches as Cole and Wu fall into a trap door and Vania going after them.
The Skull of Hazza D'ur informs Vangelis that sacrifice are necessary to succeed, and he puts the Skull of Hazza D'ur away, so the Winged Guards of Shintaro wouldn't know.
The Skull of Hazza D'ur follows the Skull Sorcerer as Grief-Bringer and the Awakened Warriors break down the Geckle Strong-Cave. After the Ninja surrendered themselves for the Munce and Geckles to be free, the Skull of Hazza D'ur laughs at the tribes and lie about their promise.
The Skull of Hazza D'ur follows Vangelis and taunts the Ninja for standing in his way. When Vangelis is fighting Cole, the Skull of Hazza D'ur shoots beams at Cole.
The Skull Sorcerer and Skull of Hazza D'ur continue to fight and mock Cole. During the fight, they gain the upper hand, and the Skull of Hazza D'ur begins using its powers to overwhelm Cole, but he unlocks the Spinjitzu Burst and destroys the skull. This in return obliterates the Awakened Warriors and Grief-Bringer as well as turning the Skull Sorcerer back into Vangelis.

- The physical LEGO Skull and the 3D render in the show have a number of noticeable differences:
- While in the show Skull of Hazza D'ur is glowing green, in the sets it is light sand green.
- It has a scar through the right eye in the show, but it doesn't have it in sets.
- On the set, it has white teeth but in the show its teeth are green.
- The Skull had a similar role in the show as the Book of Monsters in LEGO Nexo Knights.
