Background :
LEGO The Omega Minifigure, is a powerful and ancient Oni Leader, sought to eliminate all Creation across the Sixteen Realms, believing in a universe of pure Destruction. He plays the main antagonist in the "Oni Trilogy" story arc, Season 10: March of the Oni, driving the plot by forcing the Ninja, to unite with Lord Garmadon, against this new threat. His arrival pushes Garmadon to confront his own nature, highlighting the Omega's critical role as a catalyst for Garmadon's character development and eventual path to redemption.

Appearance:
The Minifigure is mostly black, with some dark purple accents to represent, the Elemental Power of Destruction. He wears black armor and a black cape in the show, and he wields a staff resembling a gnarled tree branch with a purple crystal at its base, which he uses to channel his dark powers and summon other Oni. The Omega's design emphasizes his connection to destruction and darkness, effectively conveying his immense power and fearsome presence on screen.

Role :
As the Leader of the Oni, Omega commands the essence of Destruction, a force directly opposed to the Element of Creation. He expresses a ruthless and vicious personality, despising any sympathy or hope in others, viewing such emotions as weaknesses. Omega uses his immense strength and energy projection abilities to easily overpower Lloyd and Garmadon individually. His goal is total annihilation of all Creation across the Sixteen Realms, aiming to cover all existence in darkness and destroy all life forms other than his own kind.

Interactions :
The Omega primarily interacts with Lord Garmadon and Lloyd. He specifically targets Garmadon, mocking him for his internal struggle and desire to understand humans, seeing it as a weakness in a fellow Oni. The Omega fights both father and son, defeating them multiple times before their final confrontation. To stop the Omega, the Ninja Team: Kai, Cole, Jay, Zane, Lloyd, and Nya, in addition to Wu and Garmadon united their Elemental Powers to form the Tornado of Creation and defeat the threat. The bright energy causes the Omega and all other Oni to vanish, saving all the Realms and reversing the petrification of the citizens. Additionally, he briefly encounters P.I.X.A.L. as she helps Lloyd and Garmadon escape, and Faith, when she joined the Ninjas at the Monastery of Spinjitzu, to fight his army.
