Background :
LEGO The Blizzard Sword Masters, were apart of the Blizzard Samurai army during the "Ice Chapter" of Ninjago, Season 11: Secrets of the Forbidden Spinjitzu. They served the Ice Emperor in the Never-Realm, as a minor antagonist, alongside the Blizzard Archers and Warriors. The Blizzard Sword Masters have a chilling appearance, reflecting their creation from the energy of the Scroll of Forbidden Spinjitzu. Their bodies were entirely made of snow and ice, giving them a translucent, frozen look in the animated series and the Ninjago, Season 11: LEGO Sets. They wore dark, ice-themed armor and black conical hat, and wielded azure-colored katanas.

Appearance :
These Sword Masters have an impacting role in the Ice Chapter's conflict, enforcing the tyrannical rule of the Ice Emperor (who was actually Zane) across the Never-Realm. General Vex, the true manipulator, frequently deployed them to specifically target the Ninja and their allies, the Ice Fishers and Formlings. Their primary function involved, participating in large-scale battles, on the Great Lake village and the final confrontation at the Castle of the Forsaken Emperor. The Blizzard Sword Masters existence was tied to the scepter holding the Forbidden Spinjitzu Scroll.

Interactions :
Throughout Season 11, the Blizzard Sword Masters interacted with various characters, primarily as adversaries. Lloyd first encountered them while traveling alone, and was nearly frozen by their attack before he used his voice to trigger an avalanche to escape. Akita, a Formling capable of transforming into a Wolf, saved Lloyd from another ambush by the Blizzard Samurai and they formed an alliance. Later, Akita used her daggers to fight the Blizzard Samurai and even the Ice Emperor himself, holding her own for a brief time. Kataru, Akita's brother, oined Lloyd and Grimfax against the vast army of Blizzard Warriors and Sword Masters. The conflict ended when Zane regained his memories and destroyed the scepter that created them, causing all the Blizzard Sword Masters and Blizzard Archers to be destroyed. The human warriors (Blizzard Warriors) corrupted by the ice magic returned to their normal forms and the Never-Realm was freed from the eternal winter.
