Originally, the Blizzard Samurai were a force of samurai native to the Never-Realm who were ruled by King Grimfax. They lived in peace with their neighbors, including the Formlings, whose peaceful nature they were familiar with. When Vex, a self-exiled member of the Formling tribe, attempted to turn Grimfax against them, Greyfax saw through his lies and ordered him expelled from his castle. Unfortunately, Vex later returned in company with an amnesiac Zane, whose Scroll of Forbidden Spinjitzu enhanced powers enabled him to transform Greyfax's warriors into zombie minions.
Powerless to stop the new Ice Emperor, Grimfax submitted to Zane and Vex's rule, and his castle became the Ice Castle. Over time, as the Ice Emperor's powers grew, he gained the ability to create more Blizzard Samurai warriors from dark ice. These warriors served as shock troops to expand the Emperor's rule-and Vex's wicked agenda-with Grimfax often serving as a field commander. This continued until Zane's comrades, the Ninja, arrived from Ninjago in search of their missing friend.
At Vex's urging, Zane sent the Blizzard Samurai to attack the village where the Ninja were staying, only for many of the ice constructs to be shattered. Grimfax led the remainder back to the Ice Castle, and were informed of the failure of their assault. Other Blizzard Samurai later attacked Lloyd on his way to the Ice Castle, while others brought the captured Green Ninja before the Ice Emperor. Grimfax later released Lloyd and Kitaru, a Formling prisoner, and led them against Vex only to run into the general and a force of Blizzard Samurai guards.
While this was going on, Kitaru's sister Akita infiltrated the Ice Castle and defeated another set of guards in order to attack the Ice Emperor. All four attackers were eventually subdued, and Vex prepared to kill Lloyd. However, his ranting awakened Zane's memories, and the Master of Ice reversed the effects of his powers, freeing the human Blizzard Samurai from their mindless servitude. Grimfax was restored to his throne, and a now powerless Vex was exiled into the wilderness of the Never-Realm.
