|“He will send his samurai! They feel nothing, they fear nothing, they will come for you!”|
|— Sorla's warning to the Ninja in "The Never-Realm"|
Before, Zane's Takeover, some of them were a group of warriors that had ruled over the realm under the leadership of their king, Grimfax, one day Vex came seeking to become a royal advisor and wanted to crush the Formlings for revenge. However, Grimfax saw through his lies and sent him away because he did not want to cause trouble to the Formlings.
Shortly afterward, Zane arrived and lost his memories due to the actions of Vex. Vex tricked him into believing he was the realm's former leader and told him, he was his loyal advisor and that he should depose the king. Zane than deposed Grimfax and corrupted the warriors causing them to become inhuman Blizzard Warriors and created Boreal, a Dragon made of ice, to extend his power. He also created Blizzard Archers and Blizzard Sword Masters that aided Grimfax.
For around 60 years, the Blizzard Samurai ruled over the realm and Boreal froze the Village of the Formlings. They even committed genocide against a tribe of Yetis. eventually the Ninja arrived and defended Great Lake from them. However, Boreal eventually defeated them by freezing the villagers of the Great Lake. The Blizzard Samurai captured Lloyd and took him to the Castle of Ice where he found out the truth about Zane. They threw him into prison with Kataru where the two became friends and allied with Grimfax to awaken Zane.
The Blizzard Samurai fought against Grimfax and Kataru and won. However, Vex said the word "protect," which caused Zane to get his memories back, and he smashed his scepter, freeing everyone Boreal froze. Now that Zane is no longer the Ice Emperor, the Blizzard Warriors had returned to their human forms and serve Grimfax once again while the Sword Masters and Archers were either destroyed in battle or destroyed shortly afterward when Zane destroyed his scepter.
Zane briefly saw himself as the Ice Emperor on his throne during his dream.
Later, with the help of the memory loss Nindroid, Vex usurped Grimfax. Zane used the Scroll of Forbidden Spinjitzu to corrupt the soldiers and forced Grimfax into submission. Now proclaimed as the Ice Emperor, Zane became the new ruler of the Never-Realm.
The Last of the Formlings (Flashback)
The Blizzard Samurai attacked Great Lake, forcing the Ninja had to fight them. During the battle, the Ninja learned some members are corrupted humans while some are made of Ice. Grimfax destroyed the Hearth Fire and retreated with the remainder of the samurai.
All the Ninja except Lloyd stayed in Great Lake to help the Ice Fishers. Lloyd sneak through the mountains before being ambushed by the Blizzard Samurai. Lloyd is nearly frozen twice before shouting; causing the snow to fall on the Blizzard Samurai, and giving Lloyd a chance to escape. Meanwhile, Vex tries to get Kataru to join the Blizzard Samurai, but the prisoner refuses by throwing food at Vex.
The Samurai returns from their battle. Grimfax claims it was a success, but Vex shows him his crystal and states the Hearth Fire is still burning. He was surprised but agreed to make up for it.
After Lloyd was defeated by Boreal, Vex had the Samurai bring the Ninja before the Ice Emperor. Lloyd discovered that the villain was actually his friend, Zane, who was corrupted.
While Lloyd was questioning Zane, the Samurai blocked him from proceeding forward too far. Eventually, Vex commanded them to seize Lloyd, but Lloyd knocked them both and Grimfax out. After Zane blasted Lloyd unconscious, Vex commanded them to take him to the dungeon, leaving him upset and Grimfax in thought.
When Lloyd wakes up, he finds himself in prison where Vex mocks his hope and reminds him of Kataru's supposed permanent imprisonment. However, after Vex leaves the dungeon, Grimfax sneaks in and frees Lloyd and Kataru. Subsequently, Lloyd starts up a new Resistance.
The warriors guard the castle but were unaware Lloyd, Kataru, Grimfax, and Akita are sneaking around.
Later, the Warriors and Sword Masters sided with Vex and have the Resistance surrounded. Kataru and Grimfax fight the army while Lloyd tries to find Zane.
After Zane regained his memories, he destroyed his scepter, which caused Grimfax the Blizzard Warriors to return to their normal forms along with the freedom of the Never-Realm while the Blizzard Sword Masters and Archers were destroyed.
With the Ice Emperor gone, Grimfax took back power as King of the Never-Realm and consulting with the Formlings banished Vex to the outskirts of the realm. Several warriors accompanied Akita and Kataru to take Vex away.
