|Shurikens of Ice|
The Shurikens of Ice were able to freeze anything on contact and shoot ice beams. They were also able to form Zane's Snowmobile when the White Ninja focused his thoughts.
When the First Spinjitzu Master died, he entrusted the weapons to his two sons, Garmadon and Wu. Garmadon wanted the power for himself, and attempted to take them. Wu defeated him, and banished him to The Underworld. Wu then hid the four weapons, including the Shurikens.
When Sensei Wu's four Ninja proteges, Kai, Cole, Jay, and Zane were looking for the weapons to keep them from Lord Garmadon, they came upon the Shurikens in the Frozen Wasteland. Zane was lifted to them by the other three Ninja, as they were suspended from the ceiling. They then used a frozen Zane as a sled to escape from the Ice Dragon guardian.
In Samukai's hands
Later, in Forest of Tranquility, the Ninja were ambushed by Samukai, who stole the three weapons they had found so far, including the Shurikens. He then took them to the Underworld to confront Sensei Wu and gain The Sword of Fire. Samukai used the Shurikens to freeze the Sword in the ground, making Wu an easy target. After he defeated Sensei Wu, Samukai picked up the sword, intending to use all four weapons to rebel and defeat Lord Garmadon in an attempt to do a treason act. However, the weapons' powers were too great for him, and he disappeared in a puff of smoke. The weapons made a vortex through time and space, which Garmadon used to escape. Zane then picked up the Shurikens to defend Ninjago from any future plans that Lord Garmadon may have.
In Defense of Ninjago
After Lord Garmadon escaped the Underworld, the four Ninja took up the weapons in order to defend Ninjago. Each Ninja took the weapon corresponding to their element, so the Shurikens were in possession of Zane. The Ice Dragon, Shard, guarded them by becoming Zane's mount and pet.
The Overlord's Ultimate Weapon
The Nindroids succeed getting the Weapons of Spinjitzu and have burnt them into the Overlord's ultimate weapon. Later, the Golden Master starts to destroy New Ninjago City with his newly formed mech—made out of the gold from the Weapons of Spinjitzu. However, the Nindroids were not the only ones to escape; the Ninja have used their Elemental Shields, and have traveled out of space. The Golden Master gets frustrated, and plans to defeat the Ninja. He now preforms his own Spinjitzu, trying to stop the Ninja from going into The Temple of Fortitude. He, however, fails. The Heroes of Ninjago put on armor to resist the Golden Power from him. He, somehow, grabs all the Ninja except Zane. The White Ninja eventually destroys him and the Overlord.
Filled with the biting power of a snowstorm, these icy throwing stars cut through the air, and chill to the bone. Master them, and this powerful Weapon of Spinjitzu will always come back to your hand.
