Shurikens of Ice

The Shurikens of Ice are one of the four Golden Weapons of Ninjago.

Powers
The Shurikens are able to freeze anything on contact. The also form Zane's Ski cycle.

Appearance
The Shurikens are triangular in shape, with a spike at each of the three points.

History
The Shurikens were first used by The First Master of Spinjitzu along with the other three Golden Weapons to create Ninjago.

Garmadon's Betrayal
When the first Master died, he entrused 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.

Found by the Ninjas
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 ninjas, as they were suspended from the ceiling. They then used a frozen Zane as a sled to escape the Ice Dragon gaurdian.

Stolen and used by Samukai
Later, in Forest of Tranquility, the ninjas 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. However, their power was 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 Garmadon may have.

In Skeleton Hands... Again
Much later, Nuckal and Kruncha got the great idea to steal the four weapons and become Spinjitzu masters through them. However, after the Sword of Fire and The Nunchucks of Lightning took them on a wild ride through the Monastery of Spinjitzu's training course, they decided it wasn't such a good idea, and returned the four weapons.
