Golden Weapons

The four Golden Weapons of Ninjago are the most powerful weapons in the entire universe. They were created by the First Spinjitzu Master.

History
The First Master of Spinjitzu first used them to create Ninjago. After he died, his sons were to protect them, but Garmadon tried to take them for his own selfish ends. Wu defeated him and banished him to the Underworld, after which he hid all four weapons, and placed a guardian over each one. After the weapons were hidden, Wu created a map so that if he died, the weapons could be obtained if they were needed. This map was given to Kai and Nya's father. Later, the four weapons were gathered by Wu and his four ninja proteges, Kai, Cole, Jay, and Zane. However, they were ambushed by Samukai and his skeleton army, and the weapons traveled to the underworld. There, Wu and Samukai fought over them, and Samukai gained the upper hand. After that, he attempted to use all four to ursurp Lord Garmadon and retake the Underworld, but the weapons' power was too great for him to handle, and he died. Garmadon used Samukai's death to bring the weapons together, in order to create a "vortex in time and space", so he could escape to a secret dimension of his own, and become strong enough to wield all four weapons. After Garmadon left through the vortex, the four ninjas took up the weapons, vowing to protect Ninjago and be ready for Garmadon's return. Afterwards, Kruncha and Nuckal got the bright idea to steal the four weapons from the ninjas while they were sleeping and become the new masters of Spinjitzu through them. After a whirlwind adventure on the training course at the Monastery of Spinjitzu, the skeleton generals decided that it wasn't such a great idea after all, and returned the weapons. The ninjas were unaware of the entire proceedings.
