Golden Weapons

The Four Golden Weapons of Spinjitzu, consisting of the Sword of Fire, Nunchucks of Lightning, Shurikens of Ice, and Scythe of Quakes, were a set of powerful weapons created by the First Spinjitzu Master. They were usually handled by the Ninja on their quests before being stolen by Lord Garmadon after The Great Devourer was destroyed. When forged together, the four Golden Weapons became the Mega Weapon, which comprised of the four main elements along with Creation.

After the Mega Weapon was destroyed, the remains of the Golden Weapons wound up on comet known as Delta V. The Overlord sent the Nindroids there to retrieve the remains, which would allow him to become the all-powerful Golden Master. Despite efforts by the Ninja to stop them, the remains of the weapons were obtained and melted down into the Golden Armor. After Zane sacrificed his life destroying the Golden Master, the Golden Armor was hidden away by Cyrus Borg.

History
At an unknown point in time, the First Spinjitzu Master forged the Golden Weapons at the Golden Peaks. After imbuing them with power at the Temple of Light, he used them to create Ninjago. Prior to his death, he entrusted his sons, Wu and Garmadon, with protecting the Golden Weapons.

Ghost Story (Flashback)
While training Morro, Wu eventually presented the Golden Weapons to his apprentice to see if he would become the Green Ninja. However, the Weapons didn't react, enraging Morro over his destiny of the Green Ninja being false.

Battle Between Brothers
After succumbing to the power of The Great Devourer, Garmadon attempted to claim the Golden Weapons for himself. After he and Wu clashed over the Weapons, they eventually slammed them together, resulting in an explosion that separated the two and created a storm above.

Following Garmadon's banishment, Wu proceeded to hide the Golden Weapons across Ninjago, tasking the Dragons with protecting them. After the Weapons were hidden, Master Wu created a map so that if he died or was captured, the Weapons could be obtained if they were needed. This map was given to Kai and Nya's Father, the Elemental Master of Fire.

King of Shadows
Later, the Four Weapons were gathered by Master Wu and his four Ninja proteges, Kai, Cole, Jay, and Zane. However, they were ambushed by Samukai and his Skulkin army, who stole three of the four Weapons and brought them to the Underworld. In an attempt to retrieve the Weapons, Master Wu set out for the Underworld himself, carrying the Sword of Fire.

Weapons of Destiny
In the Underworld, Master Wu and Samukai fought over the Golden Weapons before Lord Garmadon himself. Samukai eventually gained the upper hand and claimed the Sword of Fire; after that, he attempted to use the Golden Weapons to defeat Lord Garmadon and retake the Underworld. However, the Weapons' power was too great for him to handle, and as a result, he was destroyed and created a portal. Garmadon used this opportunity to escape to a secret dimension of his own, vowing to become strong enough to wield all Four Weapons at once. After Garmadon left through the portal, the four Ninja took the Weapons, vowing to protect Ninjago and be ready for Garmadon's return.

The New Masters of Spinjitzu
Kruncha and Nuckal got the idea to steal the Four Weapons from the Ninja while they were sleeping and temporarily became the new Masters of Spinjitzu through them. After a whirlwind adventure on the training course at the Monastery of Spinjitzu, the Skulkin Generals decided that it wasn't a great idea to begin with and returned the Weapons.

Snakebit
The Ninja continued to use the Golden Weapons as the Serpentine were unleashed on Ninjago through the machinations of Lloyd Garmadon. During their battle with the Fangpyre tribe, the Ninja discovered that they could transform the Golden Weapons into vehicles, allowing them to steal the Fangpyre Staff and use its antivenom to cure Ed and Edna of the Fangpyre Bite.

Day of The Great Devourer
When The Great Devourer attacked Ninjago City, Lord Garmadon returned—now with four arms thanks to his time in the realm of darkness—and demanded that the Ninja give him the Golden Weapons, as only their combined power could destroy the Devourer. Seeing the logic in their foe's plan, the Ninja reluctantly complied, and Garmadon used them to destroy the Great Devourer once and for all. Unfortunately, Garmadon promptly fled the scene with the Golden Weapons.

Darkness Shall Rise
Lord Garmadon used the combined power of the Golden Weapons to repair the Destiny's Bounty as a dark counterpart known as The Black Bounty. Using his new airship, he brought the weapons back to the Golden Peaks, where they were merged into the Mega Weapon.

Wrong Place, Wrong Time
When Lord Garmadon attempted to change the future by going back in time, the Ninja ended up shadowing their past selves on their quest to claim the Golden Weapons. When they clashed against Lord Garmadon (now allied with his past self) inside the Fire Temple, Jay gathered the Golden Weapons of the past and gave them to his friends. Using the combined elemental power of the past Weapons, the Ninja destroyed the Mega Weapon, taking the Golden Weapons with it.

Codename: Arcturus
As the Nindroid conflict raged on, the Golden Weapons were revealed to have survived the destruction of the Mega Weapon; they had been shot into space and landed on a comet called Delta V. Pythor intended to have the Nindroids travel to Arcturus to seize their remains so he could fulfill an ancient prophecy.

The Nindroids constructed a rocket ship to go into space and retrieve the weapons from the comet, with the Ninja pursuing them across Arcturus before Cryptor and his remaining allies abandoned them there.

The Titanium Ninja
With the Golden Weapons obtained, the Nindroids melted down their remains to build the Golden Armor, which endowed the power of the First Spinjitzu Master to a single being. As Pythor planned, the power was passed onto The Overlord, making him the Golden Master and fulfilling a devastating prophecy. The rest of the Weapons' remains were used to help construct the Overlord's new mech.

After the Golden Master's destruction, Cyrus Borg retrieved the Golden Armor and had it hidden away where no one would find it.

Trivia

 * The four Golden Weapons have small stones the color of their element (for eyes of a dragon design on each).

 * The Nunchucks of Lightning have dark blue ones.
 * The Scythe of Quakes has brown/grey ones.
 * If all four Golden Weapons are placed in front of the one destined to be the Green Ninja, they will react with green energy.
 * It seems that the Golden Weapons' power was transferred to Lloyd when he became the Green Ninja; when the Ninja attempt to teach Lloyd at Dareth's dojo, Lloyd punches a stack of wood with great power, causing Cole to declare "That was the power of the Scythe of Quakes!"
 * In Codename: Arcturus and The Void, the Golden Weapons are revealed to have been melted together during their flight to Delta V. If you look closely, you can see some of the weapons still have their exact shape and look (e.g. Nunchucks of Lightning and Sword of Fire)
 * Their design was reused for the Obsidian Weapons, although the Shurikens of Ice were replaced by sais as Zane's weapon.
 * When the Golden Weapons are laid out before Morro, the Sword of Fire has been replaced by a normal Golden Katana.

 * Lloyd and Nya are the only two Ninjas that do not have their own Golden Weapons.
 * In set form, the Sword of Fire has the most accurate design to its TV series counterpart.
 * In some sets, there are hints at possible Golden Weapons for different elements:
 * In Final Flight of Destiny's Bounty, Nya has a golden Sai that could've possibly been the golden weapon of Water.
 * In the Green Ninja Spinner set, there is a golden double-bladed Scythe the could've been the Golden Weapon of Energy.
 * Also, the ZX Ninja suits appeared to have Golden Weapons that are also unofficial.
