Each of the Elemental Blades appears as a short golden stick detailed to look like a dragon's head (resembling one half of the Nunchucks of Lightning). A small gem is embedded in the hilt, color-coded to their wielder's element.
- Kai's Blade is orange at the tip, fades to red near the hilt and possesses a red emblem.
- Jay's Blade is blue at the tip, fades to yellow near the hilt and possesses a yellow emblem.
- Zane's Blade is white at the tip, fades to grey near the hilt and possesses a blue emblem.
- Cole's Blade is green at the tip, fades to purple near the hilt and possesses a green emblem.
When active, elemental energy bursts from the dragon's mouth and forms into a large, angular blade with a slightly jagged appearance. The slightly-fluorescent blade appears to be made of crystal, colored to resemble the Ninja's respective element. In combat, the blades are surrounded by an aura of their respective element (Fire, Lightning, Ice, or Earth).
Each Elemental Blade has elemental properties similar to the Golden Weapons:
- Kai's Elemental Blade can generate and manipulate intense heat and fire, allowing it to shoot fire blasts, ignite nearly anything, and create a defensive barrier of fire.
- Jay's Elemental Blade can manipulate lightning, generate electricity to electrocute others, and launch powerful lightning bolts.
- Zane's Elemental Blade can generate frost and ice. It can freeze someone or something in place and shoot freezing blasts.
- Cole's Elemental Blade can create earthquakes and seismic shocks. It can also create strong piles of sediment and stone.
The powers of the Elemental Blades appear to be even stronger than the Golden Weapons, as they are attuned to their wielder's natural abilities (but they also seem to be created mainly for fighting, noting that they are all blades). When combined, the Elemental Blades can also empower the Green Ninja, unlocking the abilities of the Ultimate Spinjitzu Master. They can also be used as keys in another part of the Temple of Light, unlocking the Golden Mech.
In order to combat the Stone Army, the Ninja traveled to the Temple of Light, finding an elaborate engraving on the floor with their individual elemental insignias. When Lloyd struck the Instrument of Peace Misako had spoken of—a giant bell hanging above the floor carving—a bright light shone onto him and reflected onto the crystals nearby. The lights shone onto each of the Ninja, giving them new suits and Elemental Blades.
As Lloyd became suspended in a light beam, the Ninja sent him their powers through their new weapons. Once he fell to the ground, his full powers were unlocked, giving him a new suit of his own. When the Stone Army marched into the Temple, the Ninja defeated them with ease using their new elemental powers.
The Ninja practiced their new Elemental Blades on the coast, where they blasted some coconuts.
When the Ninja returned, they used their Elemental Blades to encourage Lloyd to tell him that they were all in this together.
The Ninja returned to the Temple of Light and discovered a new chamber with four slots around the room. When the Elemental Blades were inserted into the slots, the center of the floor opened up, revealing the Golden Mech.
Following the Overlord's defeat and the reconstruction of Ninjago City, the Elemental Blades appeared to no longer be in the Ninjas' possession; Jay mentions he misses the blades when the Nindroid crisis breaks out. It's possible that Master Wu hid the blades somewhere safe since they were still intact after the Overlord's defeat.
