The Four Silver Fangblades are silver daggers with ornate designs around the base of the blade and a round gem set at the end of the hilt.
- Blue Fangblade (Mega Monster Amusement Park)
- Green Fangblade (Unknown)
- Red Fangblade (Fire Temple)
- Silver Fangblade (Desert Pyramid)
- The gems and blades glow with a colored aura—green, red, blue, and grey—corresponding to the colors of the four main Serpentine tribes. However, in the sets, the Constrictai Fangblade has an orange hilt.
- They are needed to summon Great Devourer, which was said to consume all of Ninjago when awakened.
- The Fangblades were created from the Devourer's teeth, and are thus nearly indestructible—only the magma of Torchfire Mountain is hot enough to destroy them.
- Following the events of Great Devourer's attack, the locations of the four Fangblades are unknown.
