The Dragon Armor is an item that was once worn by the First Spinjitzu Master, before he left the First Realm. It was located in Firstbourne's Nest, until it was found by the Iron Baron and Wu, and the latter now wears it.
Iron Baron took possession of the armor and commanded the Firstbourne to kill Wu. However, Wu told Iron Baron that he lied to him, the armor did not allow the First Spinjitzu Master to control the Firstbourne but the purity of his heart, something Iron Baron lacked. Wu then put on the armor and held the Dragonbone Blade, becoming the Dragon Master. He rode on the Firstbourne on his way back to Ninjago.
Wu continued to wear the armor as he and his students returned to Ninjago. When reuniting with Lloyd and Nya, the two were amazed by the armor and at Wu having aged into a teenager.
Wu used the armor and blade to fight against his brother, Garmadon, along with Lloyd. However, Garmadon incapacitates Wu by blasting him off the edge of Borg Tower, leaving only the Dragonbone Blade for Lloyd to use. However, Wu wears the armor to assist Kai, Zane, Jay, Cole, and The Resistance take down the Colossus.
