The Legendary Dragon is a green, fire-breathing dragon.
The Legendary Dragon appeared at the Monastery of Spinjitzu and took Master Wu as a captive, much to the shock of his Ninja students. The six of them attempted to rescue their master from the beast, but the dragon fought and dodged them before flying through a portal. The Ninja pursued it and found themselves in a chamber of a pyramid from the Desert of Doom, where the Fire Dragon and Thunder Dragon awaited them. After briefly appearing alongside its fellows, the Legendary Dragon departed through yet another portal, with the other two dragons carrying the Ninja through after it once Cole had made his way across the chamber's lava pit.
