The ninja first encountered the Lightning Dragon in the Floating Ruins. Later named “Wisp” by Jay, the dragon was there to serve as a guardian of the Nunchucks of Lightning, one of the Four Golden Weapons of Spinjitzu. Jay rode the dragon when the ninja traveled to the Underworld. Wisp later traveled to Spirit Coves to mature into an adult dragon. All four Elemental Dragons would merge into the Ultra Dragon and return to aid the ninja.
