The Fire Dragon was placed in the Fire Temple by Master Wu to guard the Sword of Fire, one of the Four Golden Weapons of Spinjitzu. The dragon (later named “Flame” by Kai) is capable of surviving in lava and other red-hot environments and once carried Kai into the Underworld. Flame 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.
