The Earth Dragon dwelled in the Caves of Despair, placed there ages ago by Master Wu to guard the Scythe of Quakes, one of the Four Golden Weapons of Spinjitzu. The dragon (later named “Rocky” by Cole) initially fought the ninja to try to protect the weapon. He later became Cole’s mount and once carried him into the Underworld. The rocky texture of the Earth Dragon’s skin allowed it to camouflage itself as a pile of stones. Rocky 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.
