The Ice Dragon was the guardian of the Shurikens of Ice, one of the Four Golden Weapons of Spinjitzu. The ninja first encountered this beast in the Frozen Wastelands, where he had been placed by Master Wu to guard the shurikens. Shard later became Zane’s mount and carried him into the Underworld. Shard is the smallest of the four dragons. Shard 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.
