Snow Storm is an Air element Skylander who debuts in Skylanders: Ancient Elements. She is one of the Elemental Guardians, and has Snow as her Ancient Element.
At the top of Mt. Snowflake, the coldest mountain peak known in Skylands, lived a snow sorceress known as Snow Storm. She was gifted with the legendary Winter Wand, which allowed her to make blizzards on the spot. The Ogre King wanted the Winter Wand for himself, and ordered his minions to climb Mt. Snowflake and retrieve it. Most of them froze before they even reached Snow Storm, but those who did reach her became frozen anyway. One day afterwards, she received a letter from Master Eon asking her to meet him. The reason was to bring Snow Storm on board as a member of the Skylanders, which she graciously accepted.
