The Guardian of the Shattersoul sword (or simply The Guardian) is one of the antagonists of the show. He is the one that protects all the swords, and must be defeated before the acquisition of the Shattersoul sword. He is over 100,000 years old. Though he is indeed very evil, he has a soft spot for snow globes, which he affectionately deems "snowflake prisons".
He wields a large blue hammer, and is highly proficient in combat.
