Guardian

The Guardian is guardian of Domino castle. His first and only appearance is in "Winx Club."

Appearance
He is a disembodied head made entirely of ice. He is composed of a mouth, ears, eyes, nose, and a headpiece.

Winx Club
The Guardian first introduces himself to Bloom on her quest to find the remaining Dragon's Flame in Domino castle. He is shocked to find the heir to the throne of Domino among him upon meeting her, as he has assumingly been waiting for her to come along. He informs Bloom that in order to cross over the entrance, she must light the crystals atop the statues to make the bridge appear.

After Bloom had done so, the Guardian informs her that the spirits of Domino's people that were killed in the Ancestral Witches' attack are trapped in the ice caverns. According to legend, only someone of true blood can free them. In order to free them, Bloom must solve four riddles and press the corresponding symbols linked to the symbols of the castle.

Upon Bloom solving the riddles and freeing the spirits, the Guardian is grateful to Bloom for her service, surprised that he lived to see the day someone would free the spirits. He then tells Bloom to visit the Throne Room, a place where the Dragon Flame may still lie.
