Stormy is a witch who is the youngest of the Trix, a trio of witches. Among the three, she is the most aggressive and self-confident, always believing herself to be the strongest out of her and her sisters (later retconned in Season 8 to being close friends), Icy and Darcy. She was also a former student of Cloud Tower as she, Icy and Darcy were expelled in the episode "Cold Spell."
