Harpie's Pet Dragon is a powerful dragon monster associated with Mai Valentine in Yu-Gi-Oh! Duel Monsters. It serves as one of her signature cards and is often treated as a key support to her Harpie Lady strategy, gaining strength when Harpie Lady monsters are on the field. In the series, it represents Mai's aggressive, elegant dueling style and appears as a major threat in her battles, especially when she uses it to overwhelm opponents with high attack power and aerial dominance.
