Millo is a supporting character in Pokémon the Movie: White - Victini and Zekrom, serving as a traveling companion to Ash Ketchum and Iris during their journey through the Unova region. Originally one of the three Gym Leaders of Striaton City, where he specializes in Grass-type Pokémon alongside his brothers Chili and Cress, Millo takes a break from his gym duties to explore the world and pursue his dream of becoming a top Pokémon Connoisseur. In the film, his calm and observant nature is evident as he uses his keen eye for Pokémon compatibility and behavior to help the group navigate unfamiliar situations. He is a skilled cook, often preparing meals for both his friends and their Pokémon, which proves useful when he makes macarons that later help win the trust of the Mythical Pokémon Victini. Millo’s primary motivation is to deepen his understanding of the bond between humans and Pokémon, and he approaches challenges with a patient, analytical mindset. During the events of the movie, he participates in the harvest festival tournament in Eindoak Town, where he battles with his Pansage, though he is ultimately defeated by a rival trainer. His relationship with Ash is one of mutual respect, and he shares a friendly camaraderie with Iris. Millo also shows concern for Victini’s well-being and supports Ash’s efforts to protect the ancient Pokémon from Damon’s scheme. While his role in the story is not central, he contributes by offering strategic advice, emotional support, and practical help. Notable abilities include his talent for recognizing the synergy between trainers and their Pokémon, his culinary expertise, and his competence in Grass-type battle techniques. The movie does not provide major development for his personal arc, but it reinforces his dedication to friendship and his thoughtful, helpful character traits.
