Queen Berry debuts in Season 1, Episode 2 of the anime series as a rookie contestant in the same race as Special Week. She possesses a tough, rude personality and demonstrates a willingness to win through unsportsmanlike conduct, including deliberately kicking dirt at Special Week to disrupt her and attempting to physically knock her over during the final stretch. Her competitive drive prioritizes victory above fair play. Queen Berry exhibits exceptional physical power. Visually, she has silver hair, gray eyes, and wears an eyepatch over her left eye. While her official height remains unspecified, artistic depictions consistently portray her as somewhat taller than Special Week. Her character design and Japanese name potentially draw inspiration from the term "Green Beret." Her narrative presence centers entirely on this debut race. She leads in the final stretch, engaging Special Week in a direct, neck-and-neck duel, but suffers defeat at the finish line. Following the race, she participates alongside Special Week and Bamboo Memory in the mandatory winners' concert. Queen Berry's presence or development in subsequent seasons, movies, OVAs, spin-offs, or other official media beyond this single episode is not documented. Fan speculation proposes her character concept might reference multiple real-life horses that competed against Special Week's namesake in historical newcomer races.
