Descriptions highlight her exceptional raw power. Physically, she possesses silver hair and gray eyes, consistently shown wearing an eyepatch over her left eye. While her exact height is unspecified, visual depictions show she stands taller than Special Week. Her Japanese name, "Queen Bere," is subject to unofficial fan speculation suggesting a connection to "Green Beret." Within franchise lore, fan analysis also posits her character draws inspiration from multiple real-life horses that competed in the same historical debut race as Special Week's namesake.
