Police Win operates as a dedicated member of the Hikarian Special Vehicle Squad under the Railway Police Force, transforming from a WIN350 train model fused with sleek police car design elements. Tasked with patrolling and upholding security, he employs a versatile "police trailer" outfitted with a massive robotic arm during missions. His signature declaration, "Arrest!", underscores his commitment to law enforcement, though his compassionate demeanor sometimes allows criminals to evade capture—a tendency documented in 70 consecutive incidents. After initial challenges in operational efficiency, he undergoes rigorous training under the guidance of Seven, sharpening his skills. Equipped with a Patrivolver firearm and a Police Shield, he prioritizes non-combat responsibilities despite these tools. Police Win shares an unspoken brotherly bond with Windash and Rescue Win, though their dynamic remains unexamined within the core narrative. The character’s origins, potential evolution in alternate media, and seasonal adaptations remain unspecified in existing records.
