West serves as the new central protagonist in the sequel series *Denkō Chō Tokkyū Hikarian* (*Ultra Radiant Express Hikarian*), succeeding the original lead Nozomi. He originates from the 500 Series Kodama bullet train, transforming into a robotic defender of Earth with a streamlined design featuring dominant white and blue coloring. Contrasting his predecessor’s cheerful impulsiveness, West exhibits a disciplined, serious demeanor focused on precision and efficiency during combat. His primary human ally is Kenta Hijiribashi; together they oppose the alien Blatcher gang’s destructive schemes, including the darkness-spreading "Operation Darkness." West employs energy-based attacks and defensive techniques in battle, utilizing specialized equipment such as the defensive "Lightning Barrier" and offensive "Electro Sword."
