Strong Fighter Lortail (ローテール Rōtēru?) is a white-colored female robot. She aids Valsky before his final battle with Metalder in Episodes 36 and 38. For most of the series, she remains a background character, and doesn't gain her first real mission until Episode 36 when she is chosen to analyze and store all of the data of the robots' fights. It seems she has deep feelings for Valsky and plans to use the uploaded information for/on him so he can defeat Metalder. She manages to successfully transfer the data/her spirit into Valsky after taking a fatal blow from Metalder's G-Kick in Episode 38.
