Clamp is Ramba Ral's right hand man, accompanying him during their campaign against the Trojan Horse. Clamp primarily fills a tactician's role, being the one who found the 'Trojan Horse' for them in the first place, and often plotting along with Ral and Hamon about what to do next. When Ramba's squadron eventually completely runs out of supplies, Clamp goes into battle and is shot to death while trying to infiltrate White Base.
