Although designated with the number '5', Cinque was first activated shortly before Quattro. Her 'IS' allows her to transfer energy into any metal that she touches and transform them into explosives. This ability is typically applied in her Stinger throwing knives. The Shell Coat that she wears is a defensive device with Barrier and AMF capabilities. Very experienced due her long time of service, her small size make her well suited for infiltration missions. With her high operational and combat skills, along with her unique 'IS', Cinque co-leads the Numbers along with Uno and Tre. In spite of her stoic demeanor when executing missions, Cinque has a caring personality that earns her the adulation of her younger sisters. She is especially tender toward Nove, who shows equal concern back toward her. (Source: Wikipedia)
