Sylia Stingray is the sophisticated yet driven ringleader of the Knight Sabers, an all-female group of armoured mercenaries who are the main protagonists of the Bubblegum Crisis anime series and its sequel titles. Sylia is the daughter of Prof. Katsuhiro Stingray, the man who invented the technology behind the Boomers. When the GENOM Corporation murdered her father and usurped his work for their own ends, Sylia would grow up to dedicate herself to fighting against GENOM's corruption and exposing them to the world as the criminals they were. At age 24, Sylia had established herself as a highly successful businesswoman with her high-class lingerie shop, "Silky Doll", which is housed in her own private building of Lady's 633. This location serves as the Knight Sabers' home base.
It is unknown who originally supplied Sylia with the plans for the Knight Sabers' Hard Suits, but Sylia has made efficient use of the knowledge and technology at her disposal. Each of the suits is crafted to the role that each of her teammates play. Sylia's own Hard Suit is built for speed, equipped with wings and flight boosters and armed with retractable blades in the forearms and laser blasters in the palms. Her suit has a silver and blue colour scheme.
