Sylia Stingray leads and finances the secret vigilante group and sometimes mercenaries known as the Knight Sabers in Mega-Tokyo, often destroying rampaging Boomers. She is the daughter of Dr. Katsuhito Stingray, the creator of the Boomers and the older sister of Mackie Stingray.
In the OVA, Sylia Stingray is the daughter of Dr. Stingray, the founder boomers, which were baiaclly robots built to do hard phsyical labor or jobs that were too stressful for the every day human. Other than reveling that, not much is known about her. Throughout the series many belived that Sylia herself may have been a Boomer or a techologically enhanced human, however this was never said in the siereis for sure, leaving most fans with the question still lingering in the their heads even today. She had one other sibling; Machey Stingray, who was the genious out of the two.
In the series it is raveled why Sylia hated Genom so much, because they were the cause of her fathers death when she was a child. With the rage that she had built up inside her she used the technology that her father left behind to create what are known as Hardsuits. They were bacally boomers, only the wearer controlled them. At first she tried to go at Genom alone, but soon felt that help was going to be needed, then got the rest of the three girls into the group and forming what is known today as The Knight Sabers. The five women would go around Tokyo and fight against Genom's secret projects that would rampage through the streets. Most of them were too powerful for the AD police to even have a fraction of a chance of stopping them.
In the original series, she is a cool, enigmatic, almost stoic demeanor, and was known mostlly for her repressed, conservative business clothing, even though she sold lingerie.
In these series, Sylia's character from being a cool, calm, conservative business woman is totally changed up for a more emotional unstable, person. While she is very pleasant and cheerful in public, she has many violent mood swings when things dont go exactly her way and wears most of the things that she sells in her shop. Almost opposites in personality in this series.
While being about 24 years old, Sylia is recognized mostly for her very long hair that is a silver white, with almost blue and purple tint, her eyes are no different which are a light bluish purple color. Much unlike the original Sylia, where she had no love life, the 2040 Sylia has a 'secrete' lover by the name of Nigel Kirkland, who is the mechanic who builds and repairs the boomers when needed. She is also shown to be of the Jealous type, as when Mackey, her brother, told her that Priss hangs much around Nigel's garage, becoming agry at this. Another person she is always seen with, but not in a lover way, is Henderson, a old and kind butler who is always seen worrying about 'Mistress Sylia's' safety. As for the other four girls she seems to get along with them just fine, and is always seen to be very straightforward with them, giving them advice to her as if they were her customers. She is seen teasing Nene the most, making her blush and stammer uncomfortably throughout the series.
Based on Dr. Katsuhito Stingray's research, the Hardsuit is a form of powered armor that bestows upon the wearer with superhuman strength by enhancing the wearer's natural strength by over 10 times and increased survivability against a wide number of threats from bullets, explosions, and nanotech attacks. It is also NBC (Nuclear, Biological, Chemical) rated.
Sylia's Hard Suit is the prototype for all of the others and boasts blue and light coloring as well as greater armor plating than any of the other Hard Suits (which also decreases her agility and speed compared to some of the others). Her main weapons upon the suit are two laser-edged swords that fold out of the forearms of the suit but she also has a pair of laser blasters built into the palms of the suit which can also be used to discharge a high-intensity blast as well as the contact detonators "knuckle bombers". In addition, what sets apart her suit the most from the others is that she has a pair of extendible flight wing veniers that grant her short range flight capabilities compared to the jump jets that enable the other Hard Suits to jump higher and slow their falls.
Sylia's Hard Suit was designed specifically for her role as the long range fighter of the Knight Sabers, supporting the hand to hand combatant (Priss) and close range fighter (Linna) of the team while she protected their electronics warfare specialist (Nene) which meant that she had to be one of the most mobile team members.
Because Sylia rarely engages in actual combat, her hardsuit is not seen much. But when she does go in for the kill, she does puts the saying 'Hell hath no fury like a woman scorn' to shame. Her hardsuit is equipped with a retractable katar style sword blade that she uses for fatal attacks to boomers, or even humans if needed, who get too close. Her fighting style is even more brutal and savage than that of Priss. Her suit is mainly made up of Silver/white colors with some teal and pink . Her suit is also very stealthy, allowing her to move around undetected by the enemies. And just like the original hardsuit, this one is also able to sustain flight, and is still the only one to do so.
