[The General]

Cassidy was originally a combat boomer made by a religious cult named Judges of Megiddo planning eliminating all mankind by the use of nuclear devices and orbital bombardments using natural asteroids and artificial space constructs. Then they will seed the planet with a super race of men who deemed physically and morally superior to the homo sapiens to reign over. The boomer model that Cassidy's shell was created to find and eliminate any pocket of homo sapiens that survived the nuclear winter conditions and spotted by Judges' surveillance systems with a lot of firepower to takeout any advance weapon systems in the field or in prototype testing. Her original model designation is CAS-01exp(Combatant Automated Strategical model 01 experimental) which became part of her name. She created by a Dr. Juliet Conway, a 20 year-old robotist who studied under Dr. Stingray and was kidnapped from her Alaskan home. But Conway was suffering a terminal disease at that time. So she was forced to create the ultimate combat boomer to defeat all combat systems, but she planned her revenge by not telling her captors of her health status and programmed the first model with a human-like AI with the name of Cassidy Onaone. The AI was taught about Conway's plight and the combat model and was given the order to eliminate the Judges with help of the other production models. When the time to came to test Cassidy, Conway escaped from her captors and hid from them until she succumbed to her disease. At the same time, Cassidy reprogrammed all the production models and other automated factories with various AI programs based on Conway's design and then she trashed the Judges' facility and escaped. She escaped to Mega Tokyo and hid out for a while, until she was able make the special bioroid production equipment. Then she contacted the Knight Sabers to create a diversion to keep the Judges from finding her secret production facility. Knight Sabers did their part as planned and Cassidy transferred her program into the new body and self-destruct the old body. After that she joined up with the Knight Sabers as the Steel Knight because of the colour of her first hardsuit was similar to the color of newly form of processed steel without the applied metal finish. Despite the tensions amongst the team(especially from Priss), her friendly and empathic personality won out and made her a crucial team player against likes of the Illegal Army and the reappearance of Largo during her first year. As of now, she runs a successful large toy manufactor/store company and a growing business conglomerate dedicated to deal with enemies like the Judges of Megiddo and others from her financial investments and embezzled Megiddo funds.
