So, as I've started to rewrite my DBZ OC's ( Kyone's:
[link] ) life-story, it would be important to tell a bit about her mother.
Honestly, about her is known very little . According to the chronology of events, Kyone was born in the year 720-721. These were years when the Saiyans united and began a rebellion. They plunged into an all-out war with the Tsfruians and overwhelmed them.
In general, the name of girl's mother was - Feyoha. And it is unknown how she met Kyone's father. Because the girl was born with blue eyes, it could not be a Saiyan ( cuz we all know that purebred Saiyans have only black hair and eyes), and it is also unknow how a strong warrior of a wild race could fell in love (?) with someone who was not even one of her own race, and moreover - bear his child. But he deffinitly wasn't one of Tsfurians as well. And the fact remains the same - Kyone was born as a half-breed. Since those Tsfurians were pretty advanced race, it can be assumed that they could come into contact with other races, and probably one of these races' representative was on their planet where he met Feyoha. What happened to him after is also unknown, in any case for Feyoha. So with the mother Kyone lived only 4 years, and then she was stolen by her own father, who suddenly appeared on the planet again. This all was a mystery. And raises many questions: Why did the mother let this happen, or, for example, how COULD all this happen?
The point here is like this: the birth of a blue-eyed girl could not go unnoticed, and who knows what could have done to her other Saiyans (because except Goku, Saiyans never come into an intimate contact with other races. And even if they did ... well, it remains unknown) if they found out she was not a purebred. It seems that Feyoha allowed Kyone's father to take his daughter, probably thinking it would be safer for her child. In any case, she didn't do it just to get rid of her child, because the girl's father and most of Kyone's memories bout Feyoha were good.
According to these memories, Kyone's mother was young, brave, and protected the girl from other Saiyans, trained her to fight, as far as it was possible to train a child of her age, and tought her how to survive.
After the father took her away, she hadn't seen her mother for a long time. Already after Kyone was found by Freeza's people, she met a saiyan-woman, who'd started to help her, and was her mother very reminiscent. But it didn't last long. In general, after becoming one of Freeza's soldiers, Kyone never knew what fate befell her mother. Although there were some rumors that she'd died on a mission.
