I'm running out of western-esqe names, so I'm recycling the one I used in my RP sample, since I like it and fits what I have in mind.
Name: Velvette Haziel
Age: 19
Pokemon Species: Froslass
Personality: If anyone were to ask someone who knew the Haziel family about Velvette, they would be told about a gorgeous, quiet, and polite girl who loves her siblings. While not incorrect, this font is the result of her upbringing.
As the eldest daughter of a well-off family, Velvette is expected to be graceful, talented, and beautiful. The girl didn't disappoint. Since her earliest years, Velvette has been taught the proper etiquette fit for high-end gatherings, learned with the best scholars of their time, and met many prolific figures. Through it all, she did it for the sake of her family, never complaining and simply enduring.
At one point, she couldn't take it anymore. She fled her classes and hid herself in one of the less used rooms of her home. There, she found something that would spurn her on through her endeavors. It was an art room, paintings from various artists hung from the walls, intricate sculptures dotted the room, but what caught her attention is an inconspicuous portrait of her mother and father sitting in a bench looking at a sunset. Her parents looked very sincere in it, unlike the mask they wore on a daily basis.
From then on, she aspired to live her life to the fullest, living up to people's expectations but not letting it hamper her chances to do what she wished to do. She wears a mask of a calm, quiet heir when in front of other people, but few actually know of her hidden depth.
Whenever people visited her home, she would sit on the side, watching them. Often, she would slip in a few words for the sake of conversation, but otherwise is quite content not participating much.
She is very passionate about art, but often keeps her words in check, she learned to tinker during her spare time, and never out-right speaks her mind.
Overall, Velvette is an understanding girl, intelligent, and is open-minded about other's opinions. Above all, she values the importance of life and the emotions people express.
Appearance: Velvette's most striking change from her old look, is her hair. Where before it used to be a curtain worthy of her namesake, the top of her head is tipped with short, straight snow-white strands. It sweeps over to one side to resemble a tear-drop. Long strands falling down to the small of her back retained their purple coloring, but their tips on both ends are white. A few framing her face were capped with ice, but still flowed when she moves.
Her skin turned quite pale and tinged slightly blue. There are a few patches of her skin with unnatural coloring though, like her midriff which is a bright red in color, and the blue spot on her hands.
The few features she retained from her old life is her vibrant violet eyes, her delicate fingers and her bright, expressive face.
Background: Velvette is the elder of the first-born twins of the Haziel family of Sinnoh, but while her twin-brother went away on his Pokemon Journey, she stayed at her home and took care of her other siblings while one or both of her parents left for business.
The Haziel family is a respected family known for their trade of metals and Steel Works. They are the main producers of quality steel, capable of providing materials for ship building even overseas such as Hoenn. They participate in fair-trade, and promote customer satisfaction and employee safety. Still, they are not without enemies.
There came a day when Velvette's monotonous routine changed, when one of her younger brothers was taken from their home. To make matters worse, her mother, who was pregnant at the time, suffered from their loss the most. From that moment, she vowed to value life at its best, and find her missing brother.
Her twin returned to their home, blaming himself for not being able to protect them, even if he wouldn't have been able to do much for the culprit to have slipped past the many bodyguards of the family. Still, this left few to search for her brother, and she left on trips as her family's representative as her father searched for him, her loyal Pidgeot that she raised from infancy by her side.
She traveled to Kanto, and got caught on work, slowly losing contact from her family. It has been over a year since she last heard from her twin when an event that changed her life happened. It was under the cover of night, her Pidgeot resting inside its Pokeball by her bedside table, that she was taken.
It took two whole months before anyone noticed that Velvette Haziel has gone missing.
