Ooh, I had a fun idea for a character... You'll see.
Figure it'd be interesting to start Supergirl from scratch and let the course of events dictate whether she becomes a hero like her famous cousin or a villain.

Powers: Linda has all the abilities of a Kryptonian under a yellow sun. Aside from incredible reflexes and senses, she is superhumanly fast and strong. The young woman can shoot fire from her eyes and create gales with her breath. She can leap vast distances and fly. She has X-ray vision that works on everything but lead. And of course she can project concentrated beams of heat from her eyes.
Martial Arts Training: She has no martial arts training.
Skills: Linda is a great singer and writer.
Costume: N/A
Equipment: Aside from her "smart phone," she's got nothing fancy.
Personality: Linda is an incredibly intelligent young woman with a powerful memory. She loves to learn and explore; her curiosity is seemingly insatiable. The girl has no self-restraint. Rules and boundaries are for those that feel bound by them. Not that she's rude or offensive but most of the time she does what she wants when she wants and doesn't really care what others think of her. The girl is a free spirit whose philosophy is live and let live.
Much as she enjoys having a good time, she's always got an eye to the future. She may not hold herself back from seeking answers to her questions but control and discipline are very much a part of her nature. She is diligent and strong-willed. Nothing is going to get in her way when she wants something. The end justifies the means for her...
Aware of the fact that she's not human (at least not entirely) she has a rather cynical view of the species
Home sapiens. The vivacious girl has a natural charisma and can be very polite when she wants to be. She is capable of being ruthless and manipulative. Regret is a foreign concept to her. What's done is done. A woman of strong emotions that she rarely lets get the best of her, she tries hard to accept and adapt, roll with the punches...
She yearns to know where she came from and what she's capable of. Linda very much enjoys her abilities. Right now she's focused on getting an education and increasing her control. But one day she knows she's going to do something great with the gifts she's been given...
Short Bio: Linda was apparently the survivor of a freak accident. A car was struck on a long, lonely stretch of road in Oklahoma. The infant was apparently the only survivor. Edna Danvers was working as a nurse at the hospital where she was taken. It didn't take long for her to figure out something was different about the baby.
She called someone she suspected could help them. Her husband had been hired by one of LuthorCorp's subsidiary companies after losing his job. A rocket scientist and engineer, he had been ridiculed for his beliefs in life on other planets. He had been dismissed by MIT. The job offer had been a godsend. So he agreed.
The adoption took place through Midvale Orphanage. They decided to name the girl Linda. She quit her job at the library to be a full-time mother. And it was a full-time job! Linda was a precocious and extraordinarily healthy infant. It didn't take long for certain abilities- namely her extensive healing abilities and strength to become evident.
She was homeschooled through elementary school. But she managed to convince her parents to let her go to public school for middle school. It was an adjustment for the young woman but she took to it quickly. Linda just barely managed to keep things in check for PE and had no interest in sports. But she was involved in the student government, show choir, and school newspaper.
When puberty hit, some of her other gifts started to manifest. Her time was full of extracurriculars and homework. Linda would get away as often as she could, run someplace far away to practice and learn control and still be back in time for dinner. As she got older the curfew and rules got more annoying and she started to question them...
She started acting out more as she got older. Linda wasn't the teacher's pet anymore but she refused to touch drugs, alcohol, and sex was just out of the question. Her parents did their best for her. They loved her, even if they couldn't tell her where she'd come from or what she was.
She got a job at a local restaurant working as a hostess, then a server, then a waitress, when she was 16 and that helped settle her down. Two years passed as she continued to mature and learn. By the time her senior year rolled around, she was ready. Applying to various colleges, she finally settled one. A full ride scholarship and the offer of a paid internship from a local paper helped. Bidding her parents good-bye, she packed her things and prepared to take the first step of the next leg of her journey.
Weaknesses: The mere proximity of green kryptonite makes her sick and vulnerable. It temporarily prevents her from using her abilities. Other varieties of kryptonite have various affects- none of them pleasant. (Blue is the only color that doesn't affect her.) Powerful solar flares can cause her to lose control of her powers. Her cells seem to store solar energy but if she doesn't "recharge" periodically, her strength and speed will be that of a normal human's. Only a yellow sun has the advantage of giving her abilities beyond her enhanced physical attributes.
