Jamie Wayne 2.0 {REDO}

Hey, look at that! Jamie has an actual costume and not some hoodie from Hot Topic......

Jamie Wayne

Age: 16

Abilities: Although she has no superpowers, her intellect and skill in hand to hand combat makes her a formidable opponent against even metahuman opponent. She is also an Olympic level gymnast, making her incredibly flexible and agile. Jamie has also showed signs of invulnerability to telepathic attacks, after a failed attempt to enter her mind by Miss Martian

Jamie Wayne was 5 when her mother was killed. Her father, Silas Stone, was trying to create a inter dimensional transporter. However, when the machine glitched, a hostile alien escaped, murdering her mother and severely injuring her brother, Victor. This incident is the origin of Victor Stone, aka Cyborg. Silas was left with both his robotic son, young daughter, and piling bills. Needing a higher pay, Silas lands a job at Wayne Financial in Metropolis. Unfortunately for his children, a year after landing the job, the Kryptonian invasion (Man of Steel) results in most of Metropolis destroyed, including the building. Jamie, who was with Silas for Take Your Child to Work Day, was nearly killed by falling debris if it weren't for Bruce Wayne yanking her away in time. Bruce sees the destroyed building and knows her father had not survived. Knowing that made her an orphan, Bruce takes her into his home, adopting her as his own child.
Jamie is raised under his roof, becoming an official Wayne. Bruce trains her in hand to hand combat, teaching her everything about defense against any and everything, including metahuman opponents. Dick Grayson is also living under the Wayne roof, after his family died in the circus incident (before Man of Steel events). Jamie and Dick grow closer together throughout the years, becoming inseparable siblings.
By the time she was 13, the Justice League had been up and running. Bruce, seeing that Dick had become a major part of Young Justice, wants Jamie to also join the team, much to her dislike. She refuses on several occasions, even when approached by Dick himself, until she suddenly agrees out of the blue. She joins Young Justice, and the minute she walks in, she had already downloaded files on EVERYONE. She tells the shocked team members that there was no way she would join any team without knowing how to take each member down. This angers and almost frightens most of the team, aside from Dick, who kinda saw it coming. The suspicions of the team are confirmed after Jamie manages to dislocate Connor's arm during a sparring match. She explains that she'd fully co-operate with the team, as long as they 'play nice' and refrain from threatening her with their powers.
They still remain wary around the girl, but the overall avoidance of her completely has lessened...slightly.
Clark eventually talks to Bruce about her behavior, however, Bruce brings up the fact he was the same exact way when he joined the Justice League, and eventually she'll have a much deeper bond with the team. He, of course, is right, and after an awkward period of months, Jamie finally warms up to the team.

I may have kinda based the costume colors off of Nightwing, but hey, she's close to her big bro.

Don't own Batman, Superman, Nightwing, Justice League, or Young Justice and every other DC reference I mentioned, all goes to DC Comics
