In Central City.............................
Nora was running as fast as she could possibly run. To the people around her, she appeared to be a combination of purple and blue lightning. She smiled as she thought about her daily routine.
My name is Nora Snow-West and I am the fastest girl alive. When I was a child, I saw my mom killed by something impossible. My mother went to prison for her murder. Then an accident made me the impossible. To the outside world, I'm an ordinary forensic scientist. But secretly, I use my speed to fight crime and find others like me. And one day, I'll find who killed my mom and get justice for my mother. I am XS.
Many years ago...............................
Nora Snow-West/XS and Natalie Thawne/SlipStream had been battling each other for centuries and neither one had any real edge over the other. Their combined power of super speed was so strong that it affected the entire multiverse, turning all men and women into futanari women.
Far in the future.............................
XS and SlipStream were battling each other in a fight that was intense. Surges of lightning blasted through the city as the two speedsters battled to defeat the other. After a long battle, the two speedsters were facing off against each other several hundred of miles away from each other.
"I thought we had the same goal in mind," Natalie said. "We were friends, Nora. I thought we were more than just friends."
Nora grunted. "You stopped being my friend when you used your powers to hurt people," she said. "Innocent people; men, women, children. Mothers and fathers. Brother and sisters. Entire families destroyed by you and your desire to be the best. You are not a friend,"
Natalie scuffed. "This world has changed so much since we first faced each other," she said. "It needs someone who can help the strong and powerful, not the weak and useless. It needs a hero, it needs me."
Nora glared. "You're not a hero, Natalie," she said. "You're a monster. A hero protects everyone and everything in the world. You are a disgrace to humanity and I'm going to stop you."
Natalie seemed worried. Suddenly she smiled. "Well then, what if you didn't exist?" She asked. "You wouldn't be able to stop me then, would you?" Nora realized what Natalie had in mind. Their lightning surged through their bodies; Natalie's red and yellow; Nora's blue and purple. Natalie then sped off, with Nora speeding off right behind her.
After learning XS's secret identity, Thawne traveled back in time to kill Nora as a child to erase her foe from existence.
Years ago in 2009.............................................
Caitlin and Iris were both happy with their new family; 7 year old Nora and her 6 year old sister Bailey. Caitlin told Nora took have sweet dreams and headed downstairs. Suddenly young Nora heard a noise coming from downstairs and she went to investigate. She saw the lightning of red, yellow, blue and purple surging through the room. She saw Caitlin trapped in it. For a split second, the young Nora saw a woman in yellow in red and yellow lightning.
Before Thawne could complete her mission, she was thwarted by XS of 5673 who brought the younger Nora to safety. The enraged Natalie then killed Caitlin Snow-West and framed Iris Snow-West for the crime instead, being known as the Lady in Yellow after the incident as well as taking Bailey with her. However, Natalie's connection to the Speed Force began fluctuating, trapping her in the early 21st century. Realizing that Nora was the only way to return to her time, Natalie killed a woman, Wendy Stryker, in order to assume the identity of Wendy Stryker as the director of S.T.A.R. Labs, and to push through for the creation of a particle accelerator to ensure that Nora would become XS. Posing as Stryker, Natalie mentored XS and became the leader of a team that she assembled to stop the meta-human threats, to increase her protΓ©gΓ©'s speed so that Natalie could use the heroine's connection to the Speed Force to return to her own time.
Somehow Caitlin had survived the attack and was alive.
Back in the present day.....................
Nora was sitting in her room. She was looking at a picture of her and her sister. She missed her sister so much. She was going to find the woman who ruined her life and make her pay for it all.
Suddenly she received a message from S.T.A.R. Labs that she was needed to save the people of Central City.
A gun shop owner was packing up her shop. Suddenly a woman named Danielle Black entered the store. Danielle was a 34 year old caucasian woman with long brown hair, blue eyes, was 5 feet 4 inches tall, 126 lbs, had a slim body, had enhanced 32E breasts, had her pubic hair trimmed in the form of a triangle or a landing strip, a pierced navel, and a 15 inch long cock.
Danielle had the following powers;
Meta-human physiology: After Danielle was struck by the energy of the Particle Accelerator explosion, this altered her DNA and supercharged her cells, enabling her to manipulate her cells.
Cellular replication: Danielle could replicate her cells at superhuman speeds, allowing her to create life-sized clones of herself. She could also use this power to create multiple limbs on her body. Danielle can also use cellular replication to rapidly regenerate damaged tissue, missing organs, or severed limbs.
Molecular replication: Danielle also could replicate the molecules of anything she was wearing or carrying, however was unable to replicate more complex tools like automatic weapons.
Danielle had the following abilities;
Genius-level intellect/Master scientist: Danielle was a brilliant scientist, having conducted ground-breaking research in cellular regeneration and cloning. She was nearly successful in replicating human organs, such as hearts. Danielle's research was so coveted that Simone Stagg stole it for herself.
Indomitable will: With Danielle's new-found powers requiring her to split her attention, she displayed an incredible ability to multitask, able to effectively coordinate all her copies for her group attacks. Likewise, Danielle was shown to be able to create hundreds of clones before feeling the stress.
Skilled marksman/Firearms: While attacking Stagg, Danielle and her clones were proficient in the use of firearms.
Danielle had the following weaknesses;
Fatigue: Despite the ability to create large amounts of duplicates of herself, it results in Danton's body becoming over-stressed, which will exhaust her.
Hive mind: If Danielle is incapacitated, distracted, or is too far away from her clones, her copies become inactive, falling unconscious, as Danielle cannot focus her mind on them to give them commands.
Danielle was looking at the different types of guns that the shop had. She then picked up a gun and started to dry fire it.
The owner was not interested in selling the property to someone like Danielle.
Danielle smiled. "I'm sorry to hear that," she said. "I had hoped that you could help us with our problems but it seems like you don't want to." Danielle cloned herself and the six of them began to beat the owner up. Black then turned around and proceeded to take the weapons that she wanted.
With help from Cisca, Nora began to use her abilities to stop minor crimes and help citizens across the city. As Nora began to push herself more and more, she began to develop debilitating side effects. While assisting Iris on a school assignment, Nora witnessed a robbery by a crew of women, but fainted while trying to stop them.
The S.T.A.R. Labs team determined that Nora had become hypoglycemic from the use of her abilities due to a sped-up metabolism and needed to ingest more calories to maintain her energy level.
The team eventually learned that the robbers were actually one woman, Danielle Black, who had the ability to create clones of herself. Cisca names Black 'Captain Clone'. The team was not impressed with the name, and Cisca said that she would come up with a better nickname.
Black wanted to kill her former employer, Simone Stagg, who stole Black's cloning research.
