"But the girl, she's like a machine. I've never seen anything like it. She's so small... There are moments when I look at her, I just wanted to laugh. But I'm not laughing now. I'm just glad we're on the same team." - Domino
When a top-secret program attempted to recreate the original Weapon X (now Wolverine) using a damaged cellular sample, they were unable to salvage the Y chromosome. Dr. Sarah Kinney, a geneticist specializing in mutation, was brought in and proposed creating a female duplicate. Although her request was initially denied, Kinney produced a viable female subject anyway, prompting the program's director, Dr. Martin Sutter, to reconsider. Despite resistance from his protégé, Dr. Zander Rice, who was raised by his father's colleague after his father was killed by the original Weapon X, Sutter allowed Sarah to proceed. Zander, feeling slighted by Sarah's underhanded approach, forced her to play surrogate to the clone, and she gave birth to 'X-23,' the 23rd attempt to clone Weapon X.
Sarah, now disgusted by the program's intent to create a mindless killing machine, stayed on to try to remain a good influence and protector to her surrogate daughter. Years passed, and X was trained in multiple martial arts by a sensei, Tanaka. One day, to test X, Rice placed a trigger scent on Tanaka's sword, designed to enrage X. Unable to control her feral response to the chemical, X lashed out and killed her sensei in cold blood, which assured Rice that she was ready for the field. At ten years old, X-23 was sent on her first mission for The Facility. X was successful, being sent out many more times, one after another, killing dozens along the way, and left emotionally stunted, at best, by the experience. Despite Sarah's best intentions, X-23, having being raised as a prisoner, with extremely little human interaction, tortured with excruciating surgeries, and trained and brainwashed for many years, had become exactly what Rice had envisioned, a feral assassin at his beck and call.
Eventually, Dr. Rice, in a vain attempt to get revenge on the original Weapon X, left X-23 behind on a particularly dangerous mission, hoping it to be her last, but she managed to survive and return to The Facility. Finally, Zander persuaded his father figure to hand over the reigns of the program to him, while secretly ordering X-23 to kill Sutter, his wife, and their son, who was, in reality, the product of an affair between Zander and Mrs. Sutter. X-23 went through with the mission, killing the couple, but seemingly refused to murder the boy. Meanwhile, Zander revealed to a shocked and dismayed Sarah, a chamber filled with dozens of incubating pods filled with X-23 duplicates. Already mortified by Zander's most recent revelation, once Sarah learned of X-23's latest mission, she gave the girl one of her own: Destroy the incubation pods, and kill Dr. Zander Rice.
X-23 succeeded, setting explosives in the pod room, and killing every scientist and soldier that got in her way. Encountering Rice, X beat him to the brink of death, but as she was disgusted by his actions, and didn't want to become like him, X-23 stopped before killing Rice, and left him to die with his other creations. Nearly free of her torturous past, X-23 walked out of the building as the explosives went off, seemingly destroying the program that had spawned her. Her closest friend, Dr. Kinney, was waiting for her. Unfortunately, Rice had placed a trigger scent on Dr. Kinney earlier, and as X-23 detected it, her programming took over, and X fatally attacked the closest thing she had to a mother. As she lay dying, Kinney told X that her real name was Laura, not X-23, but the doctor died before she could finish saying "I love you." Luckily enough, a letter that Dr. Kinney had been writing to X-23 was on her person, detailing her history and personal feelings toward her daughter and the program. Also enclosed were legal documentation, and files on the first Weapon X, Wolverine, and his home, the Xavier Institute, that Kinney hoped would lead X to a better life. The Facility destroyed, all that was left of the program was X-23 and a sample of the trigger chemical.
X-23's main mutant power, much like Wolverine's, accelerated healing which allows her to regenerate destroyed or damaged tissue and organs at a much greater speed and efficiency that most humans and mutants. She can completely heal injuries that caused massive damage to tissues and loss of blood, like bullet wounds, cuts or slashes and even deep puncture wounds, in a matter of minutes. Her accelerated healing is so advanced that she can reattach severed limbs. Her accelerated healing also allows her immunity to all poisons and almost all drugs. Also due to her advanced immune system, X-23 is immune to all known diseases and infections.
Also like wolverine X-23 has super human senses, she can see at a much greater distance than most with almost perfect clarity, and also has perfect clarity in almost complete darkness. Her hearing is also as enhanced as her eyesight, allowing her to hear sounds ordinary humans don't and hear sounds that ordinary humans do, but from a much greater distance. She can also use her enhanced sense of smell to track targets.
Much like Wolverine, X-23 has 6 retractable claws, although there are some differences between them. Firstly, only two claws come out of each hand, the other 'claw', although it would be more accurately classed as a 'blade' come out of between her second and middle tow. The second difference is that her 'claws' are made of extremely strong bones, covered in adamantium, unlike the man she's a clone of, her skeleton is not adamantium.
