When a secret program attempted to recreate the Weapon X experiment, they failed to secure a test subject who could survive the bonding process of the virtually unbreakable metal adamantium. Seeking to take the project in a new direction, Dr. Sutter recruited mutant geneticist Dr. Kinney&tasked her with creating a clone. Using the only available genetic sample from Weapon X, which was damaged, they were unable to salvage the Y chromosome after twenty-two attempts. Kinney proposed they create a female clone, and though her request was denied, she still went ahead&produced a viable female subject&she gave “birth” to X-23. Raised in captivity, X-23 was trained to be a weapon. Kinney did her best to ensure the child retained some semblance of humanity but her efforts were in vain. X-23 was subjected to radiation poisoning in order to accelerate the activation of her mutant gene&forcibly extracted her claws to be coated with adamantium. Before fleeing the facility with X-23, Kinney gave her one last mission to destroy the pods&kill Zander Rice. However, Rice was able to exact revenge on Kinney from beyond the grave, as he exposed X-23 to the trigger scent, sending her into a rage that caused her to kill her mother. As she was dying, Kinney named her daughter Laura.
