When a top-secret program attempted to recreate the original Weapon X experiment that involved the feral mutant Wolverine, they failed to secure a test subject who could survive the bonding process of the virtually unbreakable metal Adamantium to their skeleton. Seeking to take the project in a new direction, the project's director, Doctor Martin Sutter, recruited renowned mutant geneticist Doctor Sarah Kinney and tasked her with creating a clone.
Megan Fox as "Laura Kinney"..!!
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 initially denied, she still went ahead and produced a viable female subject, prompting Sutter to reconsider. Despite resistance from his protégé Doctor Zander Rice, whom Sutter had raised after Rice's father had been killed by a bestial Wolverine at the original Weapon X Project, Sutter allowed Kinney to proceed. As revenge for her insubordination, Rice forced Kinney to act as the surrogate mother for the clone, and she gave birth to "X-23".
X-23 secretly followed Wolverine on his investigation of strange activity in the Canadian Rockies. Ambushed by the Hauk'ka, evolved Saurians from the Savage Land, X-23 managed to escape and alert the X-Men. Traveling to the Savage Land, X-23 and the X-Men teamed with the Land's lord Ka-Zar and his circumstantial allies, the Savage Land Mutates, to prevent the Hauk'ka from destroying human civilization by controlling the weather-manipulating X-Man Storm.
As a clone of Wolverine, X-23 possesses most of his mutant powers. However, since she is still in her teens, some of her powers aren't as developed as those of Wolverine.
Regenerative Healing Factor: Like Wolverine, X-23's primary mutant power is an accelerated healing factor that enables her to regenerate damaged or destroyed tissue with far greater speed and efficiency than an ordinary human. She is capable of fully healing injuries resulting in massive tissue damage and blood loss such as multiple bullet wounds, slash wounds, and puncture wounds within a matter of minutes. Her healing factor is developed to such a degree, she is capable of reattaching severed limbs, such as a hand. She has also proven capable of regrowing an entire arm on her own (Elixer was incapacitated at the time). Her healing factor may fluctuate with her psychological state as battle wounds tend to heal very quickly, but her self inflicted cuts appear to remain visible for some time.
Foreign Chemical Immunity: X-23's natural healing also affords her the virtual immunity to poisons and most drugs. She can be affected by some drugs, such as tranquilizers, if she is exposed to a massive dose.
Disease Immunity: Due to her highly efficient immune system, X-23 is immune to all Earthly diseases and infections.
Superhumanly Acute Senses: X-23 possesses superhumanly acute senses that are comparable to those of certain animals. She is capable of seeing at much greater distances, and with perfect clarity, than an ordinary human. She retains this same level of clarity in near-total darkness. Her sense of hearing is enhanced in a similar manner, allowing her to both hear sounds that ordinary human's can't and to hear sounds that ordinary humans can, but at much greater distances. X-23 is able to use her highly developed sense of smell to track targets by scent with an impressive degree of success, even if the scent has been eroded by natural factors, such as the weather.
Superhuman Stamina: X-23's muscles produce considerably less fatigue toxins during physical activity than the muscles of an ordinary human. She can exert herself at peak capacity for about 24 hours before fatigue begins to impair her.
Superhuman Agility: X-23's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete.
Superhuman Reflexes: X-23's reflexes are enhanced to levels that are beyond the natural physical limits of the finest human athlete.
Bone Claws: X-23's skeleton includes two retractable bone claws in each arm and one in each foot that she can extend and retract at will. These claws are housed beneath the skin and muscle. Unsheathing them causes her skin to tear and bleed, but the wounds are quickly dealt with by her healing factor. X-23 can unsheathe any number of these claws at once, although she must keep her wrists and/or feet straight at the moment the claws emerge. The claws are naturally sharp and tougher than normal human bone, allowing X-23 to cut through most types of flesh and natural materials.
Longevity: Presumably, because X-23 is a clone of the mutant Wolverine, her healing factor will also provide her with an extended lifespan by slowing the effects of the aging process.
Superhuman Durability: She was capable of fighting the Hulk without sustaining any severe injuries and surviving energy blasts from Nimrod (even if she required healing and nearly died).
Uni-Power: Laura has been occasionally seen wielding the powers of Captain Universe, and has the mark on her hand.
