A top-secret program is tasked to replicate the original Weapon X experiment that bonded adamantium to the skeleton of Wolverine. The project is taken in a new direction: Dr. Martin Sutter recruits renowned mutant geneticist Doctor Sarah Kinney to develop a clone of Wolverine. Also on the team is Sutter's protege, Dr. Zander Rice, who was raised by Sutter after his father was killed by the original Weapon X.
Since the only genetic sample from Weapon X is damaged, Kinney is unable to salvage the Y chromosome. Kinney proposes the creation of a female genetic twin. Her request is denied; Rice is opposed to the idea. After 22 failed attempts at reconstituting the DNA using a duplicate X chromosome, the 23rd sample yields a viable sample to combine
