“The first trailer for Logan dropped [recently], giving us confirmation of the long-standing rumor that comic book hero Laura Kinney—a.k.a. X-23—will be in the movie. If that name doesn’t ring a bell for you, we’re here to help: it’s because little Laura could end up being the key to the future of Wolverine on the big screen.
To put it simply, Laura is a female clone of Wolverine, first introduced in the comics in early 2004. She was actually first created for two episodes of the animated series X-Men: Evolution’s third season by Craig Kyle and Christopher Yost, before Marvel decided to bring the character over to their comics. Her first comics series, NYX, showcased the teen X-23 in action with no details on her mysterious past, which wouldn’t be fully unveiled until she got her own self-titled miniseries in 2006 and 2011, X-23: Target X and X-23: Innocence Lost.
In the comics, ever since Wolverine escaped the Weapon X project, there were attempts to recreate the successes that lead to his adamantium-encased bone, but they all failed. Martin Sutter, the head of the original Weapon X program, recruited a mutant geneticist named Sarah Kinney to lead a new version of the project—one that, instead of simply trying to bond adamantium to a live test subject, would instead simply clone Weapon X’s biggest successes.
Kinney faced a problem, though. The project’s last sample of Logan’s DNA was heavily damaged, and attempts to make a male clone failed 22 times. Kinney suggested to Sutter that a female clone be created out of what was left of Wolverine’s material—eventually he agreed, leading to the birth of X-23. (Long story short, when Sutter refused at first, Kinney defied him and made a female clone anyway, which led Sutter’s sadistic protege Zander Rice to force Kinney to be impregnated with the clone as “punishment” for defying Sutter…).”
