Over the last decade, one Marvel superhero that’s seen an astronomical growth in popularity is Laura Kinney a.k.a. X-23. A practically unstoppable mutant with powers and abilities just like Wolverine, if only because X-23 was a clone of Wolverine.
Created by an offshoot of the Weapon X program, the institution that laced Wolverine’s claws with adamantium and turned him into a killing machine, they did so out of a desire to have a Wolverine they could control and call their own. After numerous botched attempts, scientist Sarah Kinney suggested they try and make a female rather than a male. The experiment was success and so it was that Sarah carried X-23’s cloned body to term. Then Marvel went ahead and changed X-23’s entire history in one fell swoop in this week’s Hunt for Wolverine: Adamantium Agenda #4.
Towards the end of the issue X-23, Luke Cage, Jessica Jones, Spider-Man, and Iron Man return from a battle with the villainous Mr. Sinister when Tony Stark drops a huge bomb on the team. After hacking Sinister’s files, Tony learns the truth about Laura and shares it with her. A) She is not a clone of Wolverine and B) Sarah Kinney was Laura’s biological mother. Of course such a reveal is rather huge, as it alters the foundation of X-23’s character, so we’re going to need further explanation and hopefully we’ll get it over time.
