She’s actually an opposite gender clone/sister/daughter thing of Wolverine that took up his mantle as of recent events. I like to imagine her conception went like this:

Shadowy organisation: (to sponsors) So remember that weapon X thing a while ago to make a mutant weapon that went disastrously wrong and resulted in a feral, razor tipped madman that killed all the staff and is still killing guys like you? We plan to do that again but this time grow one from scratch, abuse it physically and mentally all it’s life while teaching it assassination skills and weapons training to use it for the occasional hitjob.
Sponsors: … Well …
Shadowy organisation: Did I mention it’s going to be a chick?
Sponsors: (lifts out suitcase of money) I’m sold.

Laura why are you perfect
