Marvel Universe X-23

X-23 (Laura Kinney) is a fictional comic book superheroine appearing in books published by Marvel Comics, in particular those featuring the X-Men. X-23 is a female clone of Wolverine. She is a clone created using a damaged sample of Wolverine's DNA. The Y-chromosome was the damaged portion, therefore they needed to replace it with the undamaged X-chromosome, which is why she is female. Wolverine essentially regards her as a surrogate daughter.
