X-23 (Laura Kinney) is a fictional character appearing in comic books published by Marvel Comics, most commonly in association with the X-Men. She was originally created by writer Craig Kyle for the X-Men: Evolution animated series before debuting in the NYX comic series in 2004. Since then, she has appeared in two six-issue miniseries written by Kyle and Christopher Yost and her own self-titled series written by Marjorie Liu.
X-23 is a female clone of Wolverine. Like Wolverine, X-23 has a regenerative healing factor, superhuman strength, senses, speed, and reflexes. She also has retractable adamantium-coated bone claws in her hands and feet. In 2015, the character succeeded her "father" in adopting the name and costume of Wolverine in the series, All-New Wolverine.
Cloned from a damaged copy of Wolverine's genome, X-23 was created to be the perfect killing machine. For years, she proved herself a capable assassin working for an organization called the Facility. A series of tragedies eventually led her to Wolverine and the X-Men. She attends school at the X-Mansion, and eventually became a member of X-Force.
