X-23 (real name Laura Kinney; alias Wolverine) is a fictional superhero appearing in American comic books published by Marvel Comics, most commonly in association with the X-Men. The character was originally created by writer Craig Kyle for the X-Men: Evolution television series in 2003, before debuting in the NYX comic series in 2004. Since then she has headlined two six-issue miniseries written by Kyle and Christopher Yost, a one-shot and self-titled series written by Marjorie Liu, and All-New Wolverine by Tom Taylor.
X-23 was apparently the clone and later adopted daughter of Wolverine, 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 attended school at the X-Mansion, and eventually became a member of X-Force. Like Wolverine, X-23 has a regenerative healing factor and enhanced 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. In July 2018, the character returned to her original moniker of X-23.
