This 84-page special edition was part of Marvel's "Must Haves" line, designed to reprint key issues that had sold out or were in high demand. NYX #4 and #5 are notable for featuring early appearances of Laura Kinney, also known as X-23, the female clone of Wolverine. These issues continue the "Wannabe" storyline, focusing on a group of teenage mutants surviving on the streets of New York City.
