An anthology title, it features stories that focus less on the main continuity and more on peripheral events occurring with the X-Men characters.

This title allowed new and lesser-known writers and artists to write and draw X-Men comics.

This was particularly unique during the late 1990s when most X-Men titles frequently had story arcs that were several issues long.

It ran as a quarterly feature releasing four issues per year until late 2002 when it converted into a monthly title.

This title was released in weekly chapters exclusively in Marvel's Infinity Comics.
