X-23, Wolverine's clone and as of this writing the only female headlining a solo title at Marvel, has had her series canceled. This is the latest in a long run of cancellations from Marvel, including miniseries Victor Von Doom, Destroyers, Alpha Flight, and All-Winners Squad. X-23 is the first of these to have been an ongoing series, though it's not likely to be the last as Marvel looks to cut costs and boost sales by trimming titles.
