Universe X (2000, Marvel)

Universe X ran for 14 issues (2000–2001). Publishing format: limited series. Issue #X is labeled in indicia as a one-shot named "Universe X: X Vol. 1", with a different barcode sequence. However, this is being treated as an aberration as the primary story from this miniseries follows directly from issue #12 to issue #X, the cover style does not indicate a change, and the covers of all issues including #X combine to create a single image.
