Ultimate Spider-Man and X-Men is a Marvel UK title published by Panini Comics every four weeks. The title reprints one issue of Ultimate Spider-Man and one issue of Ultimate X-Men. The title is a result of a merger of Ultimate Spider-Man and Ultimate X-Men, two separate titles formerly published by Panini. The merger was a result of the two titles reprinting comics faster than they were being published in he United States. The title has also reprinted the Ultimate Nightmare mini-series.
