Panini have since extended their line to include other characters within the Marvel Universe. In addition to "Essential X-Men" and "Astonishing Spider-Man" came "Wolverine Unleashed", in which Wolverine's solo comic was reprinted. The comic ran for 54 issues before it was renamed "Wolverine & Gambit" to allow reprints of the "Gambit" series, and subsequently "Wolverine and Deadpool" when the Gambit material had been exhausted and Deadpool was introduced as a replacement in 2004. "Marvel Heroes Reborn" was released in 1997, to introduce the new "Heroes Reborn" saga, and expand the range of characters in Marvel UK's lineup. It was initially published with only two strips (or 56 pages) but this was expanded to 76 pages (commonly 3 strips) from issue 17 onwards. Unfortunately, this title was short lived due to continuously lagging sales, and was eventually cancelled in 2000.
