Reaper Destroyer Supplemental was a unique book with unique stories separate from the Reaper Destroyer comic book. The content is different with art and story that is not by the same people who produced the main book. However, the supplemental book rather than being given it’s own series was tagged in as being a variant cover of Reaper Destroyer. It should be it’s own book.
