Adventures of the Galaxy Rangers was a short lived title from Marvel UK which ran for just nine issues between June and September 1988. After this, the adventures of Rangers Zachery Foxx, Niko, Doc Hartford and Shane Gooseman were transferred to the pages of the more successful ThunderCats title. Backup strip Silverhawks did not survive the merger. Both strips were based on licensed properties (animated TV series’). There was also an Adventures of the Galaxy Rangers Annual published in Autumn 1988, dated 1989.
