In the UK there was also a short-lived Sunday comic strip and a series of Christmas annuals. Whilst there were some slight connections (both projects occasionally featured the work of regular Sonic the Comic artist Richard Elson), the projects were largely separate from one another, with the Sunday comic and annuals preferring self-contained gag strips over Sonic the Comic's continuing plot lines and maturer stance.
A series of six Sonic Adventuresgamebooks were published in the UK between 1993 and 1996 by Puffin under the Fantail label.
