The term "DWM backup comic story" does not actually designate a formalised series. There was never a masthead featuring the term, and there was no particular consensus as to which strips could be considered "backups". On this wiki, the term means any strip appearing in any issue of DWM or its predecessors which: * is set in the DWU * doesn't feature the Doctor, or at least doesn't use him as the main protagonist * isn't clearly a part of the main strip's narrative * has no other series name * is original to the pages of DWM
