Inclusion debates/Death's Head: The Body in Question
Death's Head: The Body in Question, first published in Strip #13-20 reveals the origin of Death's Head, a character iconic for appearing in Marvel, Transformers, and Doctor Who comics.
Even before The Incomplete Death's Head was ruled valid, the Death's Head stories Time Bomb! (comic story) and Do Not Forsake Me Oh My Darling! (comic story) have been considered valid for the appearances of DWU characters: Seventh Doctor/Dogbolter/Hob and Keepsake, respectively.
If a story having a character that originated in the DWU can make it valid, then Death's Head: The Body in Question should be valid for the appearance of none other than Keepsake's vulture, who first appeared in Keepsake (comic story).
