This issue is a variant of Doctor Who (IDW Publishing, 2011 series) #12. There exist further variants.
Credits, brief recap of who the Doctor is, and an illustration of the Eleventh Doctor and Santa peering out of the TARDIS.
This story is told completely without dialogue until the second last page when the Doctor breaks the fourth wall and addresses the reader, wishing them a Happy Christmas. This moment is a tribute to the famous Christmas Day 1965 episode of the original TV series, The Feast of Steven (a standalone chapter of The Daleks' Master Plan), in which the First Doctor does the same thing, but on camera. Roboforms, androids usually seen dressed like Santa, were introduced in the 2005 Christmas special The Christmas Invasion. Due to the fact the Doctor breaks the fourth wall and meets Santa, it is doubtful that this story is considered canonical with either the IDW comic book series or the franchise in general.
