For the purposes of this list, a "Judoon story" is one in which one living, authentic Judoon plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. For this reason, stories such as The Timeless Children are absent due to the Judoons' only contribution being references to past Judoon stories. Stories like The End of Time, The Pandorica Opens and A Good Man Goes to War are also not included due to the Judoons' cameos being of no consequence to the plot of the story.
For the purposes of this list, a "Quark story" is one in which one living, authentic Quark plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story.
