The Cameos & Crossovers section of the wiki details elements in non-Metroid series media officially licensed by Nintendo, that contain one or more references to the Metroid series. Originally, many links to these medias were created and opposed by many users (see the RfC linked above), and as such were removed. All media-related objects meeting to the above criteria are, as directed by this policy, to be put through a systematic analyzing process, known as the 3-Point Rule/System.
