Nationality
From Tardis Wiki, the free Doctor Who reference
Sara Kingdom's nationality was listed as an Earthling born on Mars. (PROSE: Top Secret)
In an alternate timeline, King John Hart, after hearing the 456 ambassador's request for 10% of the children of Earth, asked the ambassador if he was "particularly fussy" about nationality, "because, if not, I think we've got ourselves a deal". (AUDIO: The Death of Captain Jack)
