Petronella Osgood once wrote a paper on the subject of nominative determinism with regards to alien species names. She posited, as River Song would also later describe, that alien races whose names resembled the form given to "villains [in] old B movies" might, as a result, be more inclined towards invasion and hostility. River referred to the Wampeerix as one such example. (AUDIO: The Power of River Song)
