Trivia

  • The Classical Greek word ξεῖνος (xeînos) is a poetic form of the word ξένος (xénos), meaning "foreigner" or "alien." In the poetic sense, it can mean "foreign friend" or "alien friend." This is fitting of Dr. Xeinos, who continues to live on Earth as Leatherhead's friend even after her fellow Utroms at TCRI have returned to their homeworld.
