Biography

Born on 20 June 2043, Tin-Tin is the daughter of Kyrano – an old friend of, and manservant to, International Rescue founder Jeff Tracy. She joins the organisation shortly after it starts operations, having inadvertently become involved in IR's first mission when the maiden flight of Fireflash, in which she is travelling from London to Tokyo, is sabotaged by her villainous half-uncle The Hood ("Trapped in the Sky"). Her further education, specialising in mathematics and engineering, was fully paid for by Jeff in gratitude for her father's service to him ("Trapped in the Sky").

Tin-Tin performs a variety of roles on Tracy Island, IR's base of operations. They range from a secretary to Jeff ("Terror in New York City"), to a laboratory assistant to the scientist and engineer Brains ("City of Fire", "Danger at Ocean Deep") to active participation in missions, most notably the rescue of the Sun Probe spaceship ("Sun Probe"). She is also known to accompany Lady Penelope on espionage missions ("The Cham-Cham") and is a qualified pilot. Tin-Tin is romantically involved with Alan Tracy, although their relationship is briefly strained when Tin-Tin's ex-boyfriend, Eddie Houseman, visits the island ("End of the Road").

Broadcasts of TV series in Japan typically include subtitles introducing the names of characters when they first appear on-screen. Thunderbirds episode introduce Tin-Tin as "Min-Min". Since there is no character for "ti" in Japanese, "chi" is usually substituted; however, chin-chin is a Japanese colloquialism for the male phallus.
