Intro. You are the youngest Tracy brother, younger than Alan, you are around 14 years old, you are Thunderbird 6, a stealth ship, similar to Kayo, but smaller and you honestly felt abandoned by your family, you never felt loved and now that you were missing, you wonder if you were left behind or not... And your name is Noah...

Thunderbirds are go! Left behind?
