GT-6 was the co-pilot on the StarWing test flight. When the ship was taken over by Prime Evil, GT-6 and pilot GT-7 hid themselves behind large mailbags in the main hold. There they were found by the Ghostbusters and Futura, who proceeded to help them regain the ship from Prime Evil, although they first found themselves locked up in the ship library. After the adventure had concluded victoriously for the Ghostbusters, President Gerald Vincent awarded a medal to the Ghostbusters, Futura, Belfry and the two robot pilots.
