From the Super Mario Wiki, the Mario encyclopedia
Torque is a Spike Top that teams up with Luigi in his quest to assemble the Marvelous Compass during the events of Paper Mario: The Thousand-Year Door. Before joining Luigi, Torque lived on Circuit Break Island, the home of extreme kart racing.
Differing in appearance from a regular Spike Top, Torque has a green shell, and instead of a spike, Torque's has a wrench. Apparently, Torque has the ability to attach a variety of different tools to his shell, and as such, he became a mechanic of go-karts.
When Luigi arrived on Circuit Break Island, he discovered that the champion of the kart races would earn a trophy with a piece of the Marvelous Compass embedded in the plaque. Luigi claims that he entered the contest and was paired with Torque. Together, they won the race and earned the piece of the Marvelous Compass. In reality, however, at the beginning of the race, Luigi accidentally went in reverse, destroying all the karts in the competition (and thus winning the race). Torque decides to tag along with Luigi until the plumber can pay him back for all the damage he caused on the island. It is not known if he gets his money back.
