Brains is chief engineer of International Rescue and creator of the Thunderbirds craft.
Born in Michigan on November 14, 2040, the young genius lost his parents due to a freak storm when he was 12 years old. He was then adopted by a Cambridge professor who allowed his brilliant mind to develop even further.
Jeff Tracy found Brains shortly after IR's conception at a small cultural hall in Paris, he realised his genius would be vital, and Brains accepted the job wholeheartedly. He developed the many vehicles that help get many of the jobs done.
Brains never stops living up to his nickname. His favourite hobbies include mathematics, especially trigonometry, as well as developing other machines, such as his intelligent robot, Braman, and vehicles for outside companies, such as Skythrust and Skyship One.
