Horatio Hackenbacker, better known by the nickname "Brains", was a scientist and member of International Rescue.
In June 2066, he was awarded the four million dollar Unity City Prize. His Presidential Citation mentioned some of his work with Robot CCD, the World Senate computer control decider, which was used to check senate decisions. (PROSE: Space Hi-Jack)
During the heat crisis, Brains went up with Alan to Thunderbird 5 in order to investigate the phenomenon in greater detail. He found solidified space debris travelling at tremendous speeds on a collision course with the Moon. He inspected the meteorites upon landing on the Moon and determined them to have escaped from the Sun, recommending a close observation of its surface to Jeff as well as liasing with the World Government to find a solution. After Jeff persuaded World President Nikita Bandranaik to agree to the plan, Brains and Alan set off in Thunderbird 3 to photograph the Sun from within gravity limits to gauge its future activity. Upon reaching their destination, one of the booster rockets failed as they fell into the Sun's gravity field but Alan was able to get it working before the temperature rose too much and, after taking their pictures, they returned to Earth.
Carrying a platomic missile to destroy the new satellite the Sun was about to produce, as well as extra isotope circuits to ensure their escape speed from the Sun's gravity, Brains and Alan boarded TB 3 bound for the Sun yet again. However, Brains had miscalculated how much time they had left and Alan was forced to use the isotopes before even reaching the Sun, with Brains proclaiming "It's us or the world!".
