"Nothing's impossible with science!"

Hiram Hackenbacker, better known by his codename Brains, is a character from the Thunderbirds Are Go! television series. He is a unique and vital member of International Rescue, since he is the man who designed most, if not all, of the organisation's high-tech vehicles and equipment, including the entire Thunderbird fleet. He may well be one of the most intelligent people in the world, and the Tracys are lucky to have him as part of the family, even if he isn't literally a part of the family.

Personality and TraitsEdit

Brains has been shown to be highly educated in history, geography, mathematics, physics, mechanics, information technology, and many other subjects, and his general knowledge is through the roof. The Indian man has also mastered the English language, so simply put, he is an absolute genius and he always acts like it with his constant inventing. He is a workaholic who over-complicates every single thing he does; ask him to do something as simple as make biscuits, and he'll use an infra-red chamber like he did in Skyhook. He is also quite the perfectionist, and he can often be found making various modifications to the Thunderbird fleet. His knowledge means he can always be relied on by the brothers when they are not sure of what something is or when they don't know what they should do during a rescue. He also contributed to the creation of the Fireflash airliner, so he doesn't just invent things for use by IR.

All this being said, it's not like all of his inventions work; He nearly broke his neck after testing his suction shoes, which were designed to allow the wearer to walk on ceilings. He is also so nervous and timid, that he would much rather stay on Tracy Island and help the brothers from there rather than actually go with them to the danger zone and get directly involved with the action. He will only come with them if it is absolutely necessary like it was in the episode Runaway; where he puked right after taking off and screamed and rambled like a madman when attempting to board the vehicle in distress via riding down Thunderbird 1's cable. However, he managed to save the day in despite all the pressure he was in.


Main article: /Missions

Brains features in quite a lot of episodes as a major and minor character. There are three in particular where Brains is the central character.


A high speed train is out of control in Japan and after Brains tried to tell Scott how easy it is to fix, Scott makes Brains go along on the mission to help him stop the train.

Heavy MetalEdit

When Brains' old university friend Professor Moffat wants to show him the new Supreme Hadron Collider in Switzerland, Alan flies him out to check it out. After activating the Collider however, the Gravity right above the science lab becomes a 'gravity well' which begins to bring down anything within range crashing down to earth.

Lost KingdomEdit

After a seaquake near the coast of Greece reveals the lost city of Atlantis, Francois Lemaire ignores International Rescue's warning about aftershocks and with his wife, Madeline, venture below the depths to explore the area. When their submarine becomes stuck, Virgil and Gordon are called to assist. Brains and MAX go with them so that they could see the Solar Kythera, an ancient device used to view the stars.



  • For a 'modern' audience, Brains has undergone a racial change, though he still resembles his 'classic' counterpart with his large forehead and big blue glasses. The change was first revealed by voice actor Kayvan Novak, who openly confirmed in early 2014 that the producers wanted an 'Asian Brains'.
  • Professor Moffat refers to Brains as "Hiram" in Heavy Metal. In the classic episode Alias Mr. Hackenbacker it was the original Brains' alias.
  • Moffat is not only an old Cambridge University friend of Brain's but also his romantic love interest, as seen in Heist Society.
  • He is one of the 4 known members of the organisation who aren't biologically related to the Tracy family; the others being Kayo, Parker and Lady Penelope.
  • Like the original, Brains stutters but to a much lesser extent.
  • He is revealed that he is an old colleague of Professor Langstrom Fischler in Skyhook. He claimed that Fischler never focused on safety with his inventions, completely unlike himself.
  • In Earthbreaker the Mechanic seems to know Brains, however Brains has no idea who the Mechanic is. Brains is slightly confused as to how this can be possible when they haven't even met. Later, in Home on the Range, when the Mechanic met Brains, the Mechanic recognized Brains immediately.
