    Born to wealthy industrialist Tomeo Takachiho and Maemi Takachiho, Hiro was raised in the affluent Tokyo suburb of Yoga, City of Setagaya. His parents noticed his intellectual brilliance at an early age, and he was placed in pre-school at age 2. He was eventually recognized as one of the world's most brilliant child prodigies and was accepted into the prestigious private Tesuka Advanced Science Institute. It was at the Tesuka Institute that young Hiro's proficiency for invention and innovation was discovered. He created his first and greatest invention to date, the robotic synthformer known as Monster Baymax, as a project for the Institute's science fair.


    Hiro Takachiho was created by Scott Lobdell and Gus Vazquez in 1998 and first appeared in Sunfire & Big Hero 6 # 1.

    At age 13, Hiro was targeted by the Giri, a top-secret consortium of Japanese politicians and business entities that was established to recruit and train potential operatives for a Japanese super-team, Big Hero 6. Silver Samurai (Kenuichio Harada), Big Hero 6's initial field leader, first approached Hiro's mother for permission to have him join the team, but she refused due to her desire for her child to live a normal life Silver Samurai then approached Hiro directly, but the boy was less than impressed with Big Hero 6. However, after his mother was abducted by the Everwraith, the astral embodiment of all those killed in the 1945 nuclear attacks on Hiroshima and Nagasaki, Hiro was forced to turn to Big Hero 6 for assistance. After joining forces with the team, which also included his idol, the Japanese hero Sunfire, Hiro opted to join the team and has remained a member ever since. In fact, when Silver Samurai and Sunfire left the Big Hero 6, Hiro was appointed to serve as the team's field leader. He continues to maintain a civilian life and attend classes at the Tesuka Institute, although his teachers and classmates are unaware that he moonlights as a secret agent.


    Hiro is a brilliant child prodigy, proficient in many fields of science and technology, with a focus on biology, physics, and robotics. Although he is only an adolescent, he is a visionary theoretician and accomplished machinesmith who has already made several breakthroughs in fields such as robotics, computer science, synthetic polymers, geology, biology, and communications. He is also a gifted tactician and strategist.

    Hiro has constructed several robots, his first and most advanced creation being Monster Baymax, a water-powered synthformer whose artificial intelligence is based on the thoughts and memories of his departed father. Other notable inventions include: the Bio-Atomic Parcel Detector (B-APD), a device capable of pinpointing the location of human-sized nuclear reactors; a jet-pack-propelled flight suit that grants its user limited firepower capabilities; a holographic virtual reality projector that can produce a comprehensive recreation of previous events by amassing information from various data streams; and eye glasses with a cybernetic video display that can connect to an assortment of computer networks. Many of Hiro's inventions (including Monster Baymax) are connected to his Core Cyber Network (CCN), a mobile personal area computer network used for communication among his many mechanical devices.
