Dr. Tenma (天馬博士, Tenma-hakase^?), whose real name is Umatarō Tenma (天馬午太郎, Tenma Umatarō^?) and is also known as Dr. Nagamiya Tenma, Dr. Boynton, and Dr. Balthus, is the father/creator of Astro Boy in the anime and manga series of the same name created and animated by Osamu Tezuka.

Tenma means Pegasus and is literally translated from Japanese as Heaven-horse.

Tenma was a renowned roboticist and the Japanese Minister of Science, who was described by Tezuka in Volume 7 of the manga this way:

Tenma appears several times in Astro Boy adventures. He has slightly different roles in each series.

When Tenma's nine-year-old son Tobio dies in a car accident, he decides to recreate him as an invincible robot. After living happily for a while with the child robot, Tenma realizes that an artificial child can not replace his son, particularly when he acknowledges that the robot will not grow like a normal child. So, he sells the robot to Hamegg, a robot salesman. The robot eventually ends up performing in a circus. It is here where he is found and adopted by Professor Ochanomizu, who turns him into Astro Boy.

Tenma realizes that Astro is amazing and, even though his affection towards the robot begins to return, he knows he can never make amends for his behavior. Still, he helps Astro frequently. He builds robotic parents for Astro, enhances Astro's power to one million horsepower (700 MW) when he fights Pluto, rescues Astro from a Cleopatra robot, and rebuilds Astro after he is destroyed while trying to protect Blue Knight.
