Umataro Tenma

Doctor Umataro Tenma is a brilliant roboticist, ex-minister of science, husband to Hoshie Tenma, and father of the late Tobio Tenma. In the 2009 animated movie "Astro Boy", he tells his robot servant Orrin to call him Bill, which is supposedly his first name, disagreeing with all previous manga. He plays integral roles in all version especialy the '03 anime and manga. He created Astro Boy to replace Tobio after he died in an accident. His fate in some versions includes, lurking in the shadows to keep an eye on the last thing he cares about in the world, Astro, but never revealing himself because he is too ashamed of his past behavior (manga), selling him to the circus and forgetting him (original anime), disowning Astro and later dying of a heart attack (1980s anime), or maniacally forcing Astro to become the overlord of a world ruled by robots against his will by making him evolve (2003 anime).

Tenma's role in the 2003 series is pulled mainly from the manga chapters "Astro Reborn" and "Melanin Tribe" where it is revealed to the readers that he is not just a mean man, but rather a wicked one bent on controlling Atom. He does redeem himself however in "Meeva".

He was voiced by Nicholas Cage in the '09 movie, with an entirely different character.

Robots he created:

Shadow
