Shadow



Shadow is a robotic scientist who was created and designed by Dr. Tenma. After Dr. Tenma created Atlas, he realised that humans don't evolve as fast as robots, and therefore couldn't create robots as powerful. So he created Shadow, a "robot that creates robots".

Shadow also creates these robots to fight Astro and force him to evolve until Astro became the most powerful robot in the whole entire world. Shadow wears hooded clothing so it's impossible to see his face, but at one point he takes his hood off revealing a robotic face with yellow eyes. Shadow was the creator of Pluto and Acheron.

He is also the leader of Robotonia.

== Other Appearances ==

Shadow is exclusive to Astro Boy '03 and appears in no other Tezuka works. However, he makes a cameo appearance in Astro Boy: The Omega Factor as Sharaku's alter ego.
