Shadow



Shadow is arobot who was created and designed by Dr. Tenma. After Dr. Tenma created Atlas, he came to a point where he could only go so far when it came to creating advanced robots. So he created Shadow, and programmed him to built and design powerful robots that would seek out and destroy other 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 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.
