Astro Boy Episode 10

Koichi has a super robot car White Planet, which was made by his late father, and he and his sister Mitsuko are preparing toward their 6th straight victory at the annual car race circling the equator. But White Planet is destroyed by Skunk who plans to stop their victory.
Dr. Ochanomizu pours all his energy into repairing the car; however, there is only one part he is not able to repair --the electronic brain of the car. Then, Dr. Ochanomizu comes up with the idea to use Atom's excellent brain as a replacement.
Finally, the Annual Car Race has come. Among several cars, Black Devil driven by Skunk's men Kiel is also seen. White Planet has appeared just before the race starts. Koichi tries to locate Mitsuko among the audience, but he is not able to find her and feels uneasy.
The race has started. At the early stage of the race, White Planet is a little behind since being involved in the accident. But Koichi almost catches up on the car driving top with his superb driving techniques.
While the race is going on, Skunk destroys Telecast Tracing Satellite 194 and tries to attack White Planet by an atomic submarine Sea Dragon. But his plan is blocked by somebody. Then, White Planet is attacked again by a huge octopus off the east coast of Africa, which is also a robot dispatched by Skunk. Then, Atom appears and defeats the robot octopus.
The secret of White Planet is that Koichi's father prepared a spare electronic brain when he made the car and made Michiko using the brain. In fact, it was Michiko's brain used for the repair but Atom's. The truth is Atom has been on a secret mission to guard White Planet.
