President Stone

President Stone or simply Stone is the main antagonist in the film.

In the film he built a robot called to defend the city from an attack from the surface, despite the fact no indication has ever been made that they would do so. The blue core was prepped for the robot but Stone, who had heard the blue core was essentially a manifestation of peace and life instead chose the negative Red Core.

He had millions of soldiers resembling clone troopers from Star Wars: The Clone Wars.

Later on he flew a Command Ship. His troops and his right-hand man got a radar signal of the Blue Core. He sent Stinger Interceptors to capture it.

He brought his command airship called The Spirit of Freedom. Similar to a fire-breathing dragon, he tried to destroy the robot, but failed.

He later went to Dr. Tenma's apartment to arrest Tenma. He later releases him.

He brought his dropship to capture Astro and take him to the Ministry of Science to be deactivated. But Astro was later reactivated.

He failed to capture him, he later activated the robot, but the robot ate it.

He survived the destruction, but was kicked by a girl and arrested by his men after it was destroyed. Due to that, he was arrested by his troops. The people of Metro City told the soldiers that Stone was mean due to destroying the city.

After he was captured, they elected a new and better president called Logan.

It was unknown that he was shot by his troops.
