Astro Boy: Tetsuwan Atom - episode 46 - 28 Feb, 2004

The Blue Knight, who has parted ways with the humans, and the robots who have followed him, gather in Antarctica. There, the Blue Knight declares that this place will be named Robotania. When the humans learned of this, they misunderstood that the robots had rebelled against the humans, and began to look at Atom with fear. Finally, a decision is made to dismantle all the AI robots, including Atom. Ochanomizu, who opposes the decision, is considered an enemy of humanity. Inspector Tawashi has no choice but to capture Atom and the other robots because of the orders issued to him, but Ochanomizu secretly lets Atom go. He entrusts everything to Atom, saying that he is the only one who can go to Antarctica to meet the Blue Knight and save the future of robots and humans. When Ena finally regains consciousness, she is baffled by the fact that she was supposedly thrown down the stairs by Kipp, and by the commotion that followed. (Source: Wikipedia)
