Ep 20. Return of Cleopatra

That fiend of the Nile, the evil genius Rasburton, had once before confronted Astro Boy, then fled when the brave, little robot thwarted his scheme to re-create an Egyptian dynasty. Now he returns with a regal queen whom he calls the new Cleopatra. She is the ancient beauty reborn, he insists, and with the aid of strong-arm tactics, he installs her as Queen of the Nile. Astro Boy, sensing trouble, arrives to investigate, but he is surprised and ambushed by a colossal robot that stuns him and leaves him to perish in the desert. All seems lost until a handsome young sheik discovers the disabled Astro Boy and revives him. Cleopatra is a fake, reveals the sheik a sham, a mere robot built by Rasburton to resemble the Cleopatra of old. Actually, Rasburton is now ruler of the Nile - a cruel pharaoh who seeks to make all the people his slaves. Astro Boy needs hear no more. He swings into action at once, engaging in a mighty battle with a robot that towers higher than the ancient Lighthouse of Alexandria! Rasburton is defeated but, oddly enough, defeated only indirectly by Astro Boy. For the evil genius' own robot turns against him and makes it impossible for Rasburton ever to return!
