1	-	"The Birth of Atom" "ATOMU tanjō" (Japanese: アトム誕生)	October 1, 1980 (1980-10-01)	-
Doctor Boynton is a robotics engineer struggling for a breakthrough, while his son Toby longs for his affection. One night, a shady criminal, Skunk Kusai, visits his home and offers Dr. Boynton a new circuit known as the Omega Factor, which would allow robots to become far more human-like, to the point of defying all Laws of Robotics. Boynton angrily throws him out of his home. Toby, having overheard their conversation, suggests to his father that he design a new robot that resembles a human boy. Boynton is inspired by this, and creates a new template for this design. However, he neglects his promise to spend time with Toby at an amusement park, hurting Toby's feelings. As Toby leaves the park, he is caught in a traffic collision and is horribly injured, and dies from his wounds in the hospital; before this, he has his father promise him to make the robot in his image and treat it like his own. Overcome with grief, Boynton completes the project, christening the new robot after his deceased son, and brings him to life. However, Skunk has copied the template designs as well, and takes them to a scientist named Walpurgis, who builds a robot he names Atlas. Boynton takes the robot Toby home, teaching him about life and how to live like a little boy. However, some time later Toby becomes paralyzed, his eyes blinking red, and disappears from Boynton's home. Boynton and his colleagues track Toby down using a robot tank, but the tank suddenly goes berserk with them inside, causing Toby to rush to save his father and his colleagues. Little do they realize that Toby's behavior was caused when Atlas was activated; the two robots had "called" one another. Later, in the hospital, Boynton tells Toby that he is very proud of him, but since he was no longer a secret, the two would have to leave the country for a while. Atlas and Walpurgis' robot maid, Livian, discuss his purpose, with Atlas uncertain of what lies ahead for him.

Dr. Boynton and Toby depart on an ocean liner for America, but Toby is unintentionally destructive, as he doesn't realize his own strength at times. Frustrated, Dr. Boynton has him stay in their cabin while he heads for dinner. However, a couple of guests want to meet Toby, so he has no choice but to bring him along. During the dinner, the guests realize that Toby is a robot, and even though he means no harm, manages to ruin the dinner by tipping the table over, causing a huge mess. Angrily, Boynton rejects Toby on the spot, declaring that he's just a robot and that he has no son. Meanwhile, Skunk Kusai has taken to educating Atlas in crime, teaching him how to rob armored trucks. Atlas, however, destroys the trucks before robbing them. Skunk then tries to teach him how to rob a supermarket, but Atlas, instead of stealing money, makes off with receipts instead. Frustrated with his incompetence, Skunk tells Walpurgis that Atlas is a fool and the Omega Factor has done nothing for him, but Walpurgis counters that Atlas is becoming more humanlike, and mistakes are a human factor in learning. Atlas, meanwhile, is consoled by Livian, who begs him not to follow a life of crime, but Atlas insists that he become more human to impress Walpurgis. Livian tells Atlas that a man must not harm those weaker than he, and even though they are robots, they also identify by gender. Atlas asks if Livian can be like his mother, as she is the only one who truly makes him happy. However, Skunk interrupts their talk to take Atlas on a mission. As Toby considers what Boynton said to him, he is approached by a shady circus owner, Hamegg, who asks if he would like to join the circus now that he had been disowned by Boynton. He takes Toby with him and coerces him into signing a contract, declaring Toby Hamegg's property. Meanwhile, Skunk tells Atlas that he plans to sink the ocean liner and have Atlas go in and steal a haul of gold bars on board. His plan is to create a field of icebergs in the path of the ship to cause it to crash. Setting off explosives, he creates a large flow of icebergs, but Toby manages to destroy the icebergs by breaking them up, saving the ship. He encounters Atlas, who attacks him and nearly destroys him until he recalls Livian's words. In a show of mercy, Atlas leaves Toby on the ship's deck, where he hears Boynton, who feels remorse for what he has done, calling out in desperation for him. However, he is found by Hamegg first, who grabs him and stuffs him in a crate. Atlas returns to Walpurgis' castle, where he finds that Walpurgis has dismantled Livian as punishment for her accidentally destroying a gargoyle sculpture. In a fit of rage, he attacks Walpurgis, who escapes by car. Atlas chases him, and even though he is severely damaged by missiles from the car, manages to catch him and run him off the road, apparently killing Walpurgis. Atlas returns to the lab and uses Walpurgis' equipment to begin rebuilding his body.

In Astro's second encounter with Atlas, he stops Atlas's scheme of enslaving humanity by a series of technological thefts, one of which involves the proposed robotic mother and father for Astro. Note: This episode's title does not make sense in the context of the English dub as Atlas had not made an appearance in the series yet due to the combining of episodes 1 and 2. Astro's encounter with Atlas also doesn’t make sense as Astro recalls the fight they had on the iceberg, refers to Atlas by name and recognises him despite having not been shown meeting. There is also no proper explanation for Atlas’ change in appearance in the flashbacks and the present time. It could be argued that the events of Astro vs Atlas that were cut out still happened, albeit off screen.

The Robot Viking leader attempts to kill Astro by flooding the cavern with lava, but Astro escapes with Livian, while the Robot Vikings die in the lava.

One evening, Astro is watching a story on TV about a boy who finds a bottle that contains a genie, who is released and promptly threatens to eat the boy. The boy instead asks to see if the genie can drink all the water in the sea; the genie grants his wish and drinks so much water that he explodes. As the story ends, a large meteor falls into a mountain valley some distance away. Dr. Elefun, Astro, and a team of scientists head off to investigate the crash. At the impact site, Astro uncovers a large metallic meteor-like object that turns out to be a mass of metal parts. Astro constructs the parts, and finds that they form a giant robot. A message capsule hidden in the mass calls the robot "Garon", which came from an alien planet and apparently has terraforming abilities. That night, a thunderstorm erupts, and Garon is brought to life by a stray bolt of lightning, frightening the scientists. Astro subdues Garon before he can cause damage, trapping him back in the impact site and buried in molten lava. However, one of the scientists, Dr. Adams, later uncovers Garon and secretly smuggles him to a remote island in the South Pacific. There, he requests Garon terraform the island to resemble the planet of his origin. As Garon proceeds to terraform the island, he also alters the atmosphere around the island to that of his planet. The scientists discover that his atmosphere has almost no oxygen content, but all perish before they can escape. The tradewinds begin carrying the poisonous atmosphere across the South Pacific, killing all life in its way. Astro is sent by Elefun to investigate, and he encounters Garon, still busily terraforming the island. Realizing that he can't win by brute force alone, he tricks Garon into also altering the gravity of the island to match that of his planet for at least one minute. Garon falls for his trick, and after altering the gravity of the island, gets shot back out into outer space, creating a vacuum around the island that pulls all of the poisonous gas along with him.

Alien invaders arrive in the Sol system and begin destroying space stations orbiting several of the planets. The nations of the world believe the attacks are those of Atlas, and unite to form a World Defense Force to stop Atlas. Captain Keeley, one of the squad leaders, is tasked to destroy Atlas, which he desires as revenge for the death of his brother, a scientist on one of the destroyed stations. Astro, however, wishes to reason with Atlas, but Keeley refuses and takes his squadron out to battle. Atlas arrives to battle Keeley's squadron, and when Astro confronts him about the attacks, Atlas claims he never attacked the stations; he had come because he had heard the humans were seeking him out. He instead decides to battle Astro instead, but Livian, who was watching their encounter, begs Astro not to fight Atlas, as the two are actually brothers; Atlas and Astro were born of the same template. Astro is shocked, and Atlas goads him into joining him, knowing the truth, but Astro can't bring himself to do so. Astro has a flashback of all of their previous encounters, and he begs Atlas to make the right choice. Keeley finds Astro, and reveals his key weapon: a laser that can damage Atlas's Omega Factor. Astro rushes to find Atlas to warn him about Keeley, but Atlas refuses to run; Keeley finds Atlas and shoots him with the laser, despite Astro's begging him not to. The invaders reveal themselves, and destroy most of Keeley's squadron. Back on Earth, Dr. Elefun studies the footage of the invaders, deducing that Atlas was telling the truth. Astro tells him that he and Atlas are brothers; Dr. Elefun recalls the theft of Astro's plans and realizes Astro is correct. Meanwhile, the WDF calls an emergency meeting to strategize a plan on stopping the invaders, who are heading straight for Earth. Keeley's squadron rush back to Earth, and Astro rushes to the rescue of many civilians until he collapses from energy exhaustion. He is found and brought to an emergency shelter with Elefun. Keeley contacts him and tells him that an invader squadron is coming from Saturn, and he confesses he was wrong about Atlas. Astro swears that he will protect all those that he knows and loves, and rushes to find Atlas to reason with him again. He gets ambushed by invaders, but Atlas finds him. Astro begs Atlas to help the humans fight the invaders, but Atlas stubbornly refuses, claiming he hopes all of the humans die. Astro rebuffs him by saying that not all humans are bad, and that many are good and kind, and see past Astro being a robot. Livian reasons with Atlas, saying that Astro fights out of love and not out of hatred, but Atlas thinks he is foolish. He tells Astro to tell the humans "Perish!", but Livian shows Atlas the battle between Keeley's squadron and the invaders. Keeley sacrifices himself to destroy several invaders, and Atlas joins the fray, destroying many more invaders. They find the invader's base, and Atlas warns Astro not to join, and tells him that they are truly brothers after all. Livian stays with Atlas, out of love, and the two give their lives to pull the entire base and the invader squadron out into deep space. Astro is heartbroken by his brother's sacrifice.

In a prologue, Astro Boy's creator Osamu Tezuka reveals a little secret about the robot boy: That his legs are actually those of a robot girl. The backstory behind this fact, the plot of this episode, is that Astro Boy is tasked to retrieve one of his own blueprint templates from a military fortress of the Grota Republic. He meets and bonds with Nuka (Nikki in the American dub), a sentient robot girl built from his very template, which unfortunately incorporates a neutron bomb, and in order to stop the bomb, the two robot children have to make a costly sacrifice: she must be completely dismantled in order to stop the bomb. Astro, having fallen in love with Nikki, stays with her till the very end. All that is left of her are her legs, which Astro takes to Dr. Elefun and asks him to switch his legs with hers, so that she could be a part of him forever. Elefun fulfills his request, and Astro happily takes off on more adventures.
