Tetsuwan Atom (1980) - episode 5 - 28 Oct, 1980

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 that this episodes 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. Astros 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 scene.) (Source: Wikipedia)
