The Searchers meet a colony of Astros who hate humans. Their leader, Captain Astro, refuses to listen when Genki explains that not all humans are bad, and he explains why he feels this way. The ancient people of Pangea ran out of resources and forced the Astros to look for more, working them well past their breaking points. Many of the Astros died, and now the Captain accuses humans of being evil and destructive.
Genki tells him that not all humans are like that, but he won't listen...until Genki risks everything to save his life as they're about to go down a waterfall. With Suezo's grip on them weakening, Astro shoots his rocket fist to save Genki, finally realizing not all humans are bad. Captain Astro meets with his troops and tells them to call off their war on the humans, asking that they try to enjoy their freedom... and then dies.
