Buzz Lightyear of Star Command - Season 1 Episode 45

Ship 42 scopes out area where ships have vanished. Upon scanning the planet, they detect large amounts of technology on the planet, but upon landing it seems quite barren. Flying manta-like shriekers attack Team Lightyear's technology, leaving them stranded and defenseless. Roaming the countryside, they encounter a man named Flint who runs a town of castaways from spaceship-wrecks. Upon investigation, Flint turns out to be a renegade work robot (gamma series construction robot), who built the robotic shriekers in order to strand organics on the planet, so that he could order THEM around as revenge for his time spent in forced labor (...as a stock-boy...). Team Lightyear shut down the subterranean shrieker construction plant that Flint had built, and defeat Flint, freeing the hapless castaways.
