This is a list of episodes from Captain Simian & the Space Monkeys, an American animated television series which premiered on September 7, 1996, and ended after 26 episodes on June 21, 1997.
Most of the episodes were aired out of order. The episodes are listed below in the order of intended airing.
The crew answers a distress call from the NC-17 galaxy, where they find a derelict ship and split up to search it. Spydor uses his beamatron to pick up a pile of crystals. The crew then returns to their own ship, since they didn't find anyone alive, and also because Splitzy started a core meltdown. On their way out, Spydor uses the beamatron again to pick up an egg (which he thinks is a coconut).
Later, an alien hatches from the egg, attaches itself to Spydor's rear end, then escapes into the vents. The alien spits out radioactive mucus. By the time the crew finds it again, it has grown, and dodges their blasts. Splitzy says that the alien's DNA is changing rapidly, allowing it to change shape quickly; as Gor-illa fights the alien, it absorbs his DNA, reconstructing itself and becoming stronger.
The ship is warped to a planet in another galaxy, where they are attacked by a missile (labeled "USA") and several unmanned planes. After blowing up the planes, they search the planet further, finding that it looks like Earth but is covered entirely with jungle, and meet an intelligent monkey named Lilith. Lilith identifies herself as the caretaker of the planet, and tells them that an alien race recently visited, got rid of all poverty and pollution, and made all species intelligent. The others all left to explore space, leaving her behind as the chosen caretaker. Captain Simian quickly falls for her, and she takes him to look around.
The rest of the crew continue to search the planet separately. Gor-illa, Spydor, and Splitzy are attacked and captured by living vines. This turns out to be the work of Rhesus 2, who then confronts Captain Simian. Rhesus 2 explains that the planet isn't Earth, but his former homeworld Terrestria; long ago, its human scientists sent him into space, but his pod escaped orbit and was beamed on board by Lord Nebula, who made him intelligent. After their previous encounter, the immortal Nebula brought Rhesus 2 back to life and sent him searching for a substance called Uterium, which would allow Nebula to become a black hole once again. To this end, Rhesus 2 enslaved his homeworld; he attaches some of his brains to the crew, mind-controlling them so that they cannot escape, and adds them to the slave force.
