A superorganism was an organized society of living beings that functioned as a large singular organism. On Earth, colonies of creatures such as ants and bees were considered superorganisms.
In 2383, a group of cilium-like vegetation that Zero identified as a superorganism inhabited a dangerous M class planet known as the Murder Planet. They possessed telepathy and operated in a similar manner to a telepathic pitcher plant to attract their prey. (PRO: "Dream Catcher")
