Most beings in the multiverse belonged to one of two sexes, male or female. However, some species could adopt the sexual characteristics of either sex, and were classified as hermaphrodites. Other variable species, like the X'Ting, changed sexes periodically based on hormonal cycles. Some alien species had more than two sexes (the insectoid Xi'Dec had over 180 different sexes. Finally, some species, like the Filordi, were asexual, with individuals being able to reproduce on their own. The Fnessian race had a previously undocumented sex called Thos. The Rakririans also had a third sex, known as facilitator drones.
