Humanoid species that abducted humans from Earth many years ago to use as slave labor on their new colonies. The plan backfired when the humans rebelled, enslaving the Skagarans. The humans implemented laws preventing Skagarans from owning property, being educated and marrying. Skagarans were often referred to with the derisive term "Skags." A visit from the crew of the Enterprise enlightened the human population, and the outdated laws were soon changed for the better.
