Collectors

Beta Quadrant species that, as their name implies, collect items from worlds they encounter. A Collector Vault-Ship, which is a massive vessel made up of a line of five large black spheres, will enter orbit above a world and send in smaller ships and foot soldiers. Many of the soldiers are actually members of other species that have been collected and fitted with mind-control helmets. The Federation first encountered the Collectors on the planet of Falinor. The Collectors had swarmed in, assessed the planet's property, collected what was of value to them, and then was in the process of liquidating the rest in a massive sale when the USS Wayward intervened. The Wayward crew were able to run off the Collectors. (Everything Must Go! [WAY])
