Artificial
From Tardis Wiki, the free Doctor Who reference
Artificials, also known as Breeds, were a genetic clone race, vat grown and stored by humans for the purpose of maintaining 374926-slash-GN66 and protecting its cargo. (PROSE: Star-Crossed)
Behind the scenes
The Artificials share numerous similarities with the Gangers in TV: The Rebel Flesh / The Almost People.
Firstly, they are made from similar material to the Flesh, which uses the DNA of the original crew to form duplicate bodies. The crew treats the Artificials as a lesser species and only see them as slaves. When their work is completed, the Artificials are reduced back to their Flesh-like liquid and new Artificials are made.
