Cybele (Lindsay Duncan) – An AI that knows Caleb and about his past, and is Caleb's only ally apart from recruits. It's later revealed in series 2 that Cybele is the AI of Laura Gant, Caleb's mother that died many years ago from the same unknown disease that Caleb caught. Neuros (Lindsay Duncan) – The main computer system controlling all the Roboidz, who takes the appearance of a brain in a bio-rod-like container. In the series 2 finale, it's heavily hinted that she is the brain of Laura, thus being Caleb's true mother. Roboidz (voiced by Gareth Jones, Rich Garraghty & Noel Byrne) – The Roboidz are robots that were originally created by Laura Gant and Simon Lansing to aid humanity. But, due to a revolt on Gamma FI4, turned against their creators and all but destroyed mankind. They were powered down in every place at the end of series 1, but reactivated by their leader, Arkon. They come in different classes, each a different colour and wielding different weaponry: Guard (Commander Class) – They are silver in colour and, although they have no visual ability, have the latest radar tech. They are also the most intelligent of the Roboidz and armed with multi-digit claws which are more powerful than steel and can be fatal to a recruit Worker (Drone Class) – They are yellow with black stripes and do all the menial jobs around Future Gate, armed with the strength of ten men and pincer claws which can destroy anything, particularly Caleb's recruits. Luckily for the recruits, they are the least intelligent of the Roboidz. Wardroid (Battle Class) – They are red in colour and are the police force of Future Gate, armed with military training, a vector-beam rifle, and boxing glove-like rip claws. Despite being the most dangerous of the Roboidz, as Caleb describes them, they are "pretty stupid." Arkon (Peter Dickson) – Led all the Roboidz to earth after the Gamma FI4 revolt and seemingly died at the end of series 1, but was shown to be alive as he powered up all the Roboidz again (including himself and Neuros). Unlike the other Roboidz, he has blue eye lights, a blue colour scheme, and the ability of speech. Shades (voiced by Gareth Jones, Rich Garraghty & Noel Byrne) – They used to be people before the Roboidz converted them into foul-smelling, inhuman slaves to carry out the
