CyberNomad

The CyberNomads, or simply Nomads, were a Cyber-subspecies identified by ArcHivist Hegelia.

A group of nomadic Cybermen, they were one of two distinct groups which broke away from the CyberFaction of Planet 14, itself an offshot of the original CyberMondasians. Whilst the other group settled on the planet Telos, becoming CyberTelosians, the Nomads proliferated throughout the galaxy of Mutter's Spiral. Following a devastating war with the Vogans, Hegelia believed that a group of CyberNomads survived near-extinction and came across Telos, where they combined their Cyber-technology with the Telosians to form a single, new Cyber-subspcies, the CyberNeomorphs. (PROSE: Killing Ground, AUDIO: The Early Cybermen, The Cyber Nomads)

Vulnerabilities
The most notable weakness of the Cybermen was the element gold which, being non-corrosive, choked their respiratory systems, a property exploited by the glittergun used during the Cyber-Wars. (TV: Revenge of the Cybermen) Gold also blocked their sensors and caused cybermats to malfunction. (PROSE: The Revenge of the Cybermen)

Hierarchy
CyberNomads were typically led by Cyber-Leaders who were distinguished by black Cyber-helmets. (TV: Revenge of the Cybermen)

Weaponry
The CyberNomads had their weapons built into their Cyber-helmets. Like other Cybermen, they had portable cyber-bombs capable of devastating a planet. They also made use of Cybermats, which were made to spread viruses amongst humanoids. (TV: Revenge of the Cybermen)

Origin
According to the ArcHivist Hegelia, the CyberNomads were the Cybermen who travelled out into Mutter's Spiral from Planet 14, a planet which had been used as a base by the Cybermen during numerous attempted invasions of Earth following the destruction of Mondas. (PROSE: Killing Ground)

Early history
Hegelia suggested that the CyberNomads had spent roughly two hundred years, from around 1990 to 2190, proliferating throughout Mutter's Spiral. (AUDIO: The Cyber Nomads)

The Ninth Doctor, accompanied by Rose Tyler, found that a Nomad's Cyber-helmet was among the exhibits on display within Henry van Statten's vault in 2012. (TV: Dalek) Years later, Adam Mitchell used the Cyber-helmet to send out a sub-ether signal in order to lure out a Time Agent. (COMIC: Mystery Date)

22nd century
By the 2150s, the CyberNomads were involved in a war with Voga. In order to expand their numbers, the Nomads invaded the human colony Agora and used the threat of total destruction to turn the planet into a self-renewing source of physically healthy humans. For the next few decades, the Nomads returned to Agora every three years to collect 500 ready-to-convert humans. (PROSE: Killing Ground)

In 2176, the Cybermen stopped an attempted rebellion on Agora. (PROSE: Killing Ground)

The Cybermen eventually managed to destroy most of Voga, (TV: Revenge of the Cybermen) but not without severely weakening themselves. At this time, the Nomads had more organic components than any other previous model except the original Mondans. They were forced to use a stolen Selachian ship as their ship.

When a small party of Cybermen came to Agora in 2191, they were destroyed by cybernetic warriors created by the Agorans using Cybertechnology. The main Cyber ship came to Agora to destroy the rebellion, but instead it was infiltrated by the Sixth Doctor and flooded with radiation which killed the Cybermen.

By the end of the 22nd century, the Cybermen were believed to be extinct. In actuality, most of the Cybermen were hibernating on Telos. A few small, isolated groups still existed. (PROSE: Killing Ground)

Later history
During the 2260s, a group of CyberNomads, led by a Cyber-Leader, made an incursion into the Federation universe, where they infiltrated a Federation facility on the planet Aprilia III. They mind-controlled the researchers, making them unemotional and docile. The USS Enterprise was sent to investigate on stardate 3368.5. Captain James T. Kirk, Mister Spock, Doctor Leonard McCoy and Lieutenant Commander Montgomery Scott travelled to the planet's surface in the shuttlecraft Galileo, they were later interrupted by the Fourth Doctor, who was visiting the planet in his TARDIS. He helped them break the lock and together they infiltrated the facility. There, they discovered the archaeologists under the control of the Cybermen and tried to free them. A battle ensued and the Cybermen were destroyed with the Doctor's aid, while the researchers were liberated. (COMIC: Assimilation²)

Following the Cyber-Wars, three centuries after their defeat in the Vogan War, a ship of CyberNomads caught up to Voga, now in orbit around Jupiter. Their attempt to destroy it was defeated due to the involvement of the Fourth Doctor, Sarah Jane Smith, and Harry Sullivan. They and their ship were destroyed by the Vogan missile Skystriker. (TV: Revenge of the Cybermen) Records of this defeat were consulted by the Cybermen in 2526. (TV: Earthshock)

Hegelia hypothesised that another group of CyberNomads might have reopened the Telosian tombs and helped to forge the new race of Cybermen, the Neomorphs, which proliferated during the 26th century. (PROSE: Killing Ground)

During the "Late Expansion Era", the CyberNomads sought to invade Poseidon, intending to use it as a beachhead for a later invasion of Ultima Tarsus, only to fall victim to the Void energy sent out by a rogue Type 1 TARDIS. Being driven to proceed in invading the station, the CyberNomads were destroyed when the Tenth Doctor activated Poseidon's self-destruct. (COMIC: The Lost Dimension)

Alternate timeline
In an alternate timeline where the Cybermen at the end of the universe allied with Rassilon to take over history, a time distortion interrupted a confrontation between the Third Doctor and, resulting in the latter being converted into what resembled a CyberNomad. (COMIC: Prologue: The Third Doctor)

Elsewhere, a Nomad Cyber-Leader commanded CyberIsomorphs on Skaro, where the Cybermen had erased the Daleks from history. When the Fifth Doctor and Peri Brown arrived on the planet, the Cyber-Leader identified the Doctor and ordered their subordinates to kill him. Ultimately, this timeline was negated when the Twelfth Doctor and Rassilon regenerated the universe. (COMIC: Prologue: The Fifth Doctor, Supremacy of the Cybermen)

Other references
The Nomad Cyber-Leader that led the Cybermen's attack on Nerva Beacon was among the foes whom the Fourth Doctor saw call out to him in his mind shortly before his fall from the Pharos Project radio telescope, which resulted in his regeneration to his next incarnation. (TV: Logopolis)

Behind the scenes
The term "CyberNomad", used in PROSE: Killing Ground has its origins in the non-narrative encyclopaedic book, Doctor Who: Cybermen, by David Banks. Among the terms and theories invented by Banks to explain the variations in the Cyberman, "CyberNomad" referred to the Cybermen originally seen in TV: Revenge of the Cybermen.

The CyberNomads were groups of Cybermen that split off from the CyberFaction in the Second Cyberman Divergence some time after the destruction of Mondas. While the CyberFaction stayed within the Sol system, the CyberNomads ventured out into the Mutter's Spiral. (REF: Doctor Who: Cybermen)

Sometime before the 26th century, a group of CyberNomads discovered frozen CyberTelosians, resulting in the CyberNeomorphs. (REF: Doctor Who: Cybermen)
