Weapons-grade Cyberman

What the Twelfth Doctor identified as a "weapons-grade version" of Cyberman. (TV: The Doctor Falls)

Characteristics
The "weapons-grade" Cyber-body was sleeker and far less bulky than previous models. They had chest units which gave a blue glow whilst no circuitry was visible outside the suit and they developed a plethora of new features: these Cybermen could move at blurring speed, to the point where everything around them would seem frozen. They were capable of rotating their heads 180 degrees, as well as being able to detach body parts such as their Cyber-hands or their Cyber-head. Their armour was thick enough to deflect lasers, though an anti-cyber gun could completely disintegrate them. (TV: Nightmare in Silver, The Time of the Doctor)

Origins
"Weapons-grade" Cybermen were upgraded from the Cyber Legions, which were speculated by one source to be the result of cross-pollination between two Cyber-races: the Cybermen of Mondas and their descendants, (PROSE: The Whoniverse) who had previously fought numerous Cyber-Wars against humanity, (TV: Revenge of the Cybermen et al.) and the Cybermen of Cybus Industries, (PROSE: The Whoniverse) the latter of whom, having failed to conquer their universe's Earth, (TV: Rise of the Cybermen, The Age of Steel) had crossed into N-Space and attempted to conquer its Earth instead, (TV: Army of Ghosts, Doomsday) only to be reduced to scattered remnants across N-Space thanks to the Tenth Doctor, (TV: Cyberwoman, PROSE: Made of Steel, COMIC: The Power of the Cybermen)

Aboard a Mondasian colony ship, one of numerous places where the Cybermen began as a result of parallel universe, "weapons-grade" Cyberman advanced from Cybermen identical to those of the Cyber Legions, with both following from the original CyberMondasians. The first of these "weapons-grade" Cybermen to attack was killed through a combination of the Mondasian-converted Bill Potts' cyber-weapon, 's laser screwdriver, 's sonic umbrella and the Twelfth Doctor's sonic screwdriver. In the Battle of Floor 0507, numerous "weapons-grade" Cybermen, along with "Cyber Legion" Cybermen and CyberMondasians, moved to upgrade the remaining Mondasians only to be destroyed by the Doctor.

In 2010s, a weapons-grade Cyberman was a resident of the hidden trap street in London which housed lost aliens on Earth under the protection of Mayor Me. As with the rest of the inhabitants, it appeared cloaked in human form through use of the lurkworms. It was observed by the Twelfth Doctor and Clara Oswald as it had maintenance performed on it by an Ood. (TV: Face the Raven)

Handles and Trenzalore
A group of twelve "weapons-grade" Cybermen, formerly of the Cyber-Legions, were acquired and modified by Dorium Maldovar to function as a patrol of guards for the Maldovarium. When Kiz the Head-Taker, Vertebrae and Agrakos attempted a theft of the Maldovarium, all of Dorium's Cybermen were beheaded by Kiz, with one Cyber-head being used to keep a door wedged open for when the three criminals escaped, with an Auton copy of Dorium naming this Cyber-head "Handles". Later, when Kiz chose to escape alone, he found that somebody had moved Handles from the door, cleaned it, and placed the Cyberman head in the centre of the door's service duct, locking him and the others inside the Maldovarium. (PROSE: The Heist)

Stripped of all organics, Handles was eventually acquired from the Maldovar market by the Eleventh Doctor. Handles went on to assist the Doctor when a message began repeating throughout the universe from the planet Trenzalore. Among the spacecraft that converged on Trenzalore were Cyber-ships manned by weapons-grade Cybermen. Handles teleported the Doctor aboard several of the ships only to teleport him back when the crews inevitably opened fire on him. One one occasion Handles was brought aboard one of the ships as a symbol of comradeship only for the Doctor to discover it was a cyber-ship, the Cybermen opening fire with the Doctor using Handles' immunity to cyber-weapons as a shield. Handles' analysis of the message led to him identifying the planet as Gallifrey, finding the message to be of Gallifreyan origin. Investigating the message in person, the Doctor affixed a Seal of the High Council to Handles allowing him to fully decode the message which Handles broadcast to the entirety of the orbiting fleet: "Doctor Who?".

Handles remained with the Doctor as he stayed to defend the planet from the numerous species that sought to prevent the Time Lords from returning to the universe, including the Cybermen. On one occasion, the Cybermen dispatched a Wooden Cyberman to bypass the Papal Mainframe's Trenzalore force field, only for the Doctor to destroy it using its own weapon, a wrist-mounted flamethrower. Ultimately, after 300 years in the town of Trenzalore, Handles broke down, much to the Doctor's dismay. Shortly after, the Siege of Trenzalore escalated when the force field was broken by the Daleks. Over the following centuries, Cybermen were among the forces that landed on the planet and were fought by the Doctor and his allies, the Silents. By the end of the siege, all the invaders had "retreated or burned". (TV: The Time of the Doctor)

The Cyber-Wars
In the 250th Millennium, a series of Cyber-Wars (PROSE: The Secret Lives of Monsters) were waged by the Cybermen of the Cyber Legions including "weapons-grade" models, and the Cybus Cybermen. The conflict was devastating for humanity, as the Cybermen were able to quickly upgrade themselves to respond to their foes' weaponry and then move in to convert their enemies. The conflicts finally ended when the Tiberian spiral galaxy was blown up, destroying apparently all of the Cybermen. (TV: Nightmare in Silver)

Sometime after the destruction of the Tiberian spiral galaxy, the hand and arm of a "weapons-grade" Cyberman came to be regarded as a legendary "gauntlet" that granted immortality and could radically improve any form of technology. The gauntlet was traded across numerous planets and was pursued by Seeker Sylen of Catrigan Nova over several years, until Sylen acquired the gauntlet and presented it to Lydia, queen of Catrigan Nova, as a gift. Lydia, unaware of the gauntlet's true nature, used it over several days to improve the technology of Nova Palace, and to partially cyber-convert her soldiers. Lydia also accidentally used the gauntlet on her daughter, but her partial conversion was reversed by the Twelfth Doctor, who had been pursuing the gauntlet for a while. As the guards gradually became complete Cybermen, they began "conscripting" people to Nova Palace for conversion, but were eventually destroyed by the Doctor who, using Lydia as bait, lured the Cybermen to the planet's liquid gold whirlpools, dissolving them, along with Lydia's gauntlet.
