Wrist-gun

Wrist-guns were the Eighth Doctor's term for the Autons' signature energy weapons, (AUDIO: Brave New Town) concealed within their hands and only revealed when their fingers dropped away on a hinge. (TV: Spearhead from Space, Terror of the Autons, Rose, The Pandorica Opens, The Big Bang)

Characteristics
They fired concentrated energy bolts (PROSE: Strangers in the Outland) which were a refined form of telekinesis, ripping matter apart at the sub-atomic level, (PROSE: Synthespians) although Nestene creatures were able to reflect these bolts should an Auton fire at them. (PROSE: Autonomy) They could also spray gas. (COMIC: Plastic Millenium)

Although not always utilised, wrist-guns were capable of "total destruction" in which targets were completely vaporised, including humans that would disappear in an implosion of orange smoke (TV: Spearhead from Space) and even a large truck which disintegrated with a yellow haze. (HOMEVID: Auton 2: Sentinel)

When used on the eyestalk of the Stone Dalek, a wrist-gun was able to disable it. However, the restoration field from the Pandorica quickly restored the damage done to the Dalek. Further shots to the weakened Dalek's shell again disabled it briefly, but the Dalek quickly recovered from the shots. (TV: The Big Bang)

History
In 102, Autons disguised as Roman soldiers of the Alliance at Stonehenge presented their wrist-guns when they revealed themselves. Rory Williams, who had been transformed into an Auton following his death and temporal erasure, involuntarily shot his fiance, Amy Pond. (TV: The Pandorica Opens) However, Amy was revived by being placed within the Pandorica.

In 1996 of the post-total event collapse alternate timeline, Rory acted as security guard of the National Museum which contained the Pandorica. Using his wrist-gun, Rory temporarily disabled a Stone Dalek to protect the Eleventh Doctor and his companions. However, the weakened Dalek was able to recover due to the restoration field of the Pandorica. (TV: The Big Bang)

During the Nestene Consciousness invasion of Earth in the late 20th century, Autons acting on the orders of Channing used their wrist-guns both to kill and dispose of the corpses of John Ransome and George Hibbert. Across the United Kingdom, Auton mannequins attacked humans before stopping as the Nestene was defeated by the Third Doctor and UNIT. (TV: Spearhead from Space)

During the Nestenes' invasion of Earth on 5 March 2005, Auton shop window dummies used their wrist-guns to attack humans as they rampaged throughout London before the Nestene was defeated by the Ninth Doctor and Rose Tyler. One such victim was Clive Finch. (TV: Rose, Love & Monsters, PROSE: Rose)
