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)

Their energy bolts 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 energy 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)
