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.
