Suction cup
The suction cup, also known as the suction probe, (PROSE: Dalek Combat Training Manual [+]Loading...["Dalek Combat Training Manual (reference book)"]) suction pad, sucker pad, (PROSE: Doctor Who in an Exciting Adventure with the Daleks [+]Loading...["Doctor Who in an Exciting Adventure with the Daleks (novelisation)"]) sucker cup, (PROSE: The Dalek Generation [+]Loading...["The Dalek Generation (novel)"]) sucker attachment, (PROSE: Dalek Survival Guide [+]Loading...["Dalek Survival Guide (novel)"]) or simply sucker, was the eponymous tip at the end of the suction arm, the standard Dalek manipulator arm. The Tenth Doctor observed that they were the Daleks' equivalent of a hand. (PROSE: Prisoner of the Daleks [+]Loading...["Prisoner of the Daleks (novel)"])
While a minority of Daleks, such as Elite Guard Daleks of the Time War (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) and Vault Daleks of the New Dalek Empire, naturally wielded alternative manipulator arms, (TV: The Stolen Earth [+]Loading...["The Stolen Earth (TV story)"]) other Daleks could temporarily exchange their suction cups for other appendages which served their needs, such as when Dalek Jast used a syringe to administer a solution for Dalek Sec's Human-Dalek form.

Development
In one account of the genesis of the Daleks, Davros installed a multi-dextrous claw "capable of annihilating a million Thals" on his first Dalek. However, the claw was broken off when the Doctor's TARDIS collided with the Dalek. As compensation, the Fourteenth Doctor gave a plunger from the TARDIS to Castavillian to replace the claw. Discovering the modification to the casing he created, Davros decided that he liked it, (TV: Destination: Skaro [+]Loading...["Destination: Skaro (TV story)"]) leading to what would become known as the suction cup becoming the norm.

Function
To accomodate the suction cup, Dalek technology often had circular controls which the Daleks could arm or disarm by rotating. The black tip at the end, which gave the arm its "plunger" shape, could alter its form to better interact with specific objects, for example, finding the combination of electronically-locked doors.

Even if the Dalek died, its arm could still operate machinery for a live person. (TV: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (TV story)"]) The arm also had a telescopic feature to extend its length. (TV: The Dalek Invasion of Earth [+]Loading...["The Dalek Invasion of Earth (TV story)"], Dalek [+]Loading...["Dalek (TV story)"])
It could also serve as a weapon; with the tip placed over the nose and mouth, the arm could generate suction to suffocate and kill a human and enough traction to crush a human skull or rip through sheet metal. (TV: Dalek [+]Loading...["Dalek (TV story)"], TV: Doomsday [+]Loading...["Doomsday (TV story)"], PROSE: I Am a Dalek [+]Loading...["I Am a Dalek (novel)"]) The Tenth Doctor claimed to have seen Daleks crush bricks with ease. (PROSE: Prisoner of the Daleks [+]Loading...["Prisoner of the Daleks (novel)"]) As demonstrated by the Bronze Daleks, the suction cups could be used to project fire, functioning as flamethrowers alternative to the pyro-flame or flame gun. (COMIC: The Dalek Project [+]Loading...["The Dalek Project (comic story)"])
At least in the case of the Cult of Skaro, the arm could also scan brainwaves for information or act as a quick intelligence scan. (TV: Doomsday [+]Loading...["Doomsday (TV story)"], Daleks in Manhattan [+]Loading...["Daleks in Manhattan (TV story)"]) However, if a large amount of information needed to be analysed, it could be drained out by force by encasing a subject's head inside their "plunger" tips, which would stretch the victim's head and brain to wring out their knowledge through information probes. The probes were strong enough to have a deadly effect on humans, draining them so fiercely that their bodies shrivelled up and became burned out husks.

Imperial Daleks had a more conical variant, with a slotted rim specifically designed to operate controls. (TV: Remembrance of the Daleks [+]Loading...["Remembrance of the Daleks (TV story)"])
Behind the scenes
- The suction arm was notably the very first part of a Dalek to appear on-screen, as seen attached to the Dalek which confronts Barbara Wright within the Dalek City at the very end of their first episode, "The Dead Planet". The Daleks would only be revealed in full in their second episode, "The Survivors".
- In the online video game, The Last Dalek, the player can use the "Metaltron's" extending suction arm as a close-quarter weapon. The suction cup's ability to bypass locks is utilised via a Bio Processor.
- The Power of the Doctor was the first and only appearance of Daleks with standard suction cups in the televised Thirteenth Doctor era following the Reconnaissance Dalek, Defence Drone, Death Squad Daleks and Dalek Executioners, all of which wielded a form of claw manipulator.
