The Vault Daleks
Place of origin:
The Stolen Earth/ Journeys End
The Vault Daleks (or Crucible Daleks) were a subset of Daleks unique to the New Dalek Empire possessing a specialised manipulator arm. They were charged with guarding their creator Davros in the Vault, a special chamber within their giant space station the Crucible.
Like every individual Dalek of the New Dalek Empire, the Vault Daleks were created from a single cell of Davros’ body. However, they differed from the other New Daleks on account of their special type of manipulator arm: a claw possessing eight pincers, to access special hardware within the Vault. They were tasked by the New Empire’s leader, the Supreme Dalek, to keep watch over their creator Davros inside the Vault. (The Stolen Earth/Journey’s End)
The Vault Daleks were destroyed when the Meta-Crisis Doctor caused a backfire which destroyed them. (Journey’s End)
Behind the scenes
Vault Daleks were not named during The Stolen Earth/Journey’s End, but are referred to as such on the official BBC website.
They have also become known as “Crucible Daleks”, primarily due to the toy manufacturer Character Options naming the variant in this manner as part of its range of Doctor Who 5 inch action figures.
