A Reality bomb is on the Dalek's mothership. The Daleks want to use it to destroy the universe. As it is too dangerous inside the mothership, the Doctor needs to rebuild, rewire and hack a Dalek. For this the Doctor has to built a Dalek shell, by using the parts he finds. He rewires the Dalek to the micro:bit and overrides its systems. Then he programs the micro:bit to control the Dalek. After this he saves the universe by ejecting the reality bomb out of the airlock.
- The Dalek's casing is divided into three sections, the top dome and grating section, the middle weapons platform and the bottom base unit. For customisation, a choice of six colours can be applied to the sections.

- Blue Dalek: Analogous to the Strategist Dalek.
- Yellow Dalek: Analogous to the Eternal Dalek.
- Orange Dalek: Analogous to the Scientist Dalek.
