Zentra mothership
From Tardis Wiki, the free Doctor Who reference
The Zentra mothership was a rusty spacecraft barely kept spaceworthy by the Zentrabots. It was captained by Karvox.
History
Using the Zentrabots as a Christmas "toy craze", the Zentra took children from Earth to the ship, where they demanded to at least one of its governments that it would hand its weapons to the Zentra or they would die.
The Eleventh Doctor tracked the Zentrabots' signal to the ship, taking Danny along with him. The Doctor reprogrammed the Zentrabots to attack the Zentra guards and released the children from their holding cell. (COMIC: The Zentrabot Invasion)
