Vinvocci

The Vinvocci were a species of green-skinned, spiky humanoids, whose sentience and intelligence were similar to those of humans.

Biology
The Vinvocci were green, spiky humanoids. They resembled the Zocci, but were taller and green. (DW: The End of Time)

Technology


Rossiter and Addams used shimmers to appear as humans. These devices, disguised as a wristwatch, allowed Rossiter and Addams to work for Joshua Naismith undetected. However the device was uncomfortable to use.

Rossiter and Addams also had a salvage spaceship. It had a teleport system connected to the wristwatches and several sets of automated laser weapons for destroying asteroids. (DW: The End of Time)

Culture
The Vinvocci found the term cactus being used to to describe them to be offensive. (DW: The End of Time)

History
In December 2009, a salvage team, consisting of Rossiter and Addams, arrived on Earth to find the Immortality Gate. The Gate had been reactivated by humans, and had sent out a signal which attracted the pair. They infiltrated the company of Joshua Naismith, under the guise of two human scientists. They were trying to repair the Immortality Gate, but the Master stopped their plans by using it to transform every human on Earth into duplicates of himself.

The Vinvocci, unaffected due to their alien nature, helped the Tenth Doctor and Wilfred Mott escape the Master, bringing them to their ship. They later helped the Doctor return to the Naismith mansion, dropping off Wilfred Mott shortly after. They then departed, unwilling to involve themselves any further in the conflict.
