Hoolox

The Hoolox were an ape-like warrior race. They resembled upright simian gorillas that were wore a type of chest body armour.

History
They were one of the races along with the Nin, and the similarly warlike crocodile-like Sraal, were duped into beleiving that they have rightfully bought the Earth. (COMIC: The Day the Earth Was Sold) However, that was a mistake due to the human boy, Robbie, who was then playing with it, not knowing or intending what would happen. (COMIC: The King of Earth) Not convinced with the doctor's explaination, the Hoolox launched a missile attack that was powerful enough to burn the planet. (COMIC: The Day the Earth Was Sold)

The Tenth Doctor was able to enlist the help of the formally duped but peaceful Nin to prevent the attack. In response, the Hoolox joined forces with the Sraal. Despite that, the advanced technology of the Nin was no match to their combined forces. The Doctor was able to contact the owner of the device, the real estate agent Fliant Wormbleeder, who then settles the dispute by offering each race a proper home. (COMIC: The King of Earth)
