The Hoix were a race of omnivorous humanoids.
Biology
The Hoix, as mentioned, were a humanoid race. They were slightly shorter than the average Human and had brown skin, sharp teeth and exposed gums.
Files by the Torchwood Institute suggested that the Hoix lived to eat, and one Hoix specimen apparently liked to eat everything. Owen Harper noted how unintelligent they appeared to be. (TW: Exit Wounds) The Doctor was aware of this and also of what effects various chemicals had on the Hoix. (DW: Love & Monsters)
History
Torchwood Institute had encounter the Hoix before. In one instance, one was found in Barry, where it had broken into a restaurant. (TW: Exit Wounds)
In the summer of 2007, one Hoix was encountered by Elton Pope. Pope, in search of the Doctor, had managed to locate the Doctor's TARDIS. While following voices into abandoned warehouse, Elton startled the Hoix who attempted to attack him. The Doctor was able to distract the fierce-seeming Hoix with a piece of raw meat and Rose Tyler threw a bucket of liquid at the Hoix. Unfortunately, this was the wrong bucket, which just made the Hoix angry. Rose and the Doctor were then chased by the Hoix until Rose was able to find the correct bucket. (DW: Love & Monsters)
- Nothing is known about the Hoix or why the Doctor was chasing him/her or how (or if) they eventually defeated him/her.
In 2009, a Hoix (whether it was the same one or different) came through the Cardiff rift into St. Helen's Hospital, Cardiff. A doctor trapped it but ultimately Owen Harper had to lure it out and tranquillise it. (TW: Exit Wounds)
- It is unknown what happened to the Hoix after this, although most aliens found by Torchwood 3 ended up in the Hub's vaults.
Notes
The Hoix look a lot like the Bailiffs of the Vandosians and the Vandosians themselves. The similarities continue with the use of the bucket and its contents to combat the creatures as seen in Mr. Nobody.
Behind the Scenes
There has been some confusion over whether 'Hoix' was the name of the individual creature appearing in Love & Monsters, or of its species. Doctor Who Top Trumps suggested it was the species' name, although this information is non-canonical. In Exit Wounds, Owen Harper talks about it in a manner that lays the matter to rest - Hoix is the name of the species.
