Hoix were a race of omnivorous creatures.
Files in 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. (TV: Exit Wounds) The Doctor was aware of this and also of what effects hot chemicals had on the Hoix. (TV: Love & Monsters)

In the spring of 2007, Elton Pope opened a door inside a warehouse in Woolwich, startling a Hoix who was right behind it. The Hoix was about to attack him, but luckily for Elton, the Doctor was able to distract the Hoix by teasing it with a piece of raw meat while Rose Tyler threw a bucket of liquid on the Hoix. Unfortunately, this was the wrong bucket, which just made the Hoix angry. Rose and the Doctor were chased by the Hoix until Rose was able to find the correct bucket. (TV: Love & Monsters)
The Vandrogonite Visualiser that was dug up in Rhiwbina in October 2008 had records of the Hoix. When Gareth Portland created MonstaQuest, he used the Hoix as several of the characters, naming them "Maymer" and "Bludgeon Beast". One was accidentally summoned into the Achenbrite headquarters, along with two Chantri Golems, where it killed the members before they could respond. It was later killed by Jennifer Portland, who flooded the building with kolokine-7. (PROSE: Pack Animals)
In 2009, a Hoix came through the Cardiff rift into St. Helen's Hospital, Cardiff. A doctor trapped it in a boiler room but ultimately Owen Harper had to lure it out with cigarettes and tranquillise it. (TV: Exit Wounds)
