The Zoats are a race of centaur-like lizard creatures that appear in Games Workshops Warhammer Fantasy. Zoats were also present in the earliest editions of Warhammer's companion Warhammer 40,000 science-fiction setting, but have since been written out of the background.
Zoats are large, strange, centaurlike creatures, representing many fantasy archetypes related to nature and wilderness (and, in their Warhammer 40,000 incarnation, organic technology). In Warhammer, Zoats are powerful forest magicians, but also secretive isolationists, living only in the deepest woodlands and avoiding contact with outsiders if at all possible. By contrast, the Zoats of Warhammer 40,000 were a much more cosmopolitan species, often found fighting as mercenaries. They communicated telepathically, and had other prodigious abilities to assimilate into other cultures. Zoats in Warhammer Fantasy fight with heavy stone maces called sky-staves, while those in WH40K were equipped with futuristic organic weapons.
