The Houndeye is a tripedal creature native to the alternate dimension known as Xen.


Possessing only three legs and a thorax, the Houndeye is a faint yellow-green in color, with electric blue tiger-like stripes adorning its spine. In place of a head there is a large, black, insect-like compound eye protected by eyelids. Houndeyes apparently communicate through a series of high-pitched sounds somewhat similar to the barking of dogs.

The Houndeye is an excellent example of a social animal in terms of pack hunting. While a shy and timid creature by itself, groups of three or more display resonant behavior, emitting destructive harmonic sonic attacks in shock waves, capable of injuring those they attack or destroying nearby objects such as wooden crates or windows. The shock waves are always visible, appearing as violet or white circles around the creature. The eyelids are seen moving only when they are excited.

Although they are not seen displaying this trait often, Houndeyes appear to be carnivorous creatures, as one is seen eating a dead security guard. The Houndeye's mouth is located on the underside of its belly, close to the eye, filled with what appears to be fang-like incisors.
