The Wolvarks are a species in Oddworld that are ruthless towards any of the other species, especially the Grubbs. There only seems to be male Wolvarks in the game, that or it's only the males who work for Mr. Sekto and cause trouble. Unlike the Clakkerz and Outlaws, who have Western accents, Wolvarks appear to have Southern accents. These creatures almost look reptilian, with a tail. The Wolvarks have green or pale beige skin tone with beady eyes and ears protruding from the sides of their head. They are skinny and ugly, as their underbite contributes to their disgusting tail. They resemble toads as their scales are grubby and have warts on some parts of their face.
There only seems to be male Wolvarks in the game, that or it's only the males who work for Mr. Sekto and cause trouble. They are sadistic rednecks who are ill-minded and would die out of their stupidity for their duty. Different from the Outlaws, these soldiers are trained under the leadership of Mr. Sekto and are vicious to the point of killing anything that stands in their way of Sekto's call of duty. They were employed by Sekto to protect his own industry from anyone who opposed or seemed to be a threat to him and his businesses: Sekto Spring Dam and Sekto Spring Bottled Water Company. They are known for being the underhanded mercenaries of the evil captains of industry at this time.
Wolvarks are cruel and unintelligent beings that have a lust for death. They are known to steal the Grubb's land by the order of their boss; this leads to further bombings of the Grubb's sacred villages and an ordered ban on fishing. Their cruel personality plays out through their means of enforcing their boss's word by impaling, hanging, and crucifying the Grubb's who were caught in the act of fishing. Their ill-minded nature is disturbing as they will do anything to get the job done, leaving a slaughter of the Grubb's people in a ruthless fashion. They are increasingly dim and lazy, usually spending their time watching idiotic television shows or practising the art of taxidermy. They are corrupt and sadistic, just like their leader. Also, Wolvarks love enjoying the smell of roadkill. They will die for their paycheck, which gives them a meaning in life within all of Western Mudos.
