Ziegevolk, Musai, and Cracher-Mortel all have abilities that allow them to influence or have complete control over people. Ziegevolk use their pheromones to control and manipulate whoever they want, usually women. ("Lonelyhearts") ("One Angry Fuchsbau") The lips of Musais secrete a psychotropic substance, making their kiss known to be very euphoric and addictive. After they kiss someone, they are able to easily manipulate their victims, who will do whatever they have to in order to prove their love for the Musai, even kill someone or die themselves. ("Kiss of the Muse") Cracher-Mortel have the ability to create an army of zombie-like victims by spitting tetradotoxin on to the face of a victim, which seeps into the skin of the victim or is inhaled by the victim and shuts down the neurosignals of nerves and heart cells, causing suspended animation. Atropine and scopolamine toxins reanimate the victim in a zombified state. In this state, the victim is in a trance and will perform whatever task is asked of them by the Cracher-Mortel. ("The Waking Dead") ("Goodnight, Sweet Grimm") ("The Ungrateful Dead")
Despite being parahuman themselves, many Wesen eat humans (ex: Blutbaden, Schakals, Wendigo, Coyotls, and Mauvais Dentes) or other Wesen (ex: Blutbaden eat Bauerschwein and Seelengut, while Lausenschlange eat Mauzhertz).
Some Wesen, like Raub-Kondors, hunt other Wesen, such as Glühenvolk, for their skins. They use a potion called Sauver Sa Peau to keep them woged after death for up to 8 hours so they can skin them. ("Endangered") Vulpesmyrca use a similar method to keep the foot of a Willahara woged so they can sell it for the illegal practice of Spedigberendess. ("Bad Luck") Vibora Dorada use their sharp fangs to inject a neurotoxin into their victims. It paralyzes them, and if the victim is woged when they are bit, the neurotoxin will keep them in that state
