Lebensauger (Germ. Leben "life" + Sauger "sucker") are hideous lamprey-like Wesen that have porous skin and large, funnel-like mouths with sharp teeth. Due to their hideous appearance, they often experience self-loathing and even identity crisis. They are generally considered to be amongst the most repulsive of Wesen and are subsequently known to be prone to substance abuse. Lebensauger are exceptionally good at keeping their true nature secretive and rarely Woge in front of other Wesen.
Grimm creatures + Wesen A Hexenbiest (HEK-sən-beest; pl: -biester Germ. Hexe “witch” + Biest “beast”) is a witch-like Wesen that resembles a zombie, with visibly rotting or disfigured flesh. Rosalee indicated that the term Hexenbiest is reserved for the female, while a male (such as Renard) would instead be called a Zauberbiest (TSOW-bər-beest; Germ. Zauber “magic” or Zauberer “wizard” + Biest “beast”). (“Mr. Sandman”)
