|Seen In||"Over My Dead Body"|
They are an extremely unpleasant and dangerous Wesen species, Monroe mentioned he does not want anything to do with them. They're so dangerous that even Blutbaden fear them, and their name is enough to invoke fear in other Wesen. They also seem somewhat sadistic, and enjoy intimidating others.
They are highly suspicious creatures and are very rarely deceived.
Upon Woge their skin turns scaly, a distinctive hood forms, and they gain a serpent like tongue and fangs.
They have incredible senses, particularly smell and touch, and are sensitive to temperature and can detect weak vibrations. Their acute senses are not foolproof, and anyone who is under the effect of the Dead Faint potion can trick a Königschlange into thinking they are dead. Because of their unique skill, they are generally sought after by those wishing to unmistakably confirm an individual's death, as well as being a living lie detector of sorts. In short, they typically find employment through exceptionally shady avenues.
They also have sharp fangs that release a deadly toxin into whatever they puncture. Königschlange are extremely fast and have incredible reflexes that far exceed that of a Grimm. When Königschlange combine these traits with their impressive physical strength it enables them to go toe-to-toe with Grimms.
- Königschlange is spelled and pronounced almost (but not quite) the same as Königsschlange ("king's snake"), which is a German word that refers to the boa constrictor.
- If Arbok's name is read backward it is the German word for cobra (Kobra).
