Two Skalengecks named Clint Vickers and Joshua Hall rob a local spice shop, and kill Freddy Calvert the owner. Nick gets a call from Rosalee, who says that the two Skalengecks returned, but she stabbed one. Nick and Hank go to their apartment, and the two Skalengecks fire their guns at them, but get away, due to Hank's hallucination. Later, Rosalee gets two tickets to a Wesen crack house from Cecil. While searching, Nick finds them, and he tries to shoot Nick, but Nick knocks him out, but the gun shots scare the other Wesen in the crack house. When the other Skalengeck holds Monroe at gunpoint, Rosalee uses a brick and knocks him down, allowing Nick to arrest him.
Two Skalengecks are hired by Arbok, a Königschlange, who assigned them for the job of killing Monroe, as a way to send a message to those Wesen that are friends of a Grimm. But one of them dies after an attempt to rape Angelina Lasser, who kills him in self-defense, so Arbok decides to hire her to do the job of the dead. The other one, Terrence, is killed by Monroe after he shoots Angelina.
A Skalengeck named Gus Campbell along with Cole Pritchard and Krystal Fletcher, a Blutbaden couple, went on a robbing spree fully woged breaking the Gesetzbuch Ehrenkodex. When he wanted to leave the group after Cole killed two people, Cole attacked him. Krystal stopped Cole, but then she woged and bit out Gus' throat.
As Trubel walks away from a store after setting of the fire alarm and stealing a pair of boots, a female gangbanger Skalengeck follows her. She taunts Trubel as she tells Trubel to give her the boots she stole. Trubel refuses and pulls out her knife, while the Skalengeck woges and attacks. A jogger passes by as they are fighting and he calls 911. After a back and forth fight, Trubel eventually gets the upper hand and slashes and stabs the Skalengeck with her knife, eventually leading to the Skalengeck's death soon after the paramedics arrive.
When they woge, they gain pale yellow scaled skin over their face, have forked tongues and sharp pointy teeth. They also have three gills on both sides of their neck. The exact purpose of these gills are unknown, but Clint Vickers and Joshua Hall were seen venting Jay fumes that they inhaled out of them, so it is clear that the gills are part of the Skalengeck respiratory system.
They are stronger than humans, as one was able to fight with Trubel, a Grimm, on equal footing for a while, ("Nobody Knows the Trubel I've Seen") and Nick wrestled one evenly, ("Island of Dreams") although they are still somewhat weaker than Grimms. They are also very fast.
Interestingly, they obviously don't have the regenerative power that many actual lizards have, as seen in "Island of Dreams", where one sustained an injury on his leg and had to manually sew it closed.
As a defense mechanism, the Skalengeck secretes a foul odor from its skin. This odor is pungent, but harmless. ("The Killing Time")
Skalengecks usually intimidate their prey by greeting them with a hostile grin and their tongues hanging out. They are a species not renowned for their intelligence, or width of knowledge. They are often aggressive, irrational, and violent. This can lead them to try and take on far superior opponents. The majority of them are criminals ranging from addicts and sexual abusers, to robbers and murderers. However, there are more intelligent and more competent Skalengecks such as Gus Campbell.
Its been implied in their main appearances that they have a high tolerance for flesh wounds, and enjoy inhaling things. ("Leave It to Beavers")
- Skalengecks are not affected by pepper spray. Monroe assumes that they actually like it. ("Leave It to Beavers").
