|Mentioned||"The Hour of Death"|
The Endezeichen Grimm (Germ. endezeichen "end sign") were the worst of the worst, a sect of merciless, intolerant Grimms devoid of any compassion whatsoever. It is said that they would roam the countryside mercilessly killing Wesen men, women, children and even pets. It did not matter to Endezeichen Grimms if a Wesen was good or evil: in the eyes of Endezeichen Grimms all Wesen are inhuman abominations to be eradicated. In "The Hour of Death" Monroe told Nick and Hank that he heard fairy tales of this type of Grimm while growing up, but was told that, luckily, these Grimms no longer exist.
Endezeichen Grimms were known to be inhumanely brutal, torturing captive Wesen and cutting fingers, toes, arms, legs, even genitals as grisly trophies. Their brutal tactics and indiscriminate killing of Wesen set Endezeichen Grimms apart from regular Grimms, who usually only kill evil Wesen, and even then resort to the quickest and cleanest method. To this day Wesen parents make sure to tell their children about Endezeichen Grimms via Albtraume fur Wesen Kinder, the Wesen equivalent of fairy tales.
The Sterbestunde G (Germ. sterbestunde "hour of death") was their symbol, which was stylized to look like a human skull. Endezeichen Grimms branded it into every Wesen they killed and drew it with the blood of their victims on every house of every village that had Wesen in it. It was branded by having the symbol shaped with metal and highly heated by fire then stamped on the victim.
Aside from their brutal tactics and the Sterbestund G Endezeichen Grimms had additional trademarks. Endezeichen Grimms wore black hooded cloaks that went down to tops of their feet; concealing their entire body. In addition to their cloaks Endezeichen Grimms wore full face masks that had a vague skull-like appearance. The Endezeichen Grimms likely wore these garments to conceal their true identity from humans, Wesen, and regular Grimms. This would make it much harder for anyone to bring the Endezeichen Grimms to justice thus allowing them to kill Wesen with near impunity.
The Endezeichen Grimms are generally thought to have died out by most Wesen, but their memory is still powerful. As a result of the Endezeichen Grimms, most Wesen fear all Grimms and will do everything they can to flee from them, due to the fact that for centuries, they had no way of knowing whether or not the Grimm is an Endezeichen Grimm.
Endezeichen Grimms have similarities to the Reapers. Like Endezeichen Grimms, Reapers wear long dark clothing and draw their trademark symbol with the blood of their victims.
During one case, Nick Burkhardt believed that he was dealing with an Endezeichen Grimm who tortured a Wesen responsible for an abduction to force a confession out of him, the 'Grimm' later abducting Bud with the intention of torturing him, but the investigation revealed that the person responsible was actually Ryan Smulson, an intern at the department who turned out to be a Lebensauger attempting to act like a Grimm due to a psychotic breakdown.
