Grimm

"A Grimm is someone who can see into the heart of darkness. Someone who sees things other people don't understand."

- Monroe to Juliette

A Grimm (Latin: dēcapitāre) is a special person who possesses incredible powers such as being able to see the true form of Wesen, even when the Wesen don't want them to. For centuries Grimms have placed it upon themselves to police and hunt the Wesen population and to protect normal humans from the unknown threat around them.

History
During the Fourth Crusade, seven knights in service to the Seven Houses participated in the sack of Constantinople. The knights brought back a treasure from Constantinople so powerful, that they feared it coming into the possession of their masters. They hid the treasure and created a map in seven parts. Despite this, there have been Grimms for much longer than this, the earliest known ones were alive in the first century AD  .

The knights are the earliest known individuals who possessed these traits, and the ancestors of what would come to be commonly known by the mid-1810s as Grimms (named after the The Brothers Grimm, who, ironically, did not inherit these traits from their ancestors and instead collected and recorded what they believed to be the mythologies of the world). These knights were needed to keep the Wesen in line that made up the brunt of the Royals' Army.

Over the next several centuries, the Grimms served as the (usually) freelance police of the Wesen world, dispatching those who could not live in peace with humans (by contrast, the Verrat enforced the internal rules of Wesen society). As a general rule, it was the responsibility of the Grimms to hunt down "the bad ones", those aggressive and malicious Wesen who preyed on humans or other Wesen. The majority of Grimms were only exposed to the Wesen community through these malcontents, leading some of them, namely the Endezeichen Grimms, to consider all Wesen abominations that needed to be exterminated.

It appears that Grimms were involved in the Council of Walenstadt in 1521, where the Gesetzbuch Ehrenkodex, or the rules set to prevent Wesen revealing their true form was set up, as Monroe describes the event as "a Grimm event too" and there were details about it in one of Nick's Grimm Diaries.

In 1682 Grimms signed the Charter of Wittenberg, an agreement with them and the Royals, to let the Wesen Council deal with Grausen.

The problem of over-zealous Grimms likely led to the creation of the Reapers, an order dedicated to eradicating them in a "who watches the watchers?" situation.

At some point the Grimms became aware of the Coins of Zakynthos and their inherent resistance to them; knowledge of the Coins was included in Grimm archives and individual Grimms were encouraged to seize the Coins and keep them safe.

When Europeans began to colonize the Americas, Grimms were present early on to document and defend against the New World's previously unknown Wesen.

By the 21st century, Grimms were feared almost without exception by the entire Wesen community. In Portland, Oregon, a single Grimm, Nick Burkhardt, has become aware of his abilities and seems to be redefining what the Wesen thought they knew about the Grimms.

Nature
Grimms are tasked with policing the creature world, making sure that those who harm humans are stopped. For this reason many Wesen mistrust or fear them, even having their own set of Wesen fairy tales warning Wesen children about the Grimms. Grimms possess superior fighting skills, good heads for observation, and uncanny instincts for people and their personalities, even besides their ability to sense the supernatural. So police work seems a rather good fit, as is law.

In, it is revealed that, although most Grimms broke with the Royal Houses centuries ago, Grimms occasionally work for the Seven Royal Houses and with the Verrat, helping to enforce order among the Wesen. This is another reason why even a sole Grimm can inspire so much fear from Wesen: the prospect of bringing the wrath of a Royal Family upon themselves if they do anything to an enforcer.

Within a single family group, not all members of a Grimm's family become Grimms. In some cases, entire generations can pass without any relative showing signs of their abilities, only for several Grimms to emerge in the same generation. As a general rule, females become aware of their abilities earlier than males. The Grimms themselves, or at least the Kessler/Burkhardt branch of the family, did not know why this was.

Although the majority of the Grimms discussed so far are of European descent, Grimms seem to be found worldwide, as the episode "Tarantella" involves a European Grimm meeting a Japanese doctor with all the abilities of a Grimm on a steamship sailing from Singapore. However, documentation of New World species of Wesen appears to have been conducted by European Grimms. It is not clear if all Grimms are genetically related (though it is implied, as on all occasions Nick's referred to any Grimm in question, as his "ancestors"), and if so, how many generations back the relationship goes.

Grimms seem to have preference for decapitation and there are many references to them cutting off their victims' heads. This tactic has made them so infamous that they have been occasionally referred to as "dēcapitāre" or "one who decapitates" in Latin. This is apparently what they were known in the old days, but has since fallen out of fashion and is now only used by traditional Wesen such as Gelumcaedus.

Powers
Grimms possess many powers, the most used one is their ability to see Wesen for what they really are, but only if the Wesen is startled, scared, angered, stressed or something else happens that disrupts the Wesen's concentration. They are also able to see woged Wesen on film recordings. Grimms have absolutely no influence over this ability.

A woged Wesen can detect a Grimm by looking into their eyes. According to Monroe they can see an "infinite darkness" in a Grimm's eyes that reflects the Wesen's true nature. Nick mentions that none of his ancestors wrote about this trait, and before he learned the answer, he hypothesized that they can naturally sense when he recognizes them. A Grimm's ability to detect Wesen is not limited to sight; Nick has demonstrated the ability to detect the presence of Rosalee Calvert and Andre, despite having been temporarily blinded by the latter. Later, he describes a sort of subtle electric tension in his jaw and forehead when there are Wesen nearby. This "sixth sense" alerts the other perceptory senses, in effect amplifying them.

Due to Grimm's differences in nature, they react differently to Cracher-Mortel spit than other people. The rage stage comes much earlier, and the Cracher-Mortel is unable to control them. They also still possess their Grimm powers making them very dangerous. Never the less, despite being disoriented and confused, they are still calmer and don't just charge at people to attack them like other humans and Wesen under the control of a Cracher-Mortel.

Grimms also possess slightly superhuman strength, durability, agility, reflex, speed, and even morphallaxis. This allows them to go toe to toe with any Wesen, except Siegbarste, and survive things that would kill a normal person. Nick was able take on a Skalenzahne (one of the strongest known Wesen) and defeat it. His aunt, despite dying of cancer, and weakened by the drugs, was still able to kill her human attacker, and showed no fear to Monroe. Grimms' strength can also be measured in the fact they can casually take down Wesen who possess superhuman strength, such Jagerbar's or Klaustreich, and can easily overpower humans. Grimms' durability is particularly notable; several times Nick has shrugged off blows from creatures with incredible strength. For example, when facing a Schakal, the creature smashed a toaster around his head, but he recovered in seconds. . He was even able to escape from a beating with a Siegbarste, with the worst of his injuries being a few bruised ribs.

It has also been shown that the blood of a Grimm can destroy the animal part of a Hexenbiest. In essence, the Hexenbiest becomes human after this and is no longer a part of the Wesen world. It is currently unknown if this will work on other members of the Wesen world.

Grimm also possesses greater resistance to arsenic's druglike effects, and are thus able to resist the effect of the Coins of Zakynthos.

As well as this, Grimms seem to have a natural aptitude for fighting, particularly against Wesen, and with ancient and medieval weapons. They also possess incredible observation abilities and keen instincts. There also seems to be some natural aptitude in the Grimm lines of artistic talent as there are many detailed pictures in Aunt Marie's books from the other Grimms and Nick shows an aptitude for drawing as well. And when blinded, Nick's hearing is enhanced to the point of hearing from far away as Nick was able to hear Rosalee coming and Hank's conversation with Wu on the phone despite being far away. He was also able to hear a fly buzzing on the ceiling and to destroy many thrown fruit with his kanabo when he and Monroe were testing his hearing.

Endezeichen Grimms
Endezeichen Grimms are the worst type of Grimms there is; they are ruthless, xenophobic and sadistic Grimms, who savagely torture and murder Wesen, not caring if the Wesen in question are good or bad.
