A Dämonfeuer (alternate spelling Daemonfeuer; DAY-mon-foy-ər (Grimm: DAY-muhn-fyoo-ər); Germ. Dämon "demon" + Feuer "fire") is a dragon-like Wesen that was first seen in "Plumed Serpent".

Characteristics Edit


As depicted in the comic book series.

When they woge, Dämonfeuer undergo one of the more extreme changes of any known Wesen. Their skin becomes a green and scaly hide, their nose becomes flat, their eyes take on a fire-like appearance, and most notably they grow a large crown of horns on their heads. Males possess a larger set of horns and have more angular faces than females. Despite rather extensive transformation, Dämonfeuer still retain physical traits of their humanity mainly their ears and hair which remain largely unchanged.

Dämonfeuer are much stronger than humans, and are at least as strong as Grimms. However like humans, their strength seems to more-or-less differ by gender. Their strength and durability seems to be greatly diminished in human form, since Juliette was able to knock Ariel down with one hit. This only seems to apply to females, though as Fred was able to fight Nick in his human form. Male Dämonfeuer are incredibly physically powerful, as the elderly and sickly Fred Eberhart was able to fight Nick on an equal level, and even knocked him down twice, despite Nick being much younger.

Fire and smoke productionEdit

Fred Eberhart Morphed

The diet of Dämonfeuer consists mainly of humans. This fat-rich but low carb diet induces higher levels of gastric acid production, crucial for digestion within the stomach.

The production of too much gastric acid results in frequent heartburn. If the gastric acids spill into the lungs, this induces coughing, which is the body's way of ridding the lungs of the acids that settle in them.

Dämonfeuer take heartburn to a whole new level with their unique ability to convert fat through ketosis into a highly combustible acetone vapor, mixed in with the gastric juices that spill into the lungs, leading to laryngopharyngeal reflux. Thus, when a productive cough is expelled, the combustible vapor is sprayed from the mouth. Following a series of vapor-releasing coughs, a single productive cough releasing gastric juices from the lungs is enough to ignite the gas, and giving the appearance of fire expelled from the mouth.

Fire production.

This fiery breath causes anyone in its path extremely severe burning, and death to anyone who it hits. Their fire has been compared to napalm, in terms of heat and destruction, and is enough to melt metal and burn humans to a crisp in seconds. Dämonfeuer seem to have two forms of fire breath. The first and most used form is slowly releasing the vapor and after making the air thick with it, igniting the vapor. The other version is a quick flamethrower style attack, where the Dämonfeuer just opens it's mouth and breathes fire, like a typical dragon. They also seem to have a natural resistance to heat and fire. However, as Fred Eberhart's face had been burned in a house fire, it appears they are not totally invulnerable.

Behavior Edit

Copper wire

Obsession for copper

Dämonfeuer are treasure-mongers although, in modern times, they have abandoned gold and jewels, instead collecting large amounts of copper of which they are very possessive. They have no qualms with stealing copper to increase their horde.

Due to their might, Dämonfeuer are not afraid of Grimms. Dämonfeuer also don't seem to harbor any hatred toward Grimms, despite the fact that Grimms have long hunted them. In fact, it appears Grimms are somewhat of a curiosity to Dämonfeuer, as Ariel Eberhart hinted that she had always wanted to see a Grimm up close.

Dämonfeuer, or at least male Dämonfeuer, seem to be a martial race, and have a value for combat, and see death from combat or in battle, as to die with honor and dignity. As such, they are commonly soldiers and sometimes war heroes. They also take pride from the memory of their relatives' services. For this is the reason they sometimes capture warrior’s lovers, so that the warrior would come to face them, and they would be able to fight to the death. Females also see this as an honorable death, although their idea of how they should die appears to differ. It is this which is the basis for the myths of dragon quests. This martial nature means that Damonfeuer are greatly ashamed when they fail to save their mates. Fred Eberhart was traumatized by the death of his wife, and his daughter, Ariel, was very disappointing in him, stating he should have protected her. The children of Dämonfeuer are always fiercely loyal to their parent, going to extreme lengths to help them and sometimes committing suicide upon the death of one. Dämonfeuer have a habit of making their lairs in caves.

Perhaps due to their nature, Damonfeuer are fond of occupations involving fire. Fred Eberhart was a welder, his daughter Ariel was a fire dancer, and his father wielded a flamethrower in World War II.

According to Monroe, the best way to fight them is with a lance. Guns can't be used, as they would ignite their vaporized fat, which would cause an explosion.

Excerpts from Grimm DiariesEdit

In Aunt Marie's book, there is a story about a Dämonfeuer in medieval times.

Below are three excerpts taken from the journals:

The Dämonfeuer, a dragon like creature I began tracking many years ago, has a fierce appearance, but an even more frightening secret power.

I watched my dear companion Otis burn to dust before my very eyes as this horrific creature spat some kind of mucus on him and coated him head to toe. The substance was highly flammable. Otis didn't stand a chance.

Though his fire was hot ... strength incredible, our men were many and well-trained in combat. With their metal suits of armor, they were able to fend off the dragon, pushing him deeper and deeper into his lair beneath the mountains.

When we finally reached the deepest part of the lair, we could see the fair maiden struggling against the straps that bound her.

The men and I watched as the creature threatened to kill her right before our eyes, but we soon realized that he was using her simply to bait us into battle.

Tired of the Dämonfeuer's games, the men ended the long battle with an impaling stab and a final (?) to the neck.

After Otis's death, we tracked the Dämonfeuer (sic) from village to village. In each town he would collect and (sic) precious metals, jewels, or iron he could pillage from the people.

We were several days behind him when we came to a village that had been completely burned to the ground. Only a single child remained to tell the tale.

The boy told us that the Dämonfeuer had not been alone. His own offspring had helped him to attack the village. They packed away all the metal in canvas sacks or grain bags. The child overheard a younger Dämonfeuer say that the metals would help to give their father strength and power.

My party moved on from the village, following the burned trail of destruction.

Finally on the fifteenth day, we caught up with them hiding out in a temporary lair in the lower foothills outside Wohl village. One of our men did battle with the Dämonfeuers in an attempt to regain some treasures, but was pushed back by the fire-breathing heathen.

The Dämonfeuer are able to breathe fire by converting fat through ketosis into a highly flammable Acetone. They're also treasure-mongers, and are very possessive of the large amounts of copper they're known to collect.

We followed the Dämonfeuer high into the mountains where we discovered his terrible lair, filled with treasure stolen from all the villages. The bones at the entrance to the cave were too many to count. If we didn't know better, we would have guessed it was the entrance to hell.

The author of the latter story stated that the Dämonfeuer was the fiercest of them all.
