Murciélago

A Murciélago (pron: Mur·cié·la·go; Spanish: "bat") is a bat-like Wesen that appeared in.

Mavis Kerfield is getting ready to go to bed when she hears something moving underneath her bed. Looking under it, she is slashed across the cheek by a creature with glowing, red eyes and runs. She's cornered at the balcony of her staircase when the creature releases a supersonic scream, shattering all of the glass and causing Mavis' eyes, nostrils and ears to bleed, and Mavis falls over the balcony, dead.

When Nick and Hank bring the news of Mavis' death to Spencer Harrison and Lucinda Jarvis, Spencer woged in agitation, revealing himself to be a Murciélago.

After Arthur tells Spencer that Lucinda left to visit her step-sisters, Spencer immediately goes after her.

Tiffany Kerfield is getting out of her house when Lucinda suddenly meets her. Tiffany scornfully accuses her and Arthur of murdering Mavis and gets in the car. Lucinda then goes in front of her car, woges into a Murciélago and emits a supersonic scream, killing Tiffany the same way Mavis died.

In the trailer, Nick and Monroe find an entry on the Murciélago, which a Grimm encountered while in the Amazon rainforest. They then find a Murciélago Matraca, which produces the same sound as a Murciélago but as a directional force, negating the Wesen's screech.

When Spencer arrives at Tiffany's house, he finds the ruined car an Tiffany's body, and is arrested by Nick. He realizes Nick is a Grimm when he whispers to Spencer that he "knows how he kills". In custody, Spencer tells Nick and Hank the truth of what he is; that he was able to produce a supersonic screech capable of breaking glass and popping blood vessels and ear drums, and admits to the murders of Tiffany and Mavis. After Hank leaves the room, believing Spencer is trying to build an insanity case, Spencer reveals to Nick that it was, in fact, Lucinda who killed the Kerfields, and that she was always kept in check when she got what she wanted. What Nick leaves the room, Spencer screams his high-pitched screech and breaks the window, escaping.

Spencer returns to the Jarvis residence, where he finds that Lucinda was already gone and finds Arthur with claw marks on his face from Lucinda.

Lucinda is already in Taylor's house while Nick is calling her step-sister, and proceeds to chase her in an attempt to kill her, taunting Taylor with childhood memories of always being caught during hide-and-seek and that she can't hide. When the police arrive, Lucinda escapes into the garage with Nick in pursuit. Monroe then brings Nick the Murciélago Matraca from the trailer, which Nick uses to smoke Lucinda out of the garage.

Outside, Lucinda runs into Spencer, and asks for his help. In response, Spencer woges and screams into Lucinda's face, presumably killing her. After he makes a sad goodbye, Lucinda reveals herself to have stayed alive long enough to grab her godfather and rip out his throat, killing them both.

Characteristics
When woged, they have glowing red eyes, leathery brown skin, bat like features, sharp claws, webbed-like hands, and vicious rows of teeth. They have the ability to produce a sonic shriek that is fatal to humans. The shriek shatters eardrums, pops eyeballs, ruptures nasal passages, and explodes bowels. In addition to their sonic shriek, Murciélago also possess razor sharp claws that they use as secondary weapons. Blutbaden refer to Murciélago as Geölterblitz "bat out of Hell" (lit. "oiled lightning") due to the fact that a Murciélago's screech is particularly harmful to the sensitive hearing of a Blutbaden. As Monroe puts it, it can "peel the bark off a dog". The best way to fight a Murciélago is to use a hand-crank siren known as a Murciélago Matraca, which emits a noise that temporarily renders the Murciélago incompetent, as Murciélago possess bat like hearing.

Murciélago are more agile than humans, able to walk away after jumping out of a two story window onto solid concrete, with no visible wounds. They are also more resilient to their own scream attack; it will kill them, but it takes longer than it does with humans, and even after suffering the wounds they still remain alive for a few minutes. They do not appear to be any stronger than normal humans, but they are quite fast and agile.

It's worth noting that Lucinda Jarvis' hair turned from blonde to black when she woged. It's unknown if this happens to all Murciélagos, or just females.

Behavior
Murciélagos seem to have a more extreme emotional levels; they can be calm and creative, producing masterpieces such as Spencer's painting in the beginning of, or they can be selfish, spiteful and care only for themselves, as seen with Lucinda's murderous hatred for her step-family and her apathy for her husband that could only be tamed when she got what she wanted.

Excerpt from Grimm Diaries
(In Spanish by Jose María Lopez Diego y Grimm) "Llegué a América del Sur ya hace seis meses, siguiendo la pista de un Murciélago que se embarco en un buque de vapor en Málaga después de haber cometido una serie de asesinatos.

Lo seguí hasta la selva de las Amazonas donde parece que toda criatura tiene los dientes afilados- incluso los peces.

Aprendí después de haber examinado a las víctimas del Murciélago que estas criaturas producen un sonido tan agudo que puede matar a cualquier hombre, mujer o bestia en segundos.

El sonido puede hacer añicos de los tímpanos, explotar los ojos, reventar a los pasajes nasales, estallar a las tripas, y causar muchísimo daño interno. ''En mis batallas, he descubierto que muchas veces uno tiene que pagar con la misma moneda, y, como sospechaba, los sonidos fuertes pueden debilitar a un Murciélago. Por lo tanto, diseñe una sirena que, a todo poder, emite un sonido tan agudo que a los humanos es imperceptible. El sonido emitido de la Matraca Murciélago desorienta a las ondas ultrasónicas del Murciélago, negando a su habilidad de crear su propio sonido destructivo''."

Translation: "I arrived in South America already six months ago, following the trail of a Murciélago that embarked on a steamship in Málaga after it had committed a series of murders.

I followed it until the Amazon Rainforest, where it seems that every creature there has sharp teeth, even fish.

I learned after I had examined the victims of the Murciélago that these creatures produce a sound so sharp that it can kill any man, woman, or beast in seconds.

''The sound can shatter eardrums, pop eye balls, rupture nasal passages, blow out bowels, and cause significant internal damage. In my battles, I have discovered that many times one does have to pay in kind, and as suspected, loud sounds weaken the Murciélago. Therefore, I'm designing a siren that at all power, beeps so acute that it is imperceptible to humans. The sound emitted by this Murciélago Matraca disorients the Murciélago with ultrasonic waves denying its ability to create its own destructive sound.''"

Trivia

 * Murciélago originate from South America.
 * The name Monroe calls them, "Geölterblitz", comes from the German idiom "wie ein geölter Blitz," which literally translates to the English idiom "like greased lightning". Synonymous with that idiom are the English idioms "like a blue streak" and "like a bat out of hell," as they all describe something that is very fast or sudden.
 * Murciélago is the first species name that is Spanish.
