A Murciélago (Mur·cié·la·go; Span. "bat") or Geölterblitz (geh-ØL-tur-blits; Ger. "greased lightning") is a bat-like Wesen that appeared in "Happily Ever Aftermath".


When woged, they have glowing red eyes, leathery brown skin, bat-like features, sharp claws, webbed 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, Murciélagos also possess razor sharp claws that they use as secondary weapons. Blutbaden refer to Murciélagos as Geölterblitz, meaning "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." ("Happily Ever Aftermath") The best way to fight a Murciélago is to use a hand-crank siren known as a Murciélago Matraca, which emits sound waves that temporarily render the Murciélago incompetent, as Murciélagos possess keen, bat-like hearing.

Murciélagos 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.


Murciélagos seem to have more extreme emotional levels; they can be calm and creative, producing masterpieces such as Spencer's painting in the beginning of "Happily Ever Aftermath", or they can be selfish, spiteful, and caring 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 DiariesEdit

Matraca Murcielago
(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.

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.

Season 1 Blu-ray Grimm Guide ProfileEdit

A hideous bat-like creature, a Murciélago features glowing red eyes and vicious rows of teeth when morphed. It has the ability to emit an ear-splitting sound (similar to the way bats see in the dark) that causes glass to shatter, blood to come out of a person's ears and nose, eyeballs to burst, and all sorts of other bodily damage. It is best to face off against one by using a hand crank siren known as a Murciélago Matraca.



  • Murciélagos 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 was the first species name in Spanish.
