Names to Run Away From Really Fast/Names Ending In Th

Need a scary and ominous sounding name? End it in "th".

For some reason this trope seems to be quite common in English-speaking fiction. Maybe it's because Names to Run Away From sound mysteriously ancient (due to this trope's prominence in some Ancient Dead Languages: e.g., in The Bible) or ominously foreign, maybe it's the sinister hissing sound itself... Whatever may be the case, Names to Run Away From is a sure-fire way to let your audience know: this person/place/artifact is to be feared.

It's usually used to denote: Sometimes a partial aversion takes place, and we get something from the aforementioned list (e.g., something ancient) that isn't terrifying or evil.
 * something so ancient it sends chills down your spine;
 * something related to:
 * demons;
 * Eldritch Abominations;
 * gods (most often those who aren't so different from demons or Eldritch Abominations);
 * dark and forbidden magic.

Anime and Manga

 * Bokurano: The kids who pilot it didn't intend to give it scary name, but considering the context of the story, Zearth fits this trope to a T.

 * Bernadeth of the New Gods. Guess what she does.
 * Marvel Comics:

 * Malekith the Accursed, a supervillain, ruler of the Svartalfar (Dark Elves).
 * Doctor Strange comics have a lot of those:

Literature

 * The Trope Codifier here may be H.P. Lovecraft, who liked this trope a lot:
 * Asenath Waite, from The Thing On The Doorstep. She's perhaps the only human in Lovecraft's works who got a Name Ending In Th... and that says a lot.
 * Azathoth, the Blind Idiot God. A gigantic Eldritch Abomination, that once was a demiurge, but nowadays just dwells somewhere in deep space listening to music.
 * Innsmouth, the titular place from Shadow Over Innsmouth. Even though the name is English in origin, the "th" at the end hints that something is fishy about this place...
 * Kadath, from The Dream Quest Of Unknown Kadath. It's the last dwelling of the gods, inaccessible to mere mortals.
 * Sarnath, from The Doom That Came To Sarnath. A forgotten ancient city, that, well...
 * Shoggoth, a type of creatures looking like a giant formless puddle of black goo with a lot of eyes.
 * Shub-Niggurath, the Black Goat with a Thousand Young. One of the most well-known Great Old Ones.
 * Yith. Home planet of The Great Race of Yith, a powerful alien race capable of swapping minds with creatures of another eras.
 * Yog-Sothoth, aka the Key and the Gate, and The All-in-One and the One-in-All. A powerful cosmic Eldritch Abomination who looks like "a congeries of iridescent globes" that is essentially an embodiment of... well.. everything. As in, all of space and time and the entire multiverse.
 * Yog-Sothoth and Azathoth even have an additional "th" in the middle!
 * Yuggoth, aka planet Pluto. But it's more terrifying than it sounds, since in Lovecraft's works Yuggoth is inhabited by all kinds of Eldritch Abominations.
 * Cthulhu is perhaps Lovecraft's most famous creation, a very good reason to run away very quickly from this Great Old One, is that he/it is able to drive anyone that so much as looks at him/it into pure insanity.
 * More Names to Run Away From appeared in the works of other Cthulhu Mythos authors:
 * Abhoth
 * Daoloth
 * Ghroth
 * Nug-Soth
 * Planet names include Abbith, Haddath, Kynarth, Xoth, Yaddith and Zaoth.
 * The family tree of Tsathoggua, an Old One, includes such names as Cxaxukluth and Ghisguth. Also, Tsathoggua himself lives on a mountain called Voormithadreth.
 * The creator of the term Cthulhu Mythos, Lovecraft's associate and horror author August Derleth, even had a Name Ending In Th himself!
 * Averted in JRR Tolkien's works: words and names ending in 'th' are quite common in his Con Langs, and there are both evil and good ones ending up with such a name. (e.g. Morgoth vs Elbereth)
 * Discworld:
 * Yob Sodoth (a parody of Yog Sothoth), mentioned in Pyramids.
 * Star Wars Expanded Universe:
 * Abeloth.
 * Also, names mentioned in Film entry for Star Wars.
 * Dragonriders of Pern:
 * A partial aversion. All dragon names end in "th". While their fearsome appearance has been used to intimidate on at least one occasion, Pernese dragons are depicted as generally friendly and would never knowingly harm a human. (Except at hatching, and that's usually due to unfamiliarity on the part of at least one of the involved parties.)
 * Sword of Truth:
 * Mord-Sith, an all-female order of inhumanly sadistic torturers. (Gaelic for Death Faerie, slightly less terrifying to those who don't know anything about Gaelic or Celtic mythology, ten times as horrifying to those who do.)

 * The Gelth, from The Unquiet Dead.

Mythology/Religion

 * Scottish folklore:
 * Wraith, a type of ghost.
 * Sith (pronounced shee) is Gaelic for fairy (being derived from Sidhe). Not to say that you shouldn't run away real fast, as Sidhe are known for being cruel pranksters and kidnapping people and livestock.
 * The Bible and related sources have a lot of this; the reason for this is that many Hebrew words end in the letter tav, as it is a marker for feminine gender (both in the singular and in the plural form -ot). The -ot version is particularly common, thanks to the pluralis excellentiae, i.e. "calling the singular thing plural to emphasize how awesome/terrible (classical sense) it is". In Biblical Hebrew, final tav was pronounced -th, which morphed to -s in Ashkenazi and -t in many Sephardi/Mizrahi dialects (which eventually became the model for Standard Hebrew).
 * Demon names, which include Astaroth, Balberith, Berith, Bileth, Lilith and Obizoth.
 * Goliath, a Philistine champion of Gath and all-around badass "whose height was six cubits and a span". During a war he issued a challenge to his enemies: King Saul and the armies of Israel, and he instilled fear in all of them.
 * Behemoth, a monstrous creature mentioned in the book of Job.
 * The Qliphoth, evil beings from Jewish teachings (e.g. the Kabbalah). They include the Gamchicoth (Devourers) and Nehemoth (Whisperers).
 * Alchemical and occult sources:
 * Azoth, a mysterious substance sought by some alchemists. Aleister Crowley mentioned it in some of his works.
 * Egyptian Mythology:
 * Seth (or Set), an evil chaos god and the murderer of Osiris.
 * Thoth, the god of knowledge and the moon. His name consists of nothing but 2 "th"s separated by a vowel, and his head was that of an Ibis (which most people won't recognize and is only one letter away from Iblis).
 * Neith, a goddess of warfare, hunting, and weaving (in fact, her name means "weaver"). She eventually also came to be considered a goddess of creation.

The yugoloth leader is called an Oinoloth. One notable yugoloth (an arcanoloth, to be exact) is named Helekanalaith.
 * Some monsters that aren't particularly scary: koalinth, kapoacinth, quaggoth.
 * Some of the nobility of Hell were given the names of demons from Jewish/Christian/occult sources (see ).

 * Mammoth. Just ask your Ice Age ancestors.
 * Or perhaps you should ask the mammoths about said ancestors--they were probably more scared of humans than the other way around, given that we snacked on them to the point of extinction.
