Names to Run Away From Really Fast/Adjectives

Names to Run Away From Really Fast which inspire fear because they are fearsome adjectives: Vicious, Grim, Sinister, Nefarious, Horrible, etc.

Or they inspire mistrust because they sound "false", like "honest".

Literature

 * Vishous from J.R. Ward's Black Dagger Brotherhood novels, mercifully shortened to 'V'. Most of her male characters have bizarrely spelled "badass" names, including Torhment, Phury, Zsadist, Rhage, Rehvenge, and Wrath (well, that last one is spelled correctly). John Matthew doesn't fare any better with his warrior name:

Music

 * Count Nefarious from the PC game Toonstruck.

Music

Film

Anime and Manga

 * Yu-Gi-Oh has several instances:
 * Yami (= Dark) Yugi, whose early punishments for people who attacked or threatened his friends included tricking people into yoyoing themselves through a roof to fall several stories, getting people stung by their own scorpions and subjecting people to illusory torture by Eldritch Abomination.

"Cecile" comes from "caecus", which means "blind" in Latin. In olden times it implied powers of prophesy as well, since many famous seers (Tiresias for example) were blind.

 * Many villains in the Redwall series have such names as Cluny the Scourge, Slagar the Cruel, Ferahgo the Assassin, and Gulo the Savage.

Real Life

 * Johnny Rotten (real-life: John Lydon), band leader of the Sex Pistols. Given that 'Johnny' is British slang for 'condom', that verges on Squick, too.
 * Adam Savage from Myth Busters: His job involves smashing, blowing up, or otherwise destroying various items in big and spectacular ways (and he is very enthusiastic about his work). Also, in episodes where the crew play out character roles, Adam often plays villainous characters with "Savage" somewhere in their name (i.e. Baron von Savage, Captain Redbeard the Savage).
 * Colm Meaney an Irish actor who is actually by many accounts a pretty nice guy. Doesn't help that outside of Star Trek fandoms he's mostly known for playing villains or at the very least hard-assed Anti-Hero types.
 * Ivan the Terrible. He was a good ruler early on, defeating many enemies of the Russians, earning him the nickname which could also be translated as "formidable" or "fearsome". Later on, he became The Caligula, making his name scary but appropriate on a whole different way.
 * There is is a Zimbabwean footballer (soccer player) called Danger Fourpence.
