Dark, evil, goth usernames?

Okay, first of all, this isn't for me, it's for a story I'm writing. I really need help. I need to find the perfect goth or goth-esque username for a character of mine. I was thinking something simple - a single word with a lot of meaning. The character having the username is very fiery, intense, mysterious and intimidating. I have had a few ideas so far :

Insulux
Viscera
Silious
Lucretea
Pentacle
Dementia
Elegia
Libidinous
Blodwy
Cocytus
Erebus
Sultry
Envy

I was wondering what you all think of these. What kind of impression do they give off? Which ones do you like? As you can see, they're all single words, to keep things simple, but that's not totally necessary. The character is also clever, so a play on words would be great. Feel free to suggest your ideas. Please do. Nothing like FallenAngel or VelvetSorrow, though, because those are so tacky.

I'd steer clear of using 'Dementia' as a name, that's actually a psychological disorder that old people get.

Out of all those I'd go with Pentacle or Viscera.
I'm not sure about goth names though. Maybe something from a line in a song by a goth band?

Thanks!

Cruella De Vil

"Dementia" reminds me of Delerium

I was actually thinking of that, but I don't know, since it's already the name of a character. If someone could come up with a clever play on words involving Cruella De Vil I'd probably use it. Thanks, though.

How about Bella Swan? jk

How about some variation... Louis Cyphre (but also a character)....

Louis C de Vil...

Cruella L. Cypher...

That's an interesting idea.

Or She-beast?

I kind of like that, actually. She-Devil, too.

Mooey-Moo The Gorgameth

I can't tell if you're being serious.
