Help Me Name a Demon

I’m working on an urban fantasy series at the moment and one of the villains is a demon. I’ve been using the name Ashbel but I don’t know, something seems off with the name – Ashbel doesn’t sound heinous enough. Or does it?

What do you think? Do you have a perfectly wicked name for me? Let me know in the comments if you think Ashbel sounds like he could be a big bad demon or if you have a better naming option.

If I use the name you submit I’ll add you to the book’s Acknowledgements page and you’ll own bragging rights to naming the series’ malevolent villain.
