Suggestions for an evil/dark sounding name?

Question

I recently created a character to use in roleplays, but now that I'm at the naming part, I'm stuck.

My character is a half dragon, so she's capable of becoming a full dragon. I've tried looking for any draconic names without using ones from famous dragons, but none are to my liking.

She also possesses the ice element, and her personality reflects on that. So she's quite cold, stubborn, dark and 'evil', if you will.

This is the sketch of her, if her appearance will help towards finding a name for her.

Answer 1

Supreme Underlord of Darkness

Answer 2

Aisu Ryuu (or some variation... it's japanese for dragon and ice)
