This is my mercury-themed #fantroll for an RP I'm planning, which will be called Sbutt.

Her name comes from hydrargyrum, an old word for mercury (the element). Her symbol is one of the lesser known alchemical symbols for mercury, since the most common one is used for a lot of fantrolls based off the planet Mercury. There's a lot more little details, but I'll run out of room. She does have a good reason for being a mutant blood though, which is normally something I would avoid.
