Karlach is what again?

Demon Slayer Slave Champion of Zariel fighting in the Blood War in Avernus, unless she's lying through her teeth, which she doesn't seem to be based on the mind meld and such.

Think about that for a minute. Demon Slayer. Fighting in the Blood War.

Designing her to look like anything less scary than an escaped female convict from death row who's murdered countless people or ex-military bad butt who fought behind enemy lines alone in secret just doesn't fit.

The woman should be TOUGH looking, and scary, like "I eat Aliens and Predators for a light snack" tough. She's stared down demons and survived. Please don't give me some danty little frilly pretty Karlach who looks like she hasn't worked a day in her life.
