Other: Leader of her two woman army (Ariadne and herself), loves the Hotlands and Snowdin, not to much of a fan of Waterfall since she's afraid of the water. She acts very fearless when in reality she has many fears:
• loneliness
•the dark
•woods
•paranormal (like ghosts, and demons)
•moths and butterflies (why?)
But she's completely fine when seeing
•a corpse
•blood
•people afraid of her
•people afraid in general
•love
•spiders, pretty much every animal expect butterflies and moths
•Bad Time Sans
•Anything, and everything horrific (expect the paranormal)
Also she and Ariadne are usually matching in clothing, but not in color, like this:
