Helsa Von Eldritch

Helsa's appearance is that of a tall and hourglass-built demon with green-smoke skin, and long silverish-white hair that sports dark gray spots, similar to a cephalopod's tentacles. Her hair also features rather large bangs which covers her right eye.

Her eyes themselves have neon-green irises, deep-teal sclera, slit pupils, and have thick upper eyelashes with smaller bottom lashes protruding from them. Her mouth sports black lips, and sharp neon-green teeth inside.

Helsa wears a brink-pink coat with a neon-green fur collar and cuffs, as well as four neon-green buttons on the front, a greenish-black skirt with the same trimming as her coat around the bottom, and over-the-knee greenish-black heeled boots.
Full Demon

When she enters her full demon form, as shown when she became enraged because Charlie called her a loser during her song, she grows a more eldritch appearance with sharp-toothed mouths and eyes popping out throughout her body.

Helsa is described by Vivziepop as a "mean rich girl",[2] with a personality similar to Regina George from the movie and musical, Mean Girls,[3] as she is purposefully and deliberately mean to others. This was further supported by Faustisse, who described her as the "very smart kind of evil".[note 3]
