Vriska

Skin. Pale gray—typical for trolls.
Hair. Long, black, with a noticeable shiny sheen and a little disheveled.
Horns. Yellow, slightly curved. Each has its own detail: one horn has a claw-like element at the end, while the other has a barb pointing outward. Overall, the shape of the horns alludes to a scorpion's stinger—part of the character's overall scorpion theme. Eyes. There's an important detail here. Vriska wears round glasses with dark frames. Her right eye is fully visible: yellow sclera and a normal pupil. But her left eye is hidden behind a tinted lens—this is how she disguises her peculiarity. Her left eye used to have eight pupils (one central and six small ones surrounding it). This peculiarity gave her the ability to see "eightfold"—for example, through objects. She later lost this eye in an accident. Fangs. Vriska has pronounced fangs—another reference to her "spider" and scorpion theme.
Lips: Full, azure-blue.
Hands. The right hand is normal. But the left is mechanical, a prosthesis.
Clothing. Vriska's basic style is fairly casual: a black T-shirt (often featuring a blue Scorpio symbol—a nod to her zodiac sign), blue jeans, a gray jacket, and battered sneakers. On the other hand, her behavior is highly ambivalent. She can be caring and cruel at the same time. For example, she can take control of other trolls' minds (but only those who are impressionable or insecure), sometimes attempting to "help" them, albeit in a manipulative manner. Vriska is prone to impulsive reactions: if angered, she can lash out. Another trait is a tendency toward perfectionism and obsessive patterns: for example, she can obsess over making sure all repeating patterns match the number 8 and become extremely upset if something doesn't add up. She also envies others, such as Terezi, for her ability to manipulate people without using psychic powers.
