Viperine Gorgon is a a 2013-introduced and all-around character. She is a gorgon from Barcelgroana, Spain and a makeup artist employed at Hauntlywood. Specifically, she is the personal makeup artist of Elissabat, star of the Vampire Majesty series of movies. Though she usually works with the rich and famous, Viperine just as glady goes to elder monsters' homes to do makeovers for the residents. As long as she can be active with makeup, she is satisfied. As the daughter of Stheno, Viperine is the niece of Medusa and Euryale and thus the cousin of Deuce. The two rarely see each other but for the summer vacation, which the Gorgons yearly spend together on Petros Island. Viperine in particular is an affectionate person, though she has the unfortunate habit of showing care by biting others.
- In English, she is voiced by Yeni Alvarez.
Viperine is a girly girl, which is why she's pursued a career as make-up artist. She loves to talk but is also a good listener.
Viperine has pink and white hair among which seven snakes grow. She has yellow skin and pink eyes, and scales like Deuce, though hers are pink and located on her lower forehead between her eyes. Viperine dresses in a bohemian way. She wears all pastel colors with only some black.
She is the daughter of Stheno, whose sisters Medusa and Euryale are her aunts. Deuce Gorgon is Viperine's cousin.
