Vriska Serket, also known by her Trollian handle arachnidsGrip, is one of the trolls. She was the eighth troll to be introduced, which also refers to her theme and obsession with the number eight. Her handle relates to her in two main ways. One, arachnids, refers to her interest in and fascination for spiders. The Grip part of the handle most likely represents her power to have a grip on someone's mind, or control it. Her associated zodiac sign is Scorpio (♏) and her horns are shaped like a pincer and a stinger.
"Vriska" was suggested by Terin. "Serket" was suggested by Chin Music. Vriska is a shortening of "Vrishchika", the Hindi name for Scorpio, or could be related to "Vṛścika" the Sanskrit word for scorpion, but could also refer to Kalpavriksha, a wish-fulfilling tree below the fourth chakra according to Zentra Yoga. This tree is said to fulfil both positive and negative wishes, again corresponding with the duality of Vriska's personality. Her name could also be a reference to the Planescape: Torment character Vrischika. Both characters are bossy, winged, have travelled throughout several universes, and are associated with the color blue.
Her surname is taken from "Serket", the Egyptian goddess of healing stings and bites, and also the personification of the scorpion. It means both "(she who) tightens the throat", a reference to paralysis caused by scorpion stings, and "(she who) causes the throat to breathe", meaning that Serket was one who could cure scorpion stings and the effects of other poisons such as snake bites. Serket was conflictingly associated with stings or bites and with the cures to such maladies, mirroring the duality of Vriska's personality - she alternates between seriously injuring other trolls and helping them, or at least attempting to do so.
