Facts about Homestuck Trolls!

Vriska

Vriska Serket, also known by her Trollian handle arachnidsGrip, is one of the trolls. 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 types in a cerulean blue font and her typing quirks revolve around the number eight in relation to arachnids (such as scorpions). The letter 'B' and sounds like 'eight' are replaced with the number 8 and some characters are repeated in sets of eight, usually vowels or punctuation marks. When she is flustered, she replaces vowels with an 8 and uses it in nearly every word she types, even in cases where the vowel doesn't match an "eight" sound. Her smilies also have eight pupils. In keeping with this theme, she was the eighth troll to be officially introduced. Scorpio is also the eighth sign of the Zodiac.

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 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.

She ended up as a member of the Red Team after being evicted from the Blue Team by Aradia Megido.
