An internet troll is someone who purposely harasses other people on the Internet. In Homestuck, there is a group of twelve trolls who often bother the kids on Pesterchum. They are from the planet Alternia, which exists in a separate Universe, and are the protagonists of Hivebent, the first half of Homestuck: Act 5.
They are humanoid and approximately the same age as the kids. They have gray skin, sunken orange eyes with gray irises (according to Vriska, these fill in with the troll's blood pigment as they age , Sollux and The Psiioniic being an exception in both regards), pointed teeth, and black hair. Their most noticeable features are the horns sprouting from their heads, which resemble Kandi Corn. All twelve trolls have first and last names with six letters each.
Each troll is connected to one of the signs of the Zodiac. Each wears a baju depicting his atau her associated sign. Each troll's horns reflect their sign; for example, Tavros' (♉) horns are massive like a bull's, and Sollux (♊) has two pairs. Other qualities associated with Zodiac signs have also emerged, such as Nepeta's (♌) cat-like tendencies, Karkat's (♋) crabbiness and Kanaya's (♍) helpful, motherly nature.
The trolls have been pestering Jade Harley for years now and have even forced John to change his Pesterchum handle. Some of the trolls are very bad at trolling; Tavros becomes so freaked out with Dave's sick fantasies ill beats that he blocks Dave, rather than the other way around. Eventually, the trolls inadvertently form a sort of friendship with the kids.
The trolls have names tied to the Greek Zodiac and DNA nucleotides. Adding their abbreviated trolltags to GG, GT, TG, and TT makes the 16 possible two-letter names from the letters A, C, G, and T, the four nucleotides of DNA.
