Alpha Trolls

Trolls are a race of aliens in Homestuck (Hivestuck in this case) from the planet Alternia, which exists in a separate universe. Hivestuck, for tyhe record, is in an alternate timeline, that has nothing to do with the Homestuck Trolls, etc.

They are humanoid and approximately the same age as the kids (13). They have gray skin, sunken orange eyes with gray irises (according to Vriska, in Homestuck, these fill in with the troll's blood pigment as they age , Sollux and The Ψiioniic being an exception in both regards), pointed teeth, yellow nails, black lips, and black hair. Their most noticeable features are the horns sprouting from their heads, which resemble candy corn. All known trolls have first and last names with six letters each.

Each troll is connected to one of the signs of the Zodiac. In this case, they are connected to one of the Astrological Symbols (On the right)

Each wears a shirt depicting his or her associated sign. Each troll's horns reflect their sign; for example, Saskio's look like the to horns on her symbol.

The trolls have online handles 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 G, C, A, T,  the four nucleotides of DNA
