Sollux is a weird and abrasive troll with powerful psychic abilities, he lives in a large apartment building but has to keep his lusus chained to the roof due to how large it is, as a double headed giant. He talks with a lisp and has a tone of voice that sounds irritated. Meeting Sollux for the first time, when you mention Karkat and Terezi, visibly is sick to his stomach. Although soon after learning about his problems of voices in his head, you grow close in order to help him work it out.
