Fairly cranky, he appears to hold long-suffering grievances over how often his allies depend on him. Much like Vriska, Sollux has a number of quirks in how any text used by him is presented. Namely, his text is always bold and underlined without added colors. In a strange way of showing his lisp, Sollux always types "i"s in pairs; replaces his "s"s with "2"s; and spells the words "to"/"too" like the number is spelled: "two."
