This is a bithday present to the beautiful ~XxPrivate-LaroroxX!
Sollux Captor, also known by his Trollian handle, twinArmageddons, is one of the Trolls. His associated zodiac sign is Gemini (♊) and he has two horns on each side of his head.
When typing, he doubles all of his 'i's, as well as replacing 's' with '2' and 'to' and 'too' with 'two'. This is meant to convey that he speaks with a bit of a lisp, possibly a reference to the programming language LISP. This duality theme may also be a reference to Binary code, because of his talent at programming.
Alternatively, his comfort with binary and his themes of duality probably link directly to the fact that his symbol is Gemini, the sign of the Twins. Everything he has or does relates to duality, especially his personality.
Additionally, he often will combine two sentences into a single line, but with no punctuation apart from a single period at the very end. Starting on this page, he begins using apostrophes as well. Occasionally, he ends sentences with an all-caps "FUCK", but not to the extent of a typing quirk. However, his teeth are later knocked out, and he begins to talk like Aradia due to losing his lisp. He also has a very strong psychic ability.
Sollux rather transparently divides into "sol-lux", the Latin words for "sun" and "light", respectively. In addition, if you switch the S and P in his name it becomes "Pollux Castor." Pollux and Castor are the two brightest stars in the constellation of Gemini. It is also worth noting that Pollux is a red giant, while Castor is bluish white, complementing the red/blue duality theme. Castor and Pollux were famous mythological twins, which is where Gemini - Latin for "twins" - gets its name. Pollux and Castor were also the names of two characters in the movie Face/Off, a Nicolas Cage flick that came out the same year as Con Air and one that John Egbert has a poster of in his room.
His username, twinArmageddons, reflects two meanings. The first is the fact that he will die twice, and the second being the end of the two universes.
He was on the Blue Team.
His cheeks are supposed to be yellow.
