They’re not trolls! They’re the Lusii!
- scarvenrot, Guidestuck FAQ

In Homestuck, a Lusus Naturae (or a Custodian) is a large animal, colored entirely in white, who looks after a young troll. Each of the twelve main troll characters has a Lusus.

In Guidestuck, these Lusii become trolls that message Quinn, Jaspers, Cal and Bec, and the trolls become their Lusii.

Known LusiiEdit

Ocerus / poseidonsCoronationEdit

Often roleplays with Quinn, where she pretends she's Princess Quianna and he pretends he's a merman named Otto. Cal is also into this game, as Princess Calypso. He types in Eridan's color, and adds a tilde after each v and before each w.


Participates in a long conversation with Jaspers, warning him not to fuck up the prototyping process which created Jadepuppysprite. Needless to say, Jaspers fucks up anyway. He types in black, uses no quirk apart from the lack of periods, and "chides" people instead of "trolling" them.

Wyvern / twistedAcquittalEdit

First Lusus to appear in Guidestuck. She messages Bec, warning him not to play Sburb Omega, however, she fails and realizes the timeline is doomed. She uses Terezi's typing quirk and color.

Stheno / gorgonsTemptationEdit

Referred to by brokenCaballus as Lady Serket. Replaces s with §. Associates with Bec.

Aurthour / brokenCaballusEdit

Replaces o with O->. Calls all his fellow Lusii "Misters and Misses". Associates with Quinn.

Cappra / archaeologicalGrifterEdit

Replaces a with @, uses sheep puns. Replaces all "you" and similar sounds with ewe. Associates with Jaspers.

Falkor/ ceaselessDreamsEdit

Types in Gamzee's purple. Only puts ★STARS★ around his nouns. Capitalizes only the word "I". Also emphasizes by repeating letters. Lacks punctuation anything further than a apostrophes, often contracts or abbreviates ("sayin", "I'ma", "wanna") words. Has the tendency to say "nehhh", the number of each letter varying according on his distaste. Uses e v e and e ^ e emoticons.

Dardan Vantas/crustyAttitude Edit

Types in gray and in ALL CAPS. Begins and ends each line with a "(\ /)" symbol, followed (or preceded at the end of the line) by an exclamation mark (\ /) ! LIKE THIS ! (\ /) to represent a crab's pincers and stalks. He is overly dramatic and apologetic. He is the latest lusus introduced, last seen trying to help Quinn.
