Lusii

Lusii are the beast guardians that trolls have. They keep the trolls safe and protect them instead of adult trolls. While in Homestuck, each lusus (besides that of Aradia) was prototyped, CaNWC's Lusii play a much more minor role.

Aradead's Lusus
Aradead's lusus is a ram or sheep-like beast that was killed by Vrasky when Aradead disobeyed her.

Bicyclops
Sollecks' lusus is a large cyclops with two heads seen chained up to the roof of his hive. He doesn't seem to be relevant but is the only lusus shown to have made it into the session alive with the possible exception of Petpeta's.

Crab Father
Kraket's lusus is a large crab that shares his mutant blood color. Kraket kills him and cooks his body, leaving several cooked parts behind. When Terexi enters the game, she prototypes the Claw but it is soon absorbed by Aradead.

Petpeta's Lusus
Barely seen at all, Petpeta's lusus is a double-mouthed cat.

MomiGrub
Kanaya's Lusus is a six-legged moth-like creature. The MomiGrub is fed the piss-buckets for every troll in all 4 concupiscent quadrants. This presumably gives the MomiGrub the genetic material to create the Momiorb, a spherical egg that has the potential to give birth to many baby grubs. Before she enters, Papaya gets bored by the MomiGrub to retrieve the Orb. She then slaughters the MomiGrub with her lipstick.

Justice Weazels
While not confirmed, these small white-colored weasels seem to be Terexi's lusii since no other has been seen or mentioned. When Petpeta goes to Terexi's hive she eats one of the weazels and prototypes another. Petpeta leaves and Kobobo is left to watch the Weazelsprite fuse into Aradead.

Vrasky's Lusus
Presumably similar to her Lusus in Homestuck. Final Agent killed her lusus after introducing Vrasky to her role as an Omnidaddy

Arther
Arther is Equihorse's centaur butler of a lusus and gives him a supply of towels to clean his sweaty self. Equihorse has s*x with Arther until he dies leaving Equihorse towel-less

GlubGlub
GlubGlub is Fefieri's lusus. If we follow Homestuck, GlubGlub is most likely a HorrorTerror that was meant to wipe out the Troll race with the vast Glub. When Eridumb tries to get GlubGlub to be his daddy however, GlubGlub commits suicide without a Glub. The Trolls go extinct when Fefieri declares the law that all trolls must die.
