Ok, building of Intermission's idea of them being part literally every race in Homestuck:

They are a sprite^3, made of two double prototyped sprites, both prototyped into one kernalsprite. One of the halfs is a half fuchsia blooded troll, half human ectobaby who's a Dirk-type antihero and planned this whole thing. She is the Lord of Mind and prototyped her first-guardian lusus before god tiering and self-prototyping.

The other half is a cherub who didn't predominate, but instead merged their two halves to become the RougeThief of Spacetime. Their kernalsprite are made up of themself and their secession's WV.

The unprototyped sprite came from an alternate timeline cause it's a two player secession.

The sprite^3 DOES have both queen's, but they literally do nothing because they ARE all of that secession's prototypings in one.
