In the lab near her house, Rose finds and names Mutie, which an imperfect cloning machine created from the paradox ghost imprint of Jaspers. Since failed paradox clones have strange mutations, Mutie has extra eyes. Only a perfect paradox clone can become itself; in fact, such a clone is guaranteed to do so.
When John attempts to appearify the ghost slime of Nanna, Grandpa, Bro and Mom from the 1st, 3rd, and 4th of December 1995 and the 13th of April 1996, respectively, their ghost imprints are created and sucked into four cylinders on a perfect-cloning machine. The imprints are analyzed for their DNA code, which is used to make the four as babies. The imprints are then combined and redivided into John and Jade (siblings) and Rose and Dave (siblings). This is part of a sequence prepared by Dad, Grandpa, Mom, and Bro themselves (although this detail was unseen). John executes the sequence creating, in total, eight babies.
Karkat with one half of his session's paradox clones.
Via the same process, Karkatcreated twenty-four wigglers. Because of this, it is presumed that the session leaders are usually responsible for creating the Paradox Clones. Certain elements of how he did so are not known yet, such as which supposed other two trolls created their genetic offspring alongside each one's dancestor, or which generations were perfectly cloned or bred from biological parents.
Successful paradox clones of players and potential players are taken to their planets on meteors during the Reckoning, where they crash land at various locations and times (which are considered their birthdays).
This offers one possible explanation for the players' and their guardians' powers; being cloned from themselves, any abilities could essentially come out of nowhere.
Hussie made some kind of error: All of the babies' legs, as well as one of Rose's and one of Roxy's eyes, are grey as opposed to black.
It is unknown if the ectobiology process for the trolls would actually create "siblings" among the genetically-combined players or if it would tamper with their mating processes, as it already concerns them taking part in an "incestuous slurry".
