God Slayer

God Slayer is a 5-act story that primarily follows Vincent and Checkers.

Background
God Slayer leads directly into The Other Side. It is written by Techno Tinker.

Only A Lad
Vincent is studying in the Becile complex library in hopes to score higher on the Academy entrance exam. He is eventually visited by Checkers, then known as Kelin, and the two talk for a while before Vincent reveals research notes that he'd taken from Halcyon. Kelin expresses concern about Vincent having this information, but Vincent assures him that he has no plans to do anything malicious. He shows Kelin the existence of the multiverse and that they are from dimension Beta, then goes on to show him how dimension Theta has a crystal that can grant its user extraordinary power. Kelin is still skeptical, and eventually leaves Vincent to his research.

A few years later, after all of the Psi clones are fully mechanized, Vincent is alone in the dining hall, as the clones no longer need to eat traditional food and thus have cut mealtimes from their training schedules. Vincent is stuck in his mind, constantly wishing he were perfect, and eventually returns to his room, where he gets the idea to mechanize himself, drawing out exactly what he wants to look like.

Prototype
Vincent, after a shady deal with a currently unknown man, is set to be mechanized and turned into a cyborg after a long wait. When he wakes, the workers fully integrate his brain with his cybernetics, and a Becile worker named Warren helps teach him to walk and gives him clothing.

Meanwhile, Halcyon learns from Bone of Vinny's mechanization and orders him to keep a close eye on the clones.

Emperor's New Clothes
Checkers, after Vincent kills the clone Iota, goes and finds him, and the two have an argument about Vincent's mechanization and behavior. Vincent tries to convince Checkers to join him, but Checkers refuses, and soon Halcyon and the rest of the Psiblings banish Vincent into another dimension.

Dark Matter
Vincent, after being exiled to dimension Theta, takes up residence in an abandoned factory. A pair of police officers go to investigate reports people have sent in about him, and Vincent kills them.

Years later, remembering the research notes, Vincent finds the Theta crystal and brings it to its respective altar, granting himself the power it promised and thus fulfilling the prophecy mentioned earlier.

Universe On Fire
After detecting a shift in spacetime, Halcyon takes Bone and the rest of the Psiblings to dimension Theta to investigate.

Using his power, Vincent creates an army and destroys the Earthspace militia of that dimension, ambushing Halcyon and the Psiblings when they arrive. In a battle in the space above Earth, Vincent gives chase to Checkers as he breaks away from the rest of the group. Checkers then uses the black matter core in his ship to destroy the Earth and, by extension, the source of Vincent's power. In doing so, a tear in spacetime opens and starts the collapse of dimension Theta. Using his last scraps of power, Vincent escapes through the tear into the next dimension. Checkers chases after him. Halcyon and the Psiblings leave, and dimension Theta is no more.
