Union Academy is a school made for students who are born with powers that could be used for the greater good to save and protect the world. But some born with it misuse them for their selfish desires and twisted goals, that's why Union is created with teachers to teach the young minds how to use them with great responsibility..... Of course, despite the good meaning behind the school, bullying is still a thing and some teachers don't even bother to show compassion for some of their students. As evil is on the rise again and getting stronger, Ozpin and the Headmasters of Union are getting desperate to train more Heroes in order to counter the incoming threat to their peace and order. James Ironwood, one of the known Headmasters, has found an unknown anomaly that came from a different dimension that contains unlimited amount of energy and power. Seeing the opportunity, Ironwood wanted to begin experiments of new weapons and technology with the newly found power source, which made Ozpin worried about the anomaly's true origin. Unbeknownst to them, the so-called power source has a lifeform sleeping within, and it's about to awaken to bring either destruction and chaos to world, or peace and order.

(This story is a sequel, taking place after the Abyss Sans Story) "I-It is very amaz-azing how one can cha-change, by the most disastrous of decisions, and the most-ost dumbest of choices. You Uni-Union People thought that it would be fun-funny to try and agonize me, and try to kill-ill my brother, only for me to make you all pay for what you had tried from do, and me hav-having to take extreme decisions to make mea-e-e change, mak-king me who I am now through a long complex process. You all are even more of an abomination than the AUs that I have destroyed in the pas-past. And back than...my mind is as unstable as it always has been. But now...now...it is different. I am far more different than I used to be. Far more stronger than-an I used to be. You all...you all are nothing compared to me. You are nothing but puppets on strings-ings. Filthy glitches in the multi-multiverse. An awful mistake, a nasty bug...that I need to correct-ected. You people can lie all you like, claiming that you are heroes, and yet, you act so messed up and disgusting in the way that I can see and realize in it. I don't care what people think of me, nor-or do I car-care if I am hypocritical or not, if what I do is just-unjustifiable, as for all I care, it'd be really nice if you kept your mouth shut once for a while. And I, Error, the Destroyer of the AUs, will be the end of who you all are, and the end of what you will never be. Your power cannot the power...of my Anti-Void, and the power...of my master. I may hate creation and the Multiverse...but I a-am still willing to do what is right in the end, even if I hate it. And I will mak-make sure...your history will never be known again, and your legacy...of the future...will be era-ased." ...Error The pictures don't belong to me.

"I had thought...I had believed...I had hoped that...because you are heroes...you would care more about the lives of others, regardless of what and who they are, and that being heroes...you would care more about the people and the future that they like to make for themselves. But you Union Students...you Union People...you are nothing but traitors and hypocrites to those that looked up to you, who abandoned those that pleaded for you aid, and left them to die, boasting your fight to those that are as evil as you are, and flaunt of your superiority to those under you. I will not let you do this to them anymore. If you refuse to change your ways...and continue with this path of damnation...than I shall be the true hero. One that will lift everyone into my arms...and not the way you abandoned the powerless into the darkness to be forgotten...alone. I will be their hero, and you...will be the fallen. I will not sacrifice people to achieve my goals, and I will not discriminate those that are without powers or of another race, as like every other being...they deserve a life that they can choose to have. And nothing will stop me for fighting for the Discriminated, the Weak, the Powerless. Those that are beating down others for the showing of their own superiority, let me tell you something: you are not heroes...nor are you monsters...you are nothing more...than Megalomaniacs...worse than the very evils that you had sworn to protect the innocent from, that all of you had sworn to fight against. And more importantly with of all...I will accept who I truly am...and embrace my other side of my heritage, to finally be free." ...Sans Gaster The pictures in the story don't belong to me, except the AlphaAbyss Brothers.

20 parts Ongoing
Cover Art by MisterLloyd Headmaster Ozpin is in a bit of a pickle. It has come to his attention that one of his potential students has faked their transcripts, leaving him no choice but to reject their application last minute. However, that still leaves an empty slot needing to be filled, or else one unfortunate group will be a member shy of a team. But with Initiation in two days' time, where he is supposed to find a suitable replacement before then? Well, as it just so happens, there is someone who could take their place. He may not have an official application, but Beacon has made exceptions for that before. While he might have quite the temper, the school faculty is well-equipped for dealing with more volatile students before. What was that, he is an infamous terrorist and known murderer? Hey, everyone -even Adam Taurus- deserves a second chance, right? What is the worst that could happen? Now crossposted on Archive of Our Own.
