Across the universe there are worlds that possess powers, some are hidden, others rely on them, some are use in machines and others are use for fun. However they all share common interests by protecting, defending and fighting off anything wether it would be monsters or villains in all shapes and sizes. The problem was that they all are on separate worlds, no way of traveling to these worlds or even know if they're truly are other living beings. Luckily there is an answer for that, what if there is a school where they are united. Let's travel with these alternate worlds where they all unite together and share their experiences together in a newly built school

Hero Time (Composite Ben 10 reader x Multiple Crossovers)
"In a world where Grimm, Danger Beasts, Monsters, and notorious villains run rampant, there are those who stand against them. Benders, Huntsmen, Heroes, people who have the power to fight them, for the sole purpose of defending the innocent. At least some of them. Other guys just want to prove how powerful they are, and push around people without powers. I learned that the hard way. My name is Y/n Tennyson. I'm 20 years old, and I am in possession of the most powerful alien weapons, in the universe. When I was little, people like Bakugo and Issei picked on me everyday, just because I was too powerless to do anything. So one day, I decided to drop out of Union Academy and went on a cross country road trip with my grandpa and cousin. Then on our first stop, I went out on a walk where a meteor fell out of the sky and crashed right in front of me. But, as it turns out, it wasn't a meteor, but a pod containing a watch that, once stuck upon your wrist, could turn you into any alien you want. Needless to say that my life went uphill from there. I traveled across the galaxy, saved it from blowing up. Fought a giant alien, AS a giant alien. Stopped a race from destroying the universe. Blew up my watch. Got a new one. Dated a tennis player, and broke up with her. Fought a giant alien, as a giant alien AGAIN, this time in Tokyo. Killed an interdimensional demon along with my archnemesis. And made friends with a Slimebiote named Skurd. Now me and my friends are unlicensed heroes who defend the world from destruction. Mainly because it's the right thing to do, but partially to show Union Academy what kind of hero I am now. And I can't wait to see the look on their faces."

The Evolving Hero and the Ruler of the Abyss (Union Academy x Abyss Sans)
"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.Complete

Kamen Rider Chimera
Long before Alpha City lit the night with neon and newsfeeds, the world changed in a single generation. Historians call it the Merge-a sudden convergence of dimensions that pulled entire lands and peoples from distant realities onto one enlarged Earth. In a matter of months, Remnant rose between Japan and Hawaii; Amestris surfaced in the Atlantic; and echoes of countless other realms-heroes, mystics, even gods-took root in the soil. Nations rebuilt borders overnight. Heroes from every world formed a new covenant to keep order and share knowledge. At the heart of it stood Union Academy, a sprawling citadel in Alpha City where young defenders of every race and power trained side by side. To many, it was proof that coexistence could work. But for the Revenants, the promise of unity never truly reached their doors. Older than any single world, Revenants were beings born from the deepest tempests and forgotten legends-half myth, half flesh. In ancient times they had defended wild frontiers and remote villages. Yet as humanity's fear hardened into policy, the Revenants were hunted, branded, and driven into exile. To most people, "Revenant" still meant monster. Even after the Merge, the old hatred persisted. News feeds blamed them for unexplained attacks. Cities posted hidden bans. Hunters roamed in silence. And every act of violence, no matter how isolated, became proof that the entire race was dangerous. But now, a new Hero has arrived to restore the balance and protect the innocent...both Revenant and Human. He is Kamen Rider Chimera, the Hero of Monsters (I DO NOT OWN ANY OF THE SERIES IN THIS BOOK!

The world was full of heroes and villains. both belong to different sides, from different factions. From light and darkness, they exist. They who walk the path of good where there is peace, hope, love, freedom, fun, joy, justice, and life. And they who walked the path of evil where there is war, despair, hate, pain, vengeance, sined, and death. All in opposite sides in one coin, there all the same. Through centuries as we remembered heroes always win in every story foretold. Defeating the dark forces which were the villains always falls. But to think that this day for the first time, the villains finally have the upper hand. When their king has finally been born... This is the story of a boy, not a hero but a villain. But not just a "villain", he's the King of Villains. To think that the once weak and powerless boy could lead the villains to victory. A evil king created by the negatives of the once called heroes " A villain is just a victim whose story hasn't been told " - Chris Colfer Author's Note: My male reader x crossover fanfiction story, enjoyComplete
