Hello! I was inspired by the challenge from Crossoverpairinglover, so I decided to write this fanfic. Let's see if I can focus long enough to finish it.

I do not own any of these franchises.

FusionFall Multiverse

Prolouge: Vision of a Coming Storm

Have you ever heard of the Multiverse theory? Where there is a hypothetical set of infinite and finite universes, dimensions, parallels strung together in the great web of fate and karma, including ours? These universes present an infinite number of choices one could take; for better or worse, no one if I didn't eat this sandwich? What if I won this race? What if I sacrificed myself to save my friend from a gruesome death? Few believe such a tale, fewer try to pursue it. Those that do are either written off as crazy, or gain little helpers to achieve such an impossible goal: to access and move around the so called multiverse. Either way, they all fail miserably.

Of course, they don't live in a world where wizards go to school, animals talk, ninjas have demons trapped inside them, children possess robotic suits, and super powered people prowl the world for both good and evil.

My name is Luna Lovegood, 14, student at Hogwarts School of Witchcraft and Wizardry. I am also a seer. Yes, like what that fraud Trelawney claims to be, but unfortunately for her, she got the shorter end of the stick when it came to access to her powers. She could only glimpse things, and doesn't even remember what she saw afterwards. I, on the other hand, can see visions longer, more clearly, and can occasionally do it by sheer willpower, but that's a lot more tiring. They usually come at night, in my dreams. They've been more confusing and annoying in the recent days though. Glimpses of green, flames, stars snuffed out, cries, screams-

"Ouch!" A dish crashes to the ground, shattering into many little ceramic pieces. I hiss in pain; some of the shards hit my ankle and caused a nasty red gash to appear. I make sure to steady the other dozen plates I'm holding, and place them on the table.

"Sweetie, are you okay?" My father calls from downstairs, his voice full of worry. I smile. I love my father, I really do. Even after mother died, he made sure he was actively present in my life. He always made sure I was happy and content, even allowing me to make up those funny articles in the Quibbler. Poking at the Ministry with made-up charges is always fun, and is a good stress reliever in my opinion. My parents always said I was creative. My mother said being creative is good for a budding seer. It helps the seer be more cryptic and confusing to desperate idiots. Anyway, I'm rambling a bit.

"I'm fine Dad, thanks!" I shout, smiling. I wave my wand, muttering "Reparo", and place the now repaired plate on the table with the others. Then I tend to that annoying gash on my ankle, leaking a little blood. Oh, you might be wondering why I was carrying those plates when I have magic. Well, daddy always said that it won't hurt for you to do things the muggle way, so you can understand how they cope without magic. And so I was enlightened. I am SO getting a car when I turn eighteen!

I finish cleaning and healing my wound (the muggle way! Besides, I don't know healing magic), and look outside the window. It's a beautiful day outside. The birds are singing; flowers are blooming.

Somewhere in the world, a very punny skeleton sneezes all over a plate of spaghetti, much to the dismay of his brother.

On days like these, it's perfect for a game of catch, or picking flowers. In fact, I think I do just that. I run outside, laughing and breathing in the fresh air. I love my dad, and my home. Here…..I can just be free. I look up to the sky, and spot six humans in the air. Except, they had wings on their backs, and one of them seemed to be carrying a dog. I laugh and wave, and see one of them wave back. Now, I know what you readers might be thinking…..

'But Luna, there aren't any angels in the Harry Potter universe, are there?"

To answer your question, no, there are not. Though by now, I'm not so sure. Those winged-humans were the Flock, a group of teens who were experimented on by birth. What are they doing in my universe? Well, let me tell you a story, dear readers.

In another universe, a boy genius named Dexter was deciding on what invention he should create next, preferably something without a big red shiny button. So after countless hours of thinking, he came up with the brilliant idea of messing with time and space. Now, normally this would be fine since he got all the schematics and kinks right. However, karma sucks, and his track record of working inventions is full of smoke and ashes, despite the inventions actually working to some degree. And it just so happened that countless other people around the Multiverse were performing similar experiments with space and time, including one Albus Dumbledore. To make a long story short, Dexter's invention worked. It also caused a chain reaction with other experiments across the Multiverse, and started ripping holes in the time-space continuum. As a result, many universes, or at least parts of them, were pulled together and merged.

I know. Crazy right?

And so, when each inhabitant discovered what happened, they turned to their respective heroes and protectors for guidance. And said heroes and protectors, when meeting their other-dimensional counterparts, decided to immediately work together to restore the balance and spread sunshine and rainbows…..NOT! Hehehehehe, you think a bunch of paranoid heroes and neutrals, dealing with their own problems from different ends of the Multiverse, could work together just like that?! No, most of them distrusted each other almost immediately, with their varying morals and ideas. The few open-minded ones were lucky to befriend those from dimensions not of their own, but like I said, few. And let's not even go into the problem the villains posed when they started banding together.

With the amount of tension in the sir, it was no surprise that war broke out.

The air was filled with smoke and screams. The ground was charred and torn asunder. Several bodies lay on the ground, some bloody, most broken. It was hard to tell if they were dead or unconscious. Two figures fought in the air above the ruined battleground, one in red and blue, the other in orange with spiky glowing yellow hair. They traded blows with such ferocity; onlookers would only see two colored blurs. On the ground, a pale muscled man, with tattoos red as blood, clashed swords with an orange haired man dressed in a black robe. Nearby, a skirt wearing figure seemed to dance out of the way, as glowing white spears embedded where she once stood. She pulled her own spear out of a gem attached to her head, and charged. The thrower, an eye patch wearing fish dressed in armor, growled and stood determined, ready to take her on. An old man, wrapped in gray, held his staff high and began chanting. His opponent, an old man dressed in blue and with a beard that would put Dumbledore to shame, flew up high to avoid the spell and began casting ice bolts at the grey wizard. One thing all combatants held in common: They would protect their homes at any cost.

The war lasted for 5 years, but it felt like ages to those who participated. And to top it all off, the rips never closed or lessened in number. As the war progressed, more and more parts of the Multiverse appeared, some coming by individuals, others coming by cities or even countries. One way or another, they all chose sides.

Then the war stopped, as quickly as it started. The five factions: The Federation of Virtua-Gama , Animania , Toonopolis, Lituratopia, and the Republic of Comivale signed a peace treaty and established their terms and boundaries. The person who headed this, the one who stopped the war, was a human child. Shocking isn't it? A mere child, not even a first year, did what experienced diplomats and peace activists couldn't. However, according to those who witnessed what happened, the sheer determination and mercy that was rolling of this child….it was indescribable. Heh, he sounds like a good kid.

Anyway, that was three years ago. We've managed to move on by now (surprisingly quick right?), though the war is still lingers on everyone's minds. But hey, the faction-states had begun opening up to each other a year ago. I mean, while they aren't exactly allowing tourists, they've opened up to trading so I guess that counts for something right? The only problem is that no one has managed to figure out how to stop the sudden portals appearing and depositing a new dimension. It's become something of a silent competition to take in as many inhabitants of each new dimension into one's faction as possible, depending on where the next portal appears. Heck, even the muggle news keeps tabs on it. So yeah, that's basically what's been happening around this mashed-up world.

I lay on the grass, taking in the bright blue sky and the fluffy white clouds. In just a month, I'll have to go back to Hogwarts. Back to walls, confining spaces, drama, prejudice, bullies…

'Enough depressing thoughts Luna. You have Ginny and Neville to talk to; it's not like you don't have friends. Of course, all Ginny talks about is Harry Potter these days, and Neville is…" I lose myself in my thoughts.

Dusk soon approached. I yawned and made my way back to my house. It's almost time for pie!

"Dad, I'm ho-"I'm cut of mid-sentence by a blinding, searing pain in my head. I yell in pain, losing my balance and falling to the ground. My father runs to me in worry, shouting something, but I can hardly pay attention.

A giant green monstrosity smiled cruelly as his forces clashed with the defenders. His form seemed to radiate evil. "Soon…"

A more battle-worn me ducked green bolts of death from….a green slime version of me? Only, my evil twin had red eyes and carried a wand, while I held a staff. I fired a bolt of lightning as my twin sent more Avada Kedavras.

A boy I recognized as Dexter typed furiously, several screens showing a loading bar. I saw myself and a few others I didn't recognize watching.

A small child-like goat monster joined hands with a human child wearing a purple and blue striped shirt. Both bodies' glowed, their white forms merging. When the glow died down, an adult version of the goat monster stood at ready, multi-colored fire forming in his hands.

Many heroes and villains gathered on top of a cliff, looking down to see what could be called an army of teens, fully equipped with an. Everyone stares overhead at the giant green planet in the sky.

Bloody, bruised, determined. The defenders of this planet glared at the green overlord. They would never give up.

Many more visions flash through my mind. It's too much…..

I shuddered as the visions ended. My head was still wringing with pain. I felt completely exhausted. My father quickly helped me up and had me sit on a chair. He handed me some butterbeer as he checked for any lingering injuries.

"My daughter, are you okay?" He asked, concern evident in his eyes.

"I'm fine dad. My seer abilities just decided to act up" I muttered, gripping the mug of butterbeer as my mind whirled with this new information. Who were those people I was with? Who was that giant green slime monster? Why was there an evil slime twin of me? What did this mean for the planet? The more I thought about it, the more conclusions came up. None of them were pretty. I realize that I saw that green alien (There is no other explanation) before. In my previous visions...he was standing over a dying world. I gulp and shudder once more. This…this is…oh no…

"Luna? Are you okay? What…what did you see?" Xenophilius Lovegood, my loving father, who has always cared for me when my mother passed away…..I saw what I was part of in those visions. If I tell him, he might try to follow…..he might get hurt….he…he might….

"…Nothing father. Nothing you should be concerned about. Just a bunch of nargles trying to take over the earth. I also have a headache" I finally say, closing my eyes and taking a sip from my drink. Thankfully, my father doesn't pry and heads off to get some headache-removing potions. I let out the breath I didn't know I was holding. My visions have never been wrong before. Judging by the frequency and intensity of these visions; whatever is going to happen will happen soon.

I can only hope the world is ready for the coming storm.

See if you can guess any of the characters hinted~
