Hello! And welcome to a cool RWBY au I'm making! This au is basically a "semblance-swap" AU. Where different characters swap semblances. The swapping is pretty random; I simply based it on either character relationship, or characters who had similar semblances. As a general rule for the swapping, I decided that no student will swap with another student. Everyone has either swapped with an adult, or a villain, or in some people's cases, both.

As for the main characters, their swapping looks a bit like this;

Ruby switched with Qrow, and her semblance is now bad luck

Weiss switched with Mercury's dad, and her semblance is the ability to "turn off" or "take away" the semblances of others

Blake switched with Raven, and her semblance is now the ability to open portals to people she makes a "bond" with

And finally Yang switched with Hazel, and she is impervious to pain.

Everyone else's swap will be revealed with time.

As you can imagine, the plot will fall far away from cannon considering all the changes. I'm going to let the story develop as it goes, and see what happens. As for parings, the only thing I can guarantee at this point is Arkos and Renora. All the other relationships that will be cannon in this story are going to depend on how it develops. Whatever makes best sense plot wise/writing wise. So if I spend a few volumes building a relationship, either accidentally or on purpose, it's probably gonna go cannon in story. That being said, please don't complain if your ship doesn't sail. I don't really wanna hear about it.

Now, I will have spelling and grammar mistakes in this. I have a few learning disabilities, and am also only eighteen, so I will not be a perfect writer. Feel free to call me out on my grammar mistakes, but don't judge the quality of the story on the quality of the grammar.

Also, leave a review, but no flames. If you want to leave constructive criticism, go ahead, but actually give me some advice I can work with. I've gotten flame reviews in the past, and the most annoying thing about them is that they only spew hate, instead of giving me actual advice on how to improve.

And finally, a disclaimer: I don't own RWBY. That belongs to RoosterTeeth animation studios, and I'm fine with that. This was just a small idea I had and decided to run with it. I hope you enjoy. Please leave a review!

And without further ado, on with the show!

Red

It was only October, but the winter snow had flooded in early that year. This wasn't a bother to the little girl in the red cloak. The warm hood protected her face from the harsh winds, and her black fighting boots kept the cold snow from bothering her small feet. Her black dress, which folded into a childishly pouffy combat skirt was made of a special fabric that could easily insulate, regulate, or release heat, depending on the wether, keeping the little girl warm in the winter, and cool in the summer.

This little girl was Ruby Rose. She was pale, though during the warmer months she could gain a pretty summer tan. Her hair was short, and black, with the tips of her hair a brilliant dark red. Her most notable feature, however, where her stunning silver eyes.

She stood by a tombstone. This was the resting place of her deceased mother, Summer Rose. The grave read, "thus kindly I scatter,"

The white snowflakes fluttered carefree, letting the wind carry them to their destination. If little Ruby imagined hard enough, she could see the white bundles of fabric that where her mothers cloak; her spirit dancing in the snow.

With her brief visit over, the little girl began to wonder through the forest, back to her home.

She walked, humming an old lullaby to herself, sung to her by her mother before she passed away. The wind lightly kissed her face. It was beautiful thing to simply walk home, during a snowy October day.

She came across a clearing, not far from her house. Several wolflike creatures had conjugated at that spot. Their bodies where pitch black, like black holes in deep space. The only color that shown through where their glowing red eyes, and the white, bone-like plates on their heads like mask. These where the creatures of Grimm; hostile monstrosities that fead on negative emotions, and human flesh.

Ruby let out a small sigh, seeming slightly annoyed. She didn't feel like fighting today, but she would do so, nonetheless. "Just my luck," She hummed, her hands moving to the familiar collection of red, black, and silver metal that she kept hidden under her cloak for whenever she found herself in a fight.

Seeing a human that they always craved, the wolflike monsters began to circle in on the little girl.

But she was not afraid.

The first wolf made it's move.

Little Ruby whipped out her contraption; whose handle popped out, though the rest was still folded in. This was her weapon on gun mode.

Loading the weapon with bullets, Ruby took a few shots at the wolf charging at her. The bullets angrily boor themselves into the monsters skin, slowing it down, though not stopping it completely. Sensing the hostility, the other wolves began to charge in as well.

The little girl couldn't help but smile.

She jumped into the air, her hood falling off her face as she completely unfolded her weapon, revealing it to be a giant mechanical scythe. She soared around, her selhouohette reflected by the broken moon. She landed with grace, snow crunching underneath her feet, as she swung her weapon around herself, slicing one of the monsters in half. It started to disintegrate into shadows the moment it died.

Then it was onto the next one. Ruby leaped over one of the incoming wolves, letting it trip over its companion. She smirked. Being unlucky had it's advantages sometimes. The little girl swirled around, letting her scythe cut into the enemies, taking them down. She spun her weapon, smashing it into the ground, and letting shot after shot fly into the monsters skins.

Lifting her scythe out of the ground, she jumped into combat with the next one, swirling her weapon in the most intimate dance known to man; battle. She thrust her deadly contraption forwards, and pulled it back, before letting out a gunshot, using it to propel her weapon forwards, and straight into her opponents scull.

She pulled her scythe around, letting out gunshots at the next wolfs chest, then slicing her weapon upwards, stabbing through a different monster, who had tried to attack her from behind, and letting both its body and the sharp edge of her weapons blade land in the snow. She lifted the scythe out as it's body disappeared, stepping back, with one foot, then the other. She jumped up, Pointing the staff-like handle downwards, while the blade faced up. She shot a bullet, giving her some extra momentum as she quickly spun the scythe around her little body, clockwise, and hammering it into her target.

The three remaining Grimm eyed her cautiously, while the body of their fallen comrades disintegrated, leaving no trace of their presence, as if they had never been in this clearing at this time in the first place.

The wind started to pick up, blowing the snow around in harsh whips of cold. This action created a slight bit of a fog, making it difficult for little Ruby to see the remaining monsters. However, they where just as blind as she was, and the harsh winds would keep them from tracking her with their sense of smell.

Ruby stood absolutely still, focusing on the sounds around her. The wind whipped, though it didn't howl, allowing her pale ears to pick up on even the slightest of sounds. The crunch of heavy feet in the snow, the low, rumbling growls of the wolves, and the rustle of their fur as they moved. The sudden increase of wind was unfortunate, but not unexpected for the little girl. After all, she carried bad luck wherever she went.

One wolf rushed towards her, but she twisted her body so that it ran straight into the sharp end of her weapon's staff. The second wolf was a lot more cautious, circling around her carefully instead of jumping in. But it was moving to slow, and all Ruby needed to do was lightly jog towards it, before slicing it down the middle.

The harsh wind stopped, and the snow cleared up, letting the little girl in the red cloak and the wolflike monster to see each other eye to eye. They both ran at each other at the same time, but the wolf slid out on the freshly fallen snow, allowing Ruby to kill it.

The little girl steadied herself, leaning against the scythe, as she caught her breath. Shells from the bullets she had shot that had been swept up in the snowstorm finally fell to the ground, landing at her feet, staining the white crystal-ground gray with rust and gunpowder.

And that's it for the red trailer. As you can see, Ruby's semblance is different. And as the semblance itself is described by Qrow in cannon to be both a help and a hindrance during battle, I did my best to describe it that way. Hence the spontaneous snow storm.

Now, Ruby's version of Bad Luck will be somewhat different than Qrow's, mostly due to their difference in upbringing. She can't turn it off, and it's a little out of her control, but she is going to be able to manage her semblance better than Qrow can, since she was guided by loving mentors who did their best to keep her from thinking she is a curse, while Qrow was raised by bandits who probably loved to rub his "curse" in his face. And knowing Raven, I can safely assume she probably bullied him for it in her youth.

Now, leave a review, if you are interested in this story. If I get at least one review per trailer, I'll make this into an ongoing series. And I would also appriciate it if you checked out my other works. I write a lot of Fullmetal Alchemist stories, and am working on an AU in that section now that any FMA fan would enjoy. And if you wanna see my contribution to the Ruby fandom, check out my previous fic, The Boy with Blood Red Hair, a two-shot about Blake, as she tells the story of how her relationship with Adam turned from close friendship to horrible abuse, and her journey into recovery.

I guess that's all. I hope you enjoyed!
