I had this idea and I just had to put it in words. It's pretty much Pacific Rim and RWBY but not an actual crossover. This story will be an AU of RWBY where the people of Remnant was not driven to near extinction but they still discovered Dust and developed advanced technology and such. The Faunus Rights Revolution still occurred, Faunus are still prejudiced, but the White Fang did not get a chance to go violent. Instead, Remnant is invaded by colossal creatures that the people have decided to call Grimm. The Schnee Dust Company proposes the Reaper Program, giant robots operated by pairs of Huntsmen/Huntresses to fight the large Grimm on equal ground. Also, to those who have read my first story Gunslinger World, I am sorry to say that I have run out of ideas for that story. Two years ago, I had what I guess is called writer's block and school and what not and blah blah blah. Anyways, I apologize to whoever was reading that story. I just can't think of how to follow it up :(. Maybe someone else would like to continue what I started, hehehe?

I do not own RWBY nor Pacific Rim.

Prologue

Monsters. Demons. Prowlers of the night. These creatures go by many names, but they are simply referred to as Grimm. It was a normal day when the first one arrived off the coast of Vale, and contrary to popular belief, it occurred while the sun was still up. The attack simply continued into the night, earning them their moniker as creatures of darkness. That and the fact that their hides are as black as night with eyes red as blood and that they come from a swirling mass of darkness located deep beneath the ocean. Vale City became a nightmare, a path of destruction trailing from the coastline all the way to the inner city. The armed forces tried their best to stop the creature as the air was filled with the scent of gunpowder and death, the sound of rifles and artillery combined with screams of terror, and that horrifying howl that reminded many of a wolf from hell. Its skull-like mask was a visage of death itself as it rampaged through the city.

By the time the first creature fell and began to dissipate, half the city lay in ruins. Six months later, Mistral was attacked. Months after that, Atlas. The people came to a grim realization that these monsters will keep coming, thus leading to the name Grimm. The leading powers of the world convened a meeting on how to deal with this threat to both humanity and Faunus alike. The head of the Schnee Dust Company proposed the Reaper Program after seeing his nine year old daughter watch a cartoon about giant robots. Wary of another imminent attack, everyone involved went straight to work pooling their resources together to create these mechanical monsters called Grimm Reapers or simply Reapers because they are the ones that will reap the Grimm. The pilots are given the title of Huntsmen or Huntresses because they are the only ones brave enough to hunt the Grimm down in way that would be considered too close and personal.

12 years later

Ruby Rose lay in bed dreaming of better times filled with cookies and strawberries. At 19 years of age, she is the youngest fully fledged Huntress to fight against the Grimm. She is also the youngest to be stationed at Signal, one of many bases around Remnant for Reaper deployment. So far, she has only encountered two Grimm of the Beowolf category, named so because of their wolflike appearance and howl. Being quite talented and considered a child prodigy during her training, she was able to slay the creatures with minor difficulty. Of course, all of this would not be possible without help from her partner, who she loved dearly. Her partner was also her mother, Summer Rose.

Summer was also an exceptional Huntress, although not as young as her daughter when she first started, she was very skilled that one can say it runs in the family. When Ruby was still in training, Summer's partner was a Huntsman named Qrow. Qrow and Summer were considered some of the best pilots and their compatibility with each other made others think that they were siblings, although neither has confirmed nor denied it. Even Ruby became close with Qrow to the point that she called him her uncle. It was by chance that Ruby and Summer became partners after Qrow suffered a training accident that required surgery. Mother and daughter were sparring together while trying to find a suitable replacement partner while Qrow recovered. Summer decided to run a simulation with Ruby and it was discovered that they were compatible with each other just as much as Qrow and Summer. Two days later, a Beowolf Grimm appeared near Vale and the mother and daughter team was deployed to take it out with great success. Several weeks later, another was taken down. All of Signal came to recognize and value their skill that even Qrow, who had recovered by that time, decided to let the Roses fight together while he would help with the trainees.

Back to the present, Ruby was currently enjoying her dreams of sweet confectionaries. As she was about to pick a delicious strawberry, a voice came from it saying, "Time to wake up, little rose."

"Huh, what the hell? Fruits don't talk," Ruby said while scratching her head. This time, a giant cookie landed on her forehead.

"Wake up," it said before jumping up and hitting her head again. This time, Ruby awoke from her dream with a yelp. Rubbing her head, she looked up to see her mother at the side of her bed, hand poised from lightly smacking her forehead.

"Mooooom, what was that for?" whined Ruby.

"Well, it's almost time for breakfast and we both know neither of us want to be late, especially with your appetite. Besides, what kind of example would you be setting to future Huntresses by sleeping in?" Summer responded.

"Ugh, you're supposed to be telling this to Yang," Ruby grumbled.

"Hmm, I would but she's stationed at Beacon, remember? So come on, get up. Move your sleepy butt and get ready for the day."

"Yeah, yeah, fine. I'm moving."

"Good girl," Summer said, lightly pinching and kissing Ruby's cheek before stepping out of the room. Ruby reached up to touch her cheek and smiled softly.

"What would I do without you?" she sighed.
