Foreword:

This story is a crossover between Godzilla and RWBY, in the sense that Godzilla is one giant Grimm among the rest of the Grimm on Remnant. The Godzilla being used in the story is the 2014 Legendary Pictures version of Godzilla. In this version of the RWBY timeline, the tournament is still going on strong, Penny was not destroyed, Valentine never faked a leg injury and ruined Yang's reputation, and Pyrrha is not dead. The tournament is still ongoing. In this version Cinder, Mercury, Emerald, etc. are not enemies, they're actual students from Haven, and are just big jerks to everyone. Salem is still a problem, but in a different sense. Everyone will be working together to be solving a suddenly much larger Grimm problem.

Now that you know what to generally expect, let's get on with it.

The Grimm Apocalypse

Chapter 1: It was just like any other day…

It was just like any other day in Vale. The city was busy with citizens going to and from work, kids playing in the streets, the usual. Everything was nice and tranquil, as it always is. The Vytal Festival was in full swing as well, bringing many tourists and exchange students from around Remnant all to Vale. The Tournament was in Singles at this point.

Team RWBY has shown themselves to be a very formidable force to the rest of the tournaments' participants, beating their opponents in the team, doubles, and singles fights. Team JNPR has also shown very tough, with Pyrrha Nikos defeating Penny Poledina (but not killing her) just minutes ago. Everyone in the stands, participants of the tournament and spectators, were all having a blast and enjoying the tournament. With the fight having just ended, many of the fighters and spectators left the stands to go relax at the concession stands and festival going on below the stadium.

Team RWBY and Team JNPR went to go hang out at their favorite noodle place (and Blake's favorite seafood place) to have some fun and celebrate both team's victories.

"Pyrrha, you were absolutely amazing out there!" Yang exclaimed sincerely, arms outstretched in amazement.

"Why, thank you Yang! You were not bad yourself!" Pyrrha said, returning the favor.

"Mmmhmm!" Nora mumbled, her mouth already full of noodles.

Ren facepalms at seeing Nora's terrible manners, but what else did he expect?

Ren then looks over to Blake, to see her face stuffed with fish, similar to Nora. Blake pauses, and returns an embarrassed stare to Ren. Everyone can't help but chuckle at this. At this, everyone then begins eating that hasn't already.

After a few minutes of eating, RWBY and JNPR sit back, deeply satisfied with their meals.

"Those noodles were better than last time!" Ruby exclaimed in satisfaction.

"You can say that again!" responded Jaune, equally satisfied.

Nora then belches loudly. Everyone can't help but to laugh at this.

The old chef then hands the bill to Ruby, who at the sight of the hefty price turns pale and limp.

Quickly, Weiss takes the bill away from Ruby, saying happily "Don't worry guys, I've got it covered for real this time." Handing her card to the chef to pay, she is delighted to see that it was accepted this time, avoiding another embarrassing situation due to her father cutting her funds.

Everyone turns to Weiss, and thank her gratuitously.

Yang chuckles and Weiss raises a questioning eyebrow at her. Trying not to burst out laughing, Yang tries to say as plainly as possible, "Thanks Ice Queen, it's great to see that your money is no longer frozen!" upon finishing her sentence, Yang bursts into laughter, hunching over the table and slamming her fist on the counter repetitively. Everyone else, except Weiss, also start laughing heavily, just not as much as Yang.

No one wished they could have anything different than they have it right now. They have all made amazing life-long friends, and they wouldn't trade their experiences for anything else. They all hoped their good times would continue for as long as everyone was around.

As teams RWBY and JNPR are finally calming down, Weiss still unamused at Yang's joke, they were all interrupted, feelings of fun, tranquility, and safety replaced with fear. Worry. Agony. Vale's emergency sirens have just turned on, and it was not a test.

Five minutes earlier…

General Ironwood stood in Ozpin's office, sipping coffee out of a mug next to his old friend, looking out at the stadium, and the festival below. Atlas was chosen to keep the festival safe this year by the Vytal Festival council, as is procedure every time the festival is held.

Ozpin then looks over to Ironwood and says matter-of-factly, "See? All of this extra force you brought, and nothing has happened, and the tournament is already almost over."

"Well, in today's day and age, you can't be too careful, now can you?" Ironwood responded, waving his hand out towards his prized airships hovering nearby over the docks.

"I suppose," Ozpin said, taking a sip of his coffee.

A few moments of silence pass, and Ironwood gets a transmission from one of his security officers that they are sending a squadron of fighters to scout a possible small group of Grimm outside the city so the South East of Beacon. As soon as Ironwood finishes reading the message, he looks up to see a small squadron of his prized fighter aircraft buzz the tower.

Ironwood responds to the sender cheekily, with 'did you tell the pilots the pattern is full?', and chuckled to himself, proud of his terrible joke. Ozpin rolled his eyes at the sight of Ironwood's return message when he shows it to him. Ironwood smirks, and then turns on his receiver to hear what the squadron has to report.

"Ghost squadron, General Ironwood. Report your findings once you've made visual contact, over."

"Roger that general, we'll be approaching the area momentarily." The squadrons' transmission was followed by the classic static sound that one would hear at the end of a military radio transmission.

"I love that sound." Ironwood said to Ozpin, who smirked in response.

Suddenly, Ironwood receives a video transmission. The Ghost Squadron leader exclaims, "uhh… General? You're gonna want to see this…" he says nervously, and turns the camera to look out front of his cockpit.

"What is it captain?" His question is immediately answered however, when footage of the biggest Grimm he's ever seen pops into view. Eyes gaping, and awestruck, Ironwood quickly show Ozpin the newest problem to hit Remnant, and it was heading for Vale. In the camera was a giant lizard-like creature, but unlike any Grimm they've ever seen before. At over 350 feet tall, it easily stood over the dense forest, and dwarfed the mountains behind it. It had a terrifying face that scared even Ozpin. With Blood Red eyes, and what looks to be hundreds of sharp teeth, and long, sharp, and jagged spines with the signature blood-red veins of a Grimm all over them, going from the back of its head, all the way down its back, getting larger the further down it went, then getting smaller again as it got closer to its enormously long tail, and continued down to the tip of the tail. By now the two men have run over to the other side of the tower to get a better look at the beast coming their way.

"Holy dust…." Ozpin said under his breath, terrified.

"Ghost squadron, engage immediately!" Ironwood quickly switches radio channels so he is heard on all military frequencies. "Attention all units, we have a massive Grimm to the south east of Beacon Academy heading straight for the festival. Halt all current missions immediately and move to engage as soon as possible! Turn on the emergency sirens and begin evacuating Vale. All airships move in to attack!"

At this, the emergency sirens can be heard, having just being switched on, and the three Atlesian airships Ironwood brought as part of the security force are seen moving in unison towards the creature.

"We need to get down from here and help with the evacuation." Ozpin says quickly. Ironwood nods in agreement.

Back with team RWBY and JNPR, they begin to leave the festival grounds, worried what is going on, but moving to a defensive position with the first Atlesian squad they come across.

"What's happening lieutenant?!" Yang exclaims at the soldier in charge of the security checkpoint. A Paladin mech can be seen moving behind him, deploying for a defensive position. AK-200 soldiers are being deployed in numbers as well.

With fighters screaming overhead in squadrons by the dozens and the three large airships on the security forces closely behind, the two teams can observe that they are all headed towards something in the forest. "We've confirmed a giant Grimm heading in this direction, an-" The Lieutenant is quickly cut off by a sudden and large amount of panic coming from his radio from all of the aircraft heading to the target. Teams RWBY and JNPR are easily able to hear this over the man's radio, even with the ships overhead, and the panicked screams of people around them, unsure of why the emergency sirens are on. They all look up over the forest in time to see quick flashes of blue light, accompanied by cracks in the air a couple seconds later. The pulses quickly grew more frequent, then it remained a large blue light remained in the one spot.

Then, for a moment, everything went silent. Over the radio a frantic transmission can be heard by one of the forward ground troops, "EVERYONE GET THE HELL DOWN!" Immediately afterwards, a thick blue streak emerges over the tree line, causing the sky to darken around the extremely bright beam of light. It sounded just like a rocket's engine, only constant, and very close by. The beam of mysterious light goes straight for the rightmost airship, then sweeps leftward, cutting all three ships in half horizontally, forcing them to explode violently, killing everyone inside instantly, and with it, their greatest chance to destroy the beast, all in mere seconds.

All citizens unfortunate enough to catch the event begin to scream in absolute terror. The screams suddenly stop when a deafening roar is heard, presumably from the same creature that just destroyed their greatest symbol of safety. By now, the entire kingdom knows that there is something greatly wrong.

Screams resuming, louder and stronger than before, Yang yells over the screams with an extremely concerned look on her face "What the hell was that?!" Inside, Yang did not want her question answered.

The monster had other plans however, and as Yang finished her sentence, the biggest Grimm ever pokes his head over the tree line, getting higher in the sky every thunderous step he takes towards Beacon Academy. Yang's question was answered, and she, as well as everyone around her, were scared to death for the first time in their lives, seeing their impending doom coming straight for them. Godzilla then lets out another deafening roar, followed by hundreds, if not thousands, of smaller, more typical Grimm, coming out of the forest, headed straight for Vale.

Sounds of gunfire and rockets fills the air as the Atlesian military tries to hold back the onslaught.

"Holy… dust…." Yang says under her breath, absolutely awestruck at the creature, now visible from its waist up. Everyone looks at it in fear. The King of Monsters has arrived in Vale.

(A/N), 7/26: Hey Guys! I had no idea how many people would be viewing this, and i gotta say, I am absolutely ecstatic! Last time I checked, the story broke 155 views! I know that not necessarily everyone who viewed it liked it, but that's a huge start for me, especially for my second fanfiction! Anyways, I'd like to announce that I will definitely be continuing the story for many chapters to come. A general plan has been formed, and i can confirm that there will be more Kaiju from the Godzilla universe, and one (technically two) from outside. There will be a total of 29 as of this moment. You'll have to stick around to see which ones. Additionally, I plan on releasing Chapter 2: Pain and Suffering before or on Friday, July 29th. I hope you guys will like it just as much as i do writing it.

Thanks again everyone!
