The following is a fan-based crossover. Red vs Blue and RWBY are the product of RoosterTeeth. Please support the official releases.

The time setting for both series being crossed over is as follows:

Red vs Blue: Immediately after Volume 12

RWBY: Immediately after Volume 2

And yes, I have watched both to the end.

DO NOT read this fanfic if you haven't seen Red vs Blue Volumes 1 thru 6. Everything after Volume 6 is based on a MAJOR spoiler that will completely change how you saw Volumes 1 thru 5. I won't go into the details, for obvious reasons.

There might also be some minor spoilers that might ruin Volumes 7 thru 10 for you if you haven't seen them yet. If you're done with Volume 10, I expect you should be safe from spoilers for Volumes 11 and 12. There will, however, be some unanswered questions, given that it takes place after that. I also included a small tidbit that I picked up from Volume 13, even though this fanfic's setting was inserted before that.

As for RWBY, this fanfic contains what might be considered a spoiler for Volume 1. However, many viewers have reportedly found it to be an obvious guess before it was actually revealed.

And yes, there are some vague references to RWBY Volume 2, which you're about to see very soon. Hopefully you can handle a heads up THAT Roman Torchwick was finally arrested and still enjoy watching the actual series to find out HOW he was arrested.

"Remind me why we're spending our down time in Grimm territory?" asked Weiss as she and the rest of Team RWBY wandered through the forest of Forever Fall.

"Because sitting around in the library is sooo boring," said Yang.

"Because there's still too much evil in the world to ignore," added Blake.

"You realize that Torchwick is behind bars, right?" said Ruby.

"Trust me," said Blake. "There's plenty more where he came from."

"Right," said Weiss. "You're worried about cunning criminals like Torchwick, and somehow picking off barbaric creatures of Grimm is going to solve this."

"We're here to practice," said Ruby. "It will make us stronger. And it will be fun!"

"Fun doesn't win the war," said Blake.

"Geez, and I thought Weiss could ruin any moment!" said Yang.

"Come on guys, we're here to fight Grimm," said Ruby. "Stop arguing. What's the worst thing that could happen?"

"TODAY IS A GOOD DAY TO DEFY PROBABILITY BY NOT DYING!" screamed a hyperactive southern accent from above.

The four teenage huntresses in training looked up at the Nevermore that was plummeting in their general direction. It wasn't skydiving so much as belly-flopping. Team RWBY dove for cover, not having time to wonder why a giant bird would belly-flop.

When the huntresses looked up, they saw the Nevermore sprawled on the ground. Its dead body was slowly evaporating. Lodged into its back was a UNSC Pelican spacecraft. A team of troopers wearing space armor of various colors climbed out.

"See? I knew we could pull it off!" said the Red Colonel, who spoke in the southern accent from earlier and still called himself Sarge. "We just needed to find another flying object to break our fall and slow our descent."

"Something's broken?!" exclaimed Caboose. "Quick! Somebody fix it!"

"Maybe he was talking to some kind of audience," said Donut.

"That would be breaking the fourth wall, you idiot," Lopez, in his usual obligatory robot Spanish that nobody else understood.

"Good point, Lopez," said Sarge. "This planet definitely isn't Chorus."

"If I had said a planet's name, it would have sounded the same as in English!" said Lopez.

"What do you mean, why did we leave Chorus in the first place?" said Donut. "Locus threw a teleportation grenade at us, and we wound up on a spaceship filled with pirates!"

"Good thing I had picked up that energy shield to deflect his regular explosives," said Agent Carolina.

"Grif!" said Sarge. "Where's Simmons?"

"Oh, he's lazing about in the wrecked Pelican," said Grif.

"I'm not lazy, you hypocrite!" said Simmons from inside the Pelican. "I'm just afraid of the teenage girls!"

"Excuse me?" said Weiss angrily.

"As far as sexual bias goes," said Yang, "being afraid of us isn't all that demeaning,"

"It is for Simmons," said Tucker. "Especially when he was supposed to be the captain of an all-female army."

"Yeah," said Grif, "That was even more pathetic than the old days, when all he did was kiss Sarge's..."

"Ah-bah-bah-bah-bah!" interrupted Weiss in an attempt to silence Grif. "Language!"

"What are you, eight years old?" asked Agent Washington.

"This whole planet is infected by creatures of Grimm," said Blake. "Their entire purpose in life is to destroy humanity."

"Which makes it very ironic that a Nevermore - or giant bird of Grimm - saved your life," added Weiss.

"What does that have to do with language?" asked Carolina.

"The Grimm tend to hone in on negative emotional atmospheres," said Yang.

"So if you say dirty words," said Ruby, "you might as well scream, 'Come and get me, Grimm!'"

"Fascinating!" said Doctor Emily Gray, eccentric as always. "I have a lot of scientific observation to catch up on!"

"In all my life, I've never heard such bull..." started Grif, before Weiss shot a blast of dust from her Myrtenaster sword, encasing Grif's helmet in ice.

"Hrr!" said Grif in a muffled scream. "Whrt der frrg?"

"Um, I can't understand what he's saying," said Ruby, "but if he's swearing, won't the Grimm still hone in on his aura?"

"Does that answer your question?" said Yang, looking at a pack of Beowolves running towards them.

"For the time being, I'm trying to make it less contagious," explained Weiss.

"Murder frrgers!" said Grif, who had just walked straight into a tree. "GIRT DIRS SHRRT ERFA MER!"

Team RWBY surrounded the Reds and Blues. As the creatures of Grimm closed in, the four huntresses fought them off, keeping the troopers covered.

Tucker instinctively activated his energy sword in case a Grimm got through the outer defenses. Unfortunately, Grif bumped into him blindly. As Tucker stumbled to keep his balance, his energy sword slashed through the ice around Grif's head, melting it.

"It's official," said Grif. "I KEEGAKERGERK-ing hate every single one of you!"

"Church, is that you?" asked Tucker.

"No, you idiot! I'm Grif! Why would you think I'm Church?"

"You just made the noise that most people make when Church possesses them," said Tucker. "Although, he doesn't have to be in control. He could be probing for KEEGAKERGERK! Okay, Church, this is getting pretty disturbing."

"I seem to remember Church being somewhat of a misanthrope," said Simmons, "meaning that he hates every-KEEGAKERGERK!"

Meanwhile, Team RWBY was fighting off the last of the nearby Grimm.

"I think that's the last of them in this vicinity," said Blake.

"We should get the foreigners to a safe place as quickly as possible," said Weiss.

"Okay, I'm done," said Church, who was now hovering next to Carolina's head in miniature hologram form.

"Who's that?" asked Ruby.

"This is Agent Carolina!" said Caboose.

"I don't think she was talking about me," said Carolina.

"Who's the small transparent guy?" said Ruby.

"Oh, this is the ghost of her father! Church Carolina!" said Caboose. "He's also my best friend!"

"Yeah, for future reference," said Tucker, "don't listen to anything Caboose says. He doesn't know what he's talking about."

"Yeah," said Simmons. "I think he just set a new record for the most demented assessment of all time."

"That's not entirely true," said Agent Carolina. "I don't remember telling anyone that my father was the Director of Project Freelancer."

"Oh, yeah!" said Caboose. "I forgot all about that! My best friend is in charge of Freelancer City!"

"Yeah, he's pretty BLEEPed up," said Grif. "Wait, what the BLEEP was...what the BLEEP..."

"That was me," said Church. "I installed a profanity filter into everyone's helmet speakers. Also, when I was in Caboose's head, I may have caused a memory leak. I swear, it's like a haunted wasteland in there."

"Why bother with Caboose?" asked Tucker. "When was the last time he ever said BLEEP?"

"Oh, I say that all the time," said Caboose. "I like to press buttons, and I sometimes mimic the sound that they make."

"Excuse me," said Weiss, "but time is of the essence."

"Yeah," said Ruby. "We have to get you to a safe place."

"I thought you said that the whole planet was infected by these creatures," said Agent Washington.

"Trust me," said Blake. "You're more likely to avoid them in a city than in the wild."
