Hello everyone! I'm back with a brand new chapter and this time, I've decided to include an intro for this chapter and all the others. The intro is loosely based on the Prehistoric Park intro.

And here we go!

(Play Prehistoric Park intro music)

We see a map of Remnant

There is something that does not belong in our world.

We see various prehistoric animals

The amazing animals that time has left behind.

We see an anomaly

But what if they could come back?

We see a T-rex skeleton

What if extinction wasn't forever?

We see a T-rex doing its iconic roar.

An anomaly opens up

We see Ruby running from Allosaurs

We're going on a mission with a twist

Matt encounters a herd of sauropods

As future huntsman Darrel Maximus races through time

We see Darrel face off against a Carcharodontosaurus and then the rest of RWBY and DIMD running amongst a herd of dinosaurs

To save his home from creatures of prehistoric proportions

We see him running into an anomaly away from a Giganotosaurus

His mission is to contain these creatures and return them to their own time.

We see his friends all running towards Darrel as a T-rex who is facing a cliff. He turns his head towards them as the sunlight catches his head.

This is the ultimate prehistoric mission.

He roars loudly

This is…RWBY: PRIMEVAL!

Vale Subway

Multiple people were boarding the subway. Most of them had weapons on them, for even down here, lurked Grimm.

As a woman attempted to open a window, she felt something prod her back. Quickly turning around, she saw it was a huge spider! With fear, she slammed the window down closing it, severing one of its legs in the process. She shrieked in fear.

The spider retreated to another tunnel, where multiple other large spiders were.

Noon

Beacon

Darrel was in the library working on a project when Blake walked up to him.

"Hey."She greeted. "Hello, Blake. I'm busy working on a project for ar. We have to recreate a moment in our lives."He explained.

Darrel's project was a diorama that contains a figure of a T-rex shooting a blue heat ray from its mouth at a Nevermore figure.

She kissed his cheek. "Cute." "I'm almost done; I just need to add-in more details."

They heard Glynda call RWBY and DIMD to Ozpin's office.

After dropping off his project at his dorm, they arrived at Ozpin's office. There they saw a woman who had similar attire to Glynda and looked like her, but her hair was a darker yellow tone with some grays and whites.

"This is my Endora Goodwitch, my mother. She had an encounter with what exactly?"Glynda stated.

"A giant spider! It was big as my head!"She said, still scared.

"That sounds like something from the Carboniferous, the era of giant bugs."Darrel stated.

"Since this happened in a subway tunnel, I've had the mayor shut down the area where the event occurred. Also, Imperious will be going with you as he has experience dealing with underground Grimm; he will be waiting for you at the airships."Ozpin explained.

As they were leaving, Coco flagged down Imperious and kissed him. "Be safe, love."She said before she left.

As he boarded the airship, Imperious saw their looks. "Not one word."

Vale Subway

The 9 arrived at the entrance to the closed down subway area. Since it was dark, everyone turned on flashlights they had installed on their weapons. However, when Ruby saw Imp's weapon, she lost it.

"IS THAT….A GUNLANCE?!"She shouted.

"Yes, and I made it myself. I call it Longinus. It can also be filled with Dust crystals." Longinus was pure black with gold highlights and the blade was dark blue.

"How are you able to wield it?"Isaac asked, curious. "Years of experience."

As they walked down the tunnel, they heard something skittering about.

"Early wanderer."Darrel proclaimed.

He convulsed in pain. He grew slightly bigger and he switched to a quadruped stance. His head grew bigger and was filled with needle sharp teeth. Neck grew thicker. Limbs sprawled out to the sides and ended in short claws. He grew a long tail that came to a tapering end.

He had mottled scales all over and white stripes going over the top of his back. His eyes were orange yellow.

Darrel was now an 8 foot long Proterogyrinus.

What was the cause of the skittering, was a 10 feet long centipede with red chitin.

"Arthropleura, large centipede; herbivore."Darrel said in a low growling voice.

The massive centipede reared up at Darrel. He hissed at it and then tail whipped it in the side of the face, sending the large centipede into retreat.

They continued trekking when they heard loud flapping, much like a bug's wings. Weiss shined her flashlight to see two massive blue, red eyed dragonflies fly towards her.

Without thinking, she panicked as the two dragonflies flown around her light. Blake fired a shot in the air, spooking them and sending the bugs deeper into the tunnel.

"What were they?"Weiss stated, still scared. "Meganura, predatory dragonflies as big as an eagle."

They soon arrived where the incident occurred and came across a room that would have been a room for the workers wasn't it for the multitude of giant spiders all over the area. (The spiders look like the spiders from Walking with Monsters.)

"Ok the plan is shine your lights at them, scare them up while I locate the anomaly."Darrel explained as his team, RWBY, and Imperious shined their lights everywhere while Darrel found the anomaly as soon as he saw the abdomen of the Arthropleura go in. It wasn't long before all the spiders had entered the anomaly and it closed.

Darrel changed back and they left the room.

However, just as they left the room, the ground began to vibrate. "Now what?!"Dalton said, annoyed.

Bursting from the ground was a new breed of Grimm.

It resembled a Hercules Beetle, but was as big as an Asian Elephant. It was heavily armored all over, even its six legs which ended in short claws. Its head was covered in a massive plate and it had 8 eyes, four on each side of its upward curving horn. The massive horn on top had several spikes going down it.

"What is that?!"Yang asked, rather intimidated. "That is a Heracles."Darrel explained.

Things were about to get worse.

Skittering in from the ceiling was a centipede Grimm 20 feet long. It sported a massive pair of tusks near the front of its head and it had six eyes. (Basically this resembles the Arthropleura from Primeval.) "And that is an Arthros."Imperious explained.

"Ok here's the plan: I want the heavy hitters to focus on the Heracles, while the others deal with the Arthros."Ruby commanded.

Ruby, Weiss, Blake, Isaac, and Matt went after the Arthros while Yang, Darrel, Dalton, and Imperious attacked the Heracles.

Darrel as a 20 feet long, 440lb gray crocodilian scaled, with yellow crocodilian eyes Quinkana was currently on top of its back, biting and clawing away at its armor looking for an opening. Yang was doing the same, albeit bombarding it from afar.

"Screw it!"Dalton leaped into the air, Oh Mercy Baby raised up and preparing to cave its skull in only for the bug to swat him aside with its top horn.

Enraged, Yang jumped into the air, straddling its nasal horn and punching away at its skull piece. Imperious kept stabbing it with Longinus infused with yellow dust, managing to slice off 2 of its legs.

Meanwhile with the Arthros, the creature was moving too fast for them to get a clear shot in. Matt was able to clip one of its tusks off and Isaac shot off a few of its legs.

Weiss came up with a plan to lock it in place with a holding Glyph which was infused with yellow dust, electrocuting it. Paralyzed, Ruby dealt the final blow by slicing it two as the waist.

As for the Heracles, it was extremely crippled: its armor had multiple chips in it, some pieces were missing, and its exposed flesh was already burning, and 3 of its legs were severed off. Imperious dealt the fatal blow by throwing Longinus infused with red Dust into its skull plate, piercing its head. The head erupted into flames before it fell dead.

Imperious pulled Longinus out when he felt something land on his head. He picked it off to see it was a lizard with green scales and red eyes. "That is a Petrolacosaurus, one of the first lizards to evolve. It must have gotten left behind."Darrel explained.

Imp stared at lizard with curiosity. "I think I keep it."

Imperious and Coco were tangled on her bed, making out. "So, how did the mission go?"She asked.

"Great; with some help, I killed a Heracles and I got a prehistoric pet lizard whose name is Klaus."He stated.

Just before they continued, the rest of CFVY walked in….only to get blown out the door, literally from Imperious wind semblance.

And that wraps up another chapter! Now, this one did borrow a couple elements from the bug episode of Primeval which is not bad, right?

Also, tell me what you think about the review; is it good or bad and does it need improvements?
