A/N: You, Team RWBY and Oobleck try to stop a train heading to vale.

Ruby was thrown across the floor by Roman. And Frost, who was with him as well, just smirked in amusement.

Roman: Wow! You are much more manageable without that oversized gardening tool of yours.

Ruby got up and charged at Roman, but he simply sidestepped and sent Ruby stumbling across the floor.

Frost: simple minded human.

Roman: Oh man. You know, Perry, I really did need this.

Perry gave a thumbs up in agreement as Roman laughed. He soon walked over to Ruby and aimed his Melodic Cudgel at her.

Roman: But seriously. How'd you find this place, Red?

Ruby growled and used her Semblance to escape Roman and start running for an exit.

Frost: Annoying little brat!

Frost charged and caught up to Ruby by hitting her in the back and then pulling her up by her hair.

Ruby: Ahhh!

Roman: I see you've got some tricks up your sleeve! Let me make this clear: We're not through here yet.

Frost: On the contrary, I say there should be no witnesses.

Frost said as he pointed it at Ruby's head. But before he could even fire, a (F/C) colored light burst through the roof and landed so hard in the ground it made large cracks. Both Frost and Roman saw that it was you. And you look pissed.

Roman: Oh.......

In just seconds, you got near Frost and punched him so hard in the chest, 3 of his ribs shattered before being sent flying. Then, you appeard to Roman and gave him a heavy smack on the face with your tail, which knocked a tooth or two out of his mouth. He fell back and looked at you while small bits of blood poured from his mouth.

Roman: Grrrrr, why you.......

Explosions were soon heard as multiple White Fang members came running around the corner, some firing at who would soon be seen to be Weiss, Blake, Yang, Zwei and Oobleck. Ruby took this as and opportunity to escape and run to her friends.

Roman: Somebody kill her!

You were about to knock out Roman, but a furious frost lunged at you and slammed you far from them and against a wall.

Frost: I'll gut you like the pig you are!!!

You headed butted Frost right in his forehead before proceeding to knee him in the nuts. Frost widened his eyes groaned in pain before you wrapped your tail around his neck and slung him away into an old building, which soon collapsed on him. When you turned to Roman and the White fang, you saw them opening fire on Ruby who dodged their blasts. You fired death beams at them and got a few White Fang members in their legs. Roman growled and turned to one of the members next to him.

Roman: Attach this cart and spread the word: We're starting the train.

White Fang Member: But we're not finished!

Roman: Do it or you're finished!

Ruby kept running but soon stopped when as she saw a group of White Fang members. But a huge explosion from behind them sent them all flying and reveling Yang behind them. Ruby ran and jumped into her arms.

Yang: Ruby!

Weiss: Are you okay?

Ruby: I'm fine, I'm fine! But listen! Torchwick's got all kinds of weapons and robots down there.

Blake: What?!

Blake handed Ruby her weapon.

Ruby: Androids, mechs, they're all loaded up on the train cars!

Oobleck: Ahhhh, that's ridiculous. These tunnels are sealed, the tracks lead to a dead-end.

Roman then spoke across the speaker system.

Roman: Get to your places, we are leaving now!

The train started moving toward the tunnels.

Yang: Well, it sounds like they're going somewhere.

Ruby: We need backup. Let me call Jaune.

Ruby's Scroll flashed "Low Signal".

Ruby: I can't get through!

Weiss: So, what do we do?

Oobleck: I believe we only have one option...

Ruby: We're stopping that train!

(Y/N): We better hurry.

The train rushed through a tunnel, loaded with mechs. A White Fang member stood on the train soon heard a noise and looked outside the train to see rose petals. He brought out a communication device.

White Fang Member: I think they're on the.....

The White Fang member fell down as you hit him in the head with your hand. In the front of the train, Roman and a White Fang member rushed in.

White Fang Member: Boss! They made it on the train!

Roman sighed in annoyance.

Roman: Then grab some cargo and get them off the train!

The White Fang member nodded and left to follow Roman's orders.

Roman: Man, animals, every one of them.

Roman then looked awkwardly at the White Fang member sitting next to him.

Roman: Not you though, you're, heh, you're great.

You, Team RWBY and Oobleck were standing on top of the train.

Oobleck: Hurry, children! We must get to the front and stop this train!

Weiss: Err ...Professor?

Oobleck: Doctor...

Weiss: What's that?

She said while pointing down a hatch into the train. Oobleck kneeled down to get a closer look.

Oobleck: That my dear ...appears to be a bomb.

You all crept away from the hatch.

(Y/N): Crap!

Ruby: We've got baddies!

Dozens of White Fang members were soon climbing onto the top of the train.

Oobleck: Well, I didn't expect them to go...

The bomb underneath you guys charged up and started beeping.

(Y/N): 😐

Oobleck: .....Easy on us. Time to go!

As You and Team RWBY started running, Oobleck stopped Blake.

Oobleck: Blake! Detach the caboose! It will kill us all!

Blake: On it.

Blake jumped down onto the connectors and got ready to cut the connection, but as she did, the connection came loose on it's own.

Blake: Huh? It decoupled itself!

Oobleck: What?!

Yang: I guess he really doesn't want us on this train.

As Oobleck looked back at the detached cart, it exploded in the tunnel.

Oobleck: That's not good...

Ruby: Err, neither is this!

She said standing next to another ditch.

Blake: Another bomb?!

(Y/N): Seriously?!

Oobleck looked around and ran to the next train car.

Oobleck: No. No. No.

He opened the hatch and looked in, then yelled back to you and the girls.

Oobleck: They ALL have bombs!

The bomb under Team RWBY charged up and started beeping and the cart you were on detached itself, forcing you to run to the next cart.

Yang: This doesn't make sense!

The White Fang members kept climbing the train.

White Fang Member: Get the humans and Arcosain!

All of you jumped forward to attack the incoming White Fang members. Oobleck turned around and watched the detached train car explode. Only this time it created a hole allowing multiple types of Grimm to emerge.

Oobleck: Oh, dear...

The horde of Grimm begin advancing quickly toward the runaway train.

Oobleck: He's leading Grimm to the city!

Weiss: What?

(Y/N): That twisted snake!

Oobleck: It's the cars! They detach and explode, creating openings for the Grimm!

Blake: That's insane!

Another train car detached itself.

Oobleck: We have to hurry!

He turned to Weiss, Blake, and Yang.

Oobleck: You three, go below and try to stop those bombs!

Ruby: What about us?

Oobleck: We're going to stop this train.

(Y/N): Sounds like a plan to me.

Ruby: Yeah, I know. I said that earlier.

The group moved forward. As the train continued towards it destination, White Fang members started to pilot multiple Atlesian Paladin-290s, and jump to the top of the train. You, Ruby, Zwei, and Oobleck were running towards them.

Oobleck: Up ahead!

A Paladin started charging toward you.

Oobleck: We got a problem!

(Y/N): More tin cans for the scrap heap!

Oobleck took a sip from his thermos before transforming it into its weapon mode, a small flame burning at its tip.

(Y/N): Well, I'll be damned! 0_0

Zwei barked as prompted that he was ready for an attack. He jumped and flipped in the air, and Oobleck batted him, turning him into a small fireball. The Paladin shot at him, only for it to get knocked off the train by the combination attack. The Paladin tumbled on the train tracks, and exploded when it hits a barricade.

(Y/N): Okay .........that was awesome!

Another Paladin appeared in front of Zwei with it's guns aimed at him. Suddenly, multiple attacks were fired from you and Oobleck before swiftly knocking it off the train as well. Down below, Yang, Weiss, and Blake entered the train car.

Yang: I guess this is what we trained for.

Weiss reached into her pouch and gave Blake a magazine filled with Dust vials.

Weiss: Here, this should help you.

Blake slide the mag into Gambol Shroud, and then the three of them charged forward. Suddenly, the pink and brown haired girl from before named Neo, dropped from the ceiling and blocked their path.

Yang: You two go on ahead. This one's mine.

Blake and Weiss proceeded forward. As Neo prepared for their attack, Yang fired a round to distract her, allowing Blake and Weiss to continue. Yang stepped forward towards her opponent, staring down as Neo gave a sinister smile. The two begin their fight. In the next train car, Blake and Weiss were running, and then looked at each other when they heard the sound of revving up ahead. The White Fang Lieutenant was ahead of them while dragging a chainsaw along the floor.

Weiss: You go on ahead!

Blake: Got it!

The Lieutenant chuckled menacingly as he held up his chainsaw. The two Huntresses-in-training charged forward, with Blake deflecting an attack as Weiss flipped backward. Weiss delivered multiple strikes at the Lieutenant, knocking him down. She then smiled at Blake as she proceeded to the next car. The Lieutenant got back up, again chuckled menacingly.

White Fang Lieutenant: Finally, I get to kill a Schnee...

Weiss held up Myrtenaster en garde.

In the next train car, Blake stopped and grind her teeth when she's greeted by Roman.

Roman: Hello, kitty cat. You miss me? You know, we really gotta stop meeting like this. People are gonna talk...

Blake charged forward to attack, starting their brief battle. She soon knocked him down, and when he attempted to get back up, Blake stepped on his chest and pointed her sword at his throat.

Roman: Why are we fighting? I saw you at the rally, we're on the same side and you know it...

Meanwhile, Weiss was fighting the Lieutenant. But Things took a turn for the worst.

White Fang Lieutenant: C'mere, princess!

The Lieutenant grabbed Weiss' face and slammed her into the floor, knocking her unconscious. He then threw her in the air, readying to hit her with his chainsaw. Yang's fight was going badly and soon ended when Neo managed to throw her into the ceiling, knocking her unconscious. Neo turned around to approach Yang. back to Roman being held down by Blake, he grunted as she points her blade at his throat.

Roman: Oh, still feisty. Soooo, what are we gonna do now? You think a little bow on top is gonna make people forget who you were? What you've done...?

As she grind her teeth at his words, Blake heard the door from the previous train car open behind her. An unconscious Weiss was thrown to the floor, with the Lieutenant emerging from the doorway, holding his chainsaw.

Roman: So what's it gonna be, Blake?

She sheathed Gambol Shroud and kicked Roman in the face, knocking him unconscious. Blake went over to Weiss' aid, and fled immediately before the Lieutenant could reach them. Meanwhile, Neo pulled a hidden blade from within her umbrella and approached the unconscious Yang. She prepared to deal the finishing blow, grinning sadistically while doing so. Suddenly, a masked warrior, raven-haired and clad in red and black, came out of nowhere and knocked Neo back. Neo's eyes change from brown and pink to white, mirroring her fearful expression. The mysterious swordswoman slowly drew her long and crimson sword again and held it up intimidatingly. Neo, realizing the imminent threat before her, wasted no time and disappeared in a flash. The swordswoman looked down at the still unconscious Yang, and slashed her sword to the side, opening an eerie red portal. She walked away from Yang and into the portal. At that moment, Yang regained some consciousness and slowly got back up. As she opened her eyes again, she got a brief glimpse at her rescuer before the woman disappeared. Yang rubbed her head, still reeling after just regaining consciousness, before standing up and leaving the scene. Back to You, Ruby and Oobleck, the Doctor dodged a couple swipes from the Paladin, and then ran to the top of it'svhead, and shot it in it's engine before jumping back down. Ruby twirled Crescent Rose around a few times, and then she and Oobleck fired simultaneously at the Paladin's feet, knocking it off the train. Two Paladins tried to attack you, but you used energy disks to slash one of their legs off while ripping off the arm of the other one and using it to knock them both off the train. As Ruby and Oobleck were moving, they both switched positions.

Oobleck: Ruby! You go on ahead!

Ruby: But......

Oobleck: Don't worry, Ruby. It's time ...I teach them a lesson...

The Doctor went to take on two more oncoming Paladins. You were about to join him until you spoke.

Oobleck: Do not worry about me, (Y/N). I'll take care of this. Go with Ruby.

(Y/N): You sure?

Oobleck: I couldn't be more Positive.

You nodded and went with Ruby. But before you both left, Ruby noticed the saddened Zwei looking up at her. She smiled and motioned for him to go join Oobleck.

Ruby: Go.

With that, Zwei barked happily before running off to fight alongside the Doctor. You and Ruby hurried to the front of the train. The remaining members of Team RWBY reemerged from the train cars to rejoin you two. Ruby soon realized the train was on a collision course with a thick concrete wall.

(Y/N): ...........Oh you gotta be kidding me!

Blake: What do we do?

You quickly reacted and soon appeared a couple of feet from the train thanks to afterimage. You stood your ground while you spreaded your arms out.

(Y/N): You! Shall Not! Pass!

The train collided with you with your hands pressed against it. But it was still pushing you back. Weiss then formed an ice shield to protect her and teammates, bracing themselves for the impending crash. The train crashed into the wall, causing the explosion and everything to go white. After a while, you woke up and saw that you were all in Vale. But, so was a hoard of Grimm. Ruby and her team looked at the Grimm with anger and determination. You did the same as you slowly powered up.

(Y/N): Alright, let's waist these dicks!

A/N: These Grimm better get ready to die.
