The team gets down into the hole silently. Down there, they saw a door in front of them and 2 guards are guarding it. They drop down and hide behind the boulders. Weiss talks to Y/n.

Weiss: *coms* Great, how do we get past those 2 without being spotted?

Y/n: Hmm, *looks Blake and coms* Say, how good is your aiming with your pistol right at this distance?

Blake: *coms* Kinda good at this distance. Why?

Y/n: *coms* We'll take them out together. One target each.

Blake: *coms* How? Our guns are too loud.

Y/n is keeping an eye on them one of them is going back inside.

Y/n: *coms* Catch. *throws a suppressor and a red-dot thermal scope*

Blake: *caught it* What's this? 

Y/n: Take your weapon into gun mode and attach those to your gun. *gets his Onic Time into SMG mode and single-fire mode and attached a red-dot thermal scope and a suppressor*

Blake does what Y/n did she turned her Gambol Shroud into Gun mode and managed to attach the scope and suppressor.

Blake: Okay, now what?

Y/n: *aims at the WF guard* Use your thermal scope to spot my laser.

Blake: *aims her gun and looked through the scope and sees the laser* I see it.

Y/n: I got his buddy you get the other. If one of the guys gets out of the door to find his friend, Yang, I'll fire a flash smoke grenade on him and you drop kick him and close the door.

Yang: Got it.

Y/n: Okay Blake, on your go.

Blake shots the guy while Y/n did the same.

Blake: Dumped him.

Y/n: Clean shots.

They move forward while Yang is still on stand by. But suddenly...

WF: Hey, what's taking you so quiet-

Y/n gets his gun and throws a flash smoke grenade

Y/n: Yang, now!

Yang drops down and just drop attack the WF thug. Yang closes the door and Y/n interrogates the WF knocked out.

Y/n: Where's Roman Torchwick keeping the hostage?

WF Thug: You ain't gonna kill me. You ain't gonna kill me!

Y/n: *points the gun near his face* Do I look, like a simple Hunter to you? Rethink your answer before I fill you up with rubber.

WF Thug: Behind that door, the train tracks! But you ain't gonna get them! He knows all of you are coming, freaks!

Y/n: Good *shoots the gun and the thug now has a big bruise on his forehead and unconscious*

Oobleck: I'm interested at your tactics, but let's not waste time.

They entered the door and saw multiple enemies. They're just patrolling the area.

Y/n: *reverts back to Starfall Knight* Let's cause some chaos.

Timeskip

While on Roman's case, Ruby is held as hostage, but as soon as he's about to continue3 his little play, an explosion was heard.

Roman: Oh, what the-? *clicks his tongue* Perry, if you and the boys could take care of that? Kind of in the middle of something.

White Fang thug leader nods and goes to the scene, but then another explosion occurs. Roman has enough of it.

Roman: What is going on here?!

Another explosion happens again and this time, White Fang thugs are running as they fired to the team, but some were not so lucky as they get shot by Y/n's bullets. Roman saw this but he's caught off-guard as Ruby use this opportunity to run back to her team.

Roman: Somebody kill her!

They fired to Ruby but every shot is missed. Roman gets furious and almost breaks his cane. He ordered his men to do it.

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

WF Thug: But we're not finished.

Roman points his cane towards the thug's neck and lifts him.

Roman: Do it, or you're finished!

Ruby is about to escape when she's gonna run through the remaining WF armed with rifles, but suddenly they got wiped out when a explosive round hits them from behind.

Yang: Ruby!

They both embraced each other as the rest of the party tends to them.

Weiss: Are you okay?

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

Blake: What? *hands over the Crescent Rose to Ruby *

Ruby: *checking her weapon* Androids, mechs- they're all loaded up on train cars.

Oobleck: Ah, that's ridiculous! These tunnels are sealed. The tracks lead to a dead end.

Y/n: Unless they are really intended on going with that plan.

Roman speaks to the loud speaker

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

Just then the train starts up and running, as it's cargo are also moving.

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

Ruby: We need back up. Let me call Jaune.

Y/n: No shot Ruby.  Tried to call you before, but there's no signal down here.

Weiss: So, what do we do?

Oobleck: I believe we only have one option.

Y/n: Well, no choice.

Ruby: We're stopping that train.

Y/n: Okay. All aboard.

The train is about to gain speed when the team gets in it right on time. One of the WF thugs saw a glimps of Ruby's Semblance and tries to call Roman.

WF Thug: Uh, sir, I think they're on the- *knocked unconscious*

Oobleck knocked out one of them. But on the main control room, one of the thugs alerted Roman.

WF Thug: Boss! They made it on the train!

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

The thug closes it after hearing Roman's tone at him.

Roman: Manic animals, every one of 'em. *saw the driver looked at him feeling like his pride is hurt* Not you though, you're, *nervous giggle* you're great.

At the top of the train,. the team needed a plan on how to stop the train before it hits the dead end.

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

Y/n: *opens the lid of the cargo* Uhm about that...

Weiss: *she saw what Y/n meant* Uh, Doctor?

Oobleck: What?

Weiss: What's that?

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

Y/n: And a well armed one too. 'Why does it look like from the Arkham Knight game though but mini version?'

They're surprised about it that it's a well armed military-grade bomb. But then Ruby found another bad news.

Ruby: We've got baddies! *points the other carts' lid opened with WF thugs climbing up the top* 

Oobleck: Well, I didn't expect them to go... *bomb's armed and about to explode* easy on us.

Y/n: Everyone, jump to the next one! Blake cut the cables!

Blake: I'm on it!

Blake goes to cut it but it detaches by itself.

Blake: It decoupled itself!

Oobleck& Y/n: What?!

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

Then the cargo exploded behind them.

Oobleck: That's not good.

Ruby: Uh, neither is this!

Y/n: Another one?!

Oobleck tries to assess the situation and finds out.

Oobleck: No, no, no... *jumps to the other cart and opens the lid*

Oobleck saw another bomb, the same thing that detonated on the last cart.

Oobleck: They all have bombs!

But then the next bomb is detonated.

Y/n: Guys, jump!

They all jump to the next cart.

Yang: This doesn't make sense.

They look behind to see other WF getting close to them.

WF thug (G): Get the humans!

Team RWBY starts fighting the WF, while Y/n and Oobleck tries to understand what they're planning. The cart explodes again but it created a hole in the tunnel's ceiling, making the Grimm come out of their hiding, the Alpha of the Beowolves is here. 

Y/n: Well, that's bad.

Until a giant slithering black scaled Grimm started to slither and it appears itself, the King Taijitu has joined the party and roared commanding the army to chase the humans.

Y/n: Okay, well that's worse!

Oobleck: Oh... dear. He's leading the Grimm to the city!

Weiss: What?!

Y/n: It's the cargos! They detach and explode, creating openings for the Grimm!

Blake: That's insane!

But then another cargo is detached.

Oobleck: We have to hurry! You three! Go below and stop those bombs! 

Ruby: What about us?

Oobleck: We're going to stop this train.

Ruby: Yeah, I know.

Y/n: Let him have this moment, Ruby. But that's not the time for drama let's go!

Oobleck: Y/n's right, let's not waste time!

But then WF has access to the Paladin's.

Oobleck: Up ahead!

It landed in front of the three, Y/n smiles.

Y/n glows & changed his battle gear into the Holy Blade gear and abilities, he landed close to it as well.

Y/n, Gusion: *smirks* Now begins the fun part.

Y/n launches his daggers with the use of his skill <Shadowblade Slaughter> to hit the joints and then use <Sword Spike> to hit the main power core and then blinks through the power core but he didn't call the daggers back to him. Instead, he teleports behind it, resetting the of <Sword Spike> and <Shadowblade Slaughter> cooldowns. 

Y/n, Gusion: Off with you!

Then he launches <Shadowblade Slaughter> and <Sword Spike> to the Paladin. and dashes using the 2nd phase of the <Sword Spike> and calls back the daggers to him. It exploded into pieces.

Y/n & Gusion:  Pointless effort. *puts the dagger back to the holster*

Oobleck: Hm. *drinks the coffee and smirks after that*

He transforms his weapon and Zwei jumps turning him into a ball. Then Oobleck acted his weapon as a baseball bat and hits Zwei, making their attack hit through the Paladin easily, the Paladin then exploded as it rolls it's way to its explosive demise. While Oobleck finishes the another Paladin.

Timeskip

 The three is inside the train and Blake and Weiss just splits up. Now Yang faces Neo, but someone interrupts their fight.

Y/n: Yang, I got this girl. You help Blake and Weiss, they're in trouble.

Yang: Wait when did you?

Y/n: I got this. Now go.

Yang just nodded and goes to the rest of her team. Then Neo and Y/n just circled around each other, staring at each other.

Y/n: So, when was the last time we ever fought?

Neo: How can I forget, the one when you rescue me back then. Also back on the bridge.

Y/n: The bridge doesn't count. That's barely even called a spar.

Neo: So, what's this now, hm?

Y/n: Call it an offering spar.

Neo: Offering spar?

Y/n: Whichever one of us wins, gets the ice cream strawberry and chocolate.

Neo: *smirks and arms her umbrella* Ohohoh, now you're talking.

Y/n: *arms his Light Ray blade* Let's do this.

They both clashed and Neo makes her first move  she launches her umbrella towards Y/n but Y/n blocks it but he didn't know that Neo's umbrella has a grapple gun function like the Kingsman does, so she dashes herself towards the umbrella to retrieve it back, making Y/n pushed back a little bit.

Y/n: Clever, but not good enough.

Y/n's turn he calls the daggers behind Neo & Neo blocks it, but Y/n kicks her from behind after she's done blocking the daggers. Then punches her chest, she's  pushed back a little bit as well.

Neo: Heh, never thought you could punch a woman's chest.

Y/n: *smirks and clenches his fist* This is just the warm-up. 

He transforms into Masha's abilities with her gear in Dragon tamer, his hair turns blonde yellow and he let Masha take-over making the hair grow longer.

Masha: Let's spice it up shall we?

Neo: With pleasure. *licks her lips*

They collided each other with their umbrellas and fists. Everyone can felt the intense battle too. They thought who's causing this much impact and shaking. Masha keeps fighting Neo, until she finally gains the upper hand and disarmed her, and Masha pins Neo to the wall, with her arms pins to the wall also, looking like a close lovely couple.

Masha: I win. But let's call it even you still got more room to improve. But you're so strong unlike last time.

Neo: Figures. *smirks* So, do you want to... you know.

Masha: Maybe next time.

Neo: Why?

Masha: She's here.

Just then a blade suddenly tries to strike Masha, it has a mask with a sword in red blade. But she blocked it as Masha mentally communicates Neo.

Masha: {Escape now, Neo}

Neo nodded and left. Masha pushes the masked assailant back, and the sword user changed blades into ice blade. She engages and Masha blocks all of her attacks.

She broke the blades with her gauntlets and the sword user changed blades into thunder blades. Masha reverts back to Y/n's form and he gets his dual blades RSG. He attacks her with <Double Circular>, <Inferno Raid> and blocks the masked assailants attack with <Cross Block>. When the masked sword user has enough, he suddenly changes into Benedetta.

And he let her take control over Y/n's body. She blocks the attack and clashed blades with her with just her basic attacks, <Elapsed Daytime> & <Phantom Slash> until she manages to back her off.

???: You're not my daughter.

Benedetta: Does Yang matter to you now? You know what, we don't care. Get out of here before she sees you.

The masked assailant suddenly just turns her back to Benny (A/n: Nickname of Benedetta when she was a kid) and creates a portal and leaving. Benedetta goes back to Y/n form and let Y/n rest a little bit. Yang enters the cargo that Y/n is in and sees a glimpse of her mother and she blinked her eyes to see she's gone.

Y/n: Hey, Yang. You okay?

Yang: I should be asking you that. Did you see her?

Y/n: I know. But that's not the time. Come on.

Yang: Fine.

They separate ways. As Y/n go into the control room, while Yang goes to her teammates.

WF Thug: Wait how did you- *slashed*

Y/n: Shut up. Okay, let's see *tries to hack in but it can't* Tsk. *calls Summer* Summer can you hear me.

Summer: [I know, I'm trying to hack it to stop the train but I think they realized that I'm hacking. So they cut it off and intended to make this thing even faster. Can they trace us back?]

Y/n: They won't. The computer we had is much advanced than theirs it's secured. 

Summer: [So, what now?]

Y/n: Prep the car and your gear. I've got a bad idea.

Summer: [Please don't tell me...]

Y/n: Yeah. Sorry, no other options left.

Summer: [*sighs*Just make sure my daughter's alright]

Y/n: I know. *ends the call and calls the team*

Oobleck and Ruby are done with their Paladin battle but another one is coming. 

Oobleck: Ruby! You go on ahead!

Ruby: But-

Oobleck: Don't worry, Ruby. Its time I teach them a lesson they won't forget.

Ruby saw this and sees Zwei with a sad look.

Ruby: Go.

Zwei goes to help Oobleck, while Ruby goes on to the front of the train but stops when each team sees their phone that Y/n is calling. Team RWBY gathered and answer the call.

Ruby: Y/n, where are you?

Y/n: I'm at the control room but never mind that. The dead end is getting close. 

Weiss: So what's the plan?

Y/n A bad one, I have.

Blake: What do you mean by that?

Y/n: Time to go out this one with a ,*sigh* Yang. If you get what I'm planning.

Yang: *laughs but her laughs faded that she gets what he meant to do* Wait... You're not serious are you?

Y/n: This is serious now! It's getting closer, so prep yourselves! *ends the call*

Ruby: Got it. Weiss!

Weiss: I'm on it.

Weiss stabs the train car their standing on and created a dome shield for all of them.

Y/n:

And they ram through the dead end, as the screen goes white.
