BGM: Demon Train - The Legend of Zelda: Spirit Tracks

Teams RWBY and ALPN, and their leader Qrow, were now aboard the subway. Qrow addressed the party, "Let's make this quick. We gotta get to the front of the train."

Oleana raised her hand. "Mister Branwen?"

Qrow looked at her.

Oleana pointed to something inside the train car. "What's that?"

Qrow analyzed the object before answering, "That...is a bomb."

Ruby pointed ahead. "We've got company!"

Up ahead, a few cars away, a bunch of White Fang grunts were emerging from the train and climbing onto the roof.

"Well," said Aris, "I guess we shouldn't expect them to go-"

The bomb inside the train car beeped; it was about to detonate.

Aris finished. "-easy on us."

"Time to go!" said Nash as he leaped onto the adjacent train car.

Qrow turned to Blake. "Detach the caboose!"

"On it!"

Blake went down below to detach the rear car of the train, but then called out to the party, "It decoupled itself!"

"Guess he really wants us off this train," Pit said.

Some distance behind them, the detached caboose exploded. Aris gasped. "Oh, not good!"

"Uh, neither is this!" Ruby exclaimed.

"Another bomb?!" cried Qrow. "This is getting out of hand, now there's two of 'em!"

Weiss went to the next car in front and opened the rooftop hatch. "They all have bombs!"

The bomb nearest the students beeped. Aris turned to everyone. "Jump for it!"

With that, the party joined Weiss on the next train car. "This doesn't make sense!" said Yang.

Ahead of them, the White Fang grunts were advancing. A female deer Faunus pointed to the students and shouted, "Get the humans!"

Team RWBY went forward to dispatch the grunts. "We'll deal with them!" said Ruby. "Team ALPN, go with Qrow and get to the front of the train! We'll try to meet you guys there!"

As it turned out, there was no need. The White Fang grunts were easily disposed of by team RWBY and their weapons. "Never mind!" said Ruby.

Behind the train, another car exploded. It opened holes in the tunnel walls, and the worst thing imaginable emerged: Grimm. There were several species, one of which was a King Taijitu, and a Tyranitaur. There was even a Grihmanox - a spider-like Grimm with a singular, massive eye that cried tears of venom.

"Oh, god..." breathed Qrow. He turned to the students. "He's leading Grimm to the city! It's the cars! They're detaching and blowing holes in the tunnel, which allows Grimm to enter!"

"That's insane!" cried Oleana.

Aris cracked his knuckles. "We've gotta do this, and fast."

Qrow addressed Yang, Weiss, Blake, Pit, and Oleana. "You guys, go below and try to defuse the bombs!"

"What about us?" said Nash.

Qrow narrowed his eyes. "We're stopping this choo-choo train."

"I know," said Aris. "I said that earlier."

While the rest of the group went below and into the train cars, Ruby, Nash, Aris, and Qrow (as well as Aris's Pikachu) ran towards the front of the train. Qrow pointed. "Up ahead!"

A few cars away, a bunch of White Fang grunts were boarding the Atlesian Paladins that were loaded onto the train. "We've got a problem!" said Nash.

Aris snapped his fingers. "And I've got an idea! Pikachu!"

The Pokemon looked at him.

Aris smirked. "Use Spark!"

Pikachu's body crackled with forking arcs of lightning as she bolted for the incoming Paladin. The mechanical menace was destroyed upon impact.

Another Paladin arrived, looming over the Electric type.

Qrow leaped into action, drawing his sword and slicing the Paladin to pieces.

Soon, a third Paladin jumped into battle. Nash hacked off its leg with Exorcism, sending it flying off the roof of the train.

Qrow addressed Aris and Ruby. "You two, go on ahead."

Ruby tried to protest. "But-"

Her uncle cut her off. "Don't worry, kid. 'S time I teach them a lesson. Aris, you keep her safe for me."

"I won't let you down!" Aris said.

He was about to leave, but Pikachu tugged on his leg. "Pika..." The Pokemon was worried about her trainer.

Aris knelt down. "Go help him, girl."

Pikachu nodded, then sprinted off to aid Qrow.

Everyone who'd gone below emerged and climbed onto the roof of the train. They stood by Aris's and Ruby's side.

Up ahead, the train was about to collide with the blockage that sealed off the tunnels.

"What now?" said Oleana.

Weiss stabbed Myrtenaster into the train roof, encasing herself and her comrades in ice.

The train collided with the barrier with a resounding BOOM!

End BGM

Aris opened his eyes. His head hurt like crazy.

He was among a pile of rubble, with people strewn about it. His teammates, and team RWBY. He promptly went to check on Ruby to see if she was unhurt. She hadn't sustained any injuries.

Aris sighed. "Finally."

The ground shook.

With a blood-curdling scream, the King Taijitu emerged from the ground, various other Grimm pouring out of the hole along with it. The Tyranitaur emerged with a resounding roar.

Nash sighed. "Welp, here we go again.
