We see the overhead of the deserted alleyway with a graffiti-marked dumpster as Penny reveals her secret to Ruby and Nick.
Ruby: "Penny, I-I don't understand..."
Penny: "Most girls are born, but I was made. I'm the world's first synthetic person capable of generating an Aura. (Turns her head to the side sadly.) I'm...not real..."
Ruby: (Takes Penny's hands into her own.) "Of course you are. You think just because you've got nuts and bolts instead of squishy guts makes you any less real than me or Nick?"
Nick: "Ruby is right, you know?"
Penny: "I don't...um... (Leans in close to Ruby and Nick's faces) You're both...taking this extraordinarily well."
Ruby: "You're not like those things we saw back there. (Taps her chest.) You've got a heart, and a soul; I can feel it!"
Nick: (places a hand on Penny's shoulder, while giving her a warm smile) "Same here."
Penny: "Ooohh...oh Ruby, Nick (Grabs Ruby and Nick into a hug and shakes them back and forth.) You're the best friends anyone could have!"
Ruby: (Muffled groaning) "I can see why your father would want to protect such a delicate flower!"
Nick: (groans) "No kidding!"
Penny: (Releases them, fully back to her happy self.) "Oh, he's very sweet! My father's the one that built me! I'm sure you both would love him!"
Ruby: "Wow. (Giggles.) He built you all by himself?"
Penny: "Well, almost! He had some help from Mr. Ironwood."
Ruby: "The General?! Wait...is that why those soldiers were after you?"
Penny: "They like to protect me, too!"
Ruby: (Scoffs) "They don't think you can protect yourself?"
Penny: "They're not sure if I'm ready yet... One day, it will be my job to save the world, but I still have a lot left to learn. That's why my father let me come to the Vytal Festival. I want to see what it's like in the rest of the world, and test myself in the Tournament."
Ruby: "Penny, what are you talking about? Save the world from what? We're in a time of peace! And besides, we have Nick. He's the Kamen Rider."
Penny: (Confused) "That's not what Mr. Ironwood said..."
Nick: (thought) 'Well, she doesn't know that Iron-Brain is a total, useless idiot, who screws up everything he does, and makes a bad situation worse. It was, basically, his fault that Salem was able to destroy both Vale, and Atlas, as well as get her hands on both the Relics of Creation and Wisdom. I don't even know how he became a general in the first place. I'll ask Ozpin later. Besides, I've been aware that Penny was an Android the whole time, seeing as I was a big fan of the RWBY show.'
Soldier 1: (Off-screen.) "Check down here!"
Penny: (Grabs Ruby by the shoulders) "You have to hide!"
Penny then lifts Ruby above her head effortlessly, while Nick jumps to high ground.
Ruby: (Struggles and screams as she is carried toward the dumpster.) "Penny, wait! What are you doing? You don't have to go with them! We can help you!"
Penny: (Throws Ruby into the trash and lifts the lid so she can still talk.) "It's okay, Ruby. They're not bad people; I just don't want to get you in trouble. Just promise me you won't tell anyone else my secret. Okay?" (Gravely stares at Ruby.)
Ruby: "I promise."
Ruby lowers her head into the garbage as the lid is put down, but she lifts it a little to peek at the scene outside.
Soldier 1: (Off-screen.) "There she is!"
Penny: "Sal-u-tations, officers!"
Soldier 1: "Why were you running? And what happened to the other girl, and the boy?"
Penny: "What girl and boy? I've been by myself all day!" (Hiccups loudly, then smiles.)
Soldier 1: "You shouldn't cause a scene."
Soldier 2: "Are you okay?"
Penny: (Shows off her "injured" palms.) "Just a scratch."
Soldier 1: "Penny, your father isn't going to be happy about this."
Soldier 2: "Please, just come with us."
Penny: "Yes, sir!"
Nick: "Take it easy there, would ya, fellas?"
Nick then jumps down, transformed as Kamen Rider Kuuga, and walks towards Penny and the two soldiers.
Soldier 1: "T-The Kamen Rider?! (stands straight and salutes to Kuuga with other soldier) It's an honor, sir!"
KR Kuuga: "Dudes, chill. You don't need to salute at me, okay?"
Soldier 2: "Apologies, Kamen Rider, sir. It's just an honor to be able to meet the greatest warrior on the planet."
KR Kuuga: "The greatest warrior on the planet, huh? That's a new one. Anyways, take it easy on Penny, alright guys? She was just doing a little sightseeing, that's all."
Soldier 2: "But, we were ordered to keep an eye on her, and now she's injured."
KR Kuuga: "She's fine, she's an Android, she's practically indestructible. And yes, I know she an Android. I've known the whole time. I'm aware of how your boss thinks. Also, she's her own person, she can go around town as much as she wants, okay?"
Soldier 1: "Very well then, sir. But, right now, we should get Penny back."
KR Kuuga: (sighs) "Fine. I'll see ya around, alright Penny?"
Penny: "Of course, Ni-I mean, Mr. Kamen Rider!"
Penny and the soldiers then walk away as Ruby looks on in sadness...until a rat screeches from below her feet, causing the young Huntress to fall and close the lid on herself, as Kuuga then looks at the dumpster. We later see the ruined parts of Vale, the sound of an engine gets closer and closer until a yellow motorcycle called "Bumblebee" pulls into the street and stops, showing Yang behind the handlebars in her matching helmet, while Erza is on a red and black motorcycle, which is called the "Boostriker", which she borrowed from Nick with a Boost Raise Buckle. Yang then takes off her helmet, talking to someone off-screen as she gestures with her thumb to the music playing nearby.
Yang: "Come on, my friend's right in here!"
Yang gets off her bike, to reveal Neptune sitting right behind her, with his hair and goggles messed up with a petrified expression of terror on his face.
Neptune: (Sounding dizzy) "Cool... (Shakes his head, somehow perfectly fixing his appearance, and gets off the cycle, looking around worriedly.) And where exactly is...here?"
Erza gets off the Boostriker, which disappears, and follows them. The music from the Club gets louder once inside to show the owner, who's named Junior, behind the bar adjusting his cuffs as his Henchmen stock the bottles, carry boxes, and otherwise stand around on the dance floor, until...
Henchman 1: (runs inside) "Hurry, close the door - she's coming!"
He and another Henchman proceed to roll the doors shut and keep them closed with their bodies.
Junior: (Walks out from the bar) "What are you two idiots doing?!"
The Henchmen shout incoherently until an explosion knocks them to the ground and forces the doors open, allowing a familiar face to walk in through the smoke.
Yang: "Guess who's back!"
Yang continues to smile and pose as eight guns are pointed in her face with an equal number of angry Henchmen behind them. Though this doesn't faze her, she stops and glares at the recording studio where the track is messing up until the frightened bear-headed DJ takes the needle off the record and retreats back under the table. Erza and Neptune the appear behind Yang as the Henchmen continue hoisting their guns.
Neptune: "Yeah, so could you define "friend" for me?"
Erza: "I'm also confused about this."
Junior: "Stop, stop! Nobody shoot. (Cuts his way through the crowd of goons, straightening his tie.) Blondie, you're here! ...Why?"
Yang: "You still owe me a drink."
Yang then grabs Junior by the arm and drags him to the bar through the hired guns.
Neptune: "Whoa-ho-ho-ho, what a woman..."
Erza: "I would not, Neptune. Yang and I already have a boyfriend."
Neptune: (Breaks from his lovestruck staring to look at Erza, confused) "Don't you mean, you both already have "boyfriends"?"
Erza: "No. Yang and I are both dating the same man, same with both my, and her respective teammates. Me, Yang, Ruby, Blake, Amber, Atalanta and Weiss are all dating Nick."
Neptune: (surprised by hearing this) "That dude's got seven girlfriends? (smirks with an impressed look) That sly fox."
Erza: (walks down the stairs into the club) "Nick isn't a fox. He's a Dragon."
Neptune: "Oh, sorry, my bad. (processes what Erza said) Wait...Nick's a what?"
Meanwhile, Blake's fingers trace three scratch marks on a wall before peeking around its corner and seeing a pair of horned Faunus as they are ushered into a building by a bearded man. She turns to Atalanta and Sun next to her.
Blake: "This is it."
Sun: "You sure?"
Blake glares at him and starts moving towards the entrance while unfastening her bow.
Sun: "Y'know, I'm just gonna take your word for it."
The three walk inside the building to a hallway filled with cases, seeing another man announcing "New recruits, keep to the right!" at the young trio as they follow.
Atalanta: "I do not understand. (Holds out the half-mask in her hand) If they believe what they're doing is right, why hide who they are?"
Blake: "The masks are a symbol. Humanity wanted to make monsters out of us, so the Black Fang chose to don the faces of monsters."
Sun: "Grimm masks...That's kind of dark."
Blake: "So was the guy who started it." (Puts her mask on and walks on.)
Sun: "Always sunshine and rainbows with you..." (Follows her lead.)
The new recruits to the Black Fang are moving in a line to the side of the stage, a mere few dozen compared to the hundreds of white-vested, black-hooded soldiers to their left and up above in the balconies. Blake, Atalanta and Sun look around themselves when they stop, and a fully-masked man with tattoos standing starts speaking before the large sheet emblazoned with the bloody wolf and claw marks.
Black Fang Lieutenant: "Thank you all for coming. For those of you who are joining us for the first time tonight, allow me to introduce a very special comrade of ours! I can assure you, he is the key to obtaining what we have fought for for so long!"
The dark pants and brown shoes step forward before the orange tip of a familiar-looking cane taps on the stage. The camera pans up to reveal none other than Roman, smiling confidently even as the crowd starts protesting.
Roman: (Waving mockingly) "Thank you, thank you! Please, hold your applause!"
Antler Faunus: (Pointing at Roman from her place right in front of Blake, Atalanta and Sun) "What's a human doing here?!"
Roman: "I'm glad you asked, "Deerie"! Now, I'll be the first to admit, humans...are the worst. (Salutes as an example.) Case in point. So, I understand why you would like to see us all locked away, or, better yet, killed!"
Sun: (Leans over to Blake and Atalanta.) "So, is he going somewhere with this?"
Roman: "But, before the claws come out, I'd like to mention the fact that you and I all have a common enemy: the ones in control, the people pulling the strings, the dirty, rotten humans that run our kingdoms! (As the crowd changes their tune and starts agreeing with him.) Government, military, even the schools, heck, even the Kamen Rider himself: they're all to blame for your lot in life! (Lets the crowd cheer as the three heroes share a look.) And they're all pests that need to be dealt with! Fortunately, I'm the best exterminator around...No offense to any rodents in the room."
With a snap of the fingers, the curtain falls, and the whole mass of Faunus applaud at the sight of the Atlesian Paladin-290 behind it, the mark of the Black Fang painted on its shoulder.
Sun: "Whoa, that's a big robot..."
Blake: "How did he get that?"
Roman: "As some of you may have heard, this right here... (Taps the giant mech) ...is Atlas' newest defense against all the scary things in the world. And thanks to my "employer", we've managed to snag a few before they, uh, "hit the shelves". Now, many of your brothers have already moved down to our new operation in the southeast. If you'd rather stay within the city, that's fine... But if you're truly ready to fight for what you believe in, this is the arsenal I can provide you. Any questions? (The Black Fang's roaring applause tells him the answer.)
Blake: (To Atalanta and Sun) "We should get out of here."
Atalanta: "Agreed."
Black Fang Lieutenant: "Will all new recruits, please come forward!"
The line surges forward with Blake, Atalanta and Sun having to follow.
Sun: "Welp!"
Back at the Club, Junior puts down his glass as he sits behind the bar separating him from his interrogator.
Junior: "I don't know!"
Yang: "How can you not know?"
Junior: "I haven't talked to him! I haven't even seen him since the night you first came in here. (Leans over to point in Yang's face.) He paid up front, I lent him my men, and none of them ever. Came. Back."
Neptune then Rushes to Yang's side to raise a question of his own.
Neptune: "So where did they go?"
Junior: (After a long pause) "What kind of stupid question is that? They never came back! (To Yang) Who is this guy?"
Yang: (Pushes Neptune out of the way with one hand.) "Don't worry about him; worry about me (Neptune straightens and stands to attention) if I don't find out what I want!"
Junior: "I already told you everything! Torchwick hired my boys, and I guess he wasn't happy with them, which is something I can relate to!"
He shouts this at his own men, who grumble and walk away in response.
Erza: "And you really don't have any other information? Like, any possible leads that could help us?"
Junior: "Not in the slightest."
Yang: "Come on, Erza, Neptune." (Turns from the bar and walks away.)
Neptune: (Follows with his hands in his pockets.) "We get everything we need?"
Yang: "Well, we got everything we can. Hopefully the rest of the team is having better luck."
Erza: "Indeed."
Back at the Black Fang is still cheering loudly as the recruits are marched to the stage, with Blake, Atalanta and Sun having no choice but to follow along.
Sun: (Whispers to Blake and Atalanta) "What are we going to do?!"
Blake: "I'm thinking..."
Atalanta watches Roman lean on the robot smoking his cigar and laughing before he zeroes in on the two, frowning.
Sun: "He sees us..."
Blake: (Notices the junction box on the wall.) "He can't see in the dark."
With that, Blake unsheathes Gambol Shroud, transforms it into a pistol, and shoots at the box, making the lights go out for the whole building and turning the screen dark.
Roman: "Don't let them get away!"
Blake: "Atalanta! Sun! The window!"
Roman: "Stop them!"
Before the three student Huntsmen crash through the window and start running as fast as they can, the mechanized sound of running power signals the Altesian Paladin's activation, and it crashes through the wall of the building in pursuit of the runaways, who leap off of a car and manage to get on the roofs. The Paladin follows beside them on the street as Blake, Atalanta and Sun run, jump, and flip from rooftop to rooftop.
Sun: (Amidst twirls in the air) "So you wouldn't happen to have...oh, I don't know...some form of backup?!"
Blake: "On it!"
Blake grabs her Scroll and puts it to her ear as she continues to jump. Weiss and Amber are seen leaving the Cross Continental Transmit tower's elevator when they grab their own, respective, Scrolls and listen to Blake's message.
Blake: (Scroll-call) "Everyone! If you can hear me, we need back-"
Sun: (Scroll-call, in the background) "HEEEELLLLP!"
Weiss rolls her eyes, as she and Amber start running out the door, a little smile on Weiss' face as she does so. Nick and Ruby are still beside the dumpster (which is boarded up, possibly to keep the rat imprisoned), staring at their Scrolls.
Sun: (Scroll-call) "Big robot! And it's big! Really big!"
Ruby: (Excitedly) "Oh, we are not missing this!"
Nick: "Agreed. Hang on."
Nick then pulls out a smartphone, which is called the "Build Phone", and then inserts a scarlet bottle with the image of a bike on it into a slot on the Build Phone, before tossing the phone forward.
Build Phone: Build Change!
The Build Phone then grows larger and transforms into a bike, known as the "Machine Builder", as Nick gets on it.
It's actually supposed to be with the Lion Fullbottle, but I decided to use the Bike Fullbottle instead.
Nick: (looks at Ruby) "Well? You coming or what?"
Ruby smiles and gets on the bike behind Nick, as they race off to join the fight. Elsewhere, Yang is back on the motorcycle in her helmet and sunglasses with Neptune looking at the Scroll in her hand over her shoulder, while Erza is back on her own Boostriker.
Sun: (Scroll-call) "That Torchwick guy is in it! But not, like, it didn't eat him; he's, like, controlling it or something!"
Yang: "Where are you guys?"
Right on cue, behind them, Blake, Atalanta and Sun can be seen running through the street with the Paladin hot on their heels before they all disappear from view.
Sun: (In both person and on the Scroll) "HURRYYYY!!!"
Neptune: "I think that was them."
Erza: "Most likely."
Yang: "Yeah, I got it."
Yang puts her Scroll away, then she and Erza quickly circle their rides around - much to Neptune's alarm - and drives off to follow them. Blake, Atalanta and Sun somehow make it to the highways, jumping down into the busy street and continuing their escape by hopping on cars while the Paladin follows them by pushing vehicles out of the way. Sun pauses to look at their pursuer's path of destruction and offer a quick "Whoa!" before leaping onto more cars, much to the anger of Roman inside the robot, his face surrounded by blue holographic screens. Yang, Erza and Neptune are able to follow the mech suit on their rides, coming up next to it as it runs.
Yang: "We've gotta slow it down!"
Erza: "I can't use my Semblance in this situation."
Neptune: "I got it!"
Neptune reaches for his gun, but Roman notices the pair on his sensors and crashes into a multitude of cars with the Paladin's strong bulk, sending them flying towards his chasers.
Yang: "Hold on!"
Neptune: "Wuh-oh..."
Yang and Erza swerve, leaning their bikes to the side in avoidance of flying debris while Neptune flails in a panic. Back on two wheels again, Neptune unslings his weapon, aims as sparks start flying, and fires several bolts of blue electricity at the Paladin, causing Roman to grimace from the force of the attacks. Switching strategies, Neptune flips the gun and it grows a shaft and an energy blade at the end, then jumps from Yang's bike as the spear's head splits in three and drives it into the top of the Paladin. Sun, Blake and Atalanta pause in their car-hopping to look back.
Sun: "Neptune, hang on!"
Neptune is trying his best, but the mech keeps bucking and threatens to make him fall. Closing his eyes, Sun smashes his palms together, and from the golden Aura around him, his Semblance creates two glowing outlines that copy their creator, leaping off and going back over the tops of vehicles to collide into the Paladin's front. They explode into blinding light upon contact to let Sun leap forward with his weapon, Ruyi Bang and Jingu Bang, held high, but Roman finally turns enough to send Neptune flying off and knocking into his leader, sending both of them off the highway. As Blake and Atalanta look on from their spot, they hears a voice from Blake's Scroll:
Weiss: (Scroll-call) "Blake! I'm in position!"
Weiss and Amber are seen twirling over a highway and landing in the middle of the road, with Weiss holding Myrtenaster at the approaching Roman. He smiles as his robot charges the girls, but Weiss spins and plunges her blade into the ground, summoning a circle of ice across the pavement, with Amber also creating ice as well through her Magic, that causes the Paladin to slip and crash, actually flying over the two young Huntresses and falling off the ramp, landing further down before Ruby, already having her Crescent Rose out in scythe form, and Nick, who is transformed as Kamen Rider Build SharkBike form. The Paladin stands back up, and the rest of Teams RWBY (Ruby) and NAAE (Unimaginable) fall beside their leaders to take up positions. Roman chuckles, moving the robot slowly towards the group.
KR Build: (to Team RWBY (Ruby).) "You girls can handle this one. We'll sit this one out."
Ruby: "Freezer Burn!"
Ruby and Blake jump back out of the way as Weiss performs her same ice-circle trick, but backs out of Yang's way when she jumps into the air and hits the epicenter with her Ember Celica, creating a wave of mist that surrounds Roman. Immediately, the Paladin activates its laser sensors to make up for the lost sight, but it barely sees the afterimage of Blake and narrowly misses the dashing Yang. A gun manages to fire at the area between Blake and Yang, but out from the blast comes Ruby, who slashes the metal with her blade, causing it to falter.
Ruby: "Checkmate!"
Blake and Weiss go in this time, each girl going for the feet until Weiss jumps up and stabs a sensor before leaping off of a white glyph. Roman lifts the Paladin's foot to crush Blake, but Weiss summons another glyph under her teammate to launch her backwards before the crushing blow can land. Roman growls and fires off the missiles, but Weiss and Blake flip backwards as the explosions merely hit where they were. Finally, Weiss jumps up too high, and Roman fires a double energy blast at her. Myrtenaster absorbs the damage, but Weiss is thrown back, so she casts a beam of light from her weapon to the ground under Blake, forming a yellow clockwork circle that's absorbed into the Faunus girl and lets her slice through each launched missile with ease in a flurry of super-fast slashes.
Ruby: (Runs into the fray) "Ladybug!"
Ruby shoots herself forward and cuts at the robot's legs, then turns as Blake aims herself at the giant's feet as well. They both dash forward and attack at the same time, circling each other around the Paladin with each strike until they both launch themselves into the air and come down together on the shoulder, cutting off the left arm entirely. Yang doesn't waste a second, jumping onto the Paladin's back and punching the top with fiery shotgun blasts. Roman is knocked around in the cabin, but seeing as he can't reach her with his remaining mechanical arm, he runs backwards through two columns and leaves her embedded in a third before backing away and turning towards her. Just as she is falling down, the remaining arm extends a closed fist, and when it punches her, she flies through the column and doesn't get up.
Blake: "Yang!"
Ruby: "Don't worry! With each hit she gets stronger, and she uses that energy to fight back! That's what makes her special."
Yang slowly gets back on her feet, hair burning a brilliant white as she clenches her fists. Sensing victory, Roman throws a punch, but Yang catches it in her own hand (despite the ground cracking beneath her) and, eyes red with rage, smashes her knuckles into the second arm, obliterating it under her force. Getting desperate with his armless robot, Roman immediately kicks Yang to the side, but as she passes her sister and teammates...
Ruby: "Bumblebee!"
Blake throws her Gambol Shroud out for Yang to catch while flying, and the Faunus uses the momentum to swing the glowing girl around for a final hit to the robot. Roman, however, steps out of the way just in time to avoid complete destruction.
Ruby: "We have to slow it down!"
Weiss: "And how do you propose we do that?"
Ruby: "Ice Flower!"
Twirling their weapons so they both point at Roman, Weiss creates a series of glyphs in front of the scythe's sniper barrel, and a single shot through the circles creates a dazzling spiral of energy that creates large icicles upon impact with the Paladin. Ruby continues to shoot as Weiss freezes the fire, and as the ice completely envelops the robot's body, Blake swings her partner around in a circle one more time, but with Roman unable to move, the Paladin is hit by the speed and power of Yang's fists, flying into the air before crashing down in a hundred pieces and a defeated criminal.
Roman: (Gets up, slightly dazed but unharmed, as he inspects the damage while brushing himself off) "Just got this thing cleaned..."
He looks up just in time to see Yang, still burning with her absorbed power, fire a single shot at the defenseless thief, but he's saved at the last instant when a mysterious wall made out of shadows is seen emerging in front of him and deflects the blast entirely.
Roman: "Kamen Rider, Ladies, Ice Queen..."
Weiss: "Hey!"
Roman: "Always a pleasure! And, until next time..."
Yang will have none of it, charging forth with fists raised to strike the outlaw...only for Roman to be engulfed by shadows...vanishing completely. The rest of Team RWBY (Ruby), along with Team NAAE (Unimaginable), runs up to Yang's side, with her now cooled down with the end of the fight.
Yang: "So...that just happened..."
Nick: (de-transforms) "Yeah...that wasn't suppose to happen. I have no idea what that was."
Amber: "I take it that we head home then?"
Nick: "Might as well."
Ruby: "Wait...where are Sun and Neptune?"
Nick: "Don't worry about them. They're fine."
As Nick had said, Sun and Neptune are sitting in the middle stools of the "A Simple Wok Noodle House" eating their plates of noodles with the Shopkeep behind the counter and their weapons leaning on the other two stools.
Neptune: "They're probably fine, right?"
Sun: "Totally. The Kamen Rider's there with them, after all."
Neptune nods and turns back to his noodles, as the two eat in silence until the screen cuts to black.
