We see Team JNPR (Juniper) readying themselves against their opponents in the Amity Colosseum, the mountains to their back and forest on the other side. A large holographic screen counts down with Port over the crowd's cheering.
Port: "3...2...1..."
Jaune: (raising his sword) Come on guys!
Port: "BEGIN!"
All four members of JNPR (Juniper) charge forward, but only three fighters from BRNZ (Bronze) do the same; the beanie-wearing May Zedong turns around and heads into the trees, cocking her weapon. In the center of the field, leader Brawnz Ni delivers a knee kick to Pyrrha's shield that sends her skidding back, right before she blocks the claws on his fists with her xiphos. She jerks her sword away and makes him leap back, just as the sniper jumps up into the branches of the forest with the bladed butt of her sniper rifle. Ren readies his StormFlower to attack Nolan Porfirio, who almost gets blindsided by Nora's swing with Magnhild before he ducks under the attack and attempts to hit her with his cattle prod. The sniper girl finally takes aim from her spot and manages to fire off two rounds near Ren, destroying the rocks behind him. Jaune manages to block the buzzsaw gloves of Roy Stallion with his own shield before he notices the bullets flying and sees the glint of the gun in the leaves.
Jaune: "Fall back! Nora, give us some cover fire!"
Ren glances back at his leader as a shot hits the ground by his feet. He and Nora, who is firing grenades at the enemy team, start running back into the mountains as Jaune and Pyrrha cover their escape by blocking the bullets with their shields. The four leap over a rocky outcropping for cover.
Pyrrha: (to Jaune as projectiles keep coming overhead) "What do we do?"
Jaune: (looks over the edge to see the melee fighters closing in) "Spread out! Try to keep moving!"
His team follows this just as Brawnz lands a punch on Jaune's shield. May gets even higher in the tree and smiles from behind her scope as she looks at the fight below. Brawnz and Pyrrha continue to duke it out while Nolan slowly advances on Ren when he slides into his path. The prod-wielding warrior looks back at the trees and nods to his hidden ally, who shoots at Ren's feet again and makes him jump around trying to dodge them. Just as he lands, Nolan hits him upside the head with his weapon and is able to easily dodge the retaliatory kick while landing another blow to Ren's knee and a final hit to the chest using the business end of his prod. Electricity shoots through Ren's body before he collapses to the ground beside his childhood friend.
Nora: "Ren!"
Scowling, Nora takes a swing at Nolan, who promptly dodges it and again unleashes his weapon's power into her corset, though this causes a quite different reaction from the grinning redhead.
Port: (speaking from his spot on the giant hologram screen overhead with Doctor Oobleck beside him) "Oh-ho! Looks like one of my favorite students, Nora Valkyrie, is charging up to use her Semblance!"
Nolan: (looking up at the screen with a panicked look) "What?"
Oobleck: "Yes, Ms. Valkyrie's Semblance lets her produce, as well as channel, electrical energy straight to her muscles! This allows her to jump explosively into the air, wield her mighty hammer, or in this case, absorb Nolan's attacks and send the young man flying!"
Nolan: (turning back to his opponent) "What?!"
Nolan finally takes his cattle prod away, but the damage is done: Nora flexes her arms as pink lightning is seen coursing through her body. Nolan attempts to lift his hands up in surrender, but thunder starts sparking from Nora's Aura as she rushes at him. There's a split-second where Nolan's horrified face and Nora's victorious smile are seen close-up on the sides of the screens before the hammer hits head-on and Nolan bounces back across the field, crashing through a rock and staying there when he's stopped moving. Jaune looks back at the mountaintop on his team's side as a dark storm cloud appears over it, crackling with lightning. He looks over at his energized teammate.
Jaune: "Nora! Get to the mountain!"
Nora: (saluting) "You got it!"
She sprints off to start her climb.
Jaune: "Ren! Try and distract the sniper!"
Ren: (as another shot nearly misses his head, he slouches, sarcastically replying) "Sure...Why not."
The remaining three members of JNPR (Juniper) run forward as Nora hops up and rapidly ascends the mountain. Roy throws the saws from his gloves into Jaune's shield, which still manages to bend the metal and slam the leader's own defense in his face before the weapons return back to their master. Pyrrha gets up close to him, and he delivers a series of spinning swings with his arms into Akoúo̱ as Jaune shakes off his disorientation and charges into battle yet again.
Ruby: (from her seat in the stands with the rest of Team RWBY (Ruby) and Team NAAE (Unimaginable).) "Yeah! Go get 'em, Jaune!"
Weiss: "Well, he's certainly improved."
Nick: "Yeah well, I did help him train for a while, remember?"
Yang: "Yeah, but he ain't got nothing on Pyrrha, or Nick!"
Back in the fight, Yang's statement is proven true with Pyrrha taking on both Brawnz and Roy, delivering a kick to one as she deftly dodges and blocks the discs of the other, throwing her javelin to distract the latter while she somersaults back to use both feet in landing a blow on Brawnz. May attempts to shoot Ren while he dashes his way toward her position, leaping out of the way of her shots, the flying saws, and even sliding under Pyrrha before he runs at Nolan, weapons blasting until he's close enough to start swinging his blades away. He ducks and deflects each of the cattle prod's attempted hits until he manages to hold it in the pistol's blades and double kicks his opponent, giving him the opportunity to catch Nolan's weapon in his own as the prod is forced behind Nolan's head and leaves him trapped. Ren hides behind the teammate of the sniper, who stops aiming at him and lifts her barrel up to another target.
Ren: (as he keeps the struggling Nolan in place) "Nora!"
Jaune then catches Brawnz's claws with his blade while Nora lifts herself higher and higher to the top.
Jaune: "Pyrrha! Up!"
His partner rushes towards him, dodge rolling to avoid a launched saw until she bounds over Brawnz and lands on Jaune's shield. He manages to throw her into the air with her own shield raised to block the kill-shot aimed at Nora. This gives the redhead just enough time reach the peak, and she lifts her hammer up as a bolt of lightning hits the weapon directly. She changes it back into grenade-launching form and pops the front off to reveal six explosives that shoot out over the field in a heart-shaped formation onto the sniper. The poor girl barely has time to gawk before she leaps over to a nearby tree just as the one she was in goes up in pink flames, leaving only a giant scorch mark billowing smoke to block out the coughing sniper's view. She jumps down from the branches just as her three teammates look up and behind them at Nora coming down on them like a meteor, slamming her hammer into the ground and sending the enemies back at the feet of their disoriented teammate. Before anyone can react, Nora jumps over in front of Team BRNZ (Bronze), then brings her hammer around to collide with all four screaming fighters as they soar straight into the forcefield surrounding the arena's rim, sliding down to the ground with arms and legs in bent positions they really shouldn't be.
Port: "And with that, it appears Team JNPR (Juniper) wins by knockout, literally!...Can someone go make sure they're okay?"
At the appropriately-named Crow Bar, a gray-haired figure in a tattered red cloak is sitting at the counter with a collection of empty glasses to his side. He takes a swig from another drink as he looks up at the screen above, displaying an image of the victors with the caption "Team JNPR (Juniper) Defeats Team BRNZ (Bronze)!"
Bartender: (as he wipes the surface of a glass in his hands) "Huh, those kids weren't half bad!"
The familiar stranger merely lets out a "Meh" as he raises the beverage back to his lips. The scene flashes to a blue background with white particles gathering into the united tournament symbol of the four kingdoms as it revolves to the left of Oobleck, back in the announcer's box.
Oobleck: (with an image of Team BRNZ (Bronze) at the moment they all felt the force of Nora's hammer) "Ah, well, Vacuo fans are sure to be hurting after that one, but this next one will have them on the edge of their seats!"
Port: (displaying a picture of the four new challengers to his right) "Team NDGO (Indigo) of Shade is certainly a crowd favorite, but these lovely ladies are going against some of the toughest, testosterone-filled teammates we've seen so far! I'm of course talking about...Team NAAE (Unimaginable)! Nick Brown and his team are certainly a force to be reckoned with, and although he'll be representing the Vale Academy of Beacon, I'm sure his family back in Mistral will be cheering him along!"
I know it was supposed to be Team SSSN (Sun) who fought against Team NDGO (Indigo), but they aren't really important characters in the show if you ask me.
Oobleck: "And quite the challenge Team NDGO (Indigo) have in this match. As Nick Brown is actually non other then the Kamen Rider himself!"
Team NAAE (Unimaginable) walks into the center of the field, waving to the cheering crowds, who are all also shocked by the revaluation of Nick being the Kamen Rider, as they do so.
Ruby: "Go Team NAAE (Unimaginable)!"
Weiss: "I wonder what Nick will turn into this time."
The holographic roulette shows up again, landing on a yellow image of sunny dunes and stone formations until the real thing emerges from below. A small circular light even appears overhead, causing most of the crowd to don sunglasses.
Nebula: (laughing as she looks back at their selection) "Alright! Home field advantage!"
Octavia: "Better then no advantage. We'll definitely need it if we're fighting the Kamen Rider of all people."
Atalanta: (looking down at her attire as the roulette begins again on the other side) "I hope I don't get sand in my shoes."
Nick: (leaning over and whispering) "It'll be fine, alright Ata?"
Dew: (when the spinning images stop on a blue symbol of tidal waves) "Hey! The ocean!"
Nick: "Huh? (Turns and sees the random pick for himself) I can work with that."
Port: "Now, before we begin the match, let us allow Nick Brown to have the moment to transform."
Oobleck: "I wonder what he will transform into for this match."
Nick then pulls off the ring from his right index finger, as a golden hand-shaped gauntlet with a blue translucent blade appears on his right-hand.
Gauntlet: TegaSword Morpher!
Yang: "It's a gauntlet?"
Weiss: "Why does it look like a right-hand?"
Nick: (lightly blows on the ring) "Engage!"
RWBY, AAE, and JNPR: "He didn't say "Kamen Rider"?"
Nick then inserts the Ring into the slot below the TegaSword's blade.
TegaSword: Clap your hands!
Nick then swings the TegaSword to his left, holding it vertically by his head and clapping twice. He then moves his feet, placing the left foot in front at a 90° angle and the right foot behind at a 180° angle clockwise. Nick's changing of foot positions is done simultaneously while swinging the TegaSword to his right, holding it vertically on the opposite side of his head and clapping once. Nick then swings the TegaSword in a circular motion 360° clockwise once and another 270° clockwise from his point of view, drawing a wide and pointing the TegaSword horizontally to his left while holding it by his hip, clapping twice. The circulation motion results in a red energy ring to manifest in front of Nick. Nick then twirls 360° to his right while pointing the TegaSword upwards, drawing and manifesting a gold-colored energy ring to manifest above him. Nick then holds the TegaSword above his head, clapping once. The red energy ring becomes a chest piece, while the gold-colored energy ring becomes a helmet that looks like Nick's ring.
TegaSword: (Whoa-oa-oa-oa) GozyuWolf! (Whoa-oa-oa-oa)
Nick was now transformed into the 50th Red Ranger: GozyuWolf, as he then howls into the sky, releasing a red sonic wave.
Ruby: (sparkle eyed in amazement of Nick's latest transformation) "He's a red warrior! He looks awesome!"
Blake: (conflicted) "I don't know how I feel about our boyfriend being a wolf-themed hero."
Yang: "I feel like we've seen that suit somewhere before."
Ruby: "He's GozyuWolf! From No.1 Sentai Gozyugers. We've watched a few episodes of Power Rangers with Nick a while ago. Plus, he gave us a few Super Sentai/Power Ranger lessons."
GozyuWolf: "Alright! I'm good and ready to go!"
Team NDGO (Indigo): (thought) 'We're so gonna lose...'
Oobleck: "3, 2, 1, BEGIN!"
As soon as the word is said, Nebula calls out her first order.
Nebula: "Open fire!"
Team NDGO (Indigo) goes forward into their turf as Team NAAE (Unimaginable) follows them, Erza with her sword raised, she comes upon Octavia emerging out from a nearby arch and tries to slice her with her sword. Octavia ducks under the swing and continues sliding away, past the middle of Dew and Amber getting ready to rumble. Amber hefts her staff overhead with both hands and brings it down, only to get knocked back by Dew's spear. Amber glances up in time to see the blonde wave her weapon over the sand to create three small twisters that kick up dust in Amber's face. She looks around as they surround her, but doesn't realize the danger until they coalesce into one big tornado that picks him up off the ground. Amber then uses her Magic to create a stronger tornado of her own that overpowers the first tornado, and blows Dew out of the arena.
Oobleck: (as Dew slams the ground with fists upon seeing her image now crossed out on the holographic board) "And NAAE (Unimaginable) gains the advantage!"
Octavia slides in front of GozyuWolf and Atalanta, who ready themselves to fight her just as she spins her sword around and produces a wave of flame that kicks up dust in their faces. The two manage to jump out of the cloud thanks to their enhanced speeds.
Time Skip because I'm not feeling like typing this whole thing...
We see that Dew manages to get back up as Nebula and Gwen join their comrade, lifting their weapons and ready to fight once more. GozyuWolf then stand near the shore of the water area, as he then howls at the water, with a red mechanical orca jumping out of the water.
Orca: OrcaBooster! 5050~!
The OrcaBooster5050 then shrinks to the size of a handgun, as GozyuWolf then catches it, gaining a small surge of power from the OrcaBooster, before then activating the finisher.
OrcaBooster5050: Orca! Boosted Nova!
GozyuWolf then creates water around him, which summons water tunnels that captures and smacks around the remaining members of NDGO (Indigo) are around him, as they are now laying on the ground defeated with the sound of the buzzer.
Port: (while Team NAAE (Unimaginable) all high-five each other in celebration) "And with that, Team NAAE (Unimaginable) moves on to the doubles round! (to Oobleck) You know what I call that victory?"
Oobleck: "Unimaginable?"
Port: "No, spectacular, as not even one member of their team was defeated. What just you said is stupid."
Oobleck turns away, frowning. Clearly upset that Port didn't get his joke.
Bartender: (whistling at the screen, back in his establishment with its one customer) "Now that was a match!"
Customer: (a light slur in his words) "Heh, that was a mess!" (thought) 'I can't believe that was really the Kamen Rider...why the heck is he a student?'
Bartender: "Come on man, you didn't like them, even one of them is the Kamen Rider himself, the Vale kids, or any of the rounds before that? What fight are you here for?"
Customer: (sees an aircraft with elegant ribbons flying from its wings behind him) "That one."
He then finishes his drink as the world sways with the happily inebriated Huntsman until he slams the glass down on the counter and tosses a few Lien alongside it.
Customer: "Happy Vytal Festival!"
The bartender watches as his sole patron staggers away and puts down the glass he just finished cleaning, only to knock it down and shatter it when he reaches for another one.
Bartender: "Aw, gee darn it!"
Ruby: (leans back in her seat and sighs) "Aw, that was so awesome!"
Yang: Looks like the others made it to the next round!
Blake: "I still don't know how I feel about Nick being a wolf-themed hero."
Oobleck: (over the sound system) "That concludes the matches for today. Please leave the Coliseum IN A CALM AND ORDERLY FASHION!"
Yang: (after Team RWBY (Ruby) stops flinching from the unexpected volume change) "Come on, let's go congratulate 'em."
The four girls get up from their seats and start to head out just as the same ribbon-adorned craft passes over the Colosseum, causing Weiss to stop in her tracks and Ruby to bounce into her.
Ruby: "Uh, what are you viewing?"
Weiss: (looking up at the craft with a strange expression and strain in her voice) "She's here!"
The Schnee heiress' face displays a mix of joy and anxiety as the screen cuts to black.
