(In Atlas, a blonde man is seen preparing to attack the Schnee Dust Company.)

????: Those bastards have treated the poor faunus badly for too long. I won't tolerate this any longer.

TWO SIDRIVER!

BAT!

CONFIRMED!

EENIE MEENIE MINIE MOE! EENIE MEENIE MINIE MOE!

????: HENSHIN!

VERSUS UP! PRECIOUS! TRUST US! JUSTICE! BAT! KAMEN RIDER LIVE!

Live: Let's settle this seriously!

(Then Kamen Rider Live attacks the Schnee Dust Company and starts shooting some Atlas Soldiers. One of them tries to contact Ironwood.)

Atlas Soldier: This is Red Team! We're under attack! I repeat, we're under attack! We're under attack by a Kamen Rider. He just appeared out of nowhere and...

(Live shoots the Atlas Soldier down, and then Blue the Velociraptor comes in alongside Knuckles, Owen, the Chaotix and Pegasus Seiya.)

Owen: Remember, take out the front defenses so our brethren can enter the mine.

Knuckles: (cracks his knuckles) Got it.

(Knuckles joins Live, and both kill more Atlas Soldiers while Ray sees some bullheads.)

Ray: Knuckles, I found the Atlas and the Schnee bullheads.

Knuckles: Alright, tell Jet Jaguar to destroy them all. We're not taking prisoners.

Ray: Roger.

(Then Jet Jaguar comes in and destroys all of the Atlas and Schnee bullheads. Then the Big Hero 6 come in, and Honey Lemon throws some explosives which blow the Atlas troops away.)

Hiro: Remember, friends. This is a rescue mission.

(Timeskip)

(Live, Knuckles, Blue and the other heroes resume their mission, but suddenly a voice is heard.)

Atlas Soldier: Stay back, scums!

(Then an Atlas Soldier is seen holding a gun at a young child's head while all other Atlas Soldiers aim their weapons at the other faunus and powerless.)

Atlas Soldier: Lay down your weapons and surrender, or this worthless, powerless child pays the price.

????: Are you sure about that?

(They turn around to see Kunio Hino, who inserts three core medals in his driver before scanning them.)

Kunio: Henshin!

SHACHI! UNAGI! TAKO! SHA-SHA-SHAUTA. SHA-SHA-SHAUTA!

(Kunio becomes Kamen Rider OOO, much for the Altas Soldiers' surprise.)

Atlas Soldier: So you're...

(OOO uses his Denkiunagi whips to electrocute the Atlas Soldier, and then Live shoots him, killing him.)

OOO: Are you okay, child?

Child: Yes sir, who are you?

OOO: I am Kamen Rider OOO. I am here to help you and these people.

Child: Really?

OOO: Yes.

(Then Ankh comes in.)

OOO: Ankh, guide this child and the others to the exit.

Ankh: Got it.

(Ankh guides the faunus and powerless people to the exit.)

Atlas Soldier: Open Fire!

(The Atlas troops start shooting, but someone shields the heroes. It's Scarlet Witch using her powers. Blue charges at the soldiers and shoves them away. The Batmobile comes in and Batman (who is inside of it) clicks a button, and the vehicle fires two missiles, and they hit the Atlas troops, blowing them away.)

OOO: Call the Justice League, and tell them to take the faunus and powerless people somewhere safe.

Batman: They're already coming in the meeting place.

Blue: (roars)

Atlas Soldier: KILL THEM! KILL THEM ALL!

S. Witch: Focus on me, bastards!

(Scarlet Witch uses her telekinesis to rip all of the remaining Atlas troops apart.)

OOO: Time to go!

(The heroes walk out of the mine, and both Justice League and Avengers are seen guiding the faunus and the powerless people to the quinjet.)

Ankh: Kunio, the Union Heroes are on their way.

Jack: (comes in) What's the plan for them?

OOO: Shiro, call X!

Shiro: Right.

X: Let's unite.

(Then Shiro prepares to transform.)

NOW UNITING WITH ULTRAMAN X!

Shiro: X!

X, UNITED!

(Then Shiro becomes Ultraman X, and sees three bullheads.)

X: It's them.

(Inside the bullheads are Team RWBY, Bakusquad and Ironwood, who see Ultraman X.)

Ruby: (scared) AAAAAAH! GIANT! GIANT! GIANT! GIANT!

Ironwood: Calm down, we'll take him down.

(Ironwood clicks a button, and a missile is about to be fired.)

Ironwood: FIRE!

(The missile is fired, but Ultraman X catches it and crushes it.)

Eijiro: What the...

(Suddenly someone slashes the three bullheads at the same time. It's Samurai Jack. The Union Heroes jump off and land in a forest, where they see Kamen Rider OOO.)

OOO: So? A crazy day, isn't it?

Bakugo: YOU WON'T STOP US, YOU FUCKING EXTRA!

OOO: Try me!

(Bakugo tries to blast OOO, who simply turns his body into liquid, and gets unfazed by his attack.)

OOO: Is that your best?

(Mina spits some acid at OOO, who dodges them, and then he easily knocks Mina out.)

Eijiro: PINKY!

Denki: I'll make you pay!

(Denki tries to electrocute OOO, but he takes it like it's nothing.)

OOO: You call this shocking? Let me show you SHOCKING!

(Then OOO swings his Denkiunagi whips at Denki, and electrocutes him.)

OOO: Next?

(Ruby charges quickly and swings her Crescent Rose at OOO, who liquifies his body again.)

Ruby: What?

Weiss: Ruby, dodge!

(Weiss shoots some ice dust from her Myrtenaster, but then an electric force field blocks the attack. OOO turns to see Static Shock.)

Static: I'll put a shock to your system!

(Ruby and Weiss try to shoot Static Shock, who dodges the bullets and brings them down with a powerful shockwave. Bakugo charges at OOO and punches him repeatedly, but the Rider is unfazed.)

Bakugo: (angry) Why won't you DIE?

(OOO simply kicks him away and prepares to finish him.)

SCANNING CHARGE!

(OOO liquefies his lower body to propel himself upward, then use the Unagi Whips to drag Bakugo upward while OOO goes back down using the Octo Legs to perform a corkscrew kick that drills through him.)

OOO: SEIYA!

(Bakugo screams in pain.)

Bakugo: NOOOO. I WAS SUPPOSED TO BE THE NUMBER ONE HERO. AAAAAAARGH!

(Bakugo explodes, dying. Static Shock electrocute Sero and Blake. Only Yang is remaining. She runs at OOO, but doesn't attack him, much for Static's confusion.)

Yang: You're a strong guy, I must admit.

OOO: And you're a smart girl for not trying to attack me.

Yang: That's funny. Somehow I remember you...

OOO: We used to be friends in childhood before that incident. Does that ring a bell?

Yang: Kunio...

Mina: (gets up) Kunio? Is that really you?

OOO: Hi, Mina.

Mina: Look, I'm really sorry for what happened to your sister in the past... and even more I wasn't there to comfort you...

OOO: There was nothing we could do. We were just kids...

Yang: You have a yanging point. But now we have grown up.

OOO: I hope we meet again... under different circumstances...

Yang/Mina: So do we.

(Then OOO nods at Static Shock, and both leave as Yang and Mina smile.)

(Meanwhile Ultraman X is seen hitting a mech piloted by Ironwood himself. But then it dashes at him, and knocks him down. X gets up, only to be kicked from behind, and falls down. Ironwood's Mecha starts shooting Ultraman X.)

Ironwood: Don't fuck with this general!

(Before Ironwood can finish Ultraman X, Vulcan comes in and prepares to shoot his Mecha.)

BULLET! SHOOTING BLAST!

(Vulcan shoots at the mech, bringing it down.)

Ironwood: What the...

(Inside Ultraman X, Shiro receives a card.)

Shiro: Another card...

X: Shiro, are you...

Shiro: It's the only way.

CYBER BEMSTAR, NOW LOADING!

(Then Ultraman X gets the Cyber Bemstar armor parts.)

CYBER BEMSTAR ARMOR, ACTIVE!

(Ultraman X quickly gets up as his current status form is seen.)

X: Let's go, Shiro!

(Ironwood gets shocked by hearing that name, but then Ultraman X throws his Cyber Bemstar Arm Shield at the mech, cutting its head off, and bringing it down. Ironwood is forced to leave the mech as it explodes. The Guardians of Life surround him.)

Ironwood: You haven't won, Guardians of Life! The Ace Operatives are going towards the location of the Alien.

(The heroes get shocked that the Ace Operatives are after Broly.)

Ironwood: This will be the end of the Guardians of Life!
