(In Bellwood, Bat 10 and the Hyperdimension Network Heroes are seen heading towards the city as the mayor is evacuating people.)

Mayor: Okay, the citizens are evacuating far away from this battle against the Union Fake Heroes. 

Bat 10: Don't worry, we're gonna rebuild the city and make those fake heroes pay.

Mayor: Good thing you heroes actually care for the world.

Bat 10: Okay, go to Metropolis. Your citizens will be safe.

Mayor: Be careful as well, Mr. Wayne. 

Bat 10: I will.

(Then the mayor evacuates the citizens while Bat 10 turns to his teammates.)

Bat 10: No matter what, we will fight those Union Villains and show them what true heroes are made of.

Heroes: Yeah! Let's crumble! Time to take them down.

(Suddenly a building is seen crumbling, and the heroes turn to see Vilgax.)

Wasabi: Uh… what is that?

O. Prime: I don't know, but I don't think it's Union. 

V2: Indeed it's not him.

K. Knight: It's… Vilgax.

(Vilgax turns to the heroes and sees Bat 10.)

Vilgax: Found you!

Eradicator: Who is this alien?

Wolverine: This is Ben's old archenemy Vilgax.

Vilgax: Indeed. And I am here to reclaim the Omnitrix once and for all.

Bat 10: Not at my watch.

Vilgax: So you're its current wielder…

Bat 10: Yeah, and I'm ready to fight you.

Vilgax: You will die.

(Vilgax punches Bat 10, and then a portal opens up, revealing Arachno-Terror, Skulleton, Inferior, Ryugon, Slasher and Wildfire.)

Vilgax: Who are you?

Arachno-Terror: I am Arachno-Terror, Tarantula Kaiju and ally of Killbus.

Skulleton: I'm Skulleton, dark Samurai skeleton and ally of Kamen Rider Fifteen. 

Inferior: I'm Inferior, the flame kaiju and ally of Kamen Rider Core.

Ryugon: I'm Ryugon, the Dark Mirror Dragon and ally of Kamen Rider Ryuga.

Slasher: I'm Slasher, the ant-mantis kaiju and ally of Kamen Rider Delta. 

Wildfire: And I am Wildfire, the fiery phoenix kaiju and ally of Kamen Rider Falchion.

Darkaiju Riders: And we are Darkaiju Riders. 

Vlad: Oh no, they're after us, Timer.

Timer: Heroes, you know what to do.

ZO: Let's take them all down!

Heroes: Yeah!

(Then they charge at the villains. Wolverine, Rachel, Krypto Knight, Kamen Rider Zero-One and Superman (Jon Tennyson) tackle Vilgax, punching and kicking him. The villain blocks the attacks, grab both Rachel and Riley, throws them at Wolverine and turns to Jonathan.)

Vilgax: You have changed nothing!

Superman: At least I'm a better Superman than that pathetic excuse of a father I had.

Vilgax: Oh yeah, I saw that another one who's much like this world's Kal-El. I bet he won't mind if I take your life.

Superman: Try your luck.

(Vilgax grabs Jon and throws him to a building. Then he sees Zero-One about to kick him, and grabs his leg.)

Zero-One: It was obvious this wouldn't work.

Vilgax: Why did you try then!

Zero-One: This is what heroes do.

Vilgax: Always the same excuse…

Zero-One: And what are you gonna…

(Vilgax slams Zero-One down and steps on him.)

Zero-One: (weakly) Damnit…

Vilgax: Idiot. 

(Meanwhile with the Darkaiju Riders.)

Slasher: Powers of Kamen Rider Delta. 

Wildfire: Powers of Kamen Rider Falchion. 

Arachno-Terror: Powers of Kamen Rider Killbus.

Skulleton: Powers of Kamen Rider Fifteen.

Inferior: Powers of Kamen Rider Core.

Ryugon: Powers of Kamen Rider Ryuga.

Darkaiju Riders: COMMENCE!

(Then they power up.)

Slasher: I'll handle the Amazon wannabe and her allies.

(Then Donna, Carrie, Terry, Vulcan, Zachary and Ultraman charge at Slasher, who blasts them away, but Donna dodges and tries to slash him, but he grabs her sword, throws it away and smacks her away.)

Slasher: You're nothing like Diana.

(Meanwhile Captain Luthor and Daniel charge at Wildfire, who grabs Ryder's hammer and glares at him.)

Wildfire: So you're Ryder.

C. Luthor: Yeah, I'm the leader of the mighty pups.

Wildfire: You can't do anything, and neither will they.

(Wildfire throws Captain Luthor towards the building and does the same with Daniel.)

(Arachno-Terror sees Batgirl, Kaede, Okinawa, Shigen and Kagami charging at him Batgirl uses her gadgets at him, but they don't faze him and he spits a web at her, trapping her before kicking Okina and throwing him to Shigen.)

Arachno-Terror: You're just an old man, nothing more.

(Kagami is seen charging at him, only to be grabbed and thrown to the building.)

Kagami: Ugh, I hate that…

(Skulleton is seen easily defeating the Secret Warriors, and then someone shoots him from behind. It's Captain Marvel.)

C. Marvel: Okay, skeleton freak. Time to send you back to the grave.

Skulleton: Oh yeah? Then take this!

(Skulleton tries to slash Captain Marvel, who dodges his attack, and then charges at him, only to be shoved towards the buildings. She gets up.)

C. Marvel: Okay, it wasn't obviously a good plan.

(Meanwhile Inferior is seen facing the Power Rangers Dino Super Charge.)

D. C. Red Ranger: Let's rumble this kaiju.

D. C. Black Ranger: Time to take him down. 

D. C. Blue Ranger: Time to be taken down, kaiju.

(They charge at Inferior, who scoffs and charges at them as well. He grabs the Red Ranger and throws him to the Black Ranger, and then he hits the Blue Ranger with a flaming blast which sends him into the buildings. Then he tailwhips the Green Ranger and punches the Pink Ranger to the buildings.)

D. C. Gold Ranger: (gasps) Guys.

(Meanwhile Ryugon blasts Kamen Rider Double's teammates, and then he sees Sonic the Hedgehog.)

Ryugon: Say it.

Sonic: What?

Ryugon: Say that I'll never get your power!

Sonic: Hmph. You'll never get my power!

(Sonic charges at Ryugon, who easily blocks his attack.)

Ryugon: Do I look like I need your power?

(Then Ryugon slams Sonic down.)

Ryugon: Such a shame you choose to protect the humans.

(Back to Vilgax, he is seen shooting some bombs which bring down Scarlet Witch, Generator Rex and Drew Saturday. Suddenly a fireball hits Vilgax, who sees Blaze the Cat.)

Vilgax: Grrr… so the princess thinks she can destroy me?

(Then Vilgax punches her away, and she crashes into the wall. Then she whimpers as she sees Vilgax walking towards her until Kamen Rider Double, Rogue, Fighter Roar and Shadowcat come to rescue her.)

Double: Leave her alone.

(Then they kicked him away, and he sees Mega Man.EXE and his team charging at him, and then Ryugon decides to interfere.)

Ryugon: ENOUGH!

Wristdriver: Advent!

(Then a black dragon emerges and blocks the heroes. Having no other choice, Timer and Vlad decide to take action.)

Timer: Powers of Kamen Rider Zi-O. 

Vlad: Powers of Kamen Kiva.

Timer/Vlad: COMMENCE!

(Then they power up, catching the Darkaiju Riders' attention.)

Slasher: (smirks) So you decided to fight.

Timer: You ain't gonna take me alive, villains!

Wildfire: Let's see you handle THIS!

WristDriver: Battou! Eternal Phoenix!

Timer: Really?

Wrister: Finish Time! Time Break!

(Then Timer manages to destroy Wildfire.)

Wildfire: NOOO! IMPOOOSIBLEEEE!

(Then Wildfire explodes.)

Timer: (smirks) Next?

Arachno-Terror: We wouldn't do this… BUT YOU FORCED OUR HAND!

Timer: Powers of Kamen Rider Zi-O Build Armor. COMMENCE!

Wristdriver: Armor Time! Best Match! Build!

Arachno-Terror: YOU WILL NOT WIN!

Wristdriver: Ready, go! Killbus Spider Finish!

Timer: You just bit the decoy, idiot.

Wristdriver: Finish Time! Build! Vortex Time Break!

(Timer destroys Arachno-Terror, and then Skulleton, Slasher, Inferior and Ryugon get angry at him and decide to charge at him, but Vlad decides to take action and kicks Skulleton and Inferior to the wall while Timer whacks Ryugon to the wall, and tailwhips Slasher. Vilgax then decides to backstab them, only for Slasher to cut his head off.)

Slasher: Maybe I made a mistake trusting you.

Skulleton: We will turn Timer into Ohma Timer, whether he likes it or not.

Inferior: All humans will be wiped out.

(Suddenly a C4 bullet blows the kaijus away, and they turn to see the Gotham Knights, Henry Tennyson, and other heroes coming to the rescue. Bat 10 gasps by seeing them.)

Bat 10: (shocked) What?

Wolverine: No way?

Batman (Dick): Another me?

Ladybug: Ryuko?

Riley: Uncle Henry and the Miraculous Warriors?

(Then Henry Tennyson (the alternate Kamen Rider Blade), the Miraculous, the Gotham Knights, the Guardians of the Globe and Rare Rose (Clone of Ruby Rose and Raynare) come in.)

Blade (Henry): Leave my nephew alone!

Red Hood: Or else, we'll make you bleed.

(Then Ladybug sees her teammates.)

Ladybug: I'm glad you came here.

Ryuko: Finally found you.

Queen Bee: Even with your new powers you still need help, huh?

Vesperia: (stern) Chloe!

Queen Bee: I'm just kidding. Right, Mark?

Atom Eve: (glares) You know I'm his girlfriend, right?

(Lucas sees Henry)

Lucas: Never got to see you, uncle Henry. 

Blade (Henry): What can I say?

(Then they turn to the Darkaiju Riders.)

Slasher: (angry) MORE HEROES? HOW MANY OF THEM?

Carapace: We are the Miraculous Knights, from Earth Prime. Ben Tennyson's home planet.

K. Knight: My dad is alive?

Blade (Henry): Indeed. Now let's finish this battle.

Timer: Here we go. Powers of Kamen Rider Zi-O II.

Vlad: Powers of Kamen Rider Kiva Emperor.

Timer/Vlad: COMMENCE!

Wristdriver 1: Rider Time! (Sytheziser tone) Kamen Rider~! (Rider~!) Zi-O! (Zi-O!) Zi-O~! II!

Wristdriver 2: Henshin!

(Then they change to their powerful forms and the heroes charge at the Darkaiju Riders. The Hyperdimension Super Charge Beyond and the Secret Warriors combine their powers and attack Slasher simultaneously, causing him to scream in pain. Kamen Rider Double and their teammates charge at Skulleton and kick him down. Kamen Rider ZO rips off his arms.)

Skulleton: AAAAAAAAAAH!

Sonic: (becomes Super Sonic) Time for the big finish!

(Then Sonic grabs Skulleton and drags him into space where he pulverizes him with his blast. Back to earth, Mega Man.EXE and his team are seen facing Ryugon as Fred burns him.)

Fred: Feel my flames, you vile and kaiju fiend.

(Hiro kicks him to Wasabi, who slashes him, and Gogo Tomago cuts off his tail with her blade discs. Mega Man.EXE blasts him, Gutsman.EXE grabs and slams him and Firestorm uses some nuclear energy.)

Firestorm: Feel true nuclear energy.

(Firestorm blasts Ryugon, and then Blue Beetle and Green Beetle combine their blasts, killing him.)

B. Beetle: Nobody messes with our planet.

G. Beetle: We are the heroes, who protect mankind. 

(The others are seen overwhelming Inferior until Timer and Vlad nod at each other.)

Wristdriver 1: Finish Time! Twice Time Break!

Wristdriver 2: Wake up fever!

Timer/Vlad: RIDER KICK!!

(Then they kick through Inferior and he screams in pain.)

Inferior: (glares at Timer) YOU CAN'T ESCAPE YOUR FATE, TIMER! YOU WILL BECOME OVERLORD OHMA TIMER AND WIPE OUT ALL HUMANS!

(Then Inferior explodes and the hero do their victory pose.)

Vlad: Another victory. 

(Then Timer opens up a portal.)

Timer: We need to reunite with our friends.

Vlad: Right. (to the heroes) So long.

(Then both Timer and Vlad go through the portal. As it closes, the heroes see Slasher getting up, and then the Union Spaceship comes in.)

Ozpin: So they gather all heroes together.

Superman (Kal-El): (glares) Let's make those heroes pay.

(Meanwhile at the portal, Timer has a vision of his other self captured by Wrath.)

Timer: Damn it.

Vlad: What's up.

Timer: I guess there's a counterpart of mine in another Omniverse. And it got captured. 

Vlad: Damn it. We need to save him.

Timer: We will save him later. First we need to reunite with our remaining friends.
