(The Avengers (MHA-Verse) are seen taking the citizens to Times Square to make sure they won't disobey Superior Iron Man's orders, but suddenly they see a beaming light as Mazinkaiser, Getter-1, Great Mazinger, Grendizer, Devilman and Venus A come in.)

Mazinkaiser: (glares) Your reign of terror ends here.

Getter-1: You're crazy. No, BATSHIT INSANE!

G. Mazinger: Yeah, stop overpowering your show.

Grendizer: It's not too late.

Devilman: Let us help you.

Venus A: We can work together to face Superior Iron Man.

Iron Man (MHA): (glares) Never!

Black Widow (MHA): Prepare to die!

(Suddenly Captain America kicks Iron Man in the gut and jumps to the Neo Super Robot Warriors' side.)

C. America (MHA): (to Mazinkaiser) Time to get back to my old ways: Fight for Freedom!

Mazinkaiser: There's the Captain America I know!

(Ant-Man, War Machine and Ronin join the Neo Super Robot Warriors too.)

Ant-Man (MCU): Let's call it a truce.

Ronin (MHA): Yeah, just like in the Civil War.

War Machine (MHA): Sorry Tony, but this time, I'm on Steve's side!

Iron Man (MHA): Okay, have it your way... traitors! 

(Iron Man then calls the newly rebuilt Ultron.)

Ultron (MHA): Prepare to die, Captain!

(The heroes get in their fighting stances.)

Mazinkaiser: Let's do it!

Captain America (MHA): Heroes Assemble!

Devilman: (smirks) Oooh, it will be FUN!

(They start fighting as Steve fights Tony, and both Mazinkaiser and Venus A fight both Carol and Thor.)

C. Marvel: (glares) You will die and be wiped out.

Mazinkaiser: Fat chance! ROCKET PUNCH!

(Mazinkaiser blows her away with his rocket punch while Thor strikes Venus A with his Thunder Bolts, but she avoids and prepares to shoot.)

Venus A: PHOTON BEAM!

(Venus A blasts Thor into several buildings, and then the God of Thunder gets unconscious as he's reduced to dust.)

Venus A: Don't mess with the best!

(Mazinkaiser blocks Black Widow's attacks and grabs her.)

Mazinkaiser: You don't have to do this!

B. Widow (MHA): I don't care. 

Mazinkaiser: So be it! (throws Natasha) PHOTON BEAM!

(Mazinkaiser shoots a beam from his eyes, and burns Natasha to dust.)

Mazinkaiser: Sorry, you forced me to do this...

(Devilman is seen evading Rocket Raccoon's bullets.)

Devilman: Yo, Rocket. You don't have to do this. There's still...

Rocket (MHA): No, I lost my friends, and my hope got buried with them!

(Devilman then tackles Rocket Raccoon and knocks him out with a punch.)

Devilman: Bad end for you. HA!

(Great Mazinger is fighting Hulk as they clash their punches.)

Hulk (MHA): HULK SMASH GIANT ROBOT!

(Great Mazinger punches Hulk away from him, and then he grabs and throws Nebula into a wall. Suddenly a portal comes out and sucks Nebula.)

G. Mazinger: Huh? Where did she go?

(Meanwhile at Showa Megaforce-Verse, Reality Earth, a portal opened up as Nebula crashed into the ground, then two remaining dust turned into Thor & Captain Marvel back in MHA-Verse forms. As they got back up, suddenly a golden dust sprinkled on them as their memories were erased as they confused.)

Nebula (MHA): (confused) Where are we?

C. Marvel (MHA): (confused) I don't know, all I remember are weird dreams...

Thor (MHA): I guess we're in the real world. No Midgard... no Asgard...

(Then they hear stomps as they see a giant fighting a mechanical kaiju.)

(It's Ultraman Geed fighting Mecha Gomora. Their eyes widen, but then they see some Class 1-A students fighting kaijins.)

Izuku: Bring it on!

Bakugo: I'm not done with you yet, extras!

Shoto: We'll stick together.

(The three MHA Marvel Heroes decide to help them while Geed fights Mecha Gomora.)

(Back to Heisei Megaforce-Verse, Earth Prime. Great Mazinger sees Hulk charging at him, but then Ant-Man (MHA) stomps him.)

Ant-Man (MHA): Giant Man smash Hulk!

(Meanwhile Captain America and Iron Man are still fighting each other, but Ronin notices something behind Steve and someone behind Iron Man.)

Ronin (MHA): LOOK OUT!

(Steve suddenly gets stabbed by Neo Granzon while Tony is punched through the chest by Evol.)

Ozpin/Evol: So many Iron Men... I better take this one's armor off and set to help those other Megaforce Heroes from the other Iron Men... (sighs) That goddamn Ironwood...

(Ozpin/Evol then disappears without a trace as Kaiser Dormammu shows up.)

N. Granzon: Thanks for bringing me back, Lord Dormammu.

K. Dormammu: No need to. Soon no one will stop us Kaotic Villains from conquering the Omniverse.

(The Neo Super Robot Warriors decide to follow Ozpin/Evol as the Kaotic Avengers Army comes out to flank Dormammu.)

K. Dormammu: (smirks deviously) Now let the Omni-War begin.

(As the screen fades out, Kaiser Dormammu and Chronoa glare at each other for war.)
