(At Ben's new mansion and headquarters, everyone in the Alien Dino Thunder Megaforce is warned about the situation involving Mazinkaiser, Gundam AGE-FX, Gundam Freedom and other Super Robot Warriors fighting them.)

Ben 10: It looks like we'll have to fight our rivals Mazinkaiser, Gundam Freedom, Devilman, Gridman and all other Super Robot Warriors.

Lucas Wilson: But why? We did nothing wrong?

Slug: He's right, all we did was saving the Union-Verse from its corruption.

Frederick: Well, we weren't in there.

Alexander: Yeah, you did nothing wrong. What did they say?

????: They said we were a threat to them and other people.

(Then Slash, Team Getter Arc and Axel come in.)

Slash: Did we miss the party?

(Then Ryo (A. R.), Powergirl and the others come in. Ben runs up to her and hugs her, and she hugs him as well.)

Ben 10: (worried) Are you alright?

Powergirl: (nods) I'm alright, thanks to Slash, Doctor Strange, Professor Paradox and their new friends.

Ben 10: (confused) New friends?

Noelle: That would be us, Mr. Tennyson.

Uryuu: I am Uryuu Ishida, these are Noelle Silva and Shinobu Kochou.

Shinobu: We are Team Getter Arc.

Axel: And I'm Axel Sentry, the Green Spider. We heard about your problem.

Ben 10: I know, but I have a feeling that Isaac's new fight with me will be more than a rival fight.

Ryo (A.R.): Indeed, Isaac and his team see us as threats.

Auguste: (confused) Why?

Lucas Hart: It's obvious they will come to fight us, what else could happen?

????: TEEEENNYSOOOOON!

(The Alien Dino Thunder Megaforce turns to see Getter Emperor and all of Neo Super Robot Delta Patrol outside their house.)

G. Emperor: (stern) Come out, Alien Dino Thunder Megaforce. Let's see who are thr true defenders.

(Their eyes widen as they see the Neo Super Robot Delta Patrol's members.)

Grimlock: (eyes widen) Okay, we're in big trouble.

Ben 10: Mazinkaiser, Mazin Emperor G, Getter Robo, Grendizer, Venus A, Cyborg 009, Devilman, Gundam Destiny, Gundam Barbatos, Cybuster, Gundam AGE-FX, Gaogaigar, Cutie Honey, Gundam Freedom, Gridman, Weissritter, Gundam Wing, Exbein, Mazinger ZERO and their High Leader: Getter Emperor.

Kevin: We're getting our asses kicked.

Grimlock: Not yet, let's transform.

Auguste: Magna Power!

Ben 10/Lucas Hart: It's hero time!

Luke: It's Morphin Time! Dragonzord!

(Lucas Wilson pulls out his dangerous progrisekey.)

EVERYBODY JUMP!

AUTHORISE!

(A large metallic grasshopper appears behind Lucas.)

PROGRISE!

LET'S RISE! LE-LE-LET'S RISE! (X2)

Lucas Wilson: Henshin!

METALRISE! SECRET MATERIAL HIDEN METAL! METALCLUSTER HOPPER! IT'S HIGH QUALITY!

Santiago: Okay, Fernando... (Fang comes to Santiago) let's do this!

FANG!

JOKER!

Santiago/Fernando: Henshin!

FANG! JOKER!

(Then they transform as well, and then the Neo Super Robot Delta Patrol sees all of the Alien Dino Thunder Megaforce together.)

G. Emperor: I guess there were more than 20 members.

????: Didn't you mean 23?

(Everyone turns to see Rodimus Prime along with his human allies, Gyro Tennyson and Yoko Littner.)

Rodimus: S'up, Oliver. We finally meet again.

G. Arrow: (smiles) Yo, Rodimus. Thanks for being here.

Grimlock: Welcome back, Rodimus Prime.

(Then they shake hands.)

Rodimus: How have you been, Grimlock?

Batgirl: Uh... I hate to interrupt a reunion, but we got a problem.

(Everyone turns to see the Neo Super Robot Delta Patrol.)

Gyro: What the hell, how did they get here?

Yoko: (shocked) I'm shocked as well.

Ben 10: Getter Emperor and his team are here to fight us.

Cutie Honey: (glares at Yoko and Team Getter Arc) You're with them? Traitors!

???? 2: Leave her alone!

(Then everyone turns to see Doctor Strange and Vector Prime.)

G. Emperor: (glares) Doctor...

Dr. Strange: (glares) Getter...

Mazinger ZERO: (glares) Prime...

Vector Prime: (glares) ZERO...

G. Emperor: Your pitful legacy ends here, Alien Dino Thunder Megaforce. From now on, the Neo Super Robot Delta Patrol will be taking over, and you're nothing but lackeys.

Slash: (serious) Did you just call us lackeys? Are you kidding us, you scrap metal!

(The Neo Super Robot Delta Patrol members gasp, and then they glare at Slash.)

James: Is THAT how you thank us for helping YOU? You know what, let's just fight already.

Gwen: (smirks) We didn't even need your help anyway, you bunch of dweebs!

Exbein: (monotone) Said the girl who became a shadow of her own cousin.

Gwen: (cocky) Says the girl who wants to fight boxing even though Kevin could easily knock you out.

Exbein: (angry) WHAT DID YOU SAY ABOUT ME? I'M GONNA KICK YOUR ANIDOTE ASS RIGHT NOW!

Wing: Calm down, we'll fight them soon.

Exbein: (angry) We better.

Sludge: (glares) Better back down, you fallen angel!

G. Emperor: Enough games, Megaforce. 

(Then he teleports everyone to the park as they prepare to fight. The Neo Super Robot Delta Patrol starts slowly charging at the Alien Dino Thunder Megaforce, who then does the same.)

Ultraman: (curious) Ben, they're not stopping.

Ben 10: Neither are we.

(Ben 10 becomes Way Big as the hero teams prepare to fight.)

Vector Prime: Megaforce...

G. Emperor: Delta Patrol...

Vector Prime: CRUMBLE!

G. Emperor: ATTACK!

(Then the fight starts. Vector Prime starts fighting against Mazinger ZERO, Ben 10 (as Way Big) punches Mazinkaiser, Grimlock blasts Getter (Devolution) away, Devilman shoots a beam which blasts Slash away, Gwen Tennyson uses her magic and whips Grendizer.)

(On the north side, Powergirl uses her heat vision on Venus A, who shoots her Koshiryoku Beam. Mazin Emperor G kicks Hellboy to the bench, Green Arrow aims his arrows at Gundam Barbatos.)

Barbatos: Arrows? Against me?

Green Arrow: I had to try.

(Barbatos then punches Green Arrow to the bench.)

Green Arrow: (groans) Man, I missed it bad.

(Superboy shoots his heat vision at Gridman, who shields himself, but Jon flies quickly and sneaks behind him before punching his back. Gridman angrily shoots his Grid Beam, but Superboy dodges.)

Gridman: (stern) Get back here, Superbrat.

(Gridman shoots his Spark Beam at Superboy, who shields himself.)

Superboy: (groans) Not as long as I'm alive, Gridboy!

(In the top of a building, Batgirl is seen fighting Gundam Destiny.)

Batgirl: (glare) You're on, robot Fate wannabe.

Destiny: (glares) You too, Batwoman wannabe.

(They charge at each other for battle.)

(Kim is seen preparing to fight Cutie Honey.)

C. Honey: Come on, Kim. You know you can't beat me!

Kim: (pulls out his Ark Driver) Maybe this can!

ARK DRIVER!

(Cutie Honey's eyes widen as Kim pulls out an Ark progrisekey.)

THOUSAND ARK!

Kim: (angry) Henshin!

SINGURISE! WHEN THE FIVE HORNS CROSS, THE THOUSAND ARK IS BORN! PRESENTED BY ARK.

(Kim becomes Thousand Ark and prepares to fight Cutie Honey.)

JUDGEMENT CONCLUSION

(Red and black energy emanates from Thousand Ark's arm before he extends four spiked metal tendrils toward Cutie Honey, making her scream in pain.)

Thousand Ark: (glares) Your betrayal made me like this, Maki.

(Cut to Magna Defender, he kicks Cyborg 009.)

009: (growls) So you're a Power Ranger, huh?

M. Defender: Indeed, but I also hunt greedy people, abusive people, neglectful people, liars and others. (growls) Now feel my sword.

009: Not until I get to kill you, space bull!

M. Defender: Same as you, cyborg!

(Vector Prime, Spider-Ten (as XLR8), Gyro 23 (as Dinomight) and Rodimus Prime are seen fighting Gundam AGE-FX and Mazinger ZERO. Spider-Ten (as XLR8) grabs AGE-FX's leg with his tail and slams the Gundam.)

Spider-Ten (XRL8): You've got some nerve.

(AGE-FX grabs Spider-Ten and throws him away to crash into the vehicle as the citizens gasp.)

Spider-Ten: (reverts back) I deserved that.

(Rodimus Prime kicks Mazinger ZERO to the side while Gyro 23 and Vector Prime punch him in a combined attack.)

Rodimus: (smirks) What are you gonna do, Iris Lover.

Mazinger ZERO: (glare) You dare compare me to that maverick hunter?

Rodimus: Oh, did we hurt your feelings?

Mazinger ZERO: (glare) I'll show you just how strong the power of Mazin is! IRON CUTTER!

(Mazinger ZERO shoots his Iron Cutter at Rodimus, but Vector Prime shields him, getting stabbed instead, but then Mazinger Zero slams both Vector and Rodimus' heads on each other, knocking them out.)

Mazinger ZERO: No one compares me to that Maverick Hunter!

(Meanwhile, Zero-One and Double prepare to fight Gundam Freedom and Gundam Wing.)

Double: Now, count up your sins!

Zero-One: The ones who can stop you, are us!

Wing: Let's do this!

(Both mechas start shooting until suddenly someone kicks Wing from behind and punches Freedom to a tree.)

Double: Who are you?

Zero-One: And why do you look like Kabuto with some Gatack features?

????: That's because I am both of them combined.

Double: What do you mean?

(Then the figure reveals to be Kamen Rider Kabutack.)

Kabutack: My name is Oscar Anderson, but they call me... KAMEN RIDER... KABUTACK!

Zero-One: And where do you live?

Kabutack: In Beverly Hills.

Double: California, right?

Kabutack: (nods) Yes.

(Then both Gundams get up and glare at Kabutack.)

Wing: Who are you, kid?

Freedom: Another Kamen Rider?

Kabutack: I am Kamen Rider Kabutack.

Freedom: (glares) Never heard of you, but prepare to face us Neo Super Robot Delta Patrol!

Kabutack: (smirks) Shall we, guys?

Double/Zero-One: Yes, let's go!

(Then Wing tries to shoot both Double and Zero-One who prepare to finish the mecha.)

FANG MAXIMUM DRIVE!

METAL RISING IMPACT!

(Both combine their finishers and easily defeat Wing Gundam which explodes, blowing Victor away.)

Double/Zero-One: Hmph, we are the strongest heroes!

(Cut to Kabutack, he prepares to activate his command.)

Kabutack: Double Clock Up!

DOUBLE CLOCK UP!

(Then Kabutack dashes at Freedom hits him nonstop until the gundam gets badly damaged.)

CLOCK OVER!

Kabutack: Rider Kick!

1, 2, 3! RIDER KICK!

(Kabutack jumps up and kicks through Freedom Gundam, destroying it and blowing Shinji back to the park.)

Kabutack: Hey, we should do this again sometimes.

(Both Ultraman and Shovel Knight X are seen fighting Exbein and Weissritter, who hold them down, but Ultraman breaks free, lifts Weissritter up and throws her down before shooting his Spacium Beam at her, destroying the mecha and blowing Hailey away. Shovel Knight X hits Exbein with his shovel, but she grabs it and throws him at Ultraman.)

Exbein: Nobody pisses me off!

(Meanwhile, five miles to Mission City, Doctor Hell and Omni-Man are watching the news about two factions fighting against each other and the former turns to the latter.)

Dr. Hell: Let's start the process.

Omni-Man: (nods) Yes, let's finish our heroic enemies!

(As the screen fades out, Ben 10 (as Way Big) and Mazinkaiser clash their punches.)
