(In the Solar Dimension, Zero is currently laughing)
Zero: Yes, it's about time Monster Kid faces off against me.
(A giant rock creature appears next to Zero)
Zero: It's time to cause some destruction on Earth.
(Back in San Fransokyo, It was a normal day as people were doing their usual business when a portal opens as Zero walks out from the Solar Dimension and arrives on Earth with some Terradrons)
(Zero roars as everyone was screaming in terror)
Zero: That's right humans, runs for your miserable lives!
(Meanwhile at the Stewart Mansion, Max, Dennis, Megan and Daisy are watching a NASCAR race until a news report)
Max and Dennis: Aww.
Bluff: We interrupted your regular schedule program for this importing news.
Dennis: What could be more imported than race cars.
(The screen switches to Zero standing on top of Sycorax)
Bluff: These are live footage of where the alien monster known as Zero is currently on his way to Sycorax with several one-eyed creatures.
(The Stewart siblings are shocked)
Dennis: Oh no.
Max: Zero's here?
(Meanwhile, Zero and the Terradrons are marching their way to Sycorax, only to be blocked to the Blight Force)
Queen Blight: Not so fast Zero.
Zero: (glares at the Blight Force) The Blight.
Princess Blight: Mom, he's glaring at us.
Zero: So, I get to destroy three members of the same beings who help defeated me on Earth all those years ago.
(The Blight Force get ready is fighting stances)
Queen Blight: Our kind may have defeated you in the past, but we'll stop you.
Zero: How? You could've prevented King Ghidorah from destroying your homeworld, what makes you think you're going to stop me from conquering this planet?
King Blight: Let's show you.
(The Blight Force charge energy auras in their hands)
Zero: I've been waiting millions of years to get revenge of the Blight.
(The Blight Force charge at Zero, the latter eyes glow red as one of the Terradrons appeared from behind them)
King Blight: What?
Zero: A surprise attack, destroy them.
(The Terradron was prepared to generate a eye beam at the Blight Force, only to be destroyed by an energy beam)
Zero: What?
(Zero saw Salavak dives towards the ground)
Zero: Finally.
(Salavak lands on the ground and morphs back into Max)
Max: Hello Zero.
Zero: So, surprise to see me Monster Kid?
Max: A little, I didn't expected to see you in person in person Zero. Why are you here?
Zero: Why to kill you of course and to retrieve Garnos.
(Max morphs his hands into pincers)
Max: That's not gonna happen.
Zero: You're really going to fight me? How amusing.
Max: I can't believe I'm gonna fight him.
Zero: Terradrons, attack the Blight Force and Big Hero 6!
(The Terradrons did what their master commands them and went to attack Big Hero 6 and the Blight Force)
Baymax: Oh no.
King Blight: Alright
(Max shoots energy beams from his pincer claws at Zero, the latter leaps into the air and slams his hooks into the ground, creating a shockwave which blows Max away)
Max: (gets back up) That blows.
(Zero flies straight towards Max and projects laser eye beams at him)
Max: Oh no!
(Max dodges the beams, develops wings and flies in the air)
Max: I bet you can't fly.
(Zero flies into the air as well)
Max: Okay, nevermind.
(Max morphs his hands into hooks as he and Zero clash with each other)
(Meanwhile, Fred is burning the legs of a Terradron as it falls to the ground)
Fred: Another win for Fredzilla!
(One Terradron is chasing Go Go, trying to shoot laser beams at her)
Go Go: Uh hello, alien monster trying to kill me!
(Baymax flies Hiro and Honey Lemon to the Terradron)
Honey Lemon: Don't worry Go Go, we're here...
(Princess Blight gives the Terradron a powerful kick, sending it to the ground)
Hiro: That a good kick.
(Princess Blight lands near Go Go)
Go Go: I can see why Max likes you.
Wasabi: Uh, guys.
(The rest of the Terradrons were ganging up on Big Hero 6 and the Blight Force)
Hiro: We're in trouble.
(The Terradrons emit soundwaves which causes Big Hero 6 and the Blight Force to collapse as they are all pinned to the ground)
Hiro: Hey, what's going on?
Baymax: It appears we are forced to submission.
Fred: Guys, I starting to think we are paralyzed!
Go Go: I can't move!
Honey Lemon: Me neither!
Princess Blight: We're trapped!
(Max saw what's happening to his allies)
Max: Guys?
(Zero emits sonic soundwaves from his mouth at Max, sending him straight across the ocean)
Princess Blight: (straining) No!
(Big Hero 6 and the Blight Force struggle to free themselves, but no avail)
Wasabi: (straining) It's no use guys, this stasis field is too strong.
Zero: (lands near the captive heroes) That's right human, the Terradrons are useful for many reasons, creating stasis fields to trap my enemies.
Fred: I don't suppose you gonna let us go free and leave.
Zero: No, I'm gonna destroy all 9 of you at once.
(Zero's eyes glow)
King Blight: No!
Zero: Time for you all to...
(Suddenly, Zero gets kicked in the face by Max, sending the interdimensional being to the ground, leaving a rut)
(Zero gets back up, shocked to see Max)
Zero: What? You're still alive? I thought I send you into the ocean.
Max: Yeah, well it turns out...
(Max suddenly disappears in a flash)
Zero: Where did he...
(Max appears behind Zero)
Max: I can teleport!
(As Zero turns around, Max punches him in the face with his fist and strikes his archenemy with a series of jabs and kicks while teleporting)
(The Stewart family arrives as they walk out of the car)
Harold: It's Max!
Mary: Oh no!
Jade: He's fighting Zero.
Megan: This is bad.
Dennis: Come on Max, kick his butt!
(Max stops and saw his family)
Max: Dennis?
(Zero notices Max's family and laughs)
Zero: So, your family is here.
(Zero flies into the air and teleports above the Stewart family)
Max: Zero, don't!
(Daisy hugs Dennis tightly)
Daisy: I'm scared Dennis.
Zero: Maybe I should destroy Monster Kid's family just to see him cry.
(Zero flies down towards the Stewart as Mary, Jade, Megan and Daisy scream)
Max: NO!
(Max teleports in front of his family, develops wings and launches himself into the air towards Zero)
Zero: What is he doing?
(Max starts glowing)
Zero: What?
Max: Nobody threatens my family!
(Max screams as he launches towards Zero and manage to strike a direct hit on the interdimensional creature's chest, causing him to shriek in pain)
(Everyone looks shocked)
(With Zero weakened, Max uses his superhuman strength to elbow strikes him on the back, sending him pummeling to the ground, leaving an impact)
(Zero groans in pain as the Terradron went to their master's aide, releasing Big Hero 6 and the Blight Force in the process)
(The Terradrons carry Zero as he opens up a portal and he glares at Max, the latter lands his feet onto the ground)
Zero: You may have won the battle, but the war still continues! I'll be back Monster Kid!
(Zero laughs as the Terradrons carry him into the portal as it closes)
Max: I'll be waiting for you Zero.
Mary: (offscreen) Max!
Max: Mom.
(Mary charges at Max and hugs him along with the rest of his family)
Mary: Max, are you okay? Did that monster hurt you?
Max: Don't worry Mom, I'm fine.
Harold: We're glad you're okay.
Daisy: I was worried about you.
Dennis: We were all worried when you went to fight Zero.
Max: I know, I actually won a fight against my own archenemy.
(Big Hero 6 and the Blight Force)
Fred: That was epic!
Hiro: Totally amazing.
Go Go: Nice job.
King Blight: I don't believe it, you actually beat Zero in a battle.
Queen Blight: Indeed, you was able to stand your grounds against him.
Princess Blight: You saved us from being obliterated by Zero's eye beams. Thank you.
Max: You're welcome.
Megan: How did you teleported?
Max: Well it's starting wh..
(Max spits out a black egg which hatches into a round-shaped one-eyed creature floating in mid-air, leaving everyone shocked)
Go Go: Wow.
Wasabi: That's unexpected.
Daisy: (claps) Yeah!
