On a clifftop, The Barista and The Scientist carry The Astronaut on their shoulders as they overlook the fight. "With them coming this far from their multiverse, we're closer to home." The Barista said. "I… I have to help them…" The Astronaut said weakly. "Zero, you don't have the strength." The Scientist pleaded. "I'm sorry, but what's left of my energy, I have to help…" The Astronaut spoke before his visor opens, and a beam of light shines, emptying the suit.
"Ben Tennyson… for as long as I can remember, you have been a thorn in my side." Malware spoke. "You have taken a victory from me." Alpha spoke. "You have prevented us from exacting my revenge." Malware spoke. "I was to control the world." Alpha spoke. "Now… you shall perish." Malpha spoke in unison.
Grabbing a nearby facility, Malpha absorbs the building as it turns to dust, growing even bigger as the material adds to his mass until he grows to the size of a building. "How hairy is this?" Jerry asked Finn. "Bear hairy." Finn said before firing at Malpha. With Malpha distracted, Ben runs away and takes shelter in a tunnel. He looks to his Omnitrix, now glowing red.
"Come on… I need another alien!" Ben moaned in frustration. He looks into the tunnel to his right and sees a group of Vulpimancers. "Hi." he said before tapping on the Omnitrix repeatedly. Malpha is now drawn to Finn firing at him, trying to resist every shot at him. "You… you're a very peculiar boy. You're just as annoying as that Ben Tennyson… but different." Malpha spoke.
He raises his fists to slam Finn, Jake, and Jerry, when he is tackled to the side by a giant assailant. He looks up and sees a giant muscular white humanoid with red marking, blades on his forearms, green eyes sticking out of his cheeks, and a massive red head fin. Finn looks up to see the Omnitrix on his chest; this is one of Ben's aliens. "Get away from my new friends!" Ben demanded. "Do you not remember the last time you fought me as Way Big?" Malpha taunted.
"I do, but this time will be different!" Way Big said before plunging a punch downwards. Malpha dissolves into liquid before reforming beside Way Big. He transforms into an alien canine with dark brown fur, sharp teeth, and no eyes that pounces on Way Big. Malpha Wildmutt bites into Way Big, who tries to push him off. Before it could do any more damage, Malpha Wildmutt is pulled off Waybig by something else and thrown aside.
Way Big looks up to see Ursa Kildare: The Voyagers' giant robot motion-piloted by Finn, Jake, and Jerry. "Sorry we're late. I had to call my mom. By the way, meet Ursa Kildare." Finn's voice spoke as Ursa Kildare extends his hand to Way Big. The alien grabs the mech's hand and the two stands side-by-side. "This is Way Big." Way Big introduces himself. They watch as Malpha Wildmutt gets up and faces them
"Remember, he can absorb tech, so keep your distance." Way Big advised. Ursa Kildare nods and deploys shoulder missiles, firing them at Malpha Wildmutt. Malpha Wildmutt leaps and dodges over and around the missiles before one hits him. Emerging from the smoke is Malpha XLR8, zipping by Way Big and Ursa Kildare, slashing them in the abdomen with his claws. "If I was the robot, that would hurt!" Jerry exclaimed.
Simon, Gwen, Kevin and Rook watch the fight atop a facility spacepad. "This is getting bad." Simon said. "Rook, call the Plumbers for backup." Gwen requested. "I did, but it seems they already sent someone." Rook answered. "Who?" Gwen asked.
"Omega." Rook answered as they witness Malpha XLR8 changing into Malware and extending his arms at Ursa Kildare. "Incoming!" Finn exclaimed. Ursa Kildare deploys the Night Blaster and aims it at Alpha when his tentacles wrap around the barrel. "Don't let him touch you!" Way Big exclaimed. The Night Blaster fires an explosive shot, splattering Alpha's arms, reducing them to stubs.
"Aaargh! That weapon… what kind of weapon is it?!" he screamed. "It clearly was a piece of technology, but some force prevented us from assimilating it… what a fascinating world I have been brought into." Alpha spoke. "You okay? Did he touch you?" Way Big asked the team. "We're good." Finn answered when alarms go off. "We're not good!" Jerry screamed.
Their view is rapidly being covered in Mechamorph nanite clusters splattered from the blast before breaking into the cockpit. "We gotta eject!" Jake screamed. "We're going down! Ben, take this!" Finn exclaimed as Ursa Kildare tosses the Night Blaster to Way Big. Jerry transforms his one arm into a blaster to shoot a hole in the glass. Jake grabs them and jumps, stretching into a big parachute as the mech goes down.
Way Big looks down at the shotgun before Malware rushes in and socks him in the face. Way Big is knocked back, but fires back an explosive shot at him. Malware transforms into Malpha Heatblast to throw a fireball in the way, destroying both projectiles before taking flight. He throws more fireballs, which Way Big deflects with the Night Blaster's siding, redirecting them to a valley. He takes aim when Malpha transforms into Malpha Four-Arms and slams his fists down.
At that moment, his top right fist is caught in the blast and blows apart. "My hand!" Malpha Four-Arms screamed. Using this opportunity, Way Big punches him down beside Ursa Kildare. Malpha looks to the mech when Way Big comes after him. He rolls to the side and hugs the mech, absorbing it into himself and sprouting missile racks on his shoulders, firing them into Way Big's face.
Way Big trips over and finds Malpha standing over him. "We were going to annihilate you after we absorb father Azmuth, but we now see you are too dangerous to be left alive." Malpha said before aiming two missile racks in his face. As Way Big stares in fear, a blue laser beam pushes Malpha away. Way Big looks up and stares at his saviour: a To'Kustar with a blue-and-white body, a short head crest, and a blue omega-shaped core on his chest. "Who are you?" Way Big asked him as he is helped up.
"Plumber Officer Omega, at your service." the To'Kustar introduces himself. Joining everyone at the pad, Finn, Jake, and Jerry watch Omega helping up Way Big. Malpha gets up and fires an eye laser, blocked by Omega producing a circular energy shield from his hands. He fires blue energy blades from his head crest, cutting off Malpha's missile racks from his shoulders. "Wow, can I do that?" Way Big wondered.
"Maybe. Some To'Kustars can, some can't." Omega told Way Big. Malpha transforms into Malpha Four-Arms and tears a chunk of earth to throw at them. The two dodge out of the way and cross their arms, firing laser beams at him. Malpha transforms into Malpha Stinkfly to take flight. "Watch this." Omega said as his body is covered in blue cosmic clouds before zipping into the air.
He chases after Malpha Stinkfly in the polluted clouds. "You come to the edge of the galaxy; you deal with the Galaxy Edge Plumbers!" Omega screamed. Malpha Stinkfly fires slime backwards, blinding Omega and forcing him to fall. Believing to be free, Malpha Stinkfly is ambushed by another To'Kustar, one with horns on both sides of his head along with a top crest, blue chest armour, and red stripes along his limbs. "Sergeant Tiger, reporting in!" he exclaimed as he and Malpha Stinkfly crashes down.
"Get it off!" Omega said to Way Big, who burns it off with a cosmic ray. Tiger and Malpha crash down, when Omega stands up and runs to the two. "Who's this?" Way Big asked. "This is Sergeant Tiger, son of Captain Tarrow. He's my superior." Omega answered. Malpha stands up and looks to the three To'Kustars.
"Three To'Kustars. A rare sight indeed." Malpha spoke before transforming into Malpha XLR8 and dashing towards them. Before he could reach them, he is tackled by another muscular To'Kustar with a black-and-red body and a helmet with a blue star and golden spikes on the sides. "Sergeant Titan, reporting in." the To'Kustar spoke, flanked by a slimmer, blue To'Kustar. An entire squad of To'Kustars arrive, encircling Malpha. "So much for an ultra-rare species." Simon commented in awe.
They vary in shape and appearance; one with a blue, trident-shaped crest, one wearing a pirate hat, one wearing headphones, one with a blue ring-shaped core, one with almost sinister triangular eyes, twins of fire and water, and one with two short, curved horns wearing silver upper chest armour and a red-and-blue pattern all over his body. "There's so many…" Way Big said in awe. "We will not allow our plan to end here!" Malpha screamed before deploying weapons all over his body, from missiles to blades to lasers. He fires them all at once, and the squad shields themselves with energy shields. Way Big could stand in awe at the action, giving off a light brighter than Vulpin would ever see in its lifetime.
Tiger picks up the Night Blaster. "What's this?" he asked Way Big. "A gift from a friend." he answered. "I sense dark energy within, but it can be used to serve the light. Just like my Paimogar." Omega spoke as he presented a sword resembling the head of an evil black To'Kustar. "Everyone, channel your energies into this weapon!" Omega commanded.
The To'Kustars line behind Way Big and Omega with their arms crossed and aimed for Malpha. "Now! Unleash your inner justice!" Omega screamed. All the To'Kustars charge up their cosmic rays to channel their energies through one another, firing into the Night Blaster and sending out a rainbow beam into Malpha. "Nooo!" he screamed before being engulfed in light and dissolving into nothing. "We did it… Malpha's gone." Way Big said before reverting to Ben.
"Thanks for the help. He almost wiped the floor with me." Ben thanked Omega as the giant kneels. "Anytime, Tennyson. If you ever return to the edge of the galaxy, you can count on us for help." Omega spoke. As the To'Kustars leave the planet, Omega is stopped by another To'Kustar. "Liu… oh, I thought you were Null." Omega said. "I'm not, but I wanted to let you know that you're gonna be a great apprentice to him." the mystery To'Kustar spoke before flying away.
"I don't need someone to tell me that." Omega said stubbornly. As they leave, Lockdown watches. "Pack it up. We've got enough for the client." he commanded his drones. The rest of the team meets up with Ben on the ground. "That was amazing! That super laser was awesome!" Finn exclaimed.
"We gotta find a way to do that!" Jake suggested. "I think we're done here. It's been great meeting you, Ben 10." Simon said. "I was glad to have you." Ben said. "Can we go home? I need an arm." Jerry said. "Alright, let's go." Finn said before opening a Multiverse Bridge back home and leaving.
"New lifeform identified." the Omnitrix spoke in a computerized voice. "Huh?" Ben said in surprise. "Acquisition failed. Resuming normal functions." the Omnitrix stated. "A new lifeform? Where?" Gwen wondered. In the distance, The Astronaut looks back at Ben's team before leaving this universe with The Barista and The Scientist.
Back in Ooo, the adventurers emerge. "How did I do?" Jerry asked them. "Not bad. You made some bad jests, but you were pretty good overall." Jake said. "About that… when you sat down in the ship, I put flypaper on your seat again." Jerry said. "What?!" Jake said in surprise before looking at his rear, which a sheet of flypaper has indeed been stuck to.
Finn, Simon, and Jerry laugh it off as Jake's face reddens in anger. "Stop laughing and get it off!" he demanded.
THE END
