In the rubble of the garage, Gwen expanded her forcefield and sent the scraps of rubble away from her, Becky, Ally and Emma as Ally groaned and held her arm, a little sore.

"You alright?"

"Yeah, I'm good," Ally said. "You girls?"

"We're fine," Becky said as Emma hugged her sister's best friend.

"Thanks for protecting me, Ally."

"No problem kid," Ally said, hugging her back. "That's what friends do."

"What about the twins and Kevin?" Gwen asked as they heard a stirring and saw Chromastone push the rubble off of him and look at the girls.

"Ben!" she said as she looked to see Rockette push the rubble off of her as well. "And Jen."

Then, she saw Echo Echo suddenly appear along with Discharge.

"And... Ben and Jen?"

That's when the aliens suddenly ran off, a glassy look in their eyes.

"Ben, Jen, come back! All of you!"

"What are you talking about?" Ben asked as Jen levitated the rubble off of them. "We're right here."

That was when the familiar anti-gravity device appeared and levitated up the globs of goo that was Ben's Polymorph form, Goop oozing out of the garage door.

"And over there."

And then, the tiny blue fairy alien flew out of the rubble and flew out of the door as well into the night.

"And there," Jen said, looking at her watch. "What's going on here?"

"That's what I was going to say," Becky said.

It was then that they heard heavy breathing.

"Kevin!" everyone chorused as they all ran over and started pulling the rubble off, including Emma.

"Come on!" Emma said as she put all she had into lifting the rubble off and eventually succeeded, panting heavily after she did so.

"Wow," Jen said, lifting her sister up onto her shoulder. "You've got spunk, sis."

"Thank you."

"You okay in there, Kevin?" Ben asked, pulling the rubble away before gasping at the sight before him.

"What's wrong?" Ally asked before she gasped herself and the other girls did as well.

"What?" Kevin asked. "Half the garage fell on me. Of course I look a little..."

Gwen then pulled out her makeup mirror and showed it to Kevin, who gasped at the sight of his reflection.

He kept his original yet his entire body structure was made out of common elements that he has previously absorbed. The right half of his face, the left half of his chest, the upper right half of his chest, part of his back, and his left arm was made of concrete. The lower right half of his chest, part of his back, his stomach, and his right arm was made of metal. The left half of his face was made of Taydenite, and his legs was made of wood. He only wore a pair of black briefs as clothing.

"...banged up."

"Oh man," Jen said, feeling so guilty.

"No! I'm a monster again!"

"Calm down, Kevin," Gwen said. "Just try to change back to normal."

"Right. Just concentrate."

Kevin closed his eyes and tried to concentrate, but none of his mutations receded.

"It's not working."

"Maybe it's feedback from the watches like the last time he mutated?" Ally suggested.

"But the twins know a lot more about the Omnitrix now. Maybe they can do something?" Becky asked.

"Yeah, right, guys? Guys?" Gwen asked, only to see the twins scrolling through their Omnitrixes.

"Sorry," Jen said as she showed their Omnitrixes. "Look at the Omnitrixes. I'm missing Rockette, Discharge, Frostblight and Stinkbomb."

"And I'm missing Chromastone, Echo Echo, Goop and even Way Big. How did he manage to sneak away?"

"Yeah, that's a good question," Ally wondered.

Suddenly, the Omnitrixes once again, shone out a green and pink light that combined together to show the holographic image of Azmuth, glaring sternly at the twins.

"Ben and Jen Tennyson, I warned you of the consequences of tampering with the Omnitrixes!"

"It wasn't our fault!" Ben said. "The machine just malfunctioned and it was too late!"

"We were just trying-" Jen began.

"To defy my instructions! Well you have succeeded! The escaped Geno Archetypes-"

"What?"

"Your transformations. They will perish if they aren't restored to the Omnimatrixes within 24 hours. And if they do, they will be lost to you two forever."

"How do we get them back?" Jen asked.

"When you are close to them, set the Omnitrixes to Capture Mode. They will do the rest."

"The yellow setting," Gwen told them.

"While I recognize that this incident isn't entirely your fault, I see that you two have gotten overconfident with your abilities," Azmuth explained. "You two have disappointed me greatly, Ben and Jen Tennyson. I shall not help you again."

Ben and Jen then bowed their heads, ashamed as the projection stopped.

"Gwen?" Ben asked. "Can you track our alien forms with their mana?"

Gwen then focused as her eyes glowed pink and then the glow faded.

"No. They're all the same as you two."

"Doesn't matter," Kevin said. "They all have an Omnitrix symbol."

"We can track them with our badges," Becky said.

"I'm coming," Emma said as she stepped up.

"Are you sure you're ready?" Ally asked.

"I think so."

"Okay," Jen said. "You can come with us this time."


Ben, Jen and Kevin drove their cars down the road in a line with Ally driving her bike behind them with their communication settings on as Gwen stood in the front seat of Kevin's car and Becky in the front seat of the DX-Mark 10 and Emma in the backseat of Pink Angel.

Gwen pulled up a hologram of Bellwood as Ben looked at Kevin over the communication setting.

"Hey Kevin? Why don't you change back?" Ben asked.

"Yeah, you've been mutated for like 40 miles now," Jen said.

"I can't."

"Huh?"

"I can't!"

"Guys, weren't you listening back at the garage?" Gwen asked. "He's stuck."

"Sorry," Jen said. "Really. We were kind of focused on our Omnitrixes being on the fritz."

"Let me bring you guys up to speed," Kevin said, eyes on the road. "Thanks to that disaster back at the garage, I can't turn back. I'm a monster."

"We're sorry, Kevin," Ben said. "It was just an accident."

"Yeah," Becky said. "I guess it really isn't anyone's fault. The machine just completely malfunctioned."

"And you are not a monster," Gwen said, placing her hand on Kevin's. "Use your powers. Absorb my skin."

"I'm trying. It doesn't work. I'm trapped like this forever."

"Man," Ally said, bowing her head as all four hubs on the cars suddenly beeped, showing a green and pink symbol.

"We found Chromastone and Frostblight," Ben said.

"Let's go get them," Emma said.


The team looked to see the Pier covered in frost and snow as Chromastone slammed the spinning octopus ride as Frostblight flew by, using her ice breath on everything in sight.

"Not quite the smooth talker they used to be," Ally said.

"Without Ben and Jen's guiding intelligence-" Gwen began.

"Thank you," Ben and Jen said.

"...such as it is, their alien forms are nothing but instinct."

"What do we do?" Becky asked.

"Let's see. Here, Chromastone!" Ben whistled. "Good Chromastone!"

"Oh yeah," Kevin said. "There's your 'guiding intelligence' in action."

"Let's cut the chatter and play," Becky said as the team heroed up and she took out her spear.

Kevin ran in to Chromastone, who blasted him back with ultraviolet rays and into the back.

"Kevin!" Lucky Girl shouted as she avoided a frosty mist that zoomed by her as Kevin stepped up from the destroyed ride, completely unharmed.

"Okay, have it your way. I was looking for a good fight," Kevin said, cracking his knuckles. "And this is all the excuse I-"

It was at this point that his fist suddenly morphed into a metal mace with Taydenite spikes.

"Oh, you are in so much trouble!"

He then used his new mace hand to swat Chromastone, only to get swatted back. Kevin growled as he swatted him back with his mace hand, sending him sliding back on the dock, just as he was tripped up by Huntress' spear as she held it over him.

Chromastone was about to blast Huntress with an ultraviolet ray, only for Lucky Girl to catch this and shield her with a force field that quickly shattered from the powerful blasts.

Huntress and Kevin stood side by side, Huntress docking an arrow into her bow.

"This looks like a job for Humungousaur!" the newly christened Hero Core said as he slammed the core down and transformed into...

"Or Upchuck," the Gourmand sighed. "Upchuck is good."

Upchuck ran at Chromastone and swallowed his ultraviolet blast before he fired it right back at him, causing him to absorb his own blast. This continued in a stalemate for a few minutes as Huntress looked at her arrow and smiled as she switched it for an explosive arrow.

"Maybe I can break the tie," she said as she aimed carefully and fired the arrow at Chromastone, sending him crashing back.

"How did that help?" Upchuck asked as Kevin slammed Chromastone back with a hammer arm and a smirk.

"It put me in a good position to do that. Did that help?"

"Yeah, it does," Upchuck sighed as he set his Omnitrix symbol to Capture Mode and it glowed yellow, absorbing Chromastone back into it.

Elsewhere on the pier, Lucky Girl blasted mana blast after mana blast at Frostblight, who zipped around and froze the floor with a cold blast as Matter Girl slipped into a generator as her hand followed to it before sparking.

"Huh," Matter Girl said as Morph Mistress dodged and hit her Omnitrix, turning into Inferno as she countered the ice blasts with fire blasts and a fiery glare.

"Bring it on, me!" Inferno shouted, blasting forth with a fireball that Frostblight blew through with an icy blast that she flew through with a shout and Matter Girl blasted out with the lightning energy she absorbed that shocked Frostblight, causing her to yelp out in shock as Emma ran up and grabbed the icy fairy alien, squeezing her like a grape in her arms as she struggled to get out as Inferno set her Omnitrix to Capture Mode, catching the Cryosprite inside before she and her brother transformed back, their work at the pier done.

"Okay, two down, six to go," Ben said.


The team drove down the road as Ally yawned on her bike and Emma fell asleep in the backseat.

"We've been at this for hours," Kevin groaned. "We need some rest."

"No time," Ben said, driving down the road. "We need this."

"You're kind of right," Becky said. "You two are going to need your full powers to take on Vilgax."

Gwen adjusted and fixed up her laptop and hooked her badge's USB device up to it.

"What are you doing with that laptop?" Kevin asked.

"I hooked it up to my badge and now I have access to the Extranet. Vilgax has beaten the greatest heroes of ten worlds."

"We're not too worried," Ben said. "We beat him when we were only kids."

"You two should be worried. Those heroes he beat? Now he has all their powers too."

"Not to mention your Omnitrixes are busted," Ally said.

"You broke them!" Jen shouted to Kevin.

"You guys broke them and turned me into this!"

"It was no one's fault!"

Suddenly, they were hit by a massive soundwave that sent them screeching down the road, creating a roadblock as Jen looked on.

"What hit us?"

Everyone was surrounded by Echo Echo clones and looked at each other wearily as Rockette stepped up, holding her guitar with a glare as she sent out a power chord that rocked the cars again as everyone filed out and the Echo Echos fired a wall of sound, combined with Rockette's power chords.

"Echo Echo and Rockette," Jen said as Ally screeched to a stop. "Good combination for us, not to fight against."

"You said it," Ben said as they transformed into...

"Brainstorm!"

"Stinkfly!"

"Ooh, you went Lepidopterran?" Brainstorm asked.

"You should try some more of my aliens on for size," Stinkfly said to her brother before blasting slime out from her eyestalks, blasting the Echo Echoes one by one as the Cerebrocrustacean blasted forth with a blast of lightning to them as well.

"Greetings, my Sonorosian friend, it's time for you to do the right thing."

Echo Echo only blasted Brainstorm with a sound blast as he groaned and Stinkfly flew around the giant fists that were flying at her before she brawled Rockette's guitar with her tail's stinger as her brother looked at the Echo Echos.

"Amusing. Now I must firmly suggest that you stick your posterior back inside my Omnitrix."

Echo Echo only screeched again as Brainstorm glared.

"You realize I am forced to take your inappropriate act of aggression as an act of war, correct?"

Echo Echo only surrounded Brainstorm in clones and blasted him with a Wall of Sound, combined with Rockette's power chords made an absolutely unbearable wall of noise as Emma woke up from her nap inside the car and glared, her fists clenching as she ran outside and tackled Rockette to the ground, surprising her and the guitar fell out of her hands as Stinkfly flew up.

"Sorry I had to do that, sis," Emma said. "I'm only attacking you for your own good."

"Wow," Stinkfly said, flying up and absorbing Rockette and her guitar. "You're brave, little sis."

"Thanks," Emma said, proud.

"I demand that you release me, you inferior twits!"

"I'd do as he says, guys," Becky said, blasting forwards with her arrows, sending the clones flying away.

"They're right next to you, Ben! Just absorb them!" Ally said.

"Oh, right."

Brainstorm then set his Omnitrix to Capture Mode and absorbed the Echo Echoes.

"I mean, really?"

"Sorry. Brain fart," Brainstorm said.


"Are the Omnitrixes working?" Kevin asked as the group drove their vehicles down the city road as the twins briefly turned on their auto-drive setting to check their Omnitrixes.

"Pretty much," Jen said, checking to see she had only Stinkbomb and Discharge missing.

"Once we have all our transformations back, we'll be smooth sailing."

"Aren't you guys forgetting something?" Becky asked her cousin as Emma looked on in the backseat of Pink Angel.

"Uh, no? What else is there?" Jen asked.

"You guys were going to do something in about... five hours from now?" Gwen asked.

"You mean Vilgax?" Ben asked. :We'll fight to the death and beat him like we always do. Nothing more."

"Guys, you've got to get focus."

"We are focused," Jen said. "We have to get our transformations back. We don't stand a chance at beating Vilgax without our full power."

The radars beeped to show two aliens beneath them.

"We've got a read on Goop and Stinkbomb. They're directly below us."

"Did you say, below us?" Jen asked as they all pulled over onto the side of the road and Ally removed her helmet and removed the manhole cover.

"Are you sure Goop and Stinkbomb are down there?" Becky asked as Jen held her sister.

"They have to be," Ben said. "It's a sewer. I researched that Skunkians live off of toxic waste as a food supply. And Goop... well, yeah."

"O.M.G.," Jen said. "The girl in pink going down into the sewer. A match made in heaven!"


Everyone climbed down the ladder into the sewer and Jen and Gwen lit the way with a mana ball in their hands and Ben activated his flashlight setting on his Omnitrix, showing an hourlgass-shaped light.

"Well, look on the bright side," Becky chuckled, looking at the filthy water soaking her shoes. "It isn't as gross as when you two had to fly into Victor Validus' nose."

"True," Jen said as Emma walked beside her, looking up at the mana in her hand.

"Goop and Stinkbomb could be anywhere here," Ben said. "The sewer goes throughout all of Bellwood."

"What else could be here, alligators?" Becky asked, using her spear as a walking stick.

"I heard that people get baby alligators as pets and then flush them down the toilet. They get gigantic in the sewers," Ben said as Emma got a bit scared and Jen glared at their brother.

"Maybe I should go up top and guard the exit," Ally said.

"Aw, big tough Ally is scared of alligators," Jen smirked as Ally chuckled.

"Good one."

"There aren't any alligators in the sewers," Gwen said. "That's just an urban myth."

"Yeah, superheroes are supposed to be an urban myth too," Kevin said.

"Anyway, Jen's scared of spiders."

"There's spiders down here?!" Jen asked, nervous as Gwen pulled at her shirt.

"Hold on," Ben said as he leaned down and saw a familiar circular device in the water. "I found Goop's anti-gravity projector."

"So where's the rest of them?"

That was when the water swirled around Ben and Goop swirled around and wrapped his entire gelatinous body around Ben's body, trapping him.

"Ben!" Jen shouted before she caught a whiff of powerful fumes as she looked to see her skunk alien form over by a sewer pipe, scratching and clawing at the pipes to get at the goodies inside. "Oh no. I am not going to do that."

Gwen and Kevin ran in to help Ben, only to get blasted back by a slime ball each, sending them flying back into the wall before he blasted at the pipes above the area and they came crashing around them.

Becky and Ally ran at Stinkbomb as Becky blasted forth with her arrows, scratching the skunk alien's hide as she hissed at her and Ally gave a powerful roundhouse kick to her.

Stinkbomb glared before she blasted her toxic cloud at her, practically assaulting her lungs as she reached her Omnitrix and transformed into...

"AeroForce!" the Harpian cawed before she ducked her wings into her body and then corkscrewed her way through the cloud, blowing it away as Ally absorbed the metal from the gratae and then morphed her foot into a hammer and performed a powerful roundhouse kick, sending the skunk alien flying back as AeroForce glared and flew in and they scratched and clawed each other with paws and talons.

Ben struggled as Goop was distracted with Kevin and Lucky Girl as he reached for his Omnitrix before he activated it and transformed into...

"Swampfire!"

AeroForce then looked to the transformation Ben made and her feathered eyebrows rose as Goop reformed himself and she ducked and dodged around all of Stinkbomb's gas clouds and blowing them away with her gusts as Goop tackled and ran around Swampfire as they ran down the tunnel.

Goop ran down as Swampfire lit a fireball in his hand with a glare before Lucky Girl gasped in horror.

"Oh no!" Huntress shouted.

"Ben, don't shoot fireballs! This tunnel's full of methane!"

"Full of what?!" AeroForce shouted as Stinkbomb gasped at what she was causing.

Pillars of fire burst forth from the manholes covering the sewers for several miles.

Swampfire simply regenerated himself from the ground and groaned as Lucky Girl levitated the others up and Jen appeared in her Anodite form, holding an unconscious Stinkbomb in her arms bridal style as the skunk alien groaned in slight pain as Jen laid her in her lap and stroked her fur gently.

'There there," Jen literally reassured herself as Stinkbomb smiled at her own touch before adjusting her Omnitrix. "It's time for you to come back home, me."

Stinkbomb only nodded weakly before she was absorbed back into Jen's Omnitrix in a yellow glow.

Emma only groaned as she struggled in the forcefield as Matter Girl held in her arms and stroked her hair.

"You'll be okay," the goth hero said to the five-year old who only nodded.

"Sorry for blowing you guys up," Swampfire said. "I had no idea that would happen."

"It happens when you combine our fire aliens' powers with Stinkbomb's gas clouds," Jen said, crossing her arms as she hovered in the air.

That was when Goop's anti-gravity projector flew in and sliced Swampfire into bits and pieces before he degenerated into solid mush on the ground and his head stuck up from said mush as Goop reformed from the sewers and continued slicing him.

"Hey! Cut that out!"

Suddenly, the anti-gravity device was caught in a pink glow and Goop simply stood in place, barely moving as he struggled against the grip.

"Jen?" Huntress asked as Jen looked shocked.

"I'm not doing this!" she said as Lucky Girl looked and saw the little girl on the ground hold one hand out and looked shocked at her hand as she giggled.

"Huh? Is it working?" Emma asked as she looked at the very tiny pink glow in her hand.

"She's a Spark?" Gwen gasped, shocked.

"OMG," Ally said as Swampfire simply walked over to the paralyzed Goop and absorbed him into the Omnitrix and the glow ceased.

"Unbelievable," Jen said as she powered down and lifted her little sister up.

"I can't believe it either," Emma said. "I just felt like I needed to help you and I just... acted out."

"They're still incredibly weak compared to when we first got our powers," Gwen said. "You're going to need your own training with Grandma Verdona."

"Let's get to the cars," Ben said. "We'll worry about this later."

"Right, big brother," Emma said, hugging her siblings and they hugged her back. "Let's go."


Soon enough, the team was driving along Bellwood in different areas this time, looking at the radars for any sign of Discharge and Way Big with their communicators going.

"It's only an hour away until you guys have to fight Vilgax," Gwen said.

"And all of us are maybe forty miles away from Way Big's location," Kevin said.

"And Discharge is solidified electricity," Becky said. "She could be halfway across California by now."

"We're doomed," Ally sighed before all the team's Plumber's badges rang and they picked it up.

"Yeah, Grandpa?" Jen asked over the conference call.

"It's almost showtime, Ben and Jen," Grandpa Max said as he started to gear up in the Rust Bucket. "And I've been thinking: Vilgax is Plumber's business. As good as you are, you're still just kids. I'll take him on."

"No," Ben said. "This is our fight, Grandpa. Vilgax challenged us. Not you."

"And we're the twins with the Omnitrixes," Jen said.

"At least most of them."

"Are you sure?"

"You made us co-leaders of the Earth Plumber's base," Ben said. "That's the plan."

"You have less than an hour, guys."

"And we're going to win. We've got to go, Grandpa," Jen said, hanging up.

"Jen I might be able to get, but how can you beat Vilgax without Way Big? Aside from Alien X, he's your most powerful transformation."

"That's how you beat him on Xenon, right?"

"And that's how we'll beat him this time too. We'll just stall him," Ben pointed out.

"Until what?"

"We're going to us him as bait for Way Big and Discharge," Jen said. "They love a good fight."


Morning came and the entire Channel 3 New Crew was on the scene at the park that was surrounded by the force field as Psyphon suddenly appeared in a flash and raised his hands to the sky.

"People of Earth, today's challenge is being broadcast simultaneously on all information channels," he announced. "Be forewarned, the Conqueror's Challenge is a courtesy. Vilgax's fleet is currently in orbit around this planet. Should your champions fail to show, Vilgax will declare victory and annihilate the Earth, as is his legal right."

"And if Vilgax chickens out, we win, right?" a voice said and Psyphon looked up to see Ben as Jetray and Jen as Battlefly swoop in through the forcefield and to his feet. "Will you have to work for us then?"

"We kind of hate mowing the lawn at home."

"After the battle, I will personally remove the Omnitrixes from your persons and present it to Vilgax... speaking of whom..."

Psyphon disappeared back into the lead ship and what appeared to be a meteorite came crashing down straight into the area where Jetray and Battlefly were standing sending them skittering back. When the smoke cleared, they looked to see Vilgax appear from the fire, glaring down at his old enemies.

"Ben and Jen 10, I've come to kill you and conquer your world. Is now a bad time?"

"Any time with you is a bad time, Vilgax," Battlefly said as she stood up and hovered above him.

"Are you two ready to die, Ben and Jen?"

"Can we skip with the threats and get to the fighting already? There's a Sumo Slammers marathon at 8 and I forgot to set the DVR," Jetray said.

Vilgax unsheathed his sword and sent up a pillar of fire that blasted the twins, only for them to reappear in a flash of fire in the air.

"That's a yes."

Jetray blasted his neuroshock blasts from his eyes and tail and Battlefly sent a blast of air from her hands that Vilgax immediately blocked with the shield on his left gauntlet.

"Your powers are no match for the Shield of Seagle!"

Vilgax then ran after them as they flew off and leaped in the air and blasted Jetray with the Ruby Ray of Ulo, sendin him crashing down to the ground. He landed and grabbed Jetray's tail and sent him flying into Battlefly, sending both crashing into a nearby fountain in the park, groaning.

He grabbed Battlefly and smashed her into the fountain, leaving a heavy dent in the frame before he moved on to Jetray and continued the process, punching and kicking him before he suddenly transformed and phased through him, freezing him.

"Big Chill!"

Battlefly groaned and touched her Omnitrix symbol and transformed into...

"Grey Matter," she groaned before she leaped out of the dent and ran off and glared hatefully as she pressed it again and turned into...

"Kung Fang!"

Vilgax struggled in his frozen prison as Big Chill spread his wings out.

"Nothing like a refreshing dip on a hot summer day. And Vilgax, you are that dip."

"I will be free!" Vilgax said, blasting his laser vision out and breaking the ice.

"Guess so," Big Chill said, phasing through Vilgax's punch and freezing his hand in the water as Kung Fang flew in and sliced Vilgax with her katanas, shouting out as she did so and flew alongside her brother.

"My hand!"

"You know what they say," Kung Fang smirked. "Cold hands."

Vilgax grunted as he broke his hand from the ice and flew after the dodging twins, blasting his laser vision at Big Chill, who phased through it.

"You've got to let us finish our quips, Vilgax," Big Chill said. "It's sort of a rule."

"Keep joking, children. It'll make my victory all the sweeter."

As he said this, Vilgax adjusted his gauntlet and glowered at Big Chill as he suddenly grasped him, despite the intangibility.

"Hey! You can't touch me while I'm intangible!"

"Oh no?"

Big Chill was then violently shocked from the gauntlet's electricity.

"My mistake," Vilgax smirked as he blasted his laser vision at Kung Fang as she charged at him, sending her crashing down to the ground.

Vilgax then unsheathed his blazing sword and looked towards Big Chill.

"Why don't you pick on somebody your own size? Or better yet..."

Just as Vilgax swung his sword down, Big Chill had already phased through the ground and transformed into...

"Humungousaur!" the 60 ft. Vaxasaurian shouted as he swatted Vilgax away with his tail, before he was blasted with the laser beams as Vilgax hit the ground, sliding backwards.

Kung Fang transformed into Blossom Rose and shouted out as she hit him with her solar beam from the flower bud on her head, sending him back.

"I don't care how many worlds you've conquered," she said. "You're not getting this one!"

She then punched the ground, sending tons of thorned vines swarming around Vilgax and wrapped him up as her brother landed a powerful punch on him.

This sent a powerful shockwave through the area... as Vilgax just broke through the vines and sent the twins crashing into the crater, smashing Humungousaur's face and he grabbed Jen's throat, causing her to reach for it, suffocating her as her green skinned turned an even deeper green.

"Yield now and I promise your demise will be mercifully brief!"

"Don't listen to him, guys!" Lucky Girl's voice shouted and Vilgax looked up to see the others and Emma on Huntress' shoulders hovering on a mana platform.

"Yeah, you guys have beat him before, you can do it again!" Huntress said.

"We've got something bigger than Humungousaur!"

Soon enough, a huge shadow loomed over the entirety of the battlefield and the twins only looked on in shock as Way Big towered over everyone as Vilgax glared outwards.

"Do not interfere with this contest!"

"Who's interfering, squidhead?!" Kevin shouted as Discharge suddenly appeared in a flash of blue lightning and blasted Vilgax back before wrapping herr tail around his arm and yanking him down, cackling like the demon she kind of was before she turned to her host self and smiled, nodding as the twins turned back.

"The twins aren't going to give up so easily, Vilgax!"

"We're just getting started!" Jen said, wrapping her hands in mana as Vilgax leaped back to avoid Way Big stepping on him, landing on his back as Ben reabsorbed Way Big. That was when the human-Anodite hybrid smiled to Discharge and they both high-fived with a smile as Discharge was absorbed back into her Omnitrix.

"Okay, Vilgeek! Let's see how you like a taste of Way Big!" Ben said, slamming down his core and transforming into...

"Chromastone?! Oh, man!"

"Unbelievable," Jen sighed as she shook her head before she opened her eyes, revealing them to be glowing pink as she shouted out as her human form melted away into her Anodite form, shouting out in fury.

Vilgax ran forwards as Jen levitated behind her brother and shouted out as she blasted him with one of her best mana beams, charging him up as he shot forth a super-charged ultraviolet ray, sending Vilgax flying several miles away, crashing straight into the force field and into a ship, utterly destroying it.

"Home run!" Chromastone shouted as he and his sister flew over to Vilgax as he walked out of the wreckage. "What you gonna do now, tough guy?"

"I'm glad you asked," the Chimera Sui Generis said as he encased his sword in crystal and blocked Chromastone's ultraviolet rays and walked forwards, withstanding it as the rest of the Omni-Team walked into the scene (along with Max in his Plumber's Gear) as Jen added her mana blasts to the mix, but Vilgax was just too strong.

"It's over, Omni-Twins!" Vilgax said, decrystallizing his sword and bringing it down on Chromastone, shattering him to pieces before Jen gasped and he plunged his sword straight through her gut, causing her to gasp out in pain.

"I am victorious!"

"NO!" Gwen shouted in horror as she fell into her boyfriend's embrace as Emma gasped out.

"NO! Jen! Ben!"

"I am victorious!" Vilgax said as Psyphon appeared as the Anodite Jen slumped over on the sword, mana tendril hair falling in her face.

"Fetch me my prize," Vilgax said, not noticing as Jen started to heath heavy breaths and her hair started hovering over her.

Psyphon walked over and fetched the Omnitrix symbol from the crystals that used to make up Chromastone and he picked it up.

"Here it is, Master. One of the Omnitrixes. This world now belongs to you now!"

"You're a meanie!" Emma said, running over to Vilgax as Ally gasped and ran over to her.

"What?"

"You heard me! You're a huge meanie!" Emma said. "No one on this planet is going to answer to a bully like you!"

"They won't have a choice," Vilgax told the little girl. "Because you and everyone else on it will be instantly destroyed in a few minutes."

That was when the Omnitrix started glowing green and floated out of Psyphon's hand, the crystals reforming around it as they dispersed to form...

"Diamondhead!"

And at that point, Jen placed her hand on the sword's hilt as Vilgax looked at her in horror, her eyes blazing with fury as her hair burst into flames. She screamed out as she hit Vilgax back with a powerful mana wave as her form transformed (without her in control, btw) into her Master Spark form, phoenix wings flapping as she loomed over him, fists clenching.

"You're in trouble now, Vilgax. We've been doing a lot of practice with our old aliens since we got the Master Control."

"I don't care how many champions you've defeated on how many planets," Jen said, her voice echoing. "You've never fought anything like this."

"Remember Jen, you're extremely limited in how much power your Master Spark form can use."

"I'll keep that in mind, brother."

Vilgax blocked all of Diamondhead's crystals with his Shield of Seagle before he was blown away as Diamondhead leaped over his head and blasted him with several more crystals as Jen flew in and blasted him with a blazing mana ray, sending him crashing into a pillar of crystal formed by Diamondhead as she blocked his ruby ray with a crystal forcefield around herself as she formed four crystals of red, blue, green and yellow around herself before she sent them spinning at Vilgax in an orbit, battering into him and sending him crashing back as she panted, exhausted as Vilgax recovered and slammed Diamondhead through the pillar he formed as Jen raised her hand and formed a massive sword in her hand as her crystals blasted Vilgax with beams of the four elements, sending him panting as Diamondhead went by her and formed three giant crystals over his head and smiled as he looked to his sister.

"Ready, sis?"

"I think so," she said, sweat running down her head and her voice no longer echoing she was clearly exhausted as she held her large sword and her crystals disappeared.

Diamondhead shouted out as he crushed Vilgax with the pillars and Jen shouted out as she brought her sword down, smashing through the crystals and sending forth a massive blast of green and pink. It was at that point that she exhausted her mana powers and she fell to the ground, her Master Spark form fading away into her regular Anodite form and then back to her human form, groaning outwards as Ben transformed back as he helped her up on the massive crystals as they both looked to the battered and bruised Vilgax as he groaned in pain.

"Say the word," Ben said as Jen stood on her own after a few seconds.

"I... give..."

"Yeah, that's right," Jen said. "You do."

"When are you going to learn, Vilgax? You can't beat the Omni-Twins," Ben said. "No matter who else you've beaten, no matter how many powers you have, we'll always have something you don't."

"And what is that?" Vilgax groaned.

"The brother-sister bond we have with each other," Jen said as she and Ben hugged each other. "That's stronger than any power you could ever hope to have."

"She's got that right."

"You did it!" Emma said as she leaped into Jen's arms and they hugged. "You actually beat him!"

"You're right," Ben said. "We did it all by ourselves this time."

"You could've done better if you had our help," Kevin said as Jen smiled and put her hair back over her shoulders.

"Yeah, you're right."


"Vilgax," Max said, walking over as everyone regrouped. "By the rules of the Galactic Code of Conduct as ratified by the Casey-Kelly Accords, you have lost this Conqueror's Challenge. You must leave the planet Earth and never attack it again. Do you acknowledge?"

"I do," Vilgax said reluctantly. "But know this, Ben and Jen Tennyson: I will have my vengeance upon you one day."

"That day ain't coming," Ben said as Jen glared.

"You heard him: get off our planet now or else I'll have Rainbowgon completely annihilate you."

Vilgax and Psyphon teleported away, the entire fleet and the force field disappearing as well from sight.

"Oh man," Ben said.

"What is it?" Gwen asked.

"We were on TV all over the world."

"I guess our secret's out," Jen sighed.

"Well, I used Plumber's Tech to block the transmission about halfway through the battle. Nobody saw Ben and Jen Tennyson. You secret's safe."

"What happened to Chromastone?"

"Who knows?" Ben asked. "His form's not working in this thing anymore."

"Or mine," Jen sighed. "Our Omnitrixes are connected after all."

"But the team's still working, right?" Ben asked as he and his sister put their hands in.

"Right," Gwen and Becky said as they laid their hands in.

"Of course," Ally said, laying her hand on top. "Kevin?"

"I was gonna!" he said, laying his hand on top.

"It's Hero Time," Ben and Jen said in unison.

Emma smiled as Max looked to her.

"So, you have your Grandma's spark too, eh?"

"It's very weak apparently, but yeah."

"She's going to have to give you lessons privately, little one," Max said as Emma sighed.
