In Ben and Jen's house, about a week after the whole grounding thing and their parents finding out their secret, Gwen and Becky were off their subsequent punishment for helping them.
Currently, Gwen was going through Ben's laundry with a disgusted look on her face as her sister and cousins looked on, concerned.
"What's going on, sis?" Becky asked.
"Yeah, tell us about this message already, Gwen," Ben said. "We've got homework."
"Let's just wait for Kevin and Ally. Then we won't have to tell it twice," Gwen said.
"I got that message too," Jen said.
"Then why didn't we?" Ben asked. "Was it an email? Just let us read it."
"It was a telepathic SOS sent straight through our energy fields," Jen said. "Your Anodite gene is still relatively dormant, Ben. You couldn't have gotten it."
"Oh, look, a dollhouse," Gwen said, picking up a Sumo Slammer's arena toy.
"It's not a dollhouse!" Ben said, running over, embarrassed. "It's a Sumo Slammer's Battle Ring!"
"With dolls in it?" Becky asked.
"They're action figures! They're not dolls, they're collectibles."
"They look like dolls to- agh!" Gwen shouted out as she dropped the ring to the ground and Jen shouted out too as she rubbed her head, her eyes glowing pink.
"You girls okay?" Becky asked.
"There's something coming in," Jen said.
A pink holographic message suddenly shot out from Jen's forehead as they all gasped to see the image of a familiar human-Kineceleran hybrid appear in front of them.
"Okay, that's a new one," Gwen said. "Never done that before."
"No way. Helen?" Ben asked.
"Can you hear me, Jen, Gwen?" Helen asked. "Did you find your siblings? We need help in the Null Void!"
The door suddenly opened to reveal the Levins walking in and they gasped at the image in the room.
"Holograms? Seriously?" Kevin asked. "It's never like I come over and you're just playing video games or something."
"I can't hear you," Helen's image said.
"Helen, we're right here!" Ben said.
"It's important. Please help us!"
"It's hard to focus," Jen groaned. "I can't keep the connection."
"It's especially hard with two of us," Gwen said.
"There is terrible danger! We need help desperately! It's a matter of life and death! Please!"
Jen groaned in pain as she fell over, breaking the connection as Ben helped her up and Becky and Kevin helped Gwen.
"You okay, girls?" Kevin asked.
"We're fine," Jen said. "I've just never used telepathy on that scale before."
"We're doing better than those Plumber Kids, though."
"What did they expect going into the Null Void?" Becky asked. "It's not like we didn't warn them."
"We have to go get them out of there," Ally said.
"You're not going in there," Kevin said. "Ask me and Becky. It's-"
"We can handle it!" Gwen said. "We've all done it before."
"No you can't," Ben said as Jen walked up to join him. "There's too much riding on us being here."
"You heard her, they need help!" Ally shouted.
"We know," Jen said. "That's why Ben and I are going alone."
The others all gasped in awe as the twins looked on seriously.
Ben and Jen each had on a green and pink backpack filled with snacks and equipment and a jetpack attachment as they looked to each other and nodded.
"Last time we went to the Null Void, we didn't need all this equipment," Ben said.
"Last time, you had a motor home full of cool state-of-the-art Plumber gear," Kevin said.
"Which you sold to a porcupine con man," Jen said, crossing her arms.
"The point is, it's going to be tricky to get you two out of there," Becky said, holding a harness clip, which she and Gwen attached to the harnesses around the twins waists.
"Even if I'm capable of opening a temporary rift into the Null Void, these cables are the only thing connecting you to-" Gwen began.
"They're not cables," Ally said, shaking her head.
"The Plumber Snake is an unbreakable pandimensional retrieval system worth mucho diniro, which you guys are very lucky I have," Kevin said.
"Aw, you missed us," Ben smiled.
"I've got better ways to spend my time than going to your funeral."
"Us too," Becky said.
Gwen then closed her eyes before she shot her hand forward, eyes glowing pink as a portal swirled open in front of her and she looked to her team.
"I've retraced the energy path from Helen's message. Hopefully, it'll lead you guys to her location but... I don't know how long I can keep this open!"
"Wish us luck!" Jen said as they activated their Omni-Suits and smiled, activating their jet pack functions on their backpacks and flying into the portal, sending the Plumber Snake unraveling behind them.
The twins looked around the area and looked to each other and then pressed a button on their helmets.
"Activating telescope vision," Ben said, adjusting the vision on his helmet's visor and looking through the red void and giant floating islands in the area.
"If this is a pocket dimension, than it must be one big pocket," Jen said.
The twins then looked behind them to see the portal close as Ben sighed.
"There goes our easy way out."
They then heard a massive screaming and saw an green alien getting dragged away by a Null Void Guardian.
"Helpers! Help me! Helpers!"
"We're coming!" Jen shouted as she and Ben flew forwards and then used the cable for the Plumber Snake to wrap around a boulder and then he tossed it towards the Guardian.
The boulder hit the Guardian, who dropped the alien and growled at our heroes as they looked to each other and gasped and ducked, flying away from the creature as it blasted red lasers after them, blasting into the rocks and destroying them.
"This would be so much easier without the leashes!" Ben shouted.
They looked ahead to see a large planet-sized boulder split in two vertically and smiled to each other as Jen looked behind her to the Guardian chasing them.
"Let's see how smart you are!" Jen said as they flew through the planet and came out on the other side before crossing sides.
The Guardian roared as it followed them, only to get tripped up by the cables on the Plumber Snake as the twins fist-bumped.
"That worked," Ben said as they flew down as the Guardian flew away and they met the alien on another rock. "You okay?"
"I knew it! I knew once word of my capture spread, The Wrench would never let me fall into the hands of D'Void! We must flee! He'll be back and not alone!"
"Uh, yeah, okay," Ben said as Jen took the aliens hand and they both flew off.
Later, the twins sat down with the alien with a campfire that they set and they had taken off their helmets, listening to the alien's tale.
"If you two know The Wrench, he must be warned. This entire dimension is becoming destabilized!"
"Slow down, dude," Jen said. "Who is The Wrench anyway? And what are the Helpers?"
"You're not Helpers? But even so, how could you not have heard of The Wrench? He's the only person who dares defy D'Void and his Null Guardians?"
"Back up," Ben said. "We don't understand any of this."
That was when they were suddenly rained upon with a torrent of red lasers as a flock of Null Guardians flew down, roaring towards the twins as they put their helmets back on for protection and they looked on, worried.
"Null Guardians!" the alien shouted.
"Let's do this, bro," Jen said as she and her brother prepared their Omnitrixes.
"Yee-haw!" a loud voice shouted and the twins gasped, looking up to see a flurry of blue lasers raining down on the Guardians.
"Manny?" Ben asked as they saw the human-Tetramand hybrid flying in on a large salamander-like dragon alien. Jen winced as she noticed his lower left hand had been severed and replaced with a robotic claw.
"The Helpers!"
Then, they saw a blue and green blur zooming past, tripping the Guardians up.
"Eat my dust, doggies!"
"Helen!" Jen shouted.
"Come on," Helen said. "We don't have much- Ben?! Jen?!"
"In the flesh," Ben smiled.
"What are you guys doing here?" Manny asked.
"I called them," Helen said. "We need them, Manny."
"Don't worry," Ben said. "We can get you back home. Take our hands. Our friends will pull us-"
"No, Ben," said a familiar voice and they looked to see the Null Guardians being slammed into one another, hard and then Simon leaped in his mech suit towards our heroes. "We're needed here. You don't understand."
They heard the familiar roaring of the Null Void guardians and they looked up.
"It's D'Void."
"The Null King is upon us!" the alien shouted in fear. "All is lost!"
"Not yet, old man," Manny said. He placed the alien on his dragon mount and then slapped its flank, sending it roaring off into the Void.
"Ben, Jen, you guys need to go too," Helen said. "Both of you are far too valuable to fall into D'Void's hands."
"We'll act as decoys and lead him away," Simon said, safe in his mech suit.
"What?" Ben asked. "No way! We're here. We can help you."
"If you knew the two of us at all, you'd know why we can't do that," Jen said. "We're helping you beat this guy, like it or not."
"Nobody can beat D'Void," Manny said. "Find The Wrench. Help him!"
He and Simon both leaped into the air, floating in the void and blasting away at the Null Void Guardians as Helen zoomed off and leaped, bouncing off the floating islands.
"Oh, fine," Ben sighed. "We'll just sit this one out then."
"You're right, Ben," Jen sighed, crossing her arms. "Let's just let our friends do all the fighting and roast marshmallows over the campfire."
The twins then looked at each other and then nodded as they said in unison.
"NOT!"
They both then fired up their jetpacks and flew up to help them, only to find that the cables suddenly shot back, completely straightening and they gasped, almost falling over as they looked back.
"Oh, come on!" Ben said as they both tugged on the cables.
Manny pushed himself off the rocky islands and then blasted away at the Null Guardians floating there as he used his momentum to fly forwards as Simon ran forwards and blasted away with his mech suit, firing a ton of rockets that blasted the Guardians away from him.
Helen zoomed along the rocky islands, avoiding the red laser blasts from the Guardians as they flew towards her.
In one area of the Void, a ton of Guardians flew around in a circle before they parted to reveal a man floating in the void. He had fair skin and white hair with yellow eyes. He had a muscular figure and had a green cape on with black fingerless gloves, black boots and brown pants on and he sneered at the Helpers.
"Who dares defy D'Void?"
Manny blasted away at D'Void, only for the laser blasts to simply bounce off of him.
Ben and Jen looked back from their struggle to see that the man before them had a very familiar face.
"No way," Ben said. "That's not possible."
"It can't be," Jen said, equally jaw-dropped.
"Dr. Animo?!" they both gasped.
A Null Guardian flew behind Manny, sneaking up behind him before swatting him into D'Void's grip.
"What have we here?" D'Void asked as Manny struggled. "One of those annoying little Helpers?"
Helen leaped onto one of the islands before she gasped in horror.
"Manny, no!" she shouted.
"I've got him!" Simon said as he tried to fly forwards, only to be surrounded by a swarm of Null Guardians that flew around him, roaring as he gasped.
Helen zoomed in to help her friend, only to find herself in the grip of the mad scientist as well.
"There's no help for you, Helpers," D'Void said. "And no hope at all."
"No!" Ben and Jen said as they continued to struggle with the cables and then Jen looked at her wrist and looked to her brother as they both nodded before they activated their glowing Omni-Blades.
Back in the Omni-Team's hideout, Ally threw some punches and kicks at the nearby punching bag as she shouted out with each one.
"You're intense today," Becky said.
"I have a right to be. I'm fighting Lynn Loud next week and I need to be in absolute tip-top shape to even stand a chance at beating her," Ally said, panting.
"Makes sense," Gwen said, smiling at her friend's hard work, just as they saw the cables from the Plumber Snake fall to the ground from the portal, slacked. "What happened?"
"I don't know, reel them in!" Kevin said as Becky ran to the controls to the Snake and reeled the cables in, slowly.
"Come on, hurry!" Gwen said.
"This is as fast as it goes!" Ally said.
The cables then fell out of the portal, completely severed from the backpacks and they gasped as Becky felt at the cable and then snatched her hand away.
"Still warm," she said. "They must have cut themselves loose from the cables."
"Why?! It's suicide in there," Gwen said.
"They want to help our friends," Ally sighed. "I would've done the same thing. In fact, I have. And so have you, Gwen."
"They wouldn't do this without good reason," Kevin said. "That wouldn't be the twins I know."
"Now, tell me, Helpers," D'Void said. "Where can I find your leader?"
"It doesn't matter what you do to us, D'Void!" Manny shouted. "We'll never betray The Wrench!"
"Perhaps you will feel differently after my pets are done playing tug-of-war with your friend," D'Void said, smiling to Helen, who gasped in horror.
"No!" Helen shouted as D'Void tossed Manny into the void as the Guardians flew after him, leaving the horrified Simon behind... just before they were completely zapped by electricity, leaving Manny behind.
"Who dares?!"
"That isn't how to tell a joke, miscreant," Brainstrm said as he floated up, holding Manny as Kung Fang swooped up and took her swords out, spinning them in her hands. "First I say 'knock, knock,' and then you say 'Who dares?'"
"You two would mock D'Void?" he asked as Helen struggled in his grasp.
"D'Void?" Kung Fang asked as she helped Simon to an island. "AKA Dr. Animo? Hell, yeah we'd mock you."
"We're doing so now! Albeit, subtly."
The Omni-Twins flew forwards and then shouted out as D'Void grabbed Brainstorm with a smile as Kung Fang stood by, preparing her shuriken.
"You know my name, Helpers? How?"
"Oh come on! Don't you remember us?!"
"Although I'm generally much too modest to boast, on rare occasions... I do come out of my shell," the Cerebrcrustacean said before he blasted Animo with lightning, causing him to shout out and let go of Helen as Kung Fang threw her shuriken forwards that struck D'Void in the chest and she set Helen down. "It is difficult to believe. That electro-encephalitic mind blast should have been more than sufficient to render him insensate."
"No kidding," Kung Fang said. "This guy is much tougher than he was four years ago."
"Believe it, guys. Let's go!" Helen said.
"Right!" the twins both said as they took Manny and Simon and they all flew off into the Void as the Guardians followed them.
"So. The Helpers know my name," D'Void said. "But not for long."
Later on, the team was hiding from D'Void with a father and son who were farming aliens.
One of the Guardians took the crops from the creature before flying away. The second one, however, wrapped its tentacles around the son and then roared as it flew away from the scene, carrying the screaming son alien away with him.
"No!" the father said. "Not my son! I've given you everything you asked for! Don't take my son! PLEASE!"
But it was too late as the Guardian and the alien's son were out of view.
The farmer fell to his knees and then started sobbing hard as Jen bowed her head in sympathy as Ben turned to the Plumbers Helpers. "Come on. We have to help him!"
"No," Manny said, stopping him with his claw hand.
"Manny, what happened to your hand?"
"D'Void is too strong to fight," Simon said. "You don't want to end up like Manny here."
They then went into the house as the farmer went inside and started tending to the fire.
"Thanks for hiding us," Helen said as Jen sat beside him and draped her arm around the farmer's shoulder.
"I'm so sorry about your son."
"D'Void takes everything," the farmer said. "Our only hope is The Wrench. And you Helpers."
"Okay, who's The Wrench?" Ben asked. "Come to think of it, who are you?"
"Yeah, I thought the Null Void was an interdimensional prison," Jen said.
"No, not a prison. A penal colony. Long ago, the Galvan created this pocket dimension so they could banish the criminals from the universe itself. To some, it was a chance to start again. My ancestors have tilled these asteroids since the beginning."
"Overtime, other worlds and even other universes discovered the Null Void and started dumping their criminals here as well," Helen explained. "Some of them aren't even aliens. They're demons. I even encountered a giant fat green demon with black hair in this place who tried to eat me."
"The Galvan had foreseen that problem and so they created the Null Guardians," Manny said.
"It wasn't an easy life, but it was bearable," the farmer said. "Until... he came. D'Void somehow gained control of the Null Guardians. Now, he reigns supreme, conscripting everyone and anyone to dig for cormite in his accursed mines."
"We've tangled with D'Void before," Ben said.
"You have?" Simon asked.
"Yep," Jen said. "In our world, he calls himself Dr. Animo. He has the power to control animals."
"That's how he's controlling the Null Guardians."
"You guys have tangled with D'Void?" Simon asked, confused.
"How did you survive?" Manny asked.
"We didn't just survive. We won," Ben said.
"This invulnerability and the crazy strong thing? That's new," Jen said, rubbing her arm.
"Okay," Manny said. "So you two take us back to Earth, load up on equipment, gather some reinforcements and shut down D'Void once and for all."
"That's not an option, Manny," Ben said. "We cut our tethers."
"There's no way to get our team here to help. We're stuck here just like you."
"Great. Some saviors you brought us, Helen. Can't even save themselves."
Helen rushed over to him and pushed him back.
"Settle down, Manny," Helen said. "They've fought D'Void before. Maybe they can help us."
"Anyway, that's not for us to decide," Simon said.
Later on, the team walked on a rock path as the twins looked on and raised their eyebrows.
"This is where you guys live?" Ben asked.
"This is where he lives. We live wherever," Manny said as Jen smiled.
"This was Becky's camp," she realized. "The Wrench really expanded it."
"Helen," a voice said as they looked up to see Pierce flying in on a jetpack and he crossed his arm. "What have you done? You brought outsiders here? Nobody gets to see The Wrench. Nobody!"
"They're friends, Pierce," Helen explained. "I told you, they're the whole reason we came to find you here"
"Maybe. Or maybe they're just shapeshifters showing you what you want to see?"
"Look," Ben said. "If you want to take us to see your boss, that's fine. If not, we'll find him ourselves."
"There's only one way to get to The Wrench," Pierce said. "Across here and through me."
"Fine by us," Jen said as she smiled to Ben. "He's all yours, bro."
"Good," Ben said as he and Pierce both took off their backpacks. "Some fight. You're a walking pincushion and I'm empty handed."
Pierce smiled and grew a spike from his arm before breaking it off and tossing it to Ben. "Be my guest."
"One spike against 300," Ben said. "You're a real sport, Pierce."
"And you're dead meat, spy!" Pierce said as he ran forwards.
Pierce gave out a few kicks, which Ben dodged with a shout. He then brought his spikes down, which Ben blocked with his with each blow. Pierce got on one hand and kicked down as he shouted out in effort.
"Kick his butt, Ben!" Jen cheered as Helen, Manny and Simon looked at her oddly. "What? He is my brother."
Ben dodged the kick and then used the spike to trip Pierce up, his spikes getting caught in the ground.
Pierce kicked forwards and broke Ben's spike as he propped himself up on his feet as Ben looked at the broken parts of the spike.
"Great."
Pierce ran forwards and Ben tried to parry his blows with the spike halves, but it was no use. Pierce struck Ben's hand with his fist as Ben groaned out, sliding backwards. He looked at his hand as he groaned, seeing spots of red as he started to bleed.
"That was my video game hand!" Ben said, shaking it off.
Ben slid underneath Pierce's legs and tried to attack, only for Pierce to grow spikes from his back and Ben fell off the ledge of the bridge.
The others gasped as Jen ran forwards on mana platforms and scooped Ben up in her arms before she got to the bridge, holding him as she examined his bleeding hand.
"Hang on," she said as she took his hand and wrapped her mana around it, healing the hand in a few seconds before she took a hankie out of her pocket and wiped off the blood with it.
"There's more where that came from, you two," Pierce growled.
"Okay, you win," Ben said.
"You didn't do too bad. At least we know you're human. One of D'Void's spies would've mopped the floor with me in a fair fight."
"Um, actually, I'm only half-human," Jen said, showing off her powers. "That's why I had my brother fight you instead. I knew that if I used my powers against you, you would suspect me of being a spy."
"Yeah, what she said," Ben said.
"But they would't have lasted long after," Manny said, pointing his blaster.
"Come on," Pierce said. "I'll take you guys to The Wrench."
The team then walked into the much larger rocky tent that used to have been owned by Becky for five years before she escaped. It now had a much larger opening and was filled with weapons, computers and a fire pit for cooking.
"I don't need anything he offers you two," Pierce said as he opened the cloth.
The twins winced as they walked up to the cloaked figure sitting by the fire.
"Um, Mr. Wrench," Ben said. "We don't mean to get in the middle of your war, but this whole dimension is destabilizing and-"
"Why don't you tell me about it over a bowl of my famous centipede gumbo?" The Wrench asked, taking off his hood and revealing himself as the twins gasped.
"No way!" Jen cheered as she and Ben immediately hugged their grandfather and laughed along with him. "Grandpa Max!"
"You're alive!" Ben said. "So, are you going to make us ask?"
"Well, when I detonated that Null Void grenade, it didn't blasted to kingdom come. It blasted me here. I meant to come home, but once I saw how badly these people were being oppressed-"
"You took it upon yourself to 86 Dr. Animo's reign once and for all," Jen realized.
"Yeah. Or at least throw a monkey wrench into the machinery."
"Hence: The Wrench," Ben smiled. "And the Helpers: Plumber's Helpers. I just now got that."
"Pierce here helped me round up everyone willing to fight D'Void. But enough about me. What are you two doing here? How did you get here?" Max asked. "And how on Earth did Pierce beat you?"
"I kind of let him win."
"You what?!" Pierce asked, his spikes growing.
"I kind of figured that out on the way," Jen smiled, rubbing at her hair.
"I figured it was the only way you would lead me to The Wrench-I mean Grandpa."
Pierce retracted his spikes and glared at the twins as they smirked.
"What we learned is that the Null Void is actually disintegrating," Jen said.
"Ugh. Then it's happening faster than I thought. Pierce, gather your team," Max ordered.
Ben and Jen stood in front of The Resistance, their helmets under their arms as they looked at Max as he presented a large golden rock to them.
"This is cormite."
"We know that," Manny said, crossing both pairs of arms. "Half the Null Voiders are sweating away in D'Void's mines digging the stuff up."
"Yes. But what you don't know is why."
Max activated a hologram device and activated it, showing his presentation.
"D'Void burns the cormite in this furnace, which feeds his dimensional bore, which is literally ripping a hole in the barrier between the two dimensions," Pierce explained.
"D'Void wants to escape and bring his army of Null Guardians with him to conquer Earth," Helen said.
"Or as Jen and I like to call it, Tuesday," Ben sighed.
"Pretty much," Jen said.
"Guerrilla tactics are no longer an option," Pierce said. "We have to mount an all-out attack on D'Void's citadel."
"Twins, any ideas?" Simon asked to the twins as they smiled to each other with knowing glances.
"Why attack him directly when you can hitch a ride?" Ben asked.
Outside of the farmer's hideout, he loaded up his bagged crops into a large container once again as two Null Guardians wrapped their tentacles around it and then they flew away to D'Void's citadel, not noticing the farmer's sly smirk.
Inside, D'Void's slaves were feeding the mined cormite into the furnace to fuel the bore.
Inside the container with the crops as the Guardian set it down, the other Guardians looked on as a voice suddenly shouted out-
"NOW!"
Max and the Team all ran off, shouting out in fury as they launched their attack on the citadel, running forwards.
The twins both slammed their cores down and transformed into...
"Chromastone!"
"Rockette!"
They both blasted their lasers forwards, blasting into the Guardians that flew towards them as Rockette shouted out and spun her guitar and backflipped over a red laser blast and sliced it down the middle with the bladed edges of her guitar as she smiled.
"Whoa," she said looking at it. "This thing is a real axe. Both figuratively and literally."
Manny jumped forwards and grabbed the tentacles of a Guardian before swinging it around like a mace before tossing it into a ton of other Guardians.
"Let's go!" Helen said, rushing forwards as she sped ahead and then jumped over a laser blast and then kicked into the Null Guardians flying overhead like a pinball.
A Wigsilian Org Beast shouted out and blasted a wave of flames from his maw towards the Null Guardians as the slaves ran in and an Albino Vulpimancer roared outwards and leaped forward, clawing at the Null Guardians that roared forwards and scratched and clawed at it, sending it crashing down.
Simon launched his mech's hand forward and tossed Pierce to a swarm of Null Guardians, prompting him to send all his spikes flying outwards with a cry of effort.
Meanwhile, Max dodged the laser blasts with a shout and then leaped upwards, using his staff to leap onto a Null Guardian and slam it in the head. It then went crashing down to the ground in front of Chromastone as he blasted his ultraviolet lasers outwards as Rockette shouted out and played a power chord outwards, sending a shockwave that blasted into her Null Guardians as she smirked and ran a hand across her mohawk as she looked to Max.
"Is my hair okay, Grandpa?" she asked.
"It looks great, darling," Max said. "You two clear us a path to D'Void. Pierce, you're with me. We're taking that thing out together!"
"Right!" Chromastone said as he blsated a large laser forwards and Rockette shouted out and blasted her power chords out, sending a large pink fist outwards that slammed into the Null Guardians and sending them blasting away.
"Nice work, kiddos," he said.
Suddenly, a familiar shadow loomed over them as they ran forwards to the bore.
"It's not over yet," Rockette muttered as they looked back to see their old enemy walking down the stairs, followed by a huge swarm of Null Guardians as they glared towards him.
Chromastone and Rockette both nodded and fired several ultraviolet lasers and sound fists towards the evil doctor, only for him to block every single shot they threw at him as he glared back down at them and cracked his knuckles. They both timed out and dodged the Null Guardians again.
"Max Tennyson," D'Void smirked. "So you're the mysterious Wrench."
"Guilty as charged."
"And young Ben and Jen. Always a pleasure to try and end your miserable interfering lives."
"Well, Animo," Jen said as she lifted herself and her brother up on a mana platform to their old foe's level. "It's been a long time."
"Too long."
"So are you still a doctor?" Ben asked, preparing his Omnitrix along with Jen.
"What?!"
"Because it hurts when I do this!"
They both slammed the cores down and transformed into...
"Humungousaur!"
"Kung Fang!"
The Chiropterran swooped away as the Vaxasaurian grew to his 60 ft. state and slammed his fist onto Animo, sending him barreling through the destroyed steps onto the ground as they both smirked at their work.
"See?" Kung Fang asked. "We told you it hurts."
"Give me a moment," D'Void said as he pulled himself out of the rubble. "I'll show the pair of you real pain."
"Thanks for the offer, but I think we'll pass," Humungousaur said as he lifted his foot up and stepped on D'Void... only to be thrown off balance as the madman threw him off of him and sent him sprawling away into a wall.
"Ben!" Kung Fang shouted as she flew down and turned into a whirling dervish of sword slices, only for D'Void to block all of them with his wrists as she broke her form and slammed him with a kick to the jaw with a smile.
"It's your lucky day, girly. Too bad it's bad luck!"
He grabbed her wings and then folded them inwards, causing her to scream in pain as he kicked her away into her brother as she sprawled backwards.
"It's a shame to have to end this," D'Void laughed. "But I've almost drilled through the dimensional wall and I have a whole planet to conquer!"
Humungousaur glared as he stood up and slammed his Omnitrix core, transforming into...
"Brainstorm!"
Kung Fang did the same, transforming into...
"Discharge!"
They both displayed their electrical strength as they glared.
"Here's a display of electrocranial power that I know you'll get a charge out of!" the Cerebrocrustacean shouted as he blasted a surge of lightning forward as his sister did the same.
But even with double the power, the lightning did nothing to D'Void as he only laughed and walked forwards, kicking them both away into a wall, sending them sprawling back again as they transformed back to human form, defeated.
"Ben! Jen!" Max said, running up to them as they got back. "Try Swampfire's methane attack."
"It's no use, Grandpa," Ben said. "He's getting stronger."
"And we're getting weaker," Jen added, standing up and groaning.
"When we fought him outside the citadel, Brainstorm scrambled his eggs! But here..."
"Wait a minute," Jen said as she looked to see D'Void absorbing some kind of aura from the citadel. "That's it!"
"Hang tight, Grandpa," Ben said as he and Jen ran off. "We know how to end this!"
"Wait! What are you two doing?"
"Ben and Jen Tennyson fleeing before me," D'Void smiled. "The Wrench at my mercy. And then a world to conquer."
"Sounds like a busy day!" Ben shouted as he and Jen stood at the furnace. "I hope you've had a big breakfast!"
"What?"
"Ben, Jen, get away from there!"
"This furnace," Jen explained. "It doesn't just power the drill, it powers him!"
"That's why he's so much stronger here in his fortress!" Ben said. "And that's why it has to go!"
"Ben! Jen! NO!" Max shouted as they both nodded and let themselves fall off the edge of the furnace.
"Let's end this, bro!"
"Right!"
They both slammed the cores down once again, transforming into...
"Big Chill!" the Necrofriggian shouted.
"AeroForce!" the Harpian shouted as they both circled and blew out a double gust of ice breath and wind blasts.
"Let's see just how cold we can make it."
"Ben, Jen," Max said.
"You'll join them both soon enough," D'Void said.
But just as they were about to fight again, they saw the furnace begin to freeze over and D'Void gasped in horror.
"What?!"
It started to snow down as the rebels and the Guardians stopped fighting as they saw the drill stop going and looked around.
"Impossible!" D'Void shouted as they looked around and saw the citadel start to break down and the Guardians flew away into the distance, all looking on.
"NO! NO!" D'Void shouted in vain as he looked to see Max and ran towards him, only to get punched twice in the face and he fell down, dazed.
"Nice work, guys," a voice said as the rebels looked behind to see Ben and Jen standing on an ice pillar behind them with a smile.
"I did have a big breakfast."
Ben and Jen smiled and slid down the ice pillar to hug their grandfather tightly.
Helen, Manny, Pierce and Simon all cheered in victory as the twins broke the hug.
The Wigsilian War Beast picked up D'Void as Max looked to his second in command.
"Pierce, take care of D'Void. Helen, Manny, Simon, make sure everyone is out of those mines. And keep a look out for any more Guardians. We've still got a lot of work to do."
It was at that point that a magenta portal opened up in the distance and everyone looked to see the rest of the Omni-Team looking on.
"Ben! Jen! Is that you?" Gwen asked.
"Gwen, check out what we found!" Ben said.
"Hi, pumpkin."
"Grandpa!?" Gwen and Becky both asked in joy.
Gwen struggled as she pushed the portal back open.
"I can barely keep this doorway open! You guys have got to hurry!"
"You heard them, Grandpa. Get the Helpers," Jen said. "It's time to go."
"I can't go just yet, guys," Max said. "We have to finish things here. Get those guardians working like they're supposed to. Make sure everything's safe."
"Then we'll stay too," Ben said. "We can help."
"The Earth needs you guys to protect it."
"Then help us," Jen said. "We need you!"
"Not anymore, guys. You two proved that today."
"We can't lose you again," Ben said.
"You never did. We'll find our way back when our work is done here. And besides... I'll always be with you."
Ben and Jen smiled and hugged their grandfather once again as Gwen shouted out.
"Guys! Hurry!" she lifted her hand out as Ben and Jen smiled.
"Oh, and one more thing," Jen said with a smile. "...Grandma says hi."
Max then gained a shocked look on his face as the twins smiled and took Gwen's hand, lifting them into the portal as Ally helped.
"Wait! Verdona's back?!" Max shouted as the portal closed.
"Your grandkids sure have been busy," Helen said with a smile and folded arms.
"Tell me about it," Max said, smiling proudly on.
