Kevin drove his car with Allison driving her bike along the rear as they moved in towards a warehouse before they parked alongside the road and looked forwards as Kevin looked on and folded his arms.

"Are you sure this is the place, Ben?" he asked.

"That's what our tip said," Ben said.

"Yeah, that's what worries me," Kevin said. "You don't get tips. I get tips. You don't have any connections."

"The L-Crew, the Plumbers kids, Scarlett and the Protectors, oh, and now the Miraculous Team," Jen said. "We have plenty of connections, Kevin."

"Oh, and Allison and our cousins."

"It's true. They do know us," Allison smiled as she crossed her arms and moved forwards with Gwen and Becky.

"Real nice support there, Ally," Ben said with a groan.

"We could just go look and see," Gwen suggested.

The twins nodded as Gwen and Jen created mana platforms like a staircase and the team moved upwards to the rooftop before looking through the glass rafter to see the Forever Knights moving a bunch of wooden crates into trucks.

"Forever Knights," Kevin said, absorbing the concrete from the roof.

"Up to no good as usual," Becky said as the team suited up.

"Showtime," Ben said as he and Jen transformed into...

"Chromastone!"

"Discharge!"

Chromastone leaped forward, breaking the glass rafter as Discharge dissolved her entire body into electricity, traveling through the power lines as Kevin, Matter Girl and Huntress leaped downwards, landing beside Chromastone as Discharge appeared and generated electricity from her hands with a glare as Lucky Girl levitated herself downwards and they all took a fighting stance.

"Alright! Nobody moves, nobody gets hurt!" Chromastone shouted.

But, much to their astonishment, they saw the Forever Knights continuing with their business as usual as if the team had never arrived.

"Uh, hello?!" Matter Girl asked.

"Did you hear us?!" Discharge asked.

"I don't think so," Huntress said as she stuck her spear out passed it straight through a Forever Knight, passing through him like thin air.

"Holograms," Lucy Girl realized.

"Good guess," a gruff voice said.

The holograms shimmered sharply before disappearing entirely.

A fish-like alien in a Plumbers suit then pocketed the generator before walking up to our heroes.

"Magister Gilhil of the Plumbers," he introduced. "Magister Prior Gilhil. I'm the commanding officer of this entire quadrant. You're all under arrest for impersonating officers of the law."

He produced his badge and the team all gasped out in shock.

That was when the twins stepped forwards and then transformed back to human form as the others deactivated their suits.

"Under arrest for what?!" Ben asked.

"Impersonating Plumbers. We're the only law enforcement organization recognized by all signatories of the Milky Way Treaty. That makes what you've done an interstellar-class felony."

"Sounds bad," Kevin said as Becky facepalmed.

"If I were you, I'd keep my big mouth in check."

"If I were you, I wouldn't threaten someone who could kick your can halfway up the street and back."

"You feeling froggy, son? Then jump."

Kevin stepped forwards with a glare before Allison laid a hand on his shoulder.

"And if you're feeling smart, don't."

Kevin glanced to Gilhil, who only smirked at him with him returning the favor.

"Ribbit."

He then charged forwards with a punch, only for Gilhil to catch his fist and then moved it downwards, breaking it before he tossed Kevin across the way into a bunch of crates, sending him crashing into the wall.

Gilhil moved forwards and looked plainly.

"Stand down, son."

Kevin growled, pressing his hand against a beam and absorbing the steel from it, giving two strong uppercuts to Gilhil's jaw before he glanced and then looked on.

"As much as I'd love to going a few more rounds with you, I don't have the time."

He stuck a weapon out that shot an orange bola outwards that wrapped around Kevin's entire body and then levitated him in the air.

Ben and Jen went for their Omnitrixes as Gilhil aimed his weapon at them.

"Don't."

"Do," Becky whispered.

Gilhil fired his blaster out as Becky loosed an arrow outwards that broke the bola as the twins slammed the cores down, transforming into...

"Goop!"

"Kung Fang!"

Goop then used his levitation device to move forwards, oozing all around the Magister and knocking his weapon out of his hand as Kung Fang moved forwards and then sliced it to bits with her katanas before sheathing them gracefully as her brother constricted himself around Gilhil, knocking him to the ground before forming his head from the gelatinous mass.

"You wanna talk? Then let's talk."


On the rooftop they were just on, the twins had changed back to normal as Kevin paced around while the others stood patiently in front of Gilhil.

"I don't see why we have to talk to him," Kevin shrugged.

"Because I'm the Plumber officer in charge of this whole section of space."

"Then you would know that we're the good guys," Ben said.

"What I know is that over the last couple of months, I've had several reports of the six of you kids passing yourselves off as Plumbers."

"Our grandfather was a Plumber," Gwen said.

"Max Tennyson. He was a good man. But that doesn't make you Plumbers."

"Um, we're not. We're just superheroes. We're not the only ones on this planet," Jen said.

"And you two," he said to Allison and Kevin. "You don't even have a claim by blood."

"Yes we do," Kevin said. "Our father, our real father was-"

He then turned to Allison, who had her eyes as wide as dinner plates, finally having the truth confirmed for her.

"Kevin? Ally?" Gwen asked.

"Nothing," Kevin shrugged. "Never mind."

"Remember what Xylene said five years ago?" Becky whispered. "Their father was a Plumber."

"The point is," Gilhil continued. "There's a reason we shut down Plumber's operations on Earth five years ago. After Vilgax was destroyed-"

"You mean after we destroyed him," Ben said, folding his arms.

"Credit where credit is due," Gilhil admitted. "But Earth is a backwater Level 2 planet. Without an imminent threat, I can't allow Plumber's resources to be wasted here. I've got over 300 inhabited planets under my watch."

"Look, Magister," Jen said. "Can we call you Magister?"

"The other Plumber we met was named Magister too," Gwen said.

"Magister Labrid, may he rest in peace," Becky said.

"Magister's a rank, not a name," Gilhil explained with a chuckle. "You pretend to be Plumbers, but you know nothing about the job."

"We've never pretended to be anything!" Allison shot.

"Aliens are attacking our planet!" Ben said. "We're just superheroes fighting to keep it safe!"

"We can't just sit here and do nothing. That's not what heroes do," Jen said.

"I've read a number of reports on your activities, Omni-Team. There is no evidence of significant alien activity here."

"We've seen them!" Ben shouted. "We wrecked one of their ships!"

"I've assigned a new Magister to this region. He'll check in on the Earth some time in the next few months. If you have proof, present it to him and let him take care of Plumber business."

"A few months?!" Jen shouted. "But by then, there won't be a world to take care of!"

"I'm inclined to give you kids a break. Ben, Jen, you wear the Omnitrixes so you already have special dispensation. The Galvan have requested that you two not be interfered with in minor matters. And the reports I've read indicate that as you say, you have never impersonated Plumbers. But you, Kevin-"

"Yeah. What?"

"You've got a record. You've done time in the Null Void for a variety of crimes."

"He's changed," Allison insisted.

"He's already done his time," Ben said. "He's been helping us."

"He's been impersonating a Plumber. Give me the badge you stole," he ordered as Becky sighed, reached into her pocket and produced the badge she took from Mike and placed it in his hand.

"Don't take my badge, man. Please."

"Now. Or you're going back to the Null Void."

"Just do it," Allison sighed, bowing her head.

Kevin reached into his pocket, produced his Plumber's badge and then dropped it into Gilhil's hand.

"Thank you."

Gilhil then pressed a button on the badge, shutting it down.

"You're free to go. But if you ever get involved in Plumber business again, I don't care what Azmuth says, you're all going to the Null Void. Even you, Ben and Jen."

The team then bowed their heads as Gilhil pressed a button on his suit and teleported away in a flash of blue light.

"Is this really it?" Ben asked.

"Is this the end of the Omni-Team?"


The next morning at Mr. Smoothie's, Ben and Jen got the collection of smoothies as Kevin sighed on his car with Gwen and Allison comforting him as Becky leaned against the car, sighing.

"Cheer up, guys," Ben said. "Mr. Smoothie makes everything better."

Kevin took a smoothie and then immediately spat it out in disgust. "How does turnip and wheatgrass sludge make anything better?"

"Well, I like it," Ben said as the others immediately took a step back from him. "Besides, it's also got ginger in it."

"Oh, ginger. That solves all our problems," Becky said, rolling her eyes.

"Seriously, Ben," Gwen said. "Magister Gilhil pretty much just put the Omni-Team out of business."

"What are we gonna do now?" Allison asked.

"We're gonna keep doing what we've been doing," Jen said. "Find the Plumber's kids, fight the bad guys."

"He said he'd put us in the Null Void," Becky said. "I am not going back there unless I absolutely have to."

"He also said Plumbers never come around here anymore," Ben reminded. "We'll worry about when, or should I say if he ever shows up again."

"He took our badges," Kevin groaned.

"Badges? We don't need no stinking badges," Ben said.

"You think this is a joke, Tennyson?!" Kevin shouted, taking Ben by the jacket in anger.

"Kevin, let him go!"

Kevin then shouted out and tossed him onto his car, spilling the smoothies everywhere.

"Dude!" Jen said.

"I wanna be a Plumber, okay?!"

"So do I," Allison said as she looked to him. "When we were little, our mom would tell us stories about our dad. How he was a Plumber and how he did all this cool stuff. I thought she was fibbing back then, but now I know it's real."

"We never met your Dad," Gwen said.

"Me either," Kevin said.

"You did. You were just an infant then," Allison said. "You wouldn't remember. I was about four years old when he died."

"I still want to be like him," Kevin said. "Make him proud."

"That's why you know so much about the Plumbers and alien technology and everything," Becky realized.

"It's why I agreed to help you guys in the first place... mostly."

Kevin opened the car door and sighed.

"I need my badge back. It's the only thing that matters."

"I'm going with you," Allison said, getting on her bike. "For Dad."

"For Dad."

The two then drove out of the parking lot, leaving the Tennysons shocked at what had just happened.


Meanwhile, at a Highbreed base of operations, a group of DNAliens walked along the space, setting up some devices before looking up to hear some footsteps slowly approaching towards them.

The figure stepped out of the shadows to reveal himself as wearing a grey and black suit with silver gauntlets and a silvery mask on his face that concealed everything.

The leader of the DNAliens signaled his comrades to blast their slime balls at him, only for him to counter them with dark energy blasts before sending a dark energy beam forwards, knocking the DNAliens down.

He walked forwards towards the door to the base before ripping it from its hinges. The DNAliens wielded their laser lances forwards which blasted into the figure, but doing little damage. He glared and blasted an energy beam forwards that knocked them down before approaching forward.

A section of the ceiling opened over him and a DNAlien dropped down on him, only for him to grab his neck and then he threw him towards the wall, knocking him out.

Two more DNAliens walked forwards with laser lances and then the figure blasted forwards with his energy blasts, knocking them out just like the others before he broke the door off of its hinges and crumpled it up like a piece of paper and tossed it at the figure before him, sitting on his throne.

The figure turned himself around to reveal a Highbreed commander.

"Who are you?! What insignificant alien speck dares to enter the command center of a Highbreed lord?"

The figure said nothing as he approached the Highbreed with a glare.

"It doesn't matter. Dead men don't need names."

He simply swatted the figure towards the wall, creating a crater and kicking up a cloud of dust as some debris fell on him. But he simply lifted the debris off like it was nothing and tossed it aside.

"Nice shot," the figure finally spoke. "You're just as strong as I've heard."

The Highbreed hissed before unfurling his wings from his form as the figure tossed a piece of debris towards him and walked forward as the Highbreed recovered and growled angrily.

"That's it. Show me all your power."

The figure let loose a beam of energy that enveloped the Highbreed in a black and white aura, draining him of his energy.

"Give me your strength."

Once all his energy was gone, the Highbreed groaned out in pain on the ground as the figure kicked him over.

"What... do you want from me?"

"I want to make a deal."


At the Omni-Team's headquarters, Kevin was tuning up his car in the garage on the underseat as he saw two feet step in front of his car before he pushed his bench out to sneak a peek.

"Who's out there?"

"Us," Gwen said with Becky by her side, holding a cup. "I brought you something to cheer you up."

"Yeah, thanks anyway-"

"It's not a smoothie," she said, shaking the ice-filled cup before taking a sip. "See, regular soda."

"Yeah, okay," Allison said as she cracked a soda from the seat by her as Kevin took a sip.

"We were in the neighborhood and came by to see how you were doing."

"Fine, you know," Kevin said. "Listen, the two of us don't want to talk about our dad."

"It never crossed our minds to be honest," Gwen said. "I brought you a present."

She then took out a small bag and tossed a ball to Kevin, and he looked at the strange ball.

"What are these?"

"A wooden ball. Absorb it."

Kevin then absorbed the material from the ball, coating his hand.

"How about this one?" Gwen asked, tossing a metal ball to him, which he absorbed.

"Ball bearings made out of... ball bearing stuff," Becky explained.

"Stainless steel."

"We brought you a whole bag of them, all made of different materials," Gwen said. "That way, when we're on a mission, you and your sister can absorb anything you want."

"Thanks, but it doesn't really work that way unless you're really experienced," Allison said. "He need a lot of whatever we're absorbing to coat ourselves entirely until he gets more practice."

"Oh."

"And what makes you think that I'm still helping you guys anyway?"

"Because you changed," Becky said.

"Maybe, but I'm still on parole. That Magister can put me back in the Null Void any time he wants."

The four then sighed before they heard a crash and a rumble, looking to see the Highbreed lord form a hole in the wall with a glance towards them.

"Human scum!" he shouted. "I will cleanse the world of your filth!"

"Looks like I gave up the wrong day to give up fighting monsters," Kevin said, absorbing the material from his car.

"You think?" Allison asked as the team all transformed into their hero suits and glared at the Highbreed.

"It's a Highbreed," Gwen examined. "The twins said that they're too strong for us to fight."

"Well the twins ain't here!" Kevin said as he ran forwards, absorbing the concrete from the ground and ran to the Highbreed, punching him in the face and gut, but he stood solid before grabbing his face and tossed him into his car.

"Kevin!" Matter Girl shouted as she ran forwards, absorbing the stainless steel from the ball bearing and kicked him, punching backwards, morphing her hands into steel maces and punched him in the gut and head with a shout of anger as Huntress ran forwards and kicked him before whacking him with her spear with a shout as he grabbed her spear and tossed her into Matter Girl, sending them both back as Lucky Girl looked up with a gasp.

She then sent her glowing hands forwards, wrapping the Highbreed up in her mana grip before he used his strength to burst out of her grip, sending her to the floor alongside her sister and Matter Girl.

"Sis!" Huntress said as she shook Lucky Girl away and they looked to see the alien lord looming over them as Lucky Girl created a force shield around them that the Highbreed pounded down on, cracking it severely.

"That won't save you, human!"

He finally punched a final blow to the shield, causing it to shatter like glass before punching forwards as the girls all shouted out in fear... only for the sure-to-be-fatal blow never to come.

They looked up to see Kevin block the blow from them, causing the concrete armor to crack and fall off him before he fell into Lucky Girl's arms, unconscious.

"No!" she said. "How could you?"

"Like this!"

He reeled his arm back to attack, only for it to get grabbed by Ben as Humungousaur, who glared hatefully at him.

"Hey, ugly! Why don't you pick on somebody your own size!?"

He spun and tossed the Highbreed upwards through the roof of the headquarters and into the air as Firefox came rushing in and fired a flame blast from the roof onto him, which sent him crashing to the ground, forming a crater.

"I wouldn't if I were you, mate," she said as she saw him getting back up.

The Highbreed cursed in her won language as a beam of blue light came down and Magister Gilhil was standing there with a glare towards the Omni-Team.

"Didn't take you kids long to get yourselves into trouble again, did it?"

"US?!" Humungousaur asked. "We were just-"

"Attacking me for no reason!" the Highbreed shouted.

"You're the one who attacked us for no reason!" Huntress shouted.

"He's one of the aliens we told you about, mate," Firefox said. "They're attacking the Earth!"

"Sure, they are, kids. I want some proof."

"They attacked me for no reason. They said they were Plumbers."

"I've heard enough. You six are under arrest. And you, I don't know what's going on here, but I'm gonna find out. You're coming with me for questioning."

"I beg to differ," a voice said.

All eyes turned to see the figure that the Highbreed had met back in his lair.

"Nobody's going anywhere. Not until I make your power my own."

He enveloped his hands in his black aura and blasted forwards, sending everyone back as Lucky Girl shielded herself and Huntress as the figure blasted at the Highbreed, who was convulsing on the ground.

"Why?" he asked. "You promised that if I helped you- argh!"

"I can't be trusted."

The Highbreed, Humungousaur, Firefox, Matter Girl and Kevin all groaned out as they felt their energies being drained out. Humungousaur growled as he activated his growing powers, towering over everyone as he grew to sixty feet and his stegosaurus features grew more pronounced.

"I've almost forgotten how strong you and your sister are... Ben."

He then doubled the dosage of his power onto the twins they each groaned outwards in pain before they were forced out of their transformations and sent sprawling to the ground with a thud.

"Who are you?" Ben asked. "And how did you know who..."

Jen gasped in realization before turning to Lucky Girl and Huntress.

"Gwen! Run!" she shouted.

"What?"

"You've got to get out of here! You're our only hope!" Ben shouted. "Run!"

They then both groaned outwards, falling unconscious as Lucky Girl deactivated the forcefield and sent a mana wave forwards to counter his blast before running for the dirt as Huntress ran beside her.

Lucky Girl then created a forcefield around them as they both hopped over the wall.

"You can't run forever, lovely Gwen. Or you, Becky. I'll have my revenge on you, too. But first thing's first."

He turned to the six unconscious figures before him and stepped forwards.


They met back at a familiar hideout by the river as they were all stuck in some sort of energy tube, wrapped in chains and hanging in suspended animation.

"I don't understand what's going on," Gilhil said. "That's the guy who tipped me off that the six of you were impersonating Plumbers."

"Yeah, and he scammed big ugly too," Kevin said, causing the Highbreed to growl at him.

"He's got a point, dude," Allison said. "He did. Don't snarl at us."

"We know who he is, Magister," Jen said.

"Do you really?" the figure asked as he looked at them from the ground.

"Of course we do," Ben said. "You'd have to be somebody who knows all about the Plumbers and the Highbreed to pull this off. But most importantly, you'd have to be someone with a grudge against us."

"Yeah," Jen said, glaring hatefully. "Why don't you take off that stupid mask... Michael?!"

"Wait," Kevin said. "That's Michael Morningstar?!"

"The creep who stole all his powers from us and those girls at his prep school?" Allison asked.

"When you ruined my plans, you nearly destroyed me. But over the weeks, my powers returned, stronger than ever. But so did my hunger. My old method of feeding is no longer sufficient."

"Oh, so the high school girls are too tough for you, huh?" Ben asked.

"On the contrary. I needed more power than they could supply. Michael Morningstar no longer exists."

He then reached for his helmet, pulling it off and fully revealing himself to the team, who recoiled in disgust at his ugly zombie-like appearance.

"Now, I am Darkstar. You did this to me and now, you will feed my hunger."

He then blasted his black energy beams forward, beginning to drain his prisoners dry of their energy as they groaned in pain.

"I will take your strength and make it my own until you have no more to give!"

"Can you reach your Omnitrixes?" Kevin asked with a groan. "Maybe Alien X?"

"No!" Ben shouted.

"If he absorbs all of that power, nothing will be able to stop him!" Jen groaned.

"Eventally, I'll have it all anyway," Darkstar said.

"Mike!" Gwen shouted.

He turned to see the two sisters glaring as Huntress cracked her knuckles.

"Ew," Becky said at his appearance. "I swear that you were better looking when you and my sister went out."

"Hey, I was there too, you know!" Jen shouted weakly.

"Laugh while you can. I have all the power of your teammates, plus the Highbreed and Plumber combined. How can you two possibly hope to defeat me alone?"

"Who said we were alone?" Gwen asked with a smirk.

The windows suddenly burst open and tons of DNAliens came through the windows and doors to surround Darkstar.

"They're pretty mad about you kidnapping their boss."

They charged forwards and Darkstar hurriedly drained the energy from them one by one, leaving them as empty husks as he tossed them aside, only for him to more to charge as he drained their energy as well as they swarmed him hard.

Gwen snuck by the distracted Darkstar as she blasted forwards to the field generator, dissipating the shield as Kevin and Allison absorbed the metal from the chains before breaking them and doing the same to their teammates and Gilhil.

"Thanks, kid," the latter said to Kevin.

"What about me?" the Highbreed asked, still chained.

"Hang in there. We'll get you later," Ben said as the team ran forwards to Darkstar, who was up to his eyeballs in DNAliens.

"There's too many to absorb!"

"And the bad news keeps on coming," Gwen said as she blasted forwards to Darkstar, who flew back as Allison ran forwards and slammed him with her spear as the twins transformed into...

"Echo Echo!"

"Firefox!"

Echo Echo let out a sonic scream combined with a fireball from Firefox, as Darkstar fell into them and Gilhil blasted them before they quick-changed into Spidermonkey and Kung Fang with a swift double-kick and he fell into a hammer arm from the Levins as they transformed into Jetray and Discharge as they let loose a blast of electricity and neuroshocks to him, sending him sprawling downwards towards the hole as he groaned in pain as he saw a flash of green.

"Nighty night," Humungousaur said as he dropped on him, creating a powerful crater and sending debris flying as Gwen protected the others with a shield.

Becky and Allison looked around to see nothing else.

"The Highbreed is gone," Becky said.

"The DNAliens must have sprung him while we were fighting," Kevin surmised.

Darkstar groaned in pain as the twins transformed back and panted in exhaustion from the amount of energy they exuded.

"You okay, guys?" Allison asked the twins.

"Tired," Jen said.

"Sit down and catch your breath," Gwen said.

"Good idea," Ben said as they sat down and started breathing.

"Is everything okay?" Gilhil asked.

"Everything's spinning," Ben said. "Going dim. Need... smoothie..."

"They're fine," Becky smiled as the twins fell asleep.


After the twins woke up, the team faced Gilhil, who had Darkstar in energy cuffs and inside an energy tube to keep him prisoner, smiling on proudly at them.

"You sure that rig will hold him?" Kevin asked.

"It's Level-6 technology, son. He isn't going anywhere but the Null Void."

"What about us?" Jen asked, folding her arms.

"I've been giving that some thought. You guys made a difference today."

"And?" Ben asked.

"Maybe I don't need to send good men to this quadrant. Maybe they're already here."

"What's that mean?" Kevin asked.

"You six have been drafted. Here's your badges back," Gilhil said, handing the badges back to Kevin and Becky, who smiled gratefully. "And some for you four as well. As of now, you are the only law enforcement in this quadrant. Do a good job."

He then pressed a button on his suit, teleporting away with Darkstar in tow as the Omni-Team examined their new badges.

"Alright!" Becky said, rolling her fist as Allison examined her badge with a smile.

"We're Plumbers," she said. "Officially."

Kevin smiled as he walked off.

"Hey, where are you going?" Jen asked as she pocketed her new badge.

"I've got to tell my Mom."

"Wait," Allison asked. "Mom's here? In Bellwood."

"Sure. I told her where we were and she packed her bags and got an apartment here. Wanted to be closer to her kids."

"I'm going too! I haven't seen her in forever!" Allison said as she ran up and they ran alongside each other, leaving behind four smiling Tennysons.


Next time on Ben and Jen 10:

Alone Together
