Gwen 10: The Celestial Twins

Chapter 1: And Then, There Were 20

Act I

It all began in outer space as a sinister ship attacks the other ship, somewhere out near Jupiter.

"Hull damage: 20 percent, weapons system's still operational.", the drone lieutenant reported.

"I have come too far to be denied. The Omnitrixes shall be mine, and there is not a being in the galaxy that dares stand in my way.", the villain named Vilgax growled.

Meanwhile, on Earth, Gwen was picked up by Max Tennyson in the van.

"Now, before we go to our vacation, I'm picking up Ben and Jen from school.", Max spoke.

"That sounds great, Grandpa. At least when it comes to Jen.", Gwen responded.

Speaking of, Ben and Jen Tennyson, both of which had white shirts with black stripes were sitting in school as the former crafted a paper air-plane, proceeding to throw it at the back of his teacher's head, making him gasp before looking back at Ben, who was poorly pretending to read his book, smooshing his face in between the pages as Jen gave a glaring sigh.

Act II

The clock was ticking as Ben is waiting for the bell to ring.

"Come on... Come on...", Ben spoke, looking at the clock as Jen was paying attention to the teacher.

"And I just want to remind you all that I will be teaching summer school this year, and it's not too late to sign up!", the teacher reminded.

"Yeah, right.", Ben retorted.

"Will you keep it down?", Jen whispered.

Then, the bell rang.

"Yes! Outta here!", Ben shouted excitedly.

"Everyone, have a good vacation, and I hope to see you all again in the fall.", the teacher spoke as the students ran out with Ben walking toward the classroom door.

"Benjamin, could I have a word with you before you go?", the teacher asked as he held up Ben's paper air-plane before Ben huffed and walked over to the teacher's desk.

Later, outside. Cash Murray and J.T. backed a boy named Jamie to a tree.

"Normally, we'd take your money and beat you up. But since it's the last day of school, we're going to give you a break. Now fork over the cash, so we can get out of here.", Cash demanded before Ben stepped forward first.

"Leave him alone!", Ben urged before Cash and J.T. turned to notice Ben.

"Get lost, shrimp.", J.T. only responded.

"I said, back off!", Ben only reiterated.

"Oh, looks like we got us a hero. Suppose we don't wanna back off?", Cash smirked.

"What are ya gonna do about it, Tennyson?", J.T. added before the three stared intently.

But before anyone could do anything, Jen appeared.

"Didn't you hear him? He said 'Back off!'", Jen urged.

"Oh, boy.", J.T. spoke in slight worry.

"Ah, forget it. We'll take care of that later when school starts after summer vacation.", Cash responded before they walked away.

"Are you okay, Jamie?", Jen asked.

"Yeah. You're a hero.", Jamie grinned.

"Really? Well, I wouldn't go that far.", Jen responded just as Max pulled up in the Rust Bucket.

Come on, you two, let's go! We're burning daylight. I wanna to make it to the campsite by nightfall.", Max requested.

"Coming!", Ben and Jen shouted at the same time.

Then, Ben and Jen got in the Rust Bucket.

"I have so been looking forward to this!", Ben grinned referring to the camping trip.

"The only person left is...", Jen began before she noticed Gwen sitting down at the table.

"Gwen!", Jen grinned.

Ben, however, wasn't very happy.

"What are you doing here? What is she doing here?", Ben asked.

"Take it easy, dweeb. This wasn't my idea. Somebody convinced my mom that 'going camping for the summer would be a good experience for me'.", Gwen responded.

"Grandpa, please. Tell me you didn't?", Ben asked nervously.

"I thought it would be fun if your cousin came along with us this summer. Is... that a problem?", Max asked.

Ben and Gwen didn't say anything, but their glares say otherwise.

"Well, at least I get to hang out with you, Gwen.", Jen grinned.

Then, the Rust Bucket pulled away from its stop, revealing the license plate just before Ben and Gwen started bickering at each other.

"Aw, I can't believe it. I wait all school year to go on this trip, and now the queen of cooties is along for the ride.", Ben bickered with Gwen.

"Hey! I had my own vacation already all planned out too, you know? Each activity is color-coded, so I never do the same thing two days in a row.", Gwen argued as she pulled out her schedule before Ben raised his eyebrows.

"Now, I'm stuck with my geekazoid cousin going camping for three months.", Gwen added.

"Geek.", Ben spoke to Gwen.

"Jerk.", Gwen retorted.

"It's gonna be a long summer.", Jen sighed as the Rust Bucket drove out of Bellwood onto Route 66.

Later at night, the group of Tennysons gathered in the woods around a table-bench.

"Chow time!", Max spoke, bringing out a bowl of food to the kids before plopping down a bowl of still-wriggling worms, much to Ben, Gwen, and Jen's disgust.

"Okay, I give up. What- is that?", Ben asked, pointing to the worms.

"Marinated meal worms. Hard to find them fresh in the states. You know, they're considered a delicacy in some countries?", Max asked.

"...And totally gross in others?", Gwen complained as one of the worms fell out the bowl and crawled on the table.

"If these don't sound good, I've got some smoked sheep's tongue in the fridge?", Max suggested.

"Ugh. Couldn't we just have a burger or something?", Ben asked as he, Gwen, and Jen smiled at Max.

"Nonsense. This summer's gonna be an adventure for your taste buds. I'll grab the tongue.", Max spoke before walking away to get said tongue.

"Okay, I got a half-eaten bag of corn chips and a candy bar in my backpack. What do you got?", Ben asked to Gwen.

"Some rice cakes and hard candy.", Gwen responded.

"Think we can make them last the whole summer?", Ben asked before the two sulked together .

"Well, I brought enough fruits and veggies to last us the whole summer.", Jen responded.

"I guess anything's better than those worms at this point.", Ben responded.

Meanwhile, Vilgax's ship continued attacking the other, blasting lasers into the hull of it.

"Their propulsion systems have been destroyed.", the drone lieutenant reported.

"Prepare to board! I want the Omnitrix, now!", Vilgax ordered.

However, the ship getting chased primed a laser blast and fired, directly hitting Vilgax's control room, blasting him across. But immediately after, the warship retaliated, blasting the ship to pieces. Out of those pieces, a small pod shot down into Earth's atmosphere, but not before releasing its circular cargo.

Back on Earth, Ben and Gwen were sitting, playing with their electronics while Jen was holding graham crackers and chocolate bars.

"Who wants to roast marshmallows?", Max asked.

"I'm even making them.", Jen added.

However, Ben and Gwen continued playing with their electronics.

"Okay, um… How 'bout we tell scary stories?", Max suggested.

"Scarier than having to spend a summer with your freak of a cousin?", Ben retorted before laughing to himself as Jen only growled with a glare.

"I'd like to, Grandpa, but I'm busy doing a web search on cures for extreme 'doofus-ness'. Nothing yet, Ben, but let's not give up hope.", Gwen refused with an added joke for Ben.

"Aww, come on, you two. We're all in this together.", Jen responded.

"Jen's right. You can mope around like this all summer, or we can have some fun. Now whadd'ya say?", Max agreed.

"I vote for moping.", Gwen responded.

"Geez. It's all you've been doing ever since Renee disappeared.", Ben responded before gasping upon realizing what he just said.

Then, Gwen gasped after hearing how Ben would be so inconsiderate as to bring up something personal to her before giving a glare with a humph.

"I-I'm sorry. I didn't mean to go that far.", Ben apologized.

"On second thought, I'll take a hundred mile-long walk just to get away from him.", Gwen responded angrily as she closed her laptop and stormed off in a huff.

"Gwen, wait!", Jen shouted before turning with an unforgiving glare toward Ben.

"You are in so much trouble when I get back with Gwen!", Jen growled before she ran, catching up to Gwen while Max shook his head to Ben in disappointment.

"Okay. That was too far. Even for me.", Ben admitted.

Gwen was walking on her own through the forest.

"I can't believe this. Being stuck with a doofus is one thing, but Ben mentioning my lost sister? This is gonna be the worst vacation ever.", Gwen groaned just before Jen caught up.

"Gwen, wait up!", Jen shouted before catching up.

"What are you doing here?", Gwen asked.

"I know you want some space from my brother, but you can't just go by yourself. Besides, I just want you and Ben to get along for once in your lives.", Jen responded.

"After what he said? Never!", Gwen responded.

"He didn't mean it. Even he could tell he went too far.", Jen responded.

"Then, maybe he shouldn't have said it at all!", Gwen retorted angrily.

Just then, a meteor shot across the sky, with Gwen and Jen looking up at it.

"Whoa! Is that a shooting star?", Gwen asked.

"No. I think it's more like a meteor.", Jen replied.

Soon enough, the meteor instantly changed course, aiming straight for Gwen and Jen, making the former gasp.

"I was right! Totally a meteor!", Jen shouted before the meteor crashed right behind her and Gwen as they ran, causing smoke and debris in the air.

As soon as the smoke cleared, Jen and Ben looked on at it, getting to their feet for a closer look.

"Okay. I stand corrected.", Jen spoke.

"Yeah, but if it's any consolation, it's no shooting star, either. Looks more like a satellite or something...", Gwen responded before the ground beneath the two and the crater crumbled, causing them to give a slight scream as they fell in.

As they get to their feet again, they looked at the pod, with it opening to reveal two ominously glowing Omnitrix.

"Watches? What are they doing in outer space?", Gwen puzzled.

"I'm not sure. But we'd better be careful just in case.", Jen suggested.

Then, Gwen nodded before stepping closer to the pod, cautiously outstretching their arms to pick up the watches. But as they do, the two Omnitrixes suddenly leapt from the pod and onto their wrists, latching themselves to Gwen and Jen with the former's changing to a color scheme of blue and pink contrary to gray and green, taking Jen half as aback as Gwen, although Jen was still surprised.

"Ahh! Get off me! Get off, get off!", Gwen shouted as she struggled with the watch on her arm.

"Dang it! It's stuck on me, too!", Jen grunted before both fell over, and climbed out of the crater, screaming as they ran.

"Grandpa!", Jen and Gwen shouted as they ran.

Back at the campsite, Max was a bit worried.

"Hm. They've been gone a while.", Max spoke.

Normally, Ben would enjoy some time off from Gwen, but after what he inadvertently blabbed, he's not so sure.

"Ugh! I had to go and open my big, dumb mouth about Renee.", Ben groaned.

"There are some things we can't change, Ben. Our mistakes is one of them. But I'll tell you what. After we eat some s'mores, then we'll go look for them.", Max assured.

Meanwhile, Gwen and Jen were trying to pry the watches off with sticks before they broke, leaving them hopeless at getting them off.

"Well, that didn't work.", Jen spoke.

"Well, it's official. We can't get them off. I wonder how this thing works.", Gwen puzzled before she pressed a button below the dial on her Omnitrix.

"What the...?", Gwen puzzled before glancing around and looked back to her Omnitrix with the lines intersecting each other with a silhouette appearing.

"Well, this is weird.", Gwen commented.

"Yeah. I've never seen a watch do this before.", Jen responded.

"So, do you want to press it?", Gwen asked as she turned the dial, showing more silhouettes.

"I mean, what if it's dangerous?", Jen asked as she did the same thing.

"Well, only one way to find out I guess.", Gwen responded before she and Jen looked down at their watches and put their fingers on top of each dial before their eyebrows raised and they pressed the dials down before then being surrounded in a pink light (green for Jen), which dimmed down to show hot rocks forming on Gwen's arm before stretching across her body, turning into some sort of alien made of rocks and fire with Jen then growing pale green scales while her fingers and feet become webby. Then, afterwards, she grows an anglerfish-like antennae in her forehead before she grows gills and then her skin turns the same color as her scales before her teeth grew too big for her mouth before they became exposed as sharp teeth before opening her eyes with Jen and Gwen shouting.

"Aah!", the transformed Gwen and Jen shouted in panic.

Act III

Both Jen and Gwen were screaming in the forest.

"Aaah! I'm on fire! I'm on fire!", Gwen shouted.

"Aaah! Get that shark away from me!", Jen shouted before both then started to calm down.

"Hey...I'm on fire...but I don't feel like it.", Gwen realized.

"Yeah. And I think I'm the shark.", Jen realized herself.

Then, Gwen walked out to a hill and aimed for a spot where she can practice her new abilities before letting loose a blast of fire, writing her name into the sky.

"Now, that's what I'm talking about. I think this alien could use a name. How about, 'Pyroflash'?", Pyroflash grinned.

"Wow. That is a cool name. I wonder if there's a lake somewhere for whatever Alien I am.", Jen pondered.

"Wanna find out?", Gwen asked as she turned around toward Jen, inadvertently stepping on a dry leaf with Jen noticing it.

"Gwen, no! It was a dry leaf you stepped on!", Jen shouted, pointing to where Gwen stepped before she saw the spreading wildfire created.

"Uh oh. Oh man, I am so going to get busted for this.", Gwen groaned.

Meanwhile, Max was sitting by a campfire outside the Rust Bucket as Ben walked out, seeing the smoke from Gwen and Jen's escapades in the distance.

"What's that?", Ben asked.

"Looks like the start of a forest fire. We better let the Rangers' Station know. Probably some darn fool camper out there, messing around with something he shouldn't.", Max guessed as he got up before pausing as he and Ben come to a realization.

"Gwen!", Max shouted.

"Jen!", Ben shouted at the same time Max shouted before he quickly opened a camping-kit and grabbed two fire-extinguishers, passing one to Ben.

"Better take this!", Max suggested.

Then, the two ran into the Forest toward the smoke overhead.

Meanwhile, Gwen and Jen were concerned about how to put out the fire.

"This would be so cool, if it weren't so...not cool!", Gwen spoke in worry.

"Oh, I wish I can put out this fire somehow.", Jen groaned before suddenly releasing a water blast at part of the forest fire, putting it out.

"Oh. I guess my wish is granted.", Jen grinned.

Meanwhile, Ben was putting out fires by spraying the extinguisher up until he shot it at Pyroflash's back, causing her and Jen to turn around to notice him before Ben screamed.

"Look... I know we look weird, but there's no reason to be scared...", Jen began before Ben quickly clobbered her round the head with the extinguisher, knocking her down.

When she tried to get to her feet, Ben then sprayed Pyroflash's head, knocking out the flames around her rock-y body for an instant.

"Hey!", Pyroflash exclaimed while coughing before her flames returned just as quickly.

"I don't know what you two are, but you'll stay down there if you know what's good for you!", Ben warned before Pyroflash, staying down, gestured to Ben's shoe, setting a small flame on it with a chuckle.

"Ow!", Ben exclaimed as he hopped on one foot until he put the small flame out.

"Was that really necessary?", Jen asked.

"I warned you!", Ben exclaimed, raising the tool above his head to hit her.

"Don't even think about it, jerk!", Pyroflash retorted before Ben quickly realized who they were.

"Dweeb? Jen? What happened to you guys?", Ben asked.

"Well, when we were walking, this meteor fell from the sky and almost munched us, except that it wasn't a meteor, or a satellite for that matter. It was more like a pod for the watches Jen and I found that jumped up onto our wrists, and when we tried to get it off, I was suddenly on fire only it didn't hurt and she practically became a shark before I accidentally started a forest fire.", Pyroflash explained just as Max caught up.

"Ben, are you alri...", Max began before he was abruptly cut off as he saw Pyroflash and Jen as a sort of inverted mermaid.

"What in blazes?", Max asked.

"Hey, Grandpa, guess who?", Ben asked.

"It's us, Grandpa.", Jen waved.

"Gwen? Jen? What happened to you two?", Max asked.

"Look. We don't have time to explain right now.", Jen responded.

"No kidding. Major forest fire burning out of control, remember?", Ben agreed.

"So, what do we do?", Pyroflash asked before Max thought of an idea.

"Backfire. Start a new fire and let it burn into the old fire. They'll snuff each other out. Think you can do it, Gwen?", Max asked.

"Shooting flames? Seriously? It's all I can definitely do at this point.", Pyroflash responded.

"Great idea. And I can put out the fire with this alien's powers. Don't ask how yet.", Jen responded before Pyroflash ran a distance and shot flames into the fire.

"Looks like I'm up.", Jen guessed before then spraying at the fires, putting them out with naught but smoke escaping.

"Hey. Not bad. I should call this alien Flash Flood.", Flash Flood grinned.

Later, a Yosemite Park Ranger came across the burnt out forest, puzzled to find it out out as quickly as it started.

Meanwhile, Vilgax's ship was being repaired by drones while recuperating from the other ship's blast.

"What do you mean it's not there? This battle nearly cost me my life, and you say the Omnitrix is no longer aboard the transport?!", Vilgax asked.

"Sensors indicate a probe was jettisoned from the ship, just before boarding. It landed on the planet below.", the drone lieutenant reported.

"Go. Bring it to me.", Vilgax urged you a nearby drone beside his rejuvenation tank.

Back on earth, Pyroflash and Flash Flood explained their situation to Max as they were eating marshmallows by the fire.

"And you say that these watches just jumped up and clamped onto your wrists?", Max asked before Ben tossed a marshmallow to Gwen.

"Yeah. That's pretty much it.", Pyroflash responded.

"Think they're gonna stay monsters forever?", Ben asked.

"They're not monsters. They're aliens.", Max corrected before Ben, Pyroflash, and Flash Flood stared at him inquisitively.

"I-I mean… look at them, what else could they be?

"I don't wanna be 'fire girl' forever. How am I suppose to wedge this into my schedule?", Pyroflash asked.

"Yeah, I'm not sure I want to be stuck like this either. Right now, fire and water don't mix.", Flash Flood agreed.

"Don't worry, you two. We'll figure this thing out.", Max assured before both Omnitrixes beeped and flashed red lights before they over took the duo and reverted Gwen and Jen back to human form.

"Hey! We're us again!", Gwen spoke excitedly.

"Finally. I thought I was gonna freak out.", Jen sighed in relief.

"Aw, too bad. I liked you better when you were a walking griller.", Ben retorted only to earn a glare from Jen as she cleared her throat.

"What?", Ben puzzled.

"It won't come off.", Gwen grunted, still trying to get the Omnitrix off.

"Better not fool with it anymore until we know exactly what we're dealing with. I'll go check out that crash site. You guys stay here until I get back.", Max suggested.

Back in space, a pod shot down from Vilgax's ship above orbit, hurdling down to deep in the woods. Revealing itself as a gigantic robotic drone, it disintegrated the pod in the crash site, and shot out two smaller flying drones from its shoulders to find the watches.

Meanwhile, Gwen and Jen were examining the Omnitrixes on the back of the Rust Bucket.

"I wonder what else it can do.", Gwen puzzled.

Then, Ben surprised Gwen and Jen.

"Caught ya!", Ben shouted before laughing before Gwen mimicked Ben's laughing.

"Very funny, like your face.", Gwen retorted.

"Look. I want to find out more about it as much as the next guy, but Grandpa told us not to mess with those things.", Jen responded.

"Yeah? So? What's your point?", Ben asked.

"Your parents drop you when you were a baby?", Gwen asked.

"Come on. You can't tell me you aren't a little bit curious what else this thing can do?", Ben asked.

"Not in the least.", Gwen responded.

"You sure you're related to me?", Ben asked.

Meanwhile, Max observed the crash site as he picked up a small piece of metal debris.

"I don't like this one little bit.", Max spoke.

At the campfire, Ben was curious about how it felt for Gwen and Jen.

"So, how did it feel going all alien like that?", Ben asked.

"It freaked us both out at first. It was like we were us, but it was also like we were...somebody else.", Gwen responded before she and Jen both pressed buttons beneath the Omnitrixes, causing them to pop up, showing different silhouettes.

"Okay. I'm still not use to that.", Gwen commented.

"Well, maybe it takes time getting use to?", Jen guessed as she turned the dial on her omnitrix.

"Maybe. Anyway, let's give this another shot.", Gwen suggested as she turned the dial on her omnitrix as well.

"After you.", Jen responded before she and Gwen activated the Omnitrixes and found themselves transforming into Wildcat as Gwen's eyes turned pink with cat slots before her skin turned pink and sprouted fur on the arms and legs while her ears grew pointy and her teeth sharp while a pink tiger-like tail grew from her butt before she posed with her claws on the ground.

"Meow.", Wildcat smirked.

As for Jen, her skin turned pale blue before her clothes turned into that of a magical christmas-tree-like dress and shrunk down while also sprouting wings. When the changes were complete, the pink and green lights faded to show their new forms.

"Aw, man! Talk about a major catscratch.", Ben commented.

"I know, right?", Wildcat responded with a grin as Pixie Wish flew over to Ben.

"How do I look?", Pixie Wish asked.

"Aw, you look so cute, I could just squeeze you tight.", Ben spoke in a slightly mocking tone.

"You mean in a good way or a bad way?", Pixie Wish asked, making Ben widen his eyes.

"Come on. I didn't mean it like that.", Ben responded before noticing a water bottle nearby and giving a smirk.

"Ben? What are you doing?", Pixie Wish asked before Ben picked it up and prepared to splash Wildcat only for her to sense it, and dodge by jumping onto the top of the RV, causing it to splash on the dirt on the ground instead.

"Hey! You didn't tell me that alien could jump that high!", Ben exclaimed before Wildcat leapt off and landed on her own feet in front of Ben.

"Good thing a cat always lands on her feet.", Wildcat smirked before she turned around and kicked some dirt at Ben and leapt away.

"I've always wanted to do that ever since you brought Renee into this!", Wildcat smirked as she leapt away.

"Gwen! Come back!", Pixie Wish shouted before sighing.

"I'd better go get her before she goes too far away.", Pixie Wish spoke before flying off after her.

"Okay, this is a majorly weird day.", Ben commented.

Meanwhile, Wildcat swung across from tree to tree before coming across one of Vilgax's drones, sensing it before it can shoot her down and leapt away just before Pixie Wish caught up.

"There you are, Gwen! I don't know why you ran off like that, again, but...", Pixie Wish spoke before Wildcat interrupted.

"Quiet. There's a drone here.", Wildcat whispered.

"Where?", Pixie Wish asked before Wildcat pointed to it nearby.

"Oh. So, I guess we have to smash it apart, right?", Pixie Wish asked.

"Yeah. I could use some target practice anyway.", Wildcat responded.

"I'll see what I can do to keep it in one place.", Pixie Wish assured before she flew off, circled around behind the drone, and suddenly blew the drone back as air came out of her hands.

"Whoa! I did not know this alien could do that.", Pixie Wish spoke in awe before the drone recovered and moved in toward her only to be blown away again, this time to a point where the drone is stuck in a constant place.

"Now, Gwen!", Pixie Wish shouted before Wildcat snuck up and destroyed the drone, ripping it to pieces.

Just then, both Gwen and Jen timed back into their human forms, happy to have destroyed it.

"Yes!", Gwen and Jen cheered.

However, a second drone arrived, looking down at them.

"Uh-oh. Not good...", Gwen spoke.

Act IV

As the drone had Gwen and Jen in its sights, Ben came along and smashed it with a shovel, saving them.

"Ugh! Back off, sparky! No flying tree-trimmer is going to hurt my sister or my cousin!", Ben shouted as he hit the drone several more times.

"Never thought I'd say this, but, boy, am I glad to see you.", Gwen grinned.

Then, the Drone got set on fire as Ben, Gwen, and Jen ran away before it exploded.

Later, the Tennysons were sitting in the RV as Max scolded Gwen and Jen for their behavior.

"I was worried that you two might get popular with those things on your wrist. That's why I asked you not to fool around with them until we know what the heck they are.", Max responded.

"Sorry, Grandpa... But at least we figured out how to make it work.", Gwen responded.

"Yeah. All you do is press this button. Then, when the ring pops up, just twist it until you see the alien you wanna be. Slam it down, and presto! You're one of ten super-cool alien heroes!", Jen grinned.

"All right. I guess it's cool? But what about staying a super-cool alien hero and not changing back?", Ben asked.

"We kinda haven't figured that part out yet.", Jen responded.

"With a device as powerful as those watches clamped on you two, my guess is we better help you learn… fast.", Max suggested, slightly surprising the girls as Ben got excited.

"Alright!", Ben grinned.

Suddenly, a distress call sounded on the radio.

"Mayday! Mayday! Somebody help us! We're under attack by some sort of; I know you're not going to believe me, but… robot!", the ranger shouted.

"Sounds just like those things that attacked us. They must've been looking for the watches. Those people are in trouble because of us! We have to go help them.", Gwen urged.

"But how are you going to take care of those drones?", Ben asked.

"Did you forget, dweeb?", Gwen responded as she gestured to her Omnitrix as Jen gestured to hers.

Outside, Ben, Gwen, Jen, and Max went into the woods before Gwen and Jen turned to Max, who gave the green light with a nod before both Gwen and Jen activated their omnitrixes and started turning the Omnitrix dials, skipping over the silhouettes of Ghostfreak and Stinkfly before stopping at a silhouette of a being made of crystal.

"Yeah. Eenie, meany, miney…", Gwen spoke was she and Jen did so.

"Here goes!", Jen responded before she and Gwen pressed the Omnitrixes down both and transformed into diamond-like beings as they were covered from head to toe in crystal before spikes formed on their backs.

"Wow. Shiny. So what can this guy do?", Ben asked.

"I don't know, but I bet it's gonna be cool.", Gwen responded as she clenched her fingers.

"I call dibs on calling her Crystalstrike.", Crystalstrike shouted.

"Oh, man. I guess I'm sticking with Diamondhead.", Diamondhead sighed.

Meanwhile, Vilgax's gigantic drone was attacking a campsite full of RVs.

"Looks like papa robot this time. Jen and I'll get gear-head's attention, you guys get the campers to safety.", Crystalstrike urged before Ben and Max ran off with Crystalstrike and Diamondhead resolving to run toward the giant robot as it grabbed park ranger.

"Leave him alone! You want someone to pick on? Try us.", Crystalstrike spoke up as they were scanned before Crystalstrike was blown away by the giant robot's blast and crashed with a nearby truck and got out from the pile by his sharpened arm and examined it.

"Cool...", Crystalstrike grinned before she then gets up and charges after the robot only for it to jump up, spin its legs, and trap her under its legs.

"Uh-oh, think I'm in trouble.", Crystalstrike spoke.

Meanwhile, Max and Ben saved the ranger.

"What is going on here?", the ranger asked as Crystalstrike fought the drone.

"You probably wouldn't believe me even if I told you. Now come on.", Ben urged.

The ranger, however, hesitated as Ben and Max ran off, but ran once the giant robot threw Crystalstrike into his truck, just barely missing him.

During the fight, a stray projectile knocked a tree, and as it was about to hit Ben, Diamondhead was able to block it, by splintering it in twain with a spike pertruding out of her back, before the spike went back into her.

"So? We even?", Diamondhead asked.

"Even.", Ben nodded just before the robot grabbed a hold of Diamondhead's arm.

"Uh oh!", Diamondhead spoke before the robot lifted her up as the alien struggled for a moment before and destroying the robot's hand, causing it to toss her across the site into storage.

"Jen!", Max shouted.

After that, Crystalstrike ran to Diamondhead and helped her up.

"You okay?", Crystalstrike asked.

"Barely. Let's try it again, though.", Diamondhead responded before they ran toward the robot just as it fired a laser shot at them.

After unsuccessfully blocking the laser shot at them, Crystalstrike and Diamondhead were knocked down. Then, the former got an idea as she looked at her spiked arm.

"Of course. The power of refraction.", Gwen spoke before she got up and ran closer to the robot as Diamondhead understood where she was going.

"Oh. I get it now.", Diamondhead grinned before she got back up and caught up as well.

"Let's go, ugly! Hit us with your best shot!", Crystalstrike goaded before the robot took aim.

"Get out of there. Run!", Max shouted.

"Don't worry. They've got it, Grandpa.", Ben assured.

Then, the laser was shot at the two aliens before Crystalstrike and Diamondhead then managed to stop the laser and hold it back.

"What comes around goes around.", Crystalstrike spoke.

"Let's see how you like it, ya techno-freak!", Diamondhead added before they both completely sent the robot flying up by its own laser and cut it in half as a result, destroying it.

"Alright!", Ben and Max shouted.

"All right! Who's next?", Crystalstrike spoke.

"Well..., I think our work here is done.", Diamondhead spoke before she and Crystalstrike Jaunted away.

"What are those things?", the camper asked.

"They're no things! They're my granddaughters.", Max responded.

Meanwhile, Vilgax found out the failure to retrieve the Omnitrixes.

"Failure?! Unbelievable! The puny Earth beings that are keeping the Omnitrix from me will soon hang on my trophy wall!", Vilgax growled.

Back on Earth, Ben and Max were packing up.

"Where're Gwen and Jen?", Max puzzled.

"Don't know. I haven't seen 'em since breakfast.", Ben responded.

Then, XLR8 arrived back to the Rust Bucket.

"Jen?", Max asked before XLR8's visor went up.

"Yup.", XLR8 responded.

"Where's Gwen?", Ben asked.

"See for yourself.", XLR8 responded, pointing to Gwen, who was popping out from her own laptop inside the RV in her new alien form known as Digit.

"I just tripled my laptop's processing speed!", Digit spoke excitedly before timing out.

"And that's not all. Check this out!", XLR8 added before she used her newfound super-speed to break camp and pack the baggage in record time.

"Pretty fast, huh?", XLR8 spoke before her Omnitrix timed out, changing her back to Jen.

"I think this is gonna be the best summer ever.", Jen grinned.

"Absolutely.", Max agreed.

"It's definitely going to be interesting.", Gwen agreed.

"So, where'd you go anyway?", Ben asked.

"Well, I just had to take care of a couple of things before our vacation really got rolling.", Jen responded.

"Like what?", Ben puzzled.

"Well, you'd be surprised.", Jen smirked in response.

Meanwhile, Cash and J.T. were hanging down on a tree by their underwear.
