A/N: Hello. I managed to finish the next chapter of Gwen 10: The Celestial Twins, this time, introducing a few new aliens, one of which was used by Jake H Voronkov, who gets the credit for it. :) Anyhoo, enjoy.

Gwen 10: The Celestial Twins

Washington B.C.

Act I

It all started with the sirens blaring while in the middle of the city, a building is engulfed in flames. Inside the house, a boy and his mother were trapped between flames as the ceiling of the room began to cave in. The young boy shut his eyes as debris fell from the roof looking like it'll collapse, but opened them when he found himself saved and Pyroflow holding up the roof.

"Who are you?", the boy inquired before Pyroflow grunted, moving the debris off herself.

"I'm here to help.", Pyroflow assured before she then absorbed flames around and lead the two to the stairs.

"This way.", Pyroflow urged right before the stairs collapsed.

"Uh, on second thought...", Pyroflow spoke before noticing a window nearby.

"That way.", Pyroflow spoke before she saved the boy and his mother by transporting them through the blasted out window in a bubble of fire as the crow let out awed gasps.

"I'm sure you all want to thank me personally, but really, it's all in a day's work for a hero.", Pyroflow spoke.

"You could say that again.", Flash Flood concurred as she walked forward and fired water from her hands to put out the fire in and out of the building just as the Rust Bucket pulled out and beeped urgently, catching the alien duo's attention just as Flash Flood finished putting out the fire.

"Yo, Jen! Super-Dweeb! The fire was just a diversion to cover up a jewellery store robbery. The bad guys are getting away!", Ben shouted.

"Not for long, they aren't.", Pyroflow smirked in response before creating a podium for herself to ride on and taking off.

Act II

Later, Max was in the midst of a car chase with the jewellery thieves, in the Rust Bucket as Pyroflow flew by the RV before Flash Flood fired her water blasts at the windshield, making it so they couldn't see.

"What the heck?! I can't see nothin'!", the robber exclaimed just as Pyroflow caught up and aimed at the car before shooting a ball of fire toward it and hit below the car.

"Str-rike!", Pyroflow smirked before the first robber screamed as their car crashed into a wall.

Then, Flash Flood unfastened her seatbelt and got out of the Rust Bucket before she spoke as Pyroflow bent the car door.

"Unless you guys want a permanent sunburn, I'd suggest you put your hands against the wall.", Flash Flood advised before the robbers walked out of the car and did as instructed.

"You punks just picked the wrong day to be bad guys.", Pyroflow spoke just as the police arrived, surrounding them all.

"Freeze!", the officer shouted, pointing his gun at the thieves.

"They're all yours, officers.", Pyroflow grinned.

"I know you all want to thank us, but we gotta go.", Flash Flood added as their emblems beeped and flashed before they took off and hid behind the rust bucket and timed out, reverting back to normal form before Gwen and Jen walked back into the Rust Bucket.

Later, Roger knocked at the door, with the sign labelled "Dr. Animo" hanging outside.

"Yo! Animo! I know you're in there. Open up!", Roger shouted before he snuck in coming across all the lab equipment and experiments stocking the shelves.)

"Phew! Smells like a zoo in here.", Roger commented before he became startled upon seeing Animo sneaking up behind him.

"How did you get in?", Dr. Animo asked angrily.

"Pass-key. I am still your landlord, remember? Maybe not, since your rent is six months pass due.", Roger explained as he adjusted his tie.

"All my funds go into my research. Now get out! You're disturbing me.", Dr. Animo demanded before Roger looked around.

"Hmm. Looks like you were disturbed long before I got here, pal. Listen, Doc', you and your furry friends are out on a street unless you pony up the green.", Roger spoke, giving Dr. Animo a wonderful, awful idea as he smirked.

"Pony up... Interesting choice of phrases... You must be an animal lover. Then you're gonna love this.", Dr. Animo responded as he picked up a frog from one of the tanks and put on his Transmodulator helmet.

Roger only paused before he began laughing mockingly.

"What's that? 'You a member of the moose lodge or something?", Roger asked mockingly.

"This is my Transmodulator. Phase number one: it creates and accelerates mutations at the genetic level. Observe:", Dr. Animo explained as he twisted a button on his chest, activating the Transmodulator before beams shot out and down from the horns of his helmet, mutating the frog on the floor into a gigantic version of itself.

Roger looked up at the frog and screamed as the frog opened its mouth and engulfed him.

"I'm sorry! -I can't hear you. It sounds like you have a frog in your throat. Ah-ha-ha-ha-ha! Or is that the other way around?", Dr. Animo joked before laughing maniacally and the frog spat out Roger, who moaned and passed out.

"So-oo- close to having, what is rightfully mine. All I need is a few lousy components to finish my work!", Dr. Animo grinned before he overheard the announcer in the TV set from the Mega Mary commercial.

"So, whether you're in need from hair spray to state-of-the-art electronics, you'll find them under one roof at the grand opening of the district's newest Mega Mart!", the TV announcer assured.

"Ahh! Just what the doctor ordered.", Dr. Animo grinned.

Meanwhile, Gwen, Jen, Max, and Ben were at the M-Mart, walking down several aisles at once as at one of them, Ben found the cereal ("Sumo-Smacks") with Sumo Slammer cards inside.

"'Sumo-Slammer cards', cool!", Ben grinned excitedly as elsewhere, Gwen was browsing for a few books in one aisle and Jen was searching through a few musical movies in another while Max picked up a canned octopus.

"Only canned octopus? I thought this store prided itself on wide selection.", Max commented.

"Well, it's probably for the best. I don't mean to be hurtful, but I don't think anyone in their right mind would eat that, anyway.", the man spoke as he turned up closer.

"Hah. Nonsense.", Max retorted before he got a better look at the man and widened his eyes.

"Daniel?", Max puzzled.

"Max! Man, are you a sight for sore eyes!", Daniel grinned.

"I haven't seen you in 11 years, Dan. How've you been?", Max asked with a light chuckle.

"You kidding? I was about to ask you that.", Daniel grinned.

"Oh. I have a few people I want to show you.", Max grinned.

"Really? Well, show me.", Daniel grinned.

Later, Daniel was brought before Ben, Gwen, and Jen.

"You know this guy, Grandpa?", Gwen asked.

"Yep. This is an old friend of mine. We go way back.", Max responded.

"No way. That guy is your buddy?", Ben puzzled.

"You bet. Daniel's the name, having fun's my game. But you can call me Dan.", Daniel greeted.

"Hi, Dan. I'm Jen. And the kid snooping around in the cereal aisle is my brother, Ben, and this is my cousin, Gwen.", Jen introduced.

"Nice to meet you, Dan.", Gwen grinned.

"Nice to meet you, too, Gwen.", Daniel responded.

Then, all of a sudden, shops began to rumble as TV sets fell from their displays, and the walls burst revealing Dr. Animo mounted on his giant frog.

"Whoa.", Ben spoke in surprise upon noticing Animo getting down from the frog and beginning to start pick-pocketing the electronics.

"Hey, what do you think you're doing?", Ben asked before the giant frog then used its tongue to knock stacked boxes on top of Ben.

"Ben!", Jen exclaimed before running toward him to help him up as Ben got up himself.

"Are you okay?", Jen asked.

"Yeah. I think so.", Ben responded just as the security guards ran up to Animo.

"Freeze!", the 1st security guard exclaimed.

"Get down off that giant... frog and put your hands up.", the 2nd guard added bewilderingly.

"Don't be a hero, kids. Just run along and play.", Dr. Animo spoke before riding away, leaving Jen giving a sour look toward him.

"Uh, we got a grab-and-dash in Electronics. Male, five-foot-six, riding on a giant frog - or a toad. Trust me, you can't miss him.", the 2nd Guard spoke time his walkie-talkie.

"It looks like he's headed toward the pet aisle.", Max spoke.

"All right, that's it! First, he steals the technology, then he tried to hurt Ben, and now this?! No one pushes my brother around like that and gets away with it!", Jen glared as she activated her Omnitrix.

"You got that right. Only I can do that.", Gwen agreed as she activated hers before both pressed the dials down and transformed.

While Gwen became Wildcat, Jen became a more doglike version alongside her.

"Looks like this poacher's about to get nabbed.", Wildcat hissed before she and Wildmutt ran off after Animo, puzzling Daniel.

"Is that...?", Daniel whispered.

"Oh, yeah.", Max responded before Daniel gasped in shock.

Meanwhile, Animo shot a beam toward a hamster and a Cockatiel, mutating then.

"Arise to your full potential, my pets!", Dr. Animo shouted before Wildcat and Wildmutt ran to the scene and saw the mutated hamster chasing a couple of customers away.

"Geez! What kind of pet food are they selling around here?", Wildmutt asked.

Act III

Dr. Animo showed his mutated animals, all aligned next to him.

"Behold the genius of Dr. Animo. Nothing can stop me from getting what I deserve. Mark my words! Today I will make history, or- should I say...pre-history!", Dr. Animo declared.

The hamster roared as it took a step forward before then trying to chomp on Wildcat only for her to leap up to avoid the chimps three times before scratching it in the nose, making it squeal in pain.

"Hah! Didn't like that, did you?", Wildcat smirked before the hamster only roared angrily at her in response, making her drop her ears down in fear as she gulped.

"I guess I'll take that as a 'no'.", Wildcat spoke nervously before the football was tossed at the hamster, who promptly turned to notice Wildmutt, who was the one who tossed it.

"I hear fetch is a good game. Wanna try it with me?", Wildmutt goaded before taking off, prompting the hamster to run after her.

When it did, Wildmutt led the hamster to the middle of the aisle before leaping up and tipping the other aisles down toward it, trapping it.

"Yes! Got it!", Wildmutt grinned as Wildcat caught up.

"Good thinking. That should keep it still for now.", Wildcat grinned as the hamster tired out before Max and Daniel caught up and saw Wildcat and Wildmutt each giving a thumbs-up.

"Cleanup aisle six.", the employee spoke over the intercom.

Suddenly, Dr. Animo spoke up as the fire hopped toward Wildcat, Wildmutt, Ben, Max, and Daniel.

"Fools! You cannot stop me! I will turn 'Washington D.C.' into 'Washington B.C.'!", Animo swore before jumping from his frog to the mutated parrot, who flew off with him through a sky light, with the frog following.

"Something tells me it's gonna take a while to get used to it.", Daniel spoke before Gwen and Jen reverted back to normal as soon as their omnitrixes timed out.

Then, the Store Manager walked up toward Gwen and Jen.

"You two saved the store! If there's anything I can do to repay you... anything you want.", the store manager spoke.

"Well, I guess, now that you mention it...", the girls spoke in unison, motioning to the books and movies nearby.

Later, Max and Daniel were chasing down Dr. Animo's parrot in their vehicles.

"Ah, just like the good old days... before I retired.", Max reminisced.

"So, exactly, what kind of plumber were you, Grandpa?", Gwen, who was now back to normal, asked.

"Not a good idea to tell them now, Max.", Daniel whispered.

"Uh- yuh-, a darn good one.", Max responded nervously before noticing Ben looking down.

"Uh, Ben, what's the matter?", Max asked.

"They saved an entire Mega-Mart from being a giant hamster's chew toy, and they got free books and movies. It's not fair.", Ben responded.

"Being a hero isn't about others knowing you did something good, it's about YOU knowing you did something good. They only got those because they earned it for helping people. Being a hero is its own reward.", Max responded.

"What? Were you reading the greeting cards at the Mega-Mart?", Ben asked.

"Well, yes.", Max responded.

"Right. So, anyway, any info about Animo so far?", Jen asked before Gwen gasped in response.

"Bingo! Five years ago, Dr. Animo was a promising researcher in veterinary science. But it turned out he was doing all these twisted genetic experiments where he was mutating animals, and when he didn't win some big prize called the Verities Award, he flipped out.", Gwen responded before glaring toward Ben.

"Anything about this sound familiar, Ben?", Gwen asked to Ben, who just looked out the window just as Max and Daniel lost sight of the parrot.

"We've lost him. He could be going anywhere in Washington D.C.", the latter spoke.

"Or Washington B.C.", Gwen spoke before Ben gasped in realization.

"That's it! I know where he's going: the Natural History Museum.", Ben realized.

Later, upon arrival, he found a giant feather at the stairs to the museum.

"Something tells me we're on the right track. Good thinking, Ben.", Max spoke.

"Yeah. Who knew you'd actually guess where he's headed?", Jen added.

"Guess even a doofus can surprise you once in a while.", Gwen grinned.

"And you should know.", Ben responded.

While walking, Ben and the others noticed a part of the Mega Mart electronics, with Daniel and the Tennysons coming across Dr. Animo.

"You... are very persistent. I hate persistent.", Dr. Animo glared.

"We all know about you and your genetic experiments, Dr. Animo. It's over.", Gwen discouraged.

"Oh, but it's only just begun. See, I only needed a few components to push my work into phase two: The re-animation of dormant cells.", Dr. Animo retorted.

"Uhh... Does this guy come with subtitles?", Ben asked confusedly.

"Breathing life back into that which has been long since lifeless. Observe.", Dr. Animo explained before shooting a beam, re-animating a mammoth on display in the process.

"Behold the genius that is Dr. Animo!", Dr. Animo proclaimed before running away.

"It would be a really good time to go hero right about now...", Ben urged.

"No duh.", Gwen retorted.

"You guys get Animo. Gwen and I'll take care of Jumbo.", Jen added before they both activated their omnitrixes and pressed them down with veins coursing down Gwen and Jen's arms before they opened their blank orange eyes, grew muscles, as well as two additional arms each, and transformed into red, four-armed aliens.

When the lights dimmed, Ben, Max, and Daniel gasped.

"Whoa. Now, that looks awesome.", Gwen spoke in a slightly deeper voice.

"Yeah. I can see that. These guys probably need a name, though. Hmm. Oh! How about Four Arms?", Four Arms asked.

"All right, but only if I get to call this alien CrimsonFist.", CrimsonFist responded.

"Deal.", Four Arms agreed as she and CrimsonFist shook on it.

"Okay. Let's wrestle!", CrimsonFist shouted before running toward the mammoth.

Meanwhile, Max and Ben came across the giant parrot, with Ben picking up a spear from a caveman display and scaring it off as he poked it until it ran away.

"Phew. I did not think that was gonna work.", Ben sighed.

Then, Ben and Max caught up to Animo, who smiled before re-animating a Tyrannosaurus Rex.

Meanwhile, the mammoth threw Four Arms into a wall near CrimsonFist.

"Okay. That hurt a bit less than I expected.", Four Arms commented before the mammoth then proceeded to charge at her again.

"You're going down, peanuts.", CrimsonFist spoke before she grabbed a hold of the mammoth by the tusks before it could ram into Four Arms and spun him into a wall adjacent to Four Arms, defeating it.

"Phew. I guess that took care of him.", Four Arms sighed before noticing CrimsonFist looking dizzy.

"Are you okay, Gwen?", Four Arms asked.

"Ohh... So dizzy...", CrimsonFist moaned.

"Maybe you should take it easy for a while.", Four Arms suggested.

Meanwhile, Dr. Animo fled on the back of the T-Rex, almost hitting Max, Daniel, and Ben with a whack of its tail.

"I'd love to stay, but I need to claim the award I so richly deserve.", Dr. Animo spoke.

Suddenly, the parrot swooped down and grabbed Ben, who gasped and screamed.

"Ben!", Max shouted.

Then, Four Arms and CrimsonFist saw Ben in the parrot's talons before leaping over Max to chase after them just as Daniel bent down, picking up a photograph.

Once in the air, Four Arms and CrimsonFist grabbed a hold of the parrot by the wings.

"No bye-bye for you.", CrimsonFist discouraged before the feathers they were holding onto plucked out, sending them falling to the ground before they crash-landed and transformed back to Gwen and Jen before climbing out from the crater and could only look on as the parrot carried Ben away.

"BEN!", Gwen and Jen shouted in unison.

Act IV

Gwen and Jen could only watch as Ben was carried away when Max and Daniel drove up.

"Somebody call for a taxi?", Max asked with a smirk.

Meanwhile, the parrot was carrying Ben by his shoulders toward the Washington Monument.

"First, I'm stuck with a dweeb for my summer vacation and now this?", Ben spoke dourly.

Meanwhile, on the ground below, Animo on the T-Rex crushed a building, not knowing that a golden Sumo Slammer Card was lodged in one of the dinosaur's toes.

"Ah, I do love my work.", Animo grinned.

Meanwhile, Gwen and Jen were looking out for the mutated parrot.

"No sign of beak-breath!", Jen spoke.

"There can't be that many places for the parrot the size of an elephant to roost.", Max responded before Daniel handed over a piece of paper to Gwen and Jen.

"Here, look at what Dr. Animo left behind.", Daniel spoke.

"'Dr. Kelly accepts Verities Award.'", Gwen read before she spoke to Max.

"He's on his way to pick up his award!", Gwen spoke.

"We have to stop him!", Jen urged.

"First things first. We have to find your brother.", Max responded just before Ben shouted.

"HELP!", Ben shouted.

"Ben!", Max, Daniel, Gwen, and Jen shouted.

"Hang on, Ben, we're coming!", Daniel shouted.

Meanwhile, the mutated parrot left Ben, barely holding on the top spike of the monument.

"I can't hold on much longer.", Ben spoke worriedly.

"Oh no. If we don't do something soon, he could end up pancaked!", Daniel spoke in worry before Gwen and Jen noticed that the cool down on their omnitrixes wore off.

"Not if we can help it, he won't.", Gwen smirked before she and Jen activated and pressed their omnitrixes down.

When they did, a pink, goo-like liquid emerged from her Omnitrix and coated Gwen's body all over, leaving her worried, if not disgusted before a blue wrapping emerged from below, wrapped her up completely, and hardened before being broken apart as when it did, she now has a slender, humanoid body, which is mostly blue, with a more circular head while her shoulders, armpits and ankles are light blue and her chest, abdomen, neck, and the lower part of her face are cyan with three blue fingers on each of her hands and three-toed dark cyan feet, with the third toe being on the back of her feet; she also has light pink eyes and a light blue V stripe on her forehead, one coming from each eye, one on his nape, and one in each finger and two in her thighs with two orange wings with black edges and two dark cyan antennae and four insect-like flat legs.

As for Jen, her body morphed into that of a humanoid firefly as the badge now rested on her stomach. After the transformations, the girls took flight.

Just then, Ben finally slipped and fell with a scream just before Gwen swooped in and grabbed him.

"Gotcha!", Gwen spoke.

"Huh?", Ben puzzled before looking at Gwen and Jen, surprised.

"You okay, Ben?", Jen asked.

"Stinkfly! And Firefly!", Ben spoke.

"Actually, I'm Butterfly!", Butterfly retorted while looking back at Ben.

"You got the Firefly part right, though.", Firefly assured.

"Yeah, whatever. Anyway, thanks for the save.", Ben thanked before seeing the giant parrot and gasped.

"Incoming!", Ben shouted.

"Hang on!", Firefly urged before she and Butterfly started flying faster.

Meanwhile, Max and Daniel saw the battle in the air and ran to the monument just as Firefly noticed. Ben yelped as he hung onto Butterfly's back as best he could.

"Whoa! What big nails you have, Polly!", Butterfly commented.

"Oh, I think I'm, gonna be sick.", Ben groaned.

"Hey. You spew on me, and you'd better learn to fly, quick.", Butterfly warned as she and Firefly continued trying to evade the mutant parrot.

Meanwhile, Max and Daniel were getting exhausted from walking up the Washington Monument.

"Ugh...! Why...are there...so many...stairs?!", Daniel panted.

"Like it would've killed the founding fathers to install an elevator...", Max agreed with a pant before Butterfly and Firefly noticed Max and Daniel gesturing to them from the monument.

"We can't shake that bird off. You're gonna have to trust us.", Butterfly spoke.

"What do you mean?", Ben puzzled before screaming as Butterfly dropped him off from her back and then grabbed him by her hands, flying toward the Washington Monument.

"Hope you're ready, Grandpa!", Firefly spoke.

"Now!", Butterfly added before she got Ben in Max's arms.

As Max was dragging Ben back into the building, the mutated parrot dove toward them, only to get knocked from its course by Firefly's shoulder barging it down.

"Go! Stop Animo. We're all right.", Daniel assured.

"Speak for yourself.", Ben groaned.

Then, Butterfly and Firefly nodded before flying off after Animo.

Meanwhile, Dr. Kelly was showing his reward to the tour group of VIPs.

"And here is my Verities Award. Of course, it was an honor just to be nominated with a distinguished group of scientists...", Dr. Jelly began before Dr. Animo and the T-Rex suddenly smashed through a glass wall to invade to Dr. Kelly's company.

"Kelly! I believe you have something of mine.", Animo glared before he jumped down and grabbed the Verities Award.

"I'd like to thank the committee for this honor.", Dr. Animo spoke.

Then, the T-Rex roared, swiping its mouth toward Kelly only for Butterfly to rush in and ram it in the face before any damage can be done only to get quickly swiped by its tail.

"Geez. This hero business isn't easy.", Butterfly groaned just as Firefly spotted a golden Sumo Slammer Card.

"Huh? What's that card doing here?", Firefly puzzled.

"Somebody help me!", Dr. Kelly screamed as the T-Rex prepared to eat him.

"You go on ahead! I'll catch up.", Firefly urged before Butterfly nodded and charged in toward Dr. Kelly just as Firefly managed to pick up the card before the debris could collapse on it.

Then, Dr. Kelly screamed while falling toward the dinosaur's mouth before he was saved in the nick of time by Butterfly.

"What are you, you little pests?", Dr. Animo asked as Butterfly landed.

"I'm Butterfly, she's Firefly, and we're here to kick some tail!", Butterfly responded before Dr. Animo shot the beam at the two bug-like aliens, who dodged and knocked him off, making him drop the award before it shattered into pieces.

"No!", Animo exclaimed before Butterfly tapped his shoulder and stole the Transmodulator.

"My Transmodulator!", Animo exclaimed.

"You're right about one thing, there's no stopping you from getting what you deserve!", Butterfly spike before she broke the Transmodulator, causing the T-Rex to de-animate back into bones, causing Animo to fall to the ground.

"No...! No...! No!", Animo exclaimed.

Meanwhile, the mutant parrot was approaching Ben, Daniel, and Max when it suddenly turned back to normal size and perched on Ben's arm.

"Oh, no. Don't even try to kiss up to me now.", Ben commented.

Later that morning, the police arrested Dr. Animo at Dr. Kelly's workplace.

"Let me go! I deserve that award! I've got it coming to me! I want it!", Animo exclaimed as he was being promptly arrested.

"Why don't you just grow up already?", Jen asked in response.

Later, both Daniel's car and the Rust Bucket left Washington D.C.

"You doing okay, Ben?", Jen asked.

"Yeah. I didn't get that gold Sumo Slammer card, but you and Gwen saved me before stopping Animo. Like real heroes.", Ben responded.

"But that's not all.", Jen responded before getting out a golden Sumo Slammer Card, surprising Ben.

"No way! You found a golden Sumo Slammer Card?! Where'd you find it? How did you find it?", Ben asked.

"I found it during our fight against Animo last night. I had to hold onto it until we took care of Animo first, though.", Jen responded.

"Whoa. Thanks.", Ben thanked.

"Yeah, well, that's what we heroes do best. Next to rescuing dorks, of course.", Gwen grinned.

"You are...such...a major dweeb.", Ben responded with a slight grin.

"I know you are, but what am I?", Gwen retorted with a giggle.

A/N: So, what do you think? Pretty great, right? Now, if you'll excuse me, I have a few episodes of "MLP" I gotta get to for Misako's sake. And also get ready for my Infinity Train/Glitch Techs crossover story later this Christmas in the meantime after pisting another episode of the Ben 10 Rewrite series. Until next time. :)
