At night in the forest by the lake, a few DNAliens walked into the forest to look for possible victims, being especially careful of what was going on as the leaves crunched under their feet, moving forwards with blasters in hand as they made a few clicking noises to one another.

Little did they know that a figure was watching in the tall grass beside them, stalking them like a predator to prey.

As they moved through the woods, a few vines burst out of the shadows and wrapped around its stomach and limbs, pulling him into the darkness of the forest.

"What was that?" one remaining DNAlien said to the other as roots suddenly grew from around its feet, pulling it down and out, dragging it into the forest with a shout as the remaining DNAlien looked to see a shadowy figure that resembled a plant-like teenage-girl in a dress with glowing golden eyes like pollen with green irises and black pupils glare at him.

"Can we talk about this?" he asked suddenly.

That was when the plant lady rose her two arms and two crystal-like structures grew from the ground, trapping the DNAlien where he stood, his weapon falling to the ground as the plant lady smiled and rose her hand up two Venus flytraps growing from the plants around her and hissing at the mutated abomination before her.

"I'm afraid not," she said as she shot her hand out and the Venus flytraps hissed before shooting for the alien, directly at the camera as it cuts to black.

Meanwhile, at the lake beside the woods, flashes of pink light came out at each other as Jen clashed mana staffs with Gwen, both wearing exercise attire as they both struggled in each other's grip as they dodged each other's swipes and Gwen tripped Jen up with a sweep kick, sending her sprawling to the ground as she came jumping towards her before the brunette blasted forth with a blast of mana that sent her cousin flying back before she screeched to a halt on her sneakers as she smiled and wiped her lip.

"Very good, Jennifer," Verdona said, watching from a far. "Gwendolyn, more ferocity next time."

"Yes, Grandma," the Anodite cousins said, bowing.

"Grandma," Jen said, stepping up. "Before you came, there's this group of heroes from all over the multiverse called the Protectors and they're very interested in me and Ben."

"Yeah. One of them is their guardian, the Scarlet Warrior," Gwen stated.

"I've heard of her."

"And a few years ago, an evil future version of myself talked about me being something called the Master..."

"The Master Spark," Verdona realized, smiling and laying a hand on Jen's shoulder. "An ancient evolved Anodite said to possess great power beyond that of an ordinary Anodite. To think my own granddaughter could be something that powerful at such a young age is beyond ridiculous... and impossible."

"Huh?" the girls asked.

"For you see, girls. The Master Spark is merely an old Anodite legend. A myth."

"It's not true?"

"Not a single word. Believe me."

That was when they heard a screech coming from the woods on the other side of the water and all heads turned to the source of the noise.

"Oh snap," Jen said as Verdona silenced her granddaughter with a wave of her hand and focused as her human form melted away to reveal the Anodite within, flying up.

"You two have done enough for tonight, girls. I will investigate this matter," Verdona said.

"We'll be here tomorrow," Gwen warned.

Verdona then flew over the woods, a small pink streak fading behind her as she looked over the path through the trees for any sign of damage... only to come up short. No burn marks in the grass or on the trees, no debris. Not a blade of grass was out of place there. Nothing.

"Strange," she said as she sighed and flew upwards. "Maybe it would be best if the kids take care of this. They're better at investigations than I am."

Becky stood at a table in the school mess hall, munching on her peanut butter and jelly sandwich with a sigh as she looked out to see Ben, Jen and Gwen walk by her table with a smile and sit down next to and beside her as she smiled.

"Hey, guys," she said as she fist-bumped her sister and the two sets of twin siblings unpacked their lunches and started talking with a smile.

"So, sis," Gwen said, taking a bite of her apple. "Anything interesting happen?"

"Oh, besides weekly patrols of the town and helping our friends out. Nothing. Not hide nor hair of the Highbreed or DNAliens that we've seen anyway. It's like they just vanished into thin air the minute Grandpa Max sacrificed himself."

"They're out there," Ben said as Jen looked on her phone of a video on the famous hero site the Miraculous Blog, looking at a video of the latest akuma attack in Paris.

"Jen?" Becky asked as she gasped and put her phone away.

"Oh, sorry. It's just that that Miraculous Team are such great heroes. They're every bit as famous in Paris as we are here," she smiled.

"Yeah, but they're only fighting to protect the Earth," Ben said, jabbing her arm. "We fight to save the Earth and the entire universe."

Jen rolled her eyes at that as she bit into her beef jerky. "Anyway, we were training with Grandma Verdona twice this week to make up for missing last week."

"Thanks, Emperor Milleous," Gwen sighed.

"And when we were sparring, Grandma noticed something... peculiar.'

"What?" Becky asked as she and Ben looked up.

"Well, we heard some distant screaming coming from the woods near the lake and Grandma flew over there to investigate," Gwen said. 'But when she came back, there was virtually no evidence to show that anything was there. Nothing."

"Are you sure you're not crazy?" Ben asked, sipping his cola.

"No, we're pretty sure," Jen said. "We know what we heard. Something's going on in those woods. And the Omni-Team is going to find out what. Tonight."

"Done," Becky said as they all put their hands in. "I'll text Allison and we'll get going to the woods tonight."

Meanwhile, a pale-skinned girl with hot pink hair sat in the corner, wearing a green shirt, red shorts and brown boots with a rose in her hair and green diamond earrings, supported by headphones in her ears playing music with a smile on her face as she sighed and ate at her baloney and cheese sandwich, smiling as the bell rang, signalling the end of the school day as she and the rest of the students stood up and left for their lockers, trying to get to the area as she went to get her stuff and smiled at her flora-covered locker with a smile as Becky stood by her at her own locker.

"Hi, Rosie," she said as the pink-haired girl looked to her and sighed.

"Hi, Becky," she said.

"So, me and my cousins are going to the woods tonight. What are you going to do?"

"Not much," she said. "Just gardening with my mom as always."

"Boring," Becky sighed. "I mean, I know flowers are your thing, but hey. Well, me and Gwen gotta get home. Bye."

Rosie sighed as she slung her backpack over her shoulder and her eyes briefly glowed their eerie green as she stepped away.

Rosie walked down the roads of the city with the music blasting in her ears as she kicked a can down the street before she looked up to her apartment building, with one area completely surrounded in vegetation and plants that grew from the walls. She stepped up to the floor of her apartment and pulled a key out of her pocket to reveal her Mom, who was clearly not human inside as she looked to see her daughter.

She was a Florian (the species of Blossom Rose), with a flower petal-like yellow dress, pale green skin and leaf flat shoes on her feet. She also had long stem-like hair tendrils with sunflower-like petals growing from it and pale yellow eyes with green pupils.

"Ma'Dow," she said "How was school?"

"Fine. Just fine," Rosie said as she reached on her neck and removed what was revealed to be an I.D. mask to show her true form: a Florian with a red flower-petal dress, leaf flat shoes, pale green skin and yellow eyes with green pupils, just like her mother. The only difference was her hair was in the form of a large rose flower growing from her head, similar to Blossom Rose.

"Is something wrong, sweetheart?" her mom asked.

"No, Mom. I just have a sickening feeling that I don't belong on this planet," she said. "I go to a school of humans when I'm not even a human myself."

"Well, we can't go back to Floria," she said. "And your father is out who knows where doing his work. But hey, there's lots of people like you out there. They don't know who they are either."

"Yeah, but it just feels awful to be viewed as an 'abomination' by your own people," she said as she sighed and generated a few crystals from her fingers before they sunk back in and she walked over to the flowers. "Sometimes I think the only friends I'll ever have are these guys right here."

She then tickled one in the bud and it giggled to her as she smiled and smelled in the pollen.

"What do you want for dinner tonight?" she asked.

"Beef stroganoff?"

"Sounds lovely," she said, kissing her daughter on the forehead before walking away.

"Those DNAliens are going to pay. In the name of nature, they will be destroyed!" she said, putting her I.D. mask back on and walking away.

Later that night, after parking the car and the motorcycle, the Omni-Team, clad in their super suits, walked on in the woods, illuminating the light with a pink mana ball as Omni-Green used his Omnitrix as a flashlight in the shape of the Omnitrix symbol.

"What is going on here?" Matter Girl asked, her eyes adjusting to the light.

"Craziness," Huntress said as she looked down and noticed the scattered weapons laying in the grass and she nodded. "There was clearly a fight involving DNAliens here. Or... I think it was a fight. It looks like they got slaughtered really bad."

"Yeah, well, whoever it was is clearly passionate about this forest," Gwen said.

"Or just nature in general," Omni-Green said as the team moved deeper into the forest, seeing green crystals sticking out of the wall. "Taydenite?"

"A Petrosapien who's defending nature?" Kevin asked, looking around. "Their planet was made of solid crystal. Why would one of them be defending a forest?"

"Maybe they're the self-appointed guardian?" Omni-Pink asked, shrugging, not noticing the pair of yellow eyes glaring in the background as she looked down and moved into the forest.

"Who knows?" Huntress said. "All I do know is that we're going to find out what's going on in these woods and fast."

As the team moved forwards into the woods, the Omni-Twins readied their watches as Omni-Green activated his energy swords and Omni-Pink and Lucky Girl gathered the mana around them as they looked forwards.

"Well, it's definitely a Petrosapien... I think," Lucky Girl said as they looked up to see a throne sculpted from solid Taydenite in front of them, gasping.

"You're partly right," said a voice from above and they gasped to see a vine stretch down from the trees above and saw who the audience knows as Rosie appear and sit on the throne with a smirk as they saw the creature appear and the plants around her moved, ready to attack as they gasped.

"Uh... hi," Omni-Green said as the plant creature above them smirked and smiled upon them. "We're here to investigate strange noises and fights going on in the wood."

"Well then stop looking," Rosie said. "Because I, Ma'Dow, am the one behind everything."

"Ma'Dow?" Kevin asked. "Like 'meadow?'"

"Yes. What's the problem with that?" she asked, stepping down from her throne and approaching them, the small flowers starting to bud behind her footsteps.

"Nothing. He's an idiot," Lucky Girl said, earning a glare from her as she looked to her. "What's with the DNAlien carnage?"

"Carnage?" Ma'Dow asked. "Oh don't worry. I haven't killed any of them... yet. I just had them sent to the Null Void using my equipment."

"Huh? You're a Plumber's Kid?" Matter Girl asked.

"Oh yeah. I've heard about you, Omni-Team. I've heard about how good you are from the cosmos. I want to see if they're right."

"We are."

"Let's test that, shall we?" Rosie said as she shot her hands out and several green crystals embedded into the trees behind them and they looked out with a gasp.

"We weren't exactly wrong about the Petrosapien thing," Huntress panted as she shot a few arrows at the Florian-Petrosapien hybrid as she shouted out and ran forwards, dodging the arrows as she grew two crystal blades from her arms and started engaging in hand to hand, the human dodging every blow with her quick moves before jumping up and giving a roundhouse kick to the face, sending her flying back with a smile as she rubbed her lip with a smile, a few drops of green blood mixed with chlorophyll dripping out.

She looked upwards to see Lucky Girl come in, eyes glowing pink as she sent out mana bolt after mana bolt to her opponent, who erected a wall of vines in front of her to block every shot that came at her, thorns flying away before she sent a flurry of thorns and crystals flying out.

Lucky Girl gasped as she blocked the shots with an energy shield and shouted out at the onslaught as a flash of green light appeared behind her and Ben appeared as...

"Big Chill!"

He flew around his opponent as he went intangible and phased through the crystals that were blasted out at him as he flew forwards and phased through the flower girl who almost instantly froze in place in front of him as he smirked, sub-zero air phasing through his lips before a few large roots burst through the ground and squeezed the heck out of the ice, breaking it and she sent a hand out to send the roots around Big Chill, surprising him as he flew to the ground.

Kevin shrugged as he stepped forward and sighed.

"Sorry. I don't like hitting girls," he shrugged.

"Kevin!" Lucky Girl shouted.

"Then this should be easy," she said as she shot her hand out and sent a cloud of blue pollen from her pores at him and he inhaled them and gasped, his eyes rolling back in his head as he hit the floor, falling asleep on the ground with Lucky Girl running to him as Jen ran forwards and transformed into...

"Jetray!" she shouted, spiraling upwards and blasting her pink neuroblasts forwards from her eyes and tail, with the flower girl raising a crystal hand from the ground to block it and then shot it forwards as she zipped away from it as Big hill flew out of the bindings and shouted out, freezing the blasts as he and his sister combined their attacks to form a neuro freeze ray that froze her in space as the girl shouted out and started shivering where she stood as Matter Girl ran forwards, absorbing the wood from a tree trunk as she ran forwards and gave a strong uppercut to her jaw, sending her sprawling to the throne with a groan of pain, the phone and headphones falling out of her dress pocket as Huntress stepped forwards to investigate with a glance before giving out a gasp as she ran forwards and helped up her friend.

"Rosie?" she asked. "Is that you?"

"Huh?" Rosie asked as Huntress removed the stray hair from her face and looked forwards with a smile.

"It's me! Becky!" she said.

"Becky? Tennyson?" she asked.

"In the flesh. You're an alien?"

"...Yeah," she said with a sigh, bunching her legs up to her chest as she sighed and everyone deactivated their suits, still reeling from the battle.

"We need to talk," Ben said.

"No duh," she said.

Later on, the group, now including Rosie had all gathered by the lake to talk, sitting down on the rock with a sigh.

"So," Becky said. "You're a Plumber's Kid?"

"I wasn't always a Plumber's Kid," Rosie sighed, skipping a rock into the lake. "You see, my species is a single-sex race."

"So all Florians are female," Ben asked.

"Indeed," Rosie said with a sigh as she looked to the water and ran her hand across it.

"So how do you reproduce?" Gwen asked as Rosie looked down and sighed.

"Florians mate with other females and as they mate, they spread out roots from their feet that spreads throughout the current planet's surface, which spawn into what you know as forests and flowers. And from the resulting plants form seeds, which overtime grow into new specimens of my kind... well, maybe not my kind specifically."

"What do you mean?" Kevin asked.

"Technically speaking, I'm the only one of my kind. Not the only Florian, of course, but what I mean is that my birth process was different. Most Florians don't grow up with family because once you grow into your form, you're on your own. Not me, though. I was born the same way most mammalian species are."

"How, Rosie?" Jen asked as Rosie sighed.

"You've met my father, of course. The Petrosapien bounty hunter Tetrax Shard."

"Oh yeah. Tetrax did say he had a daughter with a Florian that he separated from," Ben recalled.

"When he was on a mission to Floria, he met my mother, Su'Flow," Rosie said. "And the feeling was mutual. She was the first and so far only one of her kind to mate with someone outside her species, let alone a male one. And from that, she got pregnant with me. The first Florian hybrid ever."

"So how did you and your mom come to Earth?" Allison asked as Rosie ran a hand through her petaled hair and a tear dripped down her eye as her voice started to break.

"My mom's mating with my father was not looked upon kindly by the Florians and she was exiled for treason by breaking tradition. And of course, because of my nature, I was looked upon as an... abomination," she said through tears. "Neither of us is ever allowed to step foot on Floria again. My dad has been away on... work in space. I've never met him either. So my Mom decided to join up with the Plumbers and trained me to use my powers as a Florian. But when I turned 10, I started noticing strange things about me. Crystals forming from my skin and the ability to project and manipulate Taydenite from the ground and my limbs. I asked my Mom what it was and she told me the whole story that I just finished telling you. We were installed on Earth, given ID masks to protect us from the humans and the rest, as they say, is history."

"Whoa," Ben gasped as Rosie sighed and bowed her head.

"That's one of the saddest stories I've ever heard," Jen said.

"I know, but it's true," she said as Becky walked up to her friend.

"Look, Rosie. I know how you feel."

"No you don't," Rosie sighed. "You don't know what it's like to be hated by your own people."

"We kind of do," Allison said. "We're a superhero team. We get criticisms every day. They can think what they want about you, girl. But what matters is what you think of yourself. You have friends that love you here and nothing's going to change that."

Rosie sighed as she got to her feet and wiped off her flower dress before taking her I.D. mask from her pocket and placed it on, turning back to her faux human form.

"So why did you call us out here with that fight?"

"I was trying to defend the forest because as a Florian, I take comfort with nature, as you can imagine. Sometimes I feel like the plants are the only ones that understand me."

"They're not," Jen said. "You have us."

"When I heard the Omni-Team was back and I saw you fighting the DNAliens, I knew you would be coming, so I wanted to test you guys."

"It worked. We want you to join our team."

"You do?" Rosie asked.

"Of course we do," Gwen said. "You'll be a valuable addition to our fight against the DNAliens. They want to conquer this planet and all living things in it. Including nature."

"This planet is practically my home..." Rosie said. "Okay. I'll do it."

"Great!" Allison said as they one-by-one shook hands with the hybrid and smiled as they departed.

"I gotta get going. Tell what's going on to my mom," she said. "Well... bye."

She then walked off back to the city as the others walked back to Kevin's car to drive off.

"So, you want to tell her that her father helped Vilgax blow up his home planet?" Ben asked with concern.

"It's not worth it. He'll have to tell her that herself if he ever sees her again," Gwen said as Kevin drove off with Allison close behind.

After getting dropped off at home by Kevin, Ben and Jen smiled as they walked into the house to see their parents sitting down in the seats in the living room as they looked on in shock.

"Ben? Jen?" Carl said. "Could we talk to you two for a second?"

The twins gained a nervous look on their face as they looked to each other and gulped as they sighed.

"Are we in trouble, Dad?" Ben asked. "Did we do something wrong?"

"Of course not," Carl said as he turned to his wife with a wink.

"Great news, kids!" Sandra said. "The company is sending me out for a meeting out of the country."

"Out of the country?" Jen asked. "How long are you going to be gone?"

"Oh, it's not how long I'm going to be gone, sweetie," Sandra said. "It's how long we're going to be gone. We're going on vacation!"

"No way!" Ben and Jen said as they stood up excitedly.

"Not only that, I just so happen to have four extra tickets aside from the four of us and Emma," Sandra said, handing two to the kids.

"We don't even need to think about who's getting these," Ben said as he jabbed his sister playfully and she giggled. "So where are we going?"

"None other than the City of Love itself," Carl said, holding his wife close as the twins each gained a shocked look on their face and looked to each other with a dumb grin.

"We're going to Paris?!" Jen asked.

"We're going to Paris," Ben confirmed as the two embraced in a warm hug and spun around with their smiling parents watching nearby. "When do we leave?"

"Next week," Sandra said. "It's gonna be a blast there."
