Several years had passed since the five teams of Digimon heroes and heroines had been summoned as one in order to take down the twisted Digimon that was Quartzmon.

Working as a team, the Digidestined, Tamers, Legendary Warriors, DATS and the Digimon Hunters had not only taken down Quartzmon's mass produced Myotismon army, but sharing their strength, they had allowed Tagiru and Arresterdramon to destroy Quartzmon with the weapon their combined strength created, the Brave Snatcher.

With Quartzmon's defeat, his Data reset and his form purified into a Digi-Egg that Tagiru stored safely in his Fusion Loader, the teams were taken away from the reality of the Digimon Hunters, where each and every hero and heroine had their memories erased of the events, as per to avoid any time paradoxes or possible calamities of encountering past and alternate Digimon teams and were sent back to their realities, having no recollection of their battle against Quartzmon.

The only ones who remembered the fight against the devious Digimon were the Digimon Hunters, the Old Clock Shop man and those who acted as guides for the Digidestined, Tamers, Legendary Warriors and the members of DATS.

From seeing the other heroes and heroines fight, their determination and skills inspiring him to reveal the truth, Shoutmon had spent ages with the representatives of each Digital World, trying to convince them that merging the five Digital Worlds and allowing all to remember what had occurred to be the best for everyone.

And while some were reluctant at the start, watching the various Digimon teams growing up and mature, it soon became unanimous, to which the representatives used their power to bring the five Digital Worlds into one new Digital World, while restoring the memories of each Digidestined, Tamer, Legendary Warrior, DATS member and every last Digimon that fought with them, allowing the five separate teams to reunite and form one great team.

However, the merger of the Digital Worlds did not come without issues, as many dark and troublesome Digimon decided to take advantage of the change, causing havoc wherever they could.

But instead of coming up against one group of Digi-heroes, however, these troublemakers soon discovered the hard way that they were outnumbered and had to deal with five combined forces, each giving a unique power to the team, Warp Digivolution, BioMerging, Fusion Evolution, DNA Charges and DigiFusion, all these powers made the team a near unstoppable force.

And outside of their duties in keeping the new Digital World protected, though some started off shaky, the teams soon became great friends, leading to the various heroes and heroines crossing from their worlds to hang out with their alternate era allies.

Currently, deep in one of the large forest regions of the Digital World, a group of Dracmon, who had been having fun terrorizing a small village of Koromon, were now running for their lives, looking back to see the rather angry face of a certain white feline Digimon, as well as her human partner, chasing after them.

The Dracomon recognized the feline as Gatomon, the Digimon of Light, while also fearing her partner, Kari Kamiya, the Digidestined of Light and younger sibling of Tai Kamiya.

Much had changed for Kari over the years.

At eighteen, she was now in her senior year of school, her grades near the top of her class, while outside of the classroom walls she had taken to being the captain of the cheerleader squad.

Her physical appearance had changed as well over the years.

While she kept her hair short and framed with a pink clip, her hazel eyes remained filled with kindness and determination, which made the more dark side of Digimon fear her and the innocent love and cherish her, namely from her kind and caring ways.

Her body had developed nicely, not only staying in great shape due to all the conditions she was put through from her duties as a Digidestined, but also from her cheerleading, finding it was more complex than first anticipated, giving her a slender and amazing figure that caught the eyes of most of the boys in her classes.

And with the years passing, Kari had changed her clothing, but kept it similar to what she used to wear, to which the brunette now took to wearing a white jacket that had black patches around the shoulders and along the elbows, running down to her wrists, while a pink top covered her chest and highlighted her D-cup breasts.

Not afraid to show off her sexaulity, Kari also wore a pair of yellow shorts, having designed them to allow easy access to her D-3 and D-terminal, while thigh high stockings covered her feet and a pair of pink and white laced shoes covered her feet.

Yet despite her fit figure, Kari was having a hard time keeping up with Gatomon, who was more then determined to teach the pesky Dracomon a lesson they would never forget.

"Gatomon... slow down I..." Kari started to yell, before her foot landed on what she thought at first was solid ground, only for it to give way, causing Kari to let out a sudden cry as she fell down a dark hole, sliding down what appeared to be a small ramp and soon leaving her in a barely lit room.

"Ok, that hurt..." Kari groaned a little as she slowly got up, looking around to find the strange symbols of the Digital Language written on the walls, knowing if she had Gatomon with her or Izzy's computer, she could translate.

So distracted by what she saw on the walls, the brunette failed to notice the lightly glowing purple orb behind her, moving around slightly as if it had a mind of its own.

'At last, one of a pure heart that I can fill with my power...' The orb said quietly, before quickly shooting towards the brunette, entering the back of her body and disappearing as it sunk into her back, causing Kari to feel like there was a sudden chilling breeze of wind, where she quickly looked around, but found nothing there.

Continuing to look around from the direction of the winds, Kari stopped as she heard Gatomon's voice.

"Kari, are you alright? Can you hear me?" The Digimon of Light called out from above the hole, having stopped her chase once she heard her partner's cry.

"Yeah, I must have slipped. Just stay there, I'm coming back up." Kari replied, feeling that, for some reason, it was not worth mentioning what she found down there, and quickly made her way up the ramp and out of the hole, pulling herself back up to the surface, where Gatomon saw her partner and assisted in helping Kari back onto solid ground.

"I hate to say but the Dracomon got away. But I told them I had my eye on them, so I think they'll know not to bother the Koromon Village again." Gatomon informed, which made Kari nod.

"Let's hope so." Kari replied with a smile, before she heard a familiar voice yell from behind her. "Kari!"

Kari looked to see the rest of her team for the day arrive behind her, which consisted of Takuya Kanbara, Yuu Amano, Damemon, Veemon and the one calling her name, Davis Motomiya.

'Davis...' Kari thought to herself fondly as she watched the maroon haired boy approach her, where he knelt by her side and asked if she was alright, even offering to check her for any injuries as he looked at her with his continued caring eyes.

Like Kari, Davis had changed over the years as well, and Kari found herself quickly falling for what she saw, having long ago developed a huge crush on him.

While his hair remained much the same, as well as his Digital World attire, Davis had matured in ways no one ever expected, not only becoming one of the top students in class and also captain of the soccer team, he had matured mentally, trying to reason before fighting, even with Yolei.

His caring attitude, as well as his looks, also earned the Digidestined of Miracles quite the fanbase, with most of the members of the cheerleaders making small comments to each other, as well as their female Digimon talking about how cute Davis' partner was.

But for Kari, it was more than his looks that mattered, it was the kindness, bravery and care he showed that made her fall for him, but it also made her depressed as well.

It had been a few years since Davis had asked her out, or tried a foolish gesture to try and impress her, and Kari mentally cursed herself for not accepting his offers for a date when she had the chance, believing that he had moved on from her, and that soon, some other lucky girl would be able to say with pride that she was Davis Motomiya's girlfriend.

'Not like you had a chance anyways, it's your fault for letting him slip past you...' A voice in the back of Kari's mind then said, but the brunette ignored it as she looked up at Davis and smiled.

"I'm fine, Davis, I just slipped, but I'm alright. Sorry we let the Dracomon get away." Kari replied, happy to see Davis' caring side as he helped her up, but still upset that her clumsiness allowed the bad guys to get away.

"It's no problem, I sure they got the message and won't be coming back here anytime soon." Takuya assured, getting nods of agreement from Yuu, Damemon, Gatomon and Veemon.

"Yep, so lets get home, I'm starving." Veemon said with a smile, just as his stomach began to growl, causing most of the humans and Digimon present to giggle, while Davis let out a groan.

"You're always hungry, Veemon." Davis pointed out, before he then added as he looked at everyone, taking the lead as he said. "Alright, let's head back to DATS and give our report."

"Right!" Everyone replied back as they made their way back towards the village, unaware of the change of fate that had occured, the room beneath their feet a distant memory to the Digidestined of Light.

-Sometime later-

After finding a Digi-Port and returning to the Real World, the group were now in a large, presentation styled room at DATS HQ, where Davis and Takuya were talking with Marcus, Tai, Gennai, and Commander Sampson, giving their report on the Dracomon, while everyone else was chatting amongst themselves.

But Kari was sitting by herself in the back of the room, her fingers on her temples and her eyes closed as she felt a headache start to form.

"Kari, is everything alright?" The brunette heard Yoshi ask, opening her eyes to see the auburn haired woman and Lalamon looking at her with some concern, where Yoshi then offered. "If you aren't feeling too good, we could find you somewhere to lie down."

"I'm alright, Yoshi, but thanks for the offer." Kari replied, but felt her headache get slightly worse as she groaned a bit.

"Are you sure? Maybe you should...?" Lalamon started to say.

"I said I'm fine!" Kari snapped, surprising not only Yoshi and her partner, but herself as well, looking around to see everyone turn their heads at her outburst.

"Sorry... I guess I should go home, lie down, it's been a long day." Kari apologized as she stood up and made her way towards the room where the Digi-Ports were, Gatomon right behind her as the feline Digimon looked at her partner with concern.

But once she was a few feet out of the room, Kari felt a hand on her shoulder, causing her to turn and see Davis looking at her with concern.

"Are you sure you're alright, Kari?" Davis asked, his concern causing Kari relax as she sighed.

"Yeah, I'm just tired. But thanks for caring." Kari replied with a smile, seeing Davis smile back, before she turned and continued down her way, to which Davis let out a sigh as he watched Kari walk away, wishing he could do more for her.

Despite the years, his feelings for the brunette never changed, and in fact, they had grown, but Davis was sure Kari only saw him as a friend, and he did not want to risk ruining what friendship he had with her by saying something he shouldn't.

Stopping just outside the Digi-Port room, Kari turned and took one last look at Davis, only to see that Rika, Nene and Yoshi had come out and were chatting with him, most likely to see how she was doing.

But despite the logical reason for them talking to Davis, Kari could not help but feel the jealousy build up inside of her.

"Kari?" Gatomon asked concern as she thought she saw something in the brunette's eyes, something she had never seen before, it was like a dark hatred that actually feared the Digimon of Light, never knowing Kari to keep such emotions hidden within her.

"Lets go, Gatomon." Kari merely replied in a distant tone, going into the room as Gatomon followed, both heading back home to get some needed rest.

-Later that evening-

Having collapsed on her bed, still dressed in her outfit, feeling too exhausted to change, Kari sighed as she let sleep take her, while Gatomon watched for a few minutes to see if the brunette was alright, before curling into a ball and falling asleep at the end of Kari's bed.

Had Gatomon only known what was going on in Kari's head, she would have done everything she could to help her, too deep in sleep now to notice the dark aura surrounding Kari's body.

-Inside Kari's mind-

Opening her eyes, Kari felt confusion to see she was in a void of darkness and no matter which way she looked, it was all the same, even turning her head up, it was if she was standing in place and the world was moving to adjust to her body.

"Where am I?" Kari asked aloud, though part of her knew she might not get an answer.

"Where do you think, little Miss Sunshine?" Kari heard a voice say behind her, causing her to turn around and see a figure behind her, one that surprised her by who, or what it was.

The being in front of her looked just like her.

Everything about this individual was the same as Kari, her clothing, her hair, her face, her eyes, but there was something about the second Kari, something that made Kari feel worries, the dark look in her eyes, as well as the wicked smirk on her face.

"Who are you?" Kari asked, stepping back as she tried to figure out what was going on.

"Silly thing, I'm you. Or to be precise..." The figure said as she got closer to Kari and added. "I'm what you really feel, the darkness you keep bottled up inside of you, the voice in the back of your head you try so desperately to ignore, but never really can. I am you."

"What!?" Kari let out in confusion and shock, especially when her back hit what felt like a wall, even though there was nothing behind her, to which Kari could only watch on as this figure, this Dark Kari, continued to approach her with a dark smile.

"For too long I've been trapped inside of you, watching you waste your potential, your true power, on such pathetic ideals like peace, love, friendship... Such concepts make my stomach churn." Dark Kari said with a disgust look.

"Letting everyone still think you have a thing with TK, while letting a prize like Davis slip from your grasp, continuing to act like your so called 'friends' idea of peace is helping the Digital World. You want order, you need a strong, iron hand to do it, and you've had the power all this time to do it, but you're too afraid to use it!" The Kari doppelganger said, her words stinging Kari's heart.

"I'm... I'm not afraid, you don't know any..." Kari started to yell, before she felt a few sets of hands on her arms and legs, looking down to see four sets of dark hands coming out of the shadows, holding her in place.

"I know you better than you know yourself. I know you could have power, you could stop being dependant on others to protect you, but most important, I know you could have Davis. So embrace me, let me take charge, and we can have everything you desire, and all the power in the world to do with as we see fit." Dark Kari said in reply as she closed the gap between her light self, placing her hand on the brunette's cheek as it glowed with a dark aura, causing Kari to stop struggling as her eyes started to glaze over.

At seeing Kari falling under her spell, Dark Kari smiled.

"That's it, embrace my power and I can give you the world." Dark Kari offered, grinning deviously as she added, knowing just how to pull Kari's strings. "And in this new world, you can have him with you, you can have Davis at your feet, worshipping you as the Queen you are meant to be."

"Yes... I'll... I'll embrace you..." Kari replied in a distant tone, giving in and making her dark half smile wickedly.

"Good girl, now the fun can finally begin." Dark Kari said with a smile as she moved closer to Kari, a dark sphere surrounding the two in the process, before everything faded black.

-Waking World-

Back in the real world, Kari's eyes opened, only as the brunette regained consciousness, a dark smile came across her face, while a dark red tint appeared in her eyes.

"That feels so much better." Kari said a loud as she sat up, stretching a bit, while now feeling the dark power running through her body, feeling as though she could take down and crush the entire Digital World.

But breaking from the wonderful feeling of her awakened power, Kari then looked down at the sleeping form of Gatomon and smirked.

"Gatomon, you have always been so loyal to me, so you better believe I have great plans for you." Kari then said as she brought her right hand over to Gatomon's sleeping form, setting it on the feline Digimon's head, where her hand began to glow with a dark aura, her new power corrupting and reshaping the feline to her desire.

-Gatomon's mind-

As Gatomon slept, dreaming she was in the Digital World, happily walking by a steam and seeing the fishes jump out, as though begging her to grab them, the Digimon of Light was caught in a state of shock as one of the fish shot at her, opening its mouth where a line of chains emerged and wrapped around her right arm, just before a second fish copied the actions behind her, restraining the movement of her left.

Confused by the actions, Gatomon was brought into a state of disarray as the world around her began to crack and shatter, the fragments of the world of light breaking away and leaving the feline Digimon pinned to a stone wall of an all too familiar dungeon.

"No, no, no, no, no! Why, why am I here again!?" Gatomon yelled frantically as she struggled against the chains, wanting to wake up and get out of this nightmare before it could start.

"You're here because a part of you never really left here, did it?" A cold, but familiar voice pointed out from the shadows in front of Gatomon, where the Digimon of Light turned to look as copy of herself emerged, only this Gatomon had a dark smirk on her face and a wicked glint in her eyes.

"What are you talking about?" Gatomon questioned, ignoring that she was conversing with a copy of herself. "I hated working for Myotismon, I hated everything he did to me, why would I ever want to come back here?"

"Because you felt powerful here as well." The Dark Gatomon replied, shocking her counterpart as she continued. "You were the one who tortured so many Digimon here, and deep down, you loved the power, you loved the control. I should know, I am you, after all."

Refusing to believe her words, Gatomon shook her head.

"Lies! I was never even supposed to wind up with Myotismon, I was destined to be with Kari and do good for the Digital World." Gatomon said back with a continued defiance.

"While I can agree you're destined to be with Kari, I doubt that silly notion of 'good' is what either of you are meant to do for the Digital World. No matter what you do, darkness always finds a way back." The Dark Gatomon replied with a smirk, her paw moving close as she gripped Gatomon's Tail Ring, slid it off and chuckled.

"You could be so much more if you gave into the darkness, just face the facts, without this trinket, you are no more stronger than a Rookie. You are practically helpless without others to give you strength, but all those who fought for darkness, they had their own power, they had others to command. And with Kari, you both can rule the Digital World as it was meant to be ruled, just embrace me, embrace Kari, and you'll be at the side of a power you could never have dreamed of." The Dark Gatomon finished as her paw glowed with a dark aura, which seemed to seep into the Tail Ring, before she placed it back on Gatomon's tail, smirking as she watched her counterpart's eyes start to glaze over.

"No... I... I have to fight... for my friends... for Kari... for Veemon..." Gatomon said, trying to resist, but found her mind clouding as the effects of the darkness in her Tail Ring continued to consume her.

"Don't worry about Veemon, I'm sure Kari will come up with something for him. As for the others..." The Dark Gatomon started to say as a dark smile spread across her face, where she added. "We'll see what becomes of them."

The dark copy of the feline Digimon then closed the gap between them, causing both to be consumed in the shadows as everything faded away.

What seemed like a couple of minutes to Gatomon was mere seconds in the Real World, where Kari smiled darkly as she watched the change in her partner, where Gatomon's fur changed from white to black, and her paw gloves turned purple.

Removing her hand from Gatomon's head, Kari watched as her eyes opened, showing that they had changed from their usual blue to a bright yellow, before the feline Digimon gave a wicked smirk, stretching her body as she stood up.

"That feels so much better." The new Gatomon said with a purr, before looking up at her partner, no, Queen, where the dark furred feline grinned as she bowed. "Thank you for awakening me, my Queen, I am at your service."

"I'm glad to hear it, my loyal servant." Kari replied with a smirk, before she added in a commanding tone. "Now, get ready, we have a lot of work ahead of us, and I know just where to start."

Seeing Gatomon nod at her, Kari stood up, stopping for a second as she looked down at her attire, looking over at the full body mirror, checking herself out.

"Too much white and pink. I'll have to do something about that later. For now..." Kari started to say with a smirk as she held her hand out towards the mirror as the dark aura surrounded it once more, before the mirror seemed to gain a mist-like fill, before opening and revealing the sight of a dark beach both she and Gatomon where all too familiar with.

"Shall we, my Queen?" Gatomon asked as she jumped onto her partner's shoulder with a smirk, one Kari shared as she nodded, grabbing her D-3 and entering the mirror, which returned to normal behind her, leaving no trace as to where the former Digidestined and Digimon of Light went.

-A moment later-

The last time she had visited the Dark Ocean, Kari felt only fear and despair, only now as she looked upon the dark waters as she stood on the beach, Gatomon still resting on her shoulder, Kari felt powerful and eager for what was about to happen.

"How long do you think it will take for them to notice we're here?" Gatomon asked in a lazy tone.

"Not long at all." Kari replied as she looked around, seeing the yellow eyes and black figures of the Dark Ocean creatures slowly surrounding them, coming out of the water, the mist, even the area behind the pair as they surrounded them.

A moment later, there was a large, slashing sound, causing Kari to smirk as she looked up, seeing the form of Dragomon emerge from the water, before the dark Digimon looked down at her with curiosity.

"You have returned..." Dragomon said, feeling a powerful force coming from the young girl, where the dark Digimon then asked. "Have you decided to join us? To become my Queen and rule in darkness?"

"I have decided to rule, to be Queen, but..." Kari started to say as the smirk on her face turned more wicked, alarming Dragomon slightly, especially when he saw a large amount of dark energy in her right hand.

"I will not be your Queen." Kari finished as she brought up her hand and released a blast of dark energy right at Dragomon, taking him completely off guard as the blast hit him, causing the dark Digimon to scream in pain as he was disintegrated.

All around, the Dark Ocean creatures watched in shake and awe, watching on as the dispersed Data of Dragomon then swirled around Kari and entered her, where the corrupt Digidestined closed her eyes for a moment as the energy entered her, before reopening them, where they glowed a bright purple for a moment, then returned to normal as a dark aura now surrounded her and Gatomon.

Looking around, Kari smirked as she felt the fear growing in the creatures, before she asked in a sly tone. "So, do any of you have any objections to me being your new Queen?"

The creatures all looked at each other, as though talking in silence, before in unison, they all bowed as they began to chant. "All hail the Dark Queen!"

Seeing the creatures bow before them and praise her corrupt partner, Gatomon felt a smirk grow on her face as she said. "Now this is fun."

"And we're just getting started." Kari replied, letting off a dark laugh as the first of her new army pledged themselves to her, to the new ruler of the Dark Ocean, to their Dark Queen.
