The Return of Kurata

Sirens were going off at the DATS headquarters, and a now 18 year old Keenan and Kristy were running towards the portal room as fast as they could.
As the sirens rang, they soon wound up running alongside Yoshi, Thomas and a man with short brown hair and a gray visor covering his eyes.
"Keenan! Kristy!" Yoshi said as she saw them.
"What's going on? Is someone at the portal room?" Keenan asked.
Thomas nodded in reply, before he added. "But we don't know who it is." 
The brown haired man stated. "We're about to find out. Ready."
"Absolutely, Cyclops." Yoshi nodded.
As they entered the portal room, they were surprised to see the portal to the Digital World had been opened, however they were all shocked to see a familiar face, someone they thought they would never see again.
"You!?" Keenan called out, before saying. "I thought you were trapped in the Digital World, Kurata?"
Kurata grinned eviliy and turned to them.
"Well, well, well. We meet again, my old friends." He said, pushing his glasses up his face while he spoke.
"We were never friends, Kurata." Thomas stated, before Yoshi demanded. "What are you up to now and how did you come back to the Real World?"
"You thought the Digital World could hold someone with my genius forever?" Kurata asked, before stating wickedly as a dark aura encircled his body and his eyes turned red. "I have been freed from my Digital prison!"
"But...but how?" Yoshi questioned.
"One of my magics, Yoshi. My powers have brought him back to this world to assist me in my plans." A dark voice replied.
"Ah, Lord Specter." Kurata said as he turned to Specter, who was leaning against the wall. "Soon, we shall have Marcus and Agumon in our grasp."
"Wait..." Yoshi began to say, before she asked. "You mean...?" 
"A false signal calling for help." Kurata replied as he turned his attention back to his enemies and told them. "We told them that you might be trouble and he's falling right into our trap!"
"So all this was meant to lure Marcus and Agumon here. What do you intend to do with them? Put both worlds at risk." Cyclops demanded.
"That and the rest of the timelines and dimensions too." Specter interrupted, Kurata grinned wickedly.
But before Kurata could say something else, he was punched in the face and sent flying back into the wall.
"Why are you here, Kurata!? Aren't you supposed to be gone?" A familiar voice asked in demand. Yoshi and Rhythm turned to see Marcus with Agumon, Lalamon, Gaomon, Biyomon, Falcomon and a new Digimon coming out, one that had the appearance of a human and who's body rivaled that of Yoshi with short pink hair.
"Marcus!" Yoshi and Kristy said, surprised and happy to see him.
"Long time no see guys. Kristy, Keenan, you've gotten big." Marcus grinned, before turning to Kurata and gaining a serious expression, ready to fight.
"Hey Marcus, who's the girl?" Yoshi asked curiously.
"Oh, that's Rhythm. She's Agumon's girlfriend." Marcus replied.
"You have a girlfriend?" Yoshi asked in a surprised tone.
"Actually she's my mate." Agumon corrected, before he said. "But it's great to see you again."
As the Digimon and DATS team was reunited, Kurata had recovered from Marcus's assault and stood up again.
"Good of you to come home Marcus, Agumon. And you haven't lost your touch, I see." Kurata commented.
"Kurata. How did you return?" Marcus questioned in demand, before he noticed Specter and asked. "And who are you?"
"Humph. I could address myself to the pathetic beings you are." Specter began to say as he grinned, before he told them. "But I have a schedule to keep and an opponent for you all to face."
Right on cue, the roof came off and the DATS team was horrified to see Quartzmon standing above them, his six red eyes gazing at them intensely.
"What is that? A Digimon?" Kristy asked in fear.
"Like nothing we've ever seen before." Cyclops commented.
"Alright then. You want to fight? You get a fight. It's fighting time!" Marcus yelled. "Agumon!"
"Yeah!" Agumon replied, getting ready to battle.
Yoshi and Lalamon stood beside them, as did Rhythm.
Specter grinned eviliy and raised his hand.
"LOOK OUT FOR THE PORTAL BELOW YOU GUYS!" A voice rang from the distance.
It was Jeremy, as he, Angie, Spike and the others arrived, but it was too late.
Marcus and Agumon failed to see the portal below them and with them both saying. "What in the...? WHOA!"
They both fell in and disappeared.
"MARCUS!" Yoshi gasped as she saw Marcus and Agumon disappear through the portal.
"NO, AGUMON!" Rhythm cried out in concern as she tried to get to them but the portal disappeared.
"That's two down, two to go." Specter grinned.
"What did you do to my big brother!?" Kristy yelled, demanding an answer from Specter.
Kurata answered for Specter and told his enemies. "We have future plans for them!"
"Why you! You tricked them!" Angie snarled as they joined the DATS team.
"You lot again?" Specter questioned to Angie and the others, before stating. "It matters not though. You're far too late!"
"Double Backhand!" Gaomon shouted, spinning around and making a whirlwind.
"Seed Blast!" Lalamon called out as she shot seeds from her mouth at Specter.
Cyclops released a red blast of energy at Kurata and Specter.
However Quartzmon blocked all three attacks with his hand, smacking Gaomon and Lalamon away while Cyclops dodged the hand.
"Tch. Pathetic. We were planning to finish you off as well but since you have arrived, it will have to wait for another time." Quartzmon sneered.
"Yes, and without saying, I bid you all goodbye for now." Kurata said as Specter opened another of his dark portals.
"We got what we came for. Let's leave." Specter told his comrades, retreating from the DATS headquarters.
"GIVE MARCUS BACK!" Yoshi shouted as she ran to punch him, however the villains got away into the portal before she could reach them.
"So that was the trap Kurata spoke about." Thomas snarled, angered that he was unable to stop them.
"Excuse me. Are you alright?" Lunamon asked, causing the DATS team to turn in surprise at the newcomers.
"It's okay. We're the good guys." Spike said reassuringly. They knew Spike was telling the truth, before Keenan asked. "Alright. But who are you guys?"
"We're from another world that was threatened by that maniac Specter." Angie said.
"Specter? You mean that dark human who kidnapped Marcus and Agumon?" Kristy asked. Angie nodded.
"But why did they take them?" Rhythm asked, as she was truly worried for the two of them.
"I think this should answer your question." Ballistamon said, opening up his chest compartment and handing them the scroll from within.
The DATS team watched the video scroll, horrified when they saw the corrupted Marcus and ShineGreymon defeat Tai and Davis.
"Marcus? Is that why they took them, to turn them evil?" Yoshi asked, worried and concerned.
"No, Agumon!" Rhythm shouted. "How could he do this?"
"It's not their fault. They're being controlled." Dorulumon replied.
"Controlled? But why?" Keenan asked.
In response, Spike and GAgumon told the DATS team about their mission and how Specter planned to kidnap leaders from other worlds to destroy the Digidestined, and at the same time, wipe out the other heroes in the process.
And if the Digidestined go, the other dimensions and timelines would no longer exist.
"That monster!" Kristy said in anger. "Using my brother to ruin the other worlds."
"He's gone too far." GAgumon said, before stating. "We're here to save you from Specter's evil. But Marcus and Agumon are not the only ones who have been captured."
"They got my friend, Mikey. And my mate, Shoutmon." Lunamon said solemnly. Rhythm knew the pain of losing one's mate.
"And if they get Takuya, Takato and Guilmon too, then who knows what they would do." Spike stated.
"Oh no!" Yoshi said, concerned for Marcus.
"We're going to stop them." Cyclops declared. 
"Will you guys help us?" Spike asked.
"Of course we'll help." Thomas replied, not planning to turn his back on his friends or Kurata's insanity for conquest and destruction.
"Agreed. No one uses our friends and gets away with it." Gaomon said.
"We'll all help!" Keenan and Falcomon said in determined unison as Kristy, Yoshi, Lalamon, Rhythm, Biyomon and Cyclops agreed.
"Hold on, Marcus. We're saving you no matter what." Yoshi said to herself softly as she placed her hand on her chest, above her heart.
"The time traveling hover bike is over there. There are two more stops before we reach our destination. And we need all the help we can get." Spike said.
And the now formed group went back to the bike to head to the Frontier universe next.
