Tai had no idea what happened when he next opened his eyes.
He now found himself in a strange cave that had hieroglyphics inscribed upon on the walls.
"Wh... where am I? And where are Davis and TK?" Tai asked as he looked around, confused as to how or where he was, while concerned to the situation of his friends.
"Tai!"
Hearing the voice, Tai turned to see someone he thought he never see again, Agumon, who then leapt into his arms and hugged him.
"Agumon!" Tai said as he and Agumon smiled at each other, before asking. "You're here as well?"
"Yeah. Something strange is happening to the Digital World, and before we could check it out, me, Veemon and Patamon were suddenly transported here!" Agumon said in reply.
Hearing that, Tai asked, thinking his arrival was no coincidence. "You as well? And Patamon and Veemon?"
About to question Agumon further, both were interrupted.
"Tai! Agumon!" They heard two voices call out, making both look over to see TK and Davis running towards them, but they were not alone, to which Veemon and Patamon were with them as well.
While glad to see his friends were alright, as well as their Digimon, Tai then asked. "Guys. You are all here too?"
"Yeah, we were suddenly reunited with Patamon and Veemon and then heard your voice." TK told Tai.
"So where are we?" Veemon asked, while looking around, making him comment. "I've never seen a cave like this before."
"I don't know, but I see light ahead." Agumon replied as he pointed ahead, causing the others to look in the direction of Agumon's pointing and too saw the light he spoke of.
Following the light, the Digidestined all ran to the end of the tunnel to find themselves in a massive temple that had stone pillars placed throughout the area, amazing them all.
"What is this place?" Davis then asked.
"It looked like some sort of secret temple." Said Patamon.
Suddenly, Tai and Agumon sensed something, making them turn around and bring up their arms, blocking a punch from Marcus and his Agumon.
"Tai!" Davis called in concern for his friend, while Veemon called out Agumon's name in worry.
"Hey, what's the big idea?" Tai questioned as he kept his arms up, to which he had managed to grasp Marcus' fist firmly in his hand.
"Alright you're going to tell me what's going on here and why did you abduct us!?" Marcus ordered.
"Yeah, you heard the boss! Tell us or we'll beat you down!" Marcus' Agumon snarled, bracing himself against the other Agumon.
"I think you need a timeout!" Tai's Agumon snarled, before he leapt at Marcus' Agumon and slammed a kick into his chest, causing the bigger Agumon to stagger back.
"That does it! Pepper Breath!" Marcus' Agumon yelled, letting his temper get the better of him as he unleashed a fireball from his mouth.
"Pepper Breath!" Agumon called back, firing his own and causing the two fireballs to collide with each other and explode from the contact.
While the Agumon had begun fighting, Marcus had broken free from Tai's grip, to which the two begun to fight again.
However, both stopped when both Tai and Marcus' fists were grabbed by Mikey, who just appeared to stop the fight, while Shoutmon stopped the two Agumons by stepping in between them and held his arms out to stop them.
"Guys, stop it!" Mikey yelled, before saying, trying to calm them all down "I don't know what's going on but we didn't kidnap each other. We are allies."
"Mikey is right. And as Digimon King, I order you both to stop this fighting now." Shoutmon ordered.
"King? When were you our 'King'?" Patamon asked, confused, while part of him thought Shoutmon's headphones were on a little too tight.
"Listen it's not what you think. We are not the ones who brought you here. We were brought here as well." TK told Marcus.
"Is that so?" Marcus said as he stood up, before he questioned. "How do I know if we can trust you?"
"Because we are like you, humans with Digimon as our friends, trying to save the world and all that we care about." A voice explained, as Tagiru appeared with Gumdramon.
And with them were Takato, Guilmon and Takuya.
Seeing the new group, Tai asked. "So you guys were brought here too?"
"Yeah, but I don't know how I was teleported here while outside Guilmon's hideout." Takato said in reply.
While he saw the Digidestined, part of him wanted to say how great it was to meet them and it was them that inspired him to make Guilmon.
But keeping his cool, Takato remained calm, instead of star struck.
Having to ask, Takyua spoke up. "So what is this place and where are we?"
"First things first. We have to know where we are" Said Mikey.
"Takatomon look! Over here in the centre! Guilmon sees something!" Guilmon called out, rushing over and causing the others to follow.
Running to Guilmon's location, the Digidestined, Tamer, former Legendary Warrior, DATS crew and Fusion Fighters all saw something unusual.
Three swords that were in three separate stones.
One was a double-edged arming sword with an orange handle.
"Tai, look. On the base of the rain guard, isn't that?" Tai's Agumon asked as he saw a familiar orange sun symbol on the rain guard.
"The Crest of Courage?" Tai finished, feeling amazed and confused as to why such a blade was marked with the symbol.
"TK, look! That blade has the Crest of Hope on it!" Patamon then called out, to which TK looked over at the left sword and saw it had angel-like wings for cross-guards and a yellow symbol of Hope imprinted on the blade.
"You're right, but what does this mean?" TK asked, getting more questions than answers.
"Hey, red dinosaur. That huge fire like blade has a symbol based on your chest." Marcus' Agumon said to Guilmon.
Looking to the right, Guilmon and Takato saw a huge broadsword crafted to look like fire, while the Digital Hazard symbol was imprinted on the base and near the handle.
"You're right." Takato said, amazed, only to then ask. "But how is that possible?"
"So are these swords supposed to represent something?" Asked Davis, who was just as confused as ever.
Feeling a strong urge, Tai, TK and Takato walked forward to inspect the swords, but stopped when their Digivices began to glow brightly.
"Huh? What's happening now?" Takato questioned, withdrawing his D-Power, while Tai and TK withdrew their Digivices, only to see to their surprise, their Digivices had changed.
All three were now Digivices, which were slightly designed to resemble swords, a screen had appeared in the middle and buttons were near the bottom, while on the top were clips, which could allow them to attach their new Digivices to their belts.
"Our Digivices changed?" TK asked, amazed, as he and the others then stepped down, making Mikey comment. "I've never seen a style like that before."
As the group continued their discussions on the change of their Digivices, none of them saw Agumon, Patamon and Guilmon going up to the swords, almost as if drawn by the blades.
"So if we find other swords like those, would our Fusion Loaders change too?" Tagiru asked as he looked at his.
"Hmm... if it did, something must be happening to the Digital World" Marcus said, deciding to put his question of what a Fusion Loader was for later.
"Wait... you have a Digital World too?" Takuya questioned, before saying. "So do we."
"Then all of our Digital Worlds must be in peril." Davis said, worried to what was happening to their worlds and their friends.
However, he and the others were interrupted when Veemon yelled out. "Agumon, Patamon, kid, don't touch those!"
But it was too late, for Agumon, ignoring Veemon, then grabbed the hilt of the sword with the Crest of Courage, Patamon flew above the sword marked with the Crest of Hope and grabbed it, while Guilmon grabbed the hilt of the huge sword with the Hazard symbol on it.
With the three Digimon, now holding the hilts, three huge lights emitted from the symbols of the swords, which then engulfed Agumon, Patamon and Guilmon, making the three Digimon yell out as their bodies began to glow too.
"Guilmon!" Takato called out, concerned for his Digimon partner.
And as much as he, Tai and TK wanted to do something to help save their Digimon, the lights intensified and filled the room, blinding them all.
Finally, the light soon died down, allowing the group to see once again, before they heard the swords then pulled out of the stones, to which Tai turned to where Agumon was, hoping he was alright, but was just stunned at what he saw.
Agumon stood before the stone slab, but his appearance had changed.
His body had grown, to which he was now taller, around an inch shorter than Tai.
His chest had taken on a more muscular form and now, he had a belly button.
His arms and legs had grown in size and strength, while a red loincloth covered the back and sides of his waist, to which his tail poked out from the hole at the back.
He now held the sword with the Crest of Courage on it in his right hand, while on his left arm was a huge shield, which closely resembled WarGreymon's shield.
"Tai..." Agumon said, his voice now deeper from usual, as he turned to his friends. "I feel... strange."
"I'll say. You've changed, take a look at yourself!" Tai called out in reply.
Agumon looked down at his body and looked shocked as he looked all over, making the Digimon of Courage then question, matching the shocked expression on his face. "What the...!? My body! What happened to me?"
"You're not the only one." A voice told Agumon from his left.
Patamon revealed it was he who spoke, as well as had changed too, for he now stood on his two hind legs, which had turned into legs.
His body changed too, as it had turned to a more anthro-like form, which was just as muscular as Agumon's.
He wore a light coloured tunic around his waist and wielded the sword with the Crest of Hope in his hands.
"Patamon, you too?" TK gasped, surprised greatly ast Patamon's changes.
Confused and stunned, but wanting to know, Gumdramon questioned. "How... how is this all happening?"
"But wait... if they changed... what about...?" Davis began to ask, before the answer came to them soon enough.
Guilmon walked from the right of Agumon, resting the huge blade on his shoulders and showing he too had changed.
Not only was he was now an inch taller than Renamon, but his body had lost its fat, to which his stomach and chest had turned far more muscular than before, giving him abs and a four pack.
Around his neck, adorned a brown scarf, while mentally, he seemed to have lost all his goofiness, looking at Takato and the others in a more mature and serious way.
"Guilmon, your body... what happened to you?" Takato asked in surprise.
Guilmon looked at his hand and he spoke in a normal tone. "I don't know, Takato. But I feel more mature... more adult. What has happened to us, and where did this incredible power come from?"
Sensing his strength, Patamon suddenly commented. "You're right. I feel more stronger too."
Seeing their changed forms, Takuya asked. "What's going on here?"
"Digi Heroes, you have removed the legendary Digi-Swords from their resting places and gained their powers." A voice told them, making everyone all look up to see Azulongmon floating in front of them.
"Azulongmon?" Davis called out, before the leader of the younger Digidestined asked. "What are you doing here?"
"I'm sure you're all aware of what was happening to your Digital Worlds?" Azulongmon questioned.
"Yes, it's all turned blurry and some parts of it is disappearing." Marcus' Agumon said in reply.
"That's because someone is merging all the Digital Worlds into one." Azulongmon told them, which shocked everyone at what they had just heard.
"And because of that, your worlds will become connected and everything will be thrown into turmoil." Azulongmon then said.
"This is not good." Shoutmon stated, worried for his friends, before having to ask. "So was it you who brought us here?"
"Yes. I brought you all here because of a certain legend. You all not just Digidestined, Tamers, Legendary Warriors, DATS or Fusion Fighters anymore. You are now the Digi-Heroes, a group who will bring peace back to those worlds. The Digi-Weapons are your destiny." Azulongmon said.
Guilmon then held his blade up to look at it.
"So this is one of the legendary Digi-Weapons?" He asked.
"Yes it is. There are one for each of you. They are hidden in special temples such as this one. Tai, your Agumon holds the Sword of Courage. TK, what Patamon hold is the blade of Hope. And Takato, Guilmon now wields the Blade of Hazard. All weapons are indeed powerful and they will be even when you Digivolve with the swords and your Digi-Destinys."
"Digi-Destiny? You mean our new Digivices?" TK asked.
"I plead you, Digi-Heroes. Please find the true source of the threat and save all our worlds." Azulongmon just said in reply, before he then vanished.
Tai nodded, accepting his new role, before he turned to the others.
"Well, I guess we have no choice. Guess we're in another adventure. For those who don't know us, my name's Tai Kamiya, the Digidestined of Courage. And that Agumon is my Digimon partner." Tai said, introducing himself and Agumon, before he continued. "This TK Takaishi and Patamon, the bearers of the Crest of Hope. And lastly is Davis Motomiya and Veemon. I chose Davis to act as leader of the new Digidestined because I had faith he would prove to be a good leader, and I was right. And while Veemon wields the power of Courage, just like Agumon, he also has the Crest of Friendship and Miracles as well."
"Making us a force you don't want to trifle with." Veemon stated proudly.
"I know who you guys are. My name is Takato Matsuki." Takato smiled, before he turned to his Digimon partner, who smiled back. "And this is my partner, Guilmon."
"I am Takuya Kanbara. Before all this I could fuse myself with a force called the Spirit of Flame to become a Digimon, but that was a long time ago." Takuya said, before saying in a confident tone. "But I'm sure I can help you guys stop whatever evil is attacking our worlds."
"I am the Street-Fighter, Marcus Damon, and this is my Agumon." Marcus said, introducing himself and his Digimon partner, to which he could agree to get along with the others if it meant fighting strong enemies and saving the Digital World and his friends.
"I'm Mikey Kudo." Said Mikey.
"I am Shoutmon, the Digimon King of my world." Shoutmon said.
"And I am the Superstar Digimon, Gumdramon!" Gumdramon announced proudly,making Tagiru say. "And I am Tagiru Akashi. It's great to see you all again."
While Mikey, Shoutmon and Gumdramon were in agreement with the Superstar, the others were confused, having no memory of ever seeing him before.
But before any could ask Tagiru when they met, a section of the cave's wall opened, to which the heroes all felt a breath of wind hit them.
"That's our way out. Let's go you guys!" Tai said as they all ran out of the cave and back into the fresh air.
Their adventure had begun.
