"Okay then is everyone all together?" Henry asked as he looked at the group, consisting of Takato, Agumon, Rika, Renamon, Ai, Mako, Impmon, Ryo, Monodramon, Kazu, Gumdramon, Kenta, MarineAngemon, Suzie, Lopmon, Jeri and Calumon.

"We're all together, but there's one problem. How are we to return to the Digital World?" Kazu asked in a cocky-like manner, making Kenta say. "Yeah, Mr. Wong closed the portal to the Digital World and we all cannot return there."

"Not all the portals." Takato spoke up, causing everyone to look at him, making the brunette add. "I saw the portal still open at Guilmon's old hideout and I haven't told everyone of this because I thought something like this may happen."

"Why didn't you tell us this before?" Ryo asked.

"Like I said, I thought it could come useful in the future." Takato replied.

"Well why are we just sitting around? Let's get going to Guilmon's hideout and see if it's still there" Rika said, which made the others nod in agreement with the Digimon Queen.

-Within Guilmon's shed-

Agumon and Renamon were the first ones to get inside and looked at the place, making Agumon comment. "So this is where Guilmon hid from the humans? It's like looking at an old temple from the past."

"Yeah, it does bring back memories." Renamon replied, letting out a small, sad sigh, before turning to Agumon and saying. "Agumon, see if you can find the portal while I wait for everyone else."

As Agumon was about to enter the gate, he turned back and asked, curiously. "Renamon, do you remember anything about your past?"

Renamon looked at Agumon in confusion.

"Huh? Well, I wanted a strong partner so when Rika got her Blue Card and D-Power, I was wished by Rika to be her partner." Renamon replied, still a little confused by the question.

"I meant before you were summoned by Rika." Agumon told her.

"Oh, well..." Renamon said as she crossed her arms under her breasts. "I know I've been raised by a shadow organisation, hoping to be stronger and be cold-hearted. But then... with all the adventures with Rika and the others, I began to open up. I now accept my friends as who they are. What I hate to see is my friends disappearing one by one, I mean... we already lost Guilmon."

Still curious about her, Agumon then asked. "How'd you feel about Guilmon?"

"Well at first he was a bit of a child and an idiot who didn't know any better. But then as we continued our adventure with Rika, Takato and the others, he did become more powerful. He's more powerful than me. I guess maybe he disappeared because I treated him so horribly in the past." Renamon replied, tearing up slightly, before wiping her eyes with her right arm and saying. "But I won't give up. I will find him and I will apologize for what I've done to him."

'It wasn't your fault that Guilmon disappeared, it wasn't that. It's something worse.' Agumon thought.

As he looked through the gate and opened it, he saw the portal, making him call out. "It's still here! I've found it!"

"Agumon! Renamon! Wait up!" Terriermon called, just as he and the others finally caught up.

Curious, Mako asked. "Did you find it?"

"Yes, it's still here. It's open for business." Agumon replied.

Takato looked through and smiled as he saw the multicolored vortex, before saying. "Yes, it's still here. Just as I thought."

"How long have you noticed that was there?" Rika asked, making Takato say, sounding a little embarrassed. "Six years ago. I didn't want to tell anyone in case Yamaki decided to destroy it or something."

"Well let's enter. Last one in's a rotten Digi-Egg!" Kazu called out in reply, as they all ran in and straight for the portal, heading for the Digital World.

-Moments later-

Takato rose up to find himself back in the Digital World where the landscape was a little barren and the sky was clouded by darkness.

"This is terrible." Henry said, as they all saw the depression the Digital World was in, before he asked. "Did the Black Digimon do this?"

"They did." Terriermon replied, before saying. "I don't know how to put it but before we came to you, Azulongmon gave us some terrible news."

"The Digital World was given power from a certain source. The Digi Crystal" Calumon told his friends, making them look at Calumon, before Suzie asked. "The Digi Crystal? What is that?"

"The Digi Crystal is what gives life to the Digital World. Around five years ago, the Black Digimon stole it." Lopmon explained, which made the Tamers gasp in shock, before she continued her tale. "And without the Digi Crystal, the world has lost it balance. There's no telling what the Black Digimon would do."

"And it gets worse. Without the Digi Crystal, most of the Digimon here cannot defend or Digivolve, let alone fight. However, we don't have that problem since we are connected to you guys." Impmon said.

Hearing that, Ai stated. "Our only choice is to find the Black Digimon and get the crystal back."

"There is a problem. Where are they're hiding?" Mako asked.

"We don't know." Impmon replied, before suggesting. "Maybe Azulongmon would know."

"I hope we find him." Ryo said.

Suddenly, there was a mighty rumble and they all looked up to see Unimon above them ready to attack.

"Aerial Attack!" It yelled, before firing a blast from his mouth, which narrowly missed them, but they knew they had to fight back.

"Careful everyone, don't let it get you wear down!" Ryo called out, before he told Monodramon "Quick, Digivolve!"

Monodramon nodded and Digivolved to Cyberdramon, letting out a fearsome roar, while the other Digimon attacked as a team.

"Desolation Claw!"

"Bada Boom!"

"Bunny Blast!"

"Guardian Barrage!"

"Kahuna Waves!"

"Diamond Storm!"

"Pepper Breath!"

However, even with their combined might, all the attacks missed, in which Unimon flew around and dodged each one, before countering with another Aerial Attack, which knocked all the Digimon off their feet.

"He has an advantage in the air! No wonder their attacks aren't working!" Henry called out, concerned for his friends.

"We have to do something!" Jeri said as the Digimon struggled to get back up, only for Unimon to come straight at the Tamers next.

"Grr... I don't know if it would work but here goes." Takato said as he took out a Blue Card and then called out. "Agumon, let's give it a go. Digi-Modify! Digivolution activate!"

Agumon leapt up as he felt his energy refill his body and then increase, before his form glowed orange

"Agumon, digivolve to..."

As he shed his skin, showing his Data, Agumon soon took on a new version of Greymon that had blue patterns on his helmet, red marks on his body and the Digital Hazard symbol on his stomach.

"Greymon!" He then announced, ready to continue fighting, while Takato and the others were left in awe.

"He did it! He actually digivolved?" Henry gasped, watching as Greymon looked up at Unimon.

"Aerial Attack!" Unimon called out, firing another blast from his mouth, which Greymon dodged with ease as he just moved aside from the blast and then yelled out. "Nova Flame!"

With his attack, Greymon fired a shot of fire from his mouth, striking Unimon and making the Digimon scream and retreat.

"You did it, Greymon!" Calumon cheered in joy, while the other Digimon were impressed by the new Greymon before them.

"I've gotta say, that's amazing. He's new here and already he can Digivolve to his Champion form." Kenta said.

"Don't get comfortable. He is only a test." Came a nasty voice from the cliffside, making everyone turn to see...

"The Black Digimon!" Renamon gasped.

Among the ten members were Black versions of Guardromon, Cyberdramon, Calumon, Impmon, Agumon, Leomon, Terriermon, Lopmon, Renamon and Guilmon, in which the Black version of Guilmon wore a crown like helmet around his forehead, wore a black cloak and had a muscular body.

"So they are our enemies!" Takato snarled as he saw the Black versions of both his Digimon before them, making the leader of the Digimon Tamers wonder to himself.

Why did they appear before them now?
