A great crisis had happened in the Digital World.
It happened a month ago where a group of Gazimon spotted an ancient and ominous seal and were foolish enough to open it.
However, as they did, dark energy shot out of it which shocked and scared them, before 20 dark figures came out of the seal, staring down at the Gazimon with glowing red eyes.
"Are you certain it's them?" Seraphimon asked as he, Cherubimon and Ophanimon looked at Azulongmon with worry and doubt, joined by Piximon and Leomon, the two also had worried expression.
"Yes. It's them, the Black Digimon." Azulongmon replied.
"It has been many years since we sealed them away." Ophanimon said. "Unlike the other Digimon, they process great evil."
"And there's 20 of them. And worse, they can generate many minions as much as they like. I fear this may lead to a great war that could destroy the Digital World." Cherubimon added, his tone full of concern.
Stepping forward, Leomon replied. "Then we should summon the heroic Digimon. The Digidestined, Tamers, DATS, Legendary Warriors and Fusion Fighters to help us stop them."
"Just the males." Azulongmon then said, which caused Leomon to ask. "Just the males? Why can't the females fight?"
"The dark Digimon have the power to brainwash female Digimon to do their evil biddings, making them their slaves, to do with as they desire. I know they're great fighters, but they would fall under the spell of the black Digimon with ease. It's best to leave them out just to be safe. The boys should fight alone." Azulongmon replied.
"You're right. It happened before, even my might can be corrupted by their evil." Ophanimon said, before turning her attention to Piximon and instructed. "Alright, Piximon. Call all the male Digimon to come to File Island for a meeting. Then we'll all go to the Black Island where the dark ones reside and stop them once and for all."
"You can count on me!" Piximon replied, nodding and saluting.
Several hours later, Piximon delivered the message to all the heroic Digimon about the Black Digimon and the upcoming war.
And thanks to the intelligence of their human partners, the Digimon from the different worlds found their way to join each other once again.
And thus, Agumon, Gabumon, Patamon, Gomamon, Tentomon, Veemon, Wormmon, Guilmon, Impmon, Marcus' Agumon, Gaomon, Shoutmon, Gumdramon, Ballistamon and Dorulumon decided to go, but there were those who don't want them to leave.
At night, Agumon, Patamon and Veemon were about to leave when Biyomon and Gatomon stopped them.
"You're not serious are you? You're not going to leave us!?" Gatomon asked crossly, only for Veemon to reply. "We have to. These things caused these Sovenreigns to be frightened. And if we don't do something..."
"No!" Gatomon shouted, before saying in a determined tone. "We can fight too!"
"Didn't you hear what Piximon said?" Patamon asked and then added. "They can control your minds with ease. You could be our enemy in a matter of seconds."
"It would be better if you girls did stay here and look after the others." Agumon replied seriously.
Usually Agumon was a cheerful person, but seeing him looking so concerned caused Biyomon worry and ask in concern. "But what if you get hurt? Or deleted?"
"If we can defeat at least some of them, then so be it. At least we'll do our part to save the Digital World... somehow." Veemon replied.
"No, you cannot..." Biyomon began to say, before Agumon embraced her, while Patamon hugged Gatomon in a farewell hug.
"If anything does happen, promise us you'll protect everyone and look after the Digital World" Patamon said as he continued embracing Gatomon close to his chest. " Take care, Gatomon."
"We'll miss you all but we've gotta go now." Agumon interrupted, breaking his hug from Biyomon. "Goodbye, Biyomon."
Leaving the two girls standing speechless while their eyes widened, Veemon, seeing Patamon and Gatomon hug, tried to get over his thoughts of the pair together, but his mind was on a far important matter than a crush on the Digimon of Light.
"Let's go. Gabumon and the others are waiting." Veemon interrupted, in which Agumon and Patamon nodded and then all turned and walked away, leaving Biyomon and Gatomon alone.
As soon as they were gone, Gatomon and Biyomon fell to their knees, and wept quietly, while wishing the best for Agumon, Patamon and Veemon.
-Elsewhere-
"Impmon, you and Guilmon cannot go!" Renamon called after Impmon who they were dating for the time being.
"Hey, lighten up, I am surprised they asked for my help. But then again, these black Digimon sound dangerous and I have to do something." Impmon replied.
"We just gotten together and all of a sudden you're just up and go." Renamon said, before saying. "At least let me come. My mind's not easy enough to control!"
"Sorry toots, but you heard Piximon. No girls allowed! It may sound sexist but we don't want you being their puppets." Impmon replied and then admitted. "Besides, you're beginning to become whiny."
"Whiny? I have you know..." Renamon said, only for Impmon to stop the foxy Digimon as he place his fingers on her lips, silencing her.
"Sorry Renamon. But we have to go." Impmon replied in a serious tone, before adding. "And if we get deleted... heck that would happen. We will come back.
"Later!" Impmon called out as he began to walk away, leaving Renamon to watch on with sadness as she watched her boyfriend go.
However, she noticed someone walk past her.
"You're not gonna go too, Guilmon?" She asked as the Hazard Digimon stopped, turned to her and replied. "Guilmon has to. Guilmon promised Piximon. Guilmon must fight to keep the Digital World safe."
"No! You're too young for that sort of thing!" Renamon pleaded.
Guilmon frowned as he began to hate being the youngest of them all, sometimes wishing to find a way to grow and mature.
But his thoughts turned back to Renamon as he then he calmed down and put his hands on her shoulders, staring deeply into her eyes with a serious look.
"Sorry, Renamon. Guilmon has to go. Guilmon promised to take care of Impmon for you. Bye bye" He then said and then turned and walked after Impmon.
With two of the closest Digimon she had known, Renamon suddenly feel the urge to cry.
Sure, she had been dating Impmon... however... she had stronger feelings for Guilmon for odd reason.
And unable to hold back her emotions, she cried as she lost two of her dearest friends.
-Meanwhile, in the DATS dimension-
"I'm sorry Rhythm but me and Shoutmon have to go." DATS Agumon said as he and Shoutmon, who had arrived via a Digi-Gate to gather the last few Digimon and to make sure his mate, Lunamon, was protected, were ready to leave, leaving their mates behind.
"But we can fight too! We won't be brainwashed!" Rhythm protested, as did Lunamon, determined not to let herself fall victim to evil once again.
"No! We won't let you!" Shoutmon yelled, before calming down and saying. "I'm sorry. But when someone calls, the Digimon King must attend to his duty."
"But we're not gonna let you leave us!" Lunamon cried, before the pleasant warmth of Shoutmon's body embracing herstopped her crying, while DATS Agumon hugged Rhythm.
"Sorry but we have to go." Shoutmon told his mate and beloved, before promising her. "But we promise to come back safe and sound."
"So wait for us, ok?" DATS Agumon said as the two broke the hug and disappeared into the darkness, leaving their lovers weeping tears.
And thus begins the greatest war the Digital World had ever seen.
