I do not own Digimon or any of its characters.
Izzys office, 1 day after the visit to the digiworld.
The whole group of digidestined is present in Izzys office. The older generation as well as the younger generation. All of them met to discuss devimons return and Stingmons surprising digivolution to Dinobeemon. Takato is also there, Henry however is missing. He suffered a concussion and a broken arm after he fell down the crack in the ground the day before and is now in the hospital.
"So devimon really returned?" Joe asks.
Izzy nods and says "Yes, and he has gotten a lot more dangerous since the last time we met him. He used black gears to create dark copies of our digimon that even digivolve when we did. Luckily Kabuterimon wasn't affected and we were able to overpower them. While the others split up they were attacked by a mega level digimon and were almost defeated and after we met again, Ken fell down a crack in the earth and was attacked by a Clockmon that sent him back in time, an ability a normal clockmon shouldn't possess. Each time, they spoke about a 'master'. We also noticed that rifts between worlds have been appearing, not just between the real world and the digiworld, but also between other worlds. That's where Takato and Henry come from."
Suddenly DemiV-mon who was sitting on Davis lap the whole time shouts "Now I remember why I recognized Stingmon the first time I saw him! I fought with him against Kimeramon!"
"You didn't really" Ken explains "You just remember that because that was the moment we were sent back to by the Clockmon. But you remembering it is evidence that we changed the timeline a little bit, luckily not in any way that would change too much. But we have to be careful next time we see a Clockmon."
"But we also have good news" he adds "while the Clockmon temporarily sent me and Henry back in time, Stingmon digivolved without D.N.A digivolving. Takato told us that the digimon that caused it, Calumon, has the ability to let any Digimon digivolve. Using that information me and Izzy came up with something."
"Thats right" Izzy continues as he takes 4 little devices out of a drawer in his desk. The devices have the shape of the amulets that the older generations used to store their crests in, before they were destroyed. The space for the crests is empty and it has 4 little arms on the downside.
"I call them, the Calucrests. When Stingmon digivolved to Dinobeemon it used Calumons power to do so, but the digivice couldn't save it. You can attach these things to your digivice to do so. The next time Calumon causes one of your Digimon to digivolve, it will save the energy so you can reuse it to digivolve to Ultimate and potentially even Mega without the use of DNA digivolving, which would increase the number of battle ready digimon in the group."
Izzy hands them to Davis, Ken, Yolei and Cody and they attach them to their Digivices.
"One thing I don't understand" Davis says "why did Stingmon digivolve to Dinobeemon? I thought Paildramon was his and XV-mons Ultimate level?"
"I was asking myself the same thing" Izzy answers "So I did some digging in the digimon analyzer and I realized that Paildramon, Slyphimon and Shakkumon aren't actually fusions between digimon, they are just the normal ultimate forms of XV-mon, Aquillamon and Ankyllomon. Stingmon, Gatomon and Angemon are just used as replacements for the power of the crests"
At that moment Matt raises his hand like a student asking a question. "Could you do the same thing for Wargreymon and Metalgarurumon? Two Omnimons could be really helpful."
"Unfortunately, it won't work that way for Omnimon" Izzy replies "Omnimon is a true fusion between Wargreymon and Metalgarurumon, not a DNA digivolution."
At that moment, everyone can hear an explosion nearby. Everyone rushes outdoors to see a huge rift, about the size of a skyscraper. A digimon just as large steps out of it. It's a humanoid dragon digimon covered in red and white armor. It has the symbol of a sun on the tip of its tail and six folded red armores wings. In front of him is an about 14 year old boy with a red jacket and white shirt. He tries to push him back but he fails due to the enormous size of the digimon he is trying to push.
"Shinegreymon what are you doing what has gotten into you?" he yells.
Izzy quickly types stuff into the digimon analyzer on his laptop to confirm his suspicions. "Shinegreymon, level mega" he reads.
"Okay this is a mega level digimon and it's threatening to destroy the city, you know what this means!" Tai shouts. Everyone nods in agreement and 8 digivices begin to glow.
[Agumon warp digivolve to... Wargreymon]
[Gabumon warp digivolve to... Metalgarurumon]
[Tentomon warp digivolve to... HerkulesKabuterimon]
[Gomamon warp digivolve to... Vikemon]
[Biyomon warp digivolve to... Hououmon]
[Palmon warp digivolve to... Rosemon]
[Patamon warp digivolve to... Seraphimon]
[Gatomon warp digivolve to... Magnadramon]
After the light surrounding the Digimon dissapears, 8 Mega Level Digimon stand ready to battle. The younger generation who had never seen most of the mega forms stare at the digimon in amazement. The younger generation also nod to each other and prepare themselves to do the same thing.
[V-Mon digivolve to... XV-mon]
[Wormmon digivolve to... Stingmon]
[Armadillomon digivolve to... Ankyllomon]
[Hawkmon digivolve to... Aquillamon]
"Alright let's try out these new things Izzy gave us" Davis says as he holds his digivice up into the air, but nothing happens.
"Didn't you listen?" Ken asks "Calumon has to charge them first but we don't know how we can trigger that. We can either try to get it to work, or DNA digivolve and help the others"
Davis looks at all the mega level digimon standing in front of them. "They can handle in the meantime, we can get these things to work."
"I'll help" Takato says "Calumon is a good friend of mine. I think the others can handle the situation."
The 8 mega digimon approach Shinegreymon but don't attack it.
"Hey you!" Sora shouts to the boy in the red jacket "who are you and what are you doing with that digimon?"
"My name is Marcus Damon and this is my partner Shinegreymon" the boy responds "we suddenly found ourselves in a different digiworld from the one we are used to and Shinegreymon was hit in the back by some weird black gear. He started freaking out and went trough a portal and now we are here"
"If he was hit by a black gear we have to get it out of him" Matt yells from the back of Metalgarurumon.
Metalgarurumon attacks with its missiles which freeze parts of Shinegreymons body.
"What are you doing?" Marcus shouts as he punches Metalgarurumon causing it to fly back a few meters.
"We are tring to get the thing causing your partner to go berserk out of it" Tai replies as he comes running behind Matt.
Marcus drops his fist but still has an angry facial expression. "I don't know who you are but do you really think you can beat a mega level digimon?" Marcus asks angrily.
At that moment all the digimon position themselves behind Tai and Matt and Tai says "Of course. We've got 8 of them"
The 8 digimon now disband and position themselves around Shinegreymon and use their special attacks on them causing the black gear to fly out of Shinegreymons back and explode. He stops moving and looks around himself in confusion until he sees Marcus next to some other people he doesn't know. He also notices 8 other digimon around him. Before he can say anything a rift opens and Devimon followed by 3 Vilemon appears in the real world.
"He can enter the real world freely?" TK gasps.
"Oh Shinegreymon" Devimon laughs "you already did so much beautiful destruction, did you really think I would just let you go?"
Devimon does a movement with his hand and a hundreds of black gears fly out of the rift, right into Shinegreymons back. It cries out in pain before his upper armor becomes black and his legs become white. He grows wings and a sword out of black fire and his eyes become a cold stare.
"Deal with that, Digidestined!" Devimon says mockingly before he and the Vilemon acckompaieing him leave trough the rift, closing it.
Shinegreymon let's out a loud and deep cry as he uses his sword to knock Wargreymon from the sky. Vikemon quickly runs to the point of impact and catches his friend.
Meanwhile, Marcus has a look of fear in his eyes. Because of the black gears Shinegreymon reached Ruin Mode again, a corrupted version of the burst mode which made Shinegreymon turn back into an egg.
"What is that?" Sora asks at the sight of Shinegreymons changed color and more aggressive behavior.
"It- It's the burst mode" Marcus stutters "It's a power boost beyond the Mega level. But that's not a normal burst mode, those things that flew into Shinegreymon triggered the Burst mode wrongly. This Form is highly unstable and dangerous. I doubt you'll be able to beat him now."
"It's like the time Greymon digivolved to Skullgreymon." Izzy adds.
The digimon get into combat positions again but Marcus interrupts.
"Didn't I say that this forum is really unstable?" He shouts angrily "If he is defeated or drains all of his power he will trun back into a Digiegg!"
"Okay, stop Shinegreymon from destroying the city but dont hurt him, it might make him more unstable" Izzy commands "I'll try to figure out some other solution in the meantime!"
Shinegreymon uses his sword made out of black fire to slash everything in his sight. The digimon in the air are able to dodge his attacks. When Shinegreymon realizes that he can't hit them, he tries to attack a nearby skyscraper. He swings his sword but Wargreymon interferes by holding the hot blade in his hands.
"Tai, I won't be able to hold his sword for much longer, I need more power"
Tai listens to his partners request and looks at Matt who immediately knows what he wants.
"Metalgarurumon, help Wargreymon, form Omnimon!"
Metalgarurumon runs towards the building with high speed. When he is below Wargreymon he turns into blue light which hits Wargreymon causing him to turn into the grey sword while the rest of Omnimons body forms next to it. Omnimon uses the grey sword to hold back Shinegreymons sword. Meanwhile the other digimon try to hold back Shinegreymons body as good as possible. Vikemon is at the legs where is tries to push them back. Herkuleskabuterimon and Seraphimon try the same but in the air and in Shinegreymons chest region. Rosemon uses her vines to pull Shinegreymon away from the building while Hououmon supports her. Magnadramon wrapped herself around Shinegreymons neck and tries to pull Shinegreymon away from the building as well.
In the skyscraper a few teenagers watch the battle.
"Hey, isn't this the monster that fought that virus on the internet a few years ago?"
Some whisper.
"I think so, but I think he is one of those dangerous digimon the government warned us about"
On the battlefield, Izzy types things on his laptop while trying to figure out a solution to defeat Shinegreymon without killing it.
"I GOT IT!" He jumps up in the air "Tai, get Davis and Ken here! We need Imperialdramon Paladin Mode!"
Tai runs back to the location where the others tried to get the Calucrests to work, hoping that they figured it out by now.
He arrives and sees all the Digimon still on the champion level.
"Davis, Ken! We need Imperialdramon RIGHT NOW!"
"Has the situation gotten that serious?" Takato asks "In that case I'm coming as well"
[Guilmon biomerge to... Gallantmon]
"Huh where did Takato go?" Davis says in surprise.
"I'm right here" Gallantmon replies "me and Guilmon merged to reach the Mega level"
Davis wants to open his mouth but with all the weird things he has already seen and heard about Takato, he decides to keep his mouth shut.
The group arrives at the scene where Shinegreymon managed to land a hit at the building while Tai was gone. Omnimon distracts Shinegreymon by blocking its attacks while the other Digimon try to support the building so the people inside evacuate it.
"Alright" Izzy shouts so everyone can hear him "Davis, Ken, form Imperialdramon and use Omnimons power to change to paladin mode. Then, by using the reset sword, Shinegreymon should turn back into a Rookie."
"Got it" Ken and Davis say as they prepare to DNA digivolve but suddenly Stingmon gets hit by Shinegreymons tail and reverts back to Wormmon.
Shinegreymon prepares to slam its sword into the group but Gallantmon and Omnimon both use their sword and lance to stop Shinegreymon from hitting them. Out of nowhere more rifts with black gears streaming out of them suddenly open and fly into Shinegreymon, making it stronger. It gains the power and breaks trough Omnimons and Gallantmons defense. The group is about to be hit. In an act of desperation, ExVeemon tries to stop the sword with its bare hands and actually manages to do so for a few seconds but it slowly uses its grip. Right in that moment Calumons forehead begins to glow and a light shoots into Davis digivice, filling up the crest, which vanishes into his digivice.
[ExVeemon digivolve to... Paildramon]
Paildramon uses its additional power to push back the sword a little bit but he is still not successful. Davis digivice, which now has Calumons energy saved in it glows again.
[Paildramon digivolve to... Imperialdramon]
Imperialdramon immediately switches to Fighter mode to be able to hold back the sword and he actually pushes it back. Omnimon and Gallantmons now stand behind him and help push him back which makes Shinegreymon fall on its back. Omnimon then turns its energy into a sword which Imperialdramon grabs to become Paladin Mode. Imperialdramon armor changes to a shining white. At Omnimons place, Agumon and Gabumon are left behind. At the sight of Agumon, Marcus is filled with a little happiness but he realizes that the Agumon doesn't have the red wristbands that his partner wears. It's also not as chubby as his Agumon. Imperialdramon Pm uses the chance and rams the reset sword into Shinegreymons belly. Most of his body turns into black gears which explode. The only thing left behind is a pink Koromon. Marcus immediately runs in its direction and kneels next to it.
"Agumon, are you okay?"
"I'm okay Marcus" Koromon whispers.
Authors notes: The calucrests obviously aren't based on any actual Canon, but they are there to solve a problem I encountered while writing. The 02 kids are pretty much useless with the exception of Imperialdramon because the digimon they need to digivolve to Ultimate can reach Mega by themselves so there would be no need To DNA digivolve and they would be stuck on champion. The calucrests are there to solve this problem and make them useful in battles. Another thing, I decided to make this a crossover of digimon in general, Data Squad/Savers was easy to incorporate because it shares the normal Champion/Ultimate/Mega system with Adventure and Tamers. Frontier and Xros Wars are a bit more problematic because Frontier and Xros Wars don't share the same level system, especially Xros Wars. I have to look for a way to incorporate them into the story as well but I don't have any concrete plans on them right now. Anyways thanks for reading and reviews are always welcome.
