AN: I do not own HP or Digimon, I also do not like the D-Reaper from Digimon Tamers, it just didn't feel like an actual enemy but then again, either did King Drasil in Digimon Data Squad.
(Realm of the Sovereign-Digital World)
Henry looked at Azulongmon "Now, who is this true enemy?" Azulongmon looked at them "We don't know, we don't even know its name, none of us have ever had contact with it" "Whatever it calls itself, we know what it wants, to destroy us and the Digital World" Rika's eyes had widened "Where did it come from?" "No one is sure, but it's been here since the formation of this world, long ago it disappeared and hid itself deep beneath the layers of the Digital World" Takato blinked "Beneath the Digital World?".
Azulongmon nodded slightly "Yes, allow me to show you" his eyes started glowing and a blue aura flowed around him as the water near them parted to reveal the earth below and a hole "Imagine this hole is real world, surrounded by the layers that make up the Digital World" several circles appeared around the hole, then one massive circle appeared around them "its physical substructure is six layers deep, that's where you first arrived".
Harry nodded "in the beginning, this is all there was to the Digital World, it was empty, dark inhospitable, the early Digimon, our ancestors lived on the physical layer with the Digi-Gnomes and the true enemy, in those early days, the true enemy destroyed many of our ancestors and Digi-Gnomes, those were dark times indeed" Harry clenched his hand and projected the image that was being shown to him into all of their minds".
They gasped in horror at the attacks "there seemed to be no defence against the true enemy, nothing was able to stop its unending destruction, it spread a dark fog across the Digital World" "And it's come back to wipe us out of existence" "It is our greatest fear" "So why did the true enemy come back now?" "You've getting ahead of yourself, one day the true enemy just disappeared" more smaller circles appeared inside the large layer of the image.
"With that threat gone, Digimon began to Digivolve, new worlds were created, though the physical layer of the Digital World remained, few lived there, instead, we Digimon expanded into new worlds for the most part we lived in peace and harmony, we Sovereign Digimon created our own level, and focused our efforts in protecting the rest of the Digital World but the power we achieved only woke the slumbering true enemy so you see, it is our own fault, unless we can find a solution, we will be the cause of our own destruction".
Zhuqiaomon looked at the humans "it is the Catalyst that has allowed us to Digivolve beyond what we once were" he flew into the air and turned to what remained of his castle "Sonic Zephyr!" his attack blew away the rubble, revealing a pyramid "We had to convince the true enemy that we weren't Digivolving to the point where it would become necessary to destroy us so the Catalyst was hidden, in the form of a Digimon".
Zhuqiaomon looked at Azulongmon "But how? You don't have the power to do that" "Ture but something else does, ah, right on cue" a group of Digi-Gnomes flew over, several of them landed on Harry and Catharine and cooed happily, they both smiled before blinking as the Digi-Gnomes flew up above their heads and created crowns out of pockets of data and placed them on their heads, Azulongmon chuckled.
Takato grinned "Ah, the Digi-Gnomes" several Digi-Gnomes flew over with the transparent Mizuno "No way, it's Mr Mizuno" he smiled at them "I heard there was trouble in the Realm of the Sovereign and I wanted to see it for myself so the Digi-Gnomes were gracious enough to bring me here" one landed on Takato's arm "They helped Azulongmon and Mr Mizuno, not to mention, Me, Harry and Henry, it's like they grant wishes or something".
Azulongmon nodded "Yes, it's a good way of putting it" Kenta blinked at Mizuno "So, who is this guy?" Henry shrugged "he's a friend of my dad's" Rika crossed her arms "He's human?" Takato looked at Mizuno "Mr Mizuno, do you know the name of this true enemy that lives below the Digital World?" Mizuno looked at him "The D-Reaper" "D-Reaper?" "Yeah but what exactly is it?" "When the network was first created, a programme was designed to control the growth of Artificial Intelligence".
"The D-Reaper deleted any A.I programme that had exceeded their original parameters, I would imagine that is why the Sovereign have been fighting so hard to stop its return" Kazu stepped forwards "yeah, no wonder they freaked" Harry took a step forward "Mizuno" Mizuno looked at him "Yes Prince Hadrian?" Harry sighed "How would the D-Reaper affect Catharine, Ryo and me? As Digital beings, are we vulnerable to it as well?".
Mizuno frowned "Possibly, that is a good question Prince Hadrian, I honestly don't know, your human sides might stop it but you will definitely be weakened by it" Harry nodded and Mizuno looked at the group "but they shouldn't have freaked out, D-Reaper was a relatively simple programme written to do only one thing, it shouldn't have the strength to destroy such advanced Digimon as the Sovereign, unless…".
Harry frowned "Unless it absorbed the ability to Digivolve itself from the Digimon that it deleted, like Digimon load data" Mizuno nodded with a concerned frown "It's quite possible that the D-Reaper has Digivolved past the Digimon and is now more powerful than they are" Rika frowned "Terrific, what's the bad news?" Mizuno vanished and Harry frowned "His connection to the Digital World was cut, his mind has returned to his body".
Rika looked around "Do we have a plan or are we just going to stand around here yapping?" Kazu looked at her "Well I don't see you coming up with anything, what's your plan missing Digimon Queen?" "Well, we'll climb on Zhuqiaomon and scope things out" "Oh yea, brilliant idea, let's ask the Digimon Sovereign who wanted to turn us into Digi-Fries to give us a piggyback ride" "Chicken" "I'm not chicken".
Harry chuckled before frowning as Zhuqiaomon started growling and trembling, Takato looked at the Sovereign "What is it Zhuqiaomon?" "The true enemy is nearby" Harry looked over the pit and activated mage sight, he gasped at the chaos energy, he heard Cath gasped and nodded before spelling them all to be able to see it, they all gasped "What the heck?" Harry frowned "That is the true enemy I'd imagine".
Guilmon looked up at the Dragon of the East "Umm, Mr Azulongmon, will you help us, please?" "Of course, the Catalyst must be retrieved at all costs, prepare yourselves children, it is time" a cloud formed around them and Azulongmon picked it up before setting off, Rika opened a slight hole in it and looked out "We're flying" Harry turned and saw Takato speaking quietly with Jeri and he sighed 'Soon Jeri, I'll be able to give you Leomon's egg, just hold on a little longer'.
Azulongmon let them out inside the centre chasm, they looked down and saw the energy everywhere and gasped, they saw a blob of it hit one of the platforms and it was completely erased "I've never seen anything destroy so effortlessly" Harry frowned "I have, an old enemy of mine, he was beyond dangerous" he looked down into the hole "We're gonna need to get down there, I can feel Calumon faintly but I don't know how much time he has".
"I must put an end to this!" Zhuqiaomon flew down into the hole "Curious isn't it? How the Catalyst is both the source of our power and the key to our Destruction" "Why?" "the true enemy is drawn to the power the Catalyst give us, it seeks it out and devours everything in its path" Henry looked at the dragon "So you're saying that wherever Calumon is…" "You can be sure that the enemy will appear, leaving a wake of devastation".
"Poor Calumon, it seems like someone is always chasing him" Harry looked up and saw a Cyberdramon fly over and into the chasm "Hey is Cyberdramon" "And Ryo's with him" Cyberdramon landed and Ryo jumped off of Cyberdramon's shoulder "hey, it's the whole gang, I didn't think you'd be here" Harry walked forwards and everyone looked at him, Ryo grinned "Heya Harry" Harry narrowed his eyes and threw a right hook, Ryo stumbled backwards and placed a hand on his cheek.
"I deserved that" Harry growled "You're damn fucking right you did, you stupid, fucking asshole, who said you could go and die on us, you knew you couldn't win that fight alone and yet you took it anyways, I should kick your ass from here to the fucking human world" Ryo winced "I'm sorry Harry, you're right and I should have stayed with Catharine and the others till we found you" Harry crossed his arms and nodded.
"Umm Harry?" Harry turned and saw a lot of shocked faces and groaned "Shit, I wasn't supposed to say that was I?" Ryo laughed "Well, you blew us out of the water didn't you?" Harry glared at him "Shut up Neville, you are still in the doghouse" Ryo winced "But Harry!" he glared at him "Don't you but Harry me Brother, I will kick your sorry ass, I have made it to Mega Level, don't tempt me" Ryo went silent.
Harry looked at the others "When we return to the human world, I'll explain everything, I promise on my magic and my life" magic flared and Ryo nodded "That is a vow, if he breaks it, it will kill him" they all blinked in shock, Rika looked at Harry "Ryo is your brother?" Harry nodded and Rika sighed "we need to talk later" Harry nodded again before gasping as Zhuqiaomon flew up with injuries all over him "Cath, heal him".
Catharine nodded "Digi-Modify: Healing Wave!" Floramon aimed her hands at Zhuqiaomon and the wounds healed, he nodded "Thank you, Princess Catharine" she smiled "Not a problem, Zhuqiaomon" "I couldn't even get close, the chaos overwhelmed me" "I warned you not to underestimate the true enemy, it does eat, it doesn't sleep or feel pain, it exists only to destroy" "So how can we defeat it?".
Azulongmon looked down "The chaos is increasing, hold on tight" Azulongmon pushed the floating rock that they were on into the wall so that it was now a ledge, Harry looked over everyone and saw no injuries, Rika looked at Renamon as the others started discussing options "Renamon" Renamon nodded and they started down the small path in the chasm wall "Umm, Rika, what are you doing?" they all turned to see Rika climbing down, Harry looked at Catharine who nodded before vanishing.
Harry looked at Ryo "Go after them, I'll cut down as much of the chaos as I can along the way" Ryo nodded and went after Rika, Harry let the wings grow from his back and flew into the air before blasting at the chaos with his attacks, Rika looked at Renamon as they were climbing down "If we fall, how long until we hit the bottom?" "It is probably best if we don't think about that" "Umm, Renamon, can we change our destiny?".
"Yes, of course" "Well then, do you think we can somehow change Leomon's Destiny" A voice came from behind them "it has already been changed" they turned to see Catharine smiling at them "Harry is working on it as we speak, within a week or two, we might have Leomon back but we can't have Jeri know just yet because if it fails…" Rika gulped "it would crush her completely" Catharine nodded "Let's go, Calumon isn't going to recuse himself".
They continued climbing down the chasm as they spoke of Jeri, Rika looked at Catharine "You never said why you were here" she smiled "I knew that if I didn't come, Harry would have gone full Lucemon or Dominimon and come after you recklessly, he'll do anything for his friends and those he cares about and you were his first friend in this world so that puts you at the top of the list of people that he would move heaven and earth for".
Rika's eyes widened and she blushed slightly and Renamon smiled, Catharine smiled "There is nothing to be embarrassed about Rika, we're almost teenagers now, well you lot are, Ryo, Harry and I are a bit older as we came to this world from another and were de-aged along the way" Rika blinked "How old are you three?" Catharine smiled "Ryo and Harry are almost 19 now and I'm almost 18, actually, if we were going by our original birth dates in the world and then transferred that over to this world".
She rubbed her chin "Harry was born on the 31st of July 1980 in our old world" Rika's eyes widened "he'd be 32?" Catharine nodded "But in this world he was born in 2000, Ryo was born in 2000 and I was born in 2001, it is why we are more mature than most others" Rika nodded "I see…" Catharine smiled "You like Harry don't you?" Rika looked at her with wide eyes and pink cheeks "W-What? No" Catharine laughed "You do, that is fine, just don't hurt him, he's had enough of that".
They looked down as they heard a familiar voice "Chuga-chuga-chuga" Catharine smiled; they saw a familiar little white Digimon climbing up the wall "Calumon!" "Rika, Catharine" he started running up the slope before jumping into Rika's arms, Rika hugged him, Catharine's eyes widened and she pulled Rika against the wall as a blob of chaos energy flew up just where Rika was standing "Let's get out of here".
Cyberdramon started shooting through the blobs as Ryo pulled Rika and Catharine into a small cave "What is wrong with you? Do you have no self-preservation at all? Do you know what would have happened if you hadn't come back? Harry would have gone on a rampage!" Rika looked down and Ryo walked out of the cave "Digi-Modify: Avenging Knight activate!" two large lances appeared in Cyberdramon's hands.
He flew down and slammed them into either side of the smallest bit of the chasm bottom, he then flew up a bit before spamming the Desolation Claw! Attack at the walls, soon, tons and tons of rocks were covering that hole and everything about it for about 15 feet, only tiny bits of chaos were getting through "Let's go" they started rapidly climbing as red lines of energy started forming under the rocks.
They looked up to see the rest of them and Harry Lucemon mode coming down "We don't have a lot of time, hurry" Rika nodded before looking down at the pit "Rika, would you say something? You're making me nervous" "I'm not going Ryo" "What are you saying?" "We're just kidding ourselves, there's no way we'll escape before it catches us" "What do we do?" she handed him Calumon "I want you to take Calumon" she started going back down.
"What are you going to do?" "Stop the chaos" "Don't be crazy, you'll kill yourself" Rika continued climbing back down with Renamon following her, they skidded down before landing on a small platform "Rika go back" "No" "Please" "No way" "Just listen for once, please, I'm begging you" Rika looked down at the chaos "Go back now and there's a chance you'll survive, stay and you'll be walking into certain death".
"You're staying" "I'm a Digimon, fighting is my way of life, not yours, what kind of partner would I be if I let any harm come to you? Rika? Why won't you answer me?" she looked at her Digimon "We can choose our own destiny right?" Renamon nodded "yes" "Then I choose" the rocks crumbled "To stay and fight with you, I won't let this hurt my friends" 'Harry' they jumped together and a familiar glow lit up the chasm, Harry and Catharine grinned as Ryo scanned the energy and blinked in surprise at what he found.
