Donatello woke up excitedly or at least as excited as he could be. It's his 10th birthday today so that means his entire family is gonna get together to throw him into a cave full of dragon types for the next 6 months. Context is needed huh, well in the Draco family it’s been a tradition since ancient times to send a child into the dragon's den once they reach ten years old. This is so they could learn and grow with the powerful Pokemon for 6 years until they are old enough to train pokemon, or in modern times go on a Pokémon journey. If a child manages to survive for 6 years and come out with a partner dragon they are permitted to leave on their journey. This had been lowered in more recent times because, shocker, most 10 year olds couldn’t survive six years with powerful dragons.
Thanks to his family’s affinity towards dragon type pokemon that’s been with them for centuries as well as his family’s ability to keep at the top of Kanto/Johto’s league for as long as it’s existed, he’s filthy rich. They weren’t the only dragon masters, I mean Lance and Clair are right there, but they were the most abundant and dominant. Anyway back to Donatello maids and butlers are currently rushing around the whole estate decorating, cleaning, etc much to his annoyance. This meant his siblings would pester him about “not getting nervous about his big day." He didn’t care much for what they had to say currently right now he was simply going through his morning routine getting dressed, brushing his teeth, the usual stuff.
He wanted to see the cave he would delve into later today. As he made his way there he got distracted by his father and the concerned look on his face as he typed in the code to open the vault door. It took annoyingly long for the vault door to slowly swing open. His father waited patiently fiddling with an ultra ball. One of the maids ran up to him, but Donatello was too far away to hear whatever she said. His father quickly dismissed her, shooing her away.
In his ten years of life not once had Donatello seen his father open the vault. It was full of valuable items, that’s all he’d ever heard about it. Once his father had fully opened it, it was stunning so much gold, so many rare pokeballs, paintings, there were at least three master balls in the room. His father walked up to a pedestal and grabbed a purely black pokeball and a gray pokeball. Then he walked out with the most concerned look Donatello had ever seen him wear, his prideful powerful dragon of a father looked scared and that scared him
Finally, his father had noticed him “Donny, perfect timing come, quickly, outside.” Donatello had to run to keep up with his father’s speed walk but they made it outside and his father tossed up the two pokeballs. “Donny hold this and don’t get scared just point it in between them.” As he finished his sentence the pokeballs burst open releasing the legendary Pokemon Zekrom and next to it the legendary Pokemon Kyurem. Donatello shivered and immediately began to sweat. He was terrified but he did as his father instructed and held what he now put together were DNA splicers. He clicked the button and twin beams shot at both legends before they roared and began to fuse.
They grew bigger, even more huge than they already were. Ice took over half of Zekrom’s body, its lower body then an arm and after that a wing and its lower jaw and a crest formed on its head with a large yellow scale. Then the beast woke up, tube thingies connected its main body to its tail. They roared blue electricity surging through the tubes from its tail.
Donatello had always assumed he was a prideful kid, fearless and strong like a dragon he still had, but once he took one look at the legendary Black Kyurem…
It took everything Donatello had to not piss his pants right then and there. His father spoke up first “Kyurem and Zekrom I humbly request you once again lend your aid in laying it to rest. For some reason it still hasn’t returned to its temple in the Galar region and it has awoken again in the depths of the dragon’s den.” Donatello would have been shocked if he wasn’t frozen in fear his father never bowed let alone asked for anything he took what he wanted! That only made Donny more fearful of the dragon fusion. And what was his father so afraid of sleeping in the den that he requested a legendary fusion’s help to only put it to rest? He was supposed to be in that cave for the next 6 months!
Black Kyurem growled and nodded before turning to look at Donatello. The dragon raised its hand and pointed at him. His father spoke up again “You can’t be serious Black you're telling me it’s waiting for him! What did my son do to anger a Sinnoh legend!” Kyurem shook its head and pointed more urgently. “What? Do you want him to go down there with us or something?” Kyurem nodded and Donny shook in fear. Before he finally spoke up “K-Kyurem you want m-me to go into the dragon’s den’s depths with you and father? I don’t even have a Pokemon yet you can’t be serious.” His father looked over at him “I’m sorry Donny but we don’t have time to try and compromise with black every moment is a moment it gets closer to the surface. Now hurry climb on!” His father leapt onto the dragon's back and offered an arm. Donny took it against his instinct to run because a dragon’s pride would never allow it to run away and that is what everyone in the Draco family was supposed to be. Dragons.
Donny kept still as Black Kyurem rose into the sky. Mostly because if he tried to do anything else he'd scream, and he had enough of being scared even if his father was nervous. Within moments they were at the entrance of the dragon's den and dove in.
Donny was stunned the whole cave despite being underground was lit up with an incredible blue tint. But the real reason he was stunned was the beauty of it all. A Salamance flew across his vision as it battled with a Flygon. A group of Noibat in the background flying steadily using sound waves to expertly traverse the stalactites as a group. Looking slightly down you'd see a Bagon jump off a cliff head first determined to fly despite having no wings, only to plummet to the floor and leave a huge hole with its tough head. A battle between dragons to rise a level in their pack on a plateau surrounded in a fight circle.

Even further down on the cave floor different packs of dragons walk around searching for their next prey. While some traversed alone in pursuit of strength and evolution. Before Donny realized they were flying deeper and deeper in the cave on a slant downwards. 2 hours of flying at top speed it wasn't so fun anymore. The deeper in the cave they got the warmer it got. Stronger dragons also appeared deeper in looking older, wiser and more battle worn. Until something shifted in the atmosphere, Donny didn't care about the heat anymore, in fact it was a cold sweat he felt now he was on edge the hair on his neck stood straight up. He could tell his dad felt the same thing though he looked accustomed to it.
Finally they came upon the source of this powerful aura, Donny couldn't describe the creature, it was a shock to him he had been tutored on dragon types his whole life he was sure he knew every dragon even the legends there was Kyurem, Reshiram, Zekrom, Eternatus, Rayquaza and the three whose existence wasn't confirmed Giratina Palkia and Dialga. But this... thing was unlike any dragon he'd ever seen. It was like a big crystal ball with 7 blue dots and nubby legs with what he had to assume were dragon bones for feet because of what looked like a Charizard skull split down the jaw for arms? The skull was huge too. "F-Father what in the name of Giratina is that?! is it even a dragon!" Donny yelled as they both hopped off Black Kyurem. His father ignored him to yell for Kyurem to use Freeze Shock. Kyurem, charged with electricity, held its hands out charging a ball of electricity with its unfrozen hand and ice with the frozen one. The dragon ball thing wasn't inactive though its arms, or that's what Donny thought they were, switched places the bottom half of the maw in between its legs and top half of the maw directly on top of its head as it began charging pure dragon energy to attack.
The charging took less then a second for both sides as the attacks collided Kyurem's winning out thanks to its ice typing and exploding upon impact with its target. The ball backed away clearly pissed and Donny's Father sent out 2 of his personal Pokemon. Druddigon and Dragapult hit the field looking prepared like this was something they'd done before firing of dragon pulse and dragon darts respectively. Donny tried speaking to his father again "Clearly you've done this before! Why not try and catch it? I saw there were master balls in the vault!" No response as his father continued to yell commands.
"Dragon claw! Hold it, Druddigon!"
"Dragapult you and your Dreepy distract it, pester it in any way!"
"Black charge up another Freeze Shock!"
All of the pokemon fulfill his orders perfectly. Druddigon despite intense struggle holds the maw apart canceling out its ability to use the powerful attack it had used previously. But Druddigon used a Dragon Dance to hold strong for 3 seconds. "Now release it Black!"
The charged freeze shock was blinding as it traveled at high speed towards the bound Pokemon. Druddigon looked terrified but steeled itself not to let go as the freeze shock collided with its prisoner. And by extension himself. The freeze shock exploded on impact frozen structures similar to lightning. When the light dissipated the ball fell to the floor, its blue circles now looking dim and the maw having fallen to the ground. Druddigon was frozen completely; it looked like an extremely detailed ice sculpture. For a second Donny thought Druddigon was dead but his father simply returned it to its pokeball.
"Donatello, you will not under any circumstance tell anyone what you saw here today. But commit the sight to memory, specifically the blue dots. Eyes. Whatever you want to call them if you see them run there are five of its kind including it. Then one above those 5 that is their leader and creator. Those six are possibly the strongest Pokemon on the planet besides unconfirmed existences. though this worry might be for nothing they are legendary Pokemon so it is unlikely you'll ever meet them." his father said sternly
Donny was too shocked to respond, the battle despite its short length was the most incredible thing he'd ever seen. It wasn't the type of battle that inspired or invigorated, but where most people would have been fearful Donny had been enamored. This was it that was the last piece of the puzzle for him, after being taught his whole life that dragons were the best this is the first time he'd truly seen them in action and it only confirmed what he'd been taught. They were the- "ABSOLUTE BEST! Father, I will meet all of them someday and I'll battle all of them!"
"Boy did you not listen to anything-"
"Come on, let's get back up to the upper levels!" Donny hopped up onto Black Kyurem's back and it nodded back at his father. This time it was Donatello who reached back and extended an arm to his father. with that they took to the air the ball retreating deep into the cave to rest.
It was a quick flight back to the upper levels, right as they were about to exit Donny took a leap from the dragon's back into a dive with perfect form. With a splash from the displacement of water Donny had officially entered the depths of the Dragon's Den.
So if you couldn't already tell the dragon ball pokemon was Regidrago I feel like I left enough hints in the chapter for people to guess.
