I only own my OCs
As they left the Poke-center, Korogra glanced back as he felt like he was forgetting something important. Turning back to the others he said, "If memory serves, the Indigo Plateau should be past Celadon City." Ash said, "That's actually perfect, I need to apologize to Erika for insulting her perfumes." Pikachu agreed, "Pi pika." Totodile asked, "Toto?" As Pikachu filled Totodile in, Korogra asked, "Let me get this straight... By insulting her perfumes, Erika denied you a battle so you had to cross dress to get in?" Misty said, "Exactly." Korogra said, "It goes against League rules to deny a challenger for something like that." Turning to Brock, he continued, "As former gym leaders you two should know that, and as his friends you should've helped him out so he wouldn't have to to what he did... I suppose I can let Brock off the hook as he was no doubt trying to flirt with her. But you Misty, what the hell!" Neither said anything as they realized their mistake.
Korogra went in through the perfume shop entrance and called, "Hey Erika?" She walked out and said, "Oh Korogra! What are you doing here?" Korogra said, "A friend of my has something to say." Erika looked confused and Ash came in and said, "Hey Erika, it's Ash. I wanted to say I'm sorry about insulting your perfumes. I was too focused on getting a gym battle." Erika was surprised and said, "It's alright I was too focused on my perfumes to remember denying a challenger like that was against league rules." They then shook hands and Korogra said, "Hey Erika, ever think about making men's cologne alongside your perfumes?" Erika stopped in her tracks and said, "No, I haven't if I do that not only could more money be made but the guys that come to challenge me wouldn't be overwhelmed by the perfumes. Thanks Korogra!" Nodding, Korogra said, "That takes care of that, anyway we should see if we need to pick up anything for the road ahead." Ash said, "Thanks for that Korogra." Korogra responded, "Hey, don't worry about it."
After they picked up some Pokemon food and other supplies, Pikachu noticed a glow from Ash's bag and took it out. Ash took it and said, "C'mon, we should get to the Pokemon Center my egg's about to hatch." Rushing off Brock asked, "What's the rush?" Korogra said, without stopping, "Ash's egg is about to hatch." Once at the Center, Ash said, "Nurse Joy, my egg's about to hatch. Do you mind looking it over one more time?" Joy said, "Of course Ash." After a quick but through check, she said, "Alright Ash, your egg is healthy as can be."
As she finished, the egg glowed brighter and the others backed up so it would first see Ash and imprint on him, even if Korogra had to force Misty away so it doesn't imprint on her. When the glow faded, it revealed a baby Dratini. Ash said, "Hey there little one, I'm your dad." The Dratini squealed and wrapped around Ash's arm and snuggled his face, laughing he said, "Alright Dratini, that tickles. Patting its head, he said, "Now Dratini, I'm going to scan you to see what you can do." Pulling out his Pokedex, it scanned and said, "Dratini: the dragon Pokemon. It is called the 'Mirage Pokemon' because so few have seen it. It's shed skin has been found. This Pokemon is male with the ability Shed Skin. Known moves: Wrap, Dragon Pulse. (Dragon Pulse is an Egg move that is currently locked)" Ash put the dex away and pulled out a pokeball then said, "Dratini, this is a pokeball. You'll have to go inside it so no one tries to take you from me." Dratini nodded and tapped the ball with his tail and was sucked inside, releasing it Ash said, "This is Pikachu, your older brother." Pikachu padded up and said, "Pi pikachu." As he gently patted Dratini on the head, Joy said, "Dratini, I'm Nurse Joy. I need to do a check up on you to make sure you're healthy." It looked at Ash who nodded, then returned itself so Joy could check it. Returning Joy said, "Dratini is perfectly healthy."
Ash said, "Thanks Nurse Joy." Outside Ash released his Pokemon and said, "Alright everyone meet the newest member of our family, Dratini." Ivysaur patted Dratini's head with a vine, Wartortle brushed his tail on Dratini's head causing it to let out a sneeze. Dratini wrapped itself around Charizard's tail and squealed as Charizard turned around, Pidgeotto tilted its head and Dratini mimicked it before squealing. Petting its head Ash said, "Alright Dratini, you're going to have to go in your pokeball for now. We've got quite a ways to walk before nightfall." Yawning he tapped the ball with his tail, putting the ball on his belt Ash said, "Heh, he must be tired. It's been an eventful day for the little guy. C'mon guys." They then left Celadon and made decent progress to the Indigo Plateau, when they stopped for the night Brock started cooking dinner for everyone. However when he turned to Ash about to ask if he needs something to feed Dratini he stopped slack-jawed as Ash juiced an Oran berry mixing it with some water and heating it over Charizard's tail before testing the temperature on his wrist and feeding Dratini, finally noticing Brock and Misty starring he said, "And here you thought I had no idea how to take care of a baby Pokemon, it's something Professor Oak gave a lecture on a couple years ago. I mean sure I can be super reckless but I usually know what I'm doing." Korogra turned from his work making food for his Pokemon and said, "Yeah, he even sent his Pokemon to patrol the area and report to Pikachu if they find anything unusual." Ash said, "Plus they'll keep an eye on Dratini when he decides to explore. And before you attack me with a mallet Misty, wild baby pokemon explore the area to get stronger. I mean honestly you didn't think Primape was always as strong as he was did you? He hatched the same as Dratini and was just as inexperienced."
Once fed Dratini started to wander unaware that Pidgeotto and Charizard were in the air above it, while Pikachu was leaping through the trees nearby and Ivysaur along with Wartortle were watching from the shadows. Dratini then saw a Rattata and approached. Ash's Pokemon watched carefully, ready to act if necessary. The Rattata noticed and scratched Dratini who looked shocked for a minute, Ash's other Pokemon were ready to step in but Dratini's expression changed from shock to anger and it wrapped its body around the Rattata and started to squeeze after a bit the Rattata shook Dratini off and tried to bite it but missed, Dratini then swung its tail at the Rattata hitting it hard before a blue orb formed in Dratini's mouth which it then launched as a beam. Scoring a direct hit sending the Ratata flying, when it landed it was knocked out. Pikachu jumped out of the tree and pat Dratini's head in congratulations for winning its first battle, it squealed before falling asleep. Pikachu then signaled Ivysaur and Wartortle to help it carry Dratini back to camp, Charizard nodded to Pidgeotto signaling that they should stick close in case another wild Pokémon attacks. Returning to camp, Charizard took Dratini as Pikachu ran up to Ash and told him what happened, he then walked over and held his arms out to Charizard who handed Dratini over. Misty was about to lash out when she saw Dratini sleeping, thinking it had been hurt only for the words to die out when Ash said, "Keep it down, Dratini is sleeping." He then set Dratini on his sleeping bag while he dug through his bag for a blanket, finding one he wrapped Dratini in and put him near his sleeping bag.
Korogra then returned with his Pokemon, seeing Dratini sleeping he said, "It's been a long day for Dratini hasn't it?" Ash nodded, "Yeah, hatching, traveling and his first battle. Turns out he learned Slam and Dragon Rage from a battle with a wild Rattata, I'm thinking of training a bit tomorrow." As he was getting ready for bed Korogra said, "Since Dratini's so young, I'd start with simple training on speed, power, and defense. Then after awhile you can start training him harder." Seeing his point he turned to his Pokemon and said, "Guys, tomorrow we're gonna train. There will be plenty of strong trainers at the league so we'll need to train hard, but since Dratini just hatched we'll start light to get him to the strength you had when I first caught you. Once he's at that point I'll swap one of you out for Krabby, who as far as I'm aware hasn't done much training since I caught him."
A/N: I'm gonna cut it here, next time I'll probably skip to the opening ceremony of the Pokemon League.
