Ash would likely become more responsible. Since Dratini is a relatively rare and potentially powerful Pokémon, he'd have to take extra care. This could make him think more before acting in battles and other situations.
It could be a legendary Pokémon in disguise. Legendary Pokémon sometimes interact with trainers in mysterious ways. This one could have chosen Ash to receive the Dratini egg as part of some grand plan to help Ash become an even greater trainer and perhaps save the Pokémon world from a future threat.
Dratini's character could be developed by showing its initial shyness. Since it's a relatively rare and often timid Pokemon, it might be scared of Ash at first. But as Ash shows kindness, Dratini could start to open up. Maybe it would show its playfulness when it gets more comfortable around Ash and the other Pokemon in his team.
In the fanfiction, perhaps Ash catches Dratini during a quest. He hears rumors about a rare Dratini in a certain area. He goes there and finds Dratini being chased by some other Pokemon. Ash steps in to protect it and earns Dratini's trust. The story could then focus on their adventures together, exploring new regions and facing tough opponents with Dratini by his side.
One popular story could be about Ash and Dratini's adventure in an uncharted forest. They might encounter rare Pokémon and have to work together to overcome challenges. In this story, Dratini could start evolving during a tough battle, which adds an exciting element.

His friends like Pikachu for sure. Pikachu would be there by Ash's side, probably as curious as Ash about the Dratini egg. Brock might also be involved. He could use his knowledge of Pokémon to give Ash some tips on taking care of the egg.
Well, in the fanfiction, Ash might start by being super excited about getting the Dratini egg. He could be very protective of it, constantly checking on it and making sure it's in a safe place. Maybe he'd research all about how to take care of a Dratini egg, like the ideal temperature and humidity.
The plot could involve Ash trying to get back to his normal form. He has to go on a journey as Dratini to find a way to reverse the transformation. Along the way, he meets other Pokemon who either help or hinder him.
