Then there's Cynthia. She is a very knowledgeable trainer. In the novels, she has a vast collection of Pokemon knowledge. Her Garchomp is a fearsome Pokemon. Cynthia's calm and composed nature in battles and her ability to analyze situations quickly make her a great Pokemon trainer.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
Charizard is often popular. Its large size and powerful abilities like Fire Blast make it an interesting Pokemon in a buried alive scenario. It could potentially use its fire to clear away debris or signal for help. Pikachu is also a common choice. With its electric powers, it might be able to zap its way out or use its cuteness to attract other Pokemon to help. Another popular one is Eevee. Because of its potential to evolve into different forms, fanfiction writers can play around with how it might adapt to being buried alive and what form it might evolve into to escape.
In Pokemon Sato and Lila fanfiction, some of the most popular Pokemon are those that are both cute and powerful. For example, Sylveon. It's an Eeveelution that has a very charming look and strong fairy - type moves. Another popular one is Lucario. It has a cool design and its aura - based abilities are really interesting in the stories. And of course, Gardevoir. It's not only beautiful but also has strong psychic powers that can be used in various plotlines.
I think Lucario would be an interesting addition. It's a very intelligent and powerful Pokemon. It could sense danger and help Ash make better decisions. Also, Squirtle is a fan favorite. Its cute appearance and water - type abilities can add a lot of fun to the story, especially in water - related adventures.
Ash is of course a very common character as he is the central figure. Pikachu is also often included as it is Ash's most well - known Pokémon. Other characters like Misty and Brock might also make appearances as they are Ash's friends and travel companions in the original Pokémon series.
It could be a group of Team Rocket - like villains. They are after the unique powers that the reborn pokemon might possess. Since the reborn pokemon has a human - like intelligence, they see it as a valuable asset to use for their evil plans, like stealing all the precious pokemon resources or taking over a certain region.
Shelly in Pokemon fanfiction is often a trainer. She could be a new trainer starting her journey, excited to catch and train different Pokemon. Maybe she has a particular goal, like becoming a Pokemon master or specializing in a certain type of Pokemon battles.
Damian might be a character who has a special connection to a certain legendary Pokemon in fanfiction. For example, he could be on a quest to find and communicate with a legendary Pokemon that is said to hold great power. His journey would be filled with challenges and revelations as he tries to get closer to this Pokemon.
